Answer:

The options

A. the postzygotic barrier called hybrid inviability

B. the postzygotic barrier called hybrid breakdown

C. the prezygotic barrier called hybrid sterility

D. gametic isolation

The CORRECT ANSWER IS A.

A. the postzygotic barrier called hybrid inviability

Explanation:

Postzygotic barrier is a mechanism that hinders reproduction after fertilization and zygote development. Hybrid inviability occurs when a mating between two organism produces a hybrid that can't strive past the embryonic stages.

In Reduced Hybrid Viability there is a lower tendency to survive for individuals whose parents possesses incompatible genetics, which may have result from sexual union of these parents from varying species.

These two frog species in this case study can be separated through the mechanism of the postzygotic barrier called hybrid inviability.

A Chlorella cell viewed through a microscope is 0.00005 m wide when the magnification is 2000.
juin [17]

Answer:

0.0025micrometer.

Explanation:

To calculate the actual size of the image, the formula to be used is

Actual size=Image size÷magnification.

The image size is 0.00005 wide

Magnification is 2000

First, convert the image size to micrometer.

=0.00005 × 1000000

50micrometers.

Actual size= 50÷2000

Actual size = 0.0025

a 24 kg rock containing 3,528 j of potential energy rests upon the edge of a cliff how tall is the cliff
GenaCL600 [577]
Potential gravitational energy is computed with the formula:

PEgrav=mgh

Where:
PEgrav = Potential gravitation energy (J)
m = mass (kg)
h = height (m)
g = acceleration due to gravity (9.8m/s^2) 

Take note that acceleration due to gravity is a constant. 

All you need to do is put in what you know and solve for what you don't know. So your given is the following:
PEgrav = 3,528J
m = 24 kg
g = 9.8 m/s^2
Put that into your formula:
PEgrav=mgh
3,528J = (24kg)(9.8m/s^{2})(h)
3,528J = (235.2kg.m/s^{2})(h)
\frac{3,528J}{235.2kg.m/s^{2}} = h
15m=h

The height of the cliff is 15m.
