Which statement is the best decription of how blood circulates through the body?
A. The circulatory system pushes blood upward throughout the body
by using gravity
B. The heart contracts and relaxes causing a force to push the blood
throughout the body.
C. The respiratory system pulls the blood inward when inhaling and
pushes it outward when exhailing.
D. The blood circulates throughout the body by gravity only.
The blood circulates throughout the body because of the contraction and relaxation of the heart which pushes the blood throughout the body. So, the correct option is B.
What is the circulatory system?The circulatory system is a specialized system for the circulation of blood throughout the body. This blood is rich in nutrients obtained from the digestive system after digestion and oxygen obtained from the respiratory system after breathing.
The circulatory system is like an industrial pipeline system in which a pump or motor, pipes and the component flow through the pipes.
The blood vessels represent the pipes. There are two types of blood vessels, the arteries and the veins which carry oxygenated and deoxygenated blood respectively.
The blood is the component flowing through the blood vessels. The blood is a liquid tissue, in which the liquid component is called the plasma and the cellular component is represented by three types of cells. These are the red blood cells, white blood cells and platelets. The nutrients flow freely in the blood plasma and oxygen is carried by the Red blood cells.
The heart is the pump of this system, it contracts to push blood through the blood vessels and relaxes to allow blood into its chambers. The human heart has four chambers.
Therefore, the correct option is B.

90% H2O 10% Solute The solution is: hypertonic / hypotonic / isotonic Water will: not move / move into the cell / move out of the cell
Answer:
Hypotonic / moves into the cell.
Explanation:
Hope you have a nice evening.
The solution is hypotonic. Water will move into the cell.
What is hypotonic solution?A hypotonic solution is one where the concentration of solutes outside the cell is lower than the concentration inside the cell. In this case, the solution is composed of 90% water and 10% solute, which is a lower concentration of solutes than inside the cell.
As a result, water will move into the cell in order to balance the concentration of solutes and maintain homeostasis. This can cause the cell to swell and may even lead to lysis if the cell is unable to handle the increased volume.

A stick insect has body parts that look like sticks and are a similar color to the trees
they live in. How does this help the stick insect to survive?
Glucose provides energy for cells. Different cells have different mechanisms for glucose intake. Intestinal cells contain proteins that transport glucose against its concentration gradient. These proteins couple the movement of glucose to the movement of sodium down its concentration gradient. Red blood cells have transporter proteins embedded in their membranes. When bound by a glucose molecule, these proteins change shape and allow glucose to move down its concentration gradient into the cell.
Based on this information, what type of transport is used for glucose in blood and intestinal cells?

A. Describe the role of the promoter in eukaryotic gene expression. Explain how a negative regulatory molecule could inhibit transcription at the promoter.
B. Identify TWO events that occur during RNA processing. Explain how RNA splicing increases the variation of mRNA molecules.
C. Describe the role of miRNA in gene expression.
Answer:
Explanation:
A. The role of promoter in eukariotic gene expression is It is to bind transcription factors that regulate transcription initiation. This molecule is so important because control the binding of RNA polymerase to DNA. The promoter region may be short or very long; the longer the promoter is, the more protein binding space is available. A negative regulatory molecule has the possibilty to inhibit transcription at the promoter because these molecules block the binding of RNA polymerase to the promoter region, thus not allowing the initiation of transcription, in some particular cases, the negative regulator binds to the lac repressor and will bind to the promoter in the same site where RNA polymerase would bind to.
B. Two process that occur during RNA processing are RNA splicing and 5′ capping, 3′. RNA splicing is a procces known for removing the introns from the pre-RNA and stuck back together the restant parts, exons. This process has as a goal form a mature mRNA that does not contain the intron sequences. RNA splicing has effect on variation of mRNA molecules because through a process called alternative splicing more than one mRNA can be made from the same gene.
C. Even though they are not quite the same thing miRNA and negative regulatory molecules have the same role, which is inhibit the translation and silence genes. They regulate gene expression by binding to the 3'-UTR of their target mRNAs and destabilizing the mRNA and translational silencing, repressing protein production. Even so, under specific circumstances, miRNA can activate translation or regulate transcription.

How do your cells know what to do? Just like builders have blueprints to tell them how to build a house, your cells also have instructions. Your cells' instructions are molecules of DNA.
What is DNA?
DNA is the material that makes up our chromosomes and stores our genetic information. When you build a house, you need a blueprint, a set of instructions that tells you how to build. The DNA is like the blueprint for living organisms. The genetic information is a set of instructions that tell your cells what to do.
DNA is an abbreviation for deoxyribonucleic acid. As you may recall, nucleic acids are a type of macromolecule that store information. The deoxyribo part of the name refers to the name of the sugar that is contained in DNA, deoxyribose. DNA may provide the instructions to make up all living things, but it is actually a very simple molecule. DNA is made of a very long chain of nucleotides. In fact, in you, the smallest DNA molecule has well over 20 million nucleotides.

According to the diagram below how are metamorphic rocks formed
A. Wastes deposited by plants and animals decompose and weather
B. Other rocks experience intense heat and pressure
C. Sand and other particles are buried,compacted, and cemented together
D. Molten rock cools and turns solid
When rocks are exposed to extreme temperatures, high pressures, hot mineral-rich fluids, or, more frequently, some mixture of these conditions, metamorphic rocks are created. These kinds of conditions can be obtained deep within the planet or where plate tectonics collide.
What two processes result in metamorphic rocks?Heat and pressure cause an existing rock to change into a new rock, creating metamorphic rocks. When hot magma hits rock, contact metamorphism takes place. Under the intense heat and pressure produced by tectonic forces, regional metamorphism changes substantial portions of existing rocks.
Most metamorphic rocks are formed where?The majority of metamorphic rocks are formed underground. Extreme pressure and heat are used to produce them. This includes any procedure where heat, force, or the use of chemical fluids change the structure or makeup of a rock while it is still solid.

