Answer:
A simple machine uses a single force to do work against a single load force. friction losses, the work done on the load is equal to the work done by the applied force. The machine can increase the amount of the output force as well. The ratio of the output to the given force is mechanical advantage.
Explanation:
I love simple machines
Hopefully this helps you :)
pls mark brainlest ;)
Answer:
<u>Cuticle</u> - It also has a waxy material that protects the leaf from attacks by bacteria, protects inner tissues from mechanical damage and acts as a water proof layer to prevent excessive water loss.
<u>Palisade mesophyll</u> - They have many chloroplasts used to absorb light energy used for photosynthesis.
<u>Spongy mesophyll</u> - The cells are loosely packed together leaving air spaces that allow for air circulation and gaseous exchange.
<u>Guard cell</u> - They have thick inner walls and thin outer walls to control the opening and closing of the stomata.
Asexual reproduction; also known as mitosis and BINARY FISSION
It produces the new vascular tissues.?
The correct answer is A. Bases pairs, DNA, Gene, Chromosome, Cell.
Explanation
Nitrogen bases are chemical compounds that compose DNA and RNA, in the case of DNA the bases are adenine, thymine, guanine, and cytosine, while RNA is made up of uracil, adenine, guanine, and cytosine. Additionally, DNA makes up genes, which are structures that store information that is passed on to offspring. Also, genes are organized to form chromosomes (more complex structures) of genetic information. Finally, there are cells, in them are chromosomes, fundamental for the reproduction of an organism. Therefore, the correct answer is A. Bases pairs, DNA, Gene, Chromosome, Cell.
