The best answer is D.
Nothing would happen because the disease is genetic. It is inherited and not acquired and its cause has absolutely nothing to do with malaria. The only thing that malaria does is that it can cause a dangerous medical condition called sickling crisis in a person with the sickle cell disease which does not occur in people who do not have sickle cell disease even if they get infected with malaria.
The cause of sickle cell disease is a mutation in the Beta chain of the protein molecule called hemoglobin. The mutation causes the 6th amino acid called thymine in the beta chain to be substituted with another amino acid called valine. This change of a single amino acid causes the hemoglobin molecule to behave abnormally resulting in sicke cell disease.
Explanation:
Similar rock types can be used as an evidence for continental drift because rocks forms under different geologic conditions.
Most natural depression on the earth surface are filled with thick sedimentary sequences that have been subjected to lithification.
In some terrain, magmatic activities are rife with prevailing tectonic settings controlling how they cool and solidify.
Also, some terrains have experience prolong metamorphic change and this dives spurious metamorphic transformation of minerals.
- A terrain will have a rock type that typifies it.
- If the two terrains become separated, it is possible to correlates the rock sequences in them.
- For sedimentary rocks, a geologic column and stratigraphy can be useful on correlating them.
- In metamorphic rocks. different facies have typical index minerals in them that can be used to match them.
- Dating some minerals in igneous rocks and even establishing sequences have proven useful in explaining continental drift between terrains

Answer:
Anaerobes carry on cellular respiration in the absence of oxygen, whereas aerobes carry on cellular respiration in the presence of oxygen.
Explanation:
Many of the cell processes needed need some energy to occur. Cellular respiration is the process by which cells degrade organic compounds and turn them into energy. Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.
<u>Aerobic Respiration</u>
- Occurs in the presence of free oxygen.
- Series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules.
- Respiration occurs in the mitochondria.
- Takes place in two steps or stages: Krebs cycle and electron transporter chain.
- Glycolysis and Krebs cycle produce electrons, which then travel along the electron transporter chain while releasing energy, and ATP is produced.
<u>Anaerobic Respiration </u>
- Occurs in the absence of free oxygen
- Series of reactions by which using pyruvate (product of glycolysis) 2 ATP molecules van be produced.
- There are two ways in which anaerobic respiration can be produced: lactic fermentation and alcoholic fermentation.
- Lactic fermentation produces lactic acid and 2 ATP
- Alcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂
- The whole anaerobic process occurs outside the mitochondria.
