Explanation:

The process of evolution that involves a change in the DNA sequence that leads to evolutionary change is called a mutation.

A mutation is a sudden and lasting alteration in the DNA sequence that can influence genetic variation. Changes in the DNA sequence can influence phenotype, which may or may not have an effect on an organism's fitness. Mutations occur spontaneously, either from errors in DNA replication or from exposure to mutagenic agents. Mutations may happen in either coding or non-coding regions of the DNA, and they can be either silent or expressed.

Evolution is a natural process that results in the gradual change of inherited characteristics in populations over generations. It is the process of alteration in the inherited characteristics of species over successive generations. In other words, it is the process of gradual changes that happen to species over time as they adapt to their environments. It can be defined as a change in the gene frequency in a population over time.

Types of Evolution 1. Natural Selection 2. Genetic Drift 3. Gene Flow 4. Mutation 5. Non-Random Mating 6. Admixture 7. Mutation Pressure 8. Genetic Draft 9. Bottleneck and Founder Effect 10.

Answer:

The genotype of an organism is its complete set of genetic material, two alleles are inherited for a particular gene by your parents sex gametes (sperm + egg). the genotype determines the persons phenotype eg. polydactyly, your eye colour etc, with a recessive or dominant allele. this can be determined through punnet squares too.

The term used to describe the influences of multiple genes on behavior is called "polygenic inheritance."It refers to the transmission of characteristics from one generation to the next in which several genes determine the phenotype of an organism.

When traits or characteristics are determined by more than one gene, they are said to be polygenic. Examples of polygenic inheritance include height, weight, skin color, and eye color. A polygenic inheritance occurs when several genes contribute to a particular trait or characteristic in an organism.

Since most traits are influenced by multiple genes, polygenic inheritance is common in many organisms, including humans. Complex behaviors like language, intelligence, and personality are also believed to have a polygenic basis.

The study of polygenic inheritance is essential for the understanding of complex traits. In most cases, it involves identifying the genes involved in the inheritance of a particular trait, analyzing the interactions between them, and determining how they contribute to the trait's expression.

Polygenic traits tend to exhibit a continuous range of variation rather than discrete categories. That is, the trait is not an either/or situation. Instead, it is a continuum, where individuals fall somewhere along a spectrum.

For example, height in humans is a polygenic trait that shows a continuous distribution of values from short to tall. This continuous distribution results from the combined effects of several genes, each of which contributes a small amount to the overall height of an individual.

The statement that is FALSE is "karyopherins carry macromolecular cargo without NLS sequences out of the nucleus."

Nuclear pores are responsible for the bidirectional transport of proteins into and out of the nucleus. Karyopherins are a family of proteins that facilitate the transport of macromolecules across the nuclear envelope.

They bind tightly to FG repeats, which are found in the nuclear pore complex, and carry macromolecular cargo with nuclear localization signals (NLS) into the nucleus. The Ran protein provides directionality for the transport process by undergoing a conformational change upon GTP hydrolysis.

The GTP concentration is higher in the nucleus than the cytoplasm, which helps to maintain the directionality of transport. However, karyopherins do not carry macromolecular cargo without NLS sequences out of the nucleus.

This statement is FALSE because karyopherins only recognize and transport cargo with NLS sequences.

Newborn babies produce IgM antibodies as their primary class of antibodies.

IgM antibody is one of the five types of immunoglobulin that plays a significant role in the primary immune response. IgM is the first antibody that is produced by the body in response to any infection, making it the primary defense against new infections. In a fetus, IgM antibodies start to appear at the age of 20 weeks in the womb, while in a newborn baby, IgM antibodies are the first type of antibodies to appear.The role of IgM antibodies in a newborn is to provide immunity to the baby for the first few months of life until their own immune system has developed enough to produce its own antibodies. The IgM antibodies pass through the placenta during pregnancy, providing passive immunity to the fetus during the gestation period and in the first few months after birth.

The number of motor units activated is proportional to the amount of tension produced by a skeletal muscle. The correct option is B).

The contraction of a skeletal muscle is controlled by the activation of motor units, which consist of a motor neuron and the muscle fibers it innervates.

1. Motor Units: Motor units are responsible for initiating muscle contractions. When a motor unit is activated by a motor neuron, all the muscle fibers within that motor unit contract together.

2. Recruitment: The number of motor units recruited determines the amount of force or tension produced by a muscle. When greater force is required, more motor units are recruited. This recruitment of motor units is known as motor unit recruitment.

3. Size Principle: Motor units are recruited in a specific order based on the size of the motor neurons. Smaller motor units, which have fewer muscle fibers, are recruited first. As the force requirements increase, larger motor units with more muscle fibers are recruited.

4. Tension Production: The tension produced by a skeletal muscle is directly related to the number of motor units activated. When more motor units are recruited, more muscle fibers contract simultaneously, resulting in a greater overall force or tension generated by the muscle.

Therefore, the number of motor units activated is proportional to the amount of tension produced by a skeletal muscle. By recruiting more motor units, the muscle can generate greater force to perform various movements and tasks. Therefore, the correct option is B).
