Why will the footprints left by Apollo astronauts last for centuries?

2 answers:

7 0

Due, to know life on the moon there would be nothing to mess with the footprint, but the main reason why these footprints are going to last centuries is because "there is no weather." Since how there is no weather on the moon which means no wind there is no factors that could affect the footprint.

Hope this helps!

Explanation:

The footprints on the moon's surface left by the Apollo astronauts last for long long time, for centuries, because there is no atmosphere in the moon's surface. As there is no atmosphere in the moon's surface, there is no water and no wind on the moon. So there is no chance of any erosion by wind or water. All the water is present in the frozen form on the moon. Also there is no any volcanic eruption nor any kind of natural forces that will destroy the footprints of the astronaut.

Why are mitochondria bigger in animal cells

Greeley [361]

When you think about the main purpose of mitochondira (to produce energy; an easy idea how to remember the function of mitochondria in our bodies is to imagine them as energy factories or power plants) it becomes easy to understand why.

Animals (including us) move a lot more compared to plants. For movement you need energy and energy needs to be produced in our bodies in order for us to be able to move. Therefore, we have mitochondria that are bigger. Not only that, animal cells usually also have more mitochondria. All of this is probably done to keep up with the increased energy demands that moving organisms have.

Can someone please help

Answer:

P = 0.79.

Explanation:

To solve this, we need to understand the Hardy-Weinburg equation and what each variable is. P is usually used for the dominant trait classification (in this case, it would be long legs) and Q is usually used for the recessive trait classification (in this case, it would be short legs).

Therefore, we know that the values have to add up to 1 and that Q is recessive and P is dominant. So, if we begin applications, we can learn that to equal 1, we must use numbers less than 1 to accomplish this.

If 21 of a 100-person population have short legs, then ideally, 79 people would have long legs (the dominant trait). So, we know that 0.21 as q and 0.79 as p would equal 1 if you just added p and q together. Therefore, we can know that q is 0.21 and p is 0.79.

To prove this, we can insert these values into the equation:

$0.79^{2} + 2(0.79*0.21) + 0.21^{2} =1$

$0.6241 + 0.3318 + 0.0441 =1$

$1=1$
