Answer:
FIRST ONE
Explanation:
Reproduction. Pink salmon in their native range have a strict two year life cycle, thus odd and even-year populations do not interbreed. In the state of Washington, Pink salmon runs occur on odd years. Adult pink salmon enter spawning streams from the ocean, usually returning to the stream where they originated.

Answers
A biome that has a large amount of rainfall, high temperature, and poor soil is a Tropical rain forests. So, the correct option is (C).
What are Tropical rain forests?Tropical rainforests are defined as rainforests that occur in areas of tropical rainforest climate with no dry season when all months have an average rainfall of at least 60 mm. It can also be called lowland equatorial evergreen rainforest.
The largest rainforests exist in the Amazon in Brazil (South America), the Democratic Republic of the Congo (Africa) and Indonesia (South East Asia). They are also found in Hawaii and on islands in the Pacific and Caribbean.
Vegetation is characterized by large trees and dense vegetation on the ground surface, but due to the high amount of rainfall and the rapid acquisition of nutrients from the decomposition of organic matter by plants, soils in tropical rainforests are generally nutrient deficient and non-porous.
Thus, a biome that has a large amount of rainfall, high temperature, and poor soil is a Tropical rain forests. So, the correct option is (C).

Gene expression is influenced by many factors. Which of the following is a factor in gene
expression?
Answers
Answer:
Answer: The Environment.
Environmental factors, such as diet, medicines, or exposure to toxins, can change how genes are expressed.
What are factors affecting gene expression?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.

Why is biomass a better alternative to oil?
A. Biomass does not release carbon dioxide.
B. Biomass creates radioactive waste.
C. Biomass does not need to be burned.
D. Biomass is a renewable resource.
Answers
Answer:
D
Explanation:
Biomass does release CO2 (when burned) because it is organic - contains carbon compounds.
Biomass does not create radioactive waste.
Biomass is renewable because it comes from plants, whereas oil takes millions of years to make, so it is non-renewable.
The correct option is (d) Biomass is a renewable resource.
Because it can be created from sources that are renewable and can be continuously replenished, such as garbage and plants, bioenergy, also known as energy obtained from biomass, is a sustainable substitute for fossil fuels. And cut down on our gasoline supply, compromising our national security.Some of the advantages of biomass energy are:-A constant and accessible renewable energy source is biomass.It has no carbon emissions.It lessens our dependency on fossil fuels.Is more affordable than fossil fuels.The generation of biomass gives manufacturers a new source of income.Fewer trash items in landfills.Learn more about advantages of biomass energy brainly.com/question/11381203

To stop a wound from bleeding, platelets in the blood clump together to form a blood clot. The clot dries into a hard scab to protect the wounded area. Underneath the scab, the blood supplies nutrients and oxygen that help new skin cells form. As the skin regenerates, the wound closes.
Which body systems interact with the integumentary system to close the wound?
A. Circulatory and reproductive
B. Immune and circulatory
C. Reproductive and immune
D. Digestive and endocrine
Answers
B. Immune and circulatory systems interact with the integumentary system to close the wound.
What is integumentary system?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.

Answers
[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.
What is glucose?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.

Beavers are able to adapt to the changing conditions of all four seasons. Which of the following would threaten the survival of beavers?
A. hot temperature in July
B. freezing rain in
December
C. forest fire in October
D. snow in January
Answers
Answer:
C
Explanation:
The question says that beavers are able to adapt to changin questions in each season, so we know that snow in winter, or heat in summer won't bother them. These types of variations in weather are what the beaver is used to. This would eliminate A (July is in summer, so the beavers would expect heat), B (December is in winter, so the beavers would expect freezing conditions), and D (January is in winter, so the beavers expect the snow). That leaves us with C. Fires are not a typical condition for a season- fires aren't expected every fall. Therefore, when there is a fire, beavers will not know what to do. Hope this helps, and feel free to ask me for more clarification!

A)Lack of mutation in the DNA
B)Mating is random with no selection occurring
C)A population on an island remains isolated and no one leaves or moves on the island
D) All of the answer choices would change allele frequencies of a population.
Answers
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.
What would increase the allele frequency in 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.
