In a new environment colonization of the substrate occurs in sequence hence it is common to see growth in biodiversity of the new ecosystem with time. Ecological succession begins with pioneer plants in primary succession. These pioneer plants break down rocks to soil hence releasing bound nutrients and making them available to higher plants up in the succession line. Therefore, in the beginning, one will find plants such as mos, lichens and annual plants such as grasses. The biodiversity will increase to include shrubs, then plants like trees will eventually appear.

lianna [129]

The group of the options are given below:

Individuals of population X are predators

Individuals of population X are prey

Individuals of population Y caught and spread a disease.

Individuals of population Y lost their shelters after a flood

Answer:

The correct answer would be - Individuals of population X are predators.

Explanation:

The limiting factor is a factor that prevents or slow the growth of the population. In this case the population an increase of a population results in the decrease in the other population directly.

Increase in the population X results directly in the dcrease of the decrease of population Y. Such relation of the two variables in apopulation growth occurs when there is predator- prey relatioship among two organism or population. Increase in the population of predator result in decrese of the population of prey.

Which statements are true for dna and rna? check all that apply?

LekaFEV [45]

Since there are no given choices, I would just compare and contrast DNA and RNA. These are the two types of nucleic acids in the human body. The structural unit of nucleic acids are composed of repeating units of monomers called nucleotides. Nucelotides are composed of three functional groups: sugars which are specifically pentoses (5-Carbon sugars), phosphate group and nitrogenous base.

Now, the RNA and DNA differ in the composition of these sugars and the bases. Based on the nitrogenous bases and sugar, the DNA has a deoxyribose as the sugar and its 4 bases are adenine, guanine, cytosine and thymine. For RNA, the sugar is ribose while its 4 bases are <span>adenine, guanine, cytosine, and uracil.

They also differ in their structure. </span>DNA is a double stranded β-helix with a long chain of nucleotides. RNA is composed of a shorter chain with a single strand α-helix structure.

Lastly, they differ in their functions. T<span>he DNA is responsible for storing the genetic information while the RNA is responsible for transporting the genetic information to the ribosomes which synthesize proteins.</span>
