The input of cell systems share are glucose and oxygen. The output of cell systems share are carbon dioxide, energy and water.

What is a cell ?

The smallest unit that can sustain life on its own and makes up all living things, including the body's tissues. The cell membrane, the nucleus, and the cytoplasm are the three primary components of a cell. The chemicals that enter and leave the cell are governed by the cell membrane, which encloses the cell.

The cell membrane, the nucleus, and the cytoplasm are the three components that make up a cell. Intricate arrangements of microscopic fibers and hundreds or even thousands of tiny, unique structures known as organelles can be found in the cytoplasm.

The system's inputs are the signals or data it receives, and its outputs are the signals or data it sends. As part of an activity, the phrase can also be employed; for example, to "perform I/O" is to carry out an input or output operation.

Thus, The input of cell systems share are glucose and oxygen. The output of cell systems share are carbon dioxide, energy and water.

If a substance is a bad conductor as a solid, but a good conductor as a liquid or when dissolved into water, which type of bond is holding the compound together?

Answers

an ionic bond. covalent bonds do not conduct in a solid or a liquid state, ionic bonds conduct in a liquid state and not in a solid state.

The bond type in the substance is ionic bonding because, ionic compounds in their solid state are not conducting but the ions they furnish when dissolved in water conducts electricity.

What are ionic compounds ?

Ionic compounds are formed between metals and nonmetals. Metals are electropositive and they can easily loss electrons to from cations. Metals donate electrons to the electron deficient non metals to achieve octet.

Ionic bonding is a strong electrostatic force between opposite charged ions. Hence this bond is stronger than other types of bond. This intact bonding make them bad conductors in the solid state.

However they are electrically conducting the molten state or when dissolved in water due to the presence of free ions and electrons in the solution.

Answers

Answer:

bacterial cell plant cells dont have a tail

Explanation:

The type of cell shown in the diagram is the bacterial cell as plant cell do not have tails while bacteria have tail.

Bacteria are prokaryotic unicellular organisms. They have a relatively simple cell structure compared to eukaryotic cells. They also do not possess any membrane-bound organelles such as a nucleus. However, do they possess genetic material (DNA or RNA) in the intracellular space called the nucleoid.

Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes. Prokaryotes are the dominant living creatures on Earth, having been present for perhaps three-quarters of Earth history and having adapted to almost all available ecological habitats.

There have been made 2 attempts of oxygen production by potassium permanganate.In the first attempt they have got 75ml oxygen in 3 minutes whearas there have been got 100ml in 5 minutes by the 2nd attempt.In what case the speed of the oxygen production is bigger???
Pls explain your answer

Answers

Answer:

The speed of oxygen production is bigger in the first attempt.

Explanation:

In the first attempt, since 75ml oxygen is produced in 3 minutes, the rate of oxygen production is r = volume of oxygen/time = 75 ml/3 min = 25 ml//min

In the second attempt, since 100ml oxygen is produced in 5 minutes, the rate of oxygen production is r' = volume of oxygen/time = 100 ml/5 min = 20 ml//min

Since r = 25 ml/min > r' = 20 ml/min, the speed of oxygen production is bigger in the first attempt.

Calculate the vapor pressure (in torr) of a 35°C solution of ethanol and propanol where the mole fraction of propanol is .75. Assume Ideal behavior P°ethanol35=100torr P°propanol35=36torr

Answers

The vapor pressure (in torr) of a 35°C solution : 52 torr

Further explanation

Given

x propanol = 0.75

P°ethanol=100 torr

P°propanol=36 torr

Required

the vapor pressure

Solution

Raoult's Law

P solution = xA.P°A +xB.P°B

x ethanol = 1- 0.75 = 0.25

Input the value :

P solution = 0.25 x 100 + 0.75 x 36

P solution = 25 + 27

P solution = 52 torr

Answer:

Not balanced. There are different number of atoms on each side of equation.

Explanation:

Given balanced chemical equation:

Chemical equation:

3C₂H₄ + 3O₂    →       4CO₂ + 6H₂O

The equation is not balanced because  umber of moles of C, H and O are not balanced. It consist of six moles of C, 12 moles of H and six moles of oxygen on left side of equation while on right side there are 4 moles of C fourteen moles of oxygen and twelve moles of hydrogen present.

Balanced chemical equation:

C₂H₄ + 3O₂    →       2CO₂ + 2H₂O

Now the equation became balanced. There are two moles of carbon, four moles of hydrogen and six moles of oxygen are present on both side of equation.
