Goiters may occur due to iodine insufficiency, but other causes are possible. Which of the following would NOT tend to result in increased size of the thyroid gland?
A. High levels of thyrotropin releasing hormone.
B. High levels of thyroid stimulating hormone.
C. High levels of thyroxin and triiodothyronine.
D. All of the above would tend to increase the size of the thyroid gland.
E. None of the above would tend to increase the size of the thyroid gland.

Goiters May Occur Due To Iodine Insufficiency, But Other Causes Are Possible. Which Of The Following

Answers

Answer 1

Answer:

Option A

Explanation:

Thyroid is primarily caused by lack of iodine but there are other reasons as well that lead to increased size of the thyroid gland. Some of these reason is

a) over- or underproduction of thyroid hormones

b) Nodules in the glans

Some times, due to overstimulation immune system itself attack the thyroid gland thereby producing excess thyroxine and hence causing  the thyroid to swell

Thus, Option A is correct

Draw the structures of deoxyribose, guanine, and phosphate and rate their relative solubilities in water (most soluble to least soluble). How are these solubilities consistent with the three-dimensional structure of double-stranded DNA?

Answers

Answer:

The solubilities in water of the three molecules from most to least soluble is in the following order: phosphate > deoxyribose > guanine.

Explanation:

The phosphate group is the most water-soluble due to it being very much negatively charged .

The deoxyribose which has several hydroxyl groups, is the next most water-soluble molecule.

The guanine molecule is hydrophobic, therefore, it is the least soluble in water.

A DNA molecule is composed of the three molecules: deoxyribose sugar, a phosphate group and a nitrogenous base which could either be a purine or a pyrimidine.

The three dimensional structure of DNA is such that the the phosphate groups and deodyribose sugars form the backbone of the structure on the outside of the DNA double helix where they are exposed to the aqueous environment of the nucleus. On the other hand, the hydrophobic nitrogeneous bases are located in the interior of the double helix where they are excluded from excludedthe aqueous environment of the nuclues. This structural arrangement is in accordance with the solubility of the molecules where the water-soluble phosphates and sugars are exposed to water while the water-insoluble bases are away from water.

Explanation:

The following statements concerning the karyotype in the diagram is true - The diagram illustrates the results of nondisjunction during gamete formation.

Karyotype

Karyotype refers to the number and appearance of chromosomes present within the nucleus of a eukaryotic cell. It is illustrated as a diagram such as given in the question.

There is no Down's syndrome as the karyotype demonstrates a normal pair of chromosome 21.  In this karyotype, there is an extra X-chromosome that depicts non-disjunction during either oogenesis or spermatogenesis (gamete formation) in the parents leading to the 23rd trisomy.

How do divisions in the geologic time scale differ from the way we organize time using a clock?

Answers

Explanation:

The Earth's geologic past is divided into hierarchical time periods. This hierarchy comprises eons, eras, times, epochs, and ages, from largest to smallest. The Cenozoic, Mesozoic, and Paleozoic Periods are the three main divisions of the Phanerozoic.

The geological timescale is the official earth clock and differs from the way we organize time using a clock, as the planet's time is too long for us to use measures of hours.

Geologic timescale

Planet Earth is about 4.5 billion years old. To better understand its history, scientists divide geologic time into five levels of classification, called chronostratigraphic units:

EonsErasPeriodsEpochsand ages.

Eons are large and indeterminate spans of time and are divided into four classifications:

Phanerozoic (last 542 million years)ProterozoicArcheanand Hadean.

Of them, only the Hadean is not divided into ages. The ages are characterized according to the different positions of continents, oceans and their living beings. Within the ages are divided in the periods. Epochs, in turn, are divisions within periods and are divided into ages. According to the researchers, we currently live in the Quaternary period of the Cenozoic era.

To get a rough idea of ​​how much the existence of the human being is a mere recent episode in Earth's geological time, we use some analogies. For example, if the entire history of the planet were summarized in the twenty-four hours of a day, the existence of humanity would have occurred in the last three seconds of that same day.

Understanding the dimension of geological time and its scales of measurement becomes a fascinating mental exercise to better understand the role of man in relation to this temporality and his role as heir of all the transformations that have taken place in terrestrial space throughout the geological ages.

why groups of animals are found on some islands but not others?

Answers

Answer:

Wilson has created the theory of the biogeographic nature of the island, which predicts that the number of species on the island depends on the balance between colonization, the evolution of the novel island species, and extinction.

Explanation:

A new DNA sequence containing 596 species of terrestrial birds from 41 island chains (archipelagos) around the world has been assembled by the researchers. The data combined sample data from their own field visits, research, and field samples from GeneBank colleagues. This information was utilized to build and employ a dynamic model that predicted international relationships that regulate biodiversity variation in their novel analysis approaches. In that, they confirmed two main components of MacArthur and Wilson's initial biogeography theory on the island.

The understanding of biodiversity on the island is important to conservation but also has implications beyond that – when imposing barriers to species dispersal it could enable us to assess better the effects of human activities, and it can contribute to a wider understanding of biodiversity around the globe.

It is an attraction that exists between all objects, everywhere in the universe. ... where G is called the Gravitational Constant.

How could gravity affect the water cycle?

ans:It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. ... Gravity pulls denser air and water downward, forcing less dense air and water to move upward.

What is homeostasis?" A state of balance among all the body systems needed for the body to survive and function correctly."How respiratory system maintain homeostasis?Respiratory system helps to remove carbon dioxide and excess heat from our body and maintains our blood pH.During respiration, carbon dioxide reacts with water to form a carbonic acid in presence of enzyme carbonic anhydrase. It further dissociates into bicarbonate and H+ ions. This reaction are in equilibriumWhen the level of H+ ions increases, the pH level increases. This will signal respiratory system to release more carbon dioxide. This will result in formation of carbon dioxide and decrease level of H+ ions which will result in increase blood pH.When we breathe out, the moisture from the tissue are also expelled.

Hence, the respiratory system helps release unwanted heat and water from the body.
