What is an advantageous trait that becomes more common in a population?

What is an advantageous trait that becomes more common in a population?

Natural selection is a process that causes heritable traits that are helpful for survival and reproduction to become more common, and harmful traits to become more rare. This occurs because organisms with advantageous traits pass on more copies of these heritable traits to the next generation.

Why are advantageous traits more likely to be passed onto offspring?

Q. Why are advantageous traits more likely to be passed onto offspring? Because they are more likely to survive and reproduce. Because they come from dominant alleles.

Why is genetic variation an advantage for a population?

Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.

Why do traits in populations change over time?

Evolution is a process that results in changes in the genetic material of a population over time. Evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species. The study of evolution can be performed on different scales.

Which term best describes a change in the allele frequencies in a population?

Microevolution, or evolution on a small scale, is defined as a change in the frequency of gene variants, alleles, in a population over generations. The field of biology that studies allele frequencies in populations and how they change over time is called population genetics.

Which conditions are required for natural selection select three options?

The essence of Darwin’s theory is that natural selection will occur if three conditions are met. These conditions, highlighted in bold above, are a struggle for existence, variation and inheritance. These are said to be the necessary and sufficient conditions for natural selection to occur.

How is natural selection different from artificial selection?

The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. For this reason selective breeding is sometimes called artificial selection.

Which of the following structures can perform all the activities required for life?

cells are considered the basic units of life because a cell is the level at which the properties of life emerge. In other words, a cell is the lowest level of structure that can perform all activities required for life.

What name is given to a proposed explanation for a set of observations?

Hypothesis

What does adaptation mean in biological context?

In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. Organisms can adapt to an environment in different ways. They can adapt biologically, meaning they alter body functions.

What is the name given to the reaction that breaks peptide bonds?

hydrolysis

What is the most likely outcome for a person who produces insufficient lactase?

12.3. Lactose intolerance, also called lactase deficiency, is due to an insufficient level of lactase, which hydrolyzes lactose into glucose and galactose. Therefore, ingestion of milk and dairy products results in bloating, abdominal cramps, diarrhea, and related symptoms.

What is a protein’s function dependent on?

A protein’s overall function is dependent on the shape of it. This is determined by four structural levels. The primary structure of an enzyme is simply the sequence of amino acids. Wikipedia. The secondary structure represents how the peptide folds and twists on itself due to interactions between the amino acids.

How many monomers are in a protein?

Usually about 20 types of amino acid monomers are used to produce proteins.
