Meiosis<span> and </span>mitosis<span> are both preceded by one round of DNA replication; however, </span>meiosis<span> includes two nuclear divisions. The four daughter cells resulting from </span>meiosis<span>are haploid and genetically distinct. The daughter cells resulting from </span>mitosis<span> are diploid and identical to the parent cell.</span>
Answer:
The chemical reaction that represents the process of aerobic cell respiration is oxygen + glucose → water + carbon dioxide + energy
Explanation:
Cell respiration occurs in the mitochondria of eukaryotic cells and consists of a series of chemical reactions in which energy in the form of ATP molecules is obtained from a glucose molecule in the presence of oxygen.
<u>Glucose is the main energetic substrate</u> to be able to synthesize energy in the form of ATP, through oxidative phosphorylation. At the end of the process ATP is obtained as products, and as waste compounds water and carbon dioxide, which can be schematized in the following chemical reaction:
<em> C₆H₁₂O₆ + 6O₂ → 6H₂O + 6CO₂ + ATP ↑</em>
<em> Glucose + Oxygen → Water + Carbon dioxide + Energy ↑</em>
This reaction summarizes what happens in aerobic cellular breathing, which is necessary to synthesize energy for cellular functions.
The other reactions:
- <em>oxygen + water </em><em>→</em><em> glucose + lactose
</em>
- <em>glucose + lactose </em><em>→</em><em> oxygen + water
</em>
- <em>water + carbon dioxide + energy </em><em>→</em><em> oxygen + glucose</em>

Answer:
Explanation:
Since it is a recessive gene, tumor suppressor genes required the inactivation of both alleles, this is usually accomplished by the mutation of one allele and a targeted homozygous deletion of the second allele. This leads to an effective inactivation of the suppressor genes with the mutations acting a a dominant negatives. This way, patients are put at a higher risk of developing cancer
An example of an dramatic environmental event can be deforestation, or it can be animals losing their homes.
