Cyanide interrupts the electron transporter chain. Pyruvate concentration DOES NOT CHANGE. NADH concentration INCREASES in the matrix, and H+ concentration DECREASES in the intermembrane space.
-----------------------------------
Let us firts make a quick revision of aerobic respiration.
Through cellular respiration, cells degrade organic compounds and produce energy.
Aerobic respiration takes place in three steps:
1) Glycolysis is the first step of cellular respiration. It occurs in the cytoplasm, and its final product is Pyruvate.
2) The Krebs cycle takes place in the mitochondria matrix.
3) The electron transporter chain is placed in the internal mitochondrial membrane.
*******************
We already know that cyanide affects the electron transporter chain. So, let us focus on its functioning under normal conditions and under the cyanide effect.
⇒ Under normal conditions,
• ATP is produced at the end of the electron transporter chain.
• The electron transporter chain constitutes a series of enzymatic reactions to release and save energy for the correct functioning of the organism.
• Along the chain, there are four proteinic complexes in the membrane, I, II, III, and IV, that contain the electrons transporters and the enzymes necessary to catalyze the electrons' transference from one complex to the other.
• Cytochrome oxidase (P450) is one of the enzymes involved in this electron transport.
• NADH and FADH2 provide electrons to the chain.
• While electrons move along the chain, complexes I, III, and IV pump protons to the intermembrane space.
• At the end of the chain, water molecules and ATP are produced.
⇒ Under cyanide effect,
• Ion cyanide inhibits cellular respiration.
• Cyanide binds to the ferric ion of cytochrome oxidase.
• Cyanide-ferric binding inactivates the enzyme and blocks electron transference.
• The chain is interrupted. Hence,
NADH and FADH2 stop providing electrons, complexes I, II, and IV stop pumping protons to the intermembrane space, there is no oxygen consumption and no ATP production.• Since muscles do not get to have ATP as a source of energy, they weaken.
• The interruption of the electron transporter chain produces an anaerobic state that could be culminating.
*************************
Now, let us answer the question
Pyruvate concentration ⇒ NO CHANGESince Pyruvate is produced in the cytoplasm, it is not affected by cyanide. Remember that cyanide only affects the electron transporter chain.
NADH concentration ⇒ INCREASE
Since NADH provides electrons to the chain, and Cyanide interrupts electron transport, there is an accumulation of NADH molecules in the matrix.
Intermembrane H+ concentration ⇒ DECREASE
Since the electron transporter chain is interrupted, no electrons are being carried, and no protons are being pumped to the intermembrane space.

what are the different ways of storing tools and equipment safe
answer is included in the picture below.
Answer:
Step 1
Delegate a portion of your garage, shed or basement closet as a place to store tools. Clean out the junk and clutter and make a space only for tools. Figure out how much space is needed for the amount of tools you have. Sweep away cobwebs, dirt and other foreign matter. Get a shelving unit and store chemicals, liquids and paint substances out of the reach of children and pets.
Step 2
Find the parts. Locate cords, bits, nails and screws and organize them. Allocate plastic bins to store smaller household tools. If you have a large tool collection, organize by type for easy location. Keep the parts for each specific tool close by.
Step 3
Clean out dirt and debris from tools. Oil power tools to lubricate moving parts. Repair loose handles and clean out oil or other fluids used to power the tool. Sharpen blades and replace worn out parts.
Step 4
Set up racks. Mount commercially available racks along the wall of your garage or storage area to hang garden tools, cords and other equipment. Screw racks into the wall with screws recommended by the manufacturer and a power drill. Wind long cords in a loop and hang from rack. Place tools on racks by the handle. Draw the outline of the tool with a permanent marker to identify its place, or use labels to mark the location.
Step 5
Create a library. For tools and appliances that have various functions, designate a library area or bin within the storage space for user manuals and warranty sheets. Store the booklets alphabetically and in a dry area. Type up a sheet listing all of the books to create simple table of contents.

Which type of rock has a coarse texture due to slow cooling in magma chambers?
A.extrusive
B.intrusive
C.metamorphic
D.sedimentary
Answer: Intrusive
Explanation:
If magma cools slowly, deep within the crust, the resulting rock is called intrusive or plutonic. The slow cooling process allows crystals to grow large, giving intrusive igneous rock a coarse-grained or phaneritic texture.
Hope this helps!! :D
Answer:
intrusive
Explanation:
Intrusive igneous rocks form at some depth within the crust due to slow cooling of magma, resulting in formation of large crystals. Individual crystals can be seen with the naked eye. These rocks are termed texturally as coarsely crystalline or phaneritic.

Answer: Sense food, Predators
Explanation: They can observe the animals odor and they can also observe the animals predators.
Scientists are inspired to the survey of animal behavior for a variety of reasons, and the ground is pretty varied, ranging from feeding behavior and habitat selection research to mating behavior and social organizations.
What is animal behavior?Animal behavior encompasses all of the ways in which animals interact with other organisms and their physical surroundings.
Behavior can also be defined as a change in an organism's activity in response to a stimulus, an external or internal cue, or a combination of cues.
Animal behavior connects the molecular and physiological aspects of biology to the ecological.
Behavior is the link between organisms and their surroundings, as well as between the nervous system and the ecosystem. One of the most important aspects of animal life is behavior.
Animal research helps scientists understand how living creatures, both human and animal, function.
Animal research allows us to get a close-up look at living organisms and how their physical, chemical, and functional life systems function.
Thus, this way, a scientist can learn many varied things regarding organisms by learning animal behavior.

What do you mean by Estuary?An Estuary may be defined as a type of ecotone that signifies the transitional zone of two different ecosystems which include the freshwater river ecosystem and the marine water ocean ecosystem.
In this ecotone, the characteristics of both ecosystems are present. Hence, it has a high biodiversity as compared to both ecosystems individually. This region shows maximum diversity and is thus known as the edge effect.
This illustrates that when nutrients in the ecotone increase, the number of life forms i.e. biodiversity increases.
Therefore, the correct option for this question is A.

Nitrogen is the following that is fixed from the atmosphere by bacteria. Thus, the correct option for this question is C.
How nitrogen is being fixed by bacteria?Nitrogen is being fixed with the action of nitrogen-fixing bacteria. These bacteria invade the root of the plants where they stimulate the formation of root nodules.
It is the region where bacteria convert the free form of nitrogen into ammonia. This inorganic form of nitrogen is utilized by plants for their proper growth and development.
The fixation of nitrogen in very important. This is because the atmosphere of the earth consists of 78% of free nitrogen which is not usable in form of living organisms. While the fixation of nitrogen converts this free form of nitrogen into usable forms. For example, it can be easily assimilated by plants and other living organisms.
Therefore, nitrogen is the following that is fixed from the atmosphere by bacteria. Thus, the correct option for this question is C.

B. Energy is needed to make this happen
C. It's facilitated diffusion.
D. It's osmosis.
Answer:
A) it is moving down the concentration gradient
Explanation:
Brownian motion will cause the molecules (or ions) to spread/diffuse from where they are more concentrated to where they are less concentrated until they are equally distributed in that space (Figure). When molecules move in this way, they are said to move down their concentration gradient.
