Explanation:

The ATP molecule is like the tank of the delivery truck, while the glucose molecule is like the gas tank of the car.

What are molecules?

A molecule is a collection of two or more chemically bound atoms, whether they are from the same element or another. One molecule of water is created, for instance, when two hydrogen atoms and one oxygen atom combine.

ATP is a biological molecule that stores chemical energy needed by all living cells for metabolic activities. ATP is synthesized during the process of cellular respiration. Glucose molecules are products of digestion in our system, and they hold energy in their bonds. In the process of cellular respiration, glucose molecules are broken down and used to synthesize ATP.

Therefore, ATP molecule is like the tank of the delivery truck, while the glucose molecule is like the gas tank of the car.

The mangrove forest which holds the most Carbon dioxide followed by forest shown by second image and at last the vegetation on farms holds and releases the least amount of Carbon dioxide.

Carbon is transferred through one storage reservoir to another through a range of mechanisms. Plants, for example, transfer carbon dioxide from the atmosphere into the biome via photosynthesis in the food chain. They use solar energy to chemically incorporate carbon dioxide, hydrogen, and oxygen from water to form sugar molecules. Animals that consume plants metabolize the sugar molecules to obtain energy. Respiration, excretion, and decomposition all return carbon to the atmosphere or soil, thus completing the cycle.

Erosion, for example, releases carbon into the atmosphere slowly, whereas volcanic activity releases it quickly. Another way to quickly release carbon into the atmosphere is to burn fossil fuels in automobiles or power plants.

Answer:

2.4 × 10⁻⁶ M

Explanation:

Molar concentration = no of moles of solute (enzymes)/volume of solvent(cystosol)

Let V = volume of solvent = volume of cystosol = πd²h/4 where d = diameter of cell = 1.0 m and h = height of cell = 2.0 m

Concentration of enzymes, C = n/V where n = no of moles of enzymes

Also, n = m/M where m = mass of all enzymes and M = molecular weight of protein = 100,000

Note that the solvent for the enzymes is cystosol, since they are dissolved in it.

Density of cystosol,ρ = specific gravity of cystosol in g/cm³ = 1.20 g/cm³.

Now, ρ = m'/V where m = mass of cystosol and V = volume of cystosol

m' = ρV

m' = 1.20V

Given that 20 % of the cystosol is protein and all protein are enzymes, the mass of enzymes is thus m = 0.2m' = 0.2 × 1.20V = 0.24V

C = n/V

= m/MV

= 0.24V/100000V

= 2.4 × 10⁻⁶ mol/cm³

= 2.4 × 10⁻³ mol/dm³

= 2.4 × 10⁻³ M

This is the concentration of all the 1000 enzymes.

So, the concentration of one enzyme is 2.4 × 10⁻³/1000 M = 2.4 × 10⁻⁶ M

The ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

To find the ratio between 92 mL and 3.0 fl oz, we need to convert the units to a common measurement. Let's convert 3.0 fl oz to milliliters (mL).

1 fluid ounce (fl oz) is equal to approximately 29.5735 milliliters (mL).

Therefore, 3.0 fl oz is equal to 3.0 * 29.5735 = 88.72 mL (rounded to two decimal places).

Now we can express the ratio between 92 mL and 88.72 mL:

92 mL : 88.72 mL

Simplifying the ratio by dividing both sides by the greatest common divisor, we get:

46 : 44

So, the ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

Evolutionary theories are the flexible equivalent of species variability. To evaluate and support these theories, certain molecular clocks are used to know the relationship of species. These are done by considering the variations of every species' sequences of DNA. It is relevant to know the evidence that all living things contribute identical biochemical building blocks. Common ancestry and biological evolution is thereby supported by evidence regarding differences of structures. Homologous structures explains the same ancestry. Analogous structures, on the other hand, explains that the presence of identical features is the outcome of identical selective pressures.

100% of the offspring will be homozygous round in this cross.

What is a homozygous?

A homozygous round is an organism that has two identical copies (alleles) of a particular gene that codes for the trait "round." This means the organism will always express the round trait, regardless of the environment or the presence of other alleles.

This is because the round pea plant that is heterozygous still carries two copies of the round gene. When it is crossed with a homozygous round pea plant, all of the offspring will have two copies of the round gene, making them homozygous round.

The correct answer is: All of the above.

When a reaction has a negative reduction potential, it indicates that the reaction is more likely to undergo oxidation rather than reduction. Therefore, the reverse of the reaction would be an oxidation reaction.

Since the reverse reaction is an oxidation reaction, it would be spontaneous if the original reaction was spontaneous in the forward direction. Spontaneous reactions tend to occur naturally without the need for external energy input.

The products of the reduction reaction, in this case, would be the species that gained electrons. Therefore, they would have a tendency to lose electrons, making them more prone to undergo oxidation.

So, all the statements are true.

Answer:

Explanation: Binomial nomenclature is the scientific naming system used to identify and classify living organisms. It consists of two parts: the genus name and the species name, which are written in italics or underlined. The genus name is capitalized, while the species name is in lowercase.

To write someone's name using binomial nomenclature, you would need to first determine what species they belong to. This would typically involve identifying their kingdom, phylum, class, order, family, and genus, before arriving at the specific species.

For example, if the person in question is a human, their binomial nomenclature would be:

Genus: Homo

Species: sapiens

Therefore, their full binomial nomenclature would be written as "Homo sapiens".

It's important to note that binomial nomenclature is typically used to identify and classify living organisms, rather than individual people. However, it can be applied to humans for scientific or taxonomic purposes, such as in studies of human evolution or population genetics.
