<h3><u>Answer;</u></h3>
The permeability of the membrane
<h3><u>Explanation</u>;</h3>
- The fluidity and the permeability of cell membrane must be maintained within a certain range for the cell to function properly.
- The permeability of cell membrane depends on a number of factors, among them is the degree of saturation of fatty acids tails making up phospholipids.
- Phospholipid tails can be saturated or unsaturated. Saturated tails have no double bonds and as a result have straight, unkinked tails, while unsaturated tails have double bonds and, as a result, have crooked, kinked tails.
- Interactions between tails are maximized in the case of saturated tails, thus decreasing membrane fluidity and permeability, while unsaturated tails increases membrane fluidity.
Answer:
Carbon, Hydrogen, Oxygen, Nitrogen, and Phosphorus
Explanation:
Proteins are mainly made up of amino acids. The basic structure of amino acids is that they have a carboxylic group, amino group and side chain. The carboxylic group is mainly Carbon, Hydrogen and Oxygen. The amino group is mainly Nitrogen and Hydrogen. The side chains are unique per amino acid having different elements including Phosphorus.
The Catskills are considered a dissected plateau as at one point it was a complete plain level land that due to seismic activity got uplifted and then eroded over time, otherwise the entire land piece is part of a much larger plateau.
The answer would be: accumulate the melanin granules on their superficial portion, forming a UV-blocking pigment layer
<span>The number of melanocyte cells is not much compared to keratinocytes. That is why melanocytes secrete dark melanin granules that will be spread into keratinocytes, not to itself.
The nutrient should be provided by the blood vessels of dermis skin. There should be no problem with pH or temperature either.</span>
"I understand how this can be frustrating, but rest assured this does not place your child at a disadvantage academically."
"All of these expensive toys that are advertised and purchased by some people are not necessary for preschoolers. Simple toys like chalk and Legos are great."
"Do you play with your child and provide means of play through things like dolls, puzzles, crayons, and Play-Doh? These are the types of toys suggested for preschoolers."
<span>Expensive and elaborate toys do not place a child at an academic or developmental advantage. Simple toys that require interactive rather than passive play, and that may include the involvement of the parent, are recommended to foster development.</span>