Hello! I have to write an essay based on the Water Cycle and what it is/does. I will give Brainliest for the correct answer. I will also give 20 points to whoever writes the essay, and has the correct answer. Good luck.
Answer: The water cycle also known as the hydrolic cycle describes the always foward rotation above and below the surfaces of the earth. The mass of water on earths surface remains fairly consistant. However, the water splits up into diffrent groups, freshwater, saline water, ice, and atmospheric water. The water can travel between catorgories such as river to ocean or ocean to atmosphere through evaporation, condensation, precipatation, surface runoff and subsurface flow. When water go through these physical process it can change aswell such as being a liquid, solid,and gas. During evaporation it takes water from it surroundings and cools its enviromwnt,
the exchanges in heat fluctuate the climates tempature.
PLS HELP! THANK YOU! :) explain the structure of plant organs and the adaptations plants have for pollination, fertilisation, dispersal, germination and plant growth
Explanation:
Introduction
Plants have evolved different reproductive strategies for the continuation of their species. Some plants reproduce sexually while others reproduce asexually, in contrast to animal species, which rely almost exclusively on sexual reproduction. Plant sexual reproduction usually depends on pollinating agents, while asexual reproduction is independent of these agents. Flowers are often the showiest or most strongly-scented part of plants. With their bright colors, fragrances, and interesting shapes and sizes, flowers attract insects, birds, and animals to serve their pollination needs. Other plants pollinate via wind or water; still others self-pollinate.
Asexual Reproduction
Vegetative reproduction is a type of asexual reproduction. Other terms that apply are vegetative propagation, clonal growth, or vegetative multiplication. Vegetative growth is enlargement of the individual plant, while vegetative reproduction is any process that results in new plant “individuals” without production of seeds or spores. It is both a natural process in many, many species as well as a process utilized or encouraged by horticulturists and farmers to obtain quantities of economically-valuable plants. In this respect, it is a form of cloning that has been carried out by humanity for thousands of years and by plants for hundreds of millions of years. Sexual Reproduction and The Flower
The flower is the reproductive organ of plants classified as angiosperms. All plants have the means and corresponding structures for reproducing sexually. The basic function of a flower is to produce seeds through sexual reproduction. Seeds are the next generation, serving as the primary method in most plants by which individuals of the species are dispersed across the landscape. Actual dispersal is, in most species, a function of the fruit (a structural part that typically surrounds the seed).

Plants and sexual reproduction: Plants that reproduce sexually often achieve fertilization with the help of pollinators such as (a) bees, (b) birds, and (c) butterflies.
Sexual Reproduction in Gymnosperms
Gymnosperms produce both male and female gametophytes on separate cones and rely on wind for pollination.
image
Male and female gametophytes: These series of micrographs shows male and female gymnosperm gametophytes. (a) This male cone, shown in cross section, has approximately 20 microsporophylls, each of which produces hundreds of male gametophytes (pollen grains). (b) Pollen grains are visible in this single microsporophyll. (c) This micrograph shows an individual pollen grain. (d) This cross section of a female cone shows portions of about 15 megasporophylls. (e) The ovule can be seen in this single megasporophyll. (f) Within this single ovule are the megaspore mother cell (MMC), micropyle, and a pollen grain.
Female Gametophyte
The female cone also has a central axis on which bracts known as megasporophylls are present. In the female cone, megaspore mother cells are present in the megasporangium. The megaspore mother cell divides by meiosis to produce four haploid megaspores. One of the megaspores divides to form the multicellular female gametophyte, while the others divide to form the rest of the structure. The female gametophyte is contained within a structure called the archegonium.
Reproductive Process
Upon landing on the female cone, the tube cell of the pollen forms the pollen tube, through which the generative cell migrates towards the female gametophyte through the micropyle. It takes approximately one year for the pollen tube to grow and migrate towards the female gametophyte. The male gametophyte containing the generative cell splits into two sperm nuclei, one of which fuses with the egg, while the other degenerates. After fertilization of the egg, the diploid zygote is formed, which divides by mitosis to form the embryo. The scales of the cones are closed during development of the seed. The seed is covered by a seed coat, which is derived from the female sporophyte. Seed development takes another one to two years. Once the seed is ready to be dispersed, the bracts of the female cones open to allow the dispersal of seed; no fruit formation takes place because gymnosperm seeds have no covering.
How does DNA send it's instructions to the other parts of the cell?
Answer:Through mRNA, the DNA is able to transmit its messages out to other parts of the cell. (Learn more about mRNA here.) Information from the DNA is coded into mRNA which leaves the nucleus of the cell DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies (the white region) and is used by ribosomes (outlined in green). hope this helps have a great night ❤️❤️❤️
Explanation:
Why do you think having such an extensive membranous area is beneficial when performing photosynthesis?
Answer:
Increasing the membrane area also increases the number of ATP and NADPH generating sites
Explanation:
Photosynthesis occurs in the chloroplast, more precisely in the membranes of the thylakoids that form stacks of disks called grana. A mature chloroplast may have 20 to 60 grana. In these membranes, there are photosystems, which are structural units of pigment-protein complexes that convert light energy from the sun into chemical energy stored in ATP and NADPH. A thylakoid may contain thousands of photosystems. In consequence, increasing the membrane area also increases the number of photosystems required for the synthesis of ATP and NADPH.
