Answer:
Four daughter cells are produced each with 40 chromosomes. The daughter cells would exhibit genetic variations and would not be genetically identical to each other.
Explanation:
Meiosis is a cell division that forms four daughter cells from one parent cell as two sequential division meiosis I and meiosis II do not include any DNA replication between them. Crossing over during prophase-I of meiosis-I includes the exchange of genetic segments and occurs between the homologous chromosomes. It produces new gene combinations in the daughter cells which were otherwise not present in the parent cell.
Since there is no DNA replication between meiosis I and meiosis II, the daughter cells have half the number of the chromosomes compared to the parent cell. This occurs as homologous chromosomes move towards the opposite pole during anaphase I.
Therefore, a parent cell with 80 chromosomes will make a total of 4 daughter cells by meiosis. Each daughter cell would have 40 chromosomes. These daughter cells would have some new gene combinations and would be genetically dissimilar among themselves.
Answer:
C. Abrasion
Explanation:
Rusting, isn't caused by friction.
Dissolving isn't caused by friction either.
Neither is exfoliation.
^^ By the process of elimination we can conclude that the answer is in fact C, abrasion! Hopefully this helps! I hope you do well!
The sugar that is produced in photosynthesis is a glucose.
- Glucose can be used to provide energy for cellular activity.
- Excess of glucose is transformed into starch. Starch is transported into storage organs.
- Glucose can be transformed into cellulose, pectin, and chitin. These molecules are structural materials for the cell walls.
- Fats and amino acids can be formed from glucose. These molecules can serve as structural materials or can be stored.
I think the answer would be A , break the darkness period with a flash of light for some time so that the plants can bloom all year round.
Answer: creates genetically identical offspring, organism doesn’t have to waste energy to find a mate organism, requires the contribution of a single parent.
Explanation: While asexual reproduction only involves one organism, sexual reproduction requires both a male and a female.
Some plants and unicellular organisms reproduce asexually. Most mammals and fish use sexual reproduction.
Asexual Reproduction Sexual Reproduction
