Answer:
A; P; E
Explanation:
A tRNA molecule is a type of RNA found in the ribosomes of a cell. They play a major role in the translation process by binding to the mRNA in respective sites of the ribosome and carrying their corresponding amino acid to the growing polypeptide chain.
Ribosomes, which is the site of translation has three sites namely: A site, P site, and E site. tRNAs perform their roles by moving through these sites in the order: A to P to E.
Site E is the release site

why is cytoplasm present in all cells?
Answer: Cytoplasm is present in all cells because it is the placeholder of the cell. It helps to fill in the cell and holds all the organelles in their place. If the cell did not have cytoplasm, the cell would be deflated and some certain materials would not have the ability to pass easily from one organelle to another. Hope this helps!

describe the chromosomal difference between sex cells and a zygote (fertilized egg)/ body cells
Answer:
The main difference between sex cells and zygote is the chromosomal charge, where the sex cells have half of the chromosomes haploid and the zygote has the full load, is diploid, as well as the body cells.
Explanation:
Ploidy is based on the number of chromosomes found in a cell:
If the cell contains the full charge of chromosomes it is called a diploid (2n). This occurs in body cells and in the zygote. When a cell contains half the charge of chromosomes, it is called haploid (n), and it only occurs in gametes or sex cells.The reason for this difference is that the gametes go through a process of reductional division, called meiosis. They are haploid because when the gametes of the parents unite —during fertilization— they give rise to a haploid cell, the zygote.
How might a reduction in species diversity affect the other three components of biodiversity?
Answer:
if the species diversity in an ecosystem or on the Earth gets reduced, it will affect the balance biodiversity and its other components. The three components of biodiversity are: ecosystem, species, and genetic diversity.
Biodiversity is defined as the variety of life forms existing in different ecosystems on planet Earth.
The three components of biodiversity are:
genetic diversity, species diversity, ecosystem diversity.If there is a reduction in the species diversity, there will be an imbalance in biodiversity, which is integrated, where each living being has an essential role in the maintenance and sustainability of the planet.
Biota reduction will therefore directly impact the ecosystem and will alter the correct flow of environmental balance.
It is possible to see through history, that many species of animals were extinct by human exploitation and this action cannot be reversed.
Therefore, it is essential to make each individual aware of the importance of developing sustainability for the preservation of nature and the quality of life of current and future generations.

One of the most common sources of phosphate pollution that has led to eutrophication has resulted from the use of
Answer:
Phosphate fertilizers
Explanation:
One of the most common sources of phosphate pollution is run-offs from phosphate fertilizer from agricultural processes. Farmers deploy phosphate-containing fertilizers to soils in other to improve the overall fertility of the soil and the yield of crops.
Some of these fertilizers find their ways into nearby water bodies through washing up by erosion thereby raising the phosphate levels of these water causing eutrophication.
Other common sources of phosphate pollution include industrial and domestic run-off as well as detergents although phosphate-containing detergents are now becoming a thing of the past.

Explain why your results of the optimal temperature of the lactase enzyme make sense for the human enzyme
Answer:
Because the human body is below 40degrees Celsius which is the optimal temperature of the lactace enzyme.
At the optimal or average body temperature of the body the human body, the nature of the lactase protein is not denatured.
Explanation: Lactase enzyme is produced in the cells of the small intestine of humans and most mammals,the main function of the Lactase enzyme is to ensure the digestion of sugars that are present in the milk and other dairy products consumed by both humans and other mammals.
The optimal temperature of the lactase enzyme is 40degrees Celsius which means it can successfully fulfill and perform its functions within the human body whose temperature is generally below 40degrees Celsius.

Both hexokinase IV and hexokinase I phosphorylate glucose at carbon-6. What properties of hexokinase IV make it important for maintaining stable blood sugar levels
I am going to explain the properties of hexokinase IV and it's properties that make it important for the maintainance of stable blood sugar level.
Hexokinase as well as Hexokinase IV all phosphorylate the glucose at C-6, Because Hexokinase IV has a low affinity with glucose and it is expressed in the liver,so it does have a way of maintaining blood sugar level.
When the blood glucose is low generally,it isn't saturated or working,but when the blood glucose gets high,it becomes transactivated and the activity of glucose 6 phosphatase results in low blood glucose.
Therefore,the most important activity of
Hexokinase IV is the regulation of blood glucose levels.
4. Affinity chromatography can often be used to purify one specific antibody from animal blood serum in a single step, even though serum typically contains around 10 billion different antibodies and also includes many other types of proteins. Explain why this is true. If necessary, do some online research about antibodies first. g
Answer:
Affinity chromatography is a technique based on specific binding interactions
Explanation:
Affinity chromatography is a technique used to separate and identify macromolecules by their specific binding biological interactions. This technique enables the identification of macromolecules that establish specific types of binding interactions including, among others, antigens and antibodies, receptors and ligands, etc. Affinity chromatography is the most widely used technique for antibody purification because this method has high selectivity and enables to concentrate the target molecule in a single step. Antibody fragments such as single-chain variable fragments (scFV) can be purified by affinity chromatography when they are covalently immobilized to a solid support (for example, agarose beads).

WHAT'S THE DIFFERENCE BETWEEN INCOMPLETE DOMWANCE AND CO-ODOMINANCE ? GIVE EXAMPLES OF THE BOTH INCOMPLETE AND
CO-ODOMINACE. USE THE PUNNET SQUARE TO SUPPORT YOUR ANSWER
Answer/Explanation:
Incomplete dominance is when one allele is not entirely dominant over the other, resulting in an intermediate phenotype. Example could be in flower colour. F is the allele for red flowers, f is the allele for white flowers. Let's cross a red flower (FF) with a white flower (ff):
F F
f Ff Ff
f Ff Ff
100% of the offspring are Ff. F is in completely dominant to f, so all the offspring have an intermediate phenotype - all the flowers are pink.
Co-dominance is when neither allele is dominant and both alleles are expressed equally. An example is in human blood types. A and B alleles are both dominant to the O allele, but co-dominant to each other. Therefore, if an individual who is AO has children with an individual who is BO:
A O
B AB BO
O AO OO
The individual would either be blood type O (OO), blood type A (AO), blood type B (BO) or blood type AB (AB)
