Answer:
Urey and miller cooked a "primordial soup" with Hadean gases, water and electricity to make glucose, acetic acid, amino acids and lipids.
Explanation:
In the Miller-Urey experiment, the aim was to reproduce the conditions of the earth before the existence of life, with the objective of demonstrating the formation of organic matter from inorganic molecules.
The scientists took water and gases present in the Hadean eon —previous to the existence of life— such as methane, carbon dioxide, hydrogen, nitrogen and even ammonia, the primordial soup. This mixture was subjected to electrical discharges, inside closed containers.
The results were some organic molecules, including glucose, acetic acid, amino acids and fatty acids. In these results the presence of macromolecules, such as proteins or nucleic acids, is not appreciated, however it was a significant contribution to the knowledge of the origin of life on earth.

Answer:
Marshes are area of shallow water, while bogs are deeper areas.
Explanation:
Marshes are around a couple inches to 3 feet while bogs can get up to 6-7 yards deep
The statement that explains Marshes is an area of shallow water, while bogs are deeper areas. The correct option is D.
What are marshes and bogs?
Marshes and swamps are wet areas where water stands for a long time. The areas become so wet and not good for walking, because the soil will drag you down, and you can drown in wet soil. March contains rich soil that give nutrient to the plants and trees.
A bog is a place called freshwater wetlands that accumulates water and mainly this place consists of rotten plants and dead decomposing material called peat. They are found in cold places like northern areas. These places are mainly made by basins and glaciers.
Thus, the correct option is D. Marshes are areas of shallow water, while bogs are deeper areas.

What does DNA do in living things?
Answer:
Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. All known cellular life and some viruses contain DNA. ... The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code.
Explanation:
Answer:
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies

Structures that perform different activities
Explanation:
The different pieces of food represent cell organelles. Cell organelles can be thought of as the cell's mini "organs", each specialized to carry out different functions inside.
For example the nucleus stores our genetic information, ribosomes synthesise proteins, and Golgi apparatus modifies and transports proteins.
This is similar to how our heart, lungs, stomach, and brain perform different roles in the body.

B) The environment inside and outside the patient’s cells will be isotonic and may cause the cells to burst.
C) The environment around the patients cells will be hypotonic and cause the cells to shrink.
D) The environment inside the patient’s cells will be hypertonic and may cause the cells to burst.
The Marianas trench contains Challenger Deep, the deepest point in the ocean floor that we know of today. Challenger Deep is located over 11,000 meters below the ocean surface. What ocean zone would be located just above the floor of Challenger Deep?
Answer:
Above the floor of challenger deep, the ocean zone located would be the Hadal zone .
Explanation:-
THE CHALLENGER DEEP - The deepest location in the ocean is the Challenger Deep, at the southern end of the Mariana Trench (sometimes called the Marianas Trench). It is difficult to measure its depth from the surface, but modern estimates vary from 305 meters (less than 1,000 feet). The Challenger Deep 's great depth is due to the successful steepening of the subducting slab along a region of poor link with the overriding plate tearing away from the northern part of the Mariana Trench in the southern part of the Mariana Trench.
THE HADAL ZONE -: The Hadal zone (named in Greek mythology after the domain of Hades, the underworld),, is the ocean's deepest area lying within oceanic trenches. The hadal zone is located at a depth of about 6,000 to 11,000 meters (20,000 to 36,000 feet) and is present in long but narrow V-shaped topographic depressions.
Hence, the answer is Hadal zone ,which is located just above the floor of Challenger Deep.
Answer:
Hadal zone
Explanation:

is a human is apart of earth's lithosphere true or false
Humans utilize the lithosphere for their habitat, but humans are not a part of it. So the statement is false.
What is lithosphere?The outer, solid layer of the Earth is called the lithosphere. The lithosphere gradually thickens over time as the Earth's convection system's cooling surface layer. It is broken up into quite sturdy plates or parts that move independently of one another. Plate tectonics is the term used to describe these lithospheric processes. The crust and highest layer of the mantle are both included in the lithosphere, which floats atop the weaker asthenosphere. The lithosphere comes in two varieties:
The oceanic crust is connected to the oceanic lithosphere.The Continental crust is connected to the Continental lithosphere.When compared to the continental lithosphere, which is generally 150 km thick and is made up of 50 km of crust and 100 km or more of the topmost mantle, the oceanic lithosphere is typically 50–100 km thick (although is not thicker than the crust under the mid-ocean ridges).
The oceanic lithosphere is denser than the continental lithosphere, whose mantle is connected with crust comprised of felsic rocks, and is mostly composed of the mafic crust and ultramafic mantle.
Therefore, the statement is false.

Red blood cells,carrying dioxide(a waste product of cellular respiration) travel in the blood vessel to the lung; to get rid of carbon dioxide by breathing it out and pick up oxygen deliver the oxygen to all the cells in the body(to participate in cellular respiration and generate energy.
Answer:
True.
Explanation:
Red blood cells or erythrocytes carry oxygen to the cells of the body so that they can have energy and function properly. This is not the only function of red blood cells. Also, they carry dioxide, which is a waste product that needs to be out of our body. Erythrocytes carry the dioxide to the lungs, specifically to the alveoli. In the alveoli due to the inhalation, oxygen enters our body traveling up to the lungs, specifically to the alveoli, where thanks to the thin wall of it as well as the one on the capillaries that are in contact with it, the dioxide enters the lungs to be expelled in the exhalation, and the oxygen is taken by the red blood cells to be used in the cellular respiration and generate energy to keep the vital functions of our body.

Enzymes are composed of what organic molecule? A. Sugars B. DNA C. Fatty acids D. Proteins
Answer: D. Because enzymes are protiens but they are produced of amino acids
Explanation:
Enzymes are composed of proteins, that assist our bodies' chemical reactions to move forward more quickly. For several processes, including digestion and liver function, enzymes are crucial.
What is the function of enzymes?
Health issues might result from having too much or too little of a specific enzyme. Healthcare professionals can also use the enzymes in our blood to look for injuries and illnesses.
Among countless other functions, they are crucial for breathing, food digestion, and the health of the muscles and nerves. Numerous enzymes can be found inside each cell of the human body. Each cell's internal chemical operations can be aided by enzymes.
Digestion enzymes are produced by your pancreas, small intestine, and stomach. The "powerhouse" of digestion's enzymes is actually the pancreas. The most significant digestive enzymes are produced by it.
Therefore, in the human body, enzymes aid in accelerating chemical reactions, hence option D is correct.
