Answer:

An ecosystem only has a certain amount of resources to support a certain number of organisms.

Explanation:

An ecosystem consist of resources and organisms. Resources are the material which are responsible for the survival of living organisms in that ecosystem. Examples of resources are light, water, oxygen and food substance. In the absence of these resources, organisms will die.

UkoKoshka [18]

The correct answer should be loss.
When your skin is cut open, obviously a little blood will run out as a result of that. This case is no different - the person who fell and has an abrasion on the knee will experience a slight loss of blood through that tiny wound which is the result of them falling on the ground.

Explain how the boiling of water and the cooling of water vapor is a reversible reaction. With hydrogen bonds between water mol

My name is Ann [436]

Answer:

When water is boiled water molecules changed into vapors when these vapors condensed water changed into liquid.

So it is reversible reaction.

Explanation:

Water molecules are connected through the hydrogen bonding. When water is boiled the kinetic energy of water molecules increased and point is reached when kinetic energy is so high and water molecules overcome the external pressure and escape from the surface. Thus water molecules convert into vapors.

In case of cooling process extra energy is released. Vapors becomes cooled and kinetic energy decreased vapors are changed into liquid state.

When water is boiled water molecules changed into vapors when these vapors condensed water changed into liquid.

So it is reversible reaction.

If the activation energy required for a chemical reaction were reduced, what would happen to the rate of the reaction?

Ratling [72]

The rate would increase because more molecules would collide at the activation energy, which will cause more molecules to react, and thus it will speed up the reaction rate.

Maru [420]

Answer:

start codon - AUG

in-sequence amino acid - AAA, UGC, AUC, CAC, GCA, ACU

stop codon - UAA, UAG, UGA

Explanation:

From the amino acid chart, the start codon is represented by the codon AUG which also code for the amino acid methionine. There are three stop codons including UAA, UAG, and UGA. The stop codons signal the end of the translation process of the mRNA. Every other codon within the mRNA chain codes for different amino acids except methionine.

Hence, using the attached amino acid chart:

start codon - AUG

in-sequence amino acid - AAA, UGC, AUC, CAC, GCA, ACU

stop codon - UAA, UAG, UGA
