Label the angle of incidence and the angle of reflection in the Figure below.
In the picture, I have highlighted the angle of incidence blue and the angle of reflection red.
hope this helps :)
Angle of incidence refers to the angle between the incident ray and the normal, while angle of reflection represents the angle between the reflected ray and the normal.
Thus, angle of incidence is the angle formed by the incident ray which is the light beam flowing in and the normal which is a line perpendicular to the surface at the point of incidence. The angle of reflection, denoted by the symbol r, is the angle between the normal and the reflected ray of light (the ray of light that bounces off the surface).
The angle of incidence and angle of reflection are equal, according to the law of reflection. The angle at which light reaches a surface and the angle at which it reflects off of it are identical. This fundamental concept describes how light interacts with surfaces, such as mirrors or smooth objects.

Give an example of how a random mutation in an organism could give it an environmental edge over other members of its species.
Do changes in the environment CAUSE mutations or are they already present in the gene pool of a population? Explain.
Answer: The mutation could cause it to adapt to the environment better, pick up food better, or even become almost totally different to the others because of how different it is. changes in the environment determines which organism lives. Some mutations seem to happen spontaneously without any outside influence. They can occur when mistakes are made during DNA replication or transcription. Other mutations are caused by environmental factors. Anything in the environment that can cause a mutation is known as a mutagen. Mutations can occur during DNA replication if errors are made and not corrected in time. Mutations can also occur as the result of exposure to environmental factors such as smoking, sunlight and radiation. ... Mutations contribute to genetic variation within species.

Explanation:
Stomata are composed of two guard cells. These cells have walls that are thicker on the inner side than on the outer side. This unequal thickening of the paired guard cells causes the stomata to open when they take up water and close when they lose water.
sorry if it's wrong
Answer: C. When the guard cells are full of water, they become stiff and hold the pore open.

Answer:
eukarya
Explanation:
so long as that stands for eukaryotic
fungi is eukaryotic
other 2 are multicellular, and therefore eukaryotic
if u don't like the first explanation, the second one is process of elimination
archaebacteria is a kingdom, so it can't be that, same with plantae.
fungi isn't a bacteria so it can't be that either
only option remaining is eukarya

Explanation:
The Nervous System is one of the first systems to develop during the embryonic period. Why do you think this is?
The process of neurulation, which takes place between weeks three following conception, allows the embryo to form the components that will one day become the nervous system. It's important to regulate body functions.
What is embryonic nervous system?The neural crest gives rise to the development of structures in the periphery. At this stage, the early nervous system resembles nothing more than a straightforward tube. It begins from the front of the embryo and continues all the way around to the back. Beginning at day 25, the anterior end will develop into the brain, while the posterior portion will develop into the spinal cord.
The brain is the organ that is responsible for controlling every function of the body. The brain is connected to the rest of the body through the spinal cord, which travels down the back. It contains nerves that are similar to threads and branch out to every organ and area of the body. Messages are transmitted to and from the brain via this network of nerves, which connects the brain to various regions of the body.

Use the drawing tool to modify the model, showing the direction of prevailing winds in the Northern Hemisphere and convection currents. Label hot and cold air on your convection currents.
Answer:
Image down below will be correct.
Explanation:
The direction of prevailing winds and convection currents in the Northern Hemisphere and how to label them.
What is westerlies?Prevailing winds in the Northern Hemisphere generally blow from west to east due to the Coriolis effect. This means that winds move clockwise around areas of high pressure and counterclockwise around areas of low pressure. The prevailing winds are known as the westerlies.
Convection currents in the Northern Hemisphere are driven by temperature differences between the equator and the poles. Warm air rises at the equator and moves towards the poles, while cold air sinks at the poles and moves towards the equator.
This creates a convection current that moves from the equator to the poles in the upper atmosphere and from the poles to the equator in the lower atmosphere.
To label hot and cold air on your convection currents, you can draw arrows to show the direction of movement and label them accordingly. Hot air rises at the equator and cold air sinks at the poles, so you can label the arrows with "hot" and "cold" respectively.

increased?
4. Describe how the fish population would change if the seal
population decreased.
The killer whales have a tremendous flow of energy as the whale eats and consume more protein and a nutrient-rich diet.
What is a killer whale?1. A killer whale is also called an Orca and a toothed whale. The whale is the largest member of the killer whale specie and has tremendous flow of energy due to they fed on small and large aquatic forms.
2. If the whale is removed from the ecosystem then the food chain will get disturbed and there will large growth of other species of fish will be in abundance.

Answer: the plants get there energy and nutrients from the sun/ sunlight, if the hawks were removed from the ecosystem the rabbits and snakes population would grow higher.
Explanation:
1. Describe the flow
of energy in a
marine food web.
Include at least 5
organisms.
2. Describe how
removing an
organism from a
food web can
impact the entire
ecosystem.
Answer:
1. A food chain is a single pathway connecting a producer with several levels of consumers. In a typical marine food chain, dinoflagellates convert energy from sunlight into food through photosynthesis and store it in their tissues.
2. They would starve and die unless they could move to another habitat. All the other animals in the food web would die too, because their food supplies would have gone. The populations of the consumers would fall as the population of the producer fell.

The flow of energy in a marine food web include the following:
Plankton⇒shrimp⇒ salmon⇒ seals⇒ whales
What is a food web?A food web comprises of food chains which are interconnected and also
explains the flow of energy between organisms in the ecosystem.
In the marine ecosystem, the plankton which are plants are the primary
producers while the whales are the tertiary/quaternary consumers as they
are at the top of the web.
Removing an organism from a food web can impact the entire ecosystem
by reducing the number of organisms and options available for food. It can
increase or decrease the population of organisms which they have direct
