What are the different types of chromosomal abnormalities?

Chromosomal abnormalities are of different types; some are related to autosomes, and some are related to X and Y chromosomes. The down syndrome happens due to the trisomy in the 21st chromosome, which means instead of two chromosomes, there are three chromosomes.

In Patau syndrome, the trisomy is seen in the 13th pair of homologous chromosomes, and as a result, instead of two chromosomes, three are present. Klinefelter syndrome is associated with males who have an extra X chromosome. Infertility is observed as a result of this male display of female characteristics, such as behavioral changes. Turner syndrome is associated with females who have lost one X chromosome.

As a result, the correct answer is option D, which is Klinefelter syndrome, which is XXY.

Stand and let your hands hang next to your sides for a few minutes. Then, look at the backs of your hands. Do you see any bumps on the surface on top of your veins? What might those be, and what are their function?​

Answers

When you stand and let your hands hang next to your sides for a few minutes, the bumps you see on your veins are the valves that help move blood to the larger veins.

What we know about vein valves.

There are valves located throughout the veins in our bodies. Most of these are located in points where smaller venules fuse with the larger veins.

Their function is to prevent blood from flowing back into the smaller veins, thus helping with the normal blood flow of the body.

Given that the veins in our bodies are littered with small valves to help the blood return to the heart correctly, we can confirm that these are the small bumps that we can see when letting our hands down for a few mins, as they fill with the blood they try not to let flow back into the smaller veins.

1. Explain how forces of attraction and repulsion exist within an atom.

Answers

Answer:

Oppositely charged particles attract each other, while like particles repel one another. Electrons are kept in the orbit around the nucleus by the electromagnetic force, because the nucleus in the center of the atom is positively charged and attracts the negatively charged electrons.

Explanation:

Answer:

1. Electrons surrounding a nucleus are attracted to the protons within it because electrons and protons have opposite charges. Electrons closest to the nucleus are attracted with such a force that they can’t escape from the atom. These electrons tend to shield the protons from electrons that are farther away because electrons have the same charge and repel each other. Electrons that are farther away have less attraction to the protons within the nucleus and are more likely to be detached from the atom.

2. Electrons can be transferred from atoms of one body to atoms of another body through friction. This can occur when one body is rubbed against another or when a liquid flows across a solid. In either case, one body may be given a positive charge while the other body is given a negative charge of the same magnitude. Both charges are developed at the same time. Electrons can also be transferred from one body to another when a charged body comes into contact with an uncharged body. The electrons move in the direction that will equalize the charges; thus, the uncharged body will be given the same charge as the charged body.

3. Free electrons move from points of negative charge to points of positive charge. When these electrons move freely from one point to another with little resistance, the material they’re traveling through is said to be a conductor. Conductors have a large number of free electrons. Insulators, on the other hand, have very few free electrons and offer great resistance to the movement of these electrons. Electric charges produced on one end of a body composed of insulating materials will most likely not spread throughout the body. In a conductor, this charge would spread throughout the entire body. Metals are generally conductors; oils, rubber, air, porcelain, and plastics are good insulators.

4.

Lightning is produced by the rapid transfer of free electrons when one of the following conditions exist: One part of a cloud is positively charged and a neighboring part of the same cloud is negatively charged. A positively charged cloud comes near a negatively charged cloud. A cloud with either a positive charge or a negative charge comes near the earth.

B. It creates organisms with better adaptability to the environment.
C. It allows all types of cells to produce two sets of identical chromosomes.
D. It produces up to eight diploid cells, each with the same number of chromosomes.

Answers

D because the diploid cells

In meiosis sexual reproduction produce haploid cells to produce gametes and chromosome number is reduced, hence option a is correct.

What is meiosis in sexual reproduction?

Gametes or sex cells, which are needed for sexual reproduction are created during meiosis.

It deactivates the sporophytic information while activating the genetic information for the production of sex cells.

Meiosis is a kind of cell division that results in the production of four gamete cells and a 50% reduction in the number of chromosomes in the parent cell. To develop egg and sperm cells for sexual reproduction, this procedure is necessary.

Therefore in sexually reproducing organisms meiosis is important to produce gametes, hence option a is correct.

A. Suzie Q wants to know the effect of different colors of light on the growth of plants. She believes that plants can survive best in white light. She buys 5 ferns of the same species, which are all approximately the same age and height. She places one in white light, one in blue light, one in green light, one in red light and one in the closet. All of the ferns are planted in Miracle-Grow and given 20 mL of water once a day for 2 weeks. After the two weeks, Suzie observes the plants and makes measurements.

Answers

Answer:

This question is incomplete, the complete part is: What is the independent variable in this experiment? A) The plant species B) The amount of water that each plant gets C) The amount of time D) The different types of light the plants were put under.

The answer is D

Explanation:

In an experiment, the INDEPENDENT VARIABLE is the variable that is changed or manipulated by the experimenter in order to effect a measurable response.

In this case, Suzie Q wants to know the effect of different colors of light on the growth of plants. She conducts this experiment using different colors of light namely: white light, green light, blue light, red light etc. This shows that the variable being changed/manipulated is the different colors of light. Hence, the INDEPENDENT VARIABLE is the DIFFERENT TYPES OF LIGHT THE PLANT WERE PUT UNDER.
