Answer:
Anaerobic respiration.
Explanation:
Living beings used to respiration process to synthesize ATP. There are two types of respiration i. e. aerobic respiration and anaerobic respiration. in aerobic respiration, organisms synthesize ATP in the present of oxygen in very large amount while in anaerobic respiration, organisms produces ATP in the absence of oxygen but in very low concentration. So anaerobic respiration is the process used by organisms as an alternate method to produce ATP without oxygen.
Answer:
Gene. A segment of a DNA molecule (a sequence of bases) that codes for a particular protein and determines the traits (phenotype) of the individual.
Explanation:
Answer:
Therefore, 98% of the US population have no alleles for PKU
Explanation:
The Hardy-Weinberg equilibrium states that the amount of genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
The Hardy-Weinberg equilibrium is expressed quantitatively using a mathematical equation known as the Hardy-Weinberg equation. the equation is given below:
p² + 2pq + q² = 1
also, p + q = 1
Given a pair of alleles, S and s with A dominant and a recessive
where p is the frequency of the dominant allele in the population,
q is the frequency of the recessive allele in the population,
p² represents the frequency of the (SS) dominant genotype,
q² represents the frequency of the (ss) recessive genotype,
2pq represents the frequency of the heterozygous genotype
From the given question,
q² = 1/10000 = 0.0001
q = 0.01
from p + q = 1
p = 1 - 0.01 = 0.99
p² = 0.98
Therefore, 98% of the US population have no alleles for PKU
Answer:
D. physiological mechanisms are the basis of behaviors.
Explanation:
The example of the development of electric fields as part of the communication between some fish, shows the interrelation that exists between physiology and behavior. This physiological factor that fish have has an impact on their behavior. However, it is necessary to recognize that physiology does not act by itself, but needs to receive a stimulus from the surrounding environment.
This way of communicating is called electrocommunication, a fish generates through its physiology an electric field and a second individual receives that electric field with its electroreceptors.
Answer:
A. Repressor proteins can be activated and bind to regulatory sequences to block transcription.
