Which two processes that occur during the formation of gametes contribute to increasing diversity within a populations gene pool
yanalaym [24]

Answer:

1) Crossing over

2) Independent assortment.

Explanation:

Gametes are formed resulting from the process of meiosis where the gametes get half of the original number of chromosomes. One phenomenon that happens during the prophase 1 of Meiosis and leads to the genetic diversification is crossing over. In this process , Here, homologous chromosomes pair up and exchange information present on genes from one another. When information is exchanged, it leads to the diversity of genetic data.

The second way of increasing genetic diversity is independent assortment that takes place during metaphase 1. In this process chromosomes from both father and mother cells align on equatorial plate of the cell in an independent manner. This means that some gamete can have 1 of many different chromosomal combinations.

This reshuffling of chromosomes during independent assortment enhances the genetic diversity of any organism and this also explains why kids of same parents can look or behave very different.

Hope it help!

What kind of channels are located in the input region?
tamaranim1 [39]

Answer:

The correct answer is option B ( ligand gated channels opened by neurotransmitter molecules).

Explanation:

Input region or postsynaptic region or dendrite is the site of neuron cell which receives the impulse from the pre-synaptic neuron at the synaptic junction.

The cell membrane of the dendrite is embedded with ligand-gated channels which opens up in response to the ligand (neurotransmitters) produced by the neurotransmitter vesicle of axon or output region of neuron.

The neuromuscular junction is such a case where acetylcholine receptors present in the dendrite opens in the presence of acetylcholine.

Thus, option B ( ligand-gated channels opened by neurotransmitter molecules) is the correct option.

10. Define the following terms:<br>a. Nucleoid-<br>b. Mesosomes -<br>d. Capsid -<br>e. Plasmalemma-​
malfutka [58]

Answer:

Alright, sure thing.

Explanation:

a. Nucleoid- The nucleoid (meaning nucleus-like) is an irregularly-shaped region within the cell of a prokaryote that contains all or most of the genetic material.

b. Mesosomes- Mesosomes or chondrioids are folded invaginations in the plasma membrane of bacteria that are produced by the chemical fixation techniques used to prepare samples for electron microscopy.

d. Capsid- A capsid is the protein shell of a virus, enclosing its genetic material.

e. Plasmalemma-​ The cell membrane is a biological membrane that separates the interior of all cells from the outside environment which protects the cell from its environment.
