.....culturing viruses that requires a human host
Answer:
Diploid cell culture lines, developed from human embryos, are widely used for culturing viruses that require a human host
Explanation
Viruses can not thrive in a non-living host or artificial media.They are intracelular parasites which needed living host to replicate . Cultures lines from Human embryo in are therefore used for culturing viruses of human host, so that its mode of replication and gene expression can be studied, and therefore its virulence can easily be studied.
This method have the advantage that;
1.there is no need to make use of the whole animal rather,on a tiny tissue needed can be isolated for culture.
2. the cells growth is continuous,and can be preserved in liquid Nitrogen and renew for future culture
3. cells can be grown in different containers, with ability to decide the number of cells needed.
Temperature is kept at optimum for human in the culture at 37 degree centigrade, nutrients are provided, NaHC03 as buffers for C02, and the medium is humidified.

Answer: alleles
Explanation:
Alleles are different forms of a given gene. Alleles are mutated forms of a given gene which controls a particular trait. For instance, the gene that codes for hemoglobin is denoted with the letter A but the gene has another variant denoted by S. In abnormal hemoglobin S (sickle hemoglobin), glutamate is replaced by valine at position 6 in the amino acid sequence of the two beta chains of hemoglobin. This change in the amino acid sequence causes the red blood cells to have a sickle shape resulting in sickle cell disease. Therefore hemoglobin A and S are alleles of a given gene.
- The anterior pituitary gland's endocrine cells are in contact with hormones that are released.
- Neurosecretory cells in the hypothalamus secrete hormones that are released.
- Release of a specific hormone into the bloodstream by endocrine cells in the anterior pituitary gland.
<h3>What is the main function of the hypothalamus?</h3>
Your body's sophisticated control and coordination center is located in your hypothalamus, a structure deep inside your brain. Its major job is to maintain homeostasis, a constant state of equilibrium in your body. It carries out its function through controlling hormones or by directly affecting your autonomic nervous system.
<h3>What are the endocrine cells?</h3>
The gut's endocrine cells are a significant source of the hormones that regulate metabolism, digestion, and appetite. They are mostly found in two places: islets in the pancreas and sporadic clusters in the mucosal epithelium of the gut.

The answer is A, as bears don’t eat deer, but they both eat plants.
Heterotrophs are animals.
Autotrophs are plants.
Hope this helps!
