Answer:

Hardness is one of the better properties of minerals to use for identifying a mineral. Hardness is a measure of the mineral's resistance to scratching. ... Softer minerals can be scratched by harder minerals because the forces that hold the crystals together are weaker and can be broken by the harder mineral.

How does coal create a negative impact to the environment?
telo118 [61]
Coal creates a negative impact on the environment because it contains sulfur and other harmful elements. When you burn coal these elements are then released into the air. And it can cause air pollution and health dangers as it releases a lot of carbon dioxide.

1.The Punnett square above shows a cross between two sweet pea plants in Mendel's
jenyasd209 [6]
1) 75% purple flowered and 25% white flowered. If you complete the punnett square, you'll see the combinations are PP, Pp, Pp, and pp. The capital P is dominant (purple), so you know that 3/4 combinations will be purple flowers.

2) 50%. There is a 50% chance Grace will have Huntington's disease because since the disease is dominant, it is capital letter H. When you make a punnett square, you'll see the combinations are Hh, Hh, hh, and hh. There is a 50% chance Grace will have the Hh combination.

3) Protein. Protein is the only bio-molecule out of the 4 options, and the diagram shows a protein being made.

4) Transcription. Transcription is when the genetic message from DNA is transcripted onto mRNA.

You measure the mass of an apple using a balance.you get these tree measurements:
kiruha [24]
In a Biology scientific report there will always be factors that change even if its by a little bit. In order to increase the “Reliability” of your conclusion or experiment you are required to do your experiment multiple times. Obviously in this case things such as the scale sensitivity will change according to the scale you use as well as if it is accurately set to scale but usually you will get a change in answer. The other thing you need to remember is that when the apple was originally measured they used another measuring tool to you therefore altering your answer ❤️

Lilit [14]

Answer:

Speciation results in biodiversity.

Explanation:

This phylogenic tree shows the changes in bacterial species from the ancestral species to the most current split in the modern classification system. This tree supports the theory that <u>speciation results in biodiversity</u>. As we know speciation is the terminal source of the latest species, in a similar way, that modification is the terminal source of genetic divergence within species (and extirpation is comparable to lack of alleles). Inequities in the movements of speciation are therefore expected to provide large scale biodiversity exemplars.
