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

Explain the processes of venous return in the abdomen. do not just list them! why must the veins employ these methods?
vodka [1.7K]

Answer:

Venous return (VR) is the flow of blood back to the heart.  

Venous return to the right atrium is the most important factor determining cardiac output, provided both ventricles and the pulmonary circulation are normal.

Explanation:

Venous return refers to the flow of blood from the periphery back to the right atrium, and except for periods of a few seconds, it is equal to cardiac output.

Venous return is facilitated by a number of factors, including inspiration, increased total blood volume, increased venomotor tone, the cardiac suction effect, the presence of venous valves and the skeletal muscle pump.

Contraction of the skeletal muscles surrounding veins increases the pressure within the veins, pushing open the proximal valve and forcing blood toward the heart. For example, when calf muscles contract during exercise, blood is forced toward the heart, thus increasing venous return.
