Answer:

Form hypothesis: Where do you think trees get the nutrients they need to grow?

I think the trees get the nutrients from the soil and sunlight

Predict: Based on your hypothesis, how will the tree population change if ALL other organisms (deer, bears, and mushrooms) are removed from the forest?

I think they will increase dramatically because there is nothing affecting them badly.

Analyze: Remove ALL organisms except trees. Click Advance year a few times and select the DATA tab. Was your prediction correct? Explain what you found.

Yes my hypothesis was correct without the other organisms affecting the trees growth the tree population increased.

Draw conclusions: Substances that contain carbon and are produced by living things are called organic. Examples of organic materials are sugar, blood, protein, and fat. Other materials, like water, carbon dioxide, oxygen, and ammonia, are called inorganic.Some living things, called producers, can produce the organic materials they need (like food) from inorganic matter. All other organisms are consumers; they consume organic matter since they cannot make it themselves.

Do your results show you that trees are producers or consumers? Explain.

Trees are producers because they make it by using the sun's light.

Analyze: Click the FOREST tab. Click the plus (+) button for mushrooms several times. Click Advance year a few times. Select the DATA tab. How did adding mushrooms affect trees?

adding the mushrooms didn’t affect the trees.

Extend: The mushrooms thrived without hurting trees. How could this happen? Try for two possible explanations. Write your ideas in the space below.

The mushrooms are decomposers; they thrive off of dead things including the trees so they  do not harm the trees at all.

Explanation:

The trees in the forest controls the flow of water on the land.

When heavy rainfall occurs the trees help in trapping the water in the soil which reduces the chances of flood. These trees also provide habitat as well as food for living organisms that lives in the forests.

The trees get the nutrients they need to grow from the soil with the help of their roots. Decomposers present in the soil feed on dead bodies which turn into nitrogenous substances that is used by the trees for making amino acids.

The tree population increases if all other organisms such deer,  bears, and mushrooms are removed from the forest because these organisms feed on the trees so increase occur in the tree population.

What is the purpose of Mitosis? *
A. To produce an egg and a sperm cell.
B. To produce a new organism (like bacteria).
C. To produce a new cell (NOT a new organism).
D. To differentiate.

Answers

Answer:

C.

Explanation: Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.

Hope this helps! Have a nice day!

Answer:

C. to produce a new cell

Explanation:

Mitosis consists in replicating the genetic material of a mother cell in order to make two identical daughter cells; this is a diploid process. In order to make an egg or sperm cell and eventually a new organism, the correct process would be meiosis, since it combines the DNA between two cells and it is an haploid process.

Why is it important for gametes to be haploid cells?

Answers

It is important that the chromosomes are haploid, because when the sperm and the egg fuse together the cell will have 46 chromosomes.

The reason why it is important for gametes to be haploid cells is because: when the sperm and the egg fuse together the living sex cells will have 46 chromosomes.

Gametes are also referred to as sex cells and they can be defined as the reproductive cells in a living organism.

Generally, the male reproductive cell is known as a sperm while the female reproductive cell is known as an egg.

Since gametes are reproductive cells or sex cells, they are typically made up of haploid set of chromosomes.

Basically, it is very important for gametes to be haploid cells so that when the sperm and the egg fuse together, the living sex cells will have a total of 46 chromosomes.

Farmers brought nutria, a type of large rodents, from South America to North America in the 1990s. They wanted to raise the rodents for their fur. Some of these rodents escaped into the wild and became a major pest in the Gulf Coast and Chesapeake Bay regions. Grasses and shrubs in these regions are vital, because they provide food and shelter for many species. They also help in preventing soil erosion. The nutria are eating up all the grasses and shrubs, which affects the food cycles of these regions. The entire ecosystems are being disrupted.

Moreover, nutria pose a direct threat to humans. These rodents are an effective vector for carrying parasites that can cause disease in humans. They also damage property. The burrows created by nutria can damage dams and building foundations as well as cause erosion near streams and lakes.

the answer from pluto/edmentum

Answer:

The apple snail is a native species of Argentina, Bolivia, Brazil, Paraguay, and Uruguay. Southeast Asia legally imported this alien species to use it as a protein source. Later, this species was brought to places like Hawaii as a source of food.

