Answer:
Another allele frequency = 17%
Explanation:
Given:
Allele A has a frequency = 83 percent
Find:
Another allele frequency
Computation:
Sum of percent = 100%
So,
Another allele frequency = 100% - 83%
Another allele frequency = 17%
Most igneous activity takes place?
Answer:
under the ground in volcanoes
Explanation:
There are some volcanically active spots that are in the middle of a tectonic plate.
The interior of the Earth is hot, while the surface or crust of the planet is cold. Between these layers are areas of molten rock. These molten rocks are less dense, so they easily break through cracks in the Earth's crust.
Magma is molten rock and is found beneath Korea. Beneath the volcano, in the underground spaces, magma accumulates.

Roller coasters, with their twists, turns, and loops, seem to defy everything we know about how objects move. Roller coaster designers use Newton's laws to
push people past their usual limits. Which statement identifies Newton's Law of Motion with the correct justification of that law? (DOK 2, AKS 8b)
OA Newton's first law is the law of inertia. Since an object at rest stays at rest, all roller coasters have to be pushed or pulled to get started.
OB. Newton's first law is the law of force and acceleration. Since the rollercoaster is so massive, it will require more force to accelerate
OC. Newton's third law of action-reaction states that for every action, there is an equal and opposite reaction. This means that as you push down on the
seat, the seat does not push back on you with an equal force.
OD. Newton's second law is the law of force and acceleration. Since the rollercoaster is so massive, it will require less force to accelerate.

Answer:
limiting factors
Explanation:
The ecological optimum represents the value of the factors within the ecological valence at which the life processes of a species take place best. The upper and lower limits of an ecological valence are its maximum and minimum. Beyond these limits, physiological processes are interrupted and death occurs.
Is hemoglobin a hormone?
Answer:
I'm really sorry it is not.
A new hormone called erythroferrone, which regulates the iron supply needed for red blood-cell production, has been discovered by researchers. Iron is an essential functional component of hemoglobin.
Hemoglobin is the iron-containing protein compound within red blood cells that carries oxygen throughout the body. It is made up of heme, which is the iron-containing portion, and globin chains, which are proteins. The globin protein consists of chains of amino acids, the "building blocks" of proteins.

A graph of KE vs the mass of an object is ___
Answer:
A non linear relationship
Explanation:
hope this helps.
A graph of KE vs the mass of an object is a non-linear relationship.
What are graphs?Graphs are the mathematical representations of numbers and data on graph paper. They are an easy way to see the changes in the data over time.
In nonlinear relationships, changes in any of the inputs are not proportionate to changes in the output. A nonlinear relationship produces a curve when it is plotted on a graph, whereas a linear relationship results in a straight line.
On a graph, kinetic energy has a linear relationship with respect to the mass of the moving object and a non-linear relationship with respect to how fast the object is moving.
Thus, the graph of KE will be a non-linear relationship.

Explanation:
I believe the answer is D
Answer:
A
Explanation:
Carbon dioxide and water can be excreted and the energy is used by the cell
In one or two sentences, explain how the chemical equation for cellular respiration shows that plants cycle matter. Include the numbers of molecules and atoms involved to support your explanation.
Carbon dioxide + Water Glucose (sugar) + Oxygen CO2 + H2O C6H12O6 + 6O2 Cellular respiration or aerobic respiration is a series of chemical reactions which begin with the reactants of sugar in the presence of oxygen to produce carbon dioxide and water as waste products.
Glucose + Oxygen ------> ATP + Carbon dioxide + Water
C6H12O6 + 6O2 ----------> 36ATP + CO2 + H2O
The chemical equation for cellular respiration shows that plants cycle matter because oxygen and glucose that is produced by the plants is used by the human body for the generation of energy in the form of ATP molecules, water and carbondioxide gas.
This carbondioxide gas is released by animals which is used by the plants in order to make their own food during the process of photosynthesis so we can conclude that the chemical equation for cellular respiration shows that the plants cycle matter.

A population of the Galapagos finch Geospiza fortis undergoes directional selection for larger bill size after Geospiza fuliginosa colonizes the same island. This is an example of:
Answer: character displacement
Explanation:
Character displacement is an evolutionary change which happens in a scenario whereby two identical species live in same environment. When this occurs, natural selection takes place which then favors a divergence based on the characters that the organisms possess.
Therefore, when a population of the Galapagos finch Geospiza fortis undergoes directional selection for larger bill size after Geospiza fuliginosa colonizes the same island is an example of character displacement.

28. Which statement best explains why cellular respiration in plants and
other organisms is dependent on photosynthesis?
Photosynthesis is one of the final steps in cellular respiration,
Photosynthesis absorbs materials that are catalyzed during cellular respiration.
Photosynthesis absorbs excess energy produced by cellular respiration.
Photosynthesis provides the materials that fuel cellular respiration.
Answer: Photosynthesis provides the materials that fuel cellular respiration.
Explanation:
Photosynthesis, the process through which green plants convert light to chemical energy. The energy that is gotten from sunlight by green plants, some protistans, and bacteria is used to produce sugar which is then converted to ATP by cellular respiration which is regarded to as the fuel that living things use.
Therefore, the statement that best explains why cellular respiration in plants and other organisms is dependent on photosynthesis is that photosynthesis provides the materials that fuel cellular respiration.
Answer:
Photosynthesis provides the materials that fuel cellular respiration.

In what way do two alleles for the some trait differ?
A. The are found on different chromosomes.
B. They consist of different sequences of DNA
C. They are produced by two different people.
D. They are complementary.
Answer:
B. They consist of different sequences of DNA
Explanation:
Alleles are contrasting or alternative forms of a gene. A diploid organism i.e an organism with two sets of homologous chromosome, contains two alleles for each gene that encodes a trait. Although the two alleles of that particular gene encodes the same trait, they can encode different phenotypes i.e way it is expressed because they contain different sequences of DNA.
For example, in a gene coding for height in pea plants, two alleles, T and t are responsible. Allele T codes for tall height (phenotype) while allele t codes for short height (phenotype). Although the two alleles are for the same trait, they differ in the content of their DNA sequence, hence, are expressed differently or variably.
