Answer:
chitin
Explanation:
chitin is a complex carbohydrates, similar to cellulose, that makes up organic structure, such as the cell walls of fungi and exoskeletons of insects and other arthropods.
Layering is the most obvious feature of sedimentary rocks. The layers are piled one on top of the other.
Explanation:
Central dogma represents the pathway in which the information encoded in the DNA flows into proteins.
The DNA is made up of the nucleotide monomers in which the nitrogenous bases are present as one of the constituents. These bases are present in the sequence are transcribed into the RNA molecule through the process of transcription.
The nitrogenous sequences in this RNA molecule are then translated into the proteins through the process of translation during which the sequence is read in pairs of three called "codons". A specific amino acid is attached to the peptide when the codons are read by the translation machinery and a protein is formed.
These proteins could perform various roles in organisms from physical to biochemical and thus the physical traits are controlled by the DNA.
Answer: B
Explanation:
Photosynthesis uses CO2 and water to make oxygen and glucose.
6CO2 + 6H2O → C6H12O6 + 6O2 This is the chemical reaction that occurs. Products are on the right and we can see glucose and oxygen are formed.
Answer;
-Birth rate
Explanation;
-The birth rate is the total number of live births per 1,000 in a population in a year or period. For example; in one year, 35 giraffes are born to a population.
-A population is defined as a group of individuals of the same species living and interbreeding within a given area. Members of a population often rely on the same resources, are subject to similar environmental constraints, and depend on the availability of other members to persist over time. Scientists study a population by examining how individuals in that population interact with each other and how the population as a whole interacts with its environment.
