Answer:High pH levels (9-14) can harm fish by denaturing cellular membranes. Changes in pH can also affect aquatic life indirectly by altering other aspects of water chemistry. Low pH levels accelerate the release of metals from rocks or sediments in the stream.

Make a list of ecological consequences that you can infer have occurred on Guam due to the introduction of the invasive (nonnative) brown tree snake
Answer:
There are many ecological consequences that could have, or already have, occurred.
Invasive species are notorious for the chaos and destruction they bring upon ecosystems. As an ecosystem is perfectly balanced, a new factor causes this to become askew. The brown tree snake may hunt prey that is the main diet of a different species there. This may cause both the prey and native species to begin to die off, and if the prey goes extinct because of this, the native species will as well, unless they somehow adapt. Not only this, the brown tree snake is known for causing frequent power outages by climbing on electrical wires. They are the cause of the loss of 9 out of 11 forest birds native to Coco's island. They are causing a serious decline in birds, rodents, lizards, and even bats in Guam.

I’m at the beginning of earth’s timeline, but at the end of life’s start. I was there when a T-rex began, but in the middle of it’s asteroid end. What am I?
I believee it's the Cretaceous Period?
All of the dinosaur periods are at the start of Earth's timeline, and "the end of life's start" suggests the end of dinosaurs, meaning, when the asteroid hit. So it's probably one of the Mesozoic periods.
The T-rex first appeared in the Cretaceous Period, and the asteroid hit somewhat during middle of the Cretaceous Period.
I hope I'm right, and I hope this helps!
Which of the following most likely indicates that a chemical change has
happened?
A. A plate breaks when it falls to the floor.
B. There's a loud sound when a jet airplane starts its engines.
C. An icicle melts in the sun.
D. A can is crushed when it is stepped on.
Answer:
Option B
Explanation:
A plate breaking when falling to the floor would be a physical change, not chemical, as what the plate is created from would not change.
An icicle melting in the sun would be a physical change, as an icicle is frozen water, and after melting it would be normal water.
A can being crushed is still just a physical change, as the material making the can(typically aluminum) has not changed.
When a jet airplane starts its engines, fuel is combusted, creating energy for the engines to start. This would create the loud noise. As fuel is combusted, it turns into different things, henceforth the sound would imply a chemical change has occurred.

Explanation:
which part of the amino acid most likely contributes to the hydrophobic behavior if this region in the polypeptide
Answer:
This question is incomplete
Explanation:
This question is incomplete, however, the side chain is usually the part of an amino acid that is either hydrophilic or hydrophobic in nature. When the side chain has little or no polarity (i.e they lack the ability to interact with highly polar water molecules), the amino acid exhibits hydrophobic properties. Hydrophobic (water-fearing) substances are substances that do not interact/dissolve in water.

What is natural breeding?
Answer:
Natural breeding refers to the random mating that occurs between two individuals of the same species. Conversely, selective breeding has been performed for centuries by humans hoping to produce offspring with desirable traits.

Density describes how much mass is contained in a certain volume. Knowing how far apart molecules are in each state, which best ranks solids, liquids, and gasses from least dense to most dense?
Gasses are denser than liquids.
Liquids are denser than solids.
Gasses are less dense than solids.
Solids are less dense than liquids.
Solids have a high density because the particles are very close together, a liquid mass is slightly less dense, and a gas mass has a very low density with the particles much further apart.
What Is a Density?The measure of how densely a material is packed together is called density. As the mass per unit volume, it has that definition. Density Formula: D or Density Symbol: D ρ = m/V where the object's mass (m), its volume (V), and its density () are all given.
Generally, gases are less dense than liquids, while liquids are less dense than solids. This is due to the fact that solids have tightly packed particles, liquids have materials in which particles can slide around, and gases have free-moving particles.
Therefore, Gasses are less dense than solids because particles are far away from each other in gas masses.

what is the connection between mitosis and cancer
Answer:
Checkpoints
Explanation:
Cancer is essentially a disease of mitosis - the normal 'checkpoints' regulating mitosis are ignored or overridden by the cancer cell. Cancer begins when a single cell is transformed, or converted from a normal cell to a cancer cell.
Answer:
Cancer: mitosis out of control
Mitosis is closely controlled by the genes inside every cell. Sometimes this control can go wrong. If that happens in just a single cell, it can replicate itself to make new cells that are also out of control. These are cancer cells

SOMEONE HELP!!! ITS FOR A MAJOR GRADE!!
"Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits. He recognized the mathematical patterns of inheritance from one generation to the next."
Through his work, Mendel published his experiments to explain his findings.
What did his laws of inheritance state?
SELECT ALL THAT APPLY
A.Parental genes are randomly separated from the sex cells so that sex cells contain only one gene of the pair.
B.Each trait of an organism can contain multiple alleles of that trait.
C.Organisms with alternate forms of a gene will express the dominant form of the gene.
D.The inheritance of one trait is not dependent on the inheritance of another.
E.Genes can be transferred from the parent generation directly to the offspring based on the environmental factors surrounding the offspring.
