Explain why the size of your muscles is the is partly an acquired trait and partly dependent on DNA

2 answers:

8 0

Your DNA determines how many muscle fibers a person is born with. This number never changes cause one can't make more muscle fibers during their lifetime. With more muscle fibers, one has the potential to be stronger.
It is an acquired trait because you could train your muscles to become bigger. When you train, for example resistance training, your muscle produces more myofilaments which increases their diameter. This is why you develop large muscles when you train.

Hope this helped!

Answer:

The size of the muscle is partly dependent on the DNA and exercise.

This is because DNA traits is actually responsible for how a muscle formed in the body. This trait is usually gotten from the parents of the offspring.

In the same vein, exercises can also be responsible for the size of an individual’s muscle. Exercises help in the expansion and building of muscle tissues which makes it bigger.

Alchen [17]

This movement from a high concentration area to a low concentration are is called Active transport.

<h3>Active Transport</h3>

Active transport by definition is a process that is characterized by the movement of molecules against a concentration gradient. Additionally, this process requires energy.

As in the question above, glucose molecules have to be moved across the gut lumen of higher glucose concentration to the intestinal cells of relatively low level of glucose.

Describe the factors that influence an individuals phenotype

atroni [7]

Answer:

Physiology, behavior and morphology are considered as phenotype of an individual as these attributes can be observed. Example of phenotypes include wing length, hair color, skin color and height.

<u>There are basically two factors that influence the phenotype:</u>

<u>(1) Genotype or Genetic information of the individual:</u> Some of the phenotypes such as height and skin color are transmitted genetically from generation to generation. Genetic information is the transfer of genes that carry some of the specific genetic information and pass it to another generation which is visible in their phenotype.

(2)<u> Environmental influence:</u> As the phenotype attributes are variable so they are highly influenced by the environment or surrounding they are living. Environmental condition such as temperature, diet, humidity, oxygen levels, and the presence of mutagens affects the phenotype of an individual.

Hence, Genotype and environmental factors influence an individuals phenotype.
