The illustration below represents the movement of materials involved in a process that is vital for the energy-production and energy-transfer needs of an organism.
Oxygen
Water
Mamm
Glucose Carbon dioxide
In which organelle does this process take place?
Answer:
mitochondrion
Explanation:
The correct answer would be the mitochondrion.
The process of energy production in living organisms happens through oxidative phosphorylation during respiration. The process takes place in the mitochondrion. During respiration, glucose reacts with oxygen to produce carbon dioxide and water while ATP is generated in the process. The ATP represents the energy currency of the cell.
The entire process of respiration can be summarized by the following equation:
[tex]C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP[/tex]

1. The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction. Exceptions to this are the action of cilia, the flagellum on sperm cells, and amoeboid movement of some white blood cells.
2.
Skeletal: It is a form of striated muscle tissue which is under the voluntary control of the somatic nervous system. Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons.
Smooth: composed of sheets or strands of smooth muscle cells. These cells have fibers of actin and myosin which run through the cell and are supported by a framework of other proteins.
Cardiac: It is an involuntary, striated muscle that constitutes the main tissue of the walls of the heart.
3. Voluntary muscles or striated muscles are those which work according to the one’s desire or are under control, whereas Involuntary muscles are not under one’s control. Biceps muscles, respiratory, alimentary and urogenital tracts are the places where voluntary muscles are found, while abdominal muscles, locomotory muscles, middle ear muscles, Diaphragm are the examples of the involuntary muscles.
4.
1st pic: Cardiac
2nd pic: smooth
3rd: Skeletal
5. Skeletal muscle is metabolically and mechanically maladapted to working as the muscle that causes the heart beat. The cardiac muscle has a much higher capacity to extract oxygen from the blood than any skeletal muscle with a higher mitochondrial density so the skeletal muscle heart would, at rest, be working at very near to its metabolic limits. This would not allow the body to do much exercise. The characteristics of skeletal muscle contraction are not the same as the characteristics of cardiac muscle contraction. Cardiac muscle is essentially a network of muscle fibers where most of the signal to contract is propagated by the fibers themselves and the contraction of the whole muscle occurs. The heart beat entails the whole heart contracting at a slower rate of contraction than skeletal muscle. I would conjecture that the relatively slow concentric beat of the whole heart would be better for pumping fluid than the more rapid beat of skeletal muscle. Nerves stimulate any number of motor units in skeletal muscle which, depending on how many nerves are activated, will allow fine gradations in muscle strength. This kind of control would not be necessary for the heart , so inefficient.

SOMEONE PLEASE HELP ME OUT WITH THIS PLEASE HELP ME!!!
Answer:
I think it's C but it could also be D. In my opinion all of them are complex in their own ways.
Explanation:
Please help me IDENTIFY THE PHASES OF MEIOSIS
Answer:
1. Anaphase I
2. Anaphase II
3. Prophase I
4. Metaphase I
5. Metaphase II
6. Telophase I
7. Prophase II
8. cytokinesis
Explanation:
The first image or diagram shows that the chromosomes are pulled apart while sister chromatitds are attached to one another. This is took place in the anaphase I phase.
In second diagram the sister chrmoatids are become unattached and moves or pulled towards the opposite poles. It is Anaphase II stage.
In the third image or illustration there is formation of synapsis complex and chiasmata which takes place in prophase I.
In the fourth image the pair of chromosome lined up on the equator this characterstic feature of metaphase I.
In the fifth image sister chromatids are line up on the equator which is take place in metaphase II.
In the sixth image chromosomes reach on opposite ends and formation of nuclear envelope takes place which is take place in telophase I.
The seventh image is showing the condensation of chromosome and adestruction of nuclear envelope as occurs in the prophase II.
Formation of cells and divide into four individual cells is the process of cytokinesis.

The answer is C
Explanation:
Answer:
I think the answer is C, so sorry if I got it wrong.
ucia was comparing animal and plant cells under a microscope. She thought that she was looking at plant cells. Lucia asked her science teacher to take a look and see if she was correct. Lucia’s teacher looked at the cells and told her that she was correct. What did both Lucia and her teacher see under the microscope?A.a large nucleus in each cellB.a large vacuole in each cellC.cells that had irregular shapesD.a membrane surrounding each cell
Answer: B.
Explanation:
A large vacuole in each cell because vacuole is only present in plant cells and not animal cells.
Which of the following is an example of a physical variable of water quality *
Answer: Physical properties of water quality include temperature and turbidity. While chemical characteristics involve parameters such as pH and dissolved oxygen. These parameters are relevant not only to surface water studies of the ocean, lakes and rivers, but to groundwater and industrial processes as well.
I hope this is the answer if not I apologize :P
Answer:
One of the physical variables that affect the properties of water is temperature
Explanation:
I assume that by physical properties you mean external factors that affect the properties of the water correct? well depending on the temperature of the air that the water is exposed to the war can shift from either a liquid to a solid if it if the air is cold or it can change from a liquid to a gas when the air is hot. I'll explain how this works when the temperature of the air is hot the water will under go an exo thermic reaction (A reaction that causes things to emit heat and become hot) and because water boils at a certain point as the water gets hotter and hotter it will evaporate into mist. If the air around the water is cold then it produces an endothermic reaction which will cause the ice to get colder and colder as time goes on until it transitions from being a liquid to a solid in the form of ice. Hope this helps:)

Answer:
B.
Explanation:
why don't mercury and venus have moons
Answer:
Because Mercury and Venus are too close to the Sun and its gravity.
Explanation:
Mercury and Venus do not have moons because of their proximity to the Sun and their specific orbital characteristics.
Both planets are located relatively close to the Sun, and their gravitational interaction with the Sun is strong.
Additionally, their orbits are relatively stable, which means that any small celestial bodies that might have approached them in the past were likely captured by the Sun's gravitational pull or flung out of the solar system.
Unlike outer planets such as Jupiter and Saturn, which have strong gravitational influences and numerous moons, the inner planets like Mercury and Venus have not been conducive to capturing or retaining moons due to their specific orbital dynamics.
