Biology
1 answer:
meriva3 years ago
6 0

Answer:

The correct answer is option D.

Explanation:

The plasma membrane is the outer membrane of the cell that surrounds the cytoplasm and other cell organelles found in it. The plasma membrane acts as a barrier between the outside of the cell and the inner side of the cell. This membrane has a lipid bilayer and has a hydrophilic head and hydrophobic tail.

Phospholipids and many membrane proteins are moves in lateral or transverse motion, movement of lipids and proteins called lateral diffusion.

Thus, the correct answer is option D.

Prokaryotes divide by binary fission, a form of asexual reproduction in which
evablogger [386]

Prokaryotes divide by binary fission, a form of asexual reproduction in which a cell divides into two cells with identical genetic information.

Explanation:

Binary fission and mitosis can be viewed as the same principle of  asexual reproduction to give out two identical cells. However, the major difference between the two is that binary fission is to prokaryotes and mitosis is to eukaryotes. Remember that prokaryotes do not have a true nucleus (they have a nucleoid) hence binary fission does not involve the dividing of the nucleus. Mitosis does.

Sexual reproduction is responsible for creating variation in offspring especially due to the process of meiosis in gamete development and subsequent fertilization of two gametes from different parents.

Which statement is true regarding monocytes
vodka [1.7K]

Answer: <u>Option C, they digest pathogens</u>

Explanation: Monocytes are involved in the process of digesting pathogens and infected cells, termed as phagocytosis.

Monocytes don't produce antibodies, only B cells can produce antibodies. So, option A and D are incorrect. Also they appear colorless when observed under the microscope. They don't appear granular, so option B is also incorrect.

Explain how fertilization occurs
alex41 [277]
<span>I'm assuming this in plants.

Brief-ish answer:

"Fertilization in plants occurs when pollen grains are transported from anthers to stigma. When ripe pollen from an anther catches on the stigma of the same kind of flower, each pollen grain sends out a small thread-like tube."

Here's a fuller answer:

"</span>Fertilization occurs after pollination, when pollen grains land on the stigma of a flower of the same species. During this time, a series of events take place leading to the formation of seeds. A pollen grain on the stigma develops a tiny tube that runs down the style of the ovary. The pollen tube contains a male gamete which meets the female gamete in the ovule. Fertilization occurs when the two gametes combine and their chromosomes join. The resulting product is a normal complement of chromosomes, with some from either parent flower. The fertilized ovule forms a seed, which consists of a food reservoir and an embryo that later develops into a new plant. In gymnosperms (conifers) male gametes are enclosed in pollen grains and are transmitted by wind or insects to the female reproductive organs. Fertilization in angiosperms (flowering plants) occurs when insects or other animals transport the pollen to the female reproductive organ (pistil).<span>
</span><span>Fertilization is the fusion of gametes to launch the development of a new individual organism. In animals, the process entails the combination of ovum with a sperm, leading to the development of an embryo. Fertilization in plants occurs when haploid gametes meet to create a diploid zygote, which eventually forms an embryo.</span><span>"
