Answers

1. the availability of food, water, shelter and space.

2. Common limiting factor resources are environmental conditions that limit the growth, abundance, or distribution of an organism or a population of organisms in an ecosystem. The limiting factor also causes competition between individuals of a species population.

Example: Space, food, or water.

3. Limiting factors, such as food, would sometimes cause one organism to kill another to survive or fight over that factor. But with space, it would get crowded probably.

5. "Native people" are ethnic groups who are the original inhabitants or descendants of the original people.

6. I would say do an experiment or something???

7. A variable is any factor, trait, or condition that can exist in differing amounts or types.

8. The dependent variable is what is being measured in an experiment or evaluated in a mathematical equation. The dependent variable is also called the outcome variable.

9. A typical use of a control group is in an experiment in which the effect of a treatment is unknown and comparisons between the control group and the experimental group are used to measure the effect of the treatment.

Example: when testing for a new pill, one group is given the pill to see affects, one group (the control group) is given a placebo and is used to see what happens when given a placebo.

If a cell is exposed to cyanide most of the cyanide will be found within which part of the cell?

Answers

Answer:Cyanide will be found in mitochondria of cell.It is a toxin for human body and it prevents the body from using oxygen.Our body cells has an organelle called mitochondria which is known as the power house of the cell as it generates energy for the cells to perform their function.Cyanide binds to the enzyme cytochrome c oxidase which is found in mitochondria and inhibits the uptake of oxygen from bloodstream.This is the reason most of the cyanide will be found in mitochondria.








cyanide halts cellular respiration (by inhibiting an enzyme) and as we know one of mitochondria functions is exactly cellular respiration.
so answer is: within mitochondria

8. Unlike weather, climate A. describes the average conditions and atmospheric patterns of a region over time.
B. describes the day-to-day condition of the atmosphere of Earth.
C. involves variations in precipitation.
D. involves variations in temperature.

Answers

Unlike weather, climate describes the average conditions and atmospheric patterns of a region over a period of time. Weather is the day-to-day atmospheric conditions. It includes windy days, sunny, rainy, cloudy and etc. Weather then describes the state of an atmosphere at a place and time to its heat, dryness, sunshine, wind, rain. Climate on the other hand is the prevailing conditions of an area over a period of time, for instance, tropical climate.
It is climate (A) that describes the average conditions and atmospheric patterns of a region upon the Earth, over a period of time. It is distinctive from the weather which describes the specific meteological activity taking place at a specific time and in a specifc location upon the Earth.

Which statement describes a limitation of the kinetic-molecular theory for a gas?a. The theory assumes that particles do not experience intermolecular forces.
b. The theory states that pressure is inversely proportional to volume.
c. The theory assumes that particles are in random and continuous motion.
d. The theory states that pressure increases with temperature.

Answers

I think the correct answer from the choices listed above is option A. A  limitation of the kinetic-molecular theory for a gas is the theory assumes that particles do not experience intermolecular forces.This cannot be completely true since interactions between particles is normal.

Answer:

A
