Glycogen provides long-term energy storage.
Glycogen is an example of a carbohydrate which is a polysaccharide that acts as a long-term energy storage compound in animals.
<h2>Further Explanation
</h2>
- Living organisms require energy in order to undertake their daily activities such as growth and development, locomotion, gaseous exchange, etc. To do so they obtain nutrients for short-term and long-term energy source.
- Carbohydrates are the major energy source for living organisms, however, living organisms may use other sources of energy such as proteins or fats when carbohydrates is out of stock or not available.
Energy source in animals
- Animals use simple carbohydrates such as glucose obtained from diet for short-term energy sources.
- These simple carbohydrates may also be stored for future use in the form of glycogen, which makes glycogen a long-term energy source, to be used when need arises.
- When glucose levels are low in the body hormones in the body trigger the breakdown of glycogen to glucose.
- Other sources of energy such as proteins and fats are used when carbohydrates storage is depleted, for example during starvation.
Energy source in plants
- In plants, on the other hand, simple carbohydrates are similarly used as a short term source of energy. Additionally, simple molecules such as glucose are stored in the form of starch for long-term source of energy for the plants.
<em><u>Why other Choices are incorrect</u></em>:
<h3>Glucagon </h3>
- Glucagon is the hormone that increases the blood glucose level to avoid it from dropping below optimum level.
- The hormone acts on the liver to stimulate the breakdown of glycogen to glucose, a process called glycogenolysis, and the glucose is released to the blood stream.
<h3>
Glucose
</h3>
- Glucose is a simple carbohydrate classified as monosaccharides. It acts as the short term source of energy in both plants and animals.
- It is readily broken down during the process of cellular respiration to yield energy in the form of ATP, which is then used to drive cellular processes.
<h3>Cellulose
</h3>
- Cellulose is an example of a complex carbohydrates known as polysaccharides.
- It is found in plants cells lining the cell wall of all plant cells which is one of the key distinguishing feature between plant cells and animal cells.

Answer:
Paleontologists may start their investigations by reading articles from the fossil record found in a specific region
Explanation:
Dina may examine the paleontological evidence that includes the study of the fossil record found in her hometown (or closest regions). Moreover, Dina may read research articles on the phylogeography of the species in this area, this information may also help to understand the past climatic conditions
Answer:
Error: The Methionine at the end of the chain
Explanation:
Hello! Let's solve this!
The start codon is AUG, this codon encodes Methionine. Therefore all proteins will start the amino acid sequence with Methionine.
In this case, the student placed the Methionine at the end of the chain, so that is the mistake. Methionine goes to the beginning of the chain.
Parallel
In a parallel arrangement, the length of the fascicles runs parallel to the long axis of the muscle. Such muscles are either straplike like the sartorius muscle of the thigh, or spindle shaped with an extended belly, like the biceps brachii muscle of the arm. However, some scientists classify spindle-shaped muscles into a separate class asfusiform muscles.
Pennate
in a pennate pattern, the fascicles are short and they attach obliquely to a central tendon that runs the length of the muscle. Pennate muscles come in three forms:
<span><span>Unipennate, in which the fascicles insert into only one side of the tendon, as in the extensor digitorum longus muscle of the leg. </span><span>Bipennate, in which the fascicles insert into the tendon from opposite sides so the muscle “grain” resembles a feather.
The rectus femoris of the thigh is bipennate. </span><span>Multipennate, which looks like many feathers side by side, with all their quills inserted into one large tendon. The deltoid muscle, which forms the roundness of the shoulder is multipennate.</span></span>
Lactase refers to an enzyme that can dissociate lactose sugar into glucose and galactose. This enzyme plays an important role in the digestion of milk that comprises high lactose sugar. In case, if a mutation occurs in the gene codon of lactase, then two possibilities can take place. These are as follows:
1. Loss of mutation: In this case, the person becomes lactose intolerant because of mutation in lactase gene codon. Due to this, there is low mRNA expression and thus low production of the enzyme lactase. This is also known as lactase non-persistent phenotype.
2. Gain in mutation: In this case, the person gain an increase in mRNA expression of the lactase gene, thus more production of lactase takes place than usual. This kind of individual exhibits lactase persistent phenotype.
