The air then rises descends again, cools down, and the pressure increases. Air continues to circulate horizontally creating wind.
What is Wind?This is referred to as the moving form of air which is present and it is commonly as a result of the uneven heating of the Earth by the sun and the rotation of the earth.
The air which continues to circulate horizontally creates wind and the ones with a high pressure move to the areas with a low pressure. In the atmosphere, wind is responsible for certain activities such as in the reduction of the risk of suffocation as a result f the presence of many gases.

7.Type the correct part of the virus, indicated by the number 7,________9. Type the correct part of the virus, indicated by the number 9____________
The viruses have 3 main parts, the genetic material, the capsid, and some proteins.
in the image, we can see that inside we have the genetic material, and it is protected by the capsid. So the number 7 would be the genetic material.
and the number 9 would be glycoproteins that help the virus to recognize the target cell and allow the viruses to get in the cell, besides keeping the integrity of the genetic material.

sex determination explain x chromosome and y chromosome
Okay bro, i can explain you :)
Sex determination.
Separate sex determining i.e. male and female.
In sex determination, male and female differs only through sex chromosomes i.e. x and y chromosome. x chromosome for male and y chromosome for female. Autosomes(non - reproductive cells) does not involve in sex determination. Only the sex chromosomes involve in sex determination. Overall, only this chromosomes ( x and y) decides whether the resultant baby is male or female. If it is x chromosome, then it is a female and if y chromosome, then it is a male.
Which color of eyes is dominant? How do you know this?What does this mean in terms of inheritance?
The exercise tells us that 20 babies have been born in a maternity ward, and 10 of them have brown eyes, while the other 10, have blue eyes. The questions below are related to the dominant eye color, how we know it, and what it means in terms of inheritance. To this, we can answer that the dominant eye color is the brown one and that we know this due to the dominant alleles are represented with a capital letter, in this case, B, being b (for blue color) the recessive allele. In terms of inheritance, this means that if a parent with brown eyes (being BB, or Bb their genotype, but if we have that they have babies being they blue-eyed, then the genotype would be Bb), has babies with a parent that have blue eyes (being bb their genotype), the babies would have both phenotypes, as we can see in the following Punnet Square.

(C) 30%
(D) 70%
If 30% of the nucleotides in a single-stranded RNA molecule are adenine, then what percent are expected to be thymine (C) 30%
Why is adenine present in RNA?Adenine is a basic nucleotide that combines with uracil in RNA and thymine in DNA to produce nucleotides. Adenine; Adenine has a number of roles in biochemistry, including supporting cellular respiration through the production of ATP, NAD, and FAD. Additionally, DNA and RNA's chemical components are used in the creation of proteins.
One of the two purine nucleobases—the other being guanine—used to create the nucleotides of the nucleic acids is adenine. Adenine and thymine form two hydrogen bonds in DNA to help stabilise the nucleic acid structures. Adenine interacts to uracil in the RNA that is needed to create proteins.
Carbon, hydrogen, and nitrogen are the elements that make up the nitrogenous base adenine.

The nerve cells in the human nervous system seldom undergo mitosis. Based on this information,explain why complete recovery from injuries to the nervous system may not occur.
Nerve cells are referred to as amitotic because they lack centriole, which prevents them from undergoing mitosis and dividing to create new cells. Due to the incapacity of nerve cells to repair or regenerate, injuries to the nervous system can permanently harm or cripple a person.
What is a Nervous system?The brain, spinal cord, and a sophisticated nerve network are all parts of the nervous system. The brain and the body are communicated with via this system. All bodily functions are managed by the brain. From the brain, the spinal cord descends via the back.

The processes of the alterations in chromosomal organisation that take place as a cell enters mitosis.
The correct order is:
1. Chromatin is created by the regular wrapping of DNA around histones.
2. The DNA is compacted by interactions between histone component components.
3. The DNA becomes supercoiled as the chromosome coils ever-tighter.
4. Chromosomes that have been duplicated and compressed attach at a point known as the centromere.
What transpires to DNA throughout mitosis?
Therefore, during mitosis, cells don't simply randomly split their DNA into two heaps for the two daughter cells. Instead, they divided up their duplicate chromosomes in a methodical order. Prophase, Metaphase, Anaphase, and Telophase are the four basic phases of mitosis.
In what way do chromosomes separate during mitosis?
A mitotic spindle, a specialised structure made of microtubules, is responsible for separating the chromosomes. The cell's cytoplasm divides during this phase. It starts as soon as mitosis is complete.

The digestive system takes nutrients from food and absorbs them. The circulatory system drives those nutrients to the rest of the body's cells. From the left to the right: blood vessels, heart, villi, digestive tract.
How do the digestive and circulatory systems work together?1. The digestive system is composed of different organs. Some of them mechanically break down ingested food, while others, through enzymatic action, take nutrients and let them available to be absorbed by the intestine. Villi increase the absorption area, enhancing the number of nutrients and water absorption. These are then driven to the rest of the body's cells
2. The circulatory system (composed of vessels, capillaries, veins, arteries, and the heart) takes those nutrients from the intestine walls and transports them together with the oxygen to different cells in the organisms where they are needed.

To improve the quality of life for those who have had amputations, medical and bioengineering studies have dug into various elements of the body.
Circulatory system: Veins oxygenate all tissues and organs. To prevent a painful death after an amputation, the veins must be clipped and changed. To avoid dying portions, blood must flow properly.
Bones: without them, the body would be shapeless. Amputations require cutting and adapting bones to support a prosthesis.
Nervous system: All human nerves have stimuli receptors. After an amputation, nerves must be adjusted to prevent pain and discomfort from prostheses.
Muscular system: Muscles and bones allow movement. After an amputation, muscles must be changed to maximize movement and morphology for prosthetics.
