Which of the following environmental factors would positively influence the survival and reproduction of only light peppered moths?



A.
A forest fire that burns down the trees.

B.
Laws that improve air quality and restrict pollution.

C.
Increasing the number of factories that burn coal into the air.

D.
A disease that infects the light peppered moths and not the dark.

Answers

Answer 1

Answer:

The correct answer is - option B. laws that improve air quality and restrict pollution.

Explanation:

The dark peppered moths were the adaption of the light peppered moths due to the change in the environmental condition of increased pollution that made tree bark dark in color and allows birds to easily prey on the light peppered moths.

This leads to natural selection and light moths become dark but the after Clean Air Act was that there was less pollution then there is less soot in the air, so trees were less black which result in the Light-colored moths would increase, and dark-colored moths would decrease.

If a student tested the bubbles collected in the test tube what would they find they are made of and how do you know?

Answers

Hello. This question is incomplete. The full question is:

A student prepared two beakers with identical sprigs of a water plant as shown below. She placed Beaker A in the shade and the Beaker B beside a fluorescent lamp. She then systematically changed the distance from the beaker to the lamp. She counted the bubbles given off by the plants in each beaker.  

If the student later tested the bubbles collected in the test tube, What would she find they are made of?

Answer:

oxygen

Explanation:

The bubbles are oxygen and we can say that because this is the gas that plants release through photosynthesis. In this case, we can also confirm that the plant that was exposed to fluorescent light, showed more bubbles than the other plant, since the light allowed the photosynthetic rate of this plant to be higher, releasing more oxygen to the environment.

No it’s the way the earth is rotating

Answer:

D. Enzymes change the ideal pH for a reaction to proceed.
E. Enzymes provide a site where reactants can be brought together.

Answers

Stage One: Autolysis

The first stage of human decomposition is called autolysis, or self-digestion, and begins immediately after death. As soon as blood circulation and respiration stop, the body has no way of getting oxygen or removing wastes. Excess carbon dioxide causes an acidic environment, causing membranes in cells to rupture. The membranes release enzymes that begin eating the cells from the inside out.

Rigor mortis causes muscle stiffening. Small blisters filled with nutrient-rich fluid begin appearing on internal organs and the skin’s surface. The body will appear to have a sheen due to ruptured blisters, and the skin’s top layer will begin to loosen.

Stage Two: Bloat

Leaked enzymes from the first stage begin producing many gases. The sulfur-containing compounds that the bacteria release also cause skin discoloration. Due to the gases, the human body can double in size. In addition, insect activity can be present.

The microorganisms and bacteria produce extremely unpleasant odors called putrefaction. These odors often alert others that a person has died, and can linger long after a body has been removed.

Stage Three: Active Decay

Fluids released through orifices indicate the beginning of active decay. Organs, muscles, and skin become liquefied. When all of the body’s soft tissue decomposes, hair, bones, cartilage, and other byproducts of decay remain. The cadaver loses the most mass during this stage.

Stage Four: Skeletonization

Because the skeleton has a decomposition rate based on the loss of organic (collagen) and inorganic components, there is no set timeframe when skeletonization occurs.

Answers

Some fungi and insects benefit each other; the fungi protect the insects from predators and the insects spread spores for the fungi. This is an example of a mutualistic relationship.

What is a Mutualistic relationship?

A mutualistic relationship may be defined as a +,+ type of interaction in which both species benefit from the existence of each other. Example includes lichens, mycorrhizae association, coral reefs, etc.

In the question, the Fungi protect the insects from predators and benefit the insects to get survivability, while in return insects spread spores for the fungi and assist them in their reproduction process.

Therefore, both insects and fungi undergo a mutualistic type of relationship through which both species benefit from the existence of each other.

What type of evolutionary mechanism did this story show?

Answers

Allele frequencies in a population may change due to four fundamental forces of evolution: Natural Selection, Genetic Drift, Mutations and Gene Flow. Mutations are the ultimate source of new alleles in a gene pool. Two of the most relevant mechanisms of evolutionary change are: Natural Selection and Genetic Drift.

This story showed an example of convergent evolution. Convergent evolution is the process whereby organisms that are not closely related independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.

What is in the story ?

In this story, the two species of birds, the crows and the jays, evolved to look similar as a result of living in the same environment and competing for the same resources.

The two species evolved to look similar in order to blend in with their environment, making it difficult for predators to distinguish them from one another. This allowed them to survive and thrive in the same environment.

Therefore, This example of convergent evolution is a perfect example of how species can evolve to look similar in order to survive in the same environment. It also shows how competition for resources can drive species to evolve similar traits in order to survive.

Can two different species of fungi from two different genus' mutate into a new species? i just want to know if it's a possibility, and how gigantic or slim the chances are of it happening.

Answers

Answer:

Yes, it is possible.

Explanation:

In this case, I'm guessing you mean breeding.

If that's the case, they will form hybrids.

Between two different species, inter specific hybrids will be formed.

Between two different genus, intergeneric hybrids will be formed.

There's even rare cases of breeding between two families.

So while it is possible for different species and/or genus to breed and form new species, in interspecific breeding for instance, they will have features similar to the parents but turn out sterile.

So to answer your question, it is possible.
