galina1969 [7]4 years ago
5 0

The correct answer is E. A cell

Explanation:

The cell is the smallest unit of life that exists and that constitutes all living organisms and body tissues including unicellular and multicellular organisms. Due to this, cells are considered as the fundamental unit of life as even the smallest and simplest living organisms are made of cells or at least made of one cell.

Cells are commonly made up of three main parts: the cell membrane which surrounds the cell and controls the substances that enter and leave it; the nucleus which is the structure within the cell that contains the nucleolus and most of the cell's DNA; and the cytoplasm that is the fluid inside the cell that contains other tiny cell particles with specific functions, such as the Golgi apparatus, mitochondria, and the endoplasmic reticulum. This applies to all cells except to prokaryotic cells because these do not contain a nucleus but a chromosome in the middle of the cell.

Suppose a human blood cell containing a 0.9 percent solute concentration were put into a container of 0 percent solute solution
Vladimir [108]

Answer and explanation:

If a human blood cell with a 0.9% solute concentration were to be put into a container of 0% solute solution, the cell would get BIGGER.

<u>The cell contains a </u><u>more concentrated solution</u><u> than the solution in the container</u>. The difference in concentration would produce an <em>osmotic gradient</em> that would cause water from the container to get inside the cell to even the concentrations - this is going to make the cell much bigger because the entering water would bloat the cell.

In this example, the solution in the container is hypotonic in relation to the cell, while the solution inside the cell is hypertonic in relation to the solution in the container. This is why the water will be moving from outside of the cell to the inside of the cell.

If all 5' and 3' splice sites were always used to process the pre-mRNA into mRNA, how many possible distinct mRNA sequences woul
lord [1]

The question lacks the diagram. The diagram has been attached below.

Answer:

1.

Explanation:

Exons may be defined as the coding region of the RNA whereas introns are the non coding region of the RNA. The introns must be removed out from the RNA to makes it functional molecule.

The splicing of the given molecule results in the formation of single mRNA. The 1 splicing of the introns remove intron A whereas the second splicing results in the removal of intron B. The functional mRNA consists of the mRNA with exon 1,2 and 3.

Thus, the answer is 1.

How is laying eggs on land an evolutionary advantage for sea turtles and capelin
gregori [183]

1. Laying eggs on land reduces the chances of the eggs being predated on by predators in the seas and oceans.  

2. Temperatures are critical in the development of the yolk into an embryo and full turtle. Temperatures even determine the sex of the developing turtles. Land heats up more than water hence promotes faster development hence increases the survival of the offsprings.
