Answer:
Genes determine which phenotypes you get
Explanation:
When you have a gene, it determines what proteins get bonded together. Such as eye color, hair color, hair type, etc.
Genes are the elements that influence traits. Alleles are the many varieties of a gene. Trait inheritance is controlled by individual alleles. While some alleles are recessive, others are dominant.
What are genes ?The term "gene" can be interpreted in a number of ways. The molecular gene is a sequence of nucleotides in DNA that is transcribed to form a functional RNA, whereas the Mendelian gene is the fundamental unit of inheritance. Protein-coding genes and noncoding genes are the two categories of molecular genes.
Chromosomes, which are found in the cell nucleus, are where genes are found. There are hundreds to thousands of genes on each chromosome. There are 46 chromosomes in all, or 23 pairs, in each typical human cell.
Some features are controlled by genes that are passed down from parents to their children, while others are learned via observation and experience, and the majority are influenced by genetics.
Thus, Alleles are the many varieties of a gene.

Black hair (B) is dominant to brown hair (b). Cross a black rabbit and a brown hair. The black rabbit had a brown haired mother.
What is the punnet square for this and the genotype and phenotype for this.
Answer:
Genotypic ratio = 1 Bb: 1 bb
Phenotypic ratio = 1 black rabbit : 1 brown rabbit
Explanation:
This question involves a gene coding for hair color in rabbits. The allele for Black hair (B) is dominant to the allele for brown hair (b).
According to this question, a black rabbit whose mother is brown haired (bb) is crossed with a brown hair rabbit. This means that the black rabbit will have a genotype 'Bb' while the brown rabbit will have a genotype 'bb'. Each parent will produce the following gametes:
Bb - B and b
bb - b and b
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Bb, Bb, bb and bb
This means that the;
Genotypic ratio = 1 Bb: 1 bb
Phenotypic ratio = 1 black rabbit : 1 brown rabbit
A rock sitting on the surface of the Earth is pushed down deep into the Earth over time and is exposed to tremendous heat and pressure over time. Although the rock does not melt, it does change into a new type of rock.
Answer:
The rock changes into a Metamorphic rock
Explanation:
Usually, metamorphic rocks start out as some other type of rock, either igneous, sedimentary or even a metamorphic rock. The process of transformation is known as Metamorphism.
When a rock sitting on the surface of the earth is pushed down deep into the earth over time and is exposed to tremendous heat and pressure over time and does not melt, it changes into a metamorphic rock.
A metamorphic rock is formed from a combination of factors such as tremendous heat, high pressure, hot fluids rich in minerals which are all found deep down in the earth.

How many grams of Oz would be needed to produce 1.875 moles of aluminum?
4 AI + 3 O2 -> 2Al2O3
Answer:
1.4063 moles of oxygen are required
Explanation:
Based on the chemical equation:
4Al + 3O₂ → 2Al₂O₃
4 moles of aluminium react with 3 moles of oxygen.
To solve this question we need to convert the moles of aluminium to moles of oxygen using the chemical reaction:
1.875 moles Al * (3 moles O₂ / 4 moles Al) =
1.4063 moles of oxygen are requiredSaturated molecules of this nutrient, which may predispose humans to cardiovascular disease, are solid at room temperature.

Answer:

Explain the difference, with sketches, between the titration curves of monoprotic acid and a triprotic acid.
Answer:
A monoprotic acid has only one equivalence point in a titration curve while a triprotic acid has three equivalence points.
Explanation:
Monoprotic acids, HA, are acids that are able to donate one proton per molecule during the process of ionization or dissociation as shown below:
HA ----> H⁺ + A⁻
A triprotic acid is a polyproprotic acid, that is acids that can donate more than one proton per molecule during ionization. a triprotic acid can donate three protons per molecule during the process of ionization. The dissociation of a triprotic acid is shown below;
H₃A -----> H₂A⁻ + H⁺
H₂A⁻ ----> HA²⁻ + H⁺
HA²⁻ -----> A³⁻ + H⁺
The value Ka, is known as the acid dissociation constant. It is found by looking at the equilibrium constant for the dissociation of the acid. The higher the Ka, the more the acid dissociates
A titration curve is the plot of the pH of the analyte solution versus the volume of the titrant added as the titration progresses.
In a titration curve in which base is added to acid, the pH rises slowly until the equivalent point at which point the pH remains constant before it begins to rise again on the addition of more base.
In a titration curve of a monoprotic acid, there is only one region in which the equivalence point is obtained corresponding to the point of acid of dissociation of all its protons.
In the titration curve of a triproprotic acid, three equivalent points are obtained corresponding to the point of dissociation of each of three protons of the triprotic acid.
The titration curves are shown below

What kind of change has occurred? OA It's a chemical reaction because a new substance has formed. O B. It's a physical change because the water and the salt kept their original properties. O C. It's an example of synthesis because two substances reacted to give one substance. O D. It's a chemical reaction because the water now tastes salty but originally did not.
HELLLPPPP PLEASEEEEE!!!!!
Answer:
B. It's a physical change because the water and the salt kept their original properties.
Explanation:
Even though it tastes like salty water, the salt is still present, just in smaller molecules. It can be brought back so it is a physical change.

How much pressure does an elephant with a mass of 2200 Kg and a total footprint area of 4500 cm2 exert on the ground?
Answer:
47911.1 pa
Explanation:
The SI base unit of pressure is pascal, which is N/m^2.
2200 kg is 2200*9.8=21560 N, and 4500 cm^2=4500/10000=0.45 m^2.
So the total pressure exerted on the ground (!!) is 21560/0.45= 47911.1 Pa.

What is one disadvantage of using nuclear fission to produce electricity?
Answer:
D
Explanation:
Answer is the last one.......
Nuclear reaction of which nuclear fission is a type has a disadvantage that it is difficult to store and dispose of radioactive wastes.
What are nuclear reactions?
There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.
In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.
In nuclear fusion,on the other hand, is a reaction which occurs when two or more atoms combine to form a heavy nucleus.Large amount of energy is released in the process which is greater than that of the energy which is released in nuclear fission process.

3. When the water level is higher outside the flask than inside, is the gas pressure inside the flask higher, lower or the same as atmospheric pressure? (Take your time to think about this. Perhaps think of what it feels like to be 10 feet under water.)
Answer:
The gas pressure inside the flask is higher than outside the flask ornthe atmospheric pressure.
Explanation:
Given a U-tube manometer with water in between each arm of U-tube. One end is open to the atmosphere while one end is sealed to a flask filled with a gas. The water in the open end of the tube is experiencing a pressure equal to the atmospheric pressure whereas the water at the end sealed of to the flask is experiencing pressure due to the gas in the flask.
If the water level in both arms of the tube are equal, then the pressure due to the gas is equal to atmospheric pressure.
If the water level in the arm sealed to the gas is higher than that of the open end, The gas pressure is less than the atmospheric pressure.
If the water level in the arm sealed to the flask is lower than the open end, the pressure due to the gas is higher than atmospheric pressure.
From the question, when the water level is higher outside the flask than inside, then the gas pressure inside the flask is higher than the atmospheric pressure.
