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 bacteriophage at any point in time results from _________.A) frequency-dependent selection.
B) heterozygote advantage.
C) stabilizing selection.
D) genetic variation being preserved by diploidy.
E) neutral variation.

Answer: Frequency dependent selection.

Explanation:

Frequency dependent selection can be defined as evolutionary process by which the fitness of the phenotype or genotype is dependent on the genotype or phenotype of the composition of the given population.

Frequency dependent selection is the result of the interaction between the species( parasitism, competition or predation)

It can also lead to the dynamical chaos when the fitness of the individual becomes very low.

Hoochie [10]

The statement that is correct regarding the troposphere and the stratosphere is The ozone layer is in the stratosphere. The third one is true. The ozone layer acts as a protection layer that prevents UV light.

<h3>What are the layers of the atmosphere?</h3>

The atmosphere is divided into many layers, with the troposphere close to the earth and the thermosphere toward the sun, as shown in the diagram. in between two layers, such as the tropopause, which is present between the troposphere and the stratosphere. In the stratosphere, the ozone layer is present, which prevents the sun's UV rays from falling on the earth, and the troposphere is the region where the clouds are formed.

Hence, the correct answer is the third option, which is "The ozone layer is in the stratosphere."

Goryan [66]

Answer:

There are only four parts of skill related fitness in the options; they are:

Speed

Agility

Balance

Coordination

Explanation:

Physical fitness refers to the ability to perform physical activities well without fatigue. In other words, being physically fit refers to a state of general wellbeing. Physical fitness can either be health-related or skill-related. The skill-related components are six in number viz: agility, power, balance, coordination, speed and reaction time.

However, only four of these skill-related parts of physical fitness are mentioned in the options of this question. They are:

- Speed: This refers to the ability to run a distance in a short time frame.

- Agility: This is the ability to move easily and quickly in different directions

- Balance: The ability to maintain an upright body position during training or physical activity

- Coordination: The ability to make physical senses of one's body (eye) cooperate with the limbs (hands and feets) during a physical activity.

Note that, Aerobic Endurance and Muscular strength are health-related components of fitness
