Answer:

A protoplanetary disk is  round rotating object which is made of dense gas. This surrounds the newly formed star, Herbig star and T tauri star.

It is also considered as a accreation because the remnants like gases and other materials fall from them on to the star.The extremely illuminating protoplanetary disk are known as the proplyds.

Whereas the nebula can be defined as the densely packed hydrogen and other gases that collapse under the force of gravity. The Nebula starts becoming smaller and smaller because the particles of gases collapse and get closer to each other.

Upon force of gravity their friction and heat increases which slowly collapse the star.

Oksanka [162]
The answer is vacuole and centriole lysosome. An animal cell contains all 3.

An animal cell does not have chloroplasts and a cell wall(a plant has those things). A plant uses chloroplasts (that contains chlorophyll) for photosynthesis. A cell wall is to give the plant a rigid shape(that's why most plant cells look rectangular while animal cells look circular).
Hope this helps :)

Answer:

The correct answer is - C. protein - Millons' test - red precipitate is formed.

Explanation:

The iodine test is the test that is used for the identification or presence of the starch in a food sample, in this test if starch present in the food then the solution of iodine and KI will turn to deep blue color. Therefore the given result is incorrect

The benedict test for confirming if glucose present in the sample, it is a mixture of sodium carbonate, sodium citrate, and copper(II) sulfate pentahydrate which starts as aqua blue in color but after adding sample and gradually heating it turns from yellow to orange as per the concentration of the glucose. Thus, it is incorrect.

The emulsion test also produces the milky precipitate or emulsion in presence of fat or lipid in the sample. so, it is incorrect.

Millon's test for protein is the test that results in the red solution or red precipitate in the presence of the protein in the sample.

Its definitely not A or D because there are 26 weeks in 6 months.

generally, a weight loss of 1-2 lbs per week is reasonable and safe. 

I would say B because it is unrealistic that someone would always lose 2lbs a week
