*In addition to the bacterial, virus, fungus, some microorganisms live under the sea*what are they?
A microorganism (or microbe) is any microscopic living organism or virus, that is too small to see with the unaided human eye without magnification. Microorganisms are very diverse. They can be single-celled or multicellular and include bacteria, archaea, viruses and most protozoa, as well as some fungi, algae, and animals, such as rotifers and copepods. Many macroscopic animals and plants have microscopic juvenile stages. Some microbiologists also classify biologically active entities such as viruses and viroids as microorganisms, but others consider these as non-living.

What is the shape of a skin cell that helps it create a protective layer? A. The cell is tapered at each end and allows them to fit together easily. B. The cell is long and rectangular so that they stack and make straight pathways into the body C. The cells are short and flat which make they easy to layer and overlap. D. The cells have no defined shape so that they move easily with the body.
The cells are short and flat which make they easy to layer and overlap and create a protective layer. thus option C is correct.
How skin cell get extracted?Primary skin cells of human or animal origin are extracted via the enzymatic and mechanical dissociation of dermal or epidermal tissue.
The cell of skin is short and flat.The shape of these cells enables a new barrier of three-way tight junction contacts to form between them and the neighboring cells in the stratum granulosum. After this barrier has formed, the upper cell leaves the stratum granulosum. thus option C is correct.

Melinda and Bart are sitting beside each other in the third car of a roller coaster.
From whose reference point are Melinda and Bart moving away from the observer?
A. a person sitting in the first car of the roller coaster
B. a person standing on the ground behind the roller coaster
C. a person sitting in the last car of the roller coaster
D. a person standing on the ground in front of the roller coaster
Answer:
The answer option that you are searching for today is the option "B."
From the reference point of a person standing on the ground in front of the roller coaster, Melinda and Bart are moving away from the observer. Therefore, option (D) is correct.
What is the reference point?A reference point is a fixed location or object used to determine the position, speed, and direction of motion of an object or person in motion. It is used in physics and other sciences to describe the motion of objects.
This is because the roller coaster is moving forward along the track, and the third car, where Melinda and Bart are sitting, is behind the first and second cars. As the roller coaster moves forward, the distance between the third car and the person standing on the ground in front of the roller coaster increases, indicating that Melinda and Bart are moving away from that observer. Therefore, the correct option is D, "a person standing on the ground in front of the roller coaster."

Explain how manganese and iron ores commonly form.
Answer:
The iron ore deposits began forming when the first organisms capable of photosynthesis began releasing oxygen into the waters. This oxygen immediately combined with the abundant dissolved iron to produce hematite or magnetite. ... Steel Mill: Most iron ore is used to make steel.
The metal is obtained by reducing the oxide with sodium, magnesium or aluminium, or by the electrolysis of manganese sulfate. Manganese nodules have been found on the floor of the oceans. These nodules contain about 24% manganese, along with smaller amounts of many other elements.

Explanation:
I dont get the question its just a chart
What protects Earth's surface?
O the atmosphere
o the hydrosphere
O the geosphere
O the biosphere
Earth's surface is protected by the atmosphere that is the first option as It provides a shield from harmful radiation and meteors, regulates the planet's temperature, and provides the air we breathe.
The atmosphere is a thin layer of gases that surrounds the Earth. It's made up primarily of nitrogen (78%) and oxygen (21%), with trace amounts of other gases. The atmosphere protects the Earth's surface by blocking harmful solar radiation, such as ultraviolet rays, from reaching the surface. It also helps to regulate the Earth's temperature by trapping heat from the Sun, which keeps the planet warm enough to support life.
