Answer:
The correct answer will be- phloem transports photsynthetic products to the roots
Explanation:
Phloem is the vascular tissue which specializes in transporting the solute molecules like sugar in the form of sucrose to in the plants.
The phloem connects the photosynthetic organ (Leaves) to non-photosynthetic organs (stem and roots) of the plants by transporting the photosynthates or sucrose to various parts.
Since the roots also need the energy to perform metabolic functions so need the photosynthates to synthesize the energy molecule. They receive the photosynthates from the phloem.
Thus, phloem transports photosynthetic products to the roots is the correct answer.
Answer:
it gives a greater variety of crops
Answer:
also increase
Explanation:
more food more animals can eat causing animals to come and also breed then the crickets will go back down causing the predators to go back down giving them a chance to go back up and the cycle continues.
Accoring to the Chargaff's first rule of base pairing, each of the four nucleotide bases has its own complimentary match, that it always bids with.
So, Adenine always bonds with Thymine and Cytosine always binds with Guanine.
If you know the concentration of one base, in our case Cytosine, then you can easily calculate the percentage of other bases.
Since Cytosine and Thymine are always paired, there is an equal amount of both of them -16%.
So, 16% C + 16G = 32% of the whole DNA.
This means that the other two base pairs A and T make up to 68% of the DNA.
Half of the 68% is Adenine = 34% and half of it is Thymine- 34%.
So, the percentages of base pairs in the DNA sequence are :
16% C
16% G
34 % A
34 % T
