Which of the following statements is true? which of the following statements is true? carbohydrates are water soluble and responsible for short term energy storage. monosaccharides are the building blocks of peptides. polysaccharides are the building blocks of amino acids. fatty acids are responsible for dna replication. nucleotides are the building blocks of saccharides.

Carbohydrates are water soluble and responsible for short term energy storage.

Explanation:

Carbohydrates also known as saccharides are major class of biomolecules composed of C, H and O.

Their empirical formula is

m and n can be different.

Simplest form of glucose having only one monomer is called monosaccharides.

Two monosaccarides bonded together to form disaccharides.

Similarly, if more than two monosaccharides are bonded, the polysaccharides are formed.

Carbohydrates are soluble in water because of the presence of hydroxyl group.

Carbohydrates are energy provider and also used in the body as short term energy storage.

Fatty acids are used as long term energy storage.

So, among given the statement,

'Carbohydrates are water soluble and responsible for short term energy storage' is correct

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
