Increasing the volume of air that reaches the alveoli and takes part in gas exchange will cause blood pH to:
Karolina [17]

Answer:

B. increase, because the partial pressure of CO2 in the blood will decrease.

Explanation:

The presence of carbon dioxide gas in blood imparts H+ ions due to its reaction with H2O and thereby, lowers down the blood pH.

When more air reaches alveoli, the rate of gaseous exchange is increased. More of the carbon dioxide is removed from the blood and is released out of the body via exhalation.

Removal of carbon dioxide from blood would increase the pH of the blood since the partial pressure of CO2 in the blood would decrease.

How to find the formula for the nth term​
snow_tiger [21]
“The nth term of the following types of sequences can be found out using the following Formulas:

1.Arithmetic Progression(AP) : here, the consecutive terms differ by a common difference (d).

tn= a+(n-1)d

Where,

a= is the first term of the sequence,

n= nth term

d= common difference

2. Geometric Progression(GP):

Here, the consequtive terms differ by a common ratio (r).

Tn= ar^(n-1)

where,

a = first term

r = common ratio

tn= nth term

3.Harmonic Progression (H.P):

It is the reciprocal of AP.

To find nth term of a HP, first convert it into AP and then apply the tn formula for the sequence and take the reciprocal of the obtained tn again.

Hope the answer helps you!!”

vampirchik [111]

Answer:

A rock is a collection of minerals. In a cooling lava, mineral crystals do not have time to form and are very small. The chemical composition will be the same as if the magma cooled slowly. Existing rocks may be heated enough so that the molecules are released from their structure and can move around.

mixer [17]

 Answer: Spermatogenesis begins at birth and continues throughout a man's life.

The process in which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis is known as Spermatogenesis. Thus, the process of spermatogenesis start with mitotic division of the stem cells that is located close to the basement membrane of the tubules. However, a mature male gametes known as sperm but it is commonly known as spermatozoa.
