Answer:
B
Explanation:
Amino acids fold to form the protein and give it its functionality. Different orders of amino acids fold differently and make a different shape. The shape of the protein defines its function. The function will vary wildly
Homologous evolution means divergent evolution.
it is a type of evolution in which different species have common ancestor. for example if we take members of one species and put them in different environments then it is observed that there is some changes in the species according to environment
analogues evolution means convergent evolution
1. blood vessels dilate
2. there is an aggregation of platelets (blood clots)
3. fibroblasts make collagen (healing agent under the skin)
4. neutrophilis consume the bacteria
5. macrophages remove the damaged tissue
6. the wound closes
hope that is right good luck
Mesozoic, the era contained both large reptiles and small birds/mammals. It's interesting, coming from an evolutionary biology.
Hope this helped!
Answer:
The correct answer is The cells do not have proper receptor.
Explanation:
During paracrine signaling a signaling molecules are generated from one cell.The generated signaling molecule then binds to the receptor of neighboring cell to carry specific signal from donor cell to the acceptor cell.
But the signaling molecules will not bind to the cell that is producing it because that producing cell do not contain proper receptor to bind that signaling molecule.
The binding of signaling molecule to the receptor of its producing cell occur during autocrine signaling.
