In the box provided explain why living organisms contain more hydrogen atoms than any other atoms yet 65% of a typical organisms mass is oxygen

Answers

Answer 1

Answer:

The prime reason for this is that an atom of oxygen comprises sixteen times more mass in comparison to a hydrogen atom.

Explanation:

This means that A orginasim will appear to contain more oxygen, but the size diffrence will mean that there will be more hydrogen, just of a smaller size with less mass, thus making up a lesser part of the organism in terms of mass, but the majority on the molecular level.

Answer 2

Answer:

Reason 1: The mass of Oxygen is 16 times that of Hydrogen. Hydrogen takes 16 atoms to equal the mass of 1 Oxygen atom.

Reason 2: A large portion of an organism’s mass is in the form of water. Water contains two hydrogen atoms and one oxygen atom.

Answer:

homeostasis

Explanation:

Homeostasis is the biological process by which living organisms maintain a stable internal environmetal condition despite changes in their external environment. Homeostasis is an important phenomenon for the optimal functioning of any living organism.

A vivid example of homeostatic process is the regulation of temperature in humans or some animals. Self-r regulating mechanisms help keep their temperature at a stable state irrespective of temperature changes in the external environment i.e. hot or cold external conditions. The steady state of internal temperature is very important for some physiological processes in living systems.

Explanation:

Sabita is a mother in Nepal. She lives in poverty in the Western part of the country with her two children. Everyone in her family has some degree of malnutrition or nutrient deficiency. Match each of the following deficiency diseases with its corresponding nutrient.

a. Sabita is blind from a diet devoid of fortified milk, animal products, or dark yellow and orange fruits and vegetables.
b. Sabita has an enlarged thyroid gland due to a dependence on unfortified salt.

Nutrient:
1. Iron
2. Vitamin A
3. Vitamin D
4. Iodine

Answers

Answer:

a. Sabita is blind from a diet devoid of fortified milk, animal products, or dark yellow and orange fruits and vegetables. - Vitamin A

Sabita is suffering from Vitamin A deficiency. A lack of Vitamin A usually shows itself with night blindness but can cause complete blindness if not acted upon quickly.

Vitamin A deficiency is quite common in developing or poorer nations such as the area Sabita is located and usually attacks children of women in their reproductive stage. Sources of vitamin A include; fortified milk, animal products and fruits and vegetables.

b.  Sabita has an enlarged thyroid gland due to a dependence on unfortified salt. - Iodine

Iodine deficiency leads to an abnormal enlargement of the thyroid gland leading to a condition known as Goiter which presents itself as a big bulge in a person's neck. Iodine is usually placed in fortified salt along with iron to reduce iodine deficiency so Sabita's dependence on unfortified salt is robbing her of a great source of Iodine.

The condition in which the body is deprived of minerals, vitamins and other macro and micronutrients are called malnutrition.

The correct matches and their explanation are as follows:

a. The correct answer is:

Option 2. Vitamin A

Sabita is blind from meals deficient in fortified milk, animal products, fruits and vegetables due to Vitamin A deficiency.

Night blindness is a common symptom of a Vitamin A deficiency.

It is most common in developing regions due to the lack of proper meals. The best source of vitamin A is milk, fruits and animal products like eggs.

b. The correct answer is:

Option 4. Iodine

Sabita has a swollen thyroid gland due to habituation on unfortified salt deficient in Iodine.

Iodine deficient diet causes thyroid gland enlargement a disease called Goiter. This type of disease also affects glucose metabolism and weight.

An area classified as a temperate deciduous forest begins to experience a lack of rainfall that lasts for many years. Given enough time, if the area continues to experience a lack of rainfall, it will eventually become:__________a. savanna.b. temperate rainforest.c. shrubland, grassland, or woodland.d. taiga.

Answers

Answer:

Savanna

Explanation:

Lack of rainfall over a period of time may convert a temperate deciduous forest into a Savanna.

