a student observed a food sample that’s left a greasy spot on paper and also gave a positive test for starch. which two organic compounds are present in the food sample ?

Answers

Answer 1

Answer:

The correct answer is - fats and carbohydrates are two organic compounds that are present in the sample.

Explanation:

The greasy spot present on paper shows that there are fats present in the food sample that can be butter, ghee, or oil. Fats are the organic compound that provides energy to the organism that eats fat, however, more than a limit fat is harmful to any person.

The starch test suggests that food samples have starch present in the sample, starch is nothing but a polymeric carbohydrate. Carbohydrate is a basic organic compound that provides energy to the body or different organism.

Thus, the correct answer is - fats and carbohydrates.

The hot spring is formed by the erosion of limestone by groundwater and the geyser is formed by the heating of groundwater.

Answers

Answer:

Both are formed when the groundwater gets heated

Explanation:

This is correctamundo

"why?"- you ask

well because when groundwater gets all hot and worked up we get a result in the form of geysers and hotsprings!

Answer:

B. Both are formed when the groundwater gets heated.

Explanation:

Hot springs and geysers are very similar when it comes to how they are formed. The obvious difference is that geysers force up jets of water, whilst hot springs flow water out on their own. They are both formed when the groundwater gets heated from molten rock(magma).

What do the results of the agar blocks indicate about the relationship between cell size and time for materials to reach the center of the cell?




Include an explanation of how the surface area-to-volume ratio, diffusion rate, and time for substances to reach the center are related. Support your explanation with data.


PLZ HELP!!! 50 points!!!

Answers

There is inverse relationship between cell size and time to reach the center.

Cell size has a inverse relationship with the time that the materials needed to reach the center of the cell because if the cell size increases more time is required for a material to reach to the center of the cell due to more distance between the center and boundary of the cell. The surface area-to-volume ratio, diffusion rate, and time for substances to reach the center are related to each other.

If the surface area to volume ratio is higher than more materials can diffuse across the membrane of the cell but more time is required to reach the center because increase in cell size leads to more distance between center and boundary of the cell so we can conclude that there is inverse relationship between cell size and time to reach the center.

What are the conditions favouring AIR-BORNE disease?

Answers

Answer: cold, highly populated areas

Explanation: flu is a great example of an airborne disease. flu is spread mainly at parties, stores, and big cities. Diseases like these like cold air, as warmer air kills it. This is why you should wash your hands with warm water.

hope this helps! Please let me know<3

Answer:

Many common infections can spread by airborne transmission at least in some cases, including but not limited to: CO.VID-19; measles morbillivirus, chickenpox virus; Mycobacterium tuberculosis, influenza virus, enterovirus, norovirus, and less commonly coronavirus, adenovirus, and possibly respiratory syncytial virus.

Air-borne diseases are favoured in various ways like if the pollution rate is high then the spreading of air-borne diseases will be high.

The air-borne disease can also be spread in case if a sick person sneezes or coughs the microbes that cause the disease will be spread in the air and could be inhaled by healthy people which will make them sick.

Many processes occur in the digestive system .which process is best classified as a physical change

Answers

Answer:

This question lacks options, the options are:

A) Saliva converting the starch molecules in crackers into simple sugars

B) Digestive enzymes breaking down proteins into smaller fragments

C) bacteria converting lactose into simple sugars in the intestines

D) teeth grinding an almond into smaller pieces in the mouth

The answer is D

Explanation:

A physical change is a change that occurs to a substance without altering its chemical composition. A physical change involved a change in the substance's shape, texture, color, state etc. but not the chemical content of such substances.

In this question involving the processes that occur in digestion, a typical example of physical change is "teeth grinding an almond into smaller pieces in the mouth" because the teeth only changes the shape and texture of the almond. It does not affect the chemical composition of the almond fruit. This is also called mechanical digestion.

Note that, other options involving digestive enzymes breakdown are chemical changes because the enzymes breakdown the chemical components of each substance.

Answer: D

each of my nucleotides includes a phosphate sugar and base am i dna or rna

Answers

Nucleotides are defined as the building blocks of DNA and RNA. These are the genetic material found in every living cell. The nucleotides are made up of sugar, a phosphate group, and nitrogenous bases.

The molecules like DNA and RNA have some of the building blocks same. The pentose sugar and nitrogenous bases. The molecule when composed of sugar molecules and nitrogenous bases are termed as a nucleoside.

The addition of the phosphate group to a nucleoside forms the nucleotide.

RNA is composed of nitrogenous bases (adenine, cytosine, uracil, and guanaine), pentose sugar (ribose), and a phosphate group.

DNA is composed of nitrogenous bases (adenine, cytosine, thymine, and guanaine), pentose sugar (deoxyribose), and a phosphate group.

Thus, DNA and RNA are nucleosides consisting of nitrogenous bases (purines and pyrimidines) and sugar groups.

Therefore, the correct answer is the molecule can be DNA or RNA.
