Answer:

Homology in bat wings, alligator leg, and a human arm represents their divergent evolution from common ancestor.

Explanation:

Homologous organs share a common basic structure but are adapted to perform different functions according to the need of organisms. Wings of bats (flying mammal), leg of alligator (reptile) and human (terrestrial mammal) arm share common basic developmental plan but are adapted to serve in flight, movement and holding things respectively.

Presence of homologous organs in these organisms from different group represents their evolution from a common ancestor. This means that bats, human, and alligators should have a common ancestor. Divergent evolution of the descends from the common ancestor must have given rise to homologous structures.

Which group of non-prokaryotic organisms studied in microbiology typically have two life cycle stages: trophozoite and cyst?
Mama L [17]

Non-prokaryotic organisms typically have two life cycle stages: trophozoite and cyst is Protozoa.

<h3>What is Protozoa?</h3>
  • Protozoa is a group of single celled, non- prokaryotic organisms.
  • These may either be free living or parasitic in nature.
  • These are heterotrophs and reproduce asexually by binary fission.
  • The Protozoa consists of many unrelated or loosely related organisms.
  • They are divided into four major groups:  Sarcodina, Flagellates, Ciliates and Sporozoans..
  • Some protozoa consist of two phases in their life cycle: proliferative stage (trophozoites) and resting stage (cysts).
  • Trophozoites consists of the proliferative stage in which the protozoa divides and reproduces.
  • The resting cyst form helps the protozoa to survive harsh environmental conditions like harmful chemicals, extreme temperature and nutrient and water deficiency.

Which of the following statements about plant cell walls is true?
Leya [2.2K]

Answer:

<h2>A </h2>

Explanation:

1. The cell is present in some type of cells. It is found in plants and bacteria and some others. It is present or found outside the plasma membrane.

2. The functions of cell wall are that it provides tensile strength and protection to the cell against many type of stress. It also plays very important role in many others protections for the cell. There are two layer, named as primary cell wall and secondary cell wall.

3. Composition of Plant cell walls is that they are primarily made of cellulose. Cellulose fibers are linear long polymers of around  100 molecules  of glucose. These fibers cluster into bundles, known as  or called microfibrils. In plants the microtubule cytoskeleton are present, and there function is that they directs the orientation of cell wall as  in which orientation cellulose is deposited in the cell wall.

mariarad [96]

Answer:

Mendel disproved the blending theory of genetics when he cross pollinated tall and short pea plants and the offspring were either tall or short, not medium like the blending theory of genetics suggests.
