Explanation:
The group of alleles that can be considered the gene pool of the moose population on Isle Royale would be all alleles of the moose in this population only.
A gene pool is the collection of all the genes (including alleles) found in a population or species that is capable of reproduction.
A big gene pool has a wide range of genetic diversity and is more resilient to environmental stresses. Due to a reduced gene pool caused by inbreeding, populations or species are less able to adapt to and endure environmental challenges.
The term "gene pool" refers to the entire gene pool found in interbreeding populations.

what is Kw?
what is the [H3)+] in pure water?
Answers
Answer:
In chemistry, Kw is called the dissociation constant or ionization constant of water.
The concentration of H3O+ ions in pure water at 25°C is 10^-7 M . This means that there are 10^-7 M of H3O+ ions in pure water.
Explanation:
Kw is the ion product constant for water, which is the product of the concentrations of hydrogen ions (H+) and hydroxide ions (OH-) in water at a given temperature. At 25°C, Kw has a value of 1.0 x 10^-14. This means that for any aqueous solution at 25°C, the product of the concentrations of H+ and OH- will always equal 1.0 x 10^-14.
In pure water at 25°C, the concentration of H+ ions (also called hydronium ions or H3O+) is equal to the concentration of OH- ions. This is because pure water is neutral, meaning that it has an equal number of positive and negative ions. Therefore, the concentration of H3O+ in pure water at 25°C is also 1.0 x 10^-7 M.
Describe the relationship between particle motion, temperature, and thermal energy.
Answers
Answer:
The average energy of motion of particles in a substance is its kinetic energy. Therefore, temperature is the measure of the average kinetic energy of the particles of a substance. The thermal energy of the substance is the total energy of the substance.
Explanation:
We want to explain the relationship between particle motion, temperature, and thermal energy.
First, let's explain the relationship between thermal energy and temperature.
When we have a given object, as we give it thermal energy (there are different ways, like radiation, conduction, etc) the temperature of the object increases.
So we can say that the temperature is a measure of the stored thermal energy.
Now, the relation between temperature and particle motion is more interesting.
As we increase the temperature of a given object, the increase in energy (again, the temperature is related to energy) comes from an increase in the kinetic energy of the particles that make the object.
Thus, when we increase the temperature of something, the particles that conform it move more (remember that the kinetic energy is related to the velocity of the particles). This is why we usually see an increase in the volume when we heat up something.
And also this is why most elements have more volume in the gas phase than in the liquid phase, for example.
These are the relations between thermal energy, temperature and particle motion.

What is physical weathering? (1 point)A. the building up of rock that has been brought from other placesB. the movement of rock from one place to anotherC. the transformation of rocks into some other type of materialsD. the breaking of rock into smaller pieces from nonchemical processes
Answers
Mechanical weathering is also called as physical weathering. It breaks rocks into smaller pieces. It is a process that changes solid rock into sediments. That means the rock has changed physically without changing its composition. The smaller pieces have the same minerals as the original rock. One way that rocks can be broken apart into smaller pieces is abrasion where one rock bumps against another rock.
Sometimes, a mother who is affected with a mitochondrial disease will have an unaffected child. Which of the following could explain this observation?
A. The phenotype could be affected by nuclear genes, which could differ among children.
B. Environmental factors (such as taking antibiotics) could affect expression of the phenotype.
C. The affected mother could be heteroplasmic.
D. One or more of the children could inherit the majority of their mitochondria from an unaffected father.
Answers
C. The affected mother could be heteroblastic . The chance of producing an unaffected child increases if the egg has a higher proportion of normal DNA.
What is Phenotype?
Phenotype refers to the observable physical, biochemical, and behavioral characteristics of an organism, which are determined by the interaction of its genotype (genetic makeup) with the environment. It is the expression of the genes of an individual, which can be influenced by various factors such as the individual's developmental history, environmental factors, and lifestyle.
Mitochondrial diseases are caused by mutations in mitochondrial DNA ( DNA). Inheritance of DNA follows a maternal pattern, meaning that the DNA is passed down from the mother to her offspring. In some cases, a mother who has a mitochondrial disease may have some unaffected children. One possible explanation for this is that the mother is heteroblastic, meaning that she has a mixture of normal and mutant DNA in her cells. When she produces eggs, the distribution of normal and mutant DNA in each egg can vary, and this can result in some eggs having predominantly normal DNA, while others have predominantly mutant DNA.

