How does energy affect competition in a rainforest?
Answers
Answer:
Energy affects competition in the tropical rainforest due to the dense population of trees found in this region.
Trees are producers and they compete mainly for water, sunlight and nutrients. Sunlight provides the source of solar energy which is instrumental in its photosynthetic process.
The trees form canopies and create competition among the ones who have lower stems and branches while the ones with longer stems continue to grow taller due to the availability of sunlight.
Competition may also affect the organisms living in this region as they compete for food.

Fossil fuels are preserved remains of animals and plants. They record documents of diversity of life forms. Paleontologists are people who study about fossils.
What are fossils?Fossils are decomposed plants and animals. They can be the preserved remains or traces of living things. Thus the first statement is correct. The second statement that they record documents the diversity of life forms is correct since, by studying fossils we can find which types of living things were there in an area.
The people who study on fossils are called Paleontologists. The fossil formed when an animal walked in mud long ago and then the mud hardened into rock is an example of trace fossils. Most fossil are found in sedimentary rocks.
Fossils tell about both land and water plants and animals. A paleontologist finds a fossil of a fish on a mountain. She can infer that the area was once underwater. Not every but most dead animals and plants form fossils.
No condition can change chemical molecules of a fossils into that in living cells. The oldest rocks contains both complex and simple organisms. Thus the statement is true.

Beavers, large members of the rodent family in North America, are often referred to as “ecosystem/keystone engineers” by wildlife managers. Ecosystem engineers are described as animals that create, alter, or destroy a habitat. Beavers contribute to river ecosystems by bringing down old and dead trees along riverbanks. They use these trees to make their dams. Although these dams are primarily used for protection and food storage, scientists report that these dams change the surrounding environment in different ways.
Given this information, in three to five sentences, describe a potential benefit that beavers contribute to the ecosystem as keystone engineers and describe a plausible impact that the removal of beavers could have on the surrounding ecosystem.
Answers
Answer:The potential benefit that beavers contribute to the ecosystem include sources of food and habitat for some animals.This consists of all the organisms and the physical environment with which they interact.The removal of the beavers will allow for more oxygen to be present within the ecosystem as a result of increased plant population.

The picture shows a Single-celled organism that has a nucleus and organelles, lacks a cell wall, and obtains food by eating other organisms. The organism also has cilia that it uses to move through water. Which kingdom should this organism be classified?
Science
Answers
Protista
Protists are single-celled and usually move by cilia, flagella, or by amoeboid mechanisms. There is usually no cell wall, although some forms may have a cell wall. They have organelles including a nucleus and may have chloroplasts, so some will be green and others won't be. They are small, although many are big enough to be recognized in a dissecting microscope or even with a magnifying glass. Nutrients are acquired by photosynthesis, ingestion of other organisms, or both.

All organisms depend on stem cells for their survival. As an outcome, stem cells may be a requirement for the evolution of specific characteristics in organisms that include regeneration, multicellularity and coloniality.
What is stem cell theory?The stem cell theory of ageing proposes that the ageing process is the result of the inability of different types of stem cells to continue to replenish the tissues of an organism with functional differentiated cells capable of maintaining that tissue's original function.
Thus, stem cells may be a prerequisite for the evolution of specific characteristics in organisms that include regeneration, multicellularity and coloniality.

Find the hot spot on the map. This represents one of the volcanoes of Hawaii, which gets its fuel because the island sits over a hot spot. Hot spots occurs at abnormally hot centers known as mantle plumes. Scientific models depict these plumes of molten rock almost like a lava lamp, with a rising bulbous head fed by a long, narrow tail that originates in the mantle. This type of volcanism, hot spot volcanism, is unique. Why?

Answers
Answer:
1. There's air pollution, water pollution, noise pollution, and light pollution. The worst pollution is air pollution because it can cause severe health problems like respiratory diseases or even cancer.
2. Fossil fuels are resources that are formed from the remains of dead plants and animals. An example would be coal, oil, and natural gas. These fuels are used to generate electricity, power vehicles, heat homes and buildings. Yes, there many other energy sources that can replace fossil fuels.
3. One way to prevent factories from dumping waste water in rivers and oceans is to implement stricter regulations and penalties for those who violate them.
4. One of the best ways to reduce the amount of garbage is to reduce, reuse, and recycle.
5. Yes, I drink bottled water because it's more water to drink from a bottle and its effect on the environment is recycling and being reused.
1. Pollution can be of many types such as air pollution, water pollution, noise pollution, and land pollution. In my opinion, air pollution is the worst because it affects people's health and can cause breathing problems, heart diseases, and even cancer. Discussing this issue in a group can help us understand different perspectives and find solutions to reduce pollution.
2. Fossil fuels are non-renewable sources of energy that are formed from the remains of dead plants and animals. Examples of fossil fuels include coal, oil, and natural gas. They are used to generate electricity, fuel vehicles, and heat homes. However, they are a major contributor to air pollution and climate change. Fossil fuels can be replaced by renewable sources of energy such as solar, wind, and hydro power.
3. Factories dumping waste water in rivers and oceans can have a negative impact on aquatic life and the environment. To prevent this, factories can treat their waste water before discharging it into the environment. Governments can also enforce strict regulations and penalties for factories that violate environmental laws.
4. To reduce the amount of garbage, we can follow the three R's - reduce, reuse, and recycle. We can reduce the amount of waste we generate by using reusable bags, bottles, and containers. We can also compost organic waste such as food scraps and yard waste. Recycling can also help reduce the amount of garbage by turning waste into new products.
5. I try to avoid drinking bottled water because it generates a lot of plastic waste that can take hundreds of years to decompose. Plastic waste can also harm wildlife and pollute the oceans. Instead, I use a refillable water bottle and fill it with tap water. Tap water is safe to drink in most developed countries and can be a more sustainable choice.

A damaged heart can't pump blood as effectively from your lungs out to your body. Blood backs up, raising pressure in the veins inside your lungs. This pushes fluid into your air sacs. As liquid builds up, it gets harder to breathe.

What type of response occurs when you watch someone eating a lemon and your face puckers?
external response
sour response
internal response
lemon response
Answers
Answer:
The type of response that occurs when you watch someone eating a lemon and your face puckers is an external response. An external response is a physical reaction that is visible to others and occurs in response to a stimulus, in this case, the sight of someone eating a lemon. It is also sometimes called a behavioral response.
An internal response, on the other hand, is a response that occurs inside the body and is not visible to others. For example, when you eat a lemon, you may experience an internal response such as an increased production of saliva in your mouth or a sour taste in your mouth.
A sour response is a type of internal response that refers specifically to the taste of something that is sour, such as a lemon.
A lemon response is not a commonly used term in psychology or physiology. It could refer to any type of response that is related to lemons, such as the external response of puckering your face or the internal response of experiencing a sour taste.
