Which subatomic particle determines an element's atomic number?
Answer: protons
Explanation: atoms of each element contain a characteristic number of protons
Answer:
the answer is protons
Explanation: Atoms of each element contain a characteristic number of protons. In fact, the number of protons determines what atom we are looking at (e.g., all atoms with six protons are carbon atoms); the number of protons in an atom is called the atomic number. In contrast, the number of neutrons for a given element can vary.
The Devils Hole pupfish is one of the world's rarest fishes, spending most of its life in the top few meters of very warm waters of a cavern located in the middle of the Mojave Desert. Devils Hole,
a geologic pool, is the only naturally occurring habitat for the endangered Devils Hole pupfish. This fish's habitat is one of the smallest natural ranges known for any vertebrate. Devils Hole is an
extreme environment, with water temperatures and dissolved oxygen concentrations near the lethal limits for most fish species.
Which of the following statements best explains why the Devils Hole pupfish are able to live in this environment?
Answer:
Thermal invasive
Explanation:
Devils Hole pupfish can live in this environment because they have adapted genes, which offer resistance to their bodies to the harsh environment where they live.
We can come to this answer because:
A living being can only live in an inhospitable environment if its organism allows for an adaptation.In this case, we can say that Devils Hole pupfish had a population with different genetic compositions, where some had genes adapted to this environment and others did not have these genes.Devils Hole pupfish that didn't have the adapted genes didn't resist the environment and died.The Devils Hole pupfish that possessed the genes survived and passed those genes on to their descendants.In this case, Devils Hole pupfish that received the genes adapted to the environment developed resistance that allows them to live amidst extreme resources.

Which statement best explains the importance of enzymes lowering the activation energy necessary for reactions to take place?
a Reactions that require less energy to begin are able to occur more quickly.
b Reactions produce heat, causing the chemical bonds to become strong.
c Reactions are able to proceed slowly to maintain the metabolism of the cells.
d Reactions requiring less energy are able to produce less product.
Answer:
A
Explanation:
because a enzyme simply speeds up a reaction and only does that by pressure and stress not by doing chemical changes
The statement which best explains the importance of enzymes lowering the activation energy necessary for chemical reactions to take place is: A. Reactions that require less energy to begin are able to occur more quickly.
A chemical reaction can be defined as a chemical process which mainly involves the continuous transformation or rearrangement of the ionic, atomic or molecular structure of a chemical element through a break down and formation of chemical bonds, in order to produce a new chemical compound.
As a general rule, the activation energy of a chemical reaction must first of all be reached by its combining chemical elements (reactants) before it can start or begin.
An enzyme can be defined as a biological catalyst that is used to speed up (increase) or catalyze (accelerate) the rate of a chemical reaction, by lowering (decreasing) the activation energy of its constituent chemical elements (reactants).
Hence, a chemical reaction that only require less energy to begin (start) are able to occur more quickly before those that require high energy.
In conclusion, the activation energy of a chemical reaction should be lowered in order for it to occur or take place fast (quickly) enough over a short period of time.

The components that make up the genetic code are common to all organisms. If a segment of a gene contains 27 nucleotides, none of which are stop or starts codons, how many amino acids does this segment code for?
Answer:
9 amino acids
Explanation:
A segment of a gene that has 27 nucleotides will code for 9 amino acids.
Each codon on the gene potentially represents an amino acid and a codon is made up of 3 nucleotides each. Hence, in order to find out the total number of amino acids that a gene segment with 27 nucleotides can code for, the number of nucleotides should be divided by 3.
number of amino acids = number of nucleotides/3
27/3 = 9 codons/amino acids

Which feature do plants have that provide structure and form?
Answer:
Plants have a cell wall which gives the plant structure. The cell wall is made of cellulose.
Explanation:
Answer: plants have an internal skeleton of bones
Explanation:
The oceans have become increasingly acidic in recent years as the water absorbs more and more carbon dioxide
from the atmosphere. This increased acidity interferes with the ability of corals to maintain their skeletons. In
addition, an increase in water temperatures worldwide is causing coral bleaching, another condition that threatens
the health of coral reefs.
Based on this information, which of the following would most improve the health of coral reefs?
Reducing the use of fossil fuels since they emit CO2 that reacts in water
CO2+H2O-->H2CO3
The following would most improve the health of coral reefs is reducing the use of fossil fuels.
What kills corals?One of the biggest threats to coral reefs is the so-called "coral bleaching", a process that leads to the death of hundreds of corals around the world. The phenomenon occurs when the temperature of the water increases, due to natural causes, such as El Niño, or caused by man, such as global warming.
Scientists have created a device that innovates the technique of transplanting corals from the recovery of fragments with tissue loss. The device works as a kind of cradle, where the fragments are kept until they recover and grow.

does aerobic and anaerobic respiration have the same number of carbons, hydrogens and oxygens? Explain.
The fundamental difference between aerobic and anaerobic respiration is the usage of oxygen in the process of cellular respiration. Aerobic respiration, as the name suggests, is the process of producing the energy required by cells using oxygen. The by-product of this process produces carbon dioxide along with ATP – the energy currency of the cells. Anaerobic respiration is similar to aerobic respiration.

How is torque related to force?
Answer:
Torque is a measure of the force that can cause an object to rotate about an axis. Just as force is what causes an object to accelerate in linear kinematics, torque is what causes an object to acquire angular acceleration.
Fun Fact - Johnny Appleseed’s fruits weren’t for eating
Yes, there was a real John Chapman who planted thousands of apple trees on U.S. soil. But the apples on those trees were much more bitter than the ones you’d find in the supermarket today. “Johnny Appleseed” didn’t expect his fruits to be eaten whole, but rather made into hard apple cider.
