No thanks but thanks for asking anyway
In this, case we have that the egret is benefited by eating the insects that come out from the grass, nonetheless the antelope gets no benefit nor damage from this, so we can say that the correct answer is option A.
Answer:
At brain death.
Explanation:
If an individual is awake but not conscious of what is happening in the surrounding environments the person is in the vegetative state.Such individual could respond to certain reflexes as eye blinking,withdrawal of hands in response to touch, ability to sleep and wake up at normal sensations.However, cognitive functions and sensory responses which are related to emotions are not responded to.It is different from Coma in which the individual lacks ability to be aware of the environments and tom be awake or alert.
The vegetative state ends when brain deaths occurs.This is the state when all brain activities are lost permanently. Breathing seized,and contact with the external world is cut.Thus, the functions of the brain which were supported by artificial supports are lost because the parts of the brain which control breathing,heartbeat ,and blood pressure are dead. Therefore, the life supports can not stimulate them to life
Answer:
DNA sequences similarity among various organisms may be used to establish evolutionary relationship among living organisms. ... Organisms or animals whose DNA sequences are similar share common evolutionary origin.
Explanation:
Answer:
Energy released by the electron transport chain is used to pump H+ into <em>the mitochondrial intermembrane space</em> - Option D-.
Explanation:
There exist three proteinic complexes immersed in the internal mitochondrial membrane. These complexes have the electron transporters and the enzymes necessary to catalyze the electron transference from one transporter to the other. In complexes, I and III released energy by electrons provokes changes in membrane transport protein conformation. These changes make possible the protons transport against their concentration gradient, going from the mitochondrial matrix toward the intermembrane space. The protons concentrations difference between the matrix and the intermembrane space represents released energy.
