Villi occur in the digestive system, helping to move food through your system and absorbing nutrients.
Flooding is the term used to characterize the process that occurs when the waters of a river overflow due to rain and occupy the area next to the river, called the river plain. It can have natural or anthropogenic causes and affect vulnerable populations more often.
<h3>What is Biotic and Abiotic?</h3>
The biotic components are all the living things that live in a certain place, while the abiotic components are all the physical, chemical and geological factors of the environment such as water, light, soil, humidity, temperature, nutrients etc.
With this information, we can conclude that A flood can wash away important abiotic factors, such as soil and rocks, that certain biotic factors need to survive, thus flooding affects the ecology of affected regions.

If it's a microscope it should be on the low power setting (10x) and you should only use the course adjustment knob which is the bigger one.
Answer:
4. wedge and lever
Explanation:
Simple machines are mechanical devices which make our work easier. Examples are : lever, wedge, wheel and axel, pulley, screw and an incline plane.
A stapler is a made up of a level which is the handle part and a wedge which are the staples.
A pulley is a simple machine that has one or more wheels connected with a rope in a loop to make lifting of loads easier because it changes the direction of force applied/pull thus multiplying the force applied. <em>A stapler does not have the wheel and the rope thus answer choice 1 and 2 are incorrect.</em>
A screw is a simple machine that applies torque on a shaft to produce a large axial force on the load. It utilizes the conversion of rotational motion to a linear motion and a torque to a linear force. <em>A stapler mechanism does not involve rotational motion or rotational force, hence answer option 3 is incorrect.</em>
Role of tRNA in translation
tRNA is responsible for bringing amino acids to to developing chain amino acids on sequence of mRNA through ribosomes.
