If someone where to ask you to determine the purity of the substance, what would they mean? Why is purity important in crime investigations?

Answers

not exactly sure, but maybe because the powder might have something important like dna.

Answer: #1: If I was a forensic scientist and is given an unknown powder from a crime scene, I would hope to find out if the substance contains drugs or any other component that could be dangerous, and to be treated in a proper way.

2#If some would ask me to determine the purity of an unknown powder that contains illegal drugs like cocaine, they would probably be wanting to remove other substances that are added like baking soda, and the reason this is so important is that sometimes the ingredients they get to mix with have an effect on the test and may miss lid the results.

Explanation:

how are highly folded membranes an advantage for the functions of cellular parts? Name an organelle that has highly folded membranes.

Answers

Answer:

Membrane folds of an organelle increase the surface area where chemical reactions occur, this is very advantageous. One organelle that has folds in the membrane is mitochondria.

Explanation:

Mitochondria are formed by two lipoprotein membranes, one external and one internal:

External membrane: Similar to other organelles, smooth and composed of lipids and proteins called deporins, which control the entry of molecules, allowing the passage of some relatively large.
Inner membrane: It is less permeable and has numerous folds, called mitochondrial ridges. These folds have a great advantage for mitochondria as they increase the surface area where chemical reactions occur.

A highly folded membrane is an advantage for the function of celluar parts because is divides pieces in the cell, creatimg an easier transportation route. An organelle with highly folded membranes is the endoplasmic reticulum.

Auxins _____. promote cell elongation and cell division in stems stimulates seed growth and fruit development promotes cell division regulates the opening and closing of stomata

Answers

Auxins promote cell elongation and cell division in stems.

The correct answer is option A

Auxin promotes cell elongation and cell division in stems. They promote stem elongation and inhibits the growth of lateral buds.

This plant hormone is produced in the stem tip and then it travels to the darker side of the plant so that the cells in the darker side grows more than the cells in the lighter side of the plant.

I WILL MARK BRAINIEST IF ITS RIGHTWhich are functions of the stomata in the leaves of seed plants? Check all that apply.

reduce water loss
make glucose
absorb sunlight
take in carbon dioxide
produce oxygen

Answers

Answer:

Reduce water loss

Explanation:

Stomata allow a plant to take in carbon dioxide, which is needed for photosynthesis. They also help to reduce water loss by closing when conditions are hot or dry. Stomata look like tiny mouths which open and close as they assist in transpiration.

Sorry if it's wrong

produce oxygen and reduce water loss i believe

What is the chemical equation for cellular respiration?

Answers

Correct answer is:

$C_(6)H_(12)O_6+6O_(2)\Rightarrow 6CO_(2)+6H_(2)O+energy$

But how to get there?

Let's start with simple explanation of what exactly is cellular respiration.

Cellular respiration is a multistage biochemical oxidation process of organic substances when prime product is energy (ATP - adenosine triphosphate) and other are released waste products.

Cellular respiration takes place even if other metabolic processes are stopped, but cellular respiration may differ in particular organism groups.

Some reactions during whole process of cellular respiration are similar in all types of living organisms.

Cellular respiration is prime indication of declining living processes.

Only viruses which are on the edge of living organism and chemical particle are not performing cellular respiration.

But to the point :P

In cellular respiration all substrates which are in the cell might be organic, but mostly we are using sugar oxidation - glucose in the presence of oxygen.

Chemical formula of sugar looks like this:

$C_(6)H_(12)O_6$

Oxygen is just $O_2$

so for now we have just part of the equation:

$C_(6)H_(12)O_6+O_(2)\Rightarrow$

But what would be on the right hand side?

It's quite simple, remember equation of full combustion? If we want to burn something we need oxygen like in the equation, so the product of this equation would be carbon dioxide, water and of course energy (ATP).

Carbon dioxide formula looks like this:

$CO_(2)$

As a reminder water formula:

$H_(2)O$

Full formula would look like that:

$C_(6)H_(12)O_6+O_(2)\Rightarrow\ CO_(2)+H_(2)O+energy$

But still as you see this equation is unbalanced, after balancing it would like that:

$C_(6)H_(12)O_6+6O_(2)\Rightarrow 6CO_(2)+6H_(2)O+energy$

At the end I would like to explain one more thing. Energy which has been released during this process is part of high-energy connection which might be used to perform chemical reactions in the cell or to move organism for example in muscles. We need to remember that production of ATP is not happening with 100% efficiency and part of this energy is released as heat.

$C_(6) H_(12) O_(6) +6O_(2) ---\ \textgreater \ 6CO_(2) +6H_(2) O+ENRGY$
