C) warm and moist
D) cold and dry
I need this today please help

Answers

Answer:

I'm pretty sure its c

Explanation:

Warm and moist kind of air mass forms over tropical waters that have been heated by the sun. Hence option C is correct.

What are topical waters?

Topical waters are defined as water between the Tropic of Cancer (23.5° North latitude) and the Tropic of Capricorn (23.5° South latitude). In the Köppen climatic classification, a tropical climate is one in which the average monthly temperature is over 18°C. There is no winter season and there is more annual rainfall than annual evaporation.

A good illustration of this kind of fish is the goldfish. On the other hand, "tropical" or "warm water" fish require a water temperature that is optimal for their comfort and health. Although different species of fish have varying needs, tropical fish generally demand water that is between 76 and 80 degrees Fahrenheit (25 and 27 degrees Celsius).


Thus, warm and moist kind of air mass forms over tropical waters that have been heated by the sun. Hence option C 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.

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.

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.

I is not related to the function of the digestive system. It only describes the "esophagus."

II is called the "Peristalsis." This is one of the functions of the digestive system. This allows the food to move down the GI tract.

III is part of the process called "Segmentation." This is one of the functions of the digestive system. The increase surface area of the microvilli expands 25 times and this allows greater absorption of food.
