write one function of uric acid​

Answers

Antioxidant

Explanation:

Most serum uric acid is freely filtered in kidney glomeruli, and approximately 90% of filtered uric acid is reabsorbed, implying that it has a considerable physiological role [2], [5]. In humans, over half the antioxidant capacity of blood plasma comes from uric acid [5], [6]. Uric acid is a strong reactive oxygen species (ROS) and peroxynitrite scavenger and antioxidant [5], [6], [7], [8]. High levels of uric acid are readily detected in the cytosol of normal human and mammalian cells, especially in the liver [9], vascular endothelial cells, and in human nasal secretions, where it serves as an antioxidant

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.

The marine Biomes consists of coral reefs, oceans and estuaries and marine algaes which provides the most of the oxygen needed in the world. Ocean marine biomes are salty and organisms living in such biomes have to live in extremely salty conditions.

Sunlight does not easily penetrate the Ocean marine Biomes due to the depth therefore the organisms must live without sunlight for most of their lifetime.

Explain how manganese and iron ores commonly form.

Answers

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.

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

Answers

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."

The atmosphere, it is the envelope of gases surrounding the earth or another planet. hope this helps

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.

Describe how a plant takes in carbon dioxide from the air and mineral ions from the soil.

Answers

Answer:

plant takes carbon dioxide in the atmosphere with the help of leave and take mineral ions from soil with the help of roots

Plants take up essential elements from the soil through their roots and from the air (mainly consisting of nitrogen and oxygen) through their leaves. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps. Plants absorb water from the soil through the roots by Osmosis and They get Carbon dioxide from the air through the Stomata present on the leaves which facilitate for gaseous exchange.
