Shell color in clams is thought to be controlled by three different genes (each with two alleles). Shell coloration runs a range
sergejj [24]

The correct answer is A. Quantitative traits

Explanation:

In genetics, quantitative traits refer to traits or phenotypes (observable traits) that depend on many factors including multiple genes and actions in the environment. These traits differ from other traits because the traits tend to be more diverse in a population. In the case presented, the shell color in clams is an example of a quantitative trait because this phenotype is the result of three different each and each gene contains two alleles which means the color depends on many factors. Additionally, as most quantitative traits there is a higher variation in the phenotype considering clams can have different hues.

How much force would is required to stop a 1200kg car in 2 seconds if the car is traveling at 22 m/s
Shalnov [3]
Force required = F = ?

mass of the car = m = 1200 kg

initial velocity of the car = Vi = 10 m/sec

final velocity of the car = 0

time required to stop the car = t = 20 sec

Using Newton`s 2nd law of motion;

F = ma ………………………(1)

as a = Vf - Vi / t , put this value in equation (1)

F = m ( Vf - Vi /t ) ………………(2)

F = 1200 ( 0 - 10 /20) = - 600 N

here Negative sign shows that external force is acting in opposite direction of the motion to bring it to rest.

we can also calculate this force by using the relation

Rate of change of momentum = net force acting on the object …………(3)

m Vf - m Vi / t = net force acting on the object

m (Vf - Vi / t) = F

1200 ( 0 - 10 /20) = - 600 N = F

so, net force acting on the object =F = - 600 N
