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.
The Cell membrane-bound organelles, which carry out cell functions.
Nucleus, which contains the DNA cytoplasm.
The nucleus, the membrane-enclosed internal region that contains genetic material.
A very acidic level is 0 on the pH level. and a very basic pH level is 14. 7 on the pH scale is neutral. Anything lower than 7 is acidic, and anything higher than 7 is basic.
Answer:
During glycolysis carbon dioxide is released

11 and 12 seem to be right :) For 13, only organisms which are homozygotic for a certain gene (aa) express a recessive phenotype.
14. This dna exchange between the homologous chromosomes is called crossing-over.
15. geneticly linked or coupled, the phenomenon is known as genetic linkage
16. and 17. also seem all right :)
