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 ❤️❤️❤️

Which of the following does NOT describe a fluid?
Answer:
list them
Explanation:
Answer:
plz list the answers :)
Explanation:
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.

What 3 systems get put to work when a beaver is building a home and how?
Answer:
beaver dams smooth out water flow by increasing the area wetted by the stream. This allows more water to seep into the ground where its flow is slowed. This water eventually finds its way back to the stream. Rivers with beaver dams in their head waters have lower high water and higher low water levels.

Altos niveles de ATP en la célula son necesarios para realizar ciertas funciones vitales tales como reproducirse.A qué piensas que se deba esto
Answer:
el ATP es la moneda energética que la célula utiliza para llevar a cabo diversas funciones metabólicas (incluida la reproducción)
Explanation:
La adenosín trifosfato (ATP) es la principal fuente de energía para la mayor parte de los procesos celulares. La hidrólisis del ATP libera energía química almacenada en los enlaces de fosfato de la molécula, la cual es utilizada por la célula para llevar a cabo diversas funciones, incluida la reproducción. La hidrólisis de ATP genera en primera instancia adenosín difosfato (ADP) y un grupo fosfato libre (ortofosfato), esta es una reacción exergónica que libera una enorme cantidad de energía la cual es utilizada por la célula para llevar a cabo diversas funciones metabólicas incluyendo la síntesis de macromoléculas tales como, por ejemplo, proteínas del huso mitótico requeridas durante el proceso de división celular. El ADP también puede hidrolizarse para liberar energía, con la consecuente producción de adenosín monofosfato (AMP) y un segundo fosfato libre.
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.

Can someone tell me what's the syllabus taught in American high schools, like in 10th grade? I'm not an American student and I'm just curious. (didn't mean to sound creepy). thank you so much.
Before higher education, American students attend elementary and high school for a combined total of 12 years. These years are known as the period from first grade to twelfth grade.
At the approximate age of six, American children begin elementary school, which is exclusively called “elementary school” (elementary school). They attend this school for five or six years and then go on to high school.
High schools are made up of two programs: the first is called "middle school" or "high school" (middle school) and the second is called "high school" (high school). A diploma or certificate is awarded upon graduation from high school. Upon graduation from high school (twelfth grade), American students can go on to college or university. Studies at a college or university are known as "higher education."

Can you describe a frogs metamorphosis, including whether it is complete or incomplete
Answer: frig metamorphosis is complete
Explanation:
This is because in complete metamorphosis, frog develop from egg to adults. Metamorphosis refers to change of shape and growth in different stages of animals life cycle.
Frog mate in the rainy season.
There are four stages of frog metamorphosis and they are;
1 Egg : the female mate with the male and the male fertilizes the egg. The female releases the fertilized egg inside water , they egg are jelly like or cover with jelly covering.
2. Tadpole: the egg then hatched into tadpoles. The tadpoles live in water, it does not have lungs and limbs. It move like fish and uses gills to breathe. At this stage it starts developing hind limbs and later lungs. It has long tail
3. Froglet : At this stage, the lungs and the front legs develop. It floats above the water to breathe. The tail become shorter and it uses nutrients stored in the tail to feed or survive.
4. Adult : this is the final stage, the young frog leave water and start live on land, it's tail disappear completely and it's start feeding on insects.

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.
What 3 systems get put to work when feeding and how does each one work when you eat?

Summarize taste considerations.
The word taste, or gustation, to give its full name, refers to what is detected by the taste cells, located on the front and back of the tongue and on the sides, back and roof of the mouth. These receptor cells, or taste buds, bind with molecules from the food or drink being consumed and send signals to the brain.
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.
How is cellular respiration a chemical process in which the bonds of food and oxygen molecules are broken and the bonds in new molecules are formed resulting in a release of energy
Here is some information you need to answer this question:
Cellular respiration equation:
C6H12O6+6O2 -> 6CO2+6H2O
Cellular respiration breaks the glucose (C6H12O6) molecules for energy and new molecules (CO2 and H2O are formed as byproduct).
Overall, there is a release in energy, but also more so of a net increase of energy.

Answer:
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.
