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
Explanation:
Protons of atoms are the atomic particles with a positive charge while electrons bear a negative charge. Protons are found in the nucleus together with neutrons (that have no charge). They are held together by strong nuclear forces that overcome the repulsive forces between the positive charges in the nucleus. The electrons orbit around the nucleus and are kept in orbit by the electromagnetic attraction of the positive nucleus.
Answer:
C. Phenotypes
Explanation:
Taking notes on all the physical characteristics observed about the tortoises and then observing the finches, I have observed the phenotypes.
Phenotypes are the observable characteristics of a species which are the result of genetic expression influenced by the environmental factors.
So, phenotypes will be recorded during the trip while taking notes on all the physical characteristics which can be directly related to genotype and environmental factors.
Hence, the correct option is "C. phenotypes".
Multicellular organisms are organisms that are made up of more than one type of cell and have specialized cells that are grouped together to carry out specialized functions. ... Similar cells are grouped into tissues, groups of tissues make up organs, and organs with a similar function are grouped into an organ system.
Answer:
Homology refers to the similarities between the group of species that share the common ancestor. The homology individuals arise from a common ancestor. They shows divergent evolution. The basic structure in homology is similar. The organs perform different function. They occur due to the evolutionary process.
Homoplasy refers to the shared characters of the group of species that do not share the common ancestor. The homoplasy do not involve the common ancestor. They shows convergent evolution. The basic structure in homoplasy is different. The organs perform the similar function. They occur due to the adaptation in different habitats.
