Answer: option B - some gametes may have an extra copy of some genes.

Explanation:

Actually, nondisjunction occurs in meiosis and results in FOUR ABNORMAL GAMETES/DAUGHTER CELLS: two gametes have an EXTRA copy of gene e.g XXY, while two other gametes LACK a required copy e.g XO

So, the right answer is some gametes may have an extra copy of some genes.

Does the water cycle, the nitrogen cycle, and the carbon-oxygen cycle play a role in ecosystem balance? Explain.
Anika [276]

Explanation: The water cycle is also known as the hydrological cycle. It describes how water moves on, above, or just below the surface of our planet. Water molecules move between various locations - such as rivers, oceans and the atmosphere - by specific processes. Water can change state. Nitrogen compounds found in cells include proteins. Nitrogen from the air is converted into soluble ions that plant roots can absorb. It forms part of nitrogen compounds in the plants, and is then passed from one organism to the next. It is returned to the atmosphere as nitrogen gas. This is the nitrogen cycle. The carbon-oxygen cycle is the process by which plants use carbon dioxide for respiration during photosynthesis and produce oxygen. During this process, carbon dioxide becomes part of the plant, and when the plant dies in a carbon-rich state it is possible for it to become a fossil fuel.
