b. Alcohol is a depressant, which means it speeds up the nervous system.
c. Before alcohol is metabolized in the body, it is an active brain drug and a cellular toxin.
d. Alcohol is created when grains, fruits, or vegetables are fermented.
Answer : Option B) Alcohol is a depressant, which means it speeds up the nervous system.
Explanation : Alcohol is a nervous system depressant which slows down the central nervous system and peripheral nervous system activities. It is also an active brain drug and a cellular toxin before it is metabolized by the body enzymes.
Alcohol is produced by fermenting grain, fruits or vegetables for several months or years. When packed in cans or bottles, the label which shows the alcohol content is expressed as alcohol percent.
Answer:
B) alcohol is a depressant, which means is speeds up the nervous system
Explanation:
Alcohol is a central nervous system (CNS) depressant psychotropic substance that promotes simultaneous alteration of numerous neuronal pathways, generating various biological and behavioral changes. Is speeds DOWN the nervous system.
The Alcohol intake causes several effects, which appear in 2 distinct phases: a stimulant and a depressant. In the first moments after drinking alcohol, stimulating effects may appear, such as euphoria, disinhibition and loquacity (easier to speak). Over time, depressing effects such as poor motor coordination, uncontrollability, and sleepiness begin to emerge.
Answer:
C: Bicep Curl
Explanation:
A concentric contraction is a contraction where the muscle shortens when contracting. When doing a bicep curl, the bicep shortens when it contracts.
Answer:
Option (1).
Explanation:
Kidney are one of the most important organ of the body that plays an important role in excretion. The kidney contain millions of neurons that acts as the filtration unit of kidney.
Kidneys are the bean shaped organ and present in pair. The kidneys are located at the the back of the muscles on the right and left sides of the body. They are present between the peritoneum and the posterior abdominal wall of the body.
Thus, the correct answer is option (1).
The kidneys are located in the retroperitoneal space, beside the vertebral column between the T12 and L3 vertebrae. The left kidney is positioned more inferiorly than the right kidney due to displacement by the liver. The kidneys are not entirely sheltered by the ribs, and they're not inside the peritoneum.
The true statements are: The kidneys are located on either side of the vertebral column, roughly between the T12 and L3 vertebrae, in a space called the retroperitoneal space which is between the parietal peritoneum and the posterior abdominal wall. Also, the left kidney is more inferior than the right kidney due to slight displacement by the liver. However, the kidneys are not completely protected by the ribs. Only the upper portions of the kidneys are somewhat protected by the eleventh and twelfth ribs. The kidneys are not within the peritoneum but are held to the posterior in a retroperitoneal position by the renal fascia and peritoneum.
