Answer: Option B.
B. The chromaphore retinal absorbs a photon of light, causing a double bond in retinal to isomerize from trans to cis configuration.
Explanation:
Bacteriorhodopsin is a protein used by archaea or half bacteria that pumps proton across membrane by using the light energy from sun to move protons across membrane. It is found in purple membrane of archaea cells which is known as two dimensional crystalline patches.
It captures photon energy through chromophore retina which is covalently bound and transporting the photons against their electrochemical gradients from the cytoplasm to the extracellular space.
Answer:
Motor neurons:
A. Function:
It relay messages coming from the brain or spinal cord to the muscles or organs.
B. Structure:
●Presence of long axons due to long distances the signals have to travel to the muscle its stimulating.
●It's myelinated, to assist the signal in travelling long distances as soon as possible.
Sensory neurons:
A. Function: its sensory receptors respond to stimuli by converting it into an electrical signal to the brain or spinal cord.
B. Structure:
●Presence of long dendrites / axons
● its myelinated
●since it's found in the middle of the neuron it forms ganglia that unites in the spinal cord and aid in involuntary reflexes.
Interneurons:
Structure:
● shorter than motor or sensory neurons
● has branches, a lot of branches consisting of axons and dendrites off the cell body to enable multiple simultaneous between neurons
● It's body is partially myelinated.
●occurs in large clusters of neurons to compensate for its partial myelination to speed up the signal
Answer:
Option C, he lost both sensory and short-term memory
Explanation:
Sensory memory is basically the information received by the five sense organs and also the instruction given by brain to the respective sense organ.
This sensory memory keeps storing and is collectively referred to as short term memory.
Since Chuck Wildlee was unable to remember how many balls and strikes the batter had. In past he would have perceived this information through eyes which should have been part of sensory memory and later the part of short term memory.
Thus, it can be said that Chuck Wildlee lost both his sensory memory and short term memory
Hence, option C is correct
Answer:
C) both an aggregate fruit and an accessory fruit
Explanation:
When several flower ovaries or receptacle of a flower with many separate carpels joins together they form aggregate fruit. Each ovary has a single ovule that converts into a seed after fertilization.
Aggregate fruit can be formed without the involvement of accessory parts called true aggregate fruit or with the involvement of additional floral parts called accessory aggregate fruit. Strawberry is also an accessory aggregate fruit because the different ovaries in the strawberry develops into achenes over the surface of flower receptacles.
