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: Ocean salinity increases as ocean temperature decreases.
Explanation: Scientists have believed for many years that water pressure increases as water depth increases
Answer:
Proteins are responsible for the <u>mass </u>and <u>fat </u>of much of our bodies (and other organisms). The instructions for making protein are encoded in <u>DNA</u>. These genes provide the sequence of building blocks known as <u>nucleotides</u>. This string of amino acids then folds into different shapes. The structure of proteins determines what a <u>molecule </u>can do. Proteins contain carbon, hydrogen, oxygen, and nitrogen.
