Scientists have isolated the gene that produces the bioluminescence protein and inserted the gene into the embryos of tetra fish. This results in tetra fish that produce a green glow.
How, support your answer?Tetra fish is a type or an example Glofish that has undergone genetic modifications whereby the gene in jelly fish that produces the green fluorescent protein (GFP) was extracted and inserted into the embryos of the tetra fish thereby causing them to glow or fluoresce in the presence of Ultraviolet light or natural light.
The genetically modified tetra fish passes this fluorescent gene from one generation to another.
Thus, The aim of this genetic modification in tetra fish was to be able to detect water pollution in the sea using the glow of the tetra fish.

Read the article to learn more about the disorders that can occur when there is an irregular number of chromosomes. human chromosomal disorders explain how nondisjunction can lead to aneuploidies.
The formation of the zygote with an abnormal number of the chromosomes is called aneuploidy.
What are the chromosomes?We know that the process of reproduction in organisms would involve the passage of the hereditary facts that can be found in the organisms that are under study. This was the focus of the laws that were put forward by Gregor Mendel. He did say that the factors that do control the inhertiance of the organisms are what we call the genes today.
Let us note that the genes that can be found in the organims as we know them are contained in the chromosomes. The chromosomes are also able to be divided as the cell is being divided. In the stages of the cell division, the process by which the chromosomes are separated is called the disjunction.
There are cases where the chromosomes do not separate and this is what we call the nondisjunction of the chromosomes.
Since the chromosomes do not separate accordingly due to nondisjunction, there would be an unusual number of chromosomes and this is called aneuploidy.

What of the following will occur after a fire burns down 100 acres of a forest?
Question 2 options:
The forest cannot recover without human intervention
Primary Succession
Secondary Succession
Adaptive Radiation
Secondary Succession will occur after a fire burns down 100 acres of a forest. thus option C is correct.
What is secondary succession?When a disturbance does not completely remove all life and nutrients from the environment, secondary succession occurs.
Despite the fact that fire, flooding, and other disturbances can devastate a landscape, drive away many plants and animals, and reset the biological community to an earlier stage, the habitat remains alive because the soil stores nutrients and seeds that were laid down before to the disturbance.
Buried seeds can sprout soon after the disruption has passed, and some may have a better chance because of less competition and less shading. Some animals may have evolved to deal with a particular disturbance on a regular basis.

What is the slope of the line? please help.
Answer:
The slope is [tex]\frac{4}{3}[/tex].
Explanation:
Slope is [tex]\frac{y}{x}[/tex], and to find it we need to look for where the line directly ends on the corner of the graph square. One occurs at (3,4), but the reason the slope is 4/3 and not 3/4 is because it is y over x. The y coordinate lines up at 4 and the x lines up at 3 getting you your answer of [tex]\frac{4}{3}[/tex].

If a scientist is conducting an experiment about obesity and asks a group of people to stop eating saturated fat, that group of people is called:
the control group.
the experimental group.
the qualitative group.
the quantitative group
Among the groups involved in an experiment, the experimental group is the one influenced by the independent variable -treatment-. Option B. Experimental group.
What is the experimental group?
During an experiment the researcher compares at least two groups: a control group and an experimental group.
Both of them are composed of individuals coming from the same population, so they are identical in all aspects except for the independent variables.
The experimental group is the one that receives the treatment. The researcher voluntarily changes the values of the independent variable to observe how it affects the individuals subjected. There can be several experimental groups.
In the exposed example, the independent variable is eating saturated fat.
Among all the individuals involved in the experiment, the group that stops eating saturated fat is the experimental group.
The researcher eliminates saturated fat from the diet of the experimental group to observe how it affects the weight of individuals.
