Answer:True
Explanation:
Nerve impulse must reach a certain threshold in a neuron before action potential can be generated to intiate conduction of action potential.
Therefore if mutiple impulses are generated and these are not upto thresholds , no matter how strong the stimulI are-NO ACTION POTENTIAL WILL BE GENERATED.
THIS IS ALL OR NONE PRINCIPLE
The all or none hypotheses can be best explain with flushing of the water closet after using it. If required volume of water is not pumped into the water closet storage above, no matter how long the handle is push, FLUSHING WILL NOT TAKE PLACE.Thus the threshold volume of water must be met.
<u>Given:</u>
Present population of bison = 3652
Maximum growth rate = 0.28
<u>To find:</u>
The population of bison after one year.
<u>Solution:</u>
The future population can be calculated with the help of the following formula,
where 
is the future population, 
is the present population, r is the growth rate and n is the number of years.
On substituting the given values in the formula we get,
Therefore, the population size of bison after one year is 4675. The park does not have to control the population because the growth rate is on an average scale.
Answer:
Their survival is correlated to water clarity because kelp, the main food of otters' prey (sea urchins), needs clear water to thrive.
Explanation:
Otters are extremely important organisms, also known as "<em>keystone</em>" species. They keep aquatic ecosystems healthy because they control other populations such as sea urchin populations that consume kelp, sometimes in excess.
For this reason, otters prefer inhabiting near the kelp, which generally grows in clear waters near shores. They also prey on crabs, marine snails, squid, etc. as they possess the ability to dive as deep as 250 feet.
Therefore, their survival is correlated to water clarity because kelp, the main food of otters' prey (sea urchins), needs clear water to thrive.
Answer:
A) Effect of findings on other family members would be most important factor.
Explanation:
Genetic research is done on human DNA to know the genes and environmental factors associated with certain disease.
Institutional review board (IRB) is the regulatory authority to protect the rights of subjects invloved in a resaerch.
The genetic reaerches usually involve families, so the researcher subjects and the result of research is related to all subjects that cause increased information flow between subjects and effect their decision to partcipate independently in research. Also, if the research involve therapeutic studies special precautions would be taken to choose the subject
