In three to five sentences, construct an argument that shows why lichens are necessary to establish a new ecosystem after an extreme disturbance.
I would really appreciate it if someone o two people would help me out on this one
Answers
Answer: Lichens affect every species in the ecosystem, in 2013 Russia had a dramatic lichen die off which caused 61,000, 20% of the entire reindeer population to die from starvation. And with fewer deers, the bears and wolves also suffered from the loss of lichens and if it takes a long time for lichens to grow back in an ecosystem, animal declines may take years if ever to be corrected. Lichens serve as a basis for several food chains, especially in artic communities.
The argument which shows why lichens are necessary to establish a new ecosystem is as follows;
Lichens are known to enable algae to live all over the world in many different climates.
On this note, lichens also provide a means to convert carbon dioxide in the atmosphere through photosynthesis into oxygen, a process required by all to survive.
Additionally, lichens provide us with valuable information about the environment around us.
On this basis, lichens are important for establishing a new ecosystem after an extreme disturbance.

What form of energy is responsible for producing changes that occur in Earth’s hydrosphere?
Answers
Answer:
the sun because energy from the Sun heats the Earth unevenly. As a result, convection currents develop in the atmosphere and ocean. These redistribute heat in the atmosphere and oceans.
Answer: Hydropower is created when rapidly flowing water turns turbines inside a dam, generating electricity. Nuclear energy is produced at power plants by the process of nuclear fission. The energy created during nuclear reactions is harnessed to produce electricity.

Explain the 5 ways to reach Hardy-Weinberg equilibrium, does this mean evolution is occurring?
Answers
There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection. If the assumptions are not met for a gene, the population may evolve for that gene (the gene's allele frequencies may change).

the FUNCTION of enzymes. YOU MUST USE
THE WORDS CATALYST, ACTIVATION
ENERGY, RECYCLABLE
Answers
The reaction represented by this graph is a combustion reaction involving the reactants glucose (C6H12O6) and oxygen (O2). The products of the reaction are carbon dioxide (CO2) and water (H2O). Energy is also released during the reaction. The enzyme speeds up the reaction by lowering the activation energy needed for the reaction to start. Compare the activation energy with and without the enzyme
Answer:
Enzymes help speed up chemical reactions in the human body. They bind to molecules and alter them in specific ways. They are essential for respiration, digesting food, muscle and nerve function, among thousands of other roles.
What is the function of an enzyme? They allow chemical reactions to occur at normal body temperature fast enough to sustain life. They reduce the activation energy needed to start a chemical reaction.
There are four steps in the process of an enzyme working. (1) An enzyme and a SUBSTRATE are in the same area. The substrate is the biological molecule that the enzyme will work on. (2) The enzyme grabs onto the substrate with a special area called the ACTIVE SITE.

Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life. The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.

A cell is placed in a hypertonic solution. Which will most likely occur as homeostasis is maintained in the cell?
A.
The cell will gain ATP molecules.
B.
The cell will gain water.
C.
The cell will lose water.
D.
The cell will lose sodium ions.
Answers
Answer:
B the cell will lose water
Explanation:
Because of the hypertonic solution water will move on the concentration gradient leaving the cell and entering the solution. Thus the cell looses water.
When a cell is placed in a hypertonic solution, it will most likely lose water (Option C) as homeostasis is maintained in the cell.
What is homeostasis?Homeostasis is the ability of an organism or a system to maintain a relatively stable internal environment, despite changes in external conditions. It is a key aspect of biology that helps living organisms survive in their environment. Homeostasis is maintained through a series of physiological processes that regulate different aspects of an organism's biology, such as temperature, fluid balance, and pH
A hypertonic solution is one that has a higher concentration of solutes (e.g. salts) outside the cell compared to inside the cell. This creates an osmotic pressure gradient, which draws water out of the cell and into the solution in an attempt to balance the concentration of solutes on both sides of the cell membrane. As a result, the cell will shrink and lose water.

The farmer realizes he could sell mini-dragons as pets, but doesn't want them to breathe fire, because that would be dangerous. Suggest two parental genotypes for parents that would produce mini, non-fire breathing dragons.
Answers
Answer:
ddff and DDFf
Explanation:
From the information given:
Let DD represents the dwarf traits and FF represents the ability for the dragons to breathe fire.
Also, if dd represents the normal traits and ff represents the inability of the dragons to breathe fire.
Then; we can cross a dominant trait for dwarfism which has a heterozygous trait for fire with a recessive trait of normal and nonfire.
The two parental gametes are: ddff and DDFf
Using a Punnet Square:
DF Df
df DdFf Ddff
df DdFf Ddff
From above; we could observe that the proportion of progenitors that will be dwarf and at the same time unable to breathe fire is 50%.