Look at the map below. The mountains in the Pinnacles National Monument and the mountains at Tejon Pass were once located next to each other and
a part of the same mountain range Now however, they are separated by over 240 kilometers Explain how the mountains at Pinnacles National Monument
and the mountains at Tejon Pass became separated from each other koi
Answers
Answer:
The mountains at Pinnacles National Monument and the mountains at Tejon Pass became separated from each other after suffering a transforming process, in which plates slid laterally against each other along the fault.
Explanation:
The tectonic plates theory is based on the continual movements of the crust and might explain the movement of the different plates, and their directions and interactions.
Plates are limited by three different ridges or borders that differ in the type of movement they produce.
Divergent limits: two plates get separated.Convergent limits: These movements occur when two plates collide.Transforming limits refer to geological structures related to the seafloor expansion and associated in general with the oceanic ridge, although they might also occur in the continental plate. These limits are known as geological faults, where no rocky material is either destroyed or formed. When the plates move and produce a displacement of one transforming limits from side to side, earthquakes occur. The movement breaks the crust and originates pronounced fractures. The San Andrés fault is an example of these plate ridges.A subduction process first originated all the mountains. This process took a lot of time and it in different stages. But once it concluded, a new process followed the first one. The transforming process, which occurred when the Pacific plate collided against the occidental ridge of the North American plate until it broke along the tension line. This process involves a movement of plates in which they slide laterally against the others along a line known as a fault.
As you can see on the map, the Pinnacles National Monument and the mountains at Tejon Pass are placed on opposite sides of the fault line. At first, they were together, and then by the transforming process, the plates moved along the fault separating them.

Answers
Answer A is the right choice. A specific tRNA molecule's anticodon complements the corresponding mRNA codon.
The mRNA molecule's matching codon and the anticodon of the tRNA are complementary. As a result, complementary base pairing allows the tRNA to bind to the mRNA codon. The appropriate mRNA codon and the tRNA anticodon are hence complementary. A trinucleotide sequence called an anticodon is found at one end of a transfer RNA (tRNA) molecule and is complementary to a corresponding codon in an mRNA sequence.
The tRNA molecules are in charge of pairing amino acids with the proper codons in the mRNA. Each tRNA molecule has two separate ends; one of them attaches to a particular amino acid, while the other one binds to the appropriate mRNA codon.
Therefore, we might conclude that Answer A is the best option. The complementary mRNA codon of a particular tRNA molecule is its anticodon.

Answers
Answer:
Jesus made every one evalution is false
When Charles Darwin introduced the theory of evolution through natural selection 158 years ago, the scientists of the day argued over it fiercely, but the massing evidence from paleontology, genetics, zoology, molecular biology and other fields gradually established evolution's truth beyond reasonable doubt. Today that battle has been won everywhere—except in the public imagination. Embarrassingly, in the 21st century, in the most scientifically advanced nation the world has ever known, creationists can still persuade politicians, judges and ordinary citizens that evolution is a flawed, poorly supported fantasy. They lobby for creationist ideas such as “intelligent design” to be taught as alternatives to evolution in science classrooms. When this article first went to press in 2002, the Ohio Board of Education was debating whether to mandate such a change. Prominent antievolutionists of the day, such as Philip E. Johnson, a law professor at the University of California, Berkeley, and author of Darwin on Trial, admitted that they intended for intelligent-design theory to serve as a “wedge” for reopening science classrooms to discussions of God.
The good news is that in 2005 the landmark legal case Kitzmiller v. Dover in Harrisburg, Pa., set binding precedent that the teaching of intelligent design in U.S. public schools is unconstitutional because the idea is fundamentally religious, not scientific. The bad news is that in response, creationists have reinvented their movement and pressed on. When they lost the ability to claim that creationist ideas are valid science, they switched to arguing that they were only supporting “academic freedom.” Worse, to further obscure the religious roots of their resistance, they now push for “critical analysis” of climate change, cloning research and other scientific endeavors that they paint as culturally oppressive.Explanation:

Answer:
Cancer can develop anywhere in the body. It starts when cells grow out of control and crowd out normal cells. This makes it hard for your body to work the way it should.
For many people, cancer can be treated successfully. In fact, more people than ever before lead full lives after cancer treatment. The cells in our bodies all have certain jobs to do. Normal cells divide in an orderly way. They die when they are worn out or damaged, and new cells take their place. In cancer, the cells keep on growing and making new cells. They crowd out normal cells. This causes problems in the part of the body where the cancer started. They can also spread to other parts of the body.
