What happens on the outer surface of a cell?

Biology
1 answer:
Papessa [141]3 years ago
5 0
<span>The outer surface of a cell is surrounded by the plasma membrane, which marks the boundary between the cellular content and the external medium. The plasma membrane is a continuous film made up of molecules of lipids, proteins, and carbohydrates. Lipids form a double layer and proteins are arranged in an irregular and asymmetric way between them. These components have mobility, which gives the membrane a high degree of fluidity. It acts as a semipermeable and selective barrier regulating the chemical composition of the cell.</span>

1.True or false? Gametogenesis is the same as meiosis?
Lostsunrise [7]

1. False. They are similar, though.

meiosis- A kind of cell division involving having the chromosome number. It is responsible for genetic recombination.

Gametogenesis- It's the process when gametes or germ cells are produced in an organism. They undergo meiosis to form gametes.

2. Spermatogenesis- happens in the testes of males. 4 gametes are produced. Spermatogenesis involves a metamorphosis stage called spermiogenesis. Spermatogenesis produces small, motile spermatozoa

Oogenesis- takes place in the ovary in a female. 1 gamete produced. in oogenesis there is no metamorphosis stage. In oogenesis the ovum is spherical, and isn't motile and is bigger with more food reserves and cytoplasm.

3. Because The one egg cell that results from meiosis contains most of the cytoplasm, nutrients, and organelles.

Atelectasis is caused by occupational exposure to coal dust.<br> a. true<br> b. false
Irina18 [472]
The statement is true. Atelectasis is the collapse or closure of a lung resulting in reduced or absent gas exchange. It may effect part or all of a lung. An airway blockage also can cause Atelectasis. A blockage may be due to a foreign object, a mucus plug, lung cancer, or a poorly placed breathing tube from a ventilator. When a blockage occurs, the air that's already in the air sacs is absorbed into the bloodstream.
