<span>The sunspots are eruptions of heat and light energy emitting from the surface of the sun. These can increase our energy absorption many times above normal. Especially if it is pointed directly at the earth. These have been known to disrupt several bands in the radio spectrum and have knocked out communications of satellites. Naturally all this energy would have a great effect on our earth in many ways, climate included.</span>
The correct answer would be D. Mollusca.
The question is basically describing a snail.
Arthropoda have segmented bodies.
Echinodermata(starfishes, sand dollars etc.) are radially symmetrical.
Also none of them have shells except phylum Mollusca :)
This means that we all are the descendants of one ancestor !! thus our genes match !!
Answer: B
Explanation:
Honestly, I would say a word. Since it states that codons are read by mRNA molecules in groups of three, they could be easily compared to words, not letters.
Wind power:
Advantages:
-Using wind as a source of power is very cost-effective. This is method is fuel free and the electricity harvested from wind farms is sold at a fixed price over a long period of time.
-Wind power is a clean fuel source. Using wind as a source of power prevents air pollution unlike power plants that mostly rely on fossil fuels which releases toxins into the hair causing both environmental and health problems.
-Wind power is a sustainable source of power since nothing can really stop it from being produced. Since this source of power relies on air, as long as there is air, energy can be harvested.
Disadvantages:
-Wind turbines are usually built in rural areas due to the size of them and the amount of space needed to build them. Because of this, they aren’t usually close to cities or remote locations where the energy harvested from them is most needed.
-Wind turbines can harmfully impact nature. Because of their height and size, many birds and other flying animals end up getting killed by the spinning blades connected to the turbine.
-Locations to build wind turbines may be hard to get due to competition with other things that may be of more importance on the land compared to wind farms.
