Answer:
When a water and limestone slurry is used as a scrubber, the impact of modifying the slurry by increasing the amount of limestone has as a consequence that the amount of sulfur dioxide released will decrease.
Explanation:
One of the consequences of the use of coal as fuel is the emission of toxic gases, one of which is sulfur dioxide (SO₂), a colorless and toxic gas that can affect the health of humans and animals. That is why SO₂ scrubbers are necessary for the removal of this gas.
One of the most commonly used SO₂ scrubbers is the suspension of water and limestone, since the calcium (Ca) contained in the limestone reacts with the SO₂ to form calcium sulfide (CaS), which precipitates as a solid, decreasing the emission of SO₂ to the environment.
It is for this reason that, by <u>increasing the amount of limestone in the scrubber slurry, more SO₂ will react, and the amount released from this gas will decrease.</u>

Answer:
B.chickens are more closely related to ducks than they are to humans.
Explanation:
Amino acids are coded for by codons.
Codons are sequence of nucleotide bases from mRNA.
mRNA are synthesized using DNA templates.
Therefore, the more similar the amino acid sequence of two organisms, the more genetically related the organisms are.
<em>Chickens and ducks had amino acid sequence of 3 while chickens and humans had 13. It thus means that chickens and ducks are more related as compared to chickens and humans.</em>
The correct option is B.
1. Genetics and environment influence the trait as it depends upon the adaptation made according to availability and environment.
2. Traits are passed onto either parents after fertilization when 2 genes from either parent is received.
3. Dominant trait is responsible for the phenotype of the individual.
4. The expression of gene is seen by the phenotype expressed depending upon the environmental factors.
Explanation:
The food preferences are based on the traits adapted over the time for digestion and method of eating due to natural selection. The occurrence of beneficial trait for digestion become common in the population as these traits are transferred for better survival and evolution.
The traits in an organism is passed on from parents. During fertilization one allele from each parent is passed onto the progeny. 2 alleles together are called gene. In the process of meiosis only one chromosome is present in germ cell hence no homologous chromosome thus only one allele for the trait is present in each parent.
The alleles of dominant trait mask the effect of recessive alleles during phenotype expression. According to law of complete Dominance the dominant trait gets expressed and recessive trait do not get expressed.
The temperature, external environment, chemicals, light factor, diet etc influences the expression of genes in certain organisms. The effect of these can be seen on the phenotype of the organism.
