Answer:

Answer: The Environment.

Environmental factors, such as diet, medicines, or exposure to toxins, can change how genes are expressed.

Gene expression is the process through which a gene's information is used to create a functioning gene product, allowing it to produce end products like proteins or non-coding RNA and ultimately have an impact on phenotypes.

Expressivity can be impacted by a number of elements, such as genetic make-up, exposure to dangerous substances, other environmental effects, and age. Penetrance and expressivity both have a range: People who carry the gene may or may not exhibit the trait, and when they do, the trait's expression can take many different forms.

B. Immune and circulatory systems interact with the integumentary system to close the wound.

The integumentary system is the body system that protects the body from damage and disease, and helps regulate body temperature. It includes the skin, hair, nails, and sweat and oil glands.

The skin is the largest organ of the body and serves as a barrier against physical, chemical, and biological agents. Hair and nails provide protection and support, while sweat and oil glands help regulate body temperature and moisturize the skin. Additionally, the integumentary system plays a role in regulating the body's water balance, storing vitamins, and sensing touch and temperature.

Answer:

because of inefficiency

Explanation:

The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers. ... Because of this inefficiency, there is only enough food for a few top level consumers, but there is lots of food for herbivores lower down on the food chain. There are fewer consumers than producers.

Answer: option B.

B)Mating is random with no selection occurring

Explanation:

This will cause change in allele frequency because it's a genetic drift which is the change in the frequency gene variant that is common in a population due to random sampling or random mating. When this occur it lead to a change in percentage or incidence of gene variant in a population since there is random sampling without any selection.

Mating is random with no selection occurring, which would change the allele frequencies of a population.

Natural selection can drive microevolution, or a difference in allele frequencies over time, with fitness-increasing alleles becoming more common in the population over generations.

Thus, option"B" mating is random with no selection occurring.

Answer:

glucose and oxygen

Explanation:

Answer:

Im pretty sure it's A

[tex] \huge \purple{\tt{Answer:}} [/tex]

glucose

The molecule here that contains only carbon, hydrogen, and oxygen is Glucose. So the correct option is B.

Glucose is a monosaccharide or simple sugar. It is a kind of sugar found in honey and fruits. Glucose is the major sugar present in our body.

It is the main source of cellular energy utilized in the process of cellular respiration. Thus, it helps in proper cell functioning and metabolism.

Starch molecules are composed of various monomers of glucose. They are the polysaccharides of glucose. The structural formula for glucose is C₆H₁₂O₆. This means that glucose is only composed of carbon hydrogen and oxygen atoms.

Glucose is a type of Carbohydrate but there are other kinds of carbohydrates that contain elements like nitrogen and sulfur. Proteins and nucleic acids also contain other elements like phosphate, nitrogen, and sulfur.

Thus only glucose is composed of oxygen, carbon, and hydrogen.

Therefore the correct option is B.

Answer:

true

Explanation:

False. At the freezing point, the particles in an object have some kinetic energy.

False. On the Celsius temperature scale, there are negative numbers.

True. The more particles an object has at a given temperature, the more thermal energy it has.

False. Object A is much larger than Object B, but both are made of the same material. If both objects are at the same temperature, the thermal energy of Object A is not the same as the thermal energy of Object B.

False. When heat is absorbed by an object, the speed of the particles in the object is changed.

Explanation:

So from this, we can conclude that :

At the freezing point, the particles in an object have some kinetic energy.

On the Celsius temperature scale, there are negative numbers.

The more particles an object has at a given temperature, the more thermal energy it has.

Object A is much larger than Object B, but both are made of the same material. If both objects are at the same temperature, the thermal energy of Object A is not the same as the thermal energy of Object B.

When heat is absorbed by an object, the speed of the particles in the object is changed.
