5. Explain how selection might be different if there were brown grasshoppers in
Semenov [28]

Answer:

Explanation:

Selection breeding is use to identify individual with good physical characteristics that can be used as parent in next generation. Brown, yellow, green grasshoppers are the distinct phenotypic characteristics of an individual hence selection will be individual base. Such that brown individual will be selected, green selected seperated and yellow will also selected. The organism that shows the best fits are often been selected depending on the objects of the selection

consider the following at 8 p.m. a diabetic is found to have a blood pH of 7.33 is Brian tells his diaphragm to contract more fr
Radda [10]

Answer:

Considering that homeostasis is restored in the patient, his blood pH range would return to normal levels (7.35-7.45), and his hydrogen ion concentration in the blood would normalize. The effect of normalizing the body by getting rid of excess hydrogen ions is achieved by concentrating these ions into the urine for expulsion, therefore increasing the pH levels of urine.

Explanation:

Acidosis is the condition wherein excessive acid build-up within the body causes the blood pH to become lower than normal (normal pH range 7.35-7.45). This may be due to an excessive loss of bicarbonate in the blood, also known as metabolic acidosis, or due to an impairment in the elimination of carbon dioxide in the blood from poor lung function, also known as respiratory acidosis. The body's natural response to acidosis is to increase the breathing rate to eliminate carbon dioxide in the blood, restoring the natural pH of the body.

In people with diabetes mellitus type I, the lack of insulin causes cells to breakdown fat aside from glucose as an energy source. This process produces ketones as a metabolic by-product for energy but also causes the body to be acidic. This is known as diabetic ketoacidosis.

The number of bacteria in a certain population is predicted to increase according to a continuous exponential growth model, at a
Brilliant_brown [7]

The given question is incomplete. The complete question is as follows;

The number of bacteria in a certain population is predicted to increase according to a continuous exponential growth model, at a relative rate of 16% per hour. Suppose that a sample culture has an initial population of 71 bacteria. Find the predicted population after three hours Do not round any intermediate computations, and round your answer to the nearest tenth bacteria .

Answer:

114.7

Explanation:

A (t) represent the population of the bacteria at the time t.

Since, the population grows exponentially, the population can be calculated as follows:

A (t) = Ao ×  e^{kt}

A (t) is teh final population, Ao is the initial population, e is the exponential, k is rate and t is time.

A (t) = 71  × e^{0.16\times t}

For t = 3 hours

A (t) = 71 × e^{0.16\times 3}

A (t) = 114.7.

The population of bacteria after 3 hours is 114.7.
