In interstitial growth of cartilage ______. Multiple choice question. only new cells are produced only new matrix is produced news cells and new matrix are produced

Answers

Answer:

The correct answer is ''news cells and new matrix are produced''

Explanation:

Interstitial growth consists of the production of new layers of cartilage in the inner layer of the perichondrium. This process occurs because chondrocytes meet in the form of small groups, called isogens or cell nests, they are capable of dividing and the cartilaginous matrix is distensible. Daughter cells initially occupy the same gap but as they secrete new intercellular matrix they separate. These daughter cells can divide again, forming so-called isogenic groups, which are frequently found in growing cartilage.

Large biomolecules and macromolecules known as proteins are made up of one or more extended chains of amino acid residues. Proteins are responsible for the structures and functions of organisms.

What is Protein?

Large, intricate molecules classified as proteins perform an array of essential roles in the human body. They are fundamental for the structure, operation, and control of the body's tissues and organs and perform out the majority of their work inside cells.

Many thousands of amino acids, which seem to be smaller components that make up proteins, are linked together in lengthy chains to form proteins. To form a protein, 20 different kinds of amino acids can be mixed. Each protein's precise function and characteristic 3-dimensional structure are established by its amino acid sequence.

Thus, Proteins are responsible for the structures and functions of organisms.

When a muscle relaxes: Question 10 options: crossbridges form and muscle extensibility returns the muscle to rest length. crossbridges form and muscle elasticity returns the muscle to rest length. crossbridges stop forming and muscle elasticity returns the muscle to rest length. crossbridges stop forming and muscle extensibility returns the muscle to rest length

Answers

Answer:

When a muscle relaxes,

crossbridges stop forming and muscle elasticity returns the muscle to rest length.

Explanation:

Relaxation occurs when stimulation of the nerve stops. Calcium is then pumped back into the sarcoplasmic reticulum breaking the link between actin and myosin. Actin and myosin return to their unbound state causing the muscle to relax. Alternatively relaxation will also occur when ATP is no longer available.

Answer:

B. Bald eagles are hunted until near extinction, population recovers

Explanation:

A bottleneck effect can arise when the population of a species is drastically reduced by an occurrence. Human activities plays a major role in regard to creating a bottleneck effect in our present day. Human activities such as overhunting result into bottleneck effect. When overhunting reduces the population of a particular species, the few individuals left would have a reduced genetic variation which is not representative of the original population. The few individuals left further reproduces individuals of their kind carrying a genetic composition that is different from the original gene composition of the old population.

The case of the hunting of bald eagles until near extinction before they begin to recover is a perfect case of the bottleneck effect. Only a small proportion of the eagles original population survives. Generic variation reduces. The genetic variation in the new population of the bald eagles will be different from that of the original population.

A student combined equal amounts of two solutions. One solution had a pH of 2 and the other had a pH of 12. Which would most likely be the resulting pH?

Answers

Answer:

This question lacks options, the options are:

A. 1

B. 3

C. 6

D. 11

The answer is C. 6

Explanation:

pH of a solution refers to the concentration of hydrogen ions in that solution. A scale is used to measure pH of a solution.

* A pH value less than (<) 7 is said to be ACIDIC. The lesser the number, the more acidic

* A pH value of exactly 7 is said to be NEUTRAL

* A pH value above (>) 7 is said to be BASIC OR ALKALINE. The higher the number, the more alkaline.

According to this question, two solutions of equal volume with pH values of 2 and 12 respectively were combined. Based on the explanation of pH scale, the solution with pH 2 is said to be very ACIDIC while the solution with pH 12 is said to be very ALKALINE.

Hence, if this two solutions are combined, a neutralization will occur which will result to a solution with close to neutral pH (7). In the above options, 6 is the closest pH value to NEUTRAL and hence, the most likely pH of the resulting solution.

For young men of age 20, there have been 150 rounds of DNA replication during sperm production as compared to only 23 rounds for a woman of age 20. That is a 6.5-fold greater number of cell divisions and proportionately greater opportunity for new point mutations. Yet, on average, 20-year-old men contribute only about twice as many new point mutations to their offspring as do women. How can you explain this discrepancy

Answers

Answer:

A plausible hypothesis is that deleterious germline mutations in sperm cells are removed by natural selection since sperms have to compete to fertilize the egg

Explanation:

Sperm cells need to travel through the cervix in order to reach the uterus and fertilize the egg. During this process (which is called 'fertilization'), approximately 300 million sperm cells have to compete in a race to reach an egg. During fertilization, the majority of sperm cells die off quickly because male germinal cells carry mutations that lead to abnormalities (e.g., many sperms have double heads, others no tail, etc). The sperm cells are considered to be physiologically weak because their normal functions can be easily disrupted by mutations and, simultaneously, they are under strong selective pressure to be selected during the sperm race. In consequence, deleterious germline male mutations are expected to be eliminated by natural selection, thereby sperms are selected before fertilization so only the strongest ones can compete in the race to fuse with the egg cell and thus develop one zygote.

what are the limitations of using fossil in evolution theory. Please answer​

Answers

The limitations of using fossil in evolution theory are that fossils are rare and only show changes in bones of animals. In many environments the preservation of fossils is hard creating gaps in fossil records that can make identifying change very hard. And when changes present themselves they can be in many forms, such as changing in the soft tissue, coverage and thickness of hair, and changes in organs, all of which can not be preserved by fossilization.
