Answer:
The nucleus contains the protons and neutrons which takes up most of the mass of the atom.
this would be Prokaryotes because bacteria are single celled organisms
Answer:
D. 100%
Explanation:
In humans, males have only one copy of the X chromosome in their cells. Therefore, human males express all the X-linked genes present on their X chromosomes irrespective of the recessive or dominant nature of the allele. This occurs since males do not have one more copy of the X chromosome to carry another allele for the gene. So, all the X-linked alleles present on the X-chromosomes of the human males are expressed.
For example, human males with genotype X^cY and X^hY express colorblindness and hemophilia respectively. Though, human females express these recessive X-linked disorders in homozygous genotype only.
Answer:
Smaller muscle groups with a similar functional ability might include the antagonist major which acts as synergist in producing the same action as the agonist.
example : the biceps and triceps muscles of arm, work together as agonist and antagonist respectively.
The biceps helps to lift up or flexes the forearm and the triceps helps to extend it.
Explanation:
many muscles work together to make an action happen.
the muscle who is involved in an action principally, is known as prime mover or Agonist muscle.
Antagonist muscle does the opposite action of the agonist muscle.
antagonist also helps in-
- maintaining the body posture or position.
- controls the rapid movements.
like, to move a bone , the muscles attached to it work together to make a movement happen. like- to lift up a arm, agonist or prime mover muscles helps to lift up or flex the arm and the antagonist or synergist muscle helps to extend it.
