Answer:
There are several answers to this question: The appearance of a novel phenotype resulting from a substitution of a single base pair might be due to:___. These possibilities are:
1. A change in the sequence of amino acids. It must be remembered that proteins are the ones that carry out the instructions present in genes, therefore, a change in the sequence may show also a change in a base pair, and a change in what is expressed phenotypically.
2. Change in the amount of protein that is transcribed. Again proteins are the ones that carry out the instructions from genetic material. A change in DNA will show in how not just amino acids will be arranged, but also the structure, and amount of protein transcribed, and also the types. This will alter the phenotypical expression.
3. Change in the developmental time and/or location at which a gene is expressed. Time and also the placement of the base pairs in the genetic sequence can alter how these are expressed when they are translated into RNA.
4. Alteration in a gene that codes for a non-translated RNA. It is RNA the one that will transfer information from genes in DNA and the final product, which are proteins. However, when DNA has a change in the genes that will be translated into RNA, the process may not be carried out, and if RNA is not produced, then neither will proteins. The absence of a specific sequence in RNA will also affect the production of protein and thus a phenotypical expression may, or may not, happen.
E= unattached earlobes
e= attached earlobes
Heterozygous means a dominant and non dominant trait so both parents have Ee. By using a punnet square you can determine the genotype of their offspring will be:
EE-25% chance
Ee-50%chance
ee-25% chance
Explanation:
Models are important in science because a model is a representation of an idea or an object or systems that could be used to describe something that cannot be experienced directly
The structural level in which the muscle produces the contraction is known as the muscle fiber.
<h3>What is a muscle fiber?</h3>
A muscle fiber is a single muscular cell that is able to contract by using specialized proteins such as filaments of myosin and actin.
This unit (muscle fiber) is able to contract both in vivo and in vitro by establishing suitable environmental conditions (e.g., proper calcium levels).
In conclusion, the structural level in which the muscle contracts is the muscle fiber.

Answer:
True (although question is not clear enough)
Explanation:
Adaptive radiation occurs when <u>organisms evolve from the same ancestor. This process takes place as a result of environmental changes or when they are introduced to or colonize a new environment.</u> These changes become challenges that force these individuals to adapt to these new conditions.
Therefore, <u>this results into a faster evolution that creates different new forms</u> that possess a diversity of variations adapted to their new feeding habits, environment, and behavioral needs.
<em>One of the most famous examples of adaptive radiation is the formation of new forms of Galapagos finches.</em> These striking finches, which arose from a common ancestor, evolved different beak sizes and shapes that were especially adapted to different types of food. As different as they may appear, they are closely related!
