Answer:
Fraternal twins are from two seperate eggs.
Explanation:
The first part of the question is missing but any difference between fraternal twins can be explained by the fact that two seperate eggs are fertilized during the pregnancy so they have different genomes which leads to having different dominance of different genes and this leads to different expressions of this genes.
I hope this answer helps.
Energy from the sun reaches Earth by way of radiation.
The sun cannot conduct heat to the Earth directly because the two bodies are not in contact with each other. Convection is also impossible, as no medium connects the two bodies to facilitate heat flow. Instead, the sun radiates much of its energy as light of various wavelengths. Some of this radiated light is in the infrared part of the spectrum and reaches Earth as heat.
Light in the visible part of the spectrum also has the effect of warming the Earth. It does this by penetrating the atmosphere and being absorbed by the land and water. Once the Earth has absorbed all of the energy it can hold, it begins to radiate energy back toward space. This terrestrial radiation is primarily in the infrared band of the spectrum, which is absorbed by aerosols in the atmosphere. These greenhouse gases trap heat and store up the surplus energy of the Earth's allotment of solar radiation. Eventually, even the atmosphere reaches thermal saturation and radiates waste energy back out into space.

Answer:
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.
Explanation:
Answer:
- Both DNA, which stores genetic information and encodes protein sequences, and RNA, which is involved in the direct production of proteins, are nucleic acids.
- Nucleic acids always consist of a five-carbon sugar, a nitrogenous base, and one or more phosphate groups.
Explanation:
DNA and RNA are both made up of chains of nucleotides. They are responsible for holding, transmitting, and translating genetic information into proteins.
Nucleotides are made up of a 5 carbon sugar, (DNA is deoxyribose, RNA is ribose), a phosphate group, and a nitrogenous base. They are linked together by phosphodiester bonds. The sequence of nucleotides makes the DNA and RNA sequences unique and determines the structure and function of the encoded proteins
