Answer:
We have rocks from the Moon (brought back), meteorites, and rocks that we know came from Mars. We can then use radioactive age dating in order to date the ages of the surfaces (when the rocks first formed, i.e. when the lava cooled and crystallized). We also have meteorites from asteroids and can date them, too.

7. Why is it so unlikely for a girl to get a disorder like Duchenne Muscular Dystrophy
Answer:
Because it takes a very long time and an interesting mindset.
Explanation:
People don't really have an explanation for the things that we do they just suddenly build up inside us
Answer:
This is because the mutated gene responsible for Duchenne is located in the X chromosome. Girls have two X chromosomes, meaning that the body usually inactivates the chromosome that carries the mutation. The female will carry the mutation, but manifest little to no symptoms of the disease.
Explanation:
I hope that this helped you ;)

Meiosis has both similarities to and differences from mitosis, which is a cell division process in which a parent cell produces two identical daughter cells.
why do chromosomes become visible during prophase?

In what respect is a mycelium and a fruiting body similar?
Both are made of hyphae.
Both are found above the ground.
Both produce reproductive spores.
Both absorb nutrients underground.
Both produce reproductive spores. Therefore, option (C) is correct.
What are reproductive spores?Reproductive spores are specialized structures produced by certain organisms for the purpose of reproduction. Spores are single cells or groups of cells that are capable of developing into new individuals under suitable conditions. They are typically small, lightweight, and highly resistant to environmental conditions, allowing them to disperse over long distances.
Various organisms produce reproductive spores, including fungi, algae, plants (such as mosses and ferns), and some bacteria. These spores serve as a means of reproduction and dispersal, enabling these organisms to colonize new habitats and propagate their species.
Reproductive spores can be produced through different mechanisms, such as asexual or sexual reproduction. In some cases, spores are released into the surrounding environment and can be carried by wind, water, or other organisms, allowing for widespread distribution and colonization.
