Biochemical- apart of the second defense system
Genetic drift happens when well-adapted organisms survive and reproduce more often than poorly-adapted organisms. <span>The statement that best sums up evolution is the change in a population through genetic variation over time. Natural selection may be through (1) differential reproduction, that is, not all organisms are able to reproduce to their fullest capacity because nature cannot simply sustain it and (2) acquire genes, that is heredity.</span>
-involves their factors and
subtests
-Quantitative Reasoning: the
ability to solve numerical problems
-Visual-Spatial Processing: the
ability to analyze visually presented information, including relationships
between objects, spatial orientation, assembling pieces to make a whole, and
detecting visual patterns
-working memory: the ability to
hold and transform information in short-term memory
-each of these 10 areas is
assessed by one to three specific types of items .
Answer: The transcription and translation process allows trna and rrna molecules to be used to synthesize wide variety of polypeptides.
Explanation:
DNA molecule is made up of information for coding proteins. This information is passed on the mRNA during a process known as transcription. Transcription is the first of many steps of DNA based gene expression in which a part of the segment of DNA is copied into RNA (especially mRNA) by the enzyme RNA polymerase.
Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language. During the process of transcription, a DNA sequence is read by an RNA polymerase, which gives a complementary, antiparallel RNA strand referred to as a primary transcript.
A large diversity among genes is followed by a large amount of various mRNA molecules. However, the ribosomes consist of rRNA, which is included in the process of translation. Translation is the process whereby ribosomes in the cytoplasm or ER synthesize proteins after the process of transcription of DNA to RNA in the cell's nucleus. The overall process is called gene expression.
The smallest of the three types of RNA is tRNA, which has only 75 to 95 nucleotides and has a role in bringing particular amino acids to the growing polypeptide. It can be concluded that mRNA contribute to the diversity of polypeptide molecules due to the fact that it carries an information about their synthesis.
Answer:
D
Explanation:
Because there has to be competition or one population wouldnt decrease and the other wouldn't increase due to survival and reproduction the population doesn't always have to be below the carrying capacity because it can also do it when its above and natural selection can act on traits determined by different alleles.
