The moths that would be favored by natural selection would depend on the prevailing environmental conditions and the selective pressures acting on the population.

In the classic example of the black peppered moth (Biston betularia) during the Industrial Revolution in England, the dark-colored (melanic) form of the moth became favored by natural selection. This is because, during that time, industrial pollution caused widespread pollution and the darkening of tree trunks due to soot and smoke.

The dark-colored moths were better camouflaged against the darkened tree trunks, which provided them with a survival advantage. As a result, they were more likely to survive and reproduce, passing on their dark coloration genes to the next generation.

Over time, the population shifted towards a higher proportion of dark-colored moths.

The given statement is "To help regulate body calcium levels, bone has two reserves. The disadvantage of the stable reserve is that it:". is that "it cannot quickly release calcium into the bloodstream when it is needed.

"Therefore, the complete explanation is as follows:Bones have two stores to help control calcium levels in the body. The labile reserve consists of bone tissue that is readily accessible to the bloodstream, whereas the stable reserve is composed of bone tissue that is difficult to get to. The stable reserve is structurally more robust and less prone to remodeling than the labile reserve, which is more delicate and is continually being rebuilt or broken down.

Because the labile reserve is so dynamic, it is easier for bone tissue to release calcium into the bloodstream when it is required than the stable reserve.However, the disadvantage of the stable reserve is that it cannot quickly release calcium into the bloodstream when it is needed. As a result, the labile reserve acts as a rapid response mechanism to maintain serum calcium levels in the blood within the normal range. In a healthy person, blood calcium levels remain within a narrow range, which is essential for the proper functioning of various organs and tissues in the body. Thus, the disadvantage of the stable reserve is that it cannot quickly release calcium into the bloodstream when it is needed.

Explanation:

The tension in the rope is calculated as 33.7 N.

Weight of sled and fossil, w = 972 N Inclination angle of slope, θ = 19.8°

Speed of sled, v = 1.92 m/s

Coefficient of kinetic friction between sled runners and snow, μ = 0.107

To find:

Tension in the rope, T The forces acting on the sled are the gravitational force (Fg), the normal force (Fn) and the force of friction (Ff). The normal force is perpendicular to the slope and equal to the component of the gravitational force perpendicular to the slope. The force of friction is parallel to the slope and opposite the direction of motion.

The net force acting on the sled is given by the expression:

F net = ma

Since the sled moves with constant velocity, a = 0.

Therefore, F net = 0. F net = Fg sinθ - Ff = 0⇒ Fg sinθ = Ff

Since the speed of sled is constant, work done by tension in the rope is equal to work done by frictional force.

Hence, T = Ff = μFn

Where F n = Fg cosθ = w cosθ

Putting all the values,

T = μw cos θ sinθ= sin 19.8°cos 19.8°= 0.3365T = 0.107 × 972 × 0.3365T = 33.7 N

The rope is 33.7 N. The given problem is related to the tension in the rope. The tension in the rope is calculated as 33.7 N.

To bring down the fossil safely down the slope, the tension in the rope is 33.7 N. The gravitational force is acting perpendicular to the slope and the force of friction is acting parallel to the slope. The normal force is the component of gravitational force acting perpendicular to the slope. The sled moves down the slope with a constant velocity. The force acting on the sled is equal and opposite to the force of tension in the rope. The force of friction is given by the expression,

Ff = μFn,

where Fn = Fg cosθ = w cosθ.

Therefore, the tension in the rope is calculated as 33.7 N.

To bring down the fossil safely down the slope, the tension in the rope must be 33.7 N.

One of the earliest adaptations made by hominids was bipedalism, and there are several theories as to how the human ancestors acquired it. One of them claims that after a group of our ancestors started living in Savannah habitats, bipedalism emerged (open areas covered with grasses). The Savannah lineages didn't have many trees to climb, so the upright posture let them see predators in the distance. Other lineages remained in the forests, where they could use the treetops and branches for protection and to collect food.

The second theory links the use of tools to the evolution of human bipedalism. The two forelimbs are free to explore the environment, aid in the use of tools, and even gather food while moving because a species does not move on all four limbs.

With this knowledge, we can conclude that bipedalism gave the human race a free arm to build technology and allowed them to move more slowly while walking, among other benefits.
