Mitosis and meiosis have different impacts on the ability of a population to evolve. Mitosis is the process of cell division that produces two identical daughter cells, each with the same number and type of chromosomes as the parent cell.

This means that mitosis does not create genetic diversity within a population, which is a key component of evolution. Therefore, mitosis alone does not have a significant impact on the ability of a population to evolve.

On the other hand, meiosis is the process of cell division that produces four haploid daughter cells with unique combinations of genetic material. This genetic recombination creates genetic diversity within a population, which is essential for evolution to occur. Meiosis allows for the shuffling of alleles, resulting in new combinations that may be advantageous, disadvantageous or neutral for the organism.

Thus, meiosis plays a crucial role in the ability of a population to evolve by creating genetic variation that can be acted upon by natural selection.

Indeterminate.

Explanation:

Beefsteak tomatoes are indeterminate.

Beefsteak tomatoes are indeterminate.

Indeterminate tomato plants have a continuous growth habit, which means they will grow, flower, and set fruit indefinitely throughout the growing season until stopped by frost, disease, or other environmental factors.

On the other hand, determinate tomato plants grow to a certain height, flower, and set fruit all at once within a relatively short period, usually a few weeks. They then stop growing and producing fruit, making them suitable for small gardens or container gardening.

Beefsteak tomatoes are a popular variety of indeterminate tomatoes known for their large size and flavorful fruit. They are typically grown in large gardens or farms where they have plenty of space to grow and require support to keep the fruit off the ground.

Based on your question, it appears that you are referring to a graph that compares the rate of blood flow through different organs at rest and during exercise.

Blood flow increases during exercise to provide oxygen and nutrients to the working muscles and to remove waste products. At rest, organs like the brain and kidneys receive a higher percentage of blood flow, while during exercise, a greater portion is redirected to the skeletal muscles to meet their increased demands.

The specific distribution of blood flow during exercise depends on factors such as exercise intensity, duration, and individual fitness levels.

As exercise intensity increases, the demand for oxygen and nutrients in the muscles becomes more significant, leading to a greater redistribution of blood flow to meet those demands.

Overall, the graph comparing blood flow at rest and during exercise would typically show an increase in blood flow to the skeletal muscles and a relative decrease in blood flow to non-essential organs.

This redistribution of blood flow is essential for optimizing performance and ensuring efficient oxygen and nutrient delivery to the working tissues.

It's worth noting that the regulation of blood flow during exercise is a complex process influenced by various factors, including the autonomic nervous system, local metabolic factors, and hormonal control.

These mechanisms work together to ensure that blood flow is appropriately adjusted to meet the demands of different organs and tissues during exercise.

On Principles of Evolution:

Radiometric dating involves using the decay of radioactive isotopes to determine the age of rocks and fossils, while stratigraphy involves the study of rock layers and the order in which they were deposited.

During the Paleozoic era, the continents were clustered together as one large landmass known as Pangaea. During the Mesozoic era, Pangaea began to break apart into smaller continents, and by the end of the era, the continents were in positions similar to their current locations. During the Cenozoic era, the continents continued to move and drift apart, forming the modern configuration we see today.

Lamarck's theory of evolution, also known as the theory of inheritance of acquired characteristics, states that organisms can pass on traits acquired during their lifetime to their offspring. The strengths of this theory are that it was one of the first to propose a mechanism for evolution, and it emphasized the importance of the environment in shaping organisms. However, the theory has several weaknesses, such as the lack of evidence supporting the idea that acquired traits can be passed on genetically, and the fact that some traits are determined by genes rather than environmental factors.

False. Dominant alleles do not always increase in frequency because their success is dependent on the environment and the fitness of individuals carrying the allele. If the environment changes, a once-dominant allele may become detrimental and decrease in frequency.

Populations evolve because they are subject to natural selection, genetic drift, gene flow, and mutation. These factors can cause changes in allele frequencies over time, leading to the evolution of the population. Individuals, on the other hand, do not evolve because they cannot change their genetic makeup during their lifetime.

Natural selection is the process by which organisms with advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring. It is a natural process that occurs without human intervention. Artificial selection, on the other hand, is the process by which humans intentionally breed plants or animals for specific traits. Humans selectively choose individuals with desirable traits to mate and produce offspring with those traits.

The given statement "Mic determines how much antimicrobial agent to use in vivo" is false. The correct option is (b).

MIC stands for Minimum Inhibitory Concentration, which is the lowest concentration of a particular antimicrobial agent that inhibits the visible growth of microorganisms in vitro.

It helps to determine the appropriate dosage and duration of antimicrobial therapy. The MIC value is determined through in vitro testing, which involves growing microorganisms in a controlled environment with various concentrations of antimicrobial agents.

In vivo, the appropriate dosage and duration of antimicrobial therapy are determined based on several factors such as the patient's age, weight, immune system status, renal function, and the type of infection.

The recommended dosage may also vary based on the severity of the infection, the causative microorganism, and the susceptibility of the microorganism to the antimicrobial agent.

Therefore, MIC helps to determine the susceptibility of a microorganism to a particular antimicrobial agent, but it does not directly determine the appropriate dosage and duration of antimicrobial therapy to be used in vivo.

The determination of the dosage and duration of antimicrobial therapy requires a comprehensive evaluation of several factors related to the patient and the infection.

Explanation:

During muscle contractions, thin filaments are pulled towards the center of the sarcomere by the myosin heads of the thick filaments. Muscle contraction occurs when the myosin heads attach to the actin binding sites on the thin filaments, forming cross-bridges.

The sliding filament theory explains how muscle contraction occurs. According to this theory, the sarcomere, which is the basic functional unit of a muscle, shortens during contraction because the thin filaments slide over the thick filaments.

The myosin heads attach to the actin binding sites on the thin filaments and pivot, pulling the thin filaments towards the center of the sarcomere. This process is powered by the hydrolysis of ATP molecules, which provides the energy for the myosin heads to move.

Overall, the movement of the thin filaments towards the center of the sarcomere during muscle contraction is a crucial aspect of the sliding filament theory, which provides a mechanistic explanation for how muscle contraction occurs at the molecular level.
