The answer is option 3 because people with sickle cell anemia have abnormal hemoglobin molecules that is called hemoglobin S, which stick to one another and form long, rod-like structures. These structures cause red blood cells to become stiff and shape into sickles or crescent moons.
Hope that helps!
The answer is <span>D.A mouse lies still when it sees a cat, which helps it evade detection by a predator.
Behavioral adaptations are thing organisms do to increase their chance to survive and reproduce. This is, actually, how organisms react in response to a threat. For example, animals could move from place to place, or imitate something they are not (mimicry). The example of mouse's behavioral adaptation is when mouse sees a cat, it lies still in order to evade it. Mouse changes its behavior to survive.</span>
The answer is <span>5.2 × 10-2 newtons.
To calculate this, we will use Coulomb's Law:
</span>F =
![\frac{k * Q_{1} * Q_{2} }{ r^{2} }](https://tex.z-dn.net/?f=%20%5Cfrac%7Bk%20%2A%20%20Q_%7B1%7D%20%2A%20%20Q_%7B2%7D%20%7D%7B%20r%5E%7B2%7D%20%7D%20)
where F is repulcive force, k is constant, Q is charge, r is distance between charges.

If:
</span>
![Q_{1}](https://tex.z-dn.net/?f=%20Q_%7B1%7D%20)
=
![Q_{2}](https://tex.z-dn.net/?f=%20Q_%7B2%7D%20)

r = 5.0 ×
![10^{-1}](https://tex.z-dn.net/?f=%2010%5E%7B-1%7D%20)

Then:
<span>
![F = \frac{5.0* 10^{-1} \frac{N* m^{2} }{ C^{2}} * 1.2 * 10^{-6} C * 1.2 * 10^{-6} C }{(5.0* 10^{-1} m)^{2}}](https://tex.z-dn.net/?f=F%20%3D%20%5Cfrac%7B5.0%2A%2010%5E%7B-1%7D%20%5Cfrac%7BN%2A%20m%5E%7B2%7D%20%7D%7B%20C%5E%7B2%7D%7D%20%2A%201.2%20%2A%2010%5E%7B-6%7D%20C%20%2A%201.2%20%2A%2010%5E%7B-6%7D%20C%20%7D%7B%285.0%2A%2010%5E%7B-1%7D%20m%29%5E%7B2%7D%7D%20)
</span>⇒
![F= \frac{9 * 1.2 * 1.2 * 10^{-3} N }{25* 10^{1} }](https://tex.z-dn.net/?f=F%3D%20%20%5Cfrac%7B9%20%2A%201.2%20%2A%201.2%20%2A%20%2010%5E%7B-3%7D%20N%20%7D%7B25%2A%2010%5E%7B1%7D%20%7D%20)
