The correct answer is choice B. Nondisjunction.
Nondisjunction disorder occurs when either the homologous chromosomes or the sister chromatids fail to disconnect properly during cell division. This failure results in daughter cells with an abnormality in chromosomes.
I hope this helps you and have an awesome day!! :)
Explanation:
an individual animal, plant, or single-celled life form.
A biotic factor can limit growth because for an example, if lions eat all of the zebras (for an example), what will other carnivores eat? There will be competition for food.
The correct answer is adaptive
radiation.
Adaptive radiation is the process by which a single specie or
single ancestral lineage, goes through several or various speciation processes and
then become adaptively specialized to a specific or particular environmental or
ecological place.
Answer:
1.Sea urchins are powerful primary consumers in the kelp forest. 2. Kelp is the producer in the kelp forests. 3. Bat star are omnivores and scavengers and at the end of the food web are tertiary consumers. 4 Phytoplankton are primary producers. 5. Zooplankton is a primary consumer in the food web.
Explanation:
1.Sea urchins are powerful primary consumer in the kelp forest because they are needed to keep the kelp anchored to the bottom of the ocean and algae . 2. Kelp is the producer in the kelp forest kelp forests provides an ecosystem for many organisms from the sea floor to the surface and provides shelter for many forms of sea life. 3. As a scavenger bat star is important in the ecosystem helping clean dead animals, and algae from the seafloor, the bat star keeps the seafloor healthy. 4. Phytoplankton are accounted for about half of photosynthesis on the planet, which makes them an important producer of oxygen, and serves as food source for smaller sea organisms, they consume carbon dioxide that would otherwise dissolve in the sea water making it more acidic. 5. Zooplankton are the animal like primary consumers of plankton community they also provide the base for the entire food web also if plankton disappeared it would increase the levels of carbon in our air.
