Answer:

10. chlorophyll

11. There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle.

12. Nutrition is necessary for the growth of new cells and the replacement or repair of worn-out cells. Nutrition gives energy for different metabolic processes in the body. Nutrition is required to produce resistance against different diseases.

13. trypsin

14. salivary amylase

15. Hydrochloric acid helps your body to break down, digest, and absorb nutrients such as protein. The hydrochloric acid found in the stomach facilitates digestion by disintegrating complex large food molecules into simpler molecules. The acid activates the pepsinogen enzyme required to digest proteins.

16. Saliva, the watery liquid produced by glands located under the tongue, is an essential component of the digestive process. Saliva is 98% water, so it moistens the mouth and helps compact food into softened particles for easier swallowing.

17. Digestive enzymes play a key role in breaking down the food you eat. These proteins speed up chemical reactions that turn nutrients into substances that your digestive tract can absorb. Your saliva has digestive enzymes in it. Some of your organs, including your pancreas, gallbladder, and liver, also release them.

18. small intestine

19. heterotrophic

A museum curator collects fossils from two different periods. He has 400 from one period and 204 from a later period. He plans t

matrenka [14]

Answer:

Explanation:

Number of fossils collected over period 1:

400

Number of fossils collected at a later period :

204

For each display case to have the same number of fossils ; the greatest number of fossils possible per case:

Obtain the greatest common factor of both 400 and 204

400 = 1, 2, 4, 5, 8, 10, 25, 40, 50, 80, 100, 200, 400

204 = 1, 2, 3, 4, 6, 12, 17, 34, 51, 102

Hence, the greatest common factor (400 and 204) is 4

Hence, the greatest Number of Fossil possible per case = 4

What happens when sunlight hits the atmosphere

ser-zykov [4K]

Once energy from the Sun gets to Earth, several things can happen to it: Energy can be scattered or absorbed by aerosols in the atmosphere. ... Light colored surfaces are more likely to reflect sunlight, while dark surfaces typically absorb the energy, warming the planet.

Describe the strength of the magnetic field at points a b and c in the image below. Explain your answers in the terms of magneti

Nastasia [14]

The magnetic fields are strongest at point A and weakest at point C. The magnetic field lines can be used to indicate the strength of a magnet or magnetic field. The closer together the magnetic field lines the stronger the magnetic field.

Explanation:

The magnetic field line also shows the direction of the magnetic field, hence they are also considered vector fields because they have magnitude and direction. They usually have an arrow indicating that the field lines are moving from the north pole to the south pole. The lines also never cross and are always in closed loops.

11. What is speed?

Harrizon [31]

11. In everyday use and in kinematics, the speed of an object is the magnitude of the rate of change of its position with time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.

12. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector. In its simplest form, average velocity is calculated by dividing change in position (Δr) by change in time (Δt).

13. Here we will learn the mathematical relation between the speed, distance and time. The speed of a moving body is the distance travelled by it in unit time. If the distance is in km and time is in hours, then the speed is km/hr. If the distance is in m and the time is in seconds, then the speed is m/sec.

14. Average speed is the distance traveled divided by elapsed time. We have noted that distance traveled can be greater than displacement. So average speed can be greater than average velocity, which is displacement divided by time

15. Both have the same average speed, so neither is the fastest. (Please see the solution in the picture)

16. Acceleration is a vector quantity which is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.
