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:
TTCGT
Explanation:
since in DNA Adenine(A) pairs with Thymine(T) and guanine(G) pairs with cytosine(C) the complementary strand should be
T T C G T
Meiosis, is a special type of cell division of germ cells in sexually-reproducing organisms used to produce the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each paternal and maternal chromosome.
Answer:
1. Meiosis I
2. Tetrad
3. Tetrad
Explanation:
Crossing over refers to an event taking place in the cells undergoing meiosis cell division during which the exchange of material takes place. The process of crossing over takes place during pachytene of prophase I in meiosis I.
Crossing over takes place when the structure formed by the pairing of the four chromatids of the chromosomes called tetrad is formed. The formation of tetrad allows the exchange of genetic sequences, therefore, result in recombination.
The process of crossing over does not take place in the mitosis as the tetrad is not formed in the mitosis.
Thus, Meiosis I, Tetrad and tetrad are correct.
