Answer:eukaryotic cells
Explanation:One of the main differences between prokaryotic and eukaryotic cells is the nucleus. Also prokaryotic cells lack an organized nucleus while eukaryotic cells contain membrane-bound nuclei (and organelles ) that house the cell's DNA and direct the synthesis of ribosomes and proteins.
The answer is because when the heart pumps blood in the artery during systole it counteracts the resistance provided by the blood vessels. This requires high pressure that is provided by the force of ejection due to the contraction of the ventricles. On the other hand, the pressure is lowest during diastole which is the ventricular filling of blood. There is low resistance in the blood vessels and the arterial wall pressure declines until the heart starts to contracts again.
Answer:
c. Adaptive radiation occurs in the presence of competitors.
Explanation:
Adaptive radiation is a process of diversification in which new species are originated from an ancestral species due to changes in the enviroment or deu to pressures such as competition for resources that lead organisms to find new niches. For example, if there are many competitors for the same food source, that pressure could lead some organisms to look for a new food source, that, in turn, can lead to the adaptation of their body to the new food source. For example, bird beaks that were specialized for seeds can be adapted for insects.
