A virus mutates and evolves,which is the trait of a living being
What is a virus?
A host is required for the growth of viruses, which are microscopic infectious organisms that contain genetic material, either DNA or RNA.
Viruses are living organisms that can only survive and grow in a host, which is a living thing like a person, an animal, or a plant. Like cell-based life, viruses are subject to evolution and natural selection, and the majority of them change quickly mimicking living cells have led to numerous outbreaks of illness and fatalities throughout human history.
Therefore the virus evolves like a living being

q4.1. without mutations, and with no crabs present, snails produce offspring that have the same shell thickness as themselves (they clone themselves). will this change when you add crabs? why or why not?
No, because there is no mechanism for a snail to produce offspring with a different shell thickness from itself, thus the answer option (D).
The population does not experience changes in shell thickness. Some snails in the population experience changes in shell thickness.
Predators are creatures that go on the search for prey to eat. There are various creatures that prey on crabs, including otters, alligators, fish, and even shrimp (they eat the larvae). Predators are animals that hunt other animals or living things for food, whereas prey is little animals or organisms that eat the food that the predator leaves behind after it has eaten it.

_______ also known as thyromegaly, is an abnormal enlargement of the thyroid gland that produces a swelling in the front of the neck.
Thyromegaly is a disorder in which the thyroid gland — the butterfly-shaped gland in the neck — becomes abnormally enlarged.
What causes the thyroid gland to enlarge?Iodine deficiency is the most common cause of goiter. The body needs iodine to produce thyroid hormone. If you do not have enough iodine in your diet, the thyroid gets larger to try and capture all the iodine it can, so it can make the right amount of thyroid hormone.The neck is examined for scars, masses, glandular or nodal enlargement, and so on. Examine the trachea for any deviations. Next, as the patient swallows, examine the thyroid gland for any enlargement. The trachea should be midline, and there should be no visible swelling of the lymph nodes or thyroid gland. Take note of the patient's speech. They should be able to speak clearly and without slurring or garbling.Examine the skull and face. Examine the skin and scalp. Skull palpate (especially if patient complains of tenderness or recent trauma). Examine your facial sensation and motor function. Neck abnormalities can have a local etiology (e.g., infection, neoplasm, trauma) or be a symptom of a more general disorder (eg, curvature, spondylosis, leukemia, systemic).The correct order is:

Gel electrophoresis is a laboratory method used to separate mixtures of DNA, RNA, or proteins according to molecular size.
In gel electrophoresis, the molecules to be separated are pushed by an electrical field through a gel that contains small pores. The speed at which the molecules move through the pores in the gel is inversely proportional to their lengths. This indicates that a smaller DNA molecule will move through the gel further than a larger DNA molecule.
In polyacrylamide gel electrophoresis, proteins move through pores in a polyacrylamide gel matrix in response to an electrical field; pore size shrinks with increasing acrylamide concentration. The protein migrates at a rate that depends on the pore size, protein charge, size, and shape.

Investigators examined the expression of transporter mRNA and protein produced in zebrafish homozygous for each of the alleles and found the results summarized below Does the allele associated with light color appear to be altering transcription or translation? Why?
The light colored allele appears to alter transcription and therefore the corresponding mRNA is absent in the homozygous zebrafish.
The protein we can tell was absent because the mRNA required for protein synthesis was not present. If the allele had altered translation, the mRNA that is functional would be present but in the same case, the protein would still be absent. Amino acid/carnitine transporters B(0,+) (ATB(0,+)) and broad neutral (0) amino acid transporter 1(B(0)AT1) The mRNA levels measured in our study suggest that the protein may be used by the duration of 24 -96 hours of fasting in zebrafish.

What is Tubular reabsorption ?
Drugs are passively reabsorbed into the systemic circulation through the lumen of the distal tubules in a process known as tubular reabsorption. Only non-ionized molecules are available for reabsorption, much like with enteral absorption. As a result, medications that change the pH of the urine may result in enhanced tubular reabsorption of other medications. A typical example is the mildly acidic medication phenobarbital. In cases of overdose, sodium bicarbonate is used to alkalinize the urine in the hopes that phenobarbital will become more ionised there, reducing tubular reabsorption and promoting faster excretion. The efficacy of this therapy is unclear, though.
The second crucial step in the production of urine is tubular reabsorption. Reabsorption may be passive for other ions, such as water, or it may be active, as in the cases of glucose, amino acids, and peptides. In the distal tubule and the collecting duct, water and ions are also reabsorbed.

The connection between a motor neuron and a muscle cell is called the neuromuscular junction. Here, impulses are transmitted between the nervous system and the muscles, propagating the action potential that will lead to muscle contraction.
The mechanism by which an electrical signal in a muscle cell leads that muscle cell to mechanically shorten is known as excitation-contraction coupling or ECC. The excitation phase and contraction phase are two interconnected phases that makeup ECC, as the name would imply.
An action potential is produced within the muscle cell during excitation. An electrical event, such as an action potential, involves a change in charge. Motor neurons transmit the electrical signal from the nerve that causes muscle cell contraction to the muscles. The neuromuscular junction is the point where a motor neuron meets a muscle cell. Here, the action potential that will cause a muscular contraction is propagated by impulses between the nervous system and the muscles.
A physical alteration to the form of the muscle cell is referred to as contraction (also called muscle fiber). A muscle fiber shortens when it contracts.

The enzyme lactase helps the digestive system break down lactose, a disaccharide found in milk, into the monosaccharides glucose and galactose. Lactose-intolerant individuals have low levels of lactase production and therefore have difficulty digesting dairy products. A common test for lactose intolerance is to measure blood sugar (glucose) levels after consuming a drink containing lactose. Which of the following test results would you expect to see for a lactose-intolerant person? Multiple Choice Blood sugar levels are unaffected by drinking a lactose solution Blood sugar levels is rapidly immediately after anning actose solution Blood or even roetely one in conto
The expected test result for a lactose-intolerant person is Blood sugar levels are unaffected by drinking a lactose solution.
Lactose is divided into glucose and galactose during digestion by the enzyme lactase, which is produced by the cells of the small intestine. Lactase enzyme is not formed in lactose intolerant people. As a result, when a lactose-intolerant person consumes lactose solution, lactose is not completely digested and is not broken down into the two monosaccharides glucose and galactose. The villi of the small intestine do not absorb glucose, so drinking a lactose solution by a lactose-intolerant person has no effect on blood sugar levels.
Because lactose is not entirely digested in lactose-intolerant people, blood sugar levels do not rise rapidly after drinking lactose solution. Lactose consumption by lactose-intolerant people has no effect on blood sugar levels because there is no complete digestion. As a result, drinking a lactose solution does not cause a rapid drop in blood sugar levels.
As a result, the correct answer is that drinking lactose solution has no effect on blood sugar levels.
