All three would decrease the size of the population of the organism. If an organism suddenly has a new predator, the organism's population will decline and it is likely that the members of the prey's population would disperse in an attempt to survive. Disease would just kill off the population in general, maybe the organism's population would distribute itself differently in order to avoid catching the disease. Competition would decrease the amount of food, water, and/or land available to the organism's population causing it to decrease or change habitats in an attempt to find another food source
Answer:
A presynaptic neuron knows when and how much of a certain neurotransmitter it has to release into the synapse by the frequency of the action potential.
Explanation:
Two nuerons connect to each other through synapse. When an action potential, or nerve impulse, arrives at the axon terminal, it activates voltage-gated calcium channels in the cell membrane, then the calcium which is present in hi highconcentration outside the neuron than inside, rushes into the cell. The Calcium then allows synaptic vesicles to fuse with the axon terminal membrane, releasing neurotransmitter into the synaptic cleft.
The nuerotransmitter than binds to the receptors at the post-synaptic cleft and causes the opening or closing of the channels, hence, depolarizing or hyperpolarizing the cells.This can produce a change in the membrane potential—voltage across the membrane of the receiving cell.
I think the answer is C) R I had this question and that was right for me hope this helps!
Answer:
There are number of methods for determining the fingerprints. However, most commonly used methods are:
- Photography
- Alternate Light Source
- Cyanoacrylate
Explanation:
Determination of fingerprints is an important method used in forensic science. There are generally three types of fingerprints that are to be determined, namely latent fingerprints, patent fingerprints and plastic fingerprints. There are numerous methods used for the determination of fingerprints. However, most commonly used methods are:
<u>Photography:</u> Photography is direct or straightforward method that is used to determine the patent fingerprints. The image is photographed in a high resolution with the help of forensic measurement scale used as a reference.
<u>Alternate Light Source Method:</u> In this method the light source or LED is used of a particular wavelength in order to determine the latent fingerprints.
<u>Cyanoacrylate:</u> Cyanoacrylate processing is also known as super glue method or fuming method, which involves exposure of cyanoacrylate vapors to the non-porous surface from where the fingerprints are to be obtained.
The time that processing plant proprietors required a loyal and trained workforce. Social conflict is the battle for organization or power in the public eye. Social conflict or gathering struggle happens when at least two on-screen characters contradict each other in social association, correspondingly applying social power with an end goal to achieve rare or inconsistent objectives and keep the adversary from accomplishing them.
