Answer:
4. Catalase is a common enzyme found in nearly all living organisms exposed to oxygen which catalyzes the decomposition of hydrogen peroxide to water and oxygen.
5. hydrogen peroxide
6. the reactant is hydrogen peroxide H2O2
7.the products are water and oxygen, H2O and O2
Explanation:
5. catalase breaks down two hydrogen peroxide molecules to form oxygen.
7. H2O2> H2O + O2 , catalase acts as a catalyst.
Answer
To Design a Procedure
Explanation:
Scientist do experiments to study how things are affected by what they do and the change they are put through. Not to make it look better. Or to change the design.
The answer is B
You begin when your mouth begins to break down food. It travels down your esophagus and into your stomach. Then it goes into your small intestine first. The small intestine absorbs 90% of the nutrients and food. After that it goes to your large intestine. Your large intestine absorbs water and and electrolytes.
Answer:
This structure provides support and protection for plant cells = Cell Wall
This is a large, central fluid-filled structure that provides turgidity = Vacuole
A thin semipermeable barrier around the cell which regulates what enters and leaves the cell = Cell membrane
The control center of the cell = Nucleus
It is often described as the cells Power Plant = Mitochondria
This is used by plant cells for photosynthesis = Chloroplast
Hope this helps :)
Plz mark Brainliest :D
Explanation:
The giant blue thing is the vacuole
The thin yellow line is the cell membrane
The yellow and orange ball is the nucleus
The light green thing with zig zag lines is the mitochondria
The dark green thing inside the cell is the chloroplast
The thing outside the cell is the cell wall its green
Answer:
(a) H0: mu = 17 vs. Ha: mu < 17
(b) Sample statistic is 1.6
Explanation:
(a) A null hypothesis is a statement from a population parameter which is either rejected or accepted (fail to reject) the upon testing. It is expressed using the equality sign.
An alternate hypothesis is also a statement from a population parameter which negates the null hypothesis and is accepted if the null hypothesis is rejected. It is expressed using any of the inequality signs.
(b) Sample statistic = sample mean ÷ sample size = 16 ÷ 10 = 1.6