Grasslands are characterized by a domination of grasses rather than large shrubs or trees. Savanna is a grassland with a few scattered individual trees. Savannas are always found in areas that are quite hot. The annual rainfall in a typical savanna may range from about 76.2-101.6 cm. Some savanna regions may receive as low as 15.24 cm -25.4 cm of rain in a year, followed by a long period of drought when fires can occur.

population of squirrels live together in forest an event occurred that caused the population to diverge into two different species over a long period of time which of the following is most likely the event occurred

Answers

A natural disaster.

Explanation:

A natural disaster would most likely have occurred to have the population of squirrels completely diverge from each other in order for them to become two separate species.

If a tornado, flood, earthquake, or another type of a natural disaster were to happen, it may have caused drastic damage to the ecosystem and environment of the squirrels. This would most likely cause the squirrels to split up, or diverge from each other and go to separate places in search of a new home.

Over time, these squirrels will reproduce with their own group. Each new group of squirrels, as they are both in different environments now, will have different adaptations from each other. This will eventually make it so they will never be able to reproduce with each other again if they were to meet, as they are now completely different species of squirrel.

the couple about their neonate's condition?

Answers

Answer:

osteogenesis imperfecta is an inherited genetic disease that mainly affects the bones.  

Explanation:

Osteogenesis imperfecta is an inherited genetic disease associated with alterations in collagen synthesis, which have been shown to increase the risk to suffer bone fractures. This genetic disorder is characterized by different health problems including, among others, fragile bones, reduced skeletal mass, skin hyperlaxity, malformations in the central nervous system, etc. Clinically, osteogenesis imperfecta must be managed by an interdisciplinary medical team, since patients may present a clinical picture ranging from mild to lethal. In the first place, it is imperative to provide health care to avoid fractures, exercises to maintain muscle mass, exercise to improve motor skills, skincare by specialized dermatologists, etc.

The disease 'osteogenesis imperfecta' is caused by the neonate inheriting it

from either of the parent because it's a genetic disorder. The health care

provider should teach the parent about how to prevent the effect of having

such disease such as bone fractures.

Osteogenesis imperfecta is a genetic disorder inherited by offspring from

their parent. The disease involves individuals having very  brittle bones which are easily broken. The nurse should teach the parent to adopt bone strengthening steps such as adequate calcium intake and physiotherapy.

Answers

Answer:

exocarpo  is synonymous with exocarp

endocarpo is synonymous with endocarp

mesocarpo is synonymous with mesocarp

semilla is synonymous with seed

Explanation:

In phase one, the plant's ovary begins to grow abruptly, this is where the embryo and endosperm affect their size, but if this ovarian growth is interrupted by an external factor, it determines the size of the future.

Then, the embryo and the endosperm could grow and undergo a process called sclerification, which is the hardening of the interior of the fruit, that is to say, the future formation of the seed or vulgarly called "pit". .

After this, the mesocarp, which is what is called the fleshy body or subglobose edible drupe, begins to grow.

The growth of the mesocarp is what gives the volume, weight and body to the fruit, so that after maturation it exceeds the strength of the branch and it falls from the tree.

A) The repressor will no longer bind to the operator.
B) The repressor will no longer bind to the inducer.
C) The lac operon will be expressed continuously.
D) The lac operon will function normally.

Answers

Answer:

D) The lac operon will function normally.

Explanation:

The promoter area can be described as the area that causes the transcription to initiate for a particular gene. Promoters may be near the genes from which they initiate transcription or they may display multiple scenes upstream. The lock operon works normally because the promoter area can still enable transcription on many base pairs. Detects repression promoter and works normally.so correct option is D) The lac operon will function normally.

If a researcher moved the repressor gene of lac I, along with its promoter; the lac operon will function normally. Option D is correct.

Promotor:

It is the genetic sequence that is recognized by the RNA polymerase to start the transcription.

Here, researcher moved the repressor gene of lac I , along with its promoter.

Therefore, transcription starts, it will express the repressor gene also because repressor gene was moved with promotor.

Debt financing has one important advantage that the early Modigliani and Miller (MM) propositions ignored: the interest on business debt is tax deductible. This benefit means that the amount of taxes that a business is required to pay will be reduced by a phenomenon called an interest tax shield, which is a function of the amount of debt in the firm's capital structure and its tax rate. In contrast, the dividends that a corporation pays on its common and preferred shares are not tax deductible.
