Exercise is very vital to the body,it a form of physical activity.the sole aim of excercise is to maintain stamina, flexibility,keep fit and be overly healthy and well.
When we excercise, our heart rate increases and then it returns to the normal rate when with rest,when we take a break.there is reflection of vasoconstriction in the fingers as the blood is shunted to only the exercising muscles because it is noted that the pulse amplitude of the heart is always small after excercise and and increases slowly during recovery.
The amount of blood the heart pumps in a minute,that is the amount of blood ejected by the contraction of the left ventricle into systemic circulation increases when we are exercising and resistance to blood flow by skeletal muscles decreases.the blood vessels will try to adapt to the condition (exercise) inorder to control blood flow and as well meet energy demands.
When we finish exercising,our body temperature increases which will inturn cause increase in the pulse rate and the blood in our body makes way to our skin,hands and legs inorder to clear off the energy that was generated by the body(muscles) during exercise
Answer:
AB, aB, Ab
Explanation:
Man has blood type B so could be BB (homozygous dominant) or could be Bb (heterozygous)
Woman has blood type A, so she could be AA (heterozygous dominant) or Aa (heterozygous)
Now, we need to make a separate cross for woman with AA, man with BB and we get children of all AB
Then we can make another cross for genotypes Aa and BB, and we get AB and aB
We can continue this for AA,Bb and for Aa,Bb
<h2>Answer:</h2>
The correct answer is B which is codominance.
<h3>
Explanation:</h3>
- One allele of a gene for a trait can be dominant or recessive according to the simple genetic phenomenon.
- But there are some exceptions Like both allele can express them dominantly producing an offspring having both forms of that trait.
- While in incomplete dominance, dominant allele is unable to expresses itself completely and a phenotype between dominant and recessive trait is produced.
- Hence in the problem, offspring have both colors of fur from two parents, so it is codominance.
