katen-ka-za [31]

Answer:

The correct answer will be- Meiosis I, anaphase I

Explanation:

Alleles are the variant alternative forms of a gene which determines the trait of an organism. The trait or phenotype is expressed only when the two alleles controlling a single trait on separate chromosomes are aligned in a complementary position.

During gamete formation, the alleles controlling a trait segregate independently of each other. This segregation of alleles takes place during Anaphase I of meiosis I. During anaphase, the sister chromatids are separated by the mitotic spindles so that the chromosomes can reach the opposite poles.

Thus, Meiosis I, anaphase I am the correct answer.

How do the unsaturated fatty acids in phospholipids affect the structure of cell membranes?
ludmilkaskok [199]

Unsaturated fatty acids are a component of the phospholipids in cell membranes and help maintain membrane fluidity. The Phospholipids contain a variety of unsaturated fatty acids, when compressed, the “kinks” in their tails push adjacent phospholipid molecules away, that helps in maintain fluidity in the membrane. Unsaturated fatty acids have at least one double bond, creating a "kink" in the chain, the absence of double bonds decreases fluidity, making the membrane very strong and stacked tightly.

The ratio of saturated and unsaturated fatty acids determines the fluidity in the membrane at a temperature, at appropriate temperatures the phospholipids have enough kinetic energy to overcome the intermolecular forces holding the membrane together, which increases membrane fluidity.
