Answer:

The community will slowly decline, or be just fine, or be better off.

Explanation:

Wolves being killed in Yellowstone showed that Yellowstone suffered, because there was nothing to kill the elk, so their population exploded and they ate everything.

If certain rats were gone in certain areas, then the community/environment would be fine, because rats eat birds and other small animals (they eat too many of them).

And if stray cats were gone then certain forests would be better off and see an increase in birds population, stray cats eat birds.

Answer:

formed by a volcano

Explanation:

Rocks are formed on Earth as igneous, sedimentary, or metamorphic rocks. Igneous rocks form when rocks are heated to the melting point which forms magma . Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock.

The Hawaiian Islands are nearly entirely made of basalt lava, the most abundant type of rock on the planet.

Hot, molten rock crystallizes and hardens to produce igneous rocks, which are named after the Latin word for fire. The melt begins deep inside the Earth around hot regions or active plate borders, then it rises toward the surface. Depending on where the molten rock hardens, igneous rocks are classified as either intrusive or extrusive.

Thus, Hawaiian islands are made up of basalt ; the most common rock on the earth.

Explanation:

Answer:

The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH2 to molecular oxygen. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water.

Explanation:

The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.8

Explanation:

Out of the given options 3 that is "it pumps blood to the organs" is not a function of the respiratory systems.

The respiratory system is a network of organs and tissues that assist you in breathing. This system assists your body in absorbing oxygen from the air so that your organs can function.

It also removes waste gases from your blood, such as carbon dioxide. Allergies, illnesses, and infections are common difficulties.

The respiratory system contributes to the warming and humidification of the air we breathe. The air is warmed as it goes through the nasal passages and pharynx, which helps to protect the lungs' sensitive tissues.

The respiratory system contributes to the production of sound. When air flows through the larynx (voice box), the vocal cords vibrate, producing sound.

Thus, the option 3 is not the function of the respiratory system.

Explanation:

How a Forest Ecosystem Matures . Forest ecosystems tend to always be moving toward maturity or into what foresters call a climax forest. This maturing, also called forest succession, of the ecosystem increases diversity up to the point of old age where the system slowly collapses. One forestry example of this is the growth of trees and the entire system moving toward an old growth forest.

A Large amount of warbler species, crossing over between homologous chromosomes, is closely involved in genetic variation. The stage that most contributes to diversity is stage C, where you can see chromosomes after crossing-over.

There are different mechanisms involved in producing genetic variation among descendants, are-

The Crossing-over events occur between two homologous chromosomes within the equatorial plane and make the daughter cells genetically different from the first one.

The Chiasma is the position where two homologous chromatids interchange genetic information, giving an area for brand spanking new genetic material or information to be provided to descendants.

After crossover, homologous chromosomes get separated again. In the attached image there are four different stages of meiosis.

Stage C is the one that contributes foremost to diversity. We can see that crossover has already occurred between homologous chromosomes and that they have already interchanged segments.

In the image, you will see the difference between chromosomes that have gone through the crossing over mechanism, and chromosomes that have not. The difference in color represents segments interchange and variation.

Therefore, that answer shows the contribution to diversity among the warblers.

Answer:

Explanation:

stem cells are manipulated to specialize into specific types of cells, such as heart muscle cells, blood cells or nerve cells. The specialized cells can then be implanted into a person. For example, if the person has heart disease, the cells could be injected into the heart muscle.

Daughter cells are created when stem cells divide properly in the body or a lab to create more cells. These daughter cells either develop into fresh stem cells or into differentiated cells with a more specific role, such as bone, blood, brain, or heart muscle cells.

According to research, cardiomyocytes made from pluripotent stem cells can develop into beating human heart muscle cells that both produce the required signals and restore muscle lost during a heart attack.

Stem cells have the ability to multiply and develop into a variety of relatively mature cells. When inserted into a blastocyst, embryonic stem cells have the ability to develop into any organ in the human body.

Therefore, theoretically, every organ in the body might be replaced using embryonic stem cells.

Explanation:

Alana's error regarding the energy of the ball is that kinetic energy is not made; it is a result of energy transformation. The second option is true regarding the energy conversion.

The law of conservation of energy says that energy is neither created nor destroyed but only converted from one form to another, such as from the kinetic to the potential and vice versa. Here, the ball is placed at the top, where it has no motion, but the ball has potential energy, and that potential energy gets converted into kinetic energy when the ball starts to roll down the hill. After sometime, the ball spontaneously stopped on the ground, and the kinetic energy was converted into potential energy.

Hence, Alana's error regarding the energy of the ball is that kinetic energy is not made; it is a result of energy transformation. The second option is true regarding the energy conversion.

Answer:

Because limiting factors affect plant growth

Explanation:

A limiting factor is a condition that limits the population's growth in an ecosystem by slowing or stopping its growth. These factors are generated by the lack or excess of a particular resource. In plants, limiting factors include, among others, light, water, temperature, oxygen, food, (i.e., nutrients and minerals), space, etc. In this case, the farmer must know which greenhouse conditions are limiting factors in order to ensure the survival and optimal development of the plant population.
