High and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.

If a cell has a diploid number of 8 (2n = 8) before meiosis, how many chromosomes will be in each of the four daughter cells after meiosis II if one pair of homologous chromosomes experiences nondisjunction in meiosis I? Show how you got the answer by drawing out the process, starting with the diploid cell undergoing meiosis I (where nondisjunction occurs) and then meiosis II to get the four daughter cells.
Answers
Answer:
The final product is four gametes, two of them with 5 chromosomes, and the other two with 3 chromosomes each.
Explanation:
If nondisjunction occurs during meiosis 1, a pair of homologous chromosomes fail to separate, and one of the daughter cells will have the two chromosomes while the other cell will not get any chromosome from the pair.
If meiosis 1 occurs normally, but nondisjunction occurs in meiosis 2, sister chromatids fail to separate.
The usual process of meiosis produces four daughter haploid cells (n) from a diploid germ cell (2n). Each daughter cell is haploid because they have half the number of chromosomes of the original one.
If the diploid number of the original cell is 8 (2n=8), then under normal conditions, each haploid daughter cell should have 4 chromosomes (n = 4).
But in the exposed example, one pair of homologous chromosomes experiences nondisjunction during meiosis I (in the attached file, you will recognize this pair as the red one). The other chromosomes separate as usual. So one of the daughter cells will have one extra chromosome than expected (five instead of four), and the other daughter cell will lack one chromosome (three instead of four). Meiosis II occurs normally. The final result is the formation of four gametes, two of them with 5 chromosomes, and the other two with 3 chromosomes each.

Answer:
b
Explanation:
edg 2021
The role of scientific knowledge in society is that the advances in scientific knowledge can be beneficial to society if applied responsibly. Thus, the correct option will be B.
What is the role of Scientific knowledge?Scientific knowledge is referred to as a generalized body of laws and theories which are used to explain a phenomenon or a behavior of interest that are acquired by people using the scientific method and knowledge.
Laws are observed patterns of phenomenon or behaviors, while the scientific theories are systematic explanations of the underlying phenomenon or the behavior observed.
The role of scientific knowledge in society is that the advances in the scientific knowledge can be beneficial to the society as a whole if applied responsibly.
Therefore, the correct option will be B.

Scientists found members of a plant species they did not recognize. They wanted to determine if the unknown species was related to one or more of four known species, A, B, C, and D. The relationship between species can be determined most accurately by comparing the results of gel electrophoresis of the DNA from different species. The chart below represents the results of gel electrophoresis of the DNA from the unknown plant species and the four known species.

Complete question:
Scientists found members of a plant species they did not recognize. They wanted to determine if the unknown species was related to one or more of four known species – A, B, C, D. The relationship between species can be determined by comparing the results of gel electrophoresis of the DNA from different species. The chart below represents the results of gel electrophoresis of the DNA from the unknown plant species and the four known species.
Which two known plant species is the unknown plant species most closely related to?
Answer:
Species C is the most closely related, followed by species D.
Explanation:
Gel electrophoresis technique is used to separate different fragments of DNI, RNA, and other macromolecules or proteins, concerning their size/weight and charge.
Gel electrophoresis of DNI lets us visualize how many different fragments of the molecule are present in a sample and how they differ from each other. The presence of fragments of the same size will be distinguished as a line named band. Each band represents many DNI fragments of similar size placed in the same position. The result of the gel electrophoresis will be different bands in different positions according to their sizes. The biggest ones will not migrate in the gel as much as the smallest ones.
In the exposed example we can assume that the most closely related species is C. The second most similar is species D.
The gel electrophoresis of the DNA from the unknown plant species resulted in five different bands, which means five types of fragments of different sizes.
Four of the five bands expressed by the unknown species coincide with the bands of species C. Species C only lack one band to be exactly the same.Species D coincides in three bands and lack two bands to be exactly the same as the unknown species. Species A only coincides in one band. Species B does not coincide in any band, meaning that this is the most different oneFor a better understanding, look at the attached files, where you will find the chart.

insulin and glucagon are produced in the;
Answers
Glucagon is a peptide hormone, PRODUCED by alpha cells of the pancreas.
Insulin is a hormone made by an organ located behind the stomach called the pancreas. There are specialised areas within the pancreas called islets of Langerhans (the term insulin comes from the Latin insula that means island).
And Islet cells in the pancreas are responsible for releasing both insulin and glucagon.
Glucagon raises concentration of glucose and fatty acids in the bloodstream, and is considered to be the main catabolic hormone of the body.[3] It is also used as a medication to treat a number of health conditions. Its effect is opposite to that of insulin, which lowers extracellular glucose.[4] It is produced from proglucagon, encoded by the GCG gene.

In humans, brown eyes are dominant to
blue eyes. What is the probability
that two heterozygous brown-eyed
parents will have a child with blue
eyes?
J. 25%
K. 50%
L. 75%
M. 100%
Answers
Answer:
j
Explanation:
since brown eyes are more dominant than blue eyes chances of it is 3/4
Answer:
The answer is J. 25%.
Explanation:
In this problem, we know brown eyes are dominant to blue eyes. We can let the dominant allele for brown eyes be represented by "B" and the recessive allele for blue eyes be represented by "b". Since it is given that both parents are heterozygous, we know that they must have the genotype Bb.
When two Bb individuals are crossed, the offspring will be 1 BB : 2 Bb : 1 bb, or 3 brown : 1 blue ratio. Therefore, 1/4 of the offspring will have blue eyes, which represents 25%. Thus, the correct answer is choice J, 25%.

First measure the swings of the pendulum at its original weight. After that some weight is removed from the pendulum and again measure the number of swing of pendulum at specific time period. We have to reduce mass of pendulum and then measure the number of swings. In this way, this experiment moves forward and we can find out the impact of mass on the speed of pendulum.
