Planets take in _ and release oxygen gas

Carbon dioxide (CO₂)

Plants use a process called photosynthesis.  During this process, they take CO₂ from the air and water from their roots and combine them.  Then, using energy from sunlight, they convert these ingredients into carbohydrates and oxygen, and the extra oxygen is released into the atmosphere.

The chromosomes of an offspring are related to the chromosomes of the parents, because the chromosomes of the offspring are formed by the combination of genes from their parents' chromosomes.

Explanation:

As we know, reproduction happens with the union of the gametes of two individuals. The gamete of each individual contains half of the genes contained in its chromosomes. When these gametes unite, they give rise to a zygote that will give rise to the offspring.

The genes of the parents of the offspring, therefore, are present in the chromosomes of the offspring, where each individual of the offspring has chromosomes formed by half of the genes of each of their parents.

Thus, we can say that the chromosomes of the offspring are related to the chromosomes of the parents, because the genes of the parents' chromosomes are used to form the chromosomes of the offspring.
