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.

Explanation:
Answer:
If it carries two identical copies of the recessive trait.
Explanation:
Answer:
Cells become cancer cells largely because of mutations in their genes. Often many mutations are needed before a cell becomes a cancer cell. The mutations may affect different genes that control cell growth and division. Some of these genes are called tumor suppressor genes.
Explanation:
Here are the answer for each item.
1. With each cell division, chromosomes gradually shorten in the absence of telomerase activity (FALSE)2. During embryonic and childhood development in humans, telomerase activity is relatively low compared to the level of activity in most somatic cells of an adult. (FALSE)
3. <span>Cells that divide frequently tend to have relatively low levels of telomerase.(FALSE).
</span><span>4. The activity of telomerase in most mature somatic cells is kept high by increasing the expression of the gene encoding this enzyme. (FALSE)
5. Mice with low telomerase activity appear to be normal for up to six generations, but they show steadily decreasing telomere length that eventually leads to nonviable offspring. (FALSE)
6. When telomerase is added to cells grown in culture, their lifespan decreases relative to controls that have no telomerase added. (FALSE)
7. Cancer cells generally have high levels of telomerase activity, which allows them to divide indefinitely without the chromosomes getting shorter and shorter. (TRUE).</span>
