Answer:

The answer is they reproduce with only one another.

Explanation:

In biology, species is a term that can be defined as a group of organisms that can reproduce with one another and give birth to fertile offspring. In other words, the organisms in one species cannot reproduce with organisms in another species. So, to be considered as part of the species, this criteria is very important.

Answer:   Long term storage of energy

Explanation:  Triglycerides are the fats or basically lipids which are found in the blood.

They are the source of the long term storage of energy.

They are primarily used as storage of the energy because the its oxidation will produce twice as much energy than the oxidation of the carbohydrates.

Thus it is better to store the energy which we take from the food to store as triglyceride.

During cellular respiration, chemical energy in glucose is converted to ATP, conserving energy efficiently across glycolysis, the Krebs cycle, and the electron transport chain. Energy conservation ensures no net loss of matter or energy, illustrating a fundamental principle of biology where substances can change form but are never lost.

During cellular respiration, the type of energy transformation that takes place involves converting the chemical energy stored in glucose into a form that cells can use, primarily adenosine triphosphate (ATP). This process begins with glucose and oxygen being transformed into carbon dioxide, water, and energy. The conservation of energy during cellular respiration occurs through a series of biochemical reactions that extract energy from glucose and transfer it to ATP, which cells utilize for various functions. The overall process encompasses three main stages: glycolysis, the Krebs cycle (or citric acid cycle), and the electron transport chain.

In cellular respiration, there is no net loss of matter or energy as they are both conserved. Glucose, upon oxidation, releases its energy in a controlled manner through several steps. This released energy is captured in the form of high-energy phosphate bonds in ATP. ATP then serves as a versatile energy currency for the cell, enabling it to perform various tasks such as muscular contractions, nerve impulses, and biosynthesis. The efficiency of this process means energy is conserved within biological systems, maintaining life processes without waste.

Mitosis is the process by which skin cells divide to repair damages such as scratches, producing two genetically identical daughter cells, ensuring the integrity and functionality of the skin.

Explanation:

Mitosis is a fundamental process that occurs in somatic cells, such as skin cells, to facilitate growth and repair through the production of identical daughter cells. For example, when you incur a scratch, your body initiates mitosis to produce new skin cells to heal the wound. During mitosis, a skin cell will duplicate its DNA and divide into two new cells, each with the same number of chromosomes as the original cell, ensuring that the repaired skin is genetically identical to the surrounding area. This process is crucial for maintaining the integrity and functionality of our skin, as well as other bodily tissues.

Mitosis is the process of somatic cell division that results in two identical daughter cells. In the case of a skin cell, mitosis is responsible for regenerating new skin cells when you get a cut or scratch.

The automatic switch in an electric kettle saves energy by cutting off power when the water inside boils. By reducing the time over which power is consumed, the automatic switch prevents the kettle from wasting energy.

The automatic switch in an electric kettle saves energy by shutting off power to the kettle once the water inside reaches its boiling point. This prevents the kettle from consuming unnecessary power and thereby wastefully heating water that's already boiling. Without the automatic switch, the kettle would continue to draw electricity, converting it to heat, even after the water is boiling. This automation reduces the time over which power is consumed, leading to fewer units of energy used.

An example of this can be likened to a light bulb that is turned off when not in use. Even if it consumes high power, the light bulb does not waste energy because it is only in operation for the necessary period, wherein the automatic switch in the kettle plays the role of a person switching off the light bulb.

So, it is through this method of selectively controlling the 'on' state of the electrical device, the electric kettle in this case, significant energy savings can be realized over time.

Answer:

Original pressure = P1 = 11.3 atm

Final volume = V2 = 24.5 L

Explanation:

Given data:

Initial conditions:

Volume V1 = 0.851 L

Temperature T1 = 150.0 K

Moles of He n1 = 0.783

From ideal gas equation:

[tex]PV = nRT\\\\P = \frac{nRT}{V}[/tex]

NO₂⁻ is the reducing agent, H⁺ is neither, and Cr₂O₇²⁻ is the oxidizing agent in the given redox reaction.

Here's the classification of each reactant:

NO₂⁻ (Nitrite ion): Reducing Agent - This reactant loses electrons (is oxidized) and reduces another substance. Specifically, it changes from NO₂⁻ to NO₃⁻.

H⁺ (Hydrogen ion): Neither - This reactant merely provides the acidic environment necessary for the reaction but does not undergo a redox change itself.

Cr₂O₇²⁻ (Dichromate ion): Oxidizing Agent - This reactant gains electrons (is reduced) and oxidizes another substance. Specifically, it changes from Cr₂O₇²⁻ to Cr³⁺.

Thus, in the reaction, NO₂⁻ serves as the reducing agent, H⁺ does not alter its oxidation state and is neither, and Cr₂O₇²⁻ serves as the oxidizing agent.

Answer: The correct answer is Option C.

Explanation:

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

This also means that total mass on the reactant side must be equal to the total mass on the product side.

The chemical equation for the decomposition of limestone follows:

[tex]CaCO_3\rightarrow CaO+CO_2[/tex]

Let the mass of calcium oxide be 'x' grams

We are given:

Mass of carbon dioxide = 88 grams

Mass of calcium carbonate = 200 grams

Total mass on reactant side = 200 g

Total mass on product side = 88 + x

So, by applying law of conservation of mass, we get:

[tex]200=88+x\\\\x=112g[/tex]

The mass of calcium oxide that would be produced is 112 grams.

Hence, the correct answer is Option C.

Water table is the underground region between where water saturates pores and where it does not.

Answer: B

Explanation

It is known that water is present below the ground. The rocky terrain inside the ground contains water and the water will be filled in the pores between the rocks.

The water filled in the saturated region below the ground is separated from the unsaturated region which is the region above the ground by a surface termed as water table.

The unsaturated region is the soil above the ground and the plants get water from this region.

The water is present in unsaturated region occupy between the pores of rocks and soils but they are loosely filled so that plants can extract water from them.

Then below the ground water table region will be present and below the water table the saturated water region is present.

So water table is the region dividing the saturated and unsaturated water pore regions.
