If a local population of a species goes extinct, which of the following outcomes is/are possible?a. Genetic variation may be los
insens350 [35]

Answer:

a. Genetic variation may be lost from the species as a whole

d. The overall adaptive prospects of the species may decline.

Explanation:

Genetic variations are heritable traits possess by the offspring from it progenitors. This makes the offspring to be an hybrid species because it has inherited the traits of both of his/her parents. In a local population setting goes to extinct, it might be as a result of genetic variation because these inherited variations comes in several ways, some might be adaptability to thrive in adverse weather  conditions, some production of specific hormones to combat the current state that its not suitable for them etc. so when a population shows a decline in genetic variation, such population is liable to extinction.

Also, when species can't cope with factors attached with adaptation to a particular ecosystem, (such as exhibiting camouflage in  time of danger, during dry season when food scarcity has increased etc) there will be decline in population of the species.

34kurt

Answer:

0.136 meter

Explanation:

The following equation will be used to solve this question -

P_{atm} + \frac{1}{2} (rho)v^2 + (rho)gh = P_{inject} + \frac{1}{2}(rho)v_{inject}^2 + (rho)gh_{injec}

P_{atm} -P_{injec} = 1400\frac{N}{m^{2} }

Velocity is zero.

Removing out the nullified terms from the above equation, we get -

(rho)gh = P_{injec}\\1050 * 9.8 * h = 1400\\h = \frac{1400}{1050*9.8} \\h = 0.136 meter

Hence,  top of the liquid in the bottle must be at a height of 0.136 meter.
