Answer:
This method is used for separating bran from flour, sand from gravel, pearls of different sizes, etc. Winnowing:The process of separation of lighter particles from heavier particles; with the help of wind; is called winnowing. This method is also used for separating grains from husk.
Answer: Dominant
Explanation: If the trait is dominant, one of the parents must have the trait. Dominant traits will not skip a generation. If the trait is recessive, neither parent is required to have the trait since they can be heterozygous. Determine if the chart shows an autosomal or sex-linked (usually X-linked) trait.
Answer:
An amino acid can be encoded by more than one codon.
Explanation:
Codons are triplets of nucleotides in mRNA that are used for the protein synthesis (translation). A codon specifies a single amino acid, but there are exceptions. tRNA molecule contain anticodons, triplets of nucleotides that are complementary to codons. So, during the translation, tRNA carries the amino acid, that corresponds to the codon in mRNA.
Degenerate genetic code (more than one codon can code for the same amino acid) is important, because when point mutation occurs it is possible that the amino acid remains unchanged.
Answer:
Compound: These are made of the various type of same or different elements. These elements show a specific ratio in a particular compound.
The physical properties are traits of a particular compound or element that can be observed physically like the state of matter, color, odor, and other. The chemical properties and physical properties of compounds and elements they formed are different.
It is not comparable as the elements have no or very little individual value in a compound. For instance, water made of hydrogen and oxygen, where water is liquid and constituents are gas.
Many trees are evergreen so that plants can photosynthesize right away when temperature rise, many trees that have needle-like leaves which shape losses less water and sheds snow more easily than broad leaves waxy coating on needle-like prevent evaporation need-like leaves are dark in color allowing solar heat to absorbed many trees have branches that droop downward to help shed excess snow to keep the branches from breaking.
