Drag each item to indicate whether it exhibits fracture or cleavage.
Answer:
From left to right
Explanation:
Cleavage, cleavage, fracture
The first item exhibit a cleavage. The second item exhibit a cleavage. The third item exhibit a fracture.
In mineral science, Cleavage is the process by which a mineral breaks or splits through smooth planes with a pattern because the material is stratified in a layered pattern. It generally seems regular since it fractures along its plane of weakness.
A fracture happens when a mineral splits with fractures and does not produce a particular definite shape. It frequently emerges in an erratic and irregular pattern.
From the three picture given, the first and the second item exhibit cleavage, and the third item exhibit fracture.

Explanation:
1. In human beings, a downward-pointed frontal hairline ("widow's peak") is a heritable trait. A
person with a widow's peak always has at least one parent who also has this trait, whereas
people with a straight frontal hairline may occur in families in which one or even both parents
have widow's peaks. When both parents have a straight frontal hairline, all children also have
a straight hairline. Using A and a to symbolize alleles for this trait, what is the genotype of an
individual without a widow's peak? (Show your work)
The genotype of an individual without a widow's peak would be aa.
A person with widow's peak has. at least a parent with the trait. When both parents have a straight frontal hairline, all the children also have a straight frontal hairline.The above features are indications that widow's peak is a dominant trait.
Since A and a are used to represent the alleles, AA or Aa will be the genotype of individuals with widow's peak while only aa will be the genotype of individuals with straight frontal hairlines.
In other words, individuals without a widow's peak will have aa as genotypes.

Explain why water is essential for the light reactions.
Answer:
During the process of photosynthesis, six molecules of carbon dioxide and six molecules of water react in the presence of sunlight to form one glucose molecule and six molecules of oxygen. The role of water is to release oxygen (O) from the water molecule into the atmosphere in the form of oxygen gas (O2).
Explanation:
Water is important for photosynthesis because it the source of hydrogen for the sugars created through photosynthesis

O A) It is used to sort DNA strands.
B) It is used to produce more DNA strands.
C) It is used to measure DNA strands.
D) It is used to break down DNA molecules.
Answer:
used to separate mixtures of DNA, RNA, or proteins according to molecular size
Gel electrophoresis is used for the separation of genetic material present in the cell such as DNA, RNA and even proteins. Thus, the correct option is A.
What is Gel electrophoresis?Gel electrophoresis is a technique which is used to separate the genetic material such as DNA fragments, RNA and proteins on the basis of their size and charge. Gel Electrophoresis involves running an electric current through a gel containing the molecules of interest in it.
The principle of Gel electrophoresis is that the DNA or protein sample to be separated is loaded on to a porous gel placed in an ionic buffer. On the application of electric charge, each of the molecules having different size and charge will move through the gel at different speeds and therefore separates out.
Therefore, the correct option is A.

what type of weather is typically associated with the air pressure system near Salem
Answer:
According to common weather maps of the region surrounding Salem, Massachusets, the weather typically associated with the air pressure system is rain.
Explanation:
Given the nature of warm air and its tendency to rise, warmer regions tend to fall under the low-pressure system category. These systems, due to the movement of the warm air, have lower pressure at their center than in the areas surrounding them. As the wind blows towards the low-pressure air systems, the cooler and warmer air meet within the atmosphere, which causes the water vapor to condense and form clouds. Oftentimes, these clouds then precipitate, causing rain.

Answer: A geneticist studies a series of families in which both parents are normal and at least one child has albinism. The geneticist reasons that both parents in these families must be heterozygotes and that albinism should appear in of the children of these families. To his surprise, the geneticist finds that the frequency of albinism among me children of these families is considerably greater "Than . Can you think of an explanation for the Thigher-than-expected frequency of albinism among These families?

In gymnastics, a gymnast must be able to balance on a balance beam. What is the best explanation for what forces are acting on the gymnast on a balance beam? (2 points)
The forces are balanced when the force of gravity pulling you down is the same as the force of the balance beam pushing you up.
The forces are unbalanced when the force of gravity pulling you down is the same as the force of your legs pushing you up.
The forces are balanced when the force of gravity pulling you down is stronger than the force of the balance beam pushing you up.
The forces are unbalanced when the force of gravity is reduced to the same force as the balance beam pushing you up.
Answer:1
Explanation:Because gravity always pulls you down even when your standing on an object.
Describe a hypothetical result of the fluctuation test that would have supported the hypothesis that mutations occur in response to an environmental challenge, and explain how this result was different from the observed result described above
In order to support the hypothesis that mutations occur in response to an environmental challenge, the experiment in question would have to show an increase in mutation rates shortly after the environmental challenge was introduced.
When we test a hypothesis, we perform an experiment and gather data over the course of the testing. In order to obtain evidence that supports a hypothesis, we have to ensure that only one variable is changing and be sure to repeat the experiment to confirm the values measured.
Taking this into account, a hypothetical result of the fluctuation test that would support the hypothesis of mutations in reaction to environmental challenges would be to measure a spike in mutation rates in the generation following an environmental challenge, and then continue to do so with future post-challenge generations.

Which side is hypertonic ? A or B ?
Which side will gain water
What is c ?
Answer:
1-b
2-b
3-phospholipid bilayer
B side is hypertonic. It will gain water. C is Phospholipid layer.
What is Hypotonic Solution?
A hypotonic solution is a type of solution that has a lower osmotic pressure than any other solution to which it is compared. It is a solution in which a small amount of solute passes across a semipermeable membrane compared to the amount of solute in the other solution.
If the solute concentration outside the cell is lower than inside the cell, these solutes cannot cross the membrane, so the solution is hypotonic to the cell.
The cell membrane consists of a phospholipid bilayer containing embedded proteins present between these two solutions where a hypotonic solution has a relatively low concentration of solutes.
Thus, B side is hypertonic. It will gain water. C is Phospholipid layer.
