Light-skinned people generally have a greater proportion of which pigment in their skin?

Keratin

Pheomelanin

Eumelanin

Carotene

Answers

Answer:

Pheomelanin

Explanation:

Dark-skinned individuals produce more melanin than those with pale skin.

Light-skinned people typically have a greater proportion of pigment in their skin Pheomelanin, Dark-skinned persons produce more melanin than those with pale skin.Thus, option "B" is correct

What is the difference between pheomelanin and eumelanin?

Eumelanin is black or brown tint and pheomelanin is red or yellow pigment.

Individual who create lots of pheomelanin tend to have lighter skin, often because of freckling.

Freckles occur when melanocytes clump together. Melanocytes are generally scattered rather evenly in the skin.

Thus, option "B" is correct,  Dark-skinned individuals produce more melanin than those with pale skin.

3. It’s a hot, sunny morning in a coastal town in South Florida. Warm air is rising up from the land. Large, puffy clouds are forming overhead. Which way do you think the wind will be moving this afternoon, and what do you think will happen to the temperature?

Answers

Answer:

1. The lower the air pressure the faster the wind the higher the air pressure the slower the winds

2. When the heat of the air increases the density of the air decreases.

3. The air above the ocean will, therefore, be warmer and of low pressure than that over land which will be cooler and of relatively higher pressure. Winds will, therefore, blow seawards because winds blow from high to low-pressure systems.

If you were to start at the base of a mountain and climb it all the way to the top, how would the climate change?

A The climate would get colder and drier as you go up the mountain.
B The climate would get warmer and wetter as you go up the mountain.
C The climate would stay the same because you are in the same climate zone.
D The climate would be similar to a tropical climate zone as you go up the mountain.

Answers

Answer:
C
Explanation:
It’s easy

The climate would get colder and drier as we go up the mountain. So, the correct option is A.

What is the effect of altitude on the atmosphere?

When altitude increases, the amount of gas molecules in the air decreases, so the air becomes less dense than air closer to sea level, which is what meteorologists and climbers mean by "thin air". Thinner air exerts less pressure than air at lower altitudes.

Most of the gas molecules in the atmosphere are pulled closer to the Earth's surface by gravity, so gas particles are denser near the surface, so with more gas particles in a given volume, there are more collisions of particles and therefore more pressure.

Thus, the climate would get colder and drier as we go up the mountain. So, the correct option is A.

The ability to taste the chemical PTC is determined by a single gene in humans with the ability to taste given by the dominant allele T and the inability to taste by the recessive allele t. Suppose two heterozygous tasters (Tt) have a large family. What is the likelihood that their first child will be a taster

Answers

Answer:

75%

Explanation:

This question involves a single gene coding for the ability to taste the chemical PTC. The allele coding for the ability to taste (T) is dominant over the allele coding for the inability to taste (t). This means that an heterozygous individual will have the ability to taste PTC.

According to this question, if two heterozygous tasters (Tt) cross to have a large family i.e. Tt × Tt, the following gametes will be produced by each parent;

Tt = T and t

Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

TT, Tt, Tt - Tasters (3/4 or 75%)

tt - Non-taster (1/4 or 25%)

Note that based on the question asked, there is a 75% probability that their first child will be a taster because there is equal segregation of alleles into gametes.
