Can RNA undergo a natural selection and cause evolution or change?
no
Are new alleles made by natural selection?
No - natural selection does not create new alleles. Variation in alleles needs to exist in the population in order for natural selection to occur. Natural selection will involve the change in allele frequencies over time, but it does not create new alleles. New alleles are the result of mutations.
If a population consists only of individuals cloned from a single organism then a Lamarck was right about species change for that populaiton b natural selection would not occur in that population?
Neither. Lamarckian evolution does not take place at all; almost all of his concepts are now known to be incorrect. The population will still undergo mutation, and natural selection for beneficial mutations and against harmful ones will still occur.
What are the different ways in which individuals with a particular trait may increase in a population?
different ways in which individuals with particular trait may increase are -if that particular trait provides them with some sort of support to undergo the circumstances they are found in, we can also call it natural selection -or due to any genetic drift, that is a natural calamity, also called a chance selection
Explain how the structure and function of DNA enable species to change over time through natural selection.?
The structure of DNA allows for genetic variation through mutations, which introduce new traits into a population. Natural selection acts on these variations, favoring traits that increase an organism's fitness for its environment. Over time, these advantageous traits can accumulate in a population, leading to species adaptations and evolution.
Can RNA undergo natural selection and evolve?
If RNA is used as a genetic molecule, passing traits from parent to offspring, then it is subject to natural selection. This only happens in a number of viruses and very few bacteria, though: most organisms use DNA as their genetic molecule.
Do dogs undergo artificial selection in the process of breeding?
Yes, dogs undergo artificial selection in the process of breeding, where humans selectively breed dogs with desired traits to create specific breeds.
The smallest biological until that can evolve over time is?
The smallest biological unit that can evolve over time is an individual organism, typically a unicellular organism like bacteria or archaea. These organisms can undergo genetic mutations and natural selection, leading to the evolution of their populations over generations.
What are not individual organisms change or evolve over many generations?
Populations undergo changes in gene frequencies through processes like natural selection, genetic drift, and gene flow, which contribute to the evolution of a species over many generations. This can lead to the emergence of new traits or the adaptation to changing environments within a population.
The only organization level of life that can become genetically adapted to its environment is the?
The only organization level of life that can become genetically adapted to its environment is the population. Populations consist of groups of individuals of the same species that live in a particular area and can undergo natural selection over generations. This process leads to genetic changes within the population, allowing it to better survive and reproduce in its specific environment. Individual organisms may adapt behaviorally or physiologically, but true genetic adaptation occurs at the population level.
Is the selection process for TSA PreCheck random?
No, the selection process for TSA PreCheck is not random. Travelers must apply and undergo a background check to be eligible for TSA PreCheck.
Is evolution the same as growth and metamorphosis?
Evolution refers to the change in genetic characteristics of a population over generations, involving mechanisms such as natural selection. Growth typically refers to an increase in size or mass of an individual organism, often controlled by hormones and environmental factors. Metamorphosis is a process some organisms undergo, involving distinct stages with different body forms, such as the transformation from a caterpillar to a butterfly.
