Answer:

are not dependent on water for reproduction

Explanation:

In terms of seed production, plants are generally divided into 2:

  • Seedless plants
  • Seed producing plants

Seeds serve as structure for propagation and contains an embryo that is usually nourished and protected by the seed coat. The embryo results from fertilization of the ovule by the pollen grain, a process that takes place after pollination. The entire process is independent of water.

Seedless plants produce spores instead. These spores can be sexual or asexual. Sexual reproduction in seedless plants requires that the male gametes (sperms) swim to meet the female gametes (egg). Consequently,  water is necessary for the motile male gametes and that is why most seedless plants grow is aquatic or moist areas.

<em>Hence, unlike seedless plants, seed plants are not dependent on water for reproduction.</em>

Which best describes how waste is secreted in each system
Alex777 [14]

Answer:

The digestive system excretes a solid waste, and the excretory system excretes liquid waste.

Explanation:

The digestive system is the system of the body that breaks down food substances to enhance so that they can absorb them. But it also excretes solid indigestible substances. For excreating, they use the defecation process.

Excretory system, on the other hand, is a system in the body that removes homeostatic wastes from the body by using a process which is called excretion. Excretory includes organs such as liver, sweat glands, lungs. Among this, the liver plays a critical role in the secretion of homeostatic wastes in the form of fluids.

The excretory system collects and then filters excess water which is present in the body and then excretes it as a liquid waste either from the liver, kidneys, or sweat glands on the skin through sweating.

kobusy [5.1K]

Answer:

Human males much more likely than human females to inherit the recessive condition hemophilia because it follows X-linked recessive pattern.

Explanation:

Actually hemophilia is an X-linked recessive disorder i-e the defective genes are located on the X chromosome (sex chromosome) and are transmitted through it. As males have only one X chromosome (inherited from mother), one altered copy of the gene in every cell cause this disease.On the other hand females have 2 X chromosomes thus this disease is rare in females.
