If we were to compare the cells in the plant leaves to the cells in the plant roots, we would expect the leaf cells to contain many more a) chloroplasts. b) leucoplasts. c) nuclei. d) ribosomes.

A)chloroplasts.

Explanation:

We would expect the leaf cells to contain many more chloroplasts. The leaf is the main site of photosynthesis. Chloroplasts contain chlorophyll, a pigment used to collect sunlight which is converted to glucose during photosynthesis.

a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.  

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.  

many phylogenetic trees have a single lineage at the base representing a common ancestor. a lineage that evolved early from the root and remains unbranched is called basal taxon. when two lineages stem from the same branch point, they are called sister taxa.
