Answer:
Craters resulted when meteoroids crashed into the surface of the moon.
Explanation:
Craters resulted when meteoroids crashed into the surface of the moon. The correct option is D.
What are carters?On many solid planets and moons, craters are the most common surface features.
Craters cover both Mercury and the Moon. Numerous circular holes cover this area of the Moon. Each of these craters was formed when an asteroid or comet collided with the Moon's surface.
A crater is a bowl-shaped depression or hollowed-out area caused by a meteorite impact, volcanic activity, or an explosion. Impact craters are craters formed by a meteorite colliding with the Earth.
Scientists can study a planet's history using impact craters even when the records are buried beneath the surface.
Buried material is ejected during impact, while outward pressure pushes the rock at the crater's edge upward, forming a rim.
Thus, the correct option is D.

Assume that a 100 base pair DNA ladder contains 45 cytosines. How many guanines are there?
Answer:
45 guanines
Explanation:
In a DNA strand, each nitrogen base only pairs with one other specific base.
Adenine pairs with thymine, and cytosine pairs with guanine.
This means that the amount of adenine is always equal to the amount of thymine, and the amount of cytosine is always equal to the amount of guanine.
So, if the DNA ladder has 45 cytosines, there will be 45 guanines.
Explain why men should not accuse women of not delivering male child for them
Men should not accuse women of not delivering a male child for them because they are not responsible for determining the gender of the child. It all depends on the fusion of chromosomes.
How zygote is formed?The Zygote is formed after the successful fusion of male and female gametes.
Women bear both XX chromosomes, while men bear one X and one Y chromosome. It is a biological phenomenon of fusing these sets of chromosomes and determining the gender of the child.
Therefore, it is well described above.

A skateboarder drops in off the top of one side of the half pipe shown below. She does not push off and starts from rest. She stands straight as she skates down one side and up the other. She expected to get to the top of other side but didn’t make it. The skateboarder recalled the law of conservation of energy from science and didn’t understand why she didn’t make it to the top of the other side.
Which of the following actions would help the skater reach the top of the other side of the half pipe?
Lubricate the wheels in order to reduce frictional force that is causing the skateboard to lose velocity and bend down while skating off the side and bottom of the half pipe.
Hold a weight in order to increase her mass and cause the skateboard to move with a greater velocity down the half pipe.
Sit on the skateboard in order to lower her center of mass and increase the potential energy of the skateboard.
Push off at the bottom of the half pipe in order to replace lost energy and add kinetic energy to the skateboard.
The actions that will help the skater reach the top of the other side of the half pipe is to lubricate the wheels in order to reduce frictional force that is causing the skateboard to lose velocity and bend down while skating off the side and bottom of the half pipe.
The law of conservation of energy from science states that energy can neither be created nor destroyed but can be transformed from one form to another.
The skateboarder couldn't make it to the top of one side of the half pipe because the kinetic energy that was generated was converted to heat energy through friction.
As the heat energy is lost to the surrounding environment, the skateboard loses velocity.
Bending down by the skateboarder will provide additional energy to make up for the lost energy.
Therefore, in order for the skateboarder to reach the top of the other side of the half pipe, she has to lubricate the wheels in order to reduce frictional force that is causing her to lose velocity and bend down while skating off the side and bottom of the half pipe.

to the surface - where on the ramp the ball starts from The students do
change the type of surface the ball rolls on. What is the independent
variable in this experiment? *

type of surface the ball rolls on.What is the independent variable in this experiment
Answer:
The ball
Explanation:
because it is the variable that is altered/used during this scientific experiment. It would not be the ramp or distance because the ramp is what's being tested or measured (dependent variable) and the distance is what stays the same (controlled variable).

por que un globo con aire se agranda al sol y se achica en la heladera
Answer: El globo congelado se contrajo porque la energía cinética promedio de las moléculas de gas en un globo disminuye cuando la temperatura disminuye. Esto hace que las moléculas se muevan más lentamente y tengan colisiones menos frecuentes y más débiles con la pared interior del globo, lo que hace que el globo se encoja un poco.

1. Compare the density of stomata between the two varieties of olive plant A and B
2. Under identical environmental conditions the rate of water uptake in plant A is higher than plant B
Plant A has more stomata than plant B and therefore plant A can take more water, thereby under identical environmental conditions, the rate of water uptake in plant A is higher than in plant B (questions 1 and 2).
What are plant stomata?Plant stomata are structures located on the leaves which serve to absorb water and they also serve to the gas exchange processes during photosynthesis, which is fundamental because one output of this process is oxygen while the input is carbon dioxide.
The amount of plant stomata per unit of area is fundamental to determining the water intake rate that a plant has in certain environmental conditions.
Therefore, with this data, we can see that plant stomata are required to take water and also for gas exchange during photosynthesis, thereby a plant with more stomata will be able to obtain more water.
