Differences between forsest ecosytem and greenhouse

Answers

Answer 1
Answer: ecosystem (imagine a forest ecosystem) 1. Consists of many species of plants and animals 2. Genetic diversity is very high 3. The sunlight is the energy source for autotrophs and this energy drives all biological cycles 4. Food chains are long and complex 5. Ecological succession takes place in a natural ecosystem over the period of time 6. Natural nutrient cycling ensures maximum and efficient cycling of nutrients 7. Productivity is extremely variable and depends on the environment. In tropical rainforest productivity is very high, but in deserts productivity is very low

Suppose that a large river separates two populations of mice. one population is all black, and the other all white. a beaver dam that is built allows the mice to cross the river. over time, many gray mice are born. what is this an example of?

Answers

In this case two kinds of selection might be applicable to this situation. For example, if the population of grey mice are more exposed to predators due some materials used in the dam then that would be an example of disruptive selection. But if the population of gray mice is less visible to predators and if the population grow, then it will be an example of Stabilizing selection. Basicaly meant, this type of situation is also known as codominancy or codominant type.

Cells can regulate what they need or don't need to maintain their own health. True False

Answers

True. This is called cellular homeostasis. This happens when cells are able to produce and excrete materials within their environment to regulate processes like cellular respiration, phagocytosis, and pinocytosis. If cells are not able to do this, mutations and excessive cellular division may occur causing abnormalities in specific organisms.

The rare earth elements include A. the lanthanide series and the alkali metals.
B. the alkali metals and the transition metals.
C. the actinide series and the alkaline earth metals.
D. the lanthanide series and the actinide series.

Answers

I know that the  rare earth elements (rare earths) - a group of 17 elements consisting of lanthanum, scandium, yttrium and the lanthanides. All these elements - metals silver-white color, while all have similar chemical properties (most common in oxidation state +3). The name "rare earth" is defined in connection with the fact that they are, first, relatively rare in the crust (the content of (1.6-1.7) x 10-2% by weight) and, secondly, to form a refractory substantially water-insoluble oxides (oxides of these at the beginning of the XIX century and formerly known as "lands"). 

That is why the correct answer is D)

Answer: D. the lanthanide series and the actinide series.
