Answer:
C
Explanation:
The exerpt states that movements in the Earth's crust (unbalance) causes Earthquakes. When it's balanced, there is no plate movement.
Answer: c
Explanation: if there is no plate movement that means that there is a balanced force there is nothing that is disrupting it. but if there's an earthquake in that means that there are unbalanced forces in that they cause an earthquake. a force is balanced if the two individual forces are of equal magnitude and of the opposite direction. And an object is said to be acted upon by an unbalanced force when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction.

which of the following characteristics is true about an organism whose remains formed a good index fossil.
a.) it must be unique orgsnism
b.) it must be an organism that lived all around the world
c.) it must be an organism that lived for a very short time period
d.) all of these characters are important fo an index fossil
Answer:
d.) all of these characters are important fo an index fossil
Explanation:
Organisms have the characteristics to die and their remains form fossils. A fossil is a preserved remain of a previously living organism. Index fossils are fossils used to tell us more about a particular period. However, before the fossil remains of an organism can be used for this purpose, it must have specific characteristics including the following:
- It must be a unique/distinct species
- It must be geographically abundant
- It must live only a short period of time
Based on these above characteristics of a good index fossil, an organism whose remains must form a good index fossil must possess ALL THE MENTIONED CHARACTERISTICS MENTIONED IN THE OPTIONS.
Answer:
d
Explanation:
Index fossils have to be unique and abundant to be easily identified, abundant means it must be around the world. Index fossils usually live for a short period of time. So D is the correct answer.

Read the excerpt from "Bone Detective," by Lorraine Jean Hopping. While the dentist worked on the tiger’s teeth, Diane made an alginate impression of one of its huge paws. Then, the dentist used two cupped hands to pull the tongue out of the big cat’s mouth. The heavily muscled organ was almost as long as her foot. With the dentist still holding the tiger tongue in both hands, Diane quickly went to work. The pink surface was rough, like sandpaper, but floppy and wet. She coated the top with alginate and waited for it to set. Her 15 minutes were almost up. The tiger, so calm and soft, would soon wake up and be dangerous again. Slowly and carefully, Diane peeled off the soft impression to avoid tearing it. Based on this excerpt, what is the author’s attitude toward Diane France? The author feels Diane is rough and impatient in her work with the tiger. The author feels Diane is skillful and careful in her work with the tiger. The author feels Diane is anxious and distracted in her work with the tiger. The author feels Diane is light-hearted and humorous in her work with the tiger.

A marathon runner completed a race of 26.2 miles in 3 hours and 15 minutes. What was his average speed throughout the race?
a) 7.5
b) 8.1
c) 8.7
d) 10
Answer:
b
Explanation:
The average speed of an object is the sum of the distance traveled by the object relative to the total time taken to cover the distance. In other words,
Average speed = total distance traveled/total time taken
In this case, the total distance traveled by the runner = 26.2 miles while the total time taken = 3 hours and 15 minutes
60 minutes = 1 hour
15 minutes = 0.25 hours, hence
3 hours 15 minutes = 3.25 hours
Average speed = 26.2/3.25
= 8.0615 miles/hour
= 8.1 miles/hour
The correct option is b.

how does the structure of fructose compare to the structure of glucose
Answer:
Glucose is an aldose and fructose is a ketose sugar.
Explanation:
They are isomers and they are both ketose sugars that are important building blocks for other sugars.
Glucose is an aldose and fructose is a ketose sugar.
what are the difference between glucose and fructose ?glucose is a monosaccharide present in all major carbohydrates like starch, table sugar etc. It is the primary and preferred energy source of the body. Starch contains glucose.
It is also called as blood sugar or grape sugar which is a six-membered ring, form pyranose ring structure, is an aldohexose.
fructose is a monosaccharide, present in vegetables and fruits where The glycemic index is lower in fructose when compared to glucose.
The binding of fructose to protein in cell is seven times faster than glucose.
fructose are called as fruit sugar or D- fructose. Its functional group is the ketone, metabolized mainly in the liver. It is not found in starch.

A. photosynthesis and nitrate absorption
B. cellular respiration and the citric acid cycle
C. photosynthesis and dehydration synthesis
D. glycolysis and nitrate absorption
Answer:
1. ATP
Explanation:
Cellular respiration may be defined as the chemical process of breakdown of food in the cell with the liberation of energy in the form of ATP.
Photosynthesis is a chemical process through which green plants most photosynthetic algae synthesize their own food in the form of glucose. While nitrate absorption is the process through which nitrogen in the soil is significantly absorbed by the root of plants in form of nitrates.
Fermentation is initiated with the process of glycolysis, but it does not involve the upcoming two stages of aerobic cellular respiration such as the Krebs cycle and oxidative phosphorylation.
Therefore, each of the above questions is well described above.

If a father has type A blood and the mother has Type AB blood, they would NOT have a child with which of the following blood types?
AB
A
B
O
Answer:
If a father has type A blood and the mother has type AB blood, they cannot have a child with blood type O, although depending on the father's genotype, they may not have children with a B blood type either.
Explanation:
Blood type is determined by the presence or absence of surface antigens A and B, which is genetically determined and establishes the pattern of inheritance.
Alleles that define the presence of antigens A and B are co-dominant, while the absence of antigens - as in blood type O - is a recessive trait.
Type A contains antigen A and its genotype can be A|A or A|O. Type B contains the B antigen, whose genotype can be B|B or B|O. Blood type AB contains both antigens and a single genotypic expression A|B Type O blood lacks surface antigens, with genotype O|O.The father with blood type A can have two genotypes, A|A or A|O, which raises 2 possible scenarios:
1. Father A|O with mother A|B
Alleles A O
A A|A A|O
B A|B B|O
In this case there is no chance of having a child with blood type O, 50% chance of having children with blood type A, 25% B and 25% AB.
2. Father A|A with mother A|B
Alleles A A
A A|A A|A
B A|B A|B
50% chance of having a child with blood type A and 50% with blood type AB. In this case there is no chance of having children with blood type O or B.

Which career combines DNA technology and forensics? pharmaceuticals paternity testing environmental studies genetics
Answer:
B. Paternity
Explanation:
Edge 2020
The career that combines DNA technology and forensics is paternity testing. The correct option is B.
What is paternity testing?DNA testing examines an individual's DNA banding patterns to determine the identity or mutations of a specific gene.
Paternity testing is a type of DNA testing that is used to determine paternity and the true nature of a relationship.
The lab compares tissue samples from the mother, the child, and the man to determine what unique characteristics known as genetic markers the child shares with the mother and the man who may be the father.
The chromosomes that determine the gender of the baby (X and Y chromosomes). The mother's egg typically contributes an X chromosome, while the father's sperm contributes either an X or a Y chromosome.
These tests are extremely accurate in determining whether a man is the biological father of a child.
Thus, the correct option is B.
