Answer:
The correct answer will be option-a synergist
Explanation:
In the musculoskeletal system, the muscles to produce a movement work in group or pairs like hamstrings and quadriceps or biceps or triceps. The muscles which work is known as an agonist or prime mover.
The muscle which helps prime mover by moving in the same direction and at the same time is known as synergists. The synergists produce a similar motion as the prime mover and also stabilizes the joints which hold the position for smooth movement of agonist.
Thus, synergist is the correct answer.
T
Answer:
D 2 million years is the answer
Explanation:
Answer:
A. Populations were separated through geographical isolation.
Explanation:
Species X and species Z belong to the domain.
Answer: Option A.
<u>Explanation:</u>
Species which belong to the same domain, they also belong to the same kingdom and also to the same phylum. These species are very similar to each other and can also produce offspring together.
In the information given, species X and species Y belong to the same domain. The next column says that the species Y and species Z also belong to the same domain. So species X and species Z will also belong to the same domain.
Answer:
Whorl-1- petals
Whorl-2- petals (mutant)
Whorl-3- carpels (mutant)
Whorl-4- carpels
Explanation:
ABC model of flower explains the role of various genes in the formation of a flower from the shoot. Each gene forms a particular structure of a flower in the following manner:
1. A gene -sepals. (Whorl-1)
2. A + B- Petals (Whorl-2)
3. B+ C - stamens (Whorl-3)
4. C- carpels. (Whorl-4)
If a flower lacks the B gene, the effect will be observed in the phenotype in which B gene is involved that is in the formation of petals and stamens or whorl 2 and whorl 3.
The flower will produce
whorl-1- petals
Whorl-2- petals (mutant)
Whorl-3- carpels (mutant)
Whorl-4- carpels
