Studentka2010 [4]3 years ago
5 0

Answer:

The minimum difference is already the value of 1

Explanation:

When the pH is not balanced between the extracellular and intracellular environment, the cell could go into shock, that is why in the face of the minimal differences in pH between the internal or external environment, the proton pump is activated, this is how the hydrogen ion or positively charged protons cross the membrane and indirectly generate ATP molecules.

Assume that the mother's genotype is AZ/az, and the father's genotype is Az/aZ, and the recombination rate is 10%. What are the
attashe74 [19]

Answer:

0.45 from mom and 0.05 from dad.

Explanation:

The recombinant progeny might occur due to the crossing over at the time of meiosis in which the exchange of chromosomes occur in the homologous chromosomes of non sister chromatids.

The progeny receives half of their chromosome from the mother and half from the father. The mother 50% AZ and 50% az chromosomes respectively. The 10% recombination has occured due to which the mother chromosomes is reduce upto 45%. The recombinant  10% will be aZ and Az and has 5% frequency. Mom has the ability of az chromosomes is 0.45 %. The father has the genotype 50% Az and 50% aZ. The 10% recombination has occured due to which the father chromosomes is reduce upto 45%. The recombinant will be az and AZ with 5% frequency. So, father has az with 0.05 % probability.

Thus, the answer is 0.45 from mom and 0.05 from dad.

What tropic hormone stimulates cortisol from the adrenal gland?
zhuklara [117]

Answer:

c) adrenocorticotropic hormone (ACTH).

Explanation:

A tropic hormone is defined as the hormone which is secreted from one gland and acts on another gland. ACTH is released by anterior portion of our pituitary gland during the condition of biological stress. After it is released, it acts on adrenal gland so that adrenal gland could secrete another hormone named as cortisol (steroid hormone). In response to stress, cortisol increases blood sugar level, elevates brain's use of glucose etc. so as to counter stressful situation.

Apart from this cortisol also helps in regulating our metabolism, reduces inflammation and controls salt and water balance.
