Answer: Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support simple plants such as grasses. These grasses further modify the soil, which is then colonized by other types of plants. Each successive stage modifies the habitat by altering the amount of shade and the composition of the soil. The final stage of succession is a climax community, which is a very stable stage that can endure for hundreds of years.
Explanation:
The correct answer is c) DNA.
The instructions for making proteins come originally from DNA. DNA is a macromolecule made of polynucleotide. Each nucleotide made of a phosphate, deoxyribose sugar and one of the four nitrogenous bases. The nitrogenous bases are adenine (A), guanine (G), cytosine (C) and thymine (T). The sequence of three bases in the DNA called codon. Each codon of the DNA codes for a particular amino acid for the synthesis of protein. Protein synthesis begins with the copying of the genetic information from DNA into a messenger RNA (mRNA) then mRNA is arrange amino acid sequence into a protein molecule.
The wildebeest population growth curve can be : Exponential, Linear, Logistic and Geometric rates. depending on the missing figure.
<u><em>Although your question is incomplete a general answer is provided above</em></u>
The growth of the wildebeest depends on the characteristic of the missing figure.( growth curve ) therefore the population can grow :
- <u>exponentially</u> if the growth rate is faster than the growing population size
- <u>linearly</u>; if the population increases/decreases at the same rate within a set time interval.
- <u>logistic</u> : If the populations starts growing slowly before an increase in growth rate.
- <u>geometric</u><u> </u>: If the population of the wildebeest increases at different ratios at discrete times.
Hence we can conclude that the wildebeest population growth curve can be described as Exponential, linear, logistic or geometric depending on the characteristic shown on the missing diagram

Answer:
Algae are single celled aquatic plants that need sunlight, food and carbon dioxide in order to thrive. So, the two elements that algae thrives on are nutrients and warm temperatures.
Explanation:
It is non-renewable because you can't get them back
