Answer: yes
Explanation: since the bacteria is in the throat/tonsils the breathing of a person bc of the water in it can transfer if placed in mouth
Answer:
The ABO blood group represents the phenomena of Co dominance and the multiple alleles.
1. The cross between O A X AB results in the formation of progeny with the genotype OA ( A blood group), OB ( blood group), AA ( A blood group) and AB ( AB blood group). Their cross results in the B progeny.
2. The cross between O A X OO results in the progeny with A blood group ( AO, AO ) and ( OO, OO) and O blood group. Their cross results in the A progeny.
3. The cross between O A X B produce the children with genotype A, B, AB and O if the parent is OB.
4. The cross between O A X AB produces the child with the genotype OA, AA ( A blood group) OB ( B blood group) and AB (AB blood group). No child with O blood type is produced by the parents.
5. The cross between O B X B produce the children with genotype OO, OB,OB and BB if the parent is OB.
6. The cross between AB X AB results in the progeny with genotype AA ( A blood group) , AB, AB (AB blood group) and BB (B blood group). Their cross results in the progeny with A blood group.
The freezing point of water is zero degrees Celsius.
Answer:
Chromosomes
Explanation:
Multicellular organism are organisms that have more than one cells in their body. However, from the very beginning of every living organism including multicellular organisms, only ONE cell is required. In the case of multicellular organisms, this one cell undergoes division by mitosis to form other cells.
Since the cells divide by mitosis i.e 1 forms 2, 2 forms 4 etc.,. each of the cells are genetically identical to one another. Hence, this means that all the cells will contain the same number of chromosomes in their genome. For example, a dog as a multicellular organism has cells that emanate from one cell. If that one cell contain 39 chromosomes, all cells in the dog will also contain 39 chromosomes.
Answer:
D. Use the polymerase chain reaction.
Explanation:
<em>Option A is incorrect because subjecting the DNA to electrophoresis will only identify, purify or quantify the DNA.</em>
<em>Option B is incorrect because nucleic acid probes are only useful in detecting mRNA.</em>
<em>C is incorrect because amniocentesis is just a medical procedure involving the removal of amniotic fluid for the purpose of analysis.</em>
<em>Option E is not correct because restriction enzymes will only cut the DNA at specific points.</em>
The correct option is D. Polymerase chain reaction is a procedure in molecular biology that is utilized to amplify or multiply a copy of DNA.
