An increase in carbon dioxide in the atmosphere will most likely affect a type earth activity called cave formation.

The carbon dioxide (CO2) in the earth atmosphere is increasing as a result of the anthropogenic activities such as deforestation, burning of the fossil fuels.

Carbon dioxide is known to be a greenhouse gas that is released by living organisms as a waste product of cellular respiration.

The carbon dioxide in the atmosphere gets mixed with the rain water which seeps into the soil. This results in the accumulation of carbonates (CO3²-) in the soil as limestone.

The cave of limestone is formed by the groundwater because limestone is a soft material which get easily dissolves in the water.

Explanation:

In DNA, the base pairs adenine (A) always pairs with thymine (T), and cytosine (C) always pairs with guanine (G). Since thymine makes up 28% of the nucleotides in the DNA sample, we can assume that guanine will also make up 28% of the nucleotides.

In DNA, the total percentage of adenine (A) and thymine (T) is equal to the total percentage of cytosine (C) and guanine (G). This is known as Chargaff's rule. Therefore, the percentage of guanine (G) in the sample will also be approximately 28%.

Among the given options, option (c) Estrogen inhibits bone resorption, is the correct answer.

Sex hormones are chemical messengers that are responsible for regulating sexual development, behavior, and physiological processes in humans and animals. The sex hormones include androgens, estrogens, and progesterone in humans.

Testosterone is a male sex hormone that is produced by the Leydig cells in the testicles. It is responsible for the development of male secondary sexual characteristics, such as body hair growth, deepening of the voice, and muscle growth. It also stimulates the production of sperm by the Leydig cells in the seminiferous tubules of the testicles. Therefore, option (a) is the correct expected effect of testosterone.

Estrogen is a female sex hormone that is produced by the ovaries. It is responsible for the development of female secondary sexual characteristics, such as breast development and the widening of the hips. It also stimulates the growth of the endometrial lining of the uterus, which is necessary for the implantation of a fertilized egg. Therefore, option (b) is also the correct expected effect of estrogen.

In addition, estrogen also has a protective effect on bone density. It inhibits the activity of cells that break down bone tissue, which helps to prevent osteoporosis. Therefore, option (c) is an incorrect expected effect of estrogen.

Testosterone also causes the development of male secondary sex characteristics, such as the growth of facial hair, the deepening of the voice, and the enlargement of Adam's apple. Therefore, option (d) is also the correct expected effect of testosterone.

Therefore, all of the given effects of sex hormones are true except that estrogen inhibits bone resorption.

The equilibrium potential for sodium can be calculated using the Nernst equation, which is E = (RT/zF) * ln([Na+]o/[Na+]i).

In this case, [Na+]o is the concentration of sodium in the interstitial fluid (120 mm), [Na+]i is the concentration of sodium inside the cell (12 mm), R is the gas constant (8.314 J/(mol·K)), T is the temperature in Kelvin (37 + 273 = 310 K), z is the charge of sodium ion (1), and F is the Faraday constant (96,485 C/mol). Plugging in the values, we can calculate the equilibrium potential for sodium. The equilibrium potential for sodium, given the concentrations of 12 mm inside the cell and 120 mm in the interstitial fluid at a temperature of 37 degrees C, can be calculated using the Nernst equation. The Nernst equation E = (RT/zF) * ln([Na+]o/[Na+]i) allows us to calculate the equilibrium potential for sodium. Plugging in the values of [Na+]o (120 mm), [Na+]i (12 mm), R (8.314 J/(mol·K)), T (310 K), z (1), and F (96,485 C/mol), we can solve for E. The equilibrium potential for sodium in this case would be approximately -61.5 mV.

Summary: The equilibrium potential for sodium in a cell with a concentration of 12 mm sodium and surrounding interstitial fluid with a concentration of 120 mm sodium, at a temperature of 37 degrees C, is approximately -61.5 mV, as calculated using the Nernst equation.

Explanation:

If blood supply to an arm is cut off, the arm would become ischemic, which means that there would be no blood flow to the tissues in the arm, which could lead to tissue damage or death and after five minutes, the blood in the arm would have decreased oxygen levels, increased carbon dioxide levels, increased acidity, and decreased pH.

The correct option to the given question is option d.

If blood supply to an arm is cut off, the arm would become ischemic. The absence of blood supply means that the cells in the arm would not receive oxygen or nutrients, which are essential for cell function and survival.
After five minutes, if blood in the arm is sampled and analyzed, the following changes would be observed:
Decreased oxygen levels: Since blood is not flowing to the arm, oxygen levels in the blood would decrease. This would lead to hypoxia, which is the condition of not having enough oxygen to meet the body's needs.
Increased carbon dioxide levels: As oxygen levels decrease, carbon dioxide levels in the blood would increase. Carbon dioxide is a waste product of cellular metabolism, and it is normally carried away by the blood to be exhaled by the lungs. If blood flow is cut off to the arm, carbon dioxide would build up in the tissues.
Increased acidity: When cells are deprived of oxygen, they switch to anaerobic metabolism, which produces lactic acid. The accumulation of lactic acid in the tissues would lead to an increase in acidity.
Decreased pH: As a result of the increased acidity, the pH of the blood would decrease. pH is a measure of how acidic or alkaline a substance is. A lower pH indicates higher acidity.thus, correct option is d.

\(NH_{4} ^{+}, NO_{3} ^{-}, CO_{3} ^{2-}\)

Explanation:

A molecule is a chemical species containing at least two chemically-bonded atoms while an ion is a charged chemical species.

Hence, a molecular ion must be a molecule and must carry a charge (positive or negative).

Given the two criteria above, then \(NH_{4} ^{+}, NO_{3} ^{-}, CO_{3} ^{2-}\) are all molecular ions. \(NaCl\), although a molecule, is not a molecular ion because it is not charged.

The following are simple molecular ions NH₄⁺, NO₃⁻, and CO₃²⁻. The correct options are a, c, and d.

Molecular ions are the name given to molecules and elements that are charged either positively or negatively. Many elements participate in chemical reactions and form bonds with each other's atoms. Those elements that have a charge on them are known as molecular ions.

These elements or compounds taking part in bond formation are called ions because when they donate or get electrons, they acquire a charge, positive or negative.

In the following, NH₄⁺, NaCl, NO₃⁻, and CO₃²⁻. All are simple molecules, but NaCl is not considered an ion because it does not contain any charge. So this will not be an ion.

Thus, the options are a. NH₄⁺, c. NO₃⁻, and d. CO₃²⁻.
