Answer:

The temporary release of serotonin has been found to facilitate memory formation, and the temporary release of stress hormones has been found to facilitate memory formation.

Explanation:

Both serotonin and stress hormones have been proven to ease the formation of memory. Serotonin is found in the enteric nervous system, the central nervous system, and also stored in blood platelets; while stress hormones such as cortisol and adrenalin are produced by the adrenal gland when stimulated by either the hyphotalamus or the sympathetic nervous system.

Before a captive breeding program and subsequent reintroduction of the black-footed ferret it is believed that their total popul
irga5000 [103]

Answer:

a) 99.93%

b) 99.98%

Explanation:

Given that:

Total population size was only around 18 individuals ( for  black-footed ferret)

If the annual survival rate in the wild was 0.4%.

a)

What is the probability that all 18 would have died in a single year?

To find that; we multiply the annual survival rate in the wild with the total population; which is:

(0.4%×18) = 0.072%

Then; we subtract it from a total of 100% in order to determine the probability that all 18 would have died in a single year.

= (100.00% - 0.072%)

= 99.93%

b)

What is the probability that all 18 would have died in a single year if canine distemper was present?

Given that;

Because of the presence of canine distemper disease, the annual mortality rate might have been as high as 0.89.

To determine the probability; we have:

1 - Annual mortality rate = annual survival rate

1 - 0.89 = 0.11 %

Therefore, 0.11% of 18 individuals = (0.0011 × 18)

= 0.0198%

Probability that all 18 would have died in a single year if canine distemper was present = 100 - probability of annual survival rate

= (100 - 0.0198)%

= 99.98%

With the exception of the 12 cranial nerves, other major nerves exit the brain through the:
Oksana_A [137]
I think the answer should be medulla oblongata or foramen magnum.

The major nerves that leave brain should form a thick cord in the brain stem that called medulla oblongata. Medulla oblongata will pass a big hole in the base of the skull that called foramen magnum. Depends on what part the question asked(bone or tissue), it probably between those two options.

Natural selection is the process by which favorable traits tend to increase in frequency over time.
Nana76 [90]

Answer: The statement is true

Explanation:

Natural selection, as its name implies refers to the choice of certain favorable traits such as resistance to diseases, bigger fruit size etc above lesser favorable traits such as easy susceptibility to diseases, small fruit size etc.

Hence, nature allows the traits that will help living organisms survive best in their environment to be passed down to new offsprings while it eliminates all other traits.

Thus, the statement is true
