Answer:
1.
mRNA - Messenger RNA: Encodes amino acid sequence of a polypeptide.
tRNA - Transfer RNA: Brings amino acids to ribosomes during translation.
rRNA - Ribosomal RNA: With ribosomal proteins, makes up the ribosomes, the organelles that translate the mRNA.
2.
Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes.
3.
During translation, which is the second major step in gene expression, the mRNA is "read" according to the genetic code, which relates the DNA sequence to the amino acid sequence in proteins. Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code). The mRNA sequence is thus used as a template to assemble—in order—the chain of amino acids that form a protein.
Explanation:
Q1. The answer is <span>c. a mechanism of evolution.
</span>
Natural selection is the differences in survival and reproduction as the consequence of differences in phenotypes. According to Darwin's theory of evolution, natural selection is the only factor that affects a frequency of different variations and it is the only mechanism of evolution.
Q2. The answer is c. interactions between individuals.
Organisms interact with other organisms or abiotic factors in some system. The interaction <span>between individuals affects their regular distribution. For example, if two groups are in competition for resources, to maximize resource utilization, they will probably live in different areas or will defend territory. Also, some symbiotic organisms are expect to be distributed similarly.</span>
Answer:
sporogony
Explanation:
Based on the information provided within the question it can be said that the process that is being described in this scenario is called sporogony. This term refers to the asexual process of the formation of spores in some different sporozoans which contain sporozoits which is caused from the encystment and succeeding splitting of a zygote.
Answer:
The correct answer is - option c.
Explanation:
Benedict test is used to test the presence of reducing sugar in a sample. If the benedict solution turns in red or orange color it means there is a presence of glucose as it is a reducing sugar. So, this test result shows that there no reducing sugar in the sample as it is blue.
Lugol test is the test to see if the sample has starch in it or no by turning in to blue color, in this result, it is orange in color which suggests that there is no starch available.
A Biuret solution is used to test for the availability of protein in a particular sample, purple or pink color is the representation of the presence of protein. There is no protein as per result
Sudan red test is used to test the presence of TGA, lipids, or lipoproteins in a sample by reacting with it and turn in to red color. The absence of the lipids shows no change as it is shown in this test.
Thus, the correct answer among these options is - option C.
