1. <span>Abiotic and biotic factors are what make up an ecosystem. The ecosystem is how the living and nonliving things within the environment interact as a unit. The biotic factors present in an ecosystem are highly dependent on the abiotic factors that are present. Even slight changes to either factor can have a major consequence upon the system as a whole.                      that is 4 sentences

(b) Based on the data for the groups of cells cultured with 0.1% serum (groups 3 to 7), identify the groups(s) most likely to in
joja [24]

Answer:

Groups 4 to 7 are most likely to be undergoing the mitotic phase of the cell cycle.

Explanation:

Since the four proteins used p16,  p18,  p21, and  p27 are inhibitors of cyclin-dependent kinases (CDK), their absence indicates that the cell is undergoing mitosis - the cell cycle is regulated by CDKs. In the absence of these inhibitors, the cell cycle moves on forward. Because the bar for DNA replication is longer in the case for groups 4 to 7, it is indicative of the fact that these cells have gone through the mitotic phase.

Hope that answers the question, have a great day!

Water and minerals can follow three pathways to the vascular tissue of the root. Describe the three pathways.
Sunny_sXe [5.5K]
The answer is the apoplast, the symplast, and the transmembrane pathway.

1. The apoplast pathway occurs through cell walls and space between cells. So, water does not cross any cell membrane as it travels this pathway.

2. The symplast pathway occurs through the continuum of cytoplasm. So, water travels through plasmodesmata which connect cells.

3. The transmembrane pathway occurs across cell membranes. So, water enters the cell on one side of the membrane and exits on the other.
