Correct answer: A). The current hypothesis of the evolutionary relationships between organisms
The tree of life is a metaphor that expresses the idea that how life is related to ancestors. Charles Darwin first uses this in the modern biology. It is an evolutionary tree that depicts the relationship between various biological entity. It holds the data that are collected from RNA, DNA and protein analysis. It shows the current hypothesis about the evolutionary relationship among the taxa.
Hence, the correct answer would be option A.
B. Is characterized by four different zones.
The last suggestion is correct....when you have setes of rest in between workouts..you allow the lactic acid to seep into your muscles and ensure that the muscle protein is broken down properly.
Answer:
Catabolite repression
Explanation:
Catabolite repression is characteristic for prokaryotic organisms such as bacteria and this is the way to control metabolism.
It is called repression, because enzymes that are involved in other sugar's metabolism are inhibited (repressed). The system of catabolite repression have components such as:
- sensory systems-detects ratios of glycolytic intermediates,
- global regulators-control the expression of genes that encode for enzymes.
Answer:
% of wolves have normal fur.
Explanation:
Given , the allele for white fur is recessive and the allele for normal fur is dominant
Let "N" represents the allele for normal fur and "n" represents the fur for white fur.
As per Hardy Weinberg's principle, the frequency for dominant allele is represented by "p"
Given ,
Then frequency for dominant genotype will be "
"
So, Frequency for wolves with normal fur is

Percentage of the wolves with normal fur is
%
