Answer:
Cilia and flagella are slender, hair-like structures that protrude from many types of cells. In many cells, cilia act as a fundamental unit of motion, serving as key organelles that convert chemical energy into mechanical work in the form of an oscillatory beating motion.Flagella acts primarily as an organelle of locomotion in the cells of many living organisms.In multicellular organisms, cilia function to move a cell or group of cells or to help transport fluid or materials past them.Cilia are present on the surface of the cell in much greater numbers. Ciliated cells often have hundreds of cilia but flagellated cells usually have a single flagellum. The function of cilia is to move water relative to the cell in a regular movement of the cilia.

The figure below shows what happens to the pH of two solutions when an acid is added. Use the key above the image to answer the questions about the image.
1) Acid
2) Base
3) Experiment 2
Explanation:1) In Experiment 1, when the acid is added, the color of the solution goes from light (suggesting base) to dark (suggesting acid). As such in this case, adding the acid resulted in an ACIDIC solution.
2)The opposite is true in Experiment 2. When the acid is added, the color remains light (suggesting base). As such in this case, the resulting solution is BASIC.
3) Experiment 2 is when the acid is added to buffer the base. A buffer solution, as you remember, is a solution the resists changes to pH when an acid or base is added. Since the addition of the acid in Experiment 2 was done so the pH doesn't change as drastically as in Experiment 1, then we can conclude that it was done to create a buffer solution.
I hope this helps. Let me know if you need any clarification. I am happy to provide it.
A buffer solution is one that can resist changes in pH when an acid or base is added to it.
In Experiment 1, adding an acid to a basic solution would likely result in the solution moving closer to neutral or becoming less basic. So, it might still be slightly basic but less so.
In Experiment 2, adding an acid to a basic solution would likely result in the solution moving closer to neutral or becoming less basic, similar to Experiment 1.
From the information given, it's not possible to definitively determine in which experiment the acid is added to a buffered base. However, a buffer solution is one that can resist changes in pH when an acid or base is added to it. If either of the experiments involves a solution that shows a relatively small change in pH upon adding the acid (compared to what would be expected without buffering), that could be an indication that the acid is being added to a buffered base.

which part of the nervous system is most immediately activated by sudden fear?
Answer:
The Amygdala
Explanation:
The fear response starts in a region of the brain called the amygdala. This almond-shaped set of nuclei in the temporal lobe of the brain is dedicated to detecting the emotional salience of the stimuli – how much something stands out to us.

If you are the first to answer I will mark you as braininess but the answer must be correct
Answer:
As per my full understanding,
There are two main modes of nutrition:
Autotrophic – Plants exhibit autotrophic nutrition and are called primary producers. Plants synthesis their food by using light, carbon dioxide and water.
Heterotrophic – Both animals and human beings are called heterotrophs, as they depend on plants for their food.
WHEREBY: TERMS IN THIS TWO SETS ARE:
Chemohetrotroph. Gets energy from chemicals and carbon from other sources.
Photohetrotroph. Gets energy from light and carbon from other sources.
Chemoautotroph. Gets energy from chemicals and produces its own carbon.
Photoautotroph. Gets energy from light and produces its own carbon.
