Answer: A). A piece of DNA that controls a trait
Explanation: A gene is a functional unit of hereditary. A gene determines the characteristics of an offspring. Genes are said to be functional unit of hereditary because they are transferred from the parents to the offsprings.
A gene is a nucleotide sequence found on a chromosome which determines a trait in an individual.

Answer:
The path of cellular respiration that occurs in the mitochondria is aerobic.
Explanation:
Aerobic respiration is what uses oxygen to extract energy from glucose. It is carried out inside cells, in organelles called mitochondria, through which chemical energy is obtained from the breakdown of organic molecules.
To obtain glucose energy, a process occurs in which the carbon is oxidized and when it reaches the mitochondria it mixes with the water making a chemical compound called glucositisa ( pathway responsible for oxidizing glucose to obtain energy for the cell) in which the oxygen from the air is the oxidant used.
Aerobic respiration is a process consisting of chemical reactions that are grouped into 3 stages, taking into account the place of the cell in which each one develops.
1) Glucolisis: It is carried out in the cytoplasm.
2) Krebs Cycle: It is produced in the mitochondria matrix.
3) Respiratory Chain: Occurs in mitochondrial ridges.
Answer:
There would be no seasons anywhere on Earth
Explanation:
If the Earth's axis was not tilting and it was at a 90 degrees angle relative to its orbit, then the seasons on Earth would disappear. The climate on the planet would be defined by the latitude. The equator and the areas close to it would always have summer, as they will receive direct sunlight throughout all of the year. The mid-latitudes will always have temperate climate, reminding of spring and autumn, as the sunlight will not be very direct, but it will also not be very dispersed, jut enough to create a constantly pleasant climate. The higher latitudes will always have winter, as the sunlight will come at a very low angle throughout all of the year, thus it will be very dispersed, not enough to ever warm this parts enough, so they will constantly be under ice.
Answer:
Answer would be no.
B)carbon, hydrogen and oxygen
