Answer:
Nucleic acids are not essential for nutrition
Explanation:
Nucleic acids are a group of biomolecules that functions in the storage and transmission of genetic material within living organisms. DNA is one of the nucleic acids found in nature.
DNA is a storage molecule i.e stores genetic information. It does not store energy, hence, it doesn't serve the purpose of providing nutrient in a cell. Therefore, DNA will not be included on the nutrition labels for strawberries because they are not essential biomolecules for nutrition.
Answer:
The sentences can be completed as follows:
The enzyme lactase breaks down the sugar lactose.
If the body doesn’t produce much of this enzyme, people have what’s called lactose intolerance.
During the chemical reaction the enzyme doesn’t get used up, but gets reused.
Enzymes are substances that speed up chemical reactions which are also known as catalysts.
Explanation:
Enzymes can be described as molecules which act as biological catalysts i.e they are involved in speeding up a chemical reaction. The enzymes do not get used up in a chemical reaction and hence, they can be reused.
Lactase is an enzyme which helps in breaking down the sugar lactose which is commonly found in the milk. If enough lactase is not produced by a person's body, then he/she becomes unable to digest the sugar lactose. Such a condition is known as lactose intolerance.
Organic farming methods enable farmers and gardeners to prepare soil in such a way that nitrogen is added naturally through nitrogen-fixing bacteria rather than nitrogen having to be added through a synthetic fertilizer. This method of growing crops saves farmers money and alleviates the problems associated with fertilizer runoff
Farmers and gardeners should use other methods to provide crops with the nitrogen they need.
Algal blooms are due to the accumulation of algae, generally Cynabobacteria and Dinoflagellates, that grow due to excess nutrients in water.
If good algae grow, they do not accumulate in the waterbodies.
Diatom Algae are good algae.
Therefore if Diatoms are grown instead of Cyanobacteria and Dinoflagellates, there would be no accumulation and no problem of algal blooms.
Answer:
DNA and genetic code
Explanation:
Comparing DNA can show how species are related.
