Answer:
translation; mRNA --> protein.
It includes three steps: initiation, elongation, and termination.
Explanation:
After the mRNA is processed, it carries the instructions to a ribosome in the cytoplasm. Translation occurs at the ribosome, which consists of rRNA and proteins
How do the respiratory and circulatory systems work together to maintain homeostasis, particularly during strenuous/intense exercise?
Mr. Shepherd is at a football game on a cold day. How does his body maintain a relatively constant body temperature? What is this process called?
Answer:
1. Mr. Shepherd maintain a relative constant body temperature by preventing loss of heat.
2 This process is called HOMEOSTASIS
Explanation:
Homeostasis is the process whereby living organisms maintain a stable internal environment despite changes in conditions to the external environment. It is necessary that the body undergoes this process in order to guarantee survival.
According to this question, Mr. Shepherd is at a football game on a cold day. This means that in order to maintain a stable internal temperature, the body must preserve heat in the body and prevent its loss via sweating.
The regulation of body temperature is maintain fundamentally by the thermoregulatory center located in the preoptic region of the hypothalamus, this process is called homeostasis, which is the balance that occurs in the internal environment.
The main thermoregulatory mechanism is the increase or decrease in blood flow to the skin, through vasodilation and vasoconstriction.
Thermal sensing cells or thermal sensors for heat and cold are located on the skin surface (peripheral receptors), in the pre-optic region of the anterior hypothalamus (central receptors) and in other parts of the body.When it is hot, blood circulation to the skin increases (it becomes red) and when it is cold it decreases (the skin becomes paler).In addition to blood flow, the body also uses sweat to regulate temperature, sweating evaporates water on the surface of the skin and heat is lost, thereby lowering body temperature.Therefore, we can conclude that the maintenance of body temperature is closely related to another important indicator, the internal environment (homeostasis).

the anthers in this flower located above or below the stigma
Answer:
The anther produces pollen (male reproductive cells). The filament holds the anther up. During the process of fertilization, pollen lands on the stigma, a tube grows down the style and enters the ovary. Male reproductive cells travel down the tube and join with the ovule, fertilizing it.

How are carbon dioxide and oxygen exchanged in the lungs?
A. Large blood vessels constrict and enlarge near the the lung tissue so gases can be exchanged.
B. Carbon dioxide and oxygen are exchanged in the aorta.
C. Small blood vessels pass next to the air sacs of the lung, gases are exchanged across a thin membrane.
D. The walls of the arteries thicken, harden, and lose their elasticity so that oxygen can pass through them.
Lung air sacs are surrounded by small blood veins, and a thin membrane allows for the exchange of gases (option C).
What is the purpose of oxygen?The chemical process that generates energy and powers the metabolisms of most living things, respiration, depends heavily on oxygen. The oxygen in the air that we breathe is essential for the survival of humans and many other animals.
O2 gas is it just O2?The sole sort of atom in oxygen makes it a chemical element, which is a substance. An oxidizing agent has eight atoms in its nucleus, as indicated by its atomic number of 8, which is represented by the letter O in its official chemical formula. At room temperature, oxygen is a gas that lacks all other flavors, smells, and colors. Molecular oxygen can be found in nature.

What is an antigen?
Answer:
In immunology, an antigen is a molecule or molecular structure, such as may be present on the outside of a pathogen, that can be bound by an antigen-specific antibody or B-cell antigen receptor. The presence of antigens in the body normally triggers an immune response.
The nucleus of a cell is most responsible for what function?
Answer:
The main function of the cell nucleus is to control gene expression and to mediate DNA replication during the cell cycle. The nucleus provides a site for transcription in the cytoplasm, allowing levels of regulation that are not available in prokaryotes.

Francis grew some plants for a science experiment. The sketch of his experiment after several days is shown. Which tropism is Francis most likely investigating?
The correct answer to this open question is the following.
Unfortunately, you did not provide the sketch or the photo that shows what Francis is doing. So we do not know what you are talking about.
However, trying to help you, we did some deep research and can comment on the following.
If the photo shows a plan under the light of a lamp, moving towards the lamp direction, then tropism is Francis most likely investigating is phototropism.
To better understand the concept, Tropism is the movement of a plant towards the direction of an influence exerted on it. This means that an external factor is introduced in order to make the plant grow through an external influence.
So when we use the term phototropism, this means that the plant responds to the direction of the source of light and grows in that direction. That is what Francis is using in his science experiment.
Answer:
phototropism

In order to create a big storm, the HIGH LEVEL TEMPERATURE had to be... A.Very Cold B.Cold C.Cool
Answer:
A, because in order to create a big storm, the temperature has to be at least 40-20 degrees Fahrenheit (below 30 is freezing point, aka snow), and that would be weather where you would need to wear a thick jacket and warm pants.

A. Describe the role of the promoter in eukaryotic gene expression. Explain how a negative regulatory molecule could inhibit transcription at the promoter.
B. Identify TWO events that occur during RNA processing. Explain how RNA splicing increases the variation of mRNA molecules.
C. Describe the role of miRNA in gene expression.
Answer:
Explanation:
A. The role of promoter in eukariotic gene expression is It is to bind transcription factors that regulate transcription initiation. This molecule is so important because control the binding of RNA polymerase to DNA. The promoter region may be short or very long; the longer the promoter is, the more protein binding space is available. A negative regulatory molecule has the possibilty to inhibit transcription at the promoter because these molecules block the binding of RNA polymerase to the promoter region, thus not allowing the initiation of transcription, in some particular cases, the negative regulator binds to the lac repressor and will bind to the promoter in the same site where RNA polymerase would bind to.
B. Two process that occur during RNA processing are RNA splicing and 5′ capping, 3′. RNA splicing is a procces known for removing the introns from the pre-RNA and stuck back together the restant parts, exons. This process has as a goal form a mature mRNA that does not contain the intron sequences. RNA splicing has effect on variation of mRNA molecules because through a process called alternative splicing more than one mRNA can be made from the same gene.
C. Even though they are not quite the same thing miRNA and negative regulatory molecules have the same role, which is inhibit the translation and silence genes. They regulate gene expression by binding to the 3'-UTR of their target mRNAs and destabilizing the mRNA and translational silencing, repressing protein production. Even so, under specific circumstances, miRNA can activate translation or regulate transcription.
