Answer:
16grass/m²
Explanation:
Given parameters:
Number of grasses in quadrat = 4
Area of the square = 0.25m²
Unknown:
Population density = ?
Solution:
Population density is the number of organisms per given area;
Population density = [tex]\frac{number of grasses}{area of quadrat}[/tex]
Population density = [tex]\frac{4}{0.25}[/tex] = 16grass/m²

1. Identify one environmental factor that could cause a base sequence in DNA to be changed to a different base sequence.
2. Explain why, in a mammal, a mutation in a gamete may contribute to change in the population of the organism while a mutation a body cell will not.
Answer:
Explanation:
1 Long term exposure to harmful genotoxic chemicals or ionizing radiation can cause changes in the base sequence of DNA.Chemicals might induce DNA mutations, such as polycyclic hydrocarbons (fumes found in oil stations, or smoke from a tobacco cigarette), intercalating agents such as Ethidium Bromide (carcinogen), but also radiations such as UV-radiation (C and T bases are most vulnerable and would bind to identical bases unstead of their
2 Genetic changes that are described as de novo (new) mutations can be either hereditary or somatic. In some cases, the mutation occurs in a person’s egg or sperm cell but is not present in any of the person’s other cells. In other cases, the mutation occurs in the fertilized egg shortly after the egg and sperm cells unite. (It is often impossible to tell exactly when a de novo mutation happened.) As the fertilized egg divides, each resulting cell in the growing embryo will have the mutation. De novo mutations may explain genetic disorders in which an affected child has a mutation in every cell in the body but the parents do not, and there is no family history of the disorder.
Somatic mutations that happen in a single cell early in embryonic development can lead to a situation called mosaicism. These genetic changes are not present in a parent’s egg or sperm cells, or in the fertilized egg, but happen a bit later when the embryo includes several cells. As all the cells divide during growth and development, cells that arise from the cell with the altered gene will have the mutation, while other cells will not. Depending on the mutation and how many cells are affected, mosaicism may or may not cause health problems.

A student conducted a comparative investigation to test the hypothesis that different areas of New York City have different levels of air pollution. Which is a likely benefit of this comparative investigation?
A It provides her with a large amount of information about air pollution in New York City.
B It provides her with results that are valid for a long time.
C It requires that she observe a limited number of variables.
D It allows her to learn about the causes and effects of air pollution in major cities.
Answer: A. It provides her with a large amount of information about air pollution in New York City.
Explanation:
A comparative investigation is when data is collected in order to make a particular comparison.
With regards to the question, the student conducted a comparative investigation in order to test the hypothesis that different areas of New York City have different levels of air pollution.
The benefit of this study done by the students is that it will provide her with a large amount of information about air pollution in New York City. The area with the highest air pollution, what causes air pollution and other necessary information can be gotten.
Therefore, the option is A.

Which soil-based compounds do plants use to create amino acids from glucose?
Answer:
Explanation:
When combined with nitrates from the soil, glucose will form amino acids. When amino acids join together, they form proteins. So, think of glucose as an important source of carbohydrates and, in the right combination, as part of a protein. Without glucose, plants won't grow or reproduce.
NITRATES are the soil-based compounds that plants use to create amino acids from glucose.
WHY DO PLANTS NEED AMINO ACIDS?
Plants require amino acids in order to synthesize proteins, which serves as the hormones and enzymes that carry out metabolic activities.WHAT ARE NITRATES?
Nitrates are nitrogenous compounds (NO3) found in the soil. Nitrogen in the atmosphere (N2) is fixed by certain bacteria called NITRIFYING BACTERIA. This nitrogen fixation process makes nitrogen available in the soil in form of nitrates, which is the only usable form for plants.Plants synthesize amino acids, which are precursors of proteins, by combining the glucose made from photosynthesis with the nitrates absorbed from the soil.
Therefore, the soil-based compounds that plants use to create amino acids from glucose is NITRATE.

PLEASE HELP!!!? Are humans an invasive species? Why or why not. GIVE TWO PIECES OF EVIDENCE TO SUPPORT YOUR OPINION.
Answer:
I think yes, humans are an invasive species.
Explantation:
I think humans are an invasive species because they are everywhere, and very few places in the world do not have humans. Humans are in control of the planet because of their number. Humans are not going to be extinct ever. They are always going to be here on earth. If somebody finds new land, they make a base/camp and send other people to live there and to populate it. Like in North america, settlers came and sent men to live there. They hunted animals and set up homes. Then, more and more people came and soon all that is left is a over populated land with citys and cars and humans everywhere.

The mechanism by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as Photosynthesis.
What steps are involved in a plant's photosynthesis?Green plants and various other organisms convert light into chemical energy through a process called photosynthesis. Light energy is gathered and utilised during photosynthesis in green plants to change waters, carbon dioxide, and minerals into oxygen- and energy-rich organic molecules.
What makes photosynthesis so crucial?The significance of photosynthesis Solar or radiant energy is converted into chemical energy during photosynthesis. The production of agricultural crops is directly impacted by the rate of photosynthesis. All living things require oxygen, which it provides for the atmosphere. It keeps the ecosystem's carbon dioxide and oxygen levels in check.

If the pituitary is so important and Eric is not getting replacements of hormones the pituitary makes (except for ADH), why isn’t he dead? To answer this question, think through the cascade of events from hypothalamus to effect.
Answer:
The absence of ADH is not too dangerous.
Explanation:
If there is no place for the storage of ADH hormone in the pituitary hormones, no death occur of the individual because ADH is related to the conserve of fluid in the blood. If this hormone fails to perform its function properly, it causes the body to retain too much water. This more water retention may cause you to feel heavier than normal, and less active so the person did not die due to the deficiency of this disease.
