COMBINATION REACTION:
Combination reaction is a reaction where two or more elements or compounds combine to form a single compound. Such reactions are represented by equations of the following form: X + Y → XY. The combination of two or more elements to form one compound is called combination reaction
An example could be lithium reacting with sulfur to give lithium sulfide. When magnesium burns in air, the atoms of the metal combine with the gas oxygen to produce magnesium oxide.

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
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.

the FUNCTION of enzymes. YOU MUST USE
THE WORDS CATALYST, ACTIVATION
ENERGY, RECYCLABLE
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.

What form of energy is responsible for producing changes that occur in Earth’s hydrosphere?
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.

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.
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%.

Reproduction is not a life process still organisms spend a lot of energy on it. Give reason.
Answer:
Reproduction is not a life process, but still organisms spend a lot of energy on it. ... The reproduction is not necessary to ensure living but it is required to ensure that the continuation of the living organisms and generations of the next cycle of living. It is necessary for ensuring the stability of the population.
Reproduction also helps in increasing the population of the species. All the processes which are necessary to maintain life in an organism are called life processes. Reproduction is not considered a life process because it is not necessary to maintain life.
