Answer:
Explanation:
The elliptical orbits of planets were indicated by calculations of the orbit of Mars. From this, Kepler inferred that other bodies in the Solar System, including those farther away from the Sun, also have elliptical orbits. The second law helps to establish that when a planet is closer to the Sun, it travels faster.
The principle of independent assortment applies to chromosomes because it states that genes for different traits separate independently during the formation of gametes.
Basically the chromosomes are what separate independently not the genes. <span />
Answer:
Explanation:
All living organisms possess genetic material in form of DNA that holds the information needed to produce useful products (proteins). Amino acids are the building blocks of these proteins. They form a sequence that specifies a particular protein. On the other hand, these amino acid sequences is determined by the sequence of nucleotides in the DNA.
The way by which this information held in DNA is expressed is called GENETIC CODE. The genetic code consists of all the triplet nucleotide called CODONS that specifies amino acids in all living things. This genetic code is Universal i.e. it is employed by virtually all living organisms. A particular CODON specifies the same amino acid in all living organisms. This shows the evolutionary relationship between all living organisms.
Hence, an amino acid sequence can show which sequence of nucleotides encodes it in the genetic code. Since it is the same in all living organisms, it can point out which organism shares evolutionary history.

Explanation:Image result for What is not present in all eukaryotic cells?
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes. However, unlike prokaryotic cells, eukaryotic cells have: a membrane-bound nucleus. numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria)
