Antibiotic resistance can vary within a population of bacteria. The diagram below represents the changes in a population of bacteria as a result of exposure to antibiotic over time.
Explain how this is an example of natural selection, and why we can use this as evidence that evolution occurs.
Answer:
The resistance that some bacterial populations develop to an antibiotic is an example of natural selection because the individuals with more resistance are those that survive, being an evidence of evolution since resistance can be inherited to the following generations.
Explanation:
The resistance to antibiotics that bacteria develop is the best example of how natural selection and evolution occurs, especially because of the fast and easy reproduction of these microorganisms.
In the example it can be seen that only the the most resistant bacterial populations to the antibiotic survive over time. Antibiotic resistance is due to mutations developed by bacteria that modify their structure and function so that they are not affected by an antimicrobial. According to natural selection, these mutations make resistance an inherited trait, and future generations will not be sensitive to the effect of the drug.
Why does natural selection occur? Only resistant individuals survive the effect of the antibiotic.
How do you explain evolution? Successive generations of bacteria have evolved, through mutations, to resist the effect of an antibiotic.

8. Which of the following are functions of external regulators of the cell cycle?
Select two answers.
a. regulate checkpoints
b. make sure chromosomes have replicated
c. speed up or slow down the cell cycle
d. stop the cell cycle
Speed up or slow down the cell cycle are functions of external regulators of the cell cycle.
The regulation of cell proliferation, growth and DNA synthesis are controlled by the regulatory machinery of the cell cycle.
Cell cycle progression is activated directly by a series of heterodimers formed by cyclins and cyclin-dependent kinases (CDKs).
Cyclin D, by forming a complex with the cyclin-dependent kinases CDK4, activates the action of the kinase whose main substrate is the Rb protein. Cyclin D are proteins that respond to external signals in cells and execute responses such as acceleration of the cell cycle.Cyclin D1 is a protein encoded by the CCND1 gene this acts on the cell cycle by accelerating the G1 phase.In the hypophosphorylated state, the Rb tumor suppressor protein is active and performs its function by inhibiting cell cycle progression.Therefore, we can conclude that speed up or slow down the cell cycle are functions of external regulators of the cell cycle.

How do adaptations affect organisms such as orchid plants
Answer:
Orchids are very well-adapted to life in the canopy. They have roots with a large surface area for rapid absorption of nutrients and water. Their secondary stems can hold stores of water so the plant can withstand periods of drying. ... Orchids also utilize insects to spread their pollen.

During the light dependent reaction,_____ is oxidized to form oxygen. During the light independent reaction, _____
Is reduced to form glucose
Answer:
In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The light-dependent reactions release oxygen as a byproduct as water is broken apart.
