i think it’s (d) cuz if u try finding the answer by elimination d is the only one that makes sense also water is an abiotic factor so yea i hope it’s d

Two different species of mammals competing for the same water source is an example of two organisms competing for an abiotic factor.

What is abiotic factor?

Abiotic factors refers to non-living physical parts of the environment that affect living organisms as well as the functioning of ecosystems. In the above example, water source is a non-living part of an ecosystem which is required by both organisms.

This leads to competition of two mammals so we can conclude that two different species of mammals competing for the same water source is an example of two organisms competing for an abiotic factor.

The incidence of V. vulnificus infections is increasing, especially in northern parts of the United States, compared to 20 years ago. Can you think of any reason why this might be happening?

Answers

Answer:

The effects of climate change may be associated with the increased incidence of V. vulnificus infection

Explanation:

Vibrio vulnificus is a harmful bacterium that causes a serious disease due to eating contaminated seafood, which is the main cause of seafood-related deaths in the USA. V. vulnificus is naturally present in the flora of coastal waters around the world and this bacterium has been isolated from a variety of seafood (e.g.., fish, oysters, shrimp, etc). Epidemiologic studies have shown that the incidence of V. vulnificus infection has increased dramatically since 1996. During this same period, climate change has been responsible for the increase in salinity and temperature of the coastal waters (i.e., the natural habitat of this bacterium). In consequence, it is reasonable to suppose that the change in climatic conditions may be associated with the increased incidence of V. vulnificus infection.

Compare the reactants and products in the chemical equations below. Which statement best describes the relation between matter and energy?

Answers

Answer and Explanation:

Chemical reactions are very complex processes which include the collision of molecules. During the chemical reactions, bonds between the breakdown of the atom and transformed in new ways. The chemical compounds that react together during the chemical reactions are called reactants, shown on the left side of the equation. They are broken down during the reaction and used as the reaction progresses. The chemical compounds that are formed from the rearrangement and breakdown of the reactants are called products. The products are shown on the right side of the chemical equation. As compare to the reactants, the products are more stable molecules. For example, in the reaction between H2SO4 and Zn, these two chemicals are the reactants, while ZnSO4 and H2 are the chemical reaction products.

                                                Zn + H2SO4       ZnSO4 + H2

                                                 (Reactants)            (Products)

The matter is a material that everything is made of matter. A property that matter has is known as energy. The same quantity of matter can have a diverse quantity of energy. Both energy and matter are identical. For example, if we add some energy into an ice cube, it will turn into liquid. After that, if we add more energy, liquid will turns into steam.

What is the correct "height" or "size" for a piece of oils rigs to become a candidate for "rigs to reef." Remember, oil rigs can be cut into different sizes or parts.

Answers

Answer and Explanation:

An oil rig is a type of piston ring which is situated in the ring grooves. The oil ring is commonly used on small engines to wipe excess oil from the wall of the cylinder during the piston's movement. Through the opening of rings, excess oil returned to the oil reservoir. These rings are not used on the two-stroke cycle engines. These rings are one-piece or two-piece. An oil ring seals the combustion chamber through inherent pressure and controlling the consumption of oil. The inherent pressure of the oil ring is very high on the piston. These rings use an expander, high-pressure unit and inherent pressure. The oil rings are also used to spread the oil around the liner surface.  These rings can be cut into various sizes. An oil ring has an axial.

1. Robin carries the trash from the house to the garbage can outside. Which statement best describes the science of what he did?

He would use less energy if he were to move the garbage faster

He used energy to carry the garbage.

He did not have to work because garbage is light.

He caused the garbage to have potential energy when it moved.

Answers

Answer:

He used energy to carry the garbage.

Explanation:

Energy is the ability to do work. When work is done, energy is expended during the process. Work is done if the force applied on an object moves that object through a distance.

In the case where Robin carries the trash from the house to the garbage can outside, work is done because, the force applied by Robin on the trash effectively helps to move the trash from inside the house to the garbage can outside the house. During the process of moving the trash, Robin expends or uses energy to do the work.

From the given options:

He would use less energy if he were to move the garbage faster is wrong because an increase in speed results in an increase in energy

He used energy to carry the garbage is correct because energy is the ability to do work

He did not have to work because garbage is light is wrong because as long as an object is moved a distance, work is done irrespective of the mass of the object.

He caused the garbage to have potential energy when it moved can only be true if he had raised the garbage from the floor to a height above the ground. However, he only moved it fro inside to outside the house.

Sickle cell anemia and albinism are both recessive traits in humans. Imagine that a couple, already pregnant with fraternal twins, has just learned that they (the couple) are both heterozygous for both of these traits. As the couple's genetic counselor, the couple asks you what is the probability of having both of the twins be albino and have sickle-cell anemia.

Answers

Answer:

81/256

Explanation:

By doing a test cross of albinism and sickle cell anemia you'll see that the probability that one child is unaffected by either conditions will be 9/16. Both children would be 9/16 * 9/16.  

Since fraternal twins are developed from two separate fertilization events the probability chance will be independent.

A disease infects an organism, causing the organism's cells to have less chloroplasts. How will the organism be impacted by having less chloroplasts?
The organism will have less chlorophy reducing its ability to collect energy
The organism will have less cellulose, reducing its ability to remove waste
The organism will absorb less oxygen, reducing its ability to produce sugar
The organism will absorb less water, reducing its ability to create DNA

Answers

Answer:

the organism will have less chlorophyll

Explanation:

chloroplasts contain chlorophyll

Chlorophyll is a green pigment, without it a plant is discolored meaning it lacks of chlorophyll. Less photosynthesis would occur, and less glucose is made as a result. There is less energy released for growth as glucose is needed for respiration.

The color of a light wave is determined by its wavelength. On the COLOR tab, slowly drag the Light wavelength slider back and forth and observe the effect on oxygen production. How does the color of light affect the rate of photosynthesis

Answers

Answer:

The color of light determines how effective chlorophyll pigment will be at absorbing light.

Explanation:

Photosynthesis is a metabolic process that requires light, which is an electromagnetic radiation. Light on the electromagnetic spectrum is determined by wavelength. Each region/color of light occurs at a specific wavelength.

Hence, chlorophyll pigment, which is the major photosynthetic pigment effectively absorbs blue and red light in the visible light region of the electromagnetic spectrum. Hence, the rate of photosynthesis will be affected negatively if the color of light is not the one stated above.
