The first one. Becuse there are more grey particuls, wich difuse faster.
So both the rabbits are Bb which means there will be a chart which comes out with one BB, Two Bb and one bb, For the rabbit to become brown fur it would need to get bb from theirs parents reproducing, if it's Bb they will just carry the trait recessive trait again and if it's BB they won't be carrying the trait
Answer:
A cap is added to the 5 end of the mRNA
Explanation:
In prokaryotes, the translation process takes place simultaneously with the transcription but the mRNA molecule after synthesis undergoes some post-translation modification which protects the mRNA from the cytosolic environment.
One of these modifications is known as capping which refers to the addition of the cap at 5' end of the mRNA. This cap is added by an enzyme called guanyl transferease and protects the end of the mRNA.
Thus, the selected option is correct.
The answer that I had think it is c.
Answer: both parathyroid hormone and calcitrol.
Explanation:
In the body calcium homeostasis, which is generally defined as the maintenance of specific internal conditions, is mediated by the endocrine system through hormonal control; hormones are usually specialized signal molecules derived from lipids or amino acids. This regulates the calcium flux between the bloodstream and the bone; and the hormones responsible, change the ratio of osteoclast activity to osteoblast activity -osteoblasts build bone while osteoclasts breakdown or degrade bone.
Hormones responsible include calcitonin (from special parafollicular cells in the thyroid gland), cacitrol (activated vitamin D) and the parathyroid hormone (from the parathyroid glands). These affect the absorption of calcium from the gut, or kidney reabsorption; both parathyroid hormone and calcitrol act by causing the release of calcium ions into the bloodstream as the bone is degraded by osteoclasts.
