Answer: The water in the earth is older than earth itself.The water inside earth came out as steam from volcanic vents and the clouds rained down water..Comets also contain lot of water ice.Early period of solar system large amount of comets and asteroids hit the earth They also brought lot of water.
Explanation:
Answer:
Insertion
Explanation:
Mutation is a phenomenon in which the nucleotide sequence of a gene in DNA is changed into a new sequence due to insertion, deletion or exchange of a gene segment.
Insertion is a type of mutation in which one or more than pne base sequence in added into the DNA of an organism. This insertion may or may not be dangerous depending on the place of insertion and how it is causing adverse effects on the protein product of the gene.
Here is an example of insertion mutation:
Base sequence: AUG GCC TGC
Product: met ala gln
Insertion:
Base sequence: AUG GCC C TG C
Product: met ala Leu
So we can see that the product protein is changed because of insertion.
Hope it helps!
Answer:
true
Explanation:
glucose is the primary nutrient for all living things
The right answer is to perform photosynthesis (more precisely to convert ADP to ATP by ATP synthase).
Light comes to us in the form of photons. These photons have a different energy potential depending on their wavelength.
When a pigment picks up a photon corresponding to its absorption capacity, one of its electrons goes into the excited state. This energy can be transmitted in 3 ways: either by spreading it in the form of photon or heat; both ways lose energy. The third is to transmit resonance energy and there is almost no loss of energy.
A photosystem consists of a reaction center and a collector antenna to optimize the absorption of photons triggering photochemical reactions in order to operate the ATP synthase to produce ATP in the presence of a hydrogen gradient.
Answer:
north pole area
Explanation:
1. The north pole (very northern canada greenland and russia) is a big part of the world, but it's growing smaller
2. It's all mostly ice, so barely any trees
3. SUPER cold there, so it doesn't get warmer than 50 f or 10 c
5. The north pole area's ocean is called the Arctic Ocean
6. the aurora lights, or the Northern lights happen there too.
