Answer:
Stem cells are special cells found in the human body which has the ability to change into different cell types and functions.
They are expensive in South Africa and are freezing the stem cells helps in the preservation of the cells for research works in the medicine. They are also used in the treatment of different illnesses which requires cells and tissue transplants.
Answer:
to preserve its stability.
to avoid cross contamination.
Explanation:
Biological evidence refers to all biological materials such as hair, tissue, bones, teeth, blood or other bodily fluids etc. These biological materials are collected from the site of crime. These evidences helps in finding the criminals. These biological evidences has to be kept at safe place in order to avoid contamination and preserve its stability so it can be used for solving the problem.
Answer: The correct answer for the blank is- has a Bb genotype, has brown eyes.
As per the information given in the question, blue eyes is a recessive ( depicted by small letter allele, b) trait and brown eyes is a dominant trait (depicted by capital letter allele, B)
A dominant allele ( like 'B' for brown eyes) always masks the expression of recessive allele ( like 'b' for blue eyes).
Heterozygous individual means a particular trait possesses both the alleles ( that is dominant and recessive allele) in the genome, which will produce a dominant trait.
The possible genotypes for brown eyes are 'BB' ( homozygous dominant) and 'Bb' (heterzygous dominant) whereas for blue eyes is 'bb'.
Thus, heterozygous individual has a Bb genotype and will produce brown eyes.
