The question is incomplete, the complete question is;
A ray of light travelling in medium 1 strikes and travels into another transparent medium, medium 2. If the speed of light is greater in medium 1, the ray will ............ *
refract away from the normal.
undergo total internal reflection.
refract towards the normal.
have an angle of incidence smaller than the angle of refraction.
Answer:
refract towards the normal.
Explanation:
Refraction refers to the bending of light waves or change in the direction of light waves as a result of change in the speed of light at the boundary between two media.
Whether the rays bend towards or away from the normal depends on the density of the both media. When light travels from medium 1 to medium 2 and medium 1 is less dense than medium 2(shown by a greater speed of light in medium 1 than medium 2) then the ray of light refract towards the normal and vice versa.

Why is mitosis necessary during the development of a human?
Answer:
Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.

For example, plasma membrane proteins carry out functions as diverse as ferrying nutrients across the plasma membrane, receiving chemical signals from outside the cell, translating chemical signals into intracellular action, and sometimes anchoring the cell in a particular location.
Answer:
All cells have plasma membranes. Can molecules enter and leave the cell? Yes. The plasma membrane (also called the cell membrane), is a lipid barrier where molecule organelles live. The golgi ( a cell organelle) helps move the proteins across the plasma membarane. Proteins cannot move through the plasma membrane barrier by themselves because they are not small enough like water.

what is a carbon pool and give some examples of these pools
NEED HELP ASAP ❗️❗️❗️
Answer:
Carbon pools are reservoirs of carbon that have the capacity to both take in and release carbon.There are four very broad global carbon pools which encompass many complex systems which will be discussed on this page. Each of these pools exchange carbon with one another, known as carbon fluxes, comprising what is known as the global carbon cycle.
Explanation:
the Terrestrial ecosystems is a carbon pool and The atmosphere is one to also the ocean really hope this helps

Which of the following would MOST LIKELY result in decreasing carbon dioxide levels in a lake?
A) an increase in the amount of precipitation
B) a decrease in competition among producers
C) an increase in the number of fish caught from the lake
D) a decrease in the amount of sedimentation entering the lake
Answer: C: an increase in the number of fish caught from the lake
Explanation:
An increase in the number of fish caught from the lake would most likely result in decreasing carbon dioxide levels in the lake. Therefore, option C is correct.
What are the effects of carbon dioxide in a lake?Carbon dioxide can have both direct and indirect effects on a lake's ecosystem. Here are some of the effects:
Acidification: When carbon dioxide dissolves in water, it forms carbonic acid, which can lower the pH of the water.
Oxygen depletion: If carbon dioxide levels are too high, it can lead to oxygen depletion in the water.
Algal blooms: High levels of carbon dioxide can also stimulate the growth of algae in the water. This can result in algal blooms, which can have negative effects on the lake ecosystem, such as oxygen depletion, fish kills, and changes in water clarity.
Thus, an increase in the number of fish caught from the lake would most likely result in decreasing carbon dioxide levels in the lake. Therefore, option C is correct.

4. Many of your body’s responses operate off of either negative or positive feedback loops. When you are cold, you shiver. Explain why that happens.
Answer:
The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose. If these values get too high or low, you can end up getting very sick.
Homeostasis is maintained at many levels, not just the level of the whole body as it is for temperature. For instance, the stomach maintains a pH that's different from that of surrounding organs, and each individual cell maintains ion concentrations different from those of the surrounding fluid. Maintaining homeostasis at each level is key to maintaining the body's overall function.
Explanation:
shivering burns fat to help keep one warm
Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.
