mutation is a change that occurs in our DNA sequence.some mutation has a positive effect on organisms in which they occur, they are also called beneficial mutation. such causes a body to produce certain proteins which are helpful in for organism to adapt to changes in environment.
Answer:
Lake - hydrosphere
Water vapor - hydrosphere
Glaciers and icebergs - cryosphere or the hydrosphere
The Rocky Mountains - lithosphere
A deer - biosphere
Explanation:
There are four main spheres of the earth- The atmosphere (air), the biosphere (living things), the lithosphere (earth) and the hydrosphere (water).
The lakes are part of the hydrosphere
Water vapor present in the air is part of the hydrosphere
The Glaciers and icebergs are a part of the cryosphere (frozen form of water) or the hydrosphere
The Rocky Mountains are a part of the lithosphere
A deer is part of the biosphere
Answer: Antibodies are proteins that are found in the body on the surface of red blood cells and in the blood plasma ,they are very sensitive to foreign bodies and bad viruses and bacteria,when they notice the presence of anything that poses harm or a threat to the body system,they track it down and fight/destroy it.
Antibodies also play crucial role in hemostasis(stoppage of bleeding) in the sense that when the body is wounded or when someone gets a cut antibodies that are found in the plasma and some substances found in the platelets are released to play a role in sending signal to the blood clotting factors in the blood to be released to arrest the bleeding and prevent the person from bleeding out their entire blood.
Answer;
When only white and red lights are visible, you are approaching the port side of a powerboat and thus you should give way to your starboard side.
Explanation;
-The red and green lights are called sidelights (or combination lights) because they are visible to another vessel approaching from the side or head-on. The red light indicates a vessel's port (left) side; the green indicates a vessel's starboard (right) side.
-When only a white light is visible, one may be overtaking another vessel. Give way to either side. Additionally, when only a red light is visible, you are approaching the port side of a sailboat.
Cyanobacteria play an important role in the biosphere by converting atmospheric nitrogen into mineral nitrogen directly assimilated by other organisms. This capacity is of fundamental importance in coral reefs where nutrients are scarce.
Moreover, Cyanobacteria are the micro-organisms of choice for humans in various branches of biotechnology because of the many families of molecules that they produce and which have an interest in valorization.
