Answer:
The daughter cells need a copy of every chromosome in order to replicate and separate.
Explanation:
Cells have to replicate their genetic material to make a whole other cell. Before mitosis the cells need this step for mitosis.
<span>B. A prokaryotic cell does not have nucleus and the other one does. The most defining characteristic of eukaryotic cells is their true nucleus. Prokaryotes lack true nucleus</span> and membrane bound organelles.
Answer: look at the screenshot
Answer:
The following are the sections which can be seen in a food label:
1) Product dates:
Under this section look for the production date and the expiry date ( best before). The production date tells when the food was made. The expiry date tells the date before which the food has to be used.
2) Ingredient list:
The list of all the ingredients used for the preparation of the food is mentioned.
3) Nutrition Facts Label
At the top of this label, we will see the total number of servings and size of the container. Thus table shows some key nutrients and the percent of them present in the container of food. It also shows the calories of each. Percent Daily Value (DV) shows the percentage of each nutrient present.
The nutrient label are important to an athlete because he/she needs to take a diet which is capable of filling us nutrient requirements. Athletes tend to perform well when they have a balanced diet. To get a balanced diet, they need to look at the nutritional values.
Answer:
Pleiotropy
Explanation:
Pleiotropy is a genetic condition in which a single gene conditions the expression of multiple phenotype. There are different types of pleiotropy depending on the underlining mechanism
- <em>gene pleiotropy</em>
- <em>developmental pleiotropy</em>
- <em>selectional pleiotropy</em>
- <em>antagonistic pleiotropy </em>
<em>Phenylketonuria is a disease characterized by increased level of amino acid phenylalanine in the blood. It caused by mutation to the gene responsible for breaking down phenylalanine in the blood. Elevated level of phenylalanine causes other issues such as mental problems, urine coloration and reduction in skin pigmentation. This is a clear case of pleiotropy.</em>
