Answer:

The cell membrane is selectively permeable, which controls the movement of materials in and out of the cell by passive and active transport.

Explanation:

According to this question, animal cells are made up of the following contents: 90% water and 10% protein, carbohydrates, nucleic acid, lipids and other molecules. The cell regulates this internal composition in a stable way via a process called HOMEOSTASIS.

The animal cell is able to regulate or maintain a stable internal composition by the possession of a selective permeable membrane called CELL MEMBRANE. The cell membrane is semi-permeable in the sense that it allows the entry of some molecules into and out of the cell and blocks others.

Some molecules are allowed by the cell membrane without the need for energy input in a transport called PASSIVE TRANSPORT while some requires energy input in a transport called ACTIVE TRANSPORT.

A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. Animal cells simply have a cell membrane, but no cell wall.

Answer:

A difference between plant cells and animal cells is that most animal cells are round whereas most plant cells are rectangular

Plant cells have a rigid cell wall that surrounds the cell membrane

Answer:

The G0 phase describes a cellular state outside of the replicative cell cycle. Classically, cells were thought to enter G0 primarily due to environmental factors, like nutrient deprivation, that limited the resources necessary for proliferation. Thus it was thought of as a resting phase.

Answer:

The word ‘diffusion’ means free movement across distance, with or without the presence of a barrier. However, there is a phenomenon known as facilitated diffusion which occurs at the cellular level. The cell does not allow free radicals and other harmful substances to enter and harm the cell organs.

Explanation:

Answer:

When certain large molecules are unable to move through the membrane without the help of channel proteins.

Explanation:

Facilitated diffusion occurs when large molecules that are unable to pass through a membrane on their own make use of channel proteins to move from one side of the membrane to the other. Facilitated diffusion can occur when a liquid on one side of a membrane has a higher osmotic pressure than a liquid on the other side of the membrane, but it isn’t a required feature of facilitated diffusion. Similarly, facilitated diffusion can occur when there’s a large membrane potential present, but it isn’t a required feature of facilitated diffusion. Facilitated diffusion doesn’t require the use of energy, so the presence of ATP is irrelevant to facilitated diffusion occurring.

As stating the liquid properties of matter, a liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a constant volume independent of pressure. It is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape.

Artificial selection and domestication is where humans take matters into their own hands. And instead of waiting for nature to do things, they are the selection factor. ... And when you have that type of artificial selection, the change can happen much, much faster. Breeding is essentially artificial selection.

Answer:

If ATP and NADPH are already used up at night , the production of glucose will stop.

Explanation:

IMPORTANCE OF ATP AND NADPH -: To temporarily store energy, the light-dependent reactions generate ATP and either NADPH or NADH. In light-independent reactions, these energy carriers are used to drive the energetically unfavorable mechanism of "fixing" organically inorganic CO2.

ATP is the molecular energy "currency" in biological systems. All energy produced by living organisms' cellular respiration must end up being used as ATP to power it. NADPH is a hydrogen carrier molecule reduced by NADP (Nicotinamide Adenine Dinucleotide Phosphate). While the light-dependent reactions take place, energized electrons hop on to electron carriers excited by photon energy from the sun (On Photosystem 2) and finally get to Photosystem one.

If ATP and NADPH are already used up at night, the fixation of carbon dioxide into glucose will halt. In other words, the light-independent reaction of photosynthesis will stop.

There are essentially 2 reactions in photosynthesis:

In the light-dependent reaction, radiant energy is used to excite electrons chlorophyll molecules while electrons in water replace the excited electrons. ATP and NADPH are generated in the process.

The ATP and NADPH produced during the light-dependent reaction of photosynthesis are essential for the reduction of carbon dioxide into glucose in the light-independent reaction.

Hence, unless the light-dependent reaction takes place to make ATP and NADPH available, there is no other way to produce the precursors for the fixation of carbon dioxide into glucose.

Answer:

A cell may vary the rate of an enzyme controlled reaction by making more/less or degrading more/less.

Explanation:

A cell may vary the rate of an enzyme controlled reaction by making more/less or degrading more/less. Several factors affect the rate at which enzymatic reactions proceed include post translational modifications, substrate concentration, cofactors, temperature, pH, locations. The shape and structure of the enzyme will change as the pH value of the reaction medium changes.

A cell may vary the rate of an enzyme controlled reaction by:

According to the given question, we can see that we need to show how a cell can vary the rate of a reaction which is controlled by an enzyme.

As a result of this, we can see that there are different ways through which a cell may control the rate of reaction in an enzyme controlled state which are by the level of degradation with time.

Answer:

Mass is not conserved in chemical reactions. ... This means that the total mass and energy before a reaction in a closed system equals the total mass and energy after the reaction. According to Einstein's famous equation, E = mc2, mass can be transformed into energy and energy can be transformed into mass.

Explanation:

Answer:

Mass is not conserved in chemical reactions. The fundamental conservation law of the universe is the conservation of mass-energy. This means that the total mass and energy before a reaction in a closed system equals the total mass and energy after the reaction. According to Einstein's famous equation, E = mc2, mass can be transformed into energy and energy can be transformed into mass. This is not some exotic process, but in fact happens every time there is a reaction. Mass is therefore never conserved because a little of it turns into energy (or a little energy turns into mass) in every reaction.

Comets are small bodies that go around/orbit the sun. A comet can also pack more damaging force than even an asteroid of the same mass. The dusty particles combined with ice and water, become the amazing beginning of a Comet.

When a comet or comets come within a certain distance of the Sun, they sublimate, which is another word for going from a solid-state to a gas without ever becoming a liquid.

Answer:

The desert and tundra biomes have very different temperatures as well as extremely different plants and animals. The desert can get very hot during the day, but cool off quickly at night. It has sandy soil and supports very little plant life. Animals found in the desert include lizards, javelinas, Gila monsters, coyotes, bobcats, scorpions, and kangaroo rats. The tundra is cold, dry, and often dark. The average temperature is about 10°F. The soil below the surface is permanently frozen, and is called permafrost. A few types of plants grow during the short summer season. Animals found in the tundra include caribou, foxes, wolves, and Arctic hares.
