Answer:
AA
Explanation:
Just like the ABO alleles, each biological parent donates one of their two alleles to their child. A mother who is Rh- can only pass an Rh- allele to her son or daughter. A father who is Rh+ could pass either an Rh+ or Rh- allele to his son or daughter. This couple could have Rh+ children (Rh- from mother and Rh+ from father) or Rh- children (Rh- from mother and Rh- from father).
A person shall consume at least 750
mg of sodium ion daily to remain in electrolyte balance if he/she loses 750 mg/day
of sodium in urine, sweat and feces. Electrolyte is a substance that
can carry electrical current across cell membranes.
<u>Answer</u>: C. competency and proficiency
<em>Competency and proficiency’ guiding principle of forensic science states that a forensic scientist should be committed to lifelong learning.
</em>
<u>Explanation:</u>
A forensic scientist should be well aware of the <em>new technologies</em> and should have the expertise in using this new technology and equipment. The seriousness of the role that a <em>forensic scientist</em> is engaged in makes it necessary for him to be a continuous learner throughout his lifetime.
<em>Professionalism guiding principle</em> explains the need for a forensic scientist to remain impartial and conduct fair examinations. Clear communication principle mentions the importance of accuracy and clarity in a <em>forensic science report.

Answer:
The function of catalase is to protect cells from toxic effects by some reactive chemicals, such as hydrogen peroxide.
Explanation:
As a result of the metabolism, each organism causes some chemical substances to be produced, for example, hydrogen peroxide. Catalase catalyzes the reaction, decomposing hydrogen peroxide to compounds less dangerous for cells, for example, in water and oxygen. In the following reaction the function of catalase is shown:
2H2O2 -----------> 2H20 + O2
42% of rabbits in the population are heterozygous for the mutant Sp1 allele
Hardy-Weinberg equilibrium
- Assume that p is the frequency of the dominant allele
- p² is the frequency of the organisms with homozygous dominant genotype
- Assume that q is the frequency of the recessive allele
- q² is the frequency of the organisms with homozygous recessive genotype
- 2pq is the frequency of the organisms with heterozygous genotype
- p+q = 1
According to the question, 900 out of 10000 rabbits are homozygous recessive
- This implies that q² = 900/10000= 9/100= 0.09
- So, q = 0.3
- The frequency of the recessive allele is 0.3
- p = 1-q = 1-0.3= 0.7
For organisms with heterogenous genotype, their frequency is 2pq
2pq= 2 x 0.3 x 0.7 = 0.42
In terms of percentage, 0.42x 100% = 42%
Therefore, 42% of rabbits in the population are heterozygous for the mutant Sp1 allele.
