Answer:
Antibiotic resistance evolves naturally via natural selection through random mutation, but it could also be engineered by applying an evolutionary stress on a population. Once such a gene is generated, bacteria can then transfer the genetic information in a horizontal fashion (between individuals) by plasmid exchange
Answer:
option A
Explanation:
Cones provide colour vision while rods cells do not produce colour vision. Rods provide the vision in the dull light (darkness or night), whereas cones are known to give the vision during the day or bright light; Rod cells are more sensitive to light than cone cells and both do have visual pigments with the rod cells possessing rhodopsin and the cone cells having photo-opsins.
Answer:
The correct choice is A)
There will be fewer producers in the area.
Explanation:
Very easy to deduce. A producer in biology of ecosystems is an organism that produces its own food. Another word for a producer in biology is 'autotroph'.
They produce energy directly from the energy given off by the sun or chemicals or both.
Grass (or plants) are producers. They do this with the help of water, converting solar energy into sugar or food, which are usable forms of energy.
So the more grass is consumed, the fewer producers in the area.

Answer: A the chromosomes from another parent cell were introduced
Explanation: A child is created when the male sex cell joins the female cell. If the male and female sex cells had the standard number of chromosomes, as is found in body cells then the zygote (baby) would have double that number of chromosomes. The number of chromosomes would keep doubling every generation. To avoid this doubling the parent's body cells split by miosis which halves the number of chromosomes and so when the sex cells join the total number of chromosomes is the same as that found in the parent's body cells.
Answer:
Mutation and Recombination
