Lerok [7]

Transposable elements are DNA sequences that contain numerous point mutations. Thus, option "4" is correct.

<h3>What are Transposable elements?</h3>

Transposable elements are fragments of DNA that have the ability to jump from one part of the genome to another. While most of the DNA is always in the same place surrounded by the same neighbouring pieces of DNA, mobile elements move from one place to another causing many changes or mutations.

When a transposon moves through the genome, it can insert into a vital gene, disrupting its function, or into a location near vital genes, causing erroneous activation or inactivation.

On the other hand, there can be chromosomal rearrangements due to transposons of the same family with complementary sequences that are separated in the genome and that by sequence homology match.

This can lead to ectopic recombination. Large-scale rearrangements induced by mobile elements are considered a particular class of recombination events that influence genomic plasticity.

Thus, option "4" is correct.

timama [110]
For every experiment conducted by scientists, there are usually independent variables and dependent variable. The independent variable is that parameter whose variation does not depend on that of another variable while the dependent variable is the one whose variation depends on the independent variable. 
In the question given above, the independent variable is the fertilizer used while the dependent variable is the growth of the plant.
Conventionally, independent variable are normally placed on the X axis of the graph while the dependent variable goes on the Y axis. Thus, the quantity of fertilizer used will be plotted on the X axis [Horizontal line] while the increase in the plant growth will be plotted on the Y axis [Vertical line].

What will happen if the glomerular filtration rate is too low?
MAVERICK [17]

Answer:

c. Wastes will build up in the blood  

Explanation:

Glomerular filtration rate is a measure of renal function that can be calculated from a simple blood test that measures blood creatinine levels and takes into account age, ethnicity, gender and other factors. Through the glomerular filtration rate, your doctor can determine the stage of kidney disease and plan treatment. The lower the GFR, the more severe the renal failure.

Since kidney failure is the slow loss of kidney function, its main function is to remove waste and excess water from the body. We can conclude that if the glomerular filtration rate is too low, debris will accumulate in the blood.
