Answer:
Humans, chimpanzees, gorillas, orangutans, and their extinct ancestors form a family of organisms known as the Hominidae. Researchers generally agree that among the living animals in this group, humans are most closely related to chimpanzees, judging from comparisons of anatomy and genetics.
Explanation:
The appropriate answer is doing. decreased atmospheric water vapor leads to an increased greenhouse effect. This is not true because water vapor is a green house gas and increasing the levels of it in the atmosphere will lead to more warming. All the other answers represent appropriate feedback mechanisms associated with global warming.
Answer:
The genetic code is degenerate.
Explanation:
The genetic code is degenerate: there are 64 triplets of different codons (sequence of three bases of mRNA that codes for a certain amino acid) and 20 amino acids. That is, an amico acid can be encoded by more than one codon.
Each nucleotide only pairs with one nucleotide
Monoploid organisms reproduce asexually since they need to transmit all of their genetic material to their offspring. Diploid organisms, have 2 copies of their genetic material that differ slightly in their genes. Since the progeny gets half of the DNA from each parent, we have that new combinations can emerge; for example, if the mother is AA for some allele and the father aa, their offspring will be Aa, a new genotype. This might have different implications (for example, the recessive gene for thalassemia also provides resistance to malaria). Finally, during meiosis, there is also an event called crossover that increases the genetic variation of the offspring.
