What is the meaning of the name restriction length polymorphism and where does it come from
The term "restriction fragment length polymorphism" (RFLP), which stands for individual changes (or variants) in DNA sequences at locations identified by restriction enzymes.
What causes restriction length polymorphism?Botstein et al. (1980) created restriction fragment length polymorphisms (RFLPs), which employ restriction enzymes to cleave the DNA molecule at particular locations known as restriction sites, producing various fragments with varied lengths.
What is RFLP, and what are some of its drawbacks?Restriction One technique for studying DNA used by forensic scientists is fragment length polymorphism (RFLP). The DNA strand is divided into pieces during this procedure by an enzyme. One restriction is that it struggles with dirt or mold.

Does protein for fur have more energy than collagen?
If so come up with a hypothesis as to why it takes more energy to form some proteins than others.
Yes, Does protein for fur have more energy than collagen. The hypothesis as to why it takes more energy to form some proteins than others is that doing more work requires more energy from your body, that results in increased calorie burn.
How much energy does whey protein provide?One of the most often utilized proteins is whey protein, which is ideal for daily use. It is easily digestible and includes all nine necessary amino acids. It can lower stress levels and increase energy.
Note that Fur proteins are widespread transcriptional controllers that were once thought to be solely responsible for maintaining iron homeostasis in most prokaryotes. They utilize ferrous iron as a co-regulator by binding to specific sequences (Fur boxes) found in the upstream promoter region of the iron sensitive genes (Fillat 2014).

A molecule that can be used as a molecular clock has a neutral mutation rate of one mutation per 5 million years. How many years ago did two species share a common ancestor, if the molecules found in these two species differ by a total of eight mutations?
1.5 million years
10 million years
40 million years
20 million years
20 million years ago two species share a common ancestor, if the molecules found in these two species differ by a total of eight mutations.
Neutral mutations play an major role in the phenomenon of evolution because they generally take place at a consistent rate over time.
Every time when a genome is passed from one generation to another , a small error is responsible for changing the base sequences. So the mutation rate in the genome copy is calculated by both the rate of error per copy and the number of copies made per unit time. Both of these factors may be impacted by species biology.

Speed can be determined by dividing the distance by the Displacement Time Velocity Density
The speed of a moving object can be determined by dividing the distance traveled by the time taken. The second option.
What is speed?Speed is the property of a moving body that is obtained by finding the ratio of the distance covered by the body and the time taken to cover the distance.
The speed of a moving object can be expressed mathematically as:
Speed = distance/time.
The SI unit of distance is meter while the SI unit of time is seconds. Thus, the unit of speed is meter per seconds, usually denoted as m/s. However, any other unit that is a derivative of meter per second can be used to qualify the speed of an object.
The speed of an object is a scalar quantity because it measures magnitude only. This is unlike vector quatities that has both magniture and direction.

After an experiment, Monica creates a graph that shows a direct linear relationship between the size of a fish and the amount of oxygen the fish uses. Describe this trend in terms of the amount of oxygen that a fish would use us as it grows from being very smart very large
Increase in the metabolic activities of the fish necessitated the increase in the consumption of oxygen hence the straight line graph.
What is an experiment?We know that when we carry out an experiment, the aim of the experiment is so that we can be able to deduce the nature of the relationship that is seen to exist between two variables. The variables are the independent and the dependent variables. The dependent variable is directly affected by the independent variable as it changes.
We are also told that what we have here is a straight line graph. This implies that the amount of oxygen that the fish was using was increasing as the age of the fish was increasing. This is what has accounted for the straight line graph.

D. water absorption from plants
Answer:
B.
Explanation:
Photosynthesis is basically plants using sunlight (or any light) to make 'food'.
Plants, algae, and cyanobacteria that contain chlorophyll engage in the most prevalent and important type of photosynthesis. These organisms absorb solar energy and transform it into chemical energy contained in the molecules of carbohydrates by using carbon dioxide and water. Thus, option B is correct.
What are the process involving in photosynthesis?The three episodes that occur during the photosynthesis cycle are: Light energy is absorbed by chlorophyll, which breaks down water molecules into oxygen and hydrogen. Light energy is converted into chemical energy. The reduction of carbon dioxide leads to the formation of carbohydrates.
The photosynthetic cycle contains three stages, which are as follows: Light energy is absorbed by chlorophyll, which then divides water molecules into oxygen and hydrogen. Light energy is converted into chemical energy. Carbon dioxide is reduced, which results in the creation of carbohydrates.

N = Number of atoms that remain after time t
No = Number of atoms originally present

0.125No/No = (1/2)^t/704 * 10^6
0.125 = (1/2)^t/704 * 10^6
(0.5)^3 = (0.5)^t/704 * 10^6
