Blood vessels that have thinner walls that are more likely to collapse when blood is withdrawn during a venipuncture are called veins.
Differently form arteries, veins are blood vessels with thin, less muscular walls. Veins have thinner walls because the blood pressure in them is much lower.
So, as a result of common intravenous injections (such as venipuncture), collapsed veins might occur. Veins are then temporarily blocked.

Answer:
<em>Complex multicellular organisms will suffer more, because vital differentiated cells that the rest of the organism requires will be lost.</em>

As the new producer will take bites of organisms, the complex organisms will most likely be harmed more from such a mode of nutrition. This is because each part of a complex organism will be made up of vital differentiated cells which will be specialized to perform its function. Loss of such part will lead to certain permanent kind of disabilities in the complex organism.
Answer:
The correct answer is A. The two cerebral hemispheres are separated by the longitudinal fissure.
Explanation:
The longitudinal or intercerebral fissure is a deep cleft that divides the brain longitudinally into two hemispheres (the right and the left) joined together by the corpus callosum. Other fissures, such as the central sulcus, the lateral sulcus and the internal perpendicular fissure, divide each hemisphere into large cerebral lobes, which in turn have cerebral convolutions.
