Please help. I'm a little confused.

Answer:

A mutation can occur when mistakes are made during DNA replication.

Explanation:

Numerous factors may result in mutations. Some mutations appear to occur on their own, without any environmental factor. They can happen when transcription or replication errors are created in DNA.

The alteration or modification of a person's nucleic acid or DNA sequence is known as a mutation.

This is a normal process that happens because mutagens lead to mutation. Additionally, for certain objectives, man-made mutations can be created to change the gene sequences.

There are many different kinds of mutations, including chromosomal mutations that change the structure of chromosomes and somatic mutations that impact body cells.

Therefore, mutagens, which may be both environmental and non-environmental, can trigger the mutation in DNA.

Recombination Occurs During the Prolonged Prophase of Meiosis I. Prophase I is the longest and arguably most important segment of meiosis, because recombination occurs during this interval. For many years, cytologists have divided prophase I into multiple segments, based upon the appearance of the meiotic chromosomes.

The one that makes up the highest percentage of soil composition is mineral matter. The correct option is A.

In soil science, a soil type is a taxonomic unit. A distinct soil type is formed by all soils that share a specific set of well-defined properties.

Soil type is a technical term for soil classification, which is the science of systematic categorization of soils. Every soil on the planet belongs to a specific soil type.

The composition of the soil is an important aspect of nutrient management. Soil water is what readily provides nutrients for plant uptake, whereas soil minerals and organic matter hold and store nutrients.

A typical soil contains about 45% mineral matter, 5% organic matter, 20-30% water, and 20-30% air. These percentages are, at best, broad strokes.

Thus, the correct option is A.

Answer:

As many as 30 thousand fur seals become entangled in lost or discarded fishing nets or cargo straps each year.

Explanation:

Human activities cause many damages to marine mammals in general. One of these activities is fishery. The nests are intercepting the migratory routes of animals or are floating free in the sea after being discarded. They are extremely strong, so whenever animals get stuck on them, they might carry them for months or years, affecting their diving, foraging, feeding, and reproductive behavior. These nets might hurt the animals´ skin, producing a wound that will probably get infected.

A few years ago, at least 50,000 northern fur seals died per year after getting stuck in fishing nets. The populations of these animals decreased sharply, affecting their reproductive and growth rates. In the present, due to the decrease in their population size, the number of dead animals is around 30,000 per year. This reduction in death is only because there are much fewer animals every year.

protection

Explanation:

The "fat" around the organs is called the "visceral adipose tissue." Its primary function is to "protect" the organs it encloses from injury. It also keeps the person warm especially when exposed to cold environments. Besides this, it also serves as a storage area for your calories in the body. Fat is not completely harmful as most people think.

This is the reason why it is not good to lose so much weight or become too skinny because losing some fat may be harmful to your organ's protection and heat regulation.

There is an increase in density and a corresponding increase in the temperature of the fluid

Explanation:

The temperature and density changes occur in a fluid or gas material that cause convection to occur include increase in density and a corresponding increase in the temperature of the fluid.

This is because convection involves the movement of fluids from a hotter area to a colder area and hot fluids usually have a lower density.

The impact that infectious agents in one's surroundings can have on the health of an individual is they can produce histamine and prevent body cells from reproducing.

Histamine is an important chemical that has a role in a number of different bodily processes. It stimulates gastric acid secretion, plays a role in inflammation, dilates blood vessels, affects muscle contractions.

Histamine is a central mediator released from mast cells through allergic reactions. Histamine plays a role in airway obstruction via smooth muscle contraction, bronchial secretion, and airway mucosal edema.

Histamine regulates a plethora of pathophysiological and physiological processes, such as secretion of gastric acid, inflammation, and the regulation of vasodilatation and bronchoconstriction.

The two ways to increase the energy of a wave are increase the amplitude and increase the frequency. The correct option is B.

A wave is a propagating dynamic disturbance of one or more quantities in physics, mathematics, and related fields.

Periodic waves occur when quantities oscillate repeatedly about an equilibrium value at some frequency.

The amplitude and frequency of a wave are related in such a way that they are inversely proportional. With increasing frequency, the amplitude decreases. As the frequency decreases, the amplitude increases.

The amount of energy in a wave is determined by its height, wavelength, and the distance over which it breaks.

When equal wavelengths are used, a wave with a larger amplitude will release more energy when it returns to sea level than a wave with a smaller amplitude.

Thus, the correct option is B.
