Answer:
Because natural selection selects for it. Thus it persists.
Explanation:
You have to understand heterozygote advantage. Basically, it's where heterozygotes have an advantage over homozygotes. In the case of sickle cell disease, heterozygotes have an advantage, and natural selection favors whatever is advantageous. Thus, because heterozygotes each have one recessive sickle-cell allele, as natural selection favors the heterozygotes, the recessive sickle-cell allele persists and remains in the gene pool.
The answer I came up with is Echinoderms and Chordates.
Happy studying!
Answer:
Cofilin binds to older actin filaments
Explanation:
Microfilaments (also called actin filaments) are a class of protein filament common to all eukaryotic cells, which consist of two strands of subunits of the protein actin. Microfilaments form part of the cell's cytoskeleton and interact with the protein myosin in order to allow the movement of the cell. Within the cell, actin may show two different forms: monomeric G-actin and polymeric F-actin filaments. Microfilaments provide shape to the cell because these filaments can depolymerize (disassemble) and polymerize (assembly) quickly, thereby allowing the cell to change its shape. During the polymerization process, the ATP that is bound to G-actin is hydrolyzed to ADP, which is bound to F-actin. ATP-actin subunits are present at the barbed ends of the filaments, and cleavage of the ATP molecules produces highly stable filaments bound to ADP. In consequence, it is expected that cofilin binds preferentially to highly stable (older) filaments ADP-actin filaments instead of ATP-actin filaments.
The line from "Samjay's Dream" that best shows his wish is that perhaps he would explain more about his goal and how he wouldn't leave his learned values behind.
<h3 /><h3>What is the difference between Samjay and his parents?</h3>
The way of socialization of both is a determining factor for the difference in the mentality of Samjay and his parents, whose knowledge and values are different.
Therefore, the conflict between them lies in the difference in mentality and values learned, and it is essential that Samjay develop self-knowledge for a clearer understanding of his desires and needs.
So, the correct answer is D.

The hypodermis (subcutaneous tissue) is the innermost layer of skin in your body. The dermis is the middle layer. The epidermis is the outermost layer.
<h3>What does the subcutaneous layer consist of?</h3>
Subcutaneous tissue is the deepest layer of your skin. It's made up mostly of fat cells and connective tissue. The majority of your body fat is stored here. The subcutaneous layer acts as a layer of insulation to protect your internal organs and muscles from shock and changes in temperature.
<h3>What is not found in dermis?</h3>
The answer is C fat cells. So the dermis is between the epidermis and the subcutaneous tissues.
