Answer: At the inner core of the earth interior, top density continue to increase as thickness decrease.
Explanation:
The Earth is the third plant from the sun and the fifth largest plant. It is the only planet that can harbor life, that have oxygen in the arthmosphere and oceans on the surface. The Earth have three main layer which are the core(the outer and inner core), the mantle and the crust. All the three layers support life existence. The earth inner core is the innermost geologic layer and it is hot and denser. It is a solid ball of 1,220 kilometers. The earth inner core has the highest density (12)than all other layers and it is less thicker than mantle and the crust. Density increase with depth because the pressure increases also.

Answer:
Cotyledons
Explanation:
B) mutation.
C) crossing over.
D) sexual reproduction.
Mitosis enhances genetic continuity rather than variation. Mitosis is responsible for the growth, repair, and maintenance in organisms. Mitosis occurs when simple organisms, like a paramecium, reproduce asexually. All organisms have the same four nitrogen bases within their DNA, but how they are expressed in individuals is a result of their rearrangement as well as changes or mutations during sexual reproduction.
Estuaries, aquatic biome, forms where freshwater streams or rivers merge with the ocean.
Estuaries are a transitionalzone between river environments and ocean environments.
They are impacted by both riverine and marine factors, including flows of freshwater and sediment as well as marine factors like tides, waves, and the inflow of salt water.
In addition to lagoons, river mouths, and tidal creeks, this wide definition encompasses them.
An estuary is a dynamic ecosystem that connects to the open sea and allows seawater to enter in accordance with the tide cycle. The fresh water flowing from rivers and streams dilutes the seawater that enters the estuary.
Therefore, where freshwater rivers meet saltwater seas is where estuary biomes typically occur.

Answer:Estuaries
Explanation:
Estuaries are areas where freshwater streams or rivers merge with the ocean. This mixing of waters with such different salt concentrations creates a very interesting and unique ecosystem
B. Oxygen-rich blood is carried in the aorta from the left ventricle to the body.
C. Oxygen-poor blood is carried through the left pulmonary veins to the left atrium.
D. Oxygen-poor blood is carried through the inferior vena cava to the left atrium.
When an electron jumps up from a low energy level to a higher one, light energy is emitted.
Every orbit around the nucleus of an atom is the same energy level.
After they emit light, electrons are sucked into the nucleus of the atom.
Answer: Option (a) is the correct answer.
Explanation:
Every orbit has a fixed value of energy which means that energy is quantised. When heat is absorbed by the atom then the electrons go from low energy level to high energy level.
Whereas when heat or energy is released by the atom then electrons move from high energy level to low energy level. As a result, this heat is released in the form of visible light.
Thus, we can conclude that the statement when an electron drops down from a high energy level to a lower one, light energy is emitted, is true according to the quantum model of the atom.
