On April 26, 1986, Reactor 4 at the Chernobyl Nuclear Power Station in Ukraine exploded, releasing radioactive isotopes into the air. The majority of the isotopes that were released and spreading thousands of miles were of the element iodine. As a class, discuss what endocrine glands would be most affected and how it would become apparent in the nearby population.

Answers

Answer 1
Answer:

The thyroid gland will be mostly affected in this case. The element Iodine is

the major precursor which is involved in the formation of two hormones.

Thyroid hormones

  • Triiodothyronine (T3)
  • Thyroxine (T4).

When an individual is exposed to radioactive iodine , it alters the production

of the hormones which leads to series of effects such as:

  • Decreased metabolism
  • Low body weight
  • Goitre etc.

Answer 2
Answer:

Answer:

In the given case, the thyroid gland will be affected the most due to the exposure of the element iodine. For the synthesis of thyroid gland hormone, T3 and T4 iodine is required. As the exposure of the radioactive iodine element is taking place, therefore, it will result in the deterioration of the thyroid gland. Radioactive iodine is generally used in the treatment of hyperthyroidism.  

However, in normal individuals, the exposure of the radioactive iodine element results in a decrease in the level of thyroid hormones below the normal level due to the destruction of the thyroid cells. The symptoms seen can be neck tenderness, swollen salivary gland, and loss in body weight.

Which of the following features is not universally accepted as a sign of physical attractiveness? A. facial symmetry B. a curvy figure C. average body type D. average features Please select the best answer from the choices provided A B C D

Answers

A curvy figure is not a universally accepted sign of physical attractiveness. Therefore option “B” is correct.

What is physical attractiveness?

It is the measure of the degree to which a person can look and aesthetic pleasing.  Facial symmetry and sociocultural and personal choices of a person are evaluating factors.

Facial symmetry is based on the symmetry of the face of a person and youthfulness. It helps in determining the beauty of a person.

Sociocultural depend on how a person combines both social and cultural factors. Factors affecting are such as personal beliefs,  and values. Personal choices vary from person to person as everyone has different choices.

Physical attractiveness is the evaluation of the physical appearance of a person.

Explanation:

Which statements compare meiosis I and meiosis II? Check all that apply.-The parent cell in meiosis I is diploid and has 2n chromosomes.
-Meiosis I produces two gametes that have exactly the same genetic make up.
-Meiosis II creates four daughter cells that are genetically different from one another.
-After meiosis I, two daughter cells with haploid number of sister chromatids are produced.
-Four gametes with haploid number of chromosomes and single chromatids result after meiosis II.

Answers

Answer:

after meiosis I two daughter cells with haploid number of sister chromatids are produced.

the parent cell in meiosis I is diploid and has 2n chromosomes.

four gametes with haploid number of chromosomes and single chromatids result after meiosis II.

Explanation:

Answer:

Meiosis II creates four daughter cells that are genetically different from one another.

After meiosis I, two daughter cells with haploid number of sister chromatids are produced.

Four gametes with haploid number of chromosomes and single chromatids result after meiosis II.

Explanation:

Medication that relieves pain but also slows respiration _____

Answers

Ans.

Opiates are medications that can be used as painkillers. These are derived from the opium. Opiates reduce pain as they act as CNS (central nervous system) depressants. The CNS is also associated with regulation of heart beat and respiration. Thus, the opiates also slow down the respiration by slow down the CNS.

Hence, the correct answer is 'opiates.'

Was the rate of increase of sucrase activity greater when sucrose concentration went from 2.5 to 7.5 g/l or when it went from 22.5 to 27.5 g/l?

Answers

Answer: It is greater when sucrose concentration went from 2.5 to 7.5g/l.

Explanation: The rate of reaction of an enzyme is known to be affected by the rate of concentration of its substrate, which in this case is the sucrose Solution.

If the rate of increase of concentration is high,the activities of the enzyme SUCRASE will increase accordingly, in order to breakdown the substrate.

The rate of increase of Sucrose from 2.5 to 7.5g/l is higher(300%) than the rate of Increase of Sucrose from 22.5 to 27.5g/l (1.22%). It is expected under circumstances that the action of SUCRASE will increase at a rate higher in the first Solution than in the second Solution.

Final answer:

The rate of increase in sucrase activity depends on the concentration of sucrose and whether or not the enzyme is saturated. The increase could be greater at lower concentrations (2.5 to 7.5 g/l) if sucrase is not yet saturated. The increase might be less at higher concentrations (22.5 to 27.5 g/l) if sucrase is near or at saturation point.

Explanation:

The increase in sucrase activity is generally considered to be a response to the concentration of substrate present, in this case, sucrose. The increase in activity happens because more substrate (sucrose) is available for the enzyme (sucrase) to act upon. However, there is a limit to this increase. Once the enzyme is saturated with substrate, further increases in substrate concentration do not increase the enzyme's activity. This is known as the saturation point.

To determine whether sucrase activity increased more when sucrose concentration increased from 2.5 to 7.5 g/l or from 22.5 to 27.5 g/l, we would need specific data on the rate of sucrase activity at these different concentrations. It's possible that the increase from 2.5 to 7.5 g/l was greater if this is in the ascending portion of the enzyme activity curve and the sucrase was not yet saturated with sucrose. Conversely, the increase from 22.5 to 27.5 could be lesser if the sucrase is near or at saturation point.

1. What is the proper order of succession?A. climax community- pioneer species-primary succession- secondary succession

B. pioneer species-primary succession-secondary succession-climax community

(I WILL MARK BRAINLEST )! or however you spell it !!

Answers

B!! Hope this helps!!

The answer fam is......... B. pioneer species-primary succession-secondary succession-climax community

"Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support simple plants such as grasses. These grasses further modify the soil, which is then colonized by other types of plants. Each successive stage modifies the habitat by altering the amount of shade and the composition of the soil. The final stage of succession is a climax community"
