The correct answer is: There are 20 primary teeth, and by 24 months of age most children have all 20.
Primary teeth also known as deciduous teeth, milk teeth, are the first set of temporary teeth in the growth development of humans. They develop during the embryonic stage of development, become visible in the mouth during infancy (erupt) and usually get replaced by permanent teeth around age six (the first tooth). The primary teeth consist of 4 central incisors (one in each quadrant), 4 lateral incisors, 4 canines, 4 first molars, and 4 secondary molars.
For this question, the correct answer is the flagellum. The flagellum (plural; flagella) is a whip-like or thread-like structure that propels the cell for locomotion. There is another way that a prokaryote can move, with the use of another organelle that is described as short projections called cilia.
<span>The two strands of DNA are complementary. That is, there are four bases and each base in one strand interacts with only one base in the other strand. If you know all the bases in one strand you will be able to figure out all the bases in the other strand. I</span><span>f you are given a strand with the sequence ATTCAG, you know the strand it interacts with has to be TAAGTC. F</span><span>or example, A interacts only with T and C interacts only with G.</span>
Answer:
advancements in spy satellite technology
improved technology for sending living things into orbit
creation of a landing module that could fly back to the ship in orbit
Explanation:
With the end of World War II, the United States and Soviet Union ceased to be allies and began to dispute the political and economic influence in the world. They began to confront each other indirectly in peripheral territories, but also in the field of culture, sports and technology. However, they never directly confronted each other in any military conflict, so this period was called the Cold War.
One of the most visible faces of this dispute was the Space Race. This consisted of the development of vehicles capable of flying over Earth's orbit and perhaps going beyond space. Likewise, it was thought of building a shield that would protect each nation from the missile of the enemy country. For studies and technological development, the governments of both countries recruited Germany's best scientists and engineers, who were unemployed after the 1939-1945 conflict.
The result of this was the creation of several technological advances, among them:
advancements in spy satellite technology
improved technology for sending living things into orbit
creation of a landing module that could fly back to the ship in orbit
Answer:
Stimuli
Explanation:
A thing or event that evokes a specific functional reaction in an organ or tissue is called stimuli. When we touch something, our brain knows that it's touching something due to stimuli.
