Which description is correct for both oogenesis and spermatogenesis?
The cells have 46 chromosomes until meiosis II is completed.
After meiosis I, the cells have 23 chromosomes.
Part of meiosis I is completed before birth.
The entire process takes about 70 days.

Answers

Answer 1

Answer:

After Meiosis I, the cells have 23 chromosomes

Explanation:

It is B

Answer 2

In meiosis there is a reductive phase (meiosis I) and the not reductive phase (meiosis II). Option B). After meiosis I, the cells have 23 chromosomes.

What is meiosis?

Meiosis is a process by which, from a diploid germ cell (2n), four haploid cells (n) -the gametes, sperm and egg cells- are produced. This is the gametogenesis process.

Each daughter cell has half of the chromosomes of the original one.

There are two phases in meiosis:

the first one in which occurs a chromosome's reduction division, and the second one where the cell suffers a new division, but this one is not a reductive one.

So, if the germ cell has 46 chromosomes, after meiosis I each new cell will have 23 chromosomes, because meiosis I is the reductive phase.

Option B is correct.

For the proteins you researched, how does the structure help the protein perform its function?

Answers

Answer: Protein structure depends on its amino acid sequence and local, low-energy chemical bonds between atoms in both the polypeptide backbone and in amino acid side chains. Protein structure plays a key role in its function; if a protein loses its shape at any structural level, it may no longer be functional.

Hope this helps.... Stay safe and have a Merry Christmas!!!!!!! :D

The relationship between the structure and function of proteins is complex. The way a protein interacts with other molecules in the cell depends on the precise arrangement of amino acids and the resulting three-dimensional form.

For example, the structure of a protein's active site enables it to bind to particular substrates and act as an enzyme by catalyzing chemical reactions. Signals can be transmitted by receptor proteins because of their binding sites, which fit into particular molecules like keys to a lock. Collagen and other structural proteins form the fibrous network that gives strength and support to tissues.

Molecules can travel across membranes more easily thanks to unique channels or binding sites on transport proteins. A protein's stability, folding and ability to carry out its intended function all depend on its overall structure.

Answer:

Estuaries is a water body where freshwater from rivers and streams combines with salt water that is coming from the ocean.

Explanation:

Estuaries is a type of water body that is partially enclosed present at the coastal side where freshwater from rivers and streams combines with salt water that is coming from the ocean. Shallow estuary waters create unique habitats for organisms living there because the presence of brackish water refers to the mixture of fresh water draining from the land and salty seawater. The salinity in water change as you move from inland areas out towards the ocean because the water of inland has less salt in it while water of ocean has huge amount of salt present in it so when we move from inland to the ocean salt concentration increases in it. estuaries provide protection for inland areas by filtering pollutants, prevent shoreline erosion, flooding and storm.
