After a police car with flashing lights and blaring siren passes Tom and pulls over another driver for speeding, Tom's heartbeat soon slows down, his blood pressure decreases, and he stops sweating. These calming physical reactions are MOST directly regulated by his _____ nervous system.
Answer:
Parasympathetic
Explanation:
The parasympathetic nervous system predominates in quiet “rest and digest” conditions while the sympathetic nervous system drives the “fight or flight” response in stressful situations. The main purpose of the PNS is to conserve energy to be used later and to regulate bodily functions like digestion and urination. That is why the Parasympathetic Nervous System is being used in this scenario. Hope this helped :)

The amino acid chain which will be formed by the codons "ACU CCA UCG" will be Threonine-Proline-Serine. Thus, the correct option will be B.
What is amino acid chain?An amino acid can be defined as the fundamental molecule which serves as the building block for protein molecules in the body. There are about twenty different amino acid molecules present inside the body of an organism. A protein molecule consists of one or more chains of amino acid molecules called as polypeptides whose sequence is encoded in a gene.
Different codons are present in the cell which encodes for different amino acids. A codon is a set of three nucleotides which encode amino acid molecules. ACU codon encode for threonine amino acid, CCA encode for Proline amino acid, and UCG encode for Serine amino acid.
Therefore, the correct option will be B.

Cereals and legumes are complementary in the diet because Group of answer choices Cereals counteract the antinutritional factors in legumes A diet combining legumes and cereals will have a good balance of essential amino acids Cereals are high in lysine Legumes are high in cysteine and methionine
Answer:
A diet combining legumes and cereals will have a good balance of essential amino acids
Explanation:
Cereals are grains that are rich in vitamins, carbohydrates, protein and other essential nutrients, they include wheat, rice, sorghum etc. Legumes include a wide range of seeds, fruits, nuts, vegetables that are rich in proteins, carbohydrates and other nutrients, examples include peas, beans, lentils etc.
Cereals and legumes are referred to as staple foods, they are usually used to complement each other because combining them will result in a good balance of essential amino acids. In cereals, lysine is a limiting amino acid but is usually in high amounts in legumes. However, in legumes cysteine, trypthophan and methionine are the limiting amino acids but are found in cereals. Therefore, this makes legumes and cereals complementary in the diet as it significantly increases the protein quality of the diet.

Explain why eating a meal with too much salt leads to production of small volume of concentrated urine.
Answer:
the urine is burned up by salt which will evaporate
Answer:
Eating a meal with too much salt leads to a decrease in the water potential of blood. This fall in water potential is detected by the osmoreceptors in the hypothalamus (in brain). The hypothalamus stimulates the pituitary gland to release antidiuretic hormone (ADH). The walls of the collecting duct in the kidney become more permeable to water, hence, a greater proportion of water is reabsorbed from the urine back into the blood by osmosis.
As a result, a small volume of concentrated urine is formed.
Which best contrasts self-renewal and differentiation?
Answer:
Self-renewal is a kind of cell division specific to stem cells, so cell division is a general term. When self-renewal occurs, a stem cell divides into two cells, one of which is still a stem cell (which can display differentiation potential into one or more types of differentiated cells (stemness/potency) and divides almost indefinitely = self-renewal), and another is a differentiated cell, which may or may not divide, but its divisions (if any) are not self-renewal because (1) no stem cell (i.e. a cell with developmental potential) is produced, and (2) these divisions are finite (so they are not self-renewal, because self-renewal is indefinite yet controlled proliferation). In sum, self-renewal is a stem cell's 'unlimited' division while retaining its developmental potential.
Of note, stem cell immortality is thanks to the expression of the enzyme telomerase.

You are working on a legal case for the Environmental Protection Agency that is
suing a logging company for using unsustainable logging practices and
endangering the environment. In order to avoid paying heavy fines to the
government, the logging company can institute safer practices but they do not
know any. What can you suggest to them?
Answer:
Explanation:
The logging company should go by the rule governing the forest and seek for government permission before cutting down any tree. There are due processes that allows you cut some forest timbers after establishing a new one but this is done with the consent of the government and the agreement that is made between the company and the government. An agreement will be reached on how the cutting can be done to avoid total loss of our forest and areas that can be used.
Going through the right channel before cutting forest trees will help reduce the amount of fines they pay almost all the time they are caught from illegal cutting.
A forensic scientist is trying to find out the number of adenine bases in the DNA sample that he obtained from a crime scene. What can he assume about the number of adenine? The number of adenine bases will be equal to the number of guanine bases. The number of adenine bases will be equal to the total of all the other bases. The number of adenine bases will be equal to the number of thymine bases. The number of adenine bases will be half of the number of cytosine bases.
Answer:
The correct option is;
The number of adenine bases will be equal to the number of thymine bases
Explanation:
The four chemical bases that make up the DNA code are adenine (A), guanine (G), thymine (T), and cytosine (C) which are arranged based on a specif organism such that they represent the information regarding the building of the organism
The chemical bases of the DNA are found in pairs consisting of two chemical bases which are then known as base pairs. The possible base pairs are;
Adenine (A) pairing with thymine (T)
Cytosine (C) pairing with Guanine (G)
Therefore, the forensic scientist should expect to find that the number of adenine bases will be equal to the number of thymine bases.
Since the scientist was trying to find out the number of adenine bases in the DNA sample, assumption that the number of adenine would be equal to the number thymine would help.
According to the base-pairing rule of Chargaff, adenine always pairs with thymine while guanine always pairs with cytosine.
Going by this rule, we can say that the number of adenine must be equal to the number of thymine while the number of guanine must be equal to the number of cytosine in any DNA.

A blood lactic acid sample was collected in a gray-top tube that was drawn after sequentially filling red-top, green-top, and purple-top tubes. The lactate level was 30 mg/dL. A second lactic acid sample was ordered 1 hour later and drawn in a gray-top tube without filling any other tubes. The result was 20 mg/dL. What is the most likely explanation of this result
Answer:
Homeostasis has been established for a very long time. This must have affected the result of the first reading, which has become high.
Explanation:
Homeostasis refers to the state of equilibrium in the chemical and physical conditions of a system. The time it takes to establish, as well as the time it remains active within a system, provides different results, which are totally related to the homostatic forms presented.
The time between homeostasis in the blood lactic acid samples shown in the question above was what allowed the difference between the two reading results. The first result was high, because it was the result of an extended period of homeostasis.

Explanation:
Life on Earth, emerged in the hydrosphere, at least from the findings and data so far. The reason for that was that the atmosphere and the lithosphere were still in a faze were they were not very hospitable for any living organisms to develop. The hydrosphere, or the water bodies, on the other side, were enabling conditions for life, not perfect or as we have today, but still reasonably good, so the life started developing into the water environment, and after the atmosphere and lithosphere changed over time, it spread on them as well.

Is the escape of a rattlesnake from a zoo exhibit an example of an invasive species?
Answer:
No, it isn't
Explanation:
An invasive species is characterized by an organism's appearance in an area it is not a native of, with a high capacity of reproduction that will cause it to be a threat to native species in that area. A species of organism is tagged "invasive" if it is foreign to a region/location and possess a high reproductive rate that spreads fast and causes harm to other species.
Based on the analogy given in this question about the escape of a rattlesnake from a zoo, it cannot be ascertained that it is an example of invasive species. This is because rattlesnakes may be native to that area and possess a zero threat level to the environment in terms of high spreading rate.
