When the Sun's energy moves through space, it reaches Earth's atmosphere and finally the surface. This radiant solar energy warms the atmosphere and becomes heat energy. This heat energy is transferred throughout the planet's systems in three ways: by radiation, conduction, and convection.

1. Anaphase. In <span>Anaphase the sister chromatids separate from each other to the opposite sides of the cells.

2. </span>Chromosomes would not separate into two nuclei. <span>Mitosis is a process cell division, where one cell divides into two identical cells.
</span>
3. Metaphase I. <span>Meiosis prophase I is the phase in which chromosomal crossing over occurs. The phase after prophase I is metaphase I.

4. </span>Its body cells would have 36 chromosomes, and its gametes would have 18 chromosomes. <span>In the gametes, there are half of the number of chromosomes present in the body cell.

5. </span><span>A species has to adjust rapidly to a changing environment. To adjust to the environment, crossing over is necessary, and it does not occur in mitosis, but meiosis.

6. 50 percent. 
Parents:          Yy      x     yy
Offspring:    Yy    Yy    yy   yy
50 % is Yy  and 50% is yy.

7. </span><span>One parent had white eyes and the other was heterozygous for eye color. The ratio in the offspring is 50-50. The only possibility is the following:
Parents:       Rr     x     rr
Offspring   Rr    Rr   Rr   Rr

8. </span><span>Their fur will be a mixture of red and white hairs. The offspring will be heterozygous. They will have alleles for both red and white hairs and both will be expressed.
</span>
9. Not enough information.

10. <span>Both of the parents' genotype must have been Pp. The genotype of the white plant is pp since it is recessive:
Parents:        Pp     x     Pp
Offspring:   PP   Pp   Pp   pp
One of the four is white.</span>

The effect of cholesterol on membrane fluidity at physiological temperatures is to Choose one: A. prevent lateral movement of ph
kobusy [5.1K]

Answer:

The correct answer is  D. maintain membrane fluidity through its disruption of fatty acid packing.

Explanation:

<u>Cholesterol</u> is a steroid lipid and is a constituent of biological membranes. It regulates the <em>fluidity</em> of the membrane (so, option C is not correct). Since cell membranes are composed of another type of lipids, the phospholipids, which form a bilayer, cholesterol distributes between the phospholipid tails and avoids these molecules pack each other forming rigid clusters. Thus, the option which better explains the effect is <em>D. maintain membrane fluidity through its disruption of fatty acid packing.</em>

icang [17]
You did not included your list of selections.  Some general properties ascribed to DNA are storage and expression of information and variables through mutations.  Replication, Transcription, Translation and Mutagenesis are the major functions of DNA in a cell.  DNA nucleotides contain deoxyribose.  DNA is double-stranded in the conservative mode, the original double Helix remains a complete unit and the new DNA double Helix is produced as a single unit.  In the double=stranded DNA, Hydrogen bonds hold one complimentary strand to the other.  

Hope this helps, I love Science.

Why do we have 4 chambered heart
My name is Ann [436]

。☆✼★ ━━━━━━━━━━━━━━  ☾  ━━━━━━━━━━━━━━ ★✼☆。

- To keep our oxygenated blood and our deoxygenated blood separate.

Having 4 chambers allows these 2 types of blood to reach their appropriate destination without getting mixed up.

Have A Nice Day ❤
