What are three mechanisms for reproductive isolation? Which Mechanism isolates two populations of similar frogs with different m

ating calls?
Physics

saul85 [17]3 years ago
4 0
The mechanisms of reproductive isolation are:
1) Habitat isolation
2) Behavioral isolation
3) Mechanical isolation
4) Gametic isolation
The isolation happening here is behavioral isolation, because their different behavior patterns prevent the frogs from breeding.

What is the speed of a transverse wave in a rope of length 2.00 m and mass 60.0 g under a tension of 500 n?
drek231 [11]

The formula we can use in this case would be:

v = sqrt (T / (m / l))

Where,

v = is the velocity of the transverse wave = unknown (?)

T = is the tension on the rope = 500 N

m = is the mass of the rope = 60.0 g = 0.06 kg

 l = is the length of the rope = 2.00 m

Substituting the given values into the equation to search for the speed v:
v = sqrt (500 N/(0.06 kg /2 m)) 
v = sqrt (500 * 2 / 0.06) 
v = sqrt (16,666.67) 
<span>v = 129.10 m/s</span>

What mindset do you believe Einstein had while alive and what do you think the key component or constant action was for Einstein
grandymaker [24]

Albert Einstein had a growth mindset due to innovative nature.

<h3>What mindset do you believe Einstein had?</h3>

Albert Einstein had a growth mindset because he did not give up when he face failure. He was very good in math and science but did not get into the school. The reason behind is that Einstein is different from other students. The key component or constant action was focus and devotion to work for Einstein throughout his "miracle year".

So we can conclude that Albert Einstein had a growth mindset due to innovative nature.

Which of the following does not affect the rate of solubility
lions [1.4K]

Answer:

Weight

Explanation:

Weight does not have any effect on solutbility.

For gases their solubility relies a lot on pressure exerted. At higher presure, gases dissolves more readily than ever. The relationship between solubility and pressure is a direct one.

Higher surface area facilitates the rate of a reaction and in essence, helps to dissolve more solute. Surface area exposes a solute to the action of more solvent which would aid solutbility.

Temperature has a high effect on solubility. An increase in temperature would make more solute dissolve in it.

A 5 kg box is sliding across a level floor. The box is acted upon by a force of 27 newtons east and a frictional force of 17 new
Juliette [100K]

Answer:

The acceleration of the box is 2.

Explanation:

According to Newton's second law of motion, the acceleration of any object will be directly proportional to the net unbalanced force acting on the object and inversely proportional to the mass of the object.

Net force = Mass × Acceleration

So Acceleration = \frac{Net force}{Mass}

Since in this case, the box is experiencing a force from east of magnitude 27 N and resisting force of about 17 N from west. So the net force will be the difference of acting and reacting force.

Net force = 27-17 = 10 N.

Thus, Acceleration = \frac{10 N}{5 kg}

So 2 m/s^{2} is the acceleration of the box. Thus the magnitude of acceleration of the box is 2.
