Answer:
Following are the evidences that support human evolution by natural selection:
i) Biogeography
ii)The fossil record
iii) Molecular Biology
Explanation:
i) Biogeography: it was the geographical distribution of species that was first suggested the idea of evolution to Darwin.
ii) The fossil Record: The succession of fossil forms is strong evidence in a favor of evolution. It provides a visual record in a complete series showing the evolution of an organism.
iii) Molecular biology: Evolutionary relationships among species are reflected in their DNA and proteins, in their genes and gene products.
education is a process of giving or receiving systematic instructions usually by a teacher or profesor at a school
biology is the study of life
Answer:2.)One start codon and one stop codon are used for its synthesis.
3.)The piece of genetic code used for its production contains 11 codons.
Explanation: A codon is a nucleotide sequence on the mRNA that is made up of three nucleotides molecules. A codon is a nucleotide sequence that codes for a specific amino acid. Every amino acid is coded for by at least one codon. Some amino acids are coded for by more than one codon.
During protein synthesis, every protein is synthesized using one start codon and one stop codon. A start codon signals the beginning of translation while the stop codon signals the end of translation. The start codon codes for methionine while the stop codon codes for no amino acid. Therefore, a protein whose genetic sequence has 11 codons is synthesized using a piece of genetic code containing 11 codons.
Answer:
Answer is Telophase.
Explanation:
At the telophase stage, the DNA unwind to strands, when the chromosomes arrive arrive at the opposite pole. The spindle fibers also disappear, and the nuclear membrane reappear.
Answer:
It affects life on Earth by causing the heat rays of the sun weaker.
Explanation:
The ozone layer acts as a shield for life on Earth. The stratospheric ozone layer absorbs ultraviolet (UV) radiation, preventing dangerous UV rays from hitting Earth's surface and harming living organisms.
