Answer: Decreased ability to carry oxygen.
Explanation:
A mutation can cause a defect in human hemoglobin, resulting in a reduced ability to carry oxygen, which is the first option because not enough oxygen can be bound in such conditions.
What is the significance of hemoglobin gene mutations?The red blood cell contains hemoglobin, which has four polypeptide chains that can be negatively affected if there is a mutation, resulting in less oxygen being carried to the body's cells and organs. Because the red blood cell transports oxygen, mutation reduces the efficiency with which it binds to oxygen, alters the structure of hemoglobin, and causes the sickle-shaped structure red blood cell.
Hence, a mutation can cause a defect in human hemoglobin, resulting in a reduced ability to carry oxygen, which is the first option because not enough oxygen can be bound in such conditions.

If an astronaut weighs 180 pounds on Earth, how much would he weigh on the moon? Why the difference? Explain.
Answer:
The astronaut will weigh 33 Pounds
Explanation:
Why? It's because of the lower gravity on the Moon. Hope this helps! <3
The weight of an astronaut weighing 180 pounds on the Earth will be lesser on Moon. The weight of astronaut on Moon will be 33 pounds.
What is Weight?Weight of an object is the force acting upon the object due to gravity. It is a vector quantity. Weight can be calculated by the formula:
w = m.g
where, w = weight of an object
m = mass pf the object
g = acceleration due to gravity
The Moon has less mass than the Earth because the gravity is less than the Earth's gravity. This is the reason objects weigh less on the Moon than they do on the Earth.
The weight of astronaut on the Moon would only be 33 pounds. This is because objects on the surface of the Moon experience only 16.5% of the gravity that they experience on Earth.
Moon is not only smaller than the Earth but it is only about 60% as dense as Earth. Thus, the gravitational attraction on the Moon is much less than that on Earth, as a result the person weighs less on the Moon.
