Fragmentation is the breaking of the body into parts and then the organism develops all the parts of the body. The fragmentation is the type of reproduction in lower organisms. The fragments which are produced can develop into new organisms.
Yeast lacks a membrane-bound nucleus. The onion skin cell has one
Passive transport<span> is a movement of </span>biochemicals<span> and other </span>atomic<span> or </span>molecular<span> substances across </span>cell membranes through <span>concentration gradients</span><span> without need of </span>energy<span> input. Unlike </span>active transport<span>, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in </span>entropy<span>. The rate of passive transport depends on the </span>permeability<span> of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane </span>lipids<span> and </span>proteins<span>. The four main kinds of passive transport are simple </span>diffusion<span>, </span>facilitated diffusion<span>, </span>filtration<span>, and </span>osmosis.
Cohesion causes water molecules to stick to each other. Cohesion is the attraction of like molecules
Answer:
c. Vasodilation causes arterial diameter to increase in the exercising skeletal muscle
Explanation:
Cardiac output increases blood pressure due to increased pumping action of the heart. To protect the blood pressure to rise to the fatal levels during exercise or any other activity of excessive muscle contraction, blood vessels are stimulated to dilate.
Dilation of arteries dissipates some of the blood pressure. The arteries with larger diameter have less blood pressure than the arteries with a narrow cavity under the conditions of the same cardiac output. Therefore, the dilation of arteries Dilation does not allow the blood pressure to rise to the harmful levels.
