If you use direct sunlight to observe a specimen it will damage your eyes.
A. True
B. False
Answer:True
Explanation: Microscopes often use a mirror to direct available light to the specimen platform, so if you don't have enough light it will be difficult to view your specimen and can cause eye strain.
Microscopes may malfunction if stored or used in a location exposed to direct sunlight. Also, direct sunlight may harm the observer's eye if it enters a microscope through the reflector.
For optical microscopes:
Light from outside is sent to the reflective mirror to illuminate the sample. Direct sunlight must be avoided. ... This inexpensive and readily available lamp, also called an incandescent lamp, is widely used in optical microscopes.
Hope this helps you in some way. Aloha

Scientists must use microscopes to study the cells of living things. Explain why microscopes are necessary to study cells. Then, describe some things microscopes have helped scientists discover about cells
A cell is the smallest unit of life. Most cells are so small that they cannot be viewed with the naked eye. Therefore, scientists must use microscopes to study cells. Electron microscopes provide higher magnification, higher resolution, and more detail than light microscopes

why are tomatoes red ?
Answer:
Tomatoes are triggered to turn red by a chemical called ethylene. Ethylene is odorless, tasteless, and invisible to the naked (human) eye.
Explanation:
Answer: As the tomato ripens, its color starts to change from green to yellow and then eventually to red. This is due to the breakdown of chlorophyll, which in turn synthesizes a red carotenoid (another pigment group), lycopene. When ripe, the carotenoid can easily be seen as the dominant color of the tomato, red

1.transport process,2.removing waste,3.reproduction,4.produce energy.
Hope the helps :)
Answer:
They give structure and support, help in reproduction, and enable development through mitosis. They also allow passive and active transport, produce energy, and initiate metabolic processes.
multiple sclerosis and atherosclerosis are similar in that they both refer to:
The conditions mentioned are both a type of sclerosis, which refers to the hardening of a certain anatomical feature.
In atherosclerosis, the affected anatomical feature is the artery. This is a condition that causes the obstructions of blood flow through the artery as a result of plaque buildup along the artery walls. Unlike with MS, atherosclerosis does not present symptoms until the obstructions are severe or the plaque loosens, which can lead to heart attacks, among other consequences.
In the case of Multiple Sclerosis, the affected anatomical structure is that of the nerve. This is a condition for unknown reasons, causes the immune system to attack the myelin covers of nerve cells which act to protect the cell. The absence of this cover causes the build-up of plaque along the nerve axon, stiffening and disrupting the communication of the nerves with the central nervous system.

what is the evidence that richard wrangham put forward to support his hypothesis that intraspecies aggressiveness was common in the last common ancestor of chimpanzees and humans?
The evidence that was put forward by Richard Wrangham to support his hypothesis that intraspecies aggressiveness was common in the last common ancestor of chimpanzees and humans is that chimpanzees conduct raid against individuals in neighboring territories.
Intraspecies aggressiveness is the form of aggressiveness between humans beings and other animals. They're a threat of action that brings about harm.
Richard Wrangham put forward evidence to support his hypothesis that intraspecies aggressiveness was common as he stated that chimpanzees conducted raid against individuals in neighboring territories.

What occurs when there is a higher concentration of molecules on one side of a membrane and the molecules flow to the other side to balance the concentration?
Answer:
diffusion
Explanation:
The concept of diffusion states that molecules like to travel from areas of high concentration to low concentration.
Let's think about an example. Let's say you are having a party at your house and in one room there is 100 people and in the other room connected to it, there is only 10 people. What do you think is going to happen as time passes? Right, people are going to move to the room where there is less people so as to equally disperse themselves across the area. The same thing happens within our body with ions and gases.
Ions can diffuse into or out of cells based off their concentration gradients. If there are too many ions on one side, they will simply move to the other side. There are different types of diffusion. Passive diffusion and facilitated diffusion, but those are for a different conversation.
It needs to accept electrons from calcium to have a full outer shell.
Answer:
mark me brainlest
Explanation:
Calcium, Ca , is located in group 2 of the periodic table, which means that is has two electrons on its outermost shell. In order to have a complete octet, calcium must lose these two outermost electrons, also called valence electrons. Calcium will react with nonmetals to form ionic compounds.

What is osmosis? ???
Answer:
In biology, osmosis is defined as the net movement of water molecules through a semipermeable membrane (e.g. cell membrane) from an area of higher to an area of lower water potential. Other definitions of osmosis are as follows:
The process of a solvent diffusing through a semipermeable membrane from an area of low solute concentration to an area of high solute concentration
The tendency of water to flow from a hypotonic solution (low concentration of dissolved substances) to hypertonic solution (higher concentration of dissolved substances) across a semipermeable membrane
In chemistry, osmosis is defined similarly. It is the passage of a pure solvent from a solution of lesser to one of greater concentration of solutes when the two solutions are separated by a membrane that selectively prevents the passage of solute molecules while allows the solvent molecules to pass through.
