Absorbing water from the soil
Xylem is transport tissue found in vascular plants. The function xylem is to transport water from the roots to shoots. It is also used to replace the water loss during transpiration and photosynthesis. The xylem sap has water and inorganic ions . The transport of water is done true passive process. Transporting water to the top of the tree becomes difficult that is why xylem is also condsidered to limit the height of trees
A) no. the man can’t be a carrier
b) his father
c) no. the colorblindness has to show up on both X and Y chromosomes to be colorblind. So if the mother is not colorblind nor a carrier, then most likely it won’t happen since it’s a recessive gene.
Answer:
A cell that has duplicated chromosome cannot be in<u> G1 phase.</u>
Explanation:
- G1, G2 and S phase are the divisions of the interphase i.e. the resting phase of the cell cycle.
- A cell cycle has two phases; interphase and M-phase.
- During interphase the cell grows and in M-phase it divides.
- G1 is the Gap between the M-phase and the S-phase.
- G2 is the gap between the S phase and M phase.
- DNA replication is confined to the S part of interphase.
- Since G1 phase comes before the S phase , we can say that a cell that has duplicated chromosome cannot be in G1 phase.
