Limestone: Flaky and mainly made of bones.
Shale: Fine grained and made of clay fragments.
Flint: Hard rock made up of mineral quartz. Also can be used to make fire (flint and steel)
Hope this helped you!
The answer is Lactobacillus because it is a bacteria and that's what prokreatic cells are.
Yes, I agree with statement b/c in meiosis I, specifically in prophase I the homologous chromosomes line and form tetrads in which they exhibit the act of ‘crossing over’ which allows for genetic diversity; This would not occur in mitosis as body cells are produced to repair or for growth so the division of cells must allow for the exact replication of DNA or it is not possible to repair the body or growth if there is genetic variation in each cell. Also, in Meiosis I, specifically when metaphase I occurs, it is impossible to predict how the homologous chromosomes will be split, therefore creating even more diversity of genes known as Independent assortment. None of these processes occur in meiosis II, as the exchange of DNA and act of genetic diversity has already occurred in Meiosis I, therefore Meiosis II simply has to go throwing regular cell division making it more similar to mitosis than Meiosis I; Independent assortment and crossing over are the processes that set Meiosis I to differ from the others.
(Go into more depth about how body cells have to be completely identical whereas gametes have to have genetic diversity)
An ecosystem composes of an environment and the organisms that interact with said environment. Changing temperature leads to an unstable ecosystem because of two things; failure of adaptation for the environment, or failure of adaptations for the animals.
If the environment fails to adapt to a change in temperature, plants will die, thus causing herbivores to die and the whole food web/chain to disrupt. (Im not really going in to deep detail, but plants can die from the soil failing to fertilize.)
For animals, it may also disrupt the food chain, but natural resources such as water may be needed more in the heat. If said animal doesnt have the adaptations to compete in such an event, they die. Also, especially if the environment was previously a desert, all adaptations will be useless, and other animals will start to move in. More competition. Not only that, if the ecosystems temperature decreases, for example, many animals might die from the cold and such. They do not hibernate/ have the adaptations of an animal that lives in the cold.
All in all, changing temperature can cause an unstable ecosystem because it can disrupt the food chain/web, kill plants, kill animals, cause an increase of animals, cause a decrees of natural resources (such as water) and much more.

I believe D because non of the answers above are reality, humans are great at living in different types of environments and even tend to change there environment.
