bal Coal mining has significant environmental impacts. As it usually requires the removall of massive amounts of top soil, it can lead to erosion, pollution (through dust fall-out of particulate matter) and loss of habitat. The use of coal is also problematic, because burning coal emits carcinogencic and toxic substances to land, air and water. Coal is also a solid fossil fuel, but it is the dirtiest of all, being the single largest source of global temperature rise.

How does the temperature of water change if you heat it after it has alread
reached the boiling point?
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.

a short pea plant that is heterozygous for flower colour is crossed with a homozygous tall pea plant that is also heterozygous for a flower colour. determine the genotypes of the plant. what gametes can the plants produce
The genotypes of the plant are,
Short Plant + Heterozygous Flower Color- ttYy
Homozygous Tall Plant + Heterozygous Flower Color- TTYy
The gametes for short plant with heterozygous for flower color are tY, and ty. Where gametes for homozygous tall plant with heterozygous for flower color are TY, and Ty.
T- Tall height allele, t- short height allele; Y/y- Flower color allele.
Heterozygous Allele- A gene can exist in two or more different forms, known as alleles, and they can all be present at the same location, or locus, on a chromosome. The term "heterozygous" describes the presence of several alleles for a given characteristic.
Homozygous Allele- In terms of genetics, being homozygous means have inherited the same alleles (versions) of a genetic marker from both biological parents. A person who possesses two identical copies of a genetic marker is said to be homozygous for that marker.

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.
Is Vitamin B12 important?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.

A student decided to find the density of her house key to try and identify the type of metal from which it is made. She found the volume of the key to be 5 mL and the mass to be 39.5 g. Using the chart above, from which type of metal is the key made?
Going by the density of the key which is 7.9 g/mL, the key is likely made from iron.
DensityThe 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.

what are the two processes in meiosis that create genetic differences among cells?
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.
What are recombination and independent assortment?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.

How might you model the relationship between a tomato plant and the hornworm catepillar?
Answer:
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.

Every enzyme has a different sequence(order) of amino acids, so every enzyme has a different________.
- temperature
- shape
- activation energy
- specific heat
Every enzyme has a different sequence (order) of amino acids, so every enzyme has a different shape (Option 2).
What does dictate enzyme structure?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.

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.
