3. In science, a theory is more like a scientific law than a hypothesis. A theory
explains a set of observations or events. It must be verified multiple times by
many different scientists. One scientist cannot create a theory on his or her own.
a) Look back at your hypothesis from question 2. Could this hypothesis become
a theory if you repeated your experiment 100 different times and got the same
results? Can a theory be created by just one person? (2 points)
Answer:
No
Explanation:
A theory cannot be made by one person, no matter how many times they repeat the experiment. Therefore, you repeating the experinment does not make it a theory. The experinment must be repeated by others and get same result as you to confirm it as theory.

Traits are passed from parents to offspring. These traits are determined by
(1) chromosomes, located on genes, found in the nucleus
(2) genes, located on chromosomes, found in the nucleus
(3) chromosomes, located on genes, found in the ribosomes
(4) genes, located on chromosomes, found in the ribosomes
Answer:
The traits that are transferred from the parents to the offspring during reproduction are determined by genes, located on chromosomes, found in the nucleus.
Explanation:
During reproduction, there is a fusion of;
male gamete
female gamete
This leads to the formation of offspring. There is a transfer of traits from the parents to the offspring.
Hence, the traits that are transferred from the parents to the offspring during reproduction are determined by genes, located on chromosomes, found in the nucleus.
Answer:
(2) genes, located on chromosomes, found in the nucleus
Explanation:
Traits are determined by genes which are located on chromosomes. Chromosomes, on the other hand, are located in the nucleus.

fossil fuels are nonrenewable, so humans must use less to allow them to be replenished naturally. burning fossil fuels also only damages nearby ecosystems.
Answer: b. fossil fuels are nonrenewable, so humans will run out of them eventually. burning fossil fuels also contributes to global climate change by releasing carbon dioxide into the atmosphere.
Explanation:
Fossil fuels are limited and we will run out of them eventually. They cannot be replenished in a single human's lifespan. Fossil fuels contribute to the destruction of ecosystems, but not only that. They release carbon dioxide into the atmosphere that warms the Earth. Therefore, anything other than B. would be incorrect.

A. Point D
B. Point B
C. Point A
D. Point C
Answer:
Point B
Explanation:
Point B is getting the most light and is closet to the surface
Point B is getting the most light and is closet to the surface.
What is Photic zone?The daily cycle of light and dark in the photic zone of the world's oceans is maybe the most potent environmental signal accessible. Russell's suggestion that zooplankton resided in depths with the best light intensity was one of the early reports to propose that light had a major role in vertical migration.
He went on to say that as animals strayed from this zone of ideal light intensity, physiological responses governed by photochemical systems prompted them to come back.
Subsequent reviewers came to the conclusion that there was a lot of (although speculative) evidence that light had a substantial role in controlling fish's vertical migration.
Therefore, Point B is getting the most light and is closet to the surface.

Answer:
6. A. LATITUDE7. C. ANTARCTIC CIRCLE8. D. Topsoil, Subsoil, Parent materialExplanation:
6. Latitude is the measurement of distance north or south of the Equator. It is measured with 180 imaginary lines that form circles around the Earth east-west, parallel to the Equator. These lines are known as parallels
7. These zones are found in the North and South Poles. The South Frigid Zone is located between the Antarctic Circle and the South Pole, and the North Frigid Zone is located between the Arctic Circle and the North Pole.
8. As we know that the first layer of soil is topsoil , the middle layer of soil is subsoil and after the sub soil there is bedrock. Therefore, the correct arrangement of layers is top soil, subsoil, bedrock.

Pls helpthe sun hits the ocean at the equator more directly than at the poles. how does this support the flow of currents in the ocean?
The Sun creates a lot of thermal energy in the atmosphere and the oceans. Currents created as warm equatorial waters move to the north carrying heat. Due to this, the cold polar waters go south, and there get heated.
What is thermal energy?Thermal energy refers to the energy within a system and is responsible for its temperature.
The Sun heats up the air at the equator. This air will move toward the poles and cools down there with time.
In this process, the wind that occurs due to air currents will induce currents at the ocean surface.
The currents at this surface are propagated down deeper due to the differences in the forces on different parts of the water.
Thus, It is the main reason that the sun hits the ocean at the equator more directly than at the poles.

olfactory cells and taste buds are normally stimulated by ________.
Answer:
The answer is substances in solution.
Explanation:
Olfactory cells and taste buds are normally stimulated by substances in solution.
Olfactory cells are normally stimulated by odorants, which are chemical substances that are volatile and capable of being detected by the sense of smell.
Taste buds, on the other hand, are normally stimulated by tastants, which are chemical compounds that can be tasted. Tastants include various molecules such as sweet, sour, bitter, salty, and umami compounds.
Both olfactory cells and taste buds play crucial roles in our perception of smell and taste, respectively, and they are stimulated by specific chemical substances that interact with receptors present in these sensory cells
