A child pulls a toy across the floor. What is the equal and opposite force for the force of the child pulling forward on the toy as described by Newton's third law? Choose 1 answer: Choose 1 answer: (Choice A) A Ground's normal force pushes up on the child's feet. (Choice B) B Ground's friction pushing on the toy (Choice C) C Child's feet's friction pushing on the ground in the opposite direction (Choice D) D Toy pulls on the child in the opposite direction
Answer:
D. Toy pulls on the child in the opposite direction
Explanation:
Newton third law of motion states that for every action, there is an equal and opposite reaction. This means that whenever an object 1 exerts a force (action force) on another object 2, object 2 exerts a force (reaction force) of equal magnitude but opposite direction on object 1.
According to this question, a child pulls a toy across the floor. Based on Newton third law described above, the toy will pull the child with an opposite force that is equal in magnitude. Hence, the equal and opposite force is: Toy pulls on the child in the opposite direction.

1- why dong you usually get sick from the exact same pathogen twice
2-if a pathogen mutated so it had different antigens, would your memory B and memory T cells recognize it?
please help this is due at 3pm
1: For example, rhinovirus has over 100 different serotypes. Now, the good news is that you can't get ill from the same virus serotype right after getting better, due to the fact that you'll have developed antibodies which help to protect your immune system for a little while.
2:Most children in the United States are now vaccinated against measles virus; before vaccination was widespread, most were naturally exposed to this virus and suffered from an acute, unpleasant, and potentially dangerous viral illness. Whether through vaccination or infection, children exposed to the virus acquire long-term protection from measles. The same is true of many other acute infectious diseases: this state of protection is a consequence of immunological memory.
The basis of immunological memory has been hard to explore experimentally. Although the phenomenon was first recorded by the ancient Greeks and has been exploited routinely in vaccination programs for over 200 years, it is just now becoming clear that memory reflects a persistent population of specialized memory cells that is independent of the continued persistence of the original antigen that induced them. This mechanism of maintaining memory is consistent with the finding that only individuals who were themselves previously exposed to a given infectious agent are immune, and that memory is not dependent on repeated exposure to infection as a result of contacts with other infected individuals. This was established by observations made on remote island populations, where a virus such as measles can cause an epidemic, infecting all people living on the island at that time, after which the virus disappears for many years. On reintroduction from outside the island, the virus does not affect the original population but causes disease in those people born since the first epidemic. This means that immunological memory need not be maintained by repeated exposure to infectious virus
In the Krebs Cycle of cellular respiration, pyruvate is used to make
A.oxygen
b. carbon dioxide
C water
D. More glucose
Answer:
b. carbon dioxide
Explanation:
This metabolic pathway is called the Krebs cycle after the scientist who first discovered it in 1937. The Krebs cycle is further broken down by pyruvic acid, obtained in the glycolysis process. The process proceeds in two stages. The first is the degree of decomposition of the bicarbonate residue.
The Krebs cycle is the main metabolic pathway for the breakdown of organic matter and the production of energy in the form of reduced coenzymes, which will then be incorporated into ATP.
What is the average speed of a soccer ball that travels 34 m in 2s?
Answer:
17 m/s
Explanation:
s=d/t
s=34m/2s
Answer:
34/2 = 17 m/s
Explanation:
Distance Covered: s = 34 m
Time in which distance covered: t = 2 s
----
Average Speed: v = Distance Covered/time taken = s/t
v = 34/2
v = 17 m/s

The earth , the sun , and the seven other planets that are in orbit around the sun are part of the solar system. How does the size of the solar system compare with the size of the milky way galaxy ?
Answer:
Size of milky way galaxy is very large than our solar system.
Explanation:
The size of the solar system is much smaller than the size of the milky way galaxy because our solar system is a part of milky way galaxy. The radius of our solar system is 4.545 billion km while on the other hand, the radius of the milky way galaxy is 52,850 light years which is very very large than the radius of our solar system. Milky way galaxy has 100–400 billion planets while in our solar system has only eight planets.

1. strawberries
2. fish
Explanation:
As per the given scenario, The best source of vitamin C is strawberries, while fish is naturally rich in vitamin B12. The correct option for first blank is B, and for second one is A.
What are vitamins?A vitamin is an organic molecule that is an essential micronutrient that an organism requires in small amounts for proper metabolism function.
Fat-soluble vitamins are stored in the liver, fatty tissue, and muscles of the body. Vitamins A, D, E, and K are the four fat-soluble vitamins.
Water-soluble vitamins do not accumulate in the body. Vitamin C and all of the B vitamins are among the nine water-soluble vitamins.
As per the given scenario, The best source of vitamin C is strawberries, while fish is naturally rich in vitamin B12.
Thus, the correct option for first blank is B, and for second one is A.

After cell division (mitosis) how does the genetic code of the newly
produced cells compare to the code of the parent cell?
Answer:
Chromosomes were first named by cytologists viewing dividing cells through a microscope. The modern definition of a chromosome now includes the function of heredity and the chemical composition. A chromosome is a DNA molecule that carries all or part of the hereditary information of an organism. In eukaryotic cells, the DNA is packaged with proteins in the nucleus, and varies in structure and appearance at different parts of the cell cycle.
Explanation:
Cells reproduce genetically identical copies of themselves by cycles of cell growth and division. The cell cycle diagram on the left shows that a cell division cycle consists of 4 stages:
G1 is the period after cell division, and before the start of DNA replication. Cells grow and monitor their environment to determine whether they should initiate another round of cell division.
S is the period of DNA synthesis, where cells replicate their chromosomes.
G2 is the period between the end of DNA replication and the start of cell division. Cells check to make sure DNA replication has successfully completed, and make any necessary repairs.
M is the actual period of cell division, consisting of prophase, metaphase, anaphase, telophase, and cytokinesis.
