Answer:
<u>Villus- </u>It is a worm like processes on certain membranes, especially on the mucous membrane of the small intestine, where they serve in absorbing nutriment.
<u>Capillary-</u>Any of the fine branching blood vessels that form a network between the arterioles and venules.
<u>Alveolus- </u>These tiny, balloon-shaped air sacs sit at the very end of the respiratory tree and are arranged in clusters throughout the lungs.function it is to exchange oxygen and carbon dioxide molecules to and from the bloodstream.
<em>Now, they are all present at a very basic level and some how there are similarities between there nature of operations.</em>
Explanation:
- Both alveoli and villi help in increasing surface area of the respective organ. As they increase the region of operations for the respective organ, on which they are present on.
- As both alveolus and villus are associated with extensive blood capillary network for diffusion of important substances into blood: namely oxygen and dietary nutrients.
- And the most important thing all of them are present on a minute level of the bodily operations.
Answer:
A dolphin breathes through a single blowhole on the top surface of its head. The blowhole is covered by a muscular flap, which provides a watertight seal.
A dolphin holds its breath while below water.
The dolphin opens its blowhole and begins to exhale just before reaching the surface of the water. To open the blowhole, the dolphin contracts the muscular flap.

The correct is option (C) includes bacterial genes that produce a toxin that reduces damage from insect pests.
Due to advancements in plant biology, some plant species can now incorporate unique traits that are typically not found in their species. New and improved plant strains can be created using plant biotechnology. This technology is heavily utilized to advance agriculture.
A particular crystalline insecticidal protein is created by combining a specific gene sequence from the bacteria Bacillus thuringiensis with plants. Bt plant is a common name for these transgenic plants. One such transgenic plant that protects transgenic maize from damaging insects and pests is bt maize.

Answer:
there must be large numbers of free amino acids present in the cytoplasm
Explanation:
<em>In order for translation to occur, </em><em>there must be a large number of free amino acids in the cytoplasm.</em>
<u>These free amino acids are usually carried by the transfer RNA which also carries the corresponding mRNA codon.</u>
During translation, as the codons in the mRNA match their complements in the tRNA, the amino acid being carried by the tRNA is released and a peptide bond is formed between subsequent amino acids until the required polypeptide bond is formed.
Translation and transcription only occur simultaneously in prokaryotic cells where there is no barrier between the cell's genetic materials and the cytoplasm, unlike in eukaryotic cells where the genetic materials are housed in the membrane-bound nucleus.
