Answer:Characteristics of Protists.
Explanation: Like all other eukaryotes, protists have a nucleus containing their DNA. They also have other membrane-bound organelles, such as mitochondria and the endoplasmic reticulum. Most protists are single-celled.
The correct answers are:
- Porosity;
- Moisture;
- Temperature;
The weathering is a process that manages to break up the rocks into smaller pieces. This process and its effectiveness and intensity are dependent on multiple factors.
The porosity of the rock can result in a very quick process of weathering. The reason for that is that the water will be able to get inside the rock, thus reacting chemically, but also if the temperatures are very low and it freezes, it will create a pressure inside the rock that will result in cracking.
The moisture is also important factor because the more water vapor there is in the air, the more the chemical reaction with the rocks.
The temperature is very importation because it can affect the rock with both very high and very low temperatures, to widen it little and than to tighten it little, which will eventually cause the rock to break up.
The complete question goes like this :
<span>Almost every major city in the world has a zoo. Humans have kept and enjoyed animals since the prehistoric times. Ancient Greeks and Romans kept small zoos. Over the past fifty years, zoos have changed remarkably. Today zoos provide the animals with larger and more natural habitats.
</span><span>Which sentence could be added to the passage as a supporting detail?
</span>The correct answer is <span>A) Zoos also provide great research facilities
This sentence is adding more information directly related to the state of the zoo in modern times. Besides the educational and entertaining purposes, the zoos are now becoming important centres for research and places for developing conservation strategies for endangered animals. All of the other sentences are not relevant to the importance and characteristic of modern-day zoos. </span>
When there is a cut on your skin, it gives bacteria and other organisms a gateway to enter directly into your bloodstream and could harm the body. By cleaning the wound, you prevent disease and infections from the bacteria.
