Sort the descriptions based on whether they are related to asexual reproduction or sexual reproduction
miss Akunina [59]

Answer:

Sexual Reproduction:

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

Asexual Reproduction:

  1. Creates genetically identical offspring.
  2. Organism doesn't have to waste energy to find a mate.
  3. 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:
  1. Binary fission
  2. Fragmentation
  3. Budding
  4. Parthenogenesis

Effectus [21]
<h2>Answer:</h2>

When the crossing over results in both mutant alleles on one chromosome and the other chromosome will be mutation free.

<h3>Explanation:</h3>

During the meiosis chromosomes are present in homologous form in a pair.

They exchange their genetic material with each other. This exchange is random and usually genetic material on the ends/telomere changes with the homologous chromosome.

In given condition the exchange is in such manner that the mutant allel of one chromosome shifts to other during crossing over. While other chromosome also contains its own mutant allele and does not exchange it during crossing over.

The crash risk potential is approximately _______ times greater after dark than during the daylight hours.
ankoles [38]
In driving a vehicle, the crash risk potential is approximately 4 times greater after dark than during the daylight hours according to the US Department of Transportation, Federal Highway Administration. This is due to the reduced visibility of the streets at night as well as direct bright light shining to drivers' eyes by the vehicles going the opposite way. This is also increased when there is heavy rain which further reduces the visibility.
