Answer:
E site will be empty as it is exit site for protein synthesis.
P site will have code AUA with three amino acids because it is the site for peptide synthesis.
A site will have UCC code with one amino acid because its the code for serine synthesis. Moreover, A site is binding site for charged t-RNA molecules during protein synthesis.
Lady bugs are carnivores. If you want to get more technical they are insectivores. This is because they only eat soft bodied insects/arachnids like aphids, mites, and scale insects.
Answer:
Most cells within planarians tend to be very close to their gastrovascular cavity, in addition to their external environments. Also, planarians have the ability for oxygen and carbon dioxide to diffuse through the cells on their body walls: this makes it unnecessary for these varieties of flatworms to need a dedicated bodily system.
I think the deficiency of dedicated respiratory and circulatory systems in Planarians does not cause a problem because none of their cells are far removed from the gastrovascular cavity or from the external environment. Planarians are free-living flatworms and form the class Turbellarians in the Phylum Platyhelminthes. Flatworms have three tissue layers, that is the ectoderm, mesoderm, and endoderm.
hope this helps!!!!!....
Explanation:
<span>This research study would be a prospective cohort study. </span>
<span>In this study, the groups are different in some way, for example, a control group which received no treatment, a standard group who received a well-studied drug and a test group who received a new drug. These groups are followed over time and the outcome (such as curing a disease or alleviating symptoms) will be compared. </span>
T<span>he MAIN way the skin prevents pathogens from entering the body is B. by acting as a barrier.
Our skin is a barrier between blood and tissues inside and everything found outside of our body. The skin protects us from various kinds of pathogens by shielding us from them.
