1. Basaltic magma is the hottest type of magma. Magma is the hot lava that comes from the eruption of volcanos, and its made of the liquid minerals that are found in the matle, the Earth's second layer after the crust. Basalt is one of the mineral that it is possible to find, and it happens to be one the hottest tupe of magma.

2. Two of the processes that move tectonic plates over the surface of the Earth are ridge push and slab pull. The Earth is not a static object. it has its own balance and equilibrium and the crust upon which we are is always changing and moving. two of the processes that are involved in the destruction of old crust and making of new one are ridge push and slab pull.

3. The longest continuous mountain ranges on Earth is located in the Western portion of the United States. While it is true that it is possible to find longer mountain ranges all around the world, the one locate in the western portion of the usa is the longest continuous, menaning there is no breaking from one mountain to the other.
The vaccine wears out over time?
The flu virus changes every year <----?
The body eliminates the vaccine
Answer:
The correct answer would be the third option.
Vaccination refers to the administration of weekend or attenuated microorganism or antigen in the body. It helps in developing adaptive immunity in the body.
Thus, vaccine neither wears out with time nor body eliminates the vaccine.
However, the flu virus changes every year due to the short life cycle. Consequently, the memory B cells cannot recognize changed virus due to which the body loses its immunity against the virus.
This is why doctors recommend that people should get flu shot each new flu season.
-mouth
-stomach
-esophagus
-pharynx
-small intestine
Answer: The correct answer is Mouth, Pharynx, Esophagus, Stomach, and Small intestine.
Alimentary canal is also known as digestive tract. It represents a pathway through which food is first taken in, then allowed to digest and finally the undigested food in released through anus.
From the given options, the structures included in the alimentary canal are (in the order)- Mouth- Pharynx- Esophagus- Stomach- Small intestine.
Mouth is the structure that ingests the food. Digestion begins in the mouth itself. It starts the digestion of carbohydrates through salivary amylase enzyme.
Pharynx is a muscular flap that aids the movement of food in the esophgus, which helps in the swallowing through peristaltic movements.
Stomach lies after esophagus. Protein digestion takes place in stomach.
Small intestine is a coiled tubular structure where complete digestion of food takes place. It is also the site of absorption of nutrients.
Answer:
A major problem in using geothermal power is corrosion.
(B) Protein-coding genes and noncoding DNA make up about the same amount of the human genome.
(C) Protein-coding genes make up far more of the human genome than noncoding DNA.
(D) Noncoding DNA has not been found in humans.
Answer:
(A) Protein-coding genes make up far less of the human genome than noncoding DNA.
Explanation:
The human genome contains both protein-coding and non-coding sequences. However, the non-coding sequences make most of the human genome as they account for as much as 98.5% of the total human genome. The non-coding part of the human genome serves other important functions such as promoter, enhancers, silencers for gene expression.
An only small part of the human genome serves as protein-coding genes and make exons.
