Answer:

Option (3).

Explanation:

Eukaryotes have well defined the cell organelles that are bound by the membrane. Endomembarne system divides the cell organelle into the structural and functional compartment of the cell.

The endomembrane system is important for the protein synthesis, process and transport of the protein. The proteins that are secreted into the cell remain bound to the membrane of the endomembrane system.

Thus, the answer is option (3).

The correct answer is: Proteins that will be secreted from the cell are likely to be found in closed spaces bounded by membranes of the endomembrane system.

The endomembrane system is a group of organelles and their surrounding membranes in eukaryotic cells (prokaryotic cell doesn’t have membrane enveloped organelles) that works together in order to modify, package, and transport lipids and proteins. It includes nucleus with its nuclear envelope, lysosomes, the endoplasmic reticulum (smooth and rough), Golgi apparatus but also plasma membrane around the whole cell. The endomembrane system does not include mitochondria, chloroplasts, or peroxisomes.

Harman [31]

Answer: We can ignore both A and B as they are not actions at all

And C is ruled out because it isn't Marlene's action it's Tami's therefore the answer is D. D also develops Marlene's character as it shows her anxiety and her caring nature towards her cat.

A 25-year-old woman who recently underwent genetic testing has just learned that she is heterozygous dominant for Huntington dis

laila [671]

Answer:

The odd is zero.

Explanation:

Assuming the Huntington disease allele is represent by b. Nomal allele will be B which is the alternate form.

The genotype of the 25 years old woman will be Bb, since she heterozygote.

The genotype of the husband will be BB, since he's free from the trait.

Crossing both genotypes:

Bb x BB = BB, BB, Bb and Bb.

The genotypes of the offspring will be either BB or Bb. They either free from the trait or heterozygote.

<em>Hence, the odds that the couple will have a child with the disorder is 0. They can only produce heterozygotes or totally normal children.</em>

____________________ is the process by which a cell makes a copy of the DNA in its nucleus.

dlinn [17]

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2 />

$\huge\boxed{Option A}$

<h2>_____________________________________</h2><h2>REPLICATION</h2><h3>---------------------------------------------------------------------------------------------</h3><h3>Definition:</h3>

DNA replication is the process by which a double-stranded molecule of a DNA is replicated(copied) to produce two morphologically and chemically identical DNA molecules.

<h3>__________________________________________________</h3><h3>Why is it Important:</h3>

Replication is a very important process for the living organism, because in a cell division, the two new daughter cells are produced which must contain the same genetic information or the DNA just like the parent cell. It cant be less or more than the parent cell.

<h3>__________________________________________________</h3><h3>Steps of Replication:</h3>

Replication occurs in three major steps,

1- the opening of the double helix and separation of the DNA strands,

2- the priming of the template strand.

3- the assembly of the new DNA segment.