Like most, if not all, invasive species, the apple snail outcompetes native species for resources. This is because it reproduces rapidly (laying hundreds of eggs every few weeks) and lacks predators. As a result, the snails spread rapidly to aquatic biomes and modify the natural balance of aquatic ecosystems.

Lion and cheetah populations compete for the food source of zebras, and lions outcompete cheetah.

Limiting factors are those factors in the ecosystem which can limit the growth of population of a species in an ecosystem. Predation and competition are two limiting factors in the ecosystem that can decrease or extinct the population of a species. Predation is a limiting factor in which predatory organisms are dependent upon a prey organisms. This is natures way of limiting the surplus growth of prey population and to maintain a balance in ecological community. Competition is a limiting factor in which one or more same or different type of organisms compete for the same resource in an ecosystem. The one which is more competitive will derive those resources other than the one which is less competitive.

According to the given data, it is evident that the population decline in predator cheetah and lion populations because of decline in zebra population but the decline in cheetah population is more than that of lion. It explains the fact that lion is more competitive than cheetah in deriving the food which is already limited. Therefore, lion outcompete cheetah.

Southern Florida has many tropical hardwood hammocks—forest habitats that are warm, wet, and populated with many broad-leaved evergreen trees. Why might a plant native to an ecosystem with a cooler climate do well if introduced to a tropical hardwood hammock? Group of answer choices The trees in the tropical hardwood hammock are better at competing for native resources than the introduced species are. The wet conditions in the tropical hardwood hammock disrupt the life cycle and limit reproduction of the introduced species. Freezing temperatures that normally limit the population in the cooler climate are lacking in the tropical hardwood hammock. Pollinators and seed carriers that normally increase the population in the cooler climate are lacking in the tropical hardwood hammock.

Answers

Answer:

Freezing temperatures that normally limit the population in the cooler climate are lacking in the tropical hardwood hammock.

Explanation:

The tropical hardwood hammocks are habitats that act as small ecosystems markedly different from the surrounding environment, and they may be seriously threatened by introduced plant species. In Florida, exotic plants have been introduced into the tropical hardwood hammock habitat, reaching to about 50% of the flora in some areas. The mature hammock of these habitats can generate a shade that maintains a temperature of several degrees cooler compared to their neighboring habitats, and thereby promoting invasion by exotic species.

Answers

Answer:

C. a dog buries a bone in the backyard

Explanation:

A dog burying a bone in the backyard is not an observation in terms of scientific methods.

Observation is the process of acquiring data about a phenomenon under study.

Most times, senses are used in making observations. Our sense of taste, hearing, sight etc. comes handy when making observation.

Also, we can use some specialized equipment to make observations.

A dog burying a bone in the backyard is not an observation. None of the senses nor instruments are used to gather any relevant information.

3. Which of the following is a defining characteristic of a prokaryotic cell?

a. The method of cellular Respiration
b. The composition of the cell membrane
C. Absence of a membrane-bound nucleus
d. The method of movement

Answers

Answer:

C

Explanation:

Prokaryotic cells do not have any membrane-bound organelles, only eukaryotes do.

The prokaryotic cell is a simple primitive cell, unlike the complex eukaryotic cells. The absence of a membrane-bound nucleus is a characteristic of prokaryotes. Thus, option C is correct.

What is a prokaryotic cell?

Prokaryotes have been the cells that have lived on earth for millions of years ago. They are made of single cells and hence are unicellular. Unlike the eukaryotic cell, they have simple mechanisms of living and reproduction.

They lack a centrally located defined nucleus that is not covered in any membrane and lies simply in the cytoplasmic material. Also, they lack organelles that make them different.

The genetic material is located in a concentrated form in a structure called the nucleoid that lacks a nuclear membrane.

Therefore, option C. the prokaryote lacks a membrane-bound nucleus.
