Answer:

Continuous cultivation of crops in soil leads to the depletion of certain nutrients.
If these nutrients are not replenished, soil becomes sterile and unfit for cultivation.

Answer:

we need to replenish nutrients into the soil because all nutrients that soil has used up by plants during their growth. if these nutrients are not replenished, soil become sterile and unfit for cultivation.

A landslide has isolated a part of the cicada population from the main population. After a few generations, the new generations

umka2103 [35]

The bottleneck effect is the cause of the sudden shift in the genetic information of the population. Due to the landslide, suddenly high number of the members of the main population died, and this caused genetic drift for reducing the variation in the existing generation, which is now widely different from the original one.

Sometimes a bee performs a maneuver, known as the “wiggle dance” in front of another bee. what is the purpose of the maneuver?

irina [24]

By performing this dance, successful foragers can share, with other members of the colony, information about the direction and distance to patches of flowers yielding nectar and pollen, to water sources, or to new nest-site locations.

Sort the descriptions based on whether they are related to asexual reproduction or sexual reproduction

miss Akunina [59]

Answer:

Sexual Reproduction:

Creates genetically unique offspring.
Organism needs time to reach adulthood and to reproduce.
Requires the contribution of two parents.

Asexual Reproduction:

Creates genetically identical offspring.
Organism doesn't have to waste energy to find a mate.
Requires the contribution of a single parent.

Explanation:

Sexual Reproduction:

Sexual reproduction involves the fusion of a male and female gamete. A gamete is a haploid cell that contains half of the chromosomes as in the parent cell. This process is called fertilization and it results in the formation of a zygote, a diploid cell that develops into an embryo and ultimately an individual.

Sexual reproduction involves two parents, each of which contributes one set of chromosomes (23) to the offspring.

Asexual Reproduction:

Asexual reproduction produces an exact copy of one single parent. Offspring produced through asexual reproduction do not possess genetic variation.

Asexual reproduction occurs through four processes:

Binary fission
Fragmentation
Budding
Parthenogenesis
