How could natural selection affect humans?

Answers

Answer 1

Answer:

Fish are considered carbon-based organism

Answers

Answer:

Its how you see it.

Explanation:

1.Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously. This quality makes carbon well-suited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and DNA.

2.All life on earth can be thought of as "carbon-based." Just be careful about turning this around backwards. It is true that all living things contain carbon compounds... but the opposite is not true. Just because a certain material is referred to as organic does not mean it is or ever was alive.

In which experimental set up shown would you expect the Elodia plant inside a test tube to produce the least amount of oxygen

Answers

Answer:

Due to less concentration of carbondioxide gas.

Explanation:

Elodia plant inside a test tube produces the least amount of oxygen due to limited carbondioxide gas that is necessary for photosynthesis process. If a test tube has less amount of carbondioxide gas which is a reactant in photosynthesis so in the end the Elodia plant generates less amount of glucose as well as oxygen while on the other hand, if there is more carbondioxide gas is available to Elodia plant, more oxygen as well as glucose is produced.

Answer:

B. A helicase enzyme unwinds the DNA molecule, then corresponding nucleotides are added to the separated original strand forming two separate semiconservative molecules

Explanation:

DNA Replication is an important phenomenon as far as cell division is concerned. It is the process whereby a DNA molecule doubles its content or forms two DNA molecules from one.

In the semi-conservative model of DNA replication, an enzyme called DNA helicase unwinds the double stranded DNA molecule into two single strands. The single strands are then used as template for DNA polymerase to synthesize another molecule of DNA. Hence, two separate DNA molecules comprising of one old strand and one new strand.

Explain how the stomach Depends on other body systems to carry out its role in breaking down food molecules.

Answers

The whole body works together, as a “team.”If one of the parts of the body won’t work together as a team, everything will get messed up. The stomach muscles churn and mix the food with digestive juices that have acids and enzymes, breaking it into much smaller, digestible pieces. An acidic environment is needed for the digestion that takes place in the stomach.
