Explanation:

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.

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.

The need for  affiliation might explain why we "friend" people on social  media websites, join clubs or hobby groups, and spend time with others when we  might otherwise feel like being by ourselves.

Psychologically, when we associate ourselves with other people on social media websites, events, bars or we go on clubbing, we desire the need of affiliation at the moment.

Affiliation is a process whereby individuals connect with one another which is rooted in deepened closeness and likeness to that other person with an intention that is not focused on taking advantage of the other person.

Advantages of affiliation to other people include:

Answer:

1CH4 + 2O2 --> 1CO2 + 2H20

Explanation:

You have to balance the equation. That means you have the same number of atoms of each element on both sides of the equation. For example, if you have 4 C (carbon) on the left side before the arrow, you also have to have 4 C on the right side.

Having 1 CH4 on the left gives you 1 C and 4 H.  On the right side, there is also 1 C in the CO2 and since there are only 2 Hs in H2) you need 2 H20 to balance the 4 Hs. You do the same thing for each letter. So since you needed 2 H2O to balance the Hs, that gives you 2 O2s , plus 2 more Os on the side of the equation from the 1 CO2, for a total of 4 Os on the right side. Therefore, yu need 4 Os on the left. there are 2 in O2, so then you need 2 of O2.

You just have to keep adding them up until there is an equal number of each letter on each side.

Explanation:

The term "You are what you eat" was coined due to the effects of the content of the food we ingest on the rest of our organism.

Food comes in an endless number of options, each of which contains numerous molecular compounds of varying kinds. Every molecular compound that we ingest through the food that we eat can have distinct effects on the body, some of these compounds include:

Macromolecules are a class of molecules that encompass many others. Proteins and lipids are just some of the examples mentioned that fall within the class of macromolecules. Some macromolecules can be good for the body, such as proteins, whilst others can cause some negative effects as is the case with lipids.

Lipids are vital for the proper functioning of the body. Lipids provide a source of reserve energy and can regulate hormones, among other important functions. However, lipids can also be harmful to your health. Lipids provide reserve energy by being stored as fat. Excessive consumption of lipids can cause numerous health problems.

Carbohydrates are at the same level as lipids in terms of their effect on the body. Carbohydrates are sugars, which are necessary to include in a healthy diet, however, excessive consumption of carbohydrates can cause health issues ranging from diabetes to pancreatic failure.

Proteins are amongst the most essential macromolecules for the human body. They provide a variety of functions which include:

among many others. This, along with nucleic acids are a prime example of "you are what you eat" in that those who consume more of these (coupled of course with proper exercise) tend to be healthier individuals.

Some examples of microorganisms that utilize the Calvin cycle include cyanobacteria, purple bacteria and nitrifying bacteria.

Specifically, the Calvin cycle involves reducing carbon dioxide to sugar trisoe phosphate, most commonly known as glceraldehyde 3-phosphate (GAP).

The Calvin cycle involves reducing carbon dioxide to sugar trisoe phosphate, most commonly known as glceraldehyde 3-phosphate in bacteria.

The Calvin cycle, light-independent reactions, bio synthetic phase, dark reactions, or photosynthetic carbon reduction cycle of photosynthesis is a series of chemical reactions that convert carbon dioxide and hydrogen-carrier compounds into glucose.

The Calvin cycle has four main steps: carbon fixation, reduction phase, carbohydrate formation, and regeneration phase. Energy to fuel chemical reactions in this sugar-generating process is provided by ATP and NADPH.

The Calvin cycle is a process that plants and algae use to turn carbon dioxide from the air into sugar, the food autotrophs need to grow. Every living thing on Earth depends on the Calvin cycle.
