<h3><u>Answer;</u></h3>
There will be <u>4 different combination of chromosomes</u>
<h3><u>Explanation;</u></h3>
- <em><u>A diploid cell is a cell that contains two sets of each chromosomes; thus a diploid cell with two pairs of homologous chromosomes has four chromosomes.</u></em>
- <u><em>Gametes are produced through meiosis which is the type of cell division in which a parent cells divides into four daughter cells each with half the number of chromosomes as the parent, that is the cell are haploid.</em></u>
- Therefore,<em><u> </u></em><em><u>a diploid cell with two pair of homologous chromosomes will produce four haploid cells after meiosis each with two chromosomes.</u></em>
It makes sure they are in perfect condition for it to go through the cell cycle easier
Answer:
When helicase mutations occur, problems in DNA replication are found. The helicases are proteins that open the 2 strands of DNA to initiate the duplication, they are responsible for breaking the hydrogen bonds between the two DNA chains, thus separating the chains, also they have the function of repairing DNA mutations, if there is mutation in the gene that encodes them, various functions will be absent in the cell.
Answer:
The phloem carries important sugars, organic compounds, and minerals around a plant. Sap within the phloem simply travels by diffusion between cells and works its way from leaves down to the roots with help from gravity. The phloem is made from cells called 'sieve-tube members' and 'companion cells'.
The answer would be both!
