Answers
The benefits of wildfires in grasslands and northern forests are similar - b. increased food production for grazers
Wildfires affect the ecosystem by
- remove low-growing underbrush,
- clean the forest floor of debris,
- open it up to sunlight,
- nourish the soil.
- The grassland and northern forests ecosystem are maintained by wildfire.
- It warms up the soil and reduces leaf litter.
- It allows sunlight to penetrate and grow more food production for grazers

How are the benefits of wildfires in grasslands and northern forests similar?
a. increased tree quantity
b. increased food production for grazers
c.increased amount of lichensd. all of the above
If you are, the answer would be letter B.
Wildfires not only do they remove dead and decaying plants that act as fuel for future fires — ones that will be more intense and disastrous, wildfires work to eliminate dense foliage and thin out the forest allowing plants closer to the forest floor to come in more contact with sunlight and rain, “enabling a new generation of seedlings to grow”
>>>forest fires play a vital role in maintaining nature’s constant cycle.

An increase in available food and and also decrease in predators would most likely increase the genetic variation in a population.
Explanation;
Genetic variation is essential for natural selection since the natural selection can only increase or decrease the frequency of alleles that already exist in the population. Genetic variation may be caused by mutations, and random mating between organisms.
Increase in the available food also increases the genetic variation as organisms are able to interact freely and thus increases the chances of random mating.
Answer:
an increase in availability of food

The excretory system is responsible for removing all of the following from the body excep t
A. Toxic Waste B. Gaseous Waste C. Dissolved molecules D. Cells
Answer:
D. Cells
Explanation:
The excretory system consists of organs that help the body to get rid of excess and waste materials from the body, and also helps in maintaining internal homeostasis in the body. These organs include the large intestine, skin, lungs, kidneys. Most of the wastes are products of metabolism. These waste materials that are no longer useful to the body could be in liquid or gaseous form. Examples of substances removed from the body by the excretory system are urine, feces, sweat etc.
Cells are not part of the substances removed by the excretory system.

a. viruses are not living since they are smaller than a cell.
b. the cell is the most basic unit of life.
c. all living things are composed of one or more cells.
d. all cells come from other cells
Answers
The correct answer is option a. viruses are not living since they are smaller than a cell.
The cell theory does not propose the explanation for the viruses. As the viruses were discovered by Dmitry Ivanovsky in 1892, after the cell theory was proposed.
After advancement in microscopy, in year 1838 Schleiden and Schwann proposed cell theory.
The cell theory proposed by Schleiden and Schwann suggested that all the living organism are made up of cell. These cells are the smallest unit, which can perform all the function, which is required for a life, they can also divide, hence, it is the functional unit in all forms of life. They also said that a living organism at least have a cell or more than one cell.
Answer:
The correct answer would be an option a.
Cell theory was mainly formulated Matthias Schleiden and Theodor Schwann in 1839.
They postulated that:
All cells arise from pre-existing cells.
Each living organism consists of one or more types of cells.
The cell is a basic functional and structural unit of all living organisms.
Thus, option a. would be the correct answer.
