Answer: Higher than the concentration in water.
Cells use both diffusion and osmosis to get rid if their wastes. One way is to temporarily convert the waste product into a different molecule.
Explanation: The bigger the difference in concentration is between two places, the faster the molecules will want to move to the place of lower concentration.
Answer:
D. all of the above
Explanation:
Australopithecus (first ape-man): Australopithecus is considered as the connecting link between apes and man as they shared the characteristics of both. The fossil records shows that they appeared around 5 million years ago. <em>Australopithecus africanus</em> was about 1.5 meters high and had human as well as ape like features. It was with bipedal locomotion, omnivorous in their diet and had erect posture. It had human like teeth with small canines and large chewing teeth. The brain was more like an ape with the brain capacity of about 500 cc similar to that of an ape. He lived in caves, had projected brow ridges with no chin. Its believed that <em>Australopithecus africanus</em> gave rise to <em>Homo habilis</em> about 2 million years ago.
The earliest species of Homo genus is <em>Homo habilis</em>. They were skill full man also called as handy man or the tool maker. He had erect posture with bipedal locomotion. The teeth were like modern man. He was skilled and made tools with stones. Slowly with evolution the prognathous face changed to orthognathous in cro magnon (<em>Homo sapiens fossilis</em>).
Answer:
5 Facts
Explanation:
1. When it comes to chemical weathering, it’s all about chemistry. By looking at the term “chemical weathering,” you can see that a chemical reaction causes something to break down or “weather.” That “something” is rocks and minerals.
2. In chemical weathering, rocks and minerals are reacting to acids, oxygen, carbon and water. That’s why no two rocks ever look exactly the same. It’s also the reason that we have those awesome looking caves and unique rock formations all over the world.
3. While chemical weathering creates nifty formations, the way it breaks down rocks also causes fractures in ancient structures like the Great Sphinx of Egypt. It also causes the surface to break down on gravestones.
4. Chemical weathering types can work separately, but they often work together to create landforms and break down minerals.
5. Acid rain caused by pollution such as factory and car exhaust is another agent of chemical weathering.
D: it’s typically associated with cloudy weather and precipitation.
The father of this offspring should be male 3. It is the only individual that exhibits certain molecular genetic markers present in the offspring but absents in the mother.
<h3>Genetic markers</h3>
A molecular genetic marker is a fragment of DNA that can be used to trace the inheritance pattern from parents to offspring.
In this case, parents and offspring exhibit three molecular markers which are shared among them.
There are certain genetic markers that are present in the offspring but they are absent in one of the parents, and therefore they can be used to trace the inheritance pattern.
