Answer:
50% green-seed individuals vs. 50% yellow-seed individuals.
Explanation:
Mendel is known as father of genetics. He explained the concept of dominance, the law of segregation and the law of independent assortment while working on pea plant.
Green seed color is recessive and yellow seed color is dominant. A pure green line seed plant (ss) is crossed with heterozygous plant (Ss). The cross is as follows:
Parents ss (green seed) × Ss (Yellow seed)
Gametes s S, s
progeny: Ss, Ss, ss, ss.
Here, Ss is yellow seed and ss is green seed.
50% green-seed individuals vs. 50% yellow-seed individuals are formed after the cross.
Thus, the correct answer is option (a).
Answer:
Genetic continuity is maintained by the Replication or Synthesis phase and the Mitosis phase of the Cell cycle.
Explanation:
- The Cell Cycle can be divided into the following phases,
- G0- Interphase.
- G1 - Growth phase.
- S - Replication or Synthesis phase.
- G2 - Second Growth phase.
- M - Mitosis.
- Of all the above phases, in the S phase the replication or doubling of the genetic material, that is, the DNA, occurs for equally distributing the genetic material to both the daughter cells.
- The M or the Mitosis phase is also essential to ensure that the distribution of the genetic material occurs accurately among the daughter cells.
- Hence, a genetic continuity is maintained across the generations of the cells.

passing traits onto offspring.
Explanation:
YES.
The thirst mechanism always underestimates fluid loss during work, in the heat and after work ends. Therefore you should take frequent drinks through out the work period. If you drink 250mililitres every 15 minutes, you can replace one litre per hour. if sweat rate is higher you will find it extremely difficult to keep up with fluid needs. During prolonged periods of work in the heat, weight loss exceeds 2 percent therefore the person should rehydrate before returning to work.
