Answer:
1) the genes and chromosomes do not double after each generations because parental sex cells are haploid and only contain one set of chromosomes. During fertilization the two cells fuse to form a diploid zygote with two copies of genes and chromosomes. For example a normal human has 46 chromosomes (2 copies of 23 chromosomes) during reproduction gametes which contain 23 chromosomes (haploid) fuse to form an offspring with the correct number of chromosomes ( 23 + 23 = 46).
2) offspring only receive one set of chromosomes from each parent so to maintain the chromosome number of humans. If this did not happen you would not be the same species.
Answer: d - water forming on the lid under the container
Explanation:
Condensation is the process that describes the change of state of water from gas to liquid. It happens in the water cycle when water vapor gets to the atmosphere and due to the lower temperatures turns into liquid water that then forms clouds.
In the demonstration, the container is meant to be the clouds so when water forms under the container, that is condensation happening because the water vapor has not turned back to liquid after leaving the aquarium water as water vapor.
Answer:
Option D. They use mitochondria to release energy from the sugars.
Explanation:
Mitochondria is an important organelle which is present in both plants and humans. Mitochondria is also called power house of the cell because it release energy in the form of Adenine tri phosphate (ATP) when oxygen is added with the sugar (glucose) during the process of respiration. Energy is also released from glucose molecules in the absence of oxygen but the less energy will be produced.
