16. Explain why pollution caused the shift in the phenotypes of the peppered moth during the Industrial Revolution. (2pts)

Answer/Explanation:

Pollution during the industrial revolution caused trees to become covered with soot, making them darker. This dark appearance meant that the peppered moth, which usually had a light colour, was clearly visible against the tree. This meant it was easier for predators to identify. As a result, their numbers decreased because they were an easier target.

However, there was also a rarer form of the moth, which was dark in colour. These were initially very rare. However, because of the change in the tree colour owing to the industrial revolution, these moths were better suited to the environment, as they were more camouflaged against the dark tree. This meant it was easier for them to avoid predators, and so they were more likely to survive to reproductive age and pass on the genes that produce the dark colour.  This meant that the dark moths increased in number.

SIZIF [17.4K]

6 m/s

This type of collision is a <u>Inelastic collision </u>

Explanation:

We begin by finding the momentum of the initial train car;

Remember that momentum is given by the formulae mass (kg) * velocity (m/s)

Therefore;

Momentum = 6000 * 10

= 60,000 kg⋅m/s

The other car has zero momentum because;

4000 * 0

= 0

When the two train cars collide, the total momentum will be;

60,000 + 0 = 60,000

Therefore to find the velocity, well use the same formulae;

p = mv  whereby;

p – momentum

m – mass

v – velocity

60,000 = (6000 + 4000) * v

v = 60,000 / 10,000

v = 6

= 6 m/s

This is an elastic collision because we are assuming that no energy is lost in the collision. Most collisions, however, are not elastic but rather inelastic. In inelastic collision some of the kinetic energy is lost to the environment in some other form of energy such as heat energy.

Trees use narrow tubes to transport water upward. Which property of water allows the water to rise in these narrow tubes?
cluponka [151]

Answer:

C. Cohesion of molecules

Explanation:

Cohesion is the interaction of molecules of the same substance together. By the force of cohesion if two drops of water come together they form one. Water has high rates of cohesion due to hydrogen bonds.  

This phenomenon also called surface tension and is what allows small insects to stand on water.

Cohesion along with adhesion of water to the walls of the narrow tube generate what is called capillarity. This allows liquids to ascend inside the narrow tubes. As long as the cohesion is less than the adhesion, the liquid will rise until both forces are equal.

Which is the best explanation for why there is a continued need to develop new antibiotics to fight bacterial infections?
prisoha [69]

Answer:

Today, drug-resistant infections are a serious threat to people's health. Hundreds of thousands of lives are lost every year because of infections that can no longer be treated with existing drugs. Discovering new antibiotics, able to kill drug-resistant bacteria, is essential to saving modern medicine.
