Answer:

D. Agronomist

Explanation:

Agronomists are professionals that study how to make soils more productive (in terms of food) around the world. Soil pH is an index that calculates the acidity/alkalinity of the soil, which is indicated on a 14-point scale (pH equal to 7 = neutral; pH below 7 = acidic,  pH higher than 7 = alkaline). In this regard, it is well known that the pH of the soils drastically affects plant development, and thereby a proper soil pH is fundamental to ensure optimal plant growth (required for nutrient intake). For this purpose, agronomists are in charge of studying and researching the pH of the soils in order to increase crop yields. Nowadays, the pH of the soils can be easily measured by digital soil pH pocket testers that utilize a pH electrode in order to calculate the pH value.

Explanation:

Let's denote the width of the park as "w" miles. According to the given information, the length of the park is 1/2 miles and the area of the park is 6/8 square miles.

The area of a rectangle is given by the formula: Area = Length × Width

Given that the length of the park is 1/2 miles and the area of the park is 6/8 square miles, we can set up the following equation:

1/2 * w = 6/8

To solve for "w", we can multiply both sides of the equation by 2 (to eliminate the fraction):

2 * (1/2 * w) = 2 * (6/8)

w = 12/8

Now, we can simplify the fraction w = 12/8:

w = (12 ÷ 4) / (8 ÷ 4)

w = 3/2

So, the width of the park is 3/2 miles.

Answer: A diverse population of bacteria that is treated repeatedly with the same antibiotic and not all of them die will eventually lead to the emergence of antibiotic-resistant bacteria that will thrive and become dominant. The population's antibiotic resistance level before being exposed to the antibiotic was low or non-existent. The "good" bacteria will die while the antibiotic-resistant bacteria will survive and reproduce. After antibiotic treatment, the population's antibiotic resistance level will be higher than before.

Explanation:

Answer:

The correct answer is - they may not be able to survive at such a temperature.

Explanation:

A Cold front is a weather change when a cooler air mass moves into warmer air that leads to a sudden drop in temperature following by the cyclone, heavy rainfall and hail.

These sudden changes and heavy rain with storms and cyclones can limit the population growth of newborn offspring as they may not able to survive in such a sudden temperature drop.

Answer: Exceeding threshold depolarization at the trigger zone decreases the likelihood of generation of an action potential.

Explanation:

Exceeding threshold depolarization at the trigger zone decreases the likelihood of the generation of an action potential.

Excessive depolarization at the trigger zone reduces the likelihood of an action potential being generated. The amplitude of the action potential decreases with distance. The number of action potentials increases as the frequency of stimulation to the trigger zone increases.

Because the potassium channels within the cell membrane are delayed, any additional sodium entry activates an increasing number of voltage-gated sodium channels. Depolarization above the threshold causes an increase in Na conductance sufficient for inward sodium movement to instantly swamp outward potassium movement.

Therefore, Excessive depolarization at the trigger zone reduces the likelihood of an action potential being generated.

The lake's pH has become acidic; in 1989, it was 6.7; by 1996, it had dropped to 5.1. This shows that the increase in the acidity which has several bad impacts on the lake water ecosystem and its community.

The freshwater ecosystem differs from the oceanic saltwater ecosystem in that freshwater contains phytoplankton, edible fish, and so on. The fresh water has a normal pH, but the pH decreases and induces acidity when the water is polluted with different chemicals, such as nitrogen oxide, sulfur dioxide, etc.

When acid rain happens due to man-made pollution, this further adds acidity to the fresh water, and as a result, the species that live in the lake are not able to live and breathe properly due to a lack of oxygen. The acidity in the table increased year after year from 1989 to 1996.

Hence, the acidity of the lake increased and the pH decreased in these years, from 1989 to 1996.

If a dialysis tubing lost water, it is likely because it was placed in a hypertonic solution, where the concentration of solutes outside the tubing was higher than inside.

Dialysis tubing is a semi-permeable membrane that allows the passage of small molecules but prevents the passage of larger ones. When placed in a solution, the movement of water and other molecules across the membrane depends on the concentration of solutes on either side of the membrane.

If the concentration of solutes outside the tubing is higher than inside, the solution is hypertonic to the inside of the tubing. In this case, water will move out of the tubing through osmosis, causing the tubing to lose water and shrink.

On the other hand, if the concentration of solutes outside the tubing is lower than inside, the solution is hypotonic to the inside of the tubing. In this case, water will move into the tubing through osmosis, causing the tubing to gain water and expand.

Therefore, if the dialysis tubing lost water, it is likely because it was placed in a hypertonic solution, where the concentration of solutes outside the tubing was higher than inside. This caused water to move out of the tubing and into the solution, leading to a decrease in the volume of the tubing.

Nuclear division is the process of dividing the nucleus. Nuclear division is the process through which the nucleus of a cell splits, producing two daughter nuclei, each with a full set of chromosomes. Mitosis and meiosis are the two basic kinds of nuclear division.

A mitosis is a form of nuclear division that happens in somatic cells and is crucial for tissue development and repair. Mitosis occurs when the nucleus' chromosomes are duplicated, and the cell splits into two identical daughter cells, each with the same number of chromosomes as the parent cell.

Meiosis is a type of nuclear division that happens in reproductive cells and is responsible for sperm and egg cell production. The nucleus' chromosomes are duplicated during meiosis, and the cell divides into four non-identical daughter cells, each having half the number of chromosomes as the parent cell.

Mitosis and meiosis are both required for living creatures to grow, repair, and reproduce.

DNA and RNA have similarities in their nucleotide composition and involvement in genetic processes. However, they differ in their sugar type, strandedness, and specific functions in protein synthesis. Understanding these similarities and differences is crucial for comprehending the fundamental mechanisms of genetics and cellular processes.

RNA and DNA are both nucleic acids that play essential roles in genetic information and protein synthesis. However, they differ in various aspects.

DNA, or deoxyribonucleic acid, is a double-stranded molecule composed of nucleotides. It contains the sugar deoxyribose and the nitrogenous bases adenine (A), cytosine (C), guanine (G), and thymine (T). DNA carries the genetic code and serves as the hereditary material in most organisms.

On the other hand, RNA, or ribonucleic acid, is typically single-stranded and contains the sugar ribose. RNA also consists of nucleotides, but it uses uracil (U) instead of thymine as a nitrogenous base. RNA has several forms, including messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). Each form has specific roles in protein synthesis.

In terms of function, DNA stores and transmits genetic information, while RNA helps translate that information into proteins. DNA is primarily located in the nucleus of cells, while RNA is found in both the nucleus and cytoplasm.
