Describe the process of creating a designer baby.
Answer:
The term 'designer baby' refers to a baby that has been given special traits through genetic engineering. This is done by altering the genes of the egg, sperm, or embryo. These traits can, in theory, vary from lower resistance to diseases to even gender selection

Explanation:
Both metamorphic and igneous rocks have crystals. How could we tell the difference between the two types? What would you look for?
Answer:
igneous rock does not usually have a definite crystal shape
Explanation:
because it is formed from molten magma. after it is cooled and dried. anything caught by the molten magma retains it's shape after cooling
In the diagrams of mitotic cell division shown, which structure is present in diagram B but in diagram A?
-centriole
-cell plate
-cell membrane
-cytoplasm
Answer:
-cell plate
Explanation:
Diagram A is an animal and diagram B is a plant cell. When dividing through mitosis plant cells form a cell plate during the mitotic phase. However, cell plates are not found in animal cells, as they do not have cell walls. Therefore, the answer must be cell plate.
what would happen if the igneous rock was first exposed to energy from the sun
Answer:
If there is too much heat or pressure, the rock will melt and become magma. This will result in the formation of an igneous rock, not a metamorphic rock. Consider how granite changes form. Granite is an igneous rock that forms when magma cools relatively slowly underground
Explanation:
Answer:
An igneous rock can change under pressure to metamorphic. A igneous rock can turn into another igneous rock by melting and solidifying, it can turn into a sedimentary rock by getting weathered then recemented, or it can turn into a metamorphic rock by being subjected to great heat and pressure

Differentiate the components of fluid connective tissue?
Answer:
The components of the fluid connective tissue are red blood cells, white blood cell and blood platelets
Explanation:
The connective tissues refer to tissues composed of some class of matrix. The blood is considered a fluid connective tissue which is composed of red blood cells (erythrocytes), white blood cell (leukocytes) and blood platelets (thrombocytes). Erythrocytes are cells that contain hemoglobin and whose function is to transport oxygen to the body. Leukocytes are cells involved in the immune responses which act to protect the body against both foreign pathogenic invaders. Finally, thrombocytes are cell fragments that form clots and stop bleeding.

+jjjjjjjjjjjjjhj
The long-term effects which may arise from the use of genetically modified crops is a controversial issue associated with the use of GM crops. They are reported to be having serious health impacts.
What is genetically modified crops ?Some crops are designed using genetic techniques to insert them some desired characteristics such as microbial resistant, high yield, taste, bigger size etc. Genetic engineering techniques such as CRISPER genes are common today to modify the crops in order to meet the desired features.
Genetically modifying food is a relatively new process, thus it is unclear how it will affect food safety in the long run. Human health is a major concern with regard to the drawbacks. While study is ongoing, scientists have not yet demonstrated that eating GMO foods is unhealthy.
Allergic reactions, genetic changes, devastations of good insects and their diversity etc. are the drawbacks of GM crops. Some even leads to cancer. Hence, option A is correct.

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.

The items that are inferential statistics among the options would be:
Give the likelihood of data occurring by chanceTell you whether to call your mother about your resultsGive a measure of statistical significanceThis is largely due to the fact that inferential statistics refer to the branch of statistics that draws conclusions from a set of data. It is as opposed to descriptive statistics which focus on summarizing, describing, arranging, and or categorizing data in such a way that trends are shown at a glance.
Statistical parameters such as mean, mode, and median only measures attributes of data relating to the measure of central tendencies. Data summary is purely descriptiveHence, the items selected are those that are conclusive and not descriptive.

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?

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.
