Answer:
The principal difference in development of Dorsoventral axis in deuterostomes and protostomes is something called inversion
Explanation:
In protostomates the neural tube is below the gut and the dorsal vessel is above the gut while in deuterostomates is the oppossite, there is an inversion and now, the neural tube is above the gut and the heart tube is below. In both cases the development is related to the gradient of expression of some genes, where the expresion of one gene supress the formation of one structure in one side of the axis.
In protostomates the TGT-B factor is expressed dorsally and supress neural tube formation and ventrally a sog gene is expressed and supress TGT-F factor allowing neural tube to develop. In deuterostomates, an homolog of TGT-B family gene BMP-4 is expressed ventrally while dorsally BMP inhibitors (sog gene like) are expressed.
Accordingly to some researchers, the first state of the common ancestor of deuterostomates and protostomates had an protostomate-like orientation in dorsoventral axis
Answer:
Glycogen
Explanation:
In humans polysacchride is stored in the form of glycogen and used as a source of energy.
Answer: Independent variable is what is being modified, it is important to compare it to your control group, (which is the original).
Dependent variable is what is being measured, to compare it to the control group to see if your hypothesis works or not.
Explanation: Here's a(n) example:
Bob wanted to take a mint with a mint drop, and he wanted to measure if it can make his breath fresher, but he also wanted to take it with a regular mint to see which is the freshest breath.
Independent variable: Mint drop.
Dependent Variable: Breath (To see if it is going to change with a mint drop.)
Control Group- Regular mint.
<span>The process of photosynthesis is energy-storing because the process converts light energy into chemical energy, which stored in the bonds of glucose.
</span><span>Photosynthesis transforms light into chemical energy that is stored in the form of ATP inside plants. Therefore, it is an energy storage process.

Answer:
Original strand is the old strand and replicated strand is new strand.
Explanation:
DNA is replicated by the semi-conservative way which means the new strand is replicated over the old strand and one DNA duplex has one new strand and one old strand. So the original strand is the old strand and the replicated strand is the strand that is synthesized over the original strand.
In DNA the replicated strand is made by adding nucleotides complementary to the opposite nucleotide present in the template or original strand. Adenine and thymine make complementary base pairing with each other and guanine and cytosine makes complementary base pairing with each other.
