A. Water being pumped in and out of guard cells.
Answer: Replication
Explanation: When the cell is preparing to divide it will <u>replicate</u> its DNA so that both of the daughter cells will have a complete set of the DNA. It's like a book of instructions and the cell has to perfectly replicate it so that when it splits into two both of the new cells will have a perfectly made copy of it! Hope this helps :)
The correct sentences are the following:
A) Antibiotic resistance in bacterial populations is caused by natural selection of bacteria that inherit mutations that make them resistant to the antibiotics.
C) Crossing-over causes a shuffling of allele combinations during meiosis as the alleles from each parent form new combinations on homologous chromosomes.
E) When two bacteria are linked during conjugation, the donor cell passes DNA to the recipient cell which causes genetic recombination.
Explanation:
These three options are associated with the generation and preservation of genetic diversity
They must occur in the DNA, which is in each cells nucleus. More specifically the nucleolus of the cell. A mutation occurs in an allele, where a base triplet (or a codon) gets transcribed incorrectly.
The answer is D, all of the above.
