1) An action potential is propagated down the lower motor neuron
2) Calcium levels increase in the cytoplasm of the muscle cell
3) Acetylcholine binds its receptor and causes depolarization
4) Vesicles containing glutamate fuse with the nerve terminal
5) Contraction.
Answer:
4,1,3,2,5
Explanation: Glutamate is the neurotransmitter that excites the motor neurons and produces action potential in motor neurons. Then this action potential travels down towards the axonic terminal where it would cause release of acetylcholine. ACh then binds to postsynaptic membrane causing depolarization of sarcolemma. Calcium ions are released into the sarcoplasm resulting in muscle contraction.
An individual’s behavior characteristics, emotional expression, and intensity that is established from birth is known as temperament.
Answer:
If you are referring to the image below, the answers would be:
Monosaccharides:
- Galactose
- Glucose
- Ribose
- Deoxyribose
- Glyceraldehyde
- Fructose
Disaccharides:
Storage Polysaccharides:
Structural Polysaccharides:
Explanation:
Monosaccharides are simple sugars, typically having 3 to 7 carbons in its structures. Aldoses and ketoses are forms of monosaccharides. If a monosaccharide has a aldehyde, it is an aldose. If a monosaccharide has a ketone, it is a ketose. You also have other forms, depending on te number of carbons. (e.g. Tioses, hexose and pentose)
Disaccharides are two monosaccharides bonded covalently through a glcosidc bond. They form through a condensation reaction, specifically through dehydration synthesis. Thus, the name "di" saccharides.
Polysaccharides are complex carbohydrates that are made up of many monosaccharides. Their functions are mainly storage and make up the structure of tissues.
Storage polysaccharides are polysaccharides that act as food reserves or energy reserves. They are called storage because they are stored away for later use. Starch is a storage polysaccharide that is found in plants and glycogen on the other hand, is found in animals.
Structural polysaccharides help form the structures of cell walls in plants and skeletons in animals. The most common ones are chitin and cellulose.
Answer:
B. preservation of advantageous genetic mutations
Explanation:
The process of natural selection involves the preservation of advantageous genetic mutation in a given population.
Natural selection is one of the key factors that ensures the evolution of organisms.
- Desired traits that are able to survive adverse conditions like disease, food shortage, natural disasters are favored by the process of natural selection.
- Traits that also undergo advantageous genetic mutation in order to get a competitive advantage is also accrued to natural selection.
The membrane bound organelle you refer to is the Lysosome. The lysosome fuses with a vacuole where it digest the contents.
