Answer: A. Phenotype
Explanation:
Phenotype: the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
Genotypes produce phenotypes.
<u>Answer</u>: Sperm cell
<u>Explanation</u>:
Amongst all the 4 options given, only the Sperm cell is a gamete (sex cell) while all the three are somatic cells.
- A <em>somatic</em> cell is the one which forms the body of an organism and contains all the genetic information.
- A <em>gamete</em> is the one which is required for the purpose of fertilization. A gamete of male fuses with the gamete of female in a process called fertilization to form a zygote to give rise to a new individual.
- A Sperm cell is basically a <em>male gamete.</em> It contains only half the amount of genetic information as the other half is contributed by the female gamete.
- This difference in the amount of genetic information arises due to the type of cell division that occurs. The somatic cells undergo mitosis whereas a gamete requires meiosis to occur for its formation.
- During mitosis there is a single round of cell division which divides the parent cell into two daughter cells each with the <em>complete genetic information</em>.
- During meiosis the cell undergoes two rounds of cell division such that a total lf 4 cells are produced each <em>with half the amount of genetic material </em>as present in the parent cell.
Since, <em>sperm is a male gamete and is formed by meiosis it contains only half the genetic information as compared to the other cells.</em>
The term "pneumocephalus" refers to the condition in which air is present in the cranial cavity.
What happens in pneumocephalus?
- Increased intracranial pressure causes tension pneumocephalus, a neurosurgical emergency that can cause headaches, seizures, loss of consciousness, and even death.
- Clinically separating the two entities is difficult but essential.
- Tension pneumocephalus following skull base surgery was found to be a rare phenomenon with just eleven cases described, according to a survey of the literature on PubMed/MEDLINE.
- After treatment, the majority of patients experienced full symptom relief.
- Following skull base surgery, tension pneumocephalus is a potential complication that clinicians should be aware of.
- An understanding of imaging characteristics and a high level of suspicion are necessary for accurate diagnosis. Rapid management is essential to avoid potentially disastrous effects.

Answer:
These are things that won't be going away. Natural gasses and fossil fuels will likely run out someday or become much harder to find. When you use these sources of energy, they won't be going away and therefore will be sustainable because we can always continue using them.
Does that make sense?
