The codons that code for alanine in a potato beetle are the same as those that code for alanine in mackerel and humans. This evidence best supports the idea that -(D) different species share components of the genetic code
Explanation:
Evaluating the other options given
A.humans and fish evolved from insects
-This option is incorrect as human and fish did not have a common ancestors.
B.
different species synthesize the same proteins
:No this statement also is not the correct option
C.
insects, fish, and humans express the same genes-The expressed genes cannot be same for different species
Hence the correct answer is
The codons that code for alanine in a potato beetle are the same as those that code for alanine in mackerel and humans. This evidence best supports the idea that -(D) different species share components of the genetic code(As the genetic code is said to be universal
Answer: The primary task of the last stage of cellular respiration, the electron transport chain, is to transfer energy from the electron carriers to even more ATP molecules,
Explanation:
Carbon dioxide (chemical formula CO2) is a colorless and odorless gas that is vital to life on Earth. This naturally occurring chemical compound is made up of a carbon atom contently double bonded to two oxygen atoms. Carbon dioxide exists in Earth's atmosphere as a trace gas at a concentration of about 0.04 percent (400 ppm) by volume.Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, in ice caps and glaciers and also in seawater. It is present in deposits of petroleum and natural gas.

Almost 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium.
