Upon crossing BB with bb, we will get a hybrid of Bb.
- Codominance is a phenomena in genetics where two alleles (different forms of the same gene) express themselves equally in an organism. As a result, characteristics linked to each allele are shown at the same time.
- The MN blood group system in humans is an illustration of codominance. M and N alleles control the MN blood type. Red blood cells from people who are homozygous for the M allele carry a surface molecule known as the M antigen. On their red blood cells, those who are homozygous for the N allele contain the N antigen. A heterozygote is a person who carries both antigens.
- (a) Genotype of blue scales fish will be BB.
- (b) Genotype of blue scales fish will be bb.
- (c) Genotype of blue scales fish will be Bb.
So, in this case B and b alleles will express equally.

Baroreflex is a reflex triggered when a baroreceptor is stimulated. In the human body, baroreceptors are found in the carotid sinuses and the sinus of the aorta. These receptors are stimulated during changes in blood pressure. Baroreceptors are sensitive to the stretching of blood vessels.
As blood pressure rises, baroreceptors transmit nerve impulses to the vasomotor center of the medulla oblongata, which is then inhibited. This results in vasodilatation of the blood vessels to reduce blood pressure.
Answer:
The correct answer is D
Explanation:
ATP is energy (starting from the sun) which is used within photosynthesis to form more energy/ATP.
Answer: Brain
Explanation:
The DTI technique is useful for examining the brain. It is a used to observe the neuropathology and associated treatment. It is used to examine the pathology of brain such as axonal damage, edema, inflammation, and iscemia myelination.
In the 1800s, Darwin explains the origin of species. As species originate through adaptation by natural selection.
Answer: Species originate through adaptation by natural selection
<u>Explanation:
</u>
The Origin of species through natural selection is a pioneering scientific effort of the British naturalist Charles Darwin in England. Darwin's theory is that organisms are gradually evolving through what is called "natural selection"
It is a process in which organisms change due to hereditary changes in physical or behavioural traits. Changes that allow the body to better adapt to its surroundings, help it survive and have more offspring.
