Answer:
Scientists show evidence that nitrogen acquired during Earth's formation came from both the inner and outer regions of the protoplanetary disk. Nitrogen is a volatile element that, like carbon, hydrogen and oxygen. Nitrogen makes up 78 per cent of the air we breathe, and it's thought that most of it was initially trapped in the chunks of primordial rubble that formed the Earth. When they smashed together, they coalesced and their nitrogen content has been seeping out along the molten cracks in the planet's crust ever since.

The student plans this cutting into a pot with soil, and he grows along side the original point where it came from. Which explanations best match with the description an image shown here in the scenario? Select all that apply.
Answer:
If its on usa test prep it would be
A) The new root growth is a result of meiosis
B) the new plant formed from as reproduction
D) The new plant is genetically identical to the original plant.
The new plant grows vegetatively from the cutting and will look exactly like the original plant.
Vegetative propagationCutting is a form of vegetative propagation attribute of some organisms.
Cutting a tissue off a plant and the tissue developing its own root to become a new plant happens by mitosis.
Mitotic division of the cut tissues leads to the formation of roots and the eventual growth to a new plant.
Mitotic growth means that the new plant will be genetically and physically identical to the parent plant, provided they grow under the same conditions.

A student named Janine says that the measure of side b is 64 ft. Please state whether this is correct or incorrect. If this is incorrect, state the length of b. Explain your answer in complete sentences. Use vocabulary such as Pythagorean Theorem, side, hypotenuse, square root etc.
The measure of side b as 64 ft is incorrect. The accurate measure would be 8 ft.
According to the Pythagorean theorem, the square of the hypotenuse of a right-angle triangle is the sum of squares of the opposite and the adjacent sides. Mathematically:
[tex]hypotenuse^2 = opposite^2 + adjacent^2[/tex]
In this case, the hypotenuse = 10 ft, the opposite = 6 ft and the adjacent = b
Hence,
b^2 = 10^2 - 6^2
= 100 - 36
= 64
b = √64
= 8 ft
Thus, the side b is 8 ft and not 64 ft.

Plants lose __ % water to transpiration resulting in 10% increase in atmospheric water vapor which increases relative humidity and chance of precipitation.
A: 90
B: 10
C: 100
D: 45
Answer: A
Explanation: Transpiration is the loss of water from the plant through evaporation at the leaf surface. It is the main driver of water movement in the xylem. Transpiration is caused by the evaporation of water at the leaf–atmosphere interface. Up to 90 percent of the water taken up by roots may be lost through transpiration as only a small amount of that water is used for growth and metabolism.

Say that you look at the nuclei of 100 skin cells taken from the same person. About how many of these skin cells would you expect to be in interphase
Answer:
45 cells would be in the interphase
In the nuclei of 100 skin cells. The number of skin cells would be in interphase is 45.
What are cells?Cells are the key unit of living organisms. The cell divides into many cells through the process of cell division.
Prokaryotic cells are the primitive type of cells that are present only in unicellular organisms, and they do not undergo cell division. These cells do not have true cell organelles and a nucleus, in that DNA is present in coil form in the cytoplasm. They contain ribosomes the organisms are bacteria that contain prokaryotic cells.
Eukaryotic cells are higher cells that contain cell organelles they have to perform various complex functions of large organisms. They have a nucleus which contains DNA or genetic material, it does not have flagella.
Therefore, the number of skin cells in the interphase is 45 cells.

Brainliest pls if correct!Osteoporosis is more prevalent among women than men because women generally
have more bones in their bodies than men have.
take in more calcium than men take in.
have lower bone mass than men have.
exercise more than men do
Answer:
Have lower bone mass than men have
Explanation:
Osteoporosis is a bone thinning disease that is more prevalent among women than men and typically occurs after 50. The reason women are more likely to get the disease than men is because after 50 many women have gone through or are going through menopause. Menopause causes the ovaries to produce less estrogen which is what had previously been promoting bone density.
The other answers are incorrect because...
A: have more bones in their bodies than men have: for the most part everyone has the same amount of bone in there body (although there are diseases that cause a persons bones to fuse together making them have fewer bones than the average person)
B: take in more calcium then men take in: more calcium would actually cause someone to be less likely to get osteoporosis because it strengthens the bones.
C: exercise more than men do: Osteoporosis is more common in malnourished women and women who do not get regular physical activity to strengthens there bones. So getting more exercise would actually lessen the chance of getting osteoporosis.
