What is cellular respiration?Cellular respiration is a succession of chemical reactions that break down glucose to produce ATP, which can then be used as energy to power a variety of reactions throughout the body.
Cellular respiration consists of three major steps: glycolysis, the citric acid cycle, and oxidative phosphorylation.
It is mirror image of photosynthesis, its chemical reaction is:
[tex]C_{6} H_{12}O_{6} + 6 O_{2}--------- > 6CO_{2}+6O_{2}[/tex]
Thus, the correct option is C.

Which part of the body contains enzymes that break down starch into simple sugars? A.mouth B.brain C.stomach D.liver
The part of the body that contains enzymes that break down starch into simple sugars is the mouth (option A).
What is digestion?Digestion is the process whereby ingested food is converted into substances that can be utilized by the body.
Digestion involves the breakdown of large molecules of chemical substances in food into simpler molecules that can be absorbed.
Enzymes are responsible for the chemical degradation of food substances. A specific enzyme in charge of breaking down starch is called amylase and it is present in the saliva of the mouth.
Therefore, the part of the body that contains enzymes that break down starch into simple sugars is the mouth

All of the following are evidence for the big bang except: A. Cosmic background radiation B. Almost all galaxies are red-shifted C. The sound from the bang echoes though the universe D. The universe is expanding
Answer: C. The sound from the bang echoes though the universe
Explanation:
Cosmic background radiation proves the big bang because it shows that as a result of the big bang, the early universe was really hot but cooled as it expanded. Cosmic background radiation is the result of that earlier heat.
Galaxies being red-shifted means that the space between galaxies is increasing which means that the universe is expanding which provides evidence for a big bang because particles move away the single point they are concentrated in.
There was no actual bang from the big bang and sound cannot echo through space so c is incorrect.

The frequency of the pulse is 4.6×[tex]10^4[/tex], when the wavelength of the sonar pulse is 3.2cm. and has a speed of 1,500 m/s in water.
What do you mean by Sonar?The sonar may be defined as a device that is used to find the distance, direction, and speed of underwater objects like water hills, valleys, icebergs, submarines, sunken ships, etc.
The universal wave equation states that the velocity of a wave is equal to the products of its wavelength and frequency.
v = λf
∴ f = v/λ
1500/0.032 = 46,875 Hz.
f = 4.6×[tex]10^4[/tex] Hz.
Therefore, the frequency of the pulse is 4.6×[tex]10^4[/tex], when the wavelength of the sonar pulse is 3.2cm. and has a speed of 1,500 m/s in water.

How can a pure white mouse help determine the genotype of a black mouse? (Hint: We cannot see genotype but we can see differences in the phenotype of their offspring).
Answer:
A white mouse is purely recessive, and will produce black offspring if the other mouse contributes a black gene.
Explanation:
If Bb then the offspring will be 50% Bb and 50% bb. This is called a test cross, where we use a recessive to determine the genotype of a dominant phenotype.
A forest fire destroys an area. A small population of trees and a large population of birds are both affected. Which type
of limiting factor causes this?
O density dependent
O density independent
O population dependent
O population independent
Answer:
Density independent is the correct answer
The type of limiting factor that causes this scenario are density-independent factors, which is Option B, because they affect populations regardless of their size or density.
What are density-independent factors?Density-independent factors are environmental factors that affect populations regardless of their size or density. These factors can include natural disasters such as forest fires, floods, hurricanes, droughts, and other extreme weather events. Other examples of density-independent factors include habitat destruction, pollution, and climate change. In the scenario described, a forest fire destroyed an area, which can lead to the decline of both tree and bird populations. The fire could kill the trees and destroy their habitats, making it difficult for the surviving trees to grow or reproduce.
Hence, the type of limiting factor that causes this scenario are density-independent factors, which is Option B, because they affect populations regardless of their size or density.

what formed the alps mountains
Answer:
The Alps arose as a result of the collision of the African and European tectonic plates, in which the western part of the Tethys Ocean, that was formerly in between these continents, disappeared.
Answer:
The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn.

Which of the following most accurately describes most scientists' current understanding of the evolution of humans?
A: Humans have not evolved.
B: Humans, chimpanzees, and other primates share a common ancestor.
C: Gorillas evolved from humans and chimpanzees.
D. Humans evolved from gorillas and other primates.
Answer:
B: Humans, chimpanzees, and other primates share a common ancestor.
Explanation:
According to the theory of evolution, organisms of a particular species change in their characteristics over several generations because of the process of natural selection. The idea of evolution derives from the fact that all species are related and gradually change over time.
Species which are somewhat related all share a common ancestor. Hence, humans, chimpanzees, and other primates all share a common ancestor.
