Answer:
The constant improvement of the microscopes have resulted in the revisions in the cell theory because with each improvement some new detail about the cell structure is revealed by the microscopes. These new improvements led to the change sin the cell theory
Explanation:
Facilitated diffusion.
A protein channel is used to allow larger or charged molecules to enter/leave the cell.
Answer:
Many species would eventually die off because they lack a food source.
Explanation:
<u>Photosynthesis can be defined simply as the biological process of using light to synthesize food (in the form of glucose). It is a process that takes place in plants and involves the synthesis of sugar using inorganic products such as water and carbon dioxide.</u>

The process consists of two stages namely;
- Light reaction
- Light independent reaction.
The products from the light reaction are utilized in the light-independent reaction.
<em>Hence, without light energy, the process of photosynthesis cannot proceed and plants will not be able to manufacture foods. Without foods, many plant species would die off. </em>
Answer:
The correct answer is 1. EEG.
EEG or electroencephalography is a technique used to measure the electrical activity of the brain.
8 to 16 pairs of electrodes are placed on the scalp which record the electrical activity or impulses (in volts) generated by thousands of neurons or nerve cells present in the brain.
It provides the real-time imaging of the electrical activity of the brain.
The recorded impulses are first sent to the amplifier as the magnitude of the brain's electrical impulses is very low.
The amplifier then amplifies the results and show it on the screen in the form of voltage units.
Hello There!
It contains dissolved substances, cells and cell fragments.
The other parts of blood are:
Red blood cells - Carry blood around the body
White blood bells - Fight against bacteria and diseases
Platelets - Small fragments of bells. They are involved in forming blood clots.
Hope This Helps You!
Good Luck :)
