Pesticides and fertilizers create water and air contamination and significant health consequences. Chemicals are regulated to reduce water contamination.
What are pesticides?Insecticides, fungicides, and nematicides are all examples of pesticides. It is essential to exercise population control over the unwanted organisms and insects that cause severe damage to the crops. On the other hand, pesticides can never be used in excess, as this would have a negative impact on living things.
Fertilizers are added to the soil in order to improve its fertility and thus the development of plants. In addition, they contain hazardous substances.
Both insecticides and fertilizers are known to include compounds that are potentially harmful. These chemicals almost certainly will lead to the contamination of water and air, in addition to causing health problems for the organisms in the surrounding area.
Contamination of water is a critical problem that has been on everyone's minds for a considerable amount of time. It is possible to lessen the amount of water contamination by lowering the amount of pesticides and fertilizers that are used.

Cystic fibrosis is caused by
a mutation in the affected
individual's DNA.
What type of mutation
causes cystic fibrosis?
A. the addition of several different
codons
B. the loss of one base
C. the loss of a whole amino acid (3
base pairs) this
D. the CAG codon repeating at least 40
times
Cystic fibrosis is caused by a mutation in the affected individual's DNA therefore the type of mutation which causes cystic fibrosis is the loss of a whole amino acid (3 base pairs) and is denoted as option C.
What is Mutation?This is referred to as the change in the DNA sequence of an organism and it often occurs when there is an errors in DNA replication during cell division.
Cystic fibrosis is caused by the loss of a whole amino acid (3 base pairs) from the cystic fibrosis transmembrane conductance regulator gene which was why it was chosen as the correct choice.

You probably know that you need to breathe oxygen to survive. But how does your body use that oxygen? That oxygen helps your body to release _____ energy that is stored in _____ and other carbon based molecules. The energy is _____ to produce _____. This process of using _____ to produce _____ by breaking down _____ molecules is called _____.
That oxygen helps your body to release chemical energy that is stored in sugars and other carbon based molecules. The energy is released to produce ATP. This process of using oxygen to produce ATP by breaking down carbon-based molecules molecules is called cellular respiration.
What is cellular respiration?In Science, cellular respiration can be defined as a series of metabolic chemical reactions that typically occur in both prokaryotic and eukaryotic cells within living organisms, in order to produce energy in the form of adenosine triphosphate (ATP).
Generally speaking, the first step of cellular respiration is a biological and chemical process that is referred to as glycolysis.
In conclusion, we can reasonably infer and logically deduce that all living organisms such as humans, animals, eukaryotes, etc., breathe in oxygen and exhale carbon dioxide in order to survive, which occurs through a process that is referred to as cellular respiration.

Haikus are historically derived from the Japanese Hokku. Hokkus are group poetry that adhere to the 5/7/5 formula. They are intended to comment on the writers' season or surroundings and to generate some form of contrasting visual split by a kireji or "cutting word."

a. fatty acid
b. straight chain sugar
c. nitrogenous base
Answer: a. Fatty Acid
Explanation:
A fatty acid is a carboxylic acid with a long side chain of hydrocarbons. Most fatty acids contain an even number of carbon atoms in the hydrocarbon chain and follow the general molecular formula of CH3(CH2)xCOOH where x is the number of carbon atoms in the hydrocarbon chain.
