Answer:
The star sm0313, was discovered using the ANU skymapper telescope at the siding spring observatory and later confirmed by the megellan telescope in Chile. Somewhat surprisingly, it's located a "mere" 6,000 thousand light-years away, they origins date back to the beginning of time.
Answer:
i think they are orignally from cold areas so they store water and moisture in there needles. and they stay green year round.
Explanation:
A balance of this two process must be maintained in order to attain a constant earth temperature.
<h3>
Energy flow in the earth</h3>
The earth in itself is a massive ecosystem. Energy flows into the earth and out of it. The only source of energy input to the earth is the sun. Also, energy is lost from the earth via re-radiation of energy in the form of infrared rays.
However, this inflow and out flow of energy affects the temperature of the earth. A balance of this two process must be maintained in order to attain a constant earth temperature.

The wood in a matchstick is made of cellulose, a polymer of glucose molecules. When you light the matchstick, heat and light are given off, indicating that an exothermic reaction is occurring.
There are two types of reactions:
1. Exothermic reactions: In these reactions, the reactants combine to form product and heat is liberated. Example, burning of fuel.
2.Endothermic reactions: In these reactions, the reactants combine to form product and heat gets absorbed from the surroundings. Example, photosynthesis in plants where the energy of the Sun gets absorbed.
Answer:
Meiosis is a process in which sex cells, also known as gametes are made. Meiosis is different from mitosis in a lot of ways, one being that mitosis creates identical daughter cells and meiosis creates unique daughter cells. Meiosis is important because it allow for the creation of a meiosis nucleus. Cells produced by meiosis will be used in haploid, where each member of the next generation is genetically unique.
Cells produced in <u>sexual reproduction</u> will have half of the genetic information of body cells and will be genetically <u>unique</u>. This is necessary because when a sperm and an egg fuse together in sexual reproduction. They form a <u>zygote</u>: the first body of a new individual.
The new individual will now have cells that are <u>diploid</u>, meaning they have two sets of chromosomes. They zygote will have to do a lot of <u>mitosis</u> allowing it to grow quickly and ensure that all of its cells are genetically unique.
