Answer:
C
Explanation:
Volcanic eruption spews volcanic ash into the atmosphere that lingers and blocks out sunlight for months. This causes photoautotrophs to decrease in population numbers due to the inability to photosynthesize. This will negatively affect the heterotrophs that depend on the autotrophs for energy.
Answer:
B
Explanation:
There are usually dominant and recessive alleles. The dominant alleles mask the expression of the recessive allele. Therefore, whenever an offspring has a dominant allele of a gene, it will be expressed whether in homozygous or heterozygous form.
Answer:
B
Explanation:
A limiting factor is an element whose abundance affects the growth and distribution of a population of a species in an environment. In this case, increasing the levels of Nitrogen in the environment increases the population size and vice versa.
I took the test, and it said that the answer False is correct.
I hope this helps! Have a nice day :)
Igneous rock are classifies as either volcanic rock or plutonic rock.
Answer:
The plasmid that must contain the CD3y core promoter sequence is PCD3γ-15, and the most likely cause in variation is due to the differing regulatory sequences in the cell.
Explanation:
Answer:
False
Explanation: Heterotrophs benefit from photosynthesis in a variety of ways. They depend on the process for oxygen, which is produced as a byproduct during photosynthesis. Moreover, photosynthesis sustains the autotrophs that heterotrophs depend on to survive
