Answer:
a. occurs right before the best growing season
Explanation:
Seed dormancy prevents seeds from germinating in unsuitable conditions such as competing for light and water with other plants or being able to be eaten from a high population of herbivores species during certain seasons.
If a dormant seed is broken after prolonged cold treatment, then this cold part of the year occurs right before the best growing season for this dormant seed. The native habitat of the plant must have an undetermined and cold season that breaks seed dormancy.
Answer:The might likely die.
Explanation:
Phloem and xylem tissues are the major conducting tissues in plant. Xylem conduct ( transports) water and minerals salts from the soil through the roots to all parts of the plant while phloem conducts manufactured food from the leaves to other parts of the plant.
Now, if the phloem of a seed plant is damaged and not functioning well, the manufactured food will not get to other parts of the plant where it is needed or supposed to be stored.
If the plant is no longer getting these nutrients, its growth and development will be affected. It might lead to the death of the plant.
Answer:
The genotype of both parents is RrYy.
The possible types of gametes would be RY, Ry, rY, and ry.
The cross would produce offspring that can have one out of four types of phenotypes:
- Round and yellow seeds (1 RRYY+ 2 RrYY +2 RRYy + 4 RrYy) = 9/16
- Wrinkled and yellow seeds (3 rrYy) = 3/16
- Round and green seeds (1 RRyy + 2 Rryy) = 3/16
- Wrinkled and green seeds (rryy) = 1/16
Thus, one out of 16 offspring would have wrinkled and green seeds.
Material in the cell nucleus made up of DNA and various kinds of protein is called chromatin.
B. Experiment 1, because it gave the same results every time
