1. Why is diffusion important for living organisms?
2. Define concentration gradient.
3. What is the effect of concentration gradient on the rate of diffusion?
4. What is the effect of surface area on the rate of diffusion?
Answer:
1. because it allows them to gain the useful substances they require to obtain energy and grow, and lets them get rid of waste products.
2.The difference in the concentration of a substance between two areas is called the concentration gradient . The bigger the difference, the steeper the concentration gradient and the faster the molecules of a substance will diffuse. The direction of diffusion is said to be 'down' or 'with' the concentration gradient.
3.The greater the difference in concentration, the quicker the rate of diffusion. The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly. The greater the surface area, the faster the rate of diffusion.
4.The greater the surface area, the faster the rate of diffusion.

Describe the role of competition in the simulation?
Answer: Competition ensures the survival of the fittest.
Explanation: The better characteristics and genes can be passed on.
Answer:
Competition can sometimes be viewed as not always necessary in an organisation especially when it comes to training; however I oppose this idea, especially in the context of business simulation games. There are various advantages of creating healthy competition within a business simulation game environment, just like in the real business world:

What is the difference between a mass extinction and a regular (background) extinction? (1 point)
O Mass extinction can be caused by ecological factors like climate change and loss of habitat.
O Mass extinction is ongoing and is a regular process that results from evolution
O Mass extinction occurs over a long period of time.
o Mass extinction involves many species over a short period of geologic time.
Mass extinction happens when many individuals of a species are lost within a short period while regular extinction happens over a longer period of time.
Mass extinction versus regular extinctionMass extinction refers to the loss of many species within a short period of time.
Mass extinction can be caused by catastrophic events that result in the destruction of habitats, climate change, extreme temperature change, volcanic eruptions, and so on.
If the loss of species happens over a long period of time, it is no longer considered mass extinction but regular extinction.

Four of the following are important ecological services provided by forests; one is not. Choose the one that is not. Group of answer choices Provides wildlife habitat Stores atmospheric carbon Soil erosion is reduced Recreation Influences local and regional climate
Forests act as habitats for wildlife, acts as carbon sinks, help reduce soil erosion, and influence local and regional climate.
Forest's ecological servicesThese are services that forests provide for the biotic component of the ecosystem.
Forests serve a wide variety of services to humans and animals. They act as sinks for carbon, provide habitats for wildlife, provide foods for humans and animals, protect watersheds and soils, among several other services.
Forests are also able to influence local and regional climate due to their ability to serve as sinks for carbon dioxide, a greenhouse gas capable of causing warming.
Forests, however, may not serve recreational purposes, except they are specifically modified to do such.

6. List What types of
particles make up a
carbon atom?
Answer:
The subatomic particles in the nucleus of a carbon atom are protons and neutrons.
Explanation:
The atomic nucleus contains protons and usually neutrons (except for hydrogen-1 (protium) atoms. The number of protons is an element's atomic number and is the same for all atoms of an element. Carbon has atomic number 6. So all atoms of carbon have 6 protons in their atomic nuclei. Carbon atoms also contain neutrons in their atomic nuclei, which may number 6, 7, or 8.

Answer:
1. Many fronts cause weather events such as rain, thunderstorms, gusty winds, and tornadoes. At a cold front, there may be dramatic thunderstorms. At a warm front, there may be low stratus clouds. Usually, the skies clear once the front has passed.
2. As the warm moist air rises, towering clouds often form releasing energy in the form of brief, intense rain storms with high winds and lightning. On the other hand, warm fronts will ride up and over cold air near the surface. As it rises, the air cools and the humidity condenses to form clouds and precipitation.

A human cheek cell's cycle is 24 hours. The stages within the cell cycle vary in length. G1 phase - 11 hours, G2 phase - 4 hours, S phase - 8 hours, M phase - 1 hour. Why does the cell spend 23 hours in interphase (G1-S-G2), while it spends only one hour in the M phase?
a.Interphase consists of the Gap 1 and Gap 2 phases, in which the cell is dormant while the chromosomes align.
b.Interphase is when cells are dormant while they decide whether they want to replicate their chromosomes.
c.Interphase follows mitosis, when daughter cells double their chromosomes, which takes 23 hours.
d.Interphase takes a long time because it is a preparatory stage where the cell makes proteins and organelles and doubles its chromosomes.
Answer:
answer is c
Explanation:
The cell needs a lot of preparation and checks in G1, S and G2 to do mitosis. especially in the G1 phase which is the longest phase. It is explained by the fact that the cell should "rest and recover" after the last mitosis before getting into the second one

An increase in ATP levels would tend to ____________ the PDH complex. Activate inhibit phosphorylate
An increase in ATP levels would tend to inhibit the PDH.
The oxidation of pyruvateAfter the break down of glucose through the metabolic pathway known as glycolysis, the end product, pyruvate, is converted to acetylChoA in the citric acid cycle.
Pyruvate dehydrogenase (PDH) is the first enzyme of the citric acid cycle that is activated by its substrate pyruvate and inhibited by its products acetylChoA together with Adenosine Triphosphate (ATP).
This means that an increase in ATP negatively regulates the enzyme, pyruvate dehydrogenase.
Therefore, an increase in ATP levels would tend to inhibit the PDH.
