Answer:
Hydrogen gas has the highest calorific value of 150 KJ/g among all the fuels. So, hydrogen gas is considered to be an extremely good fuel.
Explanation:
Answer:
Unlike the queen bee, which has 32 chromosomes, drones have half the chromosomal charge (n= 16), so they are considered haploid.
Explanation:
The system of determination of the sex in the bees —like in other insects— is called haplodiploidy, and consists of which the females of the species possess complete charge of chromosomes, whereas the males only possess half. This is what happens with the queen bee with 32 chromosomes, while drones only have 16 chromosomes, so they are considered haploid.
Additionally, as a characteristic of haplodiploidy, males only proceed from female gametes, so they can only contribute gametes to produce females of the species.
The other options are not correct because:
- <em>Drones, with half of the chromosomal charge, </em><u><em>cannot be diploid</em></u><em>.
</em>
- <u><em>Monosomy and trisomy</em></u><em> are defects in the distribution of chromosomes during meiosis, which imply one chromosome less or one chromosome more in the normal chromosome charge respectively.</em>

Answer:
plasmolysis
Explanation:
plasmolysis is the shrinkage of the vacuole and pulling away of cytoplasmic linings from the cell wall when water leaves the cell.
Answer: Mitochondrial proteins are generally involved in mitochondrial functioning and the functions they carry out
Explanation:
Mitochondrial proteins are synthesized in the cortisol by the ribosomes and are delivered as precursors to the mitochondria before folding and remodeling processes takes place which are carried out by the chaperones.
Mitochondrial proteins which resides in the matrix and the cristae are involved generally in mitochondria functions such as carrying the reactions in the electron transport chain among others.
The proteins which are already active at the cortisol may remain there, which is why it is advantageous for the proteins to be in their precursor state so that they will be properly targeted to the matrix to be synthesized and to function.
