When environmental conditions are unfavorable, why is it an advantage for green algae to reproduce sexually? a. They are multicellular when conditions are unfavorable, which favors sexual reproduction.
b. Sexual reproduction produces larger numbers of offspring in less time.
c. Sexual reproduction produces offspring that have greater genetic variety and durable zygotes that can help green algae species survive unfavorable conditions.
d. Sexual reproduction produces multicellular algae instead of unicellular algae. Multicellular algae are better able to survive harsh conditions.

Answers

Answer 1
Answer: d. Sexual reproduction produces offspring that have a greater genetic variety and durable zygotes that can help green algae species survive unfavourable conditions.

in human cells 2N = 46. how many chromosomes would you expect to find in a sperm cell? in am egg cell? in a white blood cell? Explain

Answers

Answer:

There will be 23 chromosomes in a sperm cell, 23 chromosomes in an egg cell, and 46 chromosomes in a white blood cell

Explanation:

Human cells are diploid in number i.e they exists in two basic sets (2N =46, where N is 23). So, cells of human body such as blood cells like white blood cells have two basic sets of chromosomes i.e 46 chromosomes, since they are produced by mitosis.

On the other hand, cells of humans involved in sexual reproduction such as the gametes (sperm and egg) have only one set of chromosomes since they are produced by meiosis - so they are haploid (N =23).

Answer:

Sperm=23

Egg cell=23

White blood cell=46

Explanation:

During cell division Meiosis produce haploid number of gametic chromosome 23.

The somatic cell contains 46 chromosome i.e diploid chromosome number. During cell division in meiosis gametes cells contains haploid number-23 chromosome which is half of the somatic cell chromosome.

During conjugation, haploid chromosome is donated by each parent to give a diploid organism with 46 chromosome number.

White blood cell contains 46 chromosome because it doesn't undergo cell division it is a somatic cell.

In the context of the difference threshold, _____ is the principle that two stimuli must differ by a constant proportion to be perceived as different.

Answers

Answer:

The answer is Weber's law

Explanation:

In the context of the difference threshold, Weber's law is the principle that two stimuli must differ by a constant proportion to be perceived as different.

- Weber's Law states that "for the difference to be perceptible, two stimuli must differ by a constant proportion, not a constant amount".

Which biome would you Most likely find permafrost

Answers

Answer:

The tundra biome

Explanation:

The permafrost are defined as the thick subsurface soil inter-mixed with rocks, that remains frozen for more than a year. They are commonly found in the high latitude areas, specially in and around the polar regions.

The tundra biome is mainly characterized by the presence of permafrost layers. This biome occupies the polar region, where there is less amount of trees and the temperature remains relatively very cold through out the year, favoring the formation of permafrost layers in it.

Every species exhibits variations based on various genes being activated at various times. An example with humans can be eye color or hair color. What species means is that all members of a species can procreate with healthy, capable of procreating progeny, but anything else is just a variation.
