Answer:
Explanation:
Gregor Mendel showed his inheritance character in the garden pea plant. According to him, there are 2 alleles which are inheritable - dominant allele and recessive allele. The dominant allele is always dominant over the recessive one which is known as the complete dominance. When the offsprings have both recessive alleles it will show its character.
There are other characters present besides dominant and recessive. Such characters are known as Mendelian deviation as it does not obey Mendel's law of inheritance. e.g. codominance, incomplete dominance.
In codominance alleles, characters are blended and a new character has seen in the next generation. This new character is neither dominant not recessive, it is an intermediate character between the 2 characters.
e.g When the white and red flowers crossed pink flowers are formed along with red and white.
In the case of codominance, both alleles express their characters. Such phenotypic characters are known as codominance because both alleles are expressed in the offsprings.
e.g. When the red and white flower plants crossed the offspring flowers are red with white spots or the white with red spots.
Answer:
B) aorta to smaller systemic arteries to systemic capillaries to systemic veins to right atrium through the triscupid valve
Explanation:
Oxygenated blood from the right ventricle is pumped into the aorta. Aorta is the largest systemic artery that obtains oxygenated blood directly from the heart. Many systemic arteries get oxygenated blood from the aorta. Exchange of oxygen between blood and tissue cells occurs in systemic capillaries.
The deoxygenated blood from tissues is picked by systemic veins. The deoxygenated blood from systemic veins is delivered to the right atrium via vena cava. The blood is pumped from the right atrium to the right ventricle through the tricuspid valve from where it is carried to the lungs for oxygenation. The oxygenated blood from the left atrium is pumped to the left ventricle and finally into the aorta.
