Answer:
Mining in the Appalachians has caused debris and harmful chemicals to land in the local waterways. The large amount of waste and dirt has also changed the course of the canals.

Which of your plants was a dicot? Which was a monocot? How could you tell?
PLANTS :
Sunflower
Pansies
HYdrangeas
Answer: Sunflower : Dicot, Pansies : Dicot, Hydrangeas: Monocots.
Explanation:
Within the plant kingdom, seed-bearing plants are divided into gymnosperms and angiosperms. Angiosperms are the group of plants that have flowers, within which we have monocotyledons and dicotyledons or eudicotyledons. A cotyledon is a leaf-like structure found on the seed so it is an embryonic leaf. Its function is to absorb nutrients in the seed until it develops true leaves that will allow to perform photosynthesis.
Monocotyledons are flowering plants whose seeds have one cotyledon. Dicotyledons are flowering plants whose seeds have two lateral cotyledons. Both monocot and dicot seeds have an embryo plant, a coat, and is able to store nutrients.
The true leaves monocots will be thin and long, while dicot leaves will be broad. Another characteristic is that the major veins of monocots are parallel and stripe-like while the dicot veins branch out. Also, monocots have flower parts in multiples of 3 while dicot flower parts are produced in multiples of 4 and 5. Roots in monocots sprout from many parts of the plant while dicot roots develop only from the radicle, which is the first part of a seedling to emerge during germination. This means monocots do not have secondary growth and dicots usually produce secondary growth.
Sunflower : Dicot, because it shows two cotyledons when the seed germinates.Pansies : Dicot, because it has 5 leaves. Hydrangeas: Monocots, they only have one cotyledon.A student is performing an investigation using rennin and milk. Rennin is an enzyme that can solidify milk. She
puts milk in three test tubes with rennin and places the tests tubes in water baths at different temperatures
of 32°F, 98°F, and 212°F. She notices the rennin enzymes become denatured at 212°F and do not solidify
the milk. Which statement correctly describes the effect of the denatured enzymes?
A. Denatured enzymes are slowly active.
B. Denatured enzymes are no longer active
C. Denatured enzymes reverse the reaction.
D. Denatured enzymes speed up the reaction.
Answer:
The correct answer is - option B. denatured enzymes are no longer active.
Explanation:
Denaturation of the enzymes or proteins results in changes in their original structure which ultimately results in the loss of their particular functions. The denaturation of proteins or enzymes takes place due to extreme temperature or pH which leads to a change in the active site of an enzyme.
Due to this change, the substrate will no longer fit in the active site and become inactive as enzymes work together with the substrate and the active site is the essential part of the enzyme for its activity. In this case, this is condition takes place which makes it denatured at 212 degrees F.

Which abiotic factor in tropical forests do boreal forests lack?
Answer:
warm temperature
Explanation:
I cannot see the choices in your image. I can only see choice A, which is "soil."
"Abiotic factors" are part of the ecosystem that don't have life. However, they have an impact on the life of the biotic factors (living organisms) in the environment. Examples of abiotic factors are: sunlight, temperature, climate, soil, humidity, wind, etc.
"Boreal forests" are abundant on the Earth's Northern Hemisphere. The climate here is generally cold, which doesn't allow some trees to survive. It is totally opposite to the warm temperature and high humidity that you can feel in the "tropical forests." Such factors allow many plants and animals to survive.
Clearly, the boreal forests lack the "warm temperature" that the tropical forests have.

Why would looking for the persons responsible for sneaking endangered species (rare birds, for example) into the United States be considered a job for a forensic scientist
Answer:
Forensic scientists are able to find the answer.
Explanation:
The persons responsible for sneaking endangered species into the United States be considered a job for a forensic scientist because forensic scientist is able to find out the persons. Forensic scientist are the investigators who collect evidences from the crime scene and leads to the person who commit crime. So the forensic scientist is the only person who find out the persons responsible for sneaking endangered species.

Explanation:
Explain what factors can lead to genetic
variation within a population.
Answer:
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
Hope this helped :)
Species that only use asexual reproduction only develop new genetic combinations through the process of mutation.
A. True
B. False
Yes, this is true, because in asexual reproduction there is very little genetic diversity, except in the case of a mutation.

A, B and D
Explanation:
In a study of a muscle disorder, several families exhibited vision problems, muscle weakness, and deafness. Analysis of the mtDNA (mitochondrial DNA) from affected persons in these families was analyzed using PCR (polymerase chain reaction) and gel electrophoresis. The unaffected samples were collected from multiple mitochondria, whereas each affected sample was collected from a single mitochondrion. What can you conclude about the affected individuals' mitochondrial DNA?
A. There is no common deletion.
B. There is one common deletion.
C. There are two common deletions.
D. There are more than two common deletions.
Answer:
A. There is no common deletion.
Explanation:
The correct answer to the given question is the option A. There is no common deletion.
In the study of the muscle disorder, the samples taken and the effects observed concludes that there was no common deletion among the analysed families and their mitochondrial DNA.
Some researchers estimate that the mutation rate for any given gene (or its DNA) in certain strains of bacteria is about 108. This means that one error or mutation in a given gene is introduced for every 100-million cell divisions. What can cause mistakes in replication

If the DNA integrates properly into the germ cells, the adult fly will contain _________________ that contain _____________________________. After mating, these flies can then produce progeny that will contain ______________________.
Answer:
Five pairs of autosomal and one pair of heterochromatic sex chromosomes.
Explanation:
The adult fly will contain 12 number of chromosomes that contain five pairs of autosomal and one pair of heterochromatic sex chromosomes. After mating, these flies can then produce progeny that will contain diploid i. e. double number of chromosome. One set of half chromosomes from the male fly while the other half chromosomes comes from female fly so the offspring will receive double number of chromosomes.

The diagram compares diffusion of sugar molecules and osmosis. Explain the difference between osmosis and diffusion in cells
Answer:
What is the difference between osmosis and diffusion? Osmosis is the movement of water molecules through the cell. Diffusion is the movement of molecules, such as oxygen, in and out of a cell. The process by which water molecules are able to diffuse through the cell membrane.
Explanation:
Diffusion and osmosis involves the movement of materials from one region another. The main difference between osmosis and diffusion is that osmosis requires a semi permeable membrane.
The movement of materials always occur in cells. This movement could occur by;
Active transportOsmosisdiffusionThe difference between osmosis and diffusion is that, diffusion does not involve a semi permeable membrane.
A semi permeable membrane is a membrane that is selectively permeable to materials. It allows some materials to pass and does not allow other materials to pass. We can see the semi permeable membrane as the structure in the osmosis diagram that separates the two regions.
Diffusion does not require the use of a semi permeable membrane.
