Answer:
protein is the right one
Explanation:
The correct option is B. The protein is a organic molecule is indicated by the color change of the solution.
What is Biuret test?The egg becomes violet when two drops of copper sulphate and ten drops of caustic soda or NaOH are put to it. This suggests that proteins are present.
This is the Biuret test, and the basic idea is as follows: Caustic soda or NaOH, which are both alkaline media, cause the Cu²⁺ ions are converted to Cu.
Copper sulphate (CuSO₄), sodium hydroxide (NaOH), and sodium-potassium tartrate are the ingredients in the biuret reagent (also known as Rochelle salt). This reagent does not include biuret (H₂N-CO-)2NH, despite its name. It plays a crucial role in the Biuret protein assay.
Therefore, The correct option is B. The protein is a organic molecule is indicated by the color change of the solution.

Read the statements regarding how cells obtain and use energy. Does each statement describe plant cells, animal cells, or both? Drag each statement to the correct place in the chart.
Answer:
Only animal cells: must consume food in the form of other organisms, produce carbon dioxide as waste
Only plant cells: convert the suns energy into sugars, use water and carbon dioxide to produce energy
Both: require oxygen to get energy from food, require mitochondria to produce usable energy

All carbohydrates are made from smaller building blocks known as Blank Their main function is Blank. The elements found in carbohydrates include Blank
Answer:
All carbohydrates are made from smaller building blocks known as monosaccharides. Their main function is energy storage. The elements found in carbohydrates include Carbon, Hydrogen, and Oxygen
Explanation:
Carbohydrates are a fundamental organic compound that is essential to life. Their building blocks are known as monosaccharides, these are also known as simple sugars such as glucose. They all follow the same multiple of the unit C6H2O (1 C : 2 H : 1 O). We need to carbohydrates to store energy so that when we consume them we can perform cellular respiration, a highly precise process where we can break down glucose to form ATP for our body.
which best represents an example of carbon fixation?
The option that best represents an example of carbon fixation would be the incorporation of CO2 into organic molecules.
Carbon fixation refers to the process of converting atmospheric carbon, mostly in the form of carbon dioxide, to organic molecules in the form of carbohydrates, usually in living organisms.
In living organisms carbon is fixed either via photosynthesis or chemosynthesis.
During the photosynthetic process, inorganic carbon in the form of carbon dioxide combines with water and is converted into carbohydrates in the presence of radiant energy. The process usually happens in green plants.
During chemosynthesis, carbon dioxide reacts with H2S instead of water to arrive at carbohydrates. The process usually happens in chemosynthetic bacteria.
More on carbon fixation can be found here: https://brainly.com/question/7142342
The process of photosynthesis is the best example of carbon fixation.
In the process of photosynthesis, energy from sunlight drives the carbon fixation pathway. photosynthesis process is used by the primary producers such as plants, algae, and cyanobacteria. They contain green pigment named chlorophyll that used the Calvin cycle to fix carbon.
The carbon atom present in the atmosphere in the form of carbondioxide gas fixes by the producers in the form of glucose which have 6 carbon atoms so we can conclude that photosynthesis is the best example of carbon fixation.

what organ in the body regulates erythrocyte production?
Answer:
The hormone erythropoietin regulates enthrocyte production, which is produced in the kidneys.
Explanation:
Bone marrow is the body organ responsible for controlling erythrocyte (red blood cell) synthesis.
The process of erythropoiesis, which occurs largely in the bone marrow, produces erythrocytes. Hematopoietic stem cells, which can differentiate and develop into several types of blood cells, including erythrocytes, are found in the bone marrow.
The hormone erythropoietin (EPO), which is produced and secreted by the kidneys in response to low oxygen levels in the body, regulates the formation and release of erythrocytes. EPO stimulates the formation of erythrocytes in the bone marrow, maintaining an adequate supply of oxygen-carrying red blood cells in the bloodstream.

Hemophilia is a disorder in which there is a failure in one of the steps of clot formation.What might be some advantages and disadvantages of this disorder?
People who have severe hemophilia may benefit from regular injections of clotting factors as a preventive treatment. This may lower the risk of severe bleeding. Severe hemophilia affects the blood's clotting ability so much that people who have it may start bleeding for no apparent reason.
Hemophilia can result in: Bleeding within joints that can lead to chronic joint disease and pain. Bleeding in the head and sometimes in the brain which can cause long term problems, such as seizures and paralysis. Death can occur if the bleeding cannot be stopped or if it occurs in a vital organ such as the brain. Complications of hemophilia can include: Deep internal bleeding. Bleeding that occurs in deep muscle can cause the limbs to swell. The swelling can press on nerves and lead to numbness or pain.
