The actual answer (sorry for the late reply, but this is for the rest of the people coming afterwards) would actually be B) Switch primitive reptile with primitive insect. Insects came before any reptiles.
Active muscles demand huge amounts of oxygen, and the circulatory system works hard to provide it. Blood carries oxygen to the muscles. When the body is at rest, blood carries nutrients to the muscles so that they can repair and rebuild themselves. Blood also carries away the waste products that hard-working muscles produce, back out through the lungs to be filtered.
so they Circulatory system xx muscular system :)
<span>The P-site of the ribosomes is the site of polypeptide elongation during translation of mRNA. Therefore, a drug that binds to this site ensures that there is no elongation hence, basically, the translation process is inhibited. The <span>growing bacteria cell will stop growing and die due to lack of structural and functional proteins to grow and perform its cellular processes respectively..</span></span>
Cytokinesis is the process wherein actual division of the cell, including the cell membrane and the cytoplasm, from the parent cell to two daughter cells. The correct answer in this question is "the metaphase plate is the beginning area for cytokinesis" as the metaphase plate dictates the midpoint of the cell. A cell with a cell wall (plant cell, for example) cannot perform cytokinesis with a cleavage furrow but with a cell plate. Phragmoplast only develops in plant cells. Lastly, cytokinesis only starts after telophase.
The food chain that would include an aphid include:
- Plant ---> Aphid ----> Birds
- Plant ---> Aphid ----> Spiders
- Plant ---> Aphid ----> Bat
<h3>What is a food chain?</h3>
A food chain is a chart that shows how food is transferred from producers to consumers.
Producers are plants as they are responsible for producing food from inorganic materials using the Sun's energy.
Consumers depend on plants and other organisms.
