Going by the density of the key which is 7.9 g/mL, the key is likely made from iron.

The density of a substance is the ratio of the mass of the substance and of its volume.

The density of a substance can be mathematically expressed as:

Density = mass/volume.

Considering the key in question whose volume is 5 mL and mass is 39.5 g. The density can be determined as:

Density of the key = 39.5 /5

                                 = 7.9 g/mL

In order to determine the nature of the metal that the key was made from, one would need to check the table of density of metals. Any metal whose density corresponds with, or is close to 7.9 g/mL would be the metal that the key is made from.

From a chart of density, the metal with a density of 7.9 g/mL is iron.

In other words, the key must have been made from iron.

ATP → ADP + P is an example of an endergonic reaction, because there is an output  of the energy.

An endergonic reaction is one that calls for free electricity to proceed. An example of an endergonic response of biological hobby is photosynthesis. Photosynthetic organisms conduct this response by using using sun photons to drive the discount of carbon dioxide to glucose and the oxidation of water to oxygen.

Within the exergonic response, the reactants are at a higher unfastened power degree than the goods reaction is going energetically downhill. In the endergonic response response, the reactants are at a decrease loose power stage than the products response goes energetically uphill.

The endergonic reactions of photosynthesis and chemosynthesis allow creatures at the bottom of the energy pyramid to live to tell the tale and to feed organisms like ourselves, who get their strength by means of breaking down sugars and fats to free up that stored power.

Every enzyme has a different sequence (order) of amino acids, so every enzyme has a different shape (Option 2).

The enzyme structure depends on the linear sequence of their subunits, which are represented by amino acids. These subunits (amino acids) are linked together by peptide bonds to form the primary structure of proteins, which associates different amino acids in the chain to form structures of higher order (i.e., secondary, tertiary and quaternary structures)

Therefore, we can conclude that enzyme structure is due to the linear sequence of amino acids that are linked by peptide bonds.

When someone is vitamin B12 deficient, one of the reasons could be that the person's dies does not contain proper amount of vitamin B12.

A crucial B vitamin is vitamin B12. It is essential for the health of the brain, the generation of red blood cells, and nerve tissue. Vitamin B12 can also be called as cobalamin.

When the body cannot absorb enough vitamin B12, a deficiency or an insufficiency can develop. If left untreated, this can cause a variety of symptoms, including the development of irreparable brain problems.

Like every other B vitamin, this vitamin B12 is a water-soluble vitamin. This implies that it can dissolve in liquid and circulate through the body.

Up to four years’ worth of vitamin B12 can be stored by the body, and any extra or undesired amounts can be excreted in the urine.

Answer:

independent assortment during anaphase and crossing over during prophase

Explanation:

genetic material is swapped during crossing over

chromosomes from either mother or father could be put into any gamete during independent assortment

The two processes in meiosis that create genetic differences among cells are independent assortment and recombination.

DNA fragments are broken and recombined during the recombination process to create novel allele combinations. The genetic variation that results from this recombination process at the gene level reflects variations in the DNA sequences of various species.

Recombinant and novel gene combinations are produced by the independent collection of genes.

The connected genes do not demonstrate independent assortment, since they are inherited together. More parental types and fewer recombinant are created because connected genes lack independent assortment.

Thus, the two processes are independent assortment and recombination.

Explanation:

The temperature of water does not change.

This is because when water is heated to its boiling point of 100 degrees Celsius, it usually takes more energy to turn a liquid into a gas, so the extra heat helps with that conversion. The temperature of water, even if it reaches its boiling point, does not change until all the water evaporates into the atmosphere. Depending on the type of container, the temperature will rise when the water runs out.

Parasitism.

Explanation:

The relationship between a tomato plant and the hornworm caterpillar is parasitism because parasitism is a type of symbiotic relationship in which one organism get benefits and the other get harmed. We know that hornworm caterpillar feed on leaves and destroy the tomato crop. So it gets nutrients from tomato plant and the tomato plant is negatively affected. The input of this system is the vegetative part of tomato plant while the output is the conversion of hornworm caterpillar into a moth.

The complete statement is given as "The distance between Earth and mars is 2.25Km. When converting using the conversion factor 1 AU=1.5 x 10 power 8km, the distance between the planets is 1.5 AU."

This is further explained below.

Generally, The astronomical unit is a measure of length that is equal to 8.3 light minutes or 150 million kilometers. It is approximately equivalent to the distance that separates the Earth and the Sun.

In conclusion, The distance from Earth to Mars is about 2.25 kilometers. Using the conversion factor that one AU is equal to 1.5 x 108 kilometers, the distance that separates the planets is calculated to be 1.5 AU.

The light-year and the AU are not interchangeable units of measurement. The distance traveled by light throughout one year is about 9.5 x 1012 kilometers.

The notion that we evolved from modern apes is wrong but we have evidence that humans evolved from apelike ancestors.

With time, genetic change can change the overall way of life of a specie like eating behavior, growth, and place of living. Human evolution took place when new genetic changes occur in the ancestor's populations which favor new abilities in that organisms to adapt to environmental change. Scientific evidence indicates that the physical and behavioral traits that are shared by all people come from apelike ancestors which evolved about six million years. One of the earliest defining human traits is bipedalism i.e. the ability to walk on two legs was evolved over 4 million years ago.

So we can conclude that hominids evolved because of the genetic change that occurs with time due to environmental change. We have many evidence that humans evolved from apelike ancestors due to environmental change.

In order to prepare 1 mL 80 mg/mL, 1 mL 60 mg/mL, 1 mL 40 mg/mL, and 1 mL 20 mg/mL glucose solution from a 100 mg/mL stock solution, 0.8 mL, 0.6 mL, 0.4 mL, and 0.2 mL of the stock will be taking and diluted with 0.2 mL, 0.4 mL, 0.6 mL, and 0.8 mL water resectively.

The dilution principle states that the number of moles of solute in the original stock before dilution must be equal to the number of moles of solute in the diluted stock.

This principle is mathematically expressed as: m1v1 = m2v2

Where: m1 and v1 = molarity and volume before dilution

           m2 and v2 = molarity and volume after dilution.

In this case, the stock is 100 mg/ml.

       v1 = v2m2/m1

           = 1x80/100

            = 0.8 mL

This means that 0.8 mL of the stock will be taken and diluted with 0.2 mL of water to make 1 mL, 80 mg/mL solution.

        v1 = 1 x 60/100

              = 0.6 mL

This means that 0.6 mL of the stock will be taken and diluted with 0.4 mL of water to make 1 mL, 60 mg/mL solution.

        v1 = 1 x 40/100

              = 0.4 mL

This means that 0.4 mL of the stock will be taken and diluted with 0.6 mL of water to make 1 mL, 40 mg/mL solution.

        v1 = 1 x 20/100

              = 0.2 mL

This means that 0.2 mL of the stock will be taken and diluted with 0.8 mL of water to make 1 mL, 20 mg/mL solution.
