The restriction enzymes of bacteria protect the bacteria from successful attack by bacteriophages, whose genomes can be degraded

by the restriction enzymes. The bacterial genomes are not vulnerable to these restriction enzymes because bacterial DNA is methylated. This situation selects for bacteriophages whose genomes are also methylated. As new strains of resistant bacteriophages become more prevalent, this in turn selects for bacteria whose genomes are not methylated and whose restriction enzymes instead degrade methylated DNA. The outcome of the conflict between bacteria and bacteriophages at any point in time results from ________.

<h2>Frequency-Dependent Selection</h2>

Explanation:

  • Frequency-dependent selection can be determined in a variety of ways, which are not different, yet all convey the feeling that the wellness of a phenotype or genotype changes with the phenotypic or genotypic structure of the population. Such determination can promptly keep up phenotypic variety and hereditary variety at a solitary locus. The support of polygenic variety with recurrence subordinate determination are to some degree more prohibitive than in the single locus case
  • Utilizing a recreation model, Mani et al. (1990) investigated the consolidated impact of change, balancing out ward choice, and recurrence subordinate determination on a hereditary framework in which there are n (≤12) loci, each with up to 32 alleles that demonstration additively, the i allele contributing an amount I to the genotypic variation
  • Hence, the right answer for the fill up the blanks is "Frequency-Dependent Selection"

Eutrophication can cause excess algae growth. Which of the following describes how nutrients contribute to eutrophication?
dusya [7]

Eutrophication of water bodies like lake, pond, shallow stretches of river, etc. is the phenomenon where excess growth of vegetation on the surface of the water takes place. This excess growth results in the clouding of the water, depletion of dissolved oxygen in water, and the death of aquatic organisms. The primary reason for the cause of eutrophication is the presence of nutrients in excess amounts in the water. The nutrients B. come from fertilizer and sewage runoff.
