choose a plant or animal that you think is interesting. describe some of the threats or challenges
Answer:
If I were to choose a plant or animal which is interesting, I'd choose the "cactus."
Explanation:
A "cactus" is truly a splendid plant owing to its ability to survive in the desert or periods of drought. Growing them is also not that challenging or difficult. However, this plant is prone to certain threats that may lead to its extinction.
One of these threats is the "over-collection of cacti." Due to its versatile use, the cactus is often sold as an ornamental plant. Another threat is the number of pests, such as snails and slugs, that attacks it yearly. It is a delicious food for mealy bugs, red spider mites, gnats, flies, etc.People often misunderstand the cactus' water level needs. Some people over-water the plant and this often results to the bacteria, virus and fungi being attracted to it.Water Hyacinth
Water Hyacinth grows profusely, forming dense mats that can spread across water surfaces eventually blocking the entire water body.
It can eliminate native wetlands and waterways and kill aboriginal fish and other wildlife.
Also, it causes a high evaporation rate and loss of water and degrades water quality.
What are the natural predators of the water hyacinth?
Water hyacinth is native to South America, the only continent where natural predators such as weevils and moths keep it at bay.
Thus, these are some of the threats or challenges of water hyacinth.

Answer:
A. the temp of the water
Explanation:
a sediment core from the JOIDES Resolution, an ocean-going ship that has collected many sediment cores that record Earth’s past climate.
The ratio of the two isotopes in foraminifera shells is affected by temperature.
What is temperature?Temperature is the degree of coldness or hotness of an object or a particular place.
Isotopes are atoms of the same element with different masses.
The factors affecting the ratio of isotopes of elements depends on the Half-Life of the isotopes as well as temperature.
Temperature will make the rate of decomposition reaction faster.

Explanation:
why is it easy for a virus to mutate?
Answer:
Viruses mutate very quickly The major reason that viruses evolve faster than say, mosquitoes or snakes or bed bugs, is because they multiply faster than other organisms. And that means every new individual is an opportunity for new mutations as they make a copy of their genetic material. Many of those mutations have no noticeable effect.

Explanation:
which fossil record would likely show more diversity in-living organisms of marine organisms?
Answer:
The correct answer is desert-dwelling species.
Explanation:
Any preserved remains, trace or impression of anything, which was once living in the past is termed as a fossil. The examples of fossils comprise stone imprints of microbes or animals, bones, exoskeletons, shells, coral, remnants of DNA, the substances getting preserved in amber, and others.
For the formation of fossils, the most essential condition is decomposition that takes place gradually, that is, at a slow pace. Thus, places like wet marshy areas will be the locations where the maximum of the fossils can be found as such places provide optimum conditions for slow mineralization and decomposition of bones.
