The sun shining on a tidal pool during a hot day heats the water, causing some water to evaporate. Because the water has become warmer and saltier, ________.
Answers
Answer: The oxygen content of the water decreases
Explanation:
The sun shining on a tidal pool during a hot day heats the water, causing some water to evaporate. Because the water has become warmer and saltier, the oxygen content of the water decreases.
The temperature and the salt content of a body of water determines how much oxygen it can hold.
The oxygen content of warm water decreases because the temperature of the water causes the water molecules to move faster. This leads to the expulsion of oxygen from the water, making it contain less oxygen.
Also, salty water will lead to a decrease in oxygen because of the presence of sodium chloride ions.
Therefore, a warmer and saltier water will contain a less amount of oxygen.

The following claims correctly describes a kingdom of Domain Eukarya is Kingdom fungi includes organisms that get energy by decomposing materials in their environment.
What are the main features of the Fungi kingdom?Fungi are heterotrophic and eukaryotic organisms that can be unicellular or multicellular. The vast majority of species are filamentous, and these filaments are called hyphae. Some fungi are formed by several densely packed hyphae, which form the so-called mycelium.
The Fungi Kingdom is represented by unicellular or multicellular eukaryotic organisms, being found in the most diverse types of environments. Fungi include mushrooms, molds, wood ears, lichens, among other organisms.

What was the shape of the diffraction pattern of DNA that made them conclude that it was a Double-helix?
Answers
Answer:
The diffraction pattern was as an X
Explanation:
Rosalind Franklin was an X-ray crystallographer who discovered that the DNA molecule existed in a helical conformation. She used X-ray diffraction to determine that the pattern of the DNA molecule was as an X, thus showing that the DNA molecule formed a spiral (i.e., a double helix), which was key in helping Watson and Crick to elucidate the structure of the DNA molecule. Otherwise, if DNA would be a lineal molecule, it would be seen as two dots under X-ray diffraction.

Answers
Answer:
The amount of precipitation reduces by 20% over time. It will have an impact on the habitat because species that have adapted to drier climates will supplant those that are less suited to the new climate.
Explanation:
A combination of conditions (factors) that caused these changes in the habitat are:
Hot summersHarsh wintersCold springs What is a habitat?A habitat refers to a combination of resources and geographical area that defines where the particular species of a living organism such as a rabbit, generally lives and thrives.
In this scenario, a combination of conditions (factors) that caused these changes in the habitat are:
Hot summersHarsh wintersCold springsIn conclusion, these conditions (factors) would kill or make the population of rabbits in this habitat not to reproduce, which may cause them to emigrate.
