Explain natural selection and adaptations of bacteria

Biology
1 answer:
faust18 [17]3 years ago
6 0

Natural selection can cause speciation, which increases the biodiversity of an ecosystem. Several bacterial colonies are placed on a petri dish that contains agar with antibiotics. After 24 hours, ninety percent of the original bacteria die, but the remaining ten percent survive and later reproduce.

A hypothetical three-step metabolic pathway consists of the intermediates W, X, Y, and Z, and the enzymes that catalyze the reac
GenaCL600 [577]

Answer:

ZBWCYAX

Explanation:

Equation for the intermediates: Z↔W↔Y↔X

1) B catalyzes the breakdown of Z, therefore inhibiting B leads to the build up of Z.

2) If enzyme C is inactive then the organism will not  receive Y to grow, thus Y is a by-product of C.

3) If A is inhibited then W, Y and Z build except for X, thus it make sense that A catalyzes a reaction that leads to X as a by-product.

4) Inhibiting C leads to the reaction toward making Z and W, thus it catalyzes the breakdown of C directly and Z indirectly.

Ludmilka [50]
Photosynthesis is when plants turn light from the sun into food (energy). The light from the sun is turned into energy by using chlorophyll. Chlorophyll absorbs blue and red light to turn Co2 and H2o into glucose.

skelet666 [1.2K]

Answer:

Exergonic reaction

Explanation:

  • A chemical reaction which is associated with a release of energy and thus, is associated with a negative free energy change is said to be an exergonic reaction.
  • An exergonic reaction owing to the negative free energy change is a spontaneous reaction.
  • The energy that is released in the exergonic reaction is usually observed  in the form of heat and light.
  • The energy is released due to the breaking of the chemical bonds.
  • Therefore, on burning of the firewood the bonds between the glucose molecules break up which leads to the release of energy in the form of heat and light and this is thus, an example of an exergonic reaction.
