What evidence in pea plant crosses supported Mendel's law of independent assortment? When crossing hybrid pea plants, some of the offspring exhibit traits that are not exhibited in the
parents.
O When crossing pea plants that differ in two characteristics, traits produced by dominant factors
always appear together.
O When crossing true-breeding pea plants, all of the offspring exhibit traits that are exhibited in the
parents.
O When crossing pea plants that differ in two characteristics, traits produced by dominant factors do
not necessarily appear together.

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.

propane is burned to provide the heat in many cooking grills. the chemical reaction for this process is shown in the equation below.

c3h8 + 5o2 ? 3 co2 + 4h2o + energy

what are the products in this chemical reaction?

3co2 + 4h2o + energy
