Answer:
Point Mutation
Explanation:
The type of change described, where the code for proline is changed to the code for leucine during division, is known as a point mutation. The correct option is C.
A point mutation refers to a change in a single nucleotide base of the genetic material (DNA or RNA).
In this case, the change occurred at a specific position in the genetic code, resulting in the substitution of one nucleotide for another. This substitution led to a different amino acid being incorporated into the protein sequence.
Thus, based on the description provided, the correct answer is C. point mutation, as it involves the specific substitution of one nucleotide for another in the genetic code.

Sams mother is cooking breakfast in a cast-iron frying pan. based on what sam is learning in his 8th grade science class,what can he state about the pan
Iron frying pan skillets heat slow and not like nonstick or stainless steel pans.
Which substance catches heat fast ?Compared to nonstick or stainless steel pans, cast-iron skillets don't heat up as evenly, but they hold their heat very well. In order to ensure that the skillet is evenly heated, preheat it on low to medium heat for 5 to 10 minutes. To check if the pan is hot enough and ready to use, carefully move your hand over it.
Cast iron and aluminum both conduct heat more slowly than copper, which does so five times more quickly. The lightest aluminum pan weighs barely two pounds, in contrast to the copper and iron pans, which each weigh over five pounds.

Explanation:
The _____ of the amino acid has the greatest influence on the overall structure of a protein.
The amino acid's R group has the most impact on the entire protein structure.
Amino acids are tiny particles that serve as the foundation for proteins. Proteins provide structural support within the cell and participate in numerous critical chemical reactions. Each protein is a compound composed of various combinations of 20 different kinds of more straightforward, smaller amino acids. Protein molecules are three-dimensional chains of amino acids.
R groups come in various forms, sizes, reactivities, and charges. As a result, amino acids can be classified according to the chemical properties of their substituent groups.

Ecological succession are the natural gradual changes in the types of species that live in an area we may refer to ecological succession as either primary or secondary the graphic represents an example of primary succession which begins in an area that has no living organisms present. notice in the illustration the first organisms to inhabit the area undergoing succession are lichens and Moss. what a biotic feature restricts the growth of more diverse plants in this area.
Answer:
The lack of topsoil inhibits the growth of more diverse organisms in the region.
Explanation:
Following catastrophic or destructive events, primary succession occurs with the growth of the microorganisms. Here a non-habitable area is exploited by a colonizing organism. For instance, lichens and moss break down rock and decompose to add nutrients to sediment creating topsoil.
Ultimately, these make the environment more livable by nutrient cycling, weathering, etc., which ushers in secondary succession. Here over time, the cultures become more dynamic, more diverse and an ever-larger food web.
In the first stage of primary succession after there has been a volcanic eruption, the soil quality will be poor. Plants that are good soil formers, such as lichens and moss, will improve the soil. Over time, with increasing plant diversity, rich soil with humus will form that will improve water retention. Taller and more diverse plants will allow for more filtered sunlight and more moderate soil temperatures.
what makes up cell membranes and is used to create hormones?(1 point) glucose glucose cholesterol cholesterol starch starch hydrocarbon hydrocarbon
Cholesterol makes up cell membranes and is used to create hormones.
Cell membranes are the outer covering of the cell that protect it from the outer environment. A cell membrane is a bilayer of lipid, composed of protein and cholesterol as well. The cholesterol is essential to maintain the proper integrity of the cell membrane.
Hormones are the chemical messengers that are released at one site and they perform their function at another location of the body. Hormones can be made up of several macromolecules like polypeptides, amine acids or cholesterol. The example of hormones made up of cholesterol are: glucocorticoids, mineralocorticoids, and sex hormones.

Anne Hutchinson was executed for teaching that worshipers needed neither the church nor its ministers to
interpret the Bible for them. Why is it false
It is false. she was banished (from Massachusetts Bay Colony). Government and church leaders believed that because doing so would upend Puritan society's patriarchal framework, women shouldn't instruct men or criticize pastors.
Anne Hutchinson, was a religious liberal who helped found Rhode Island after being expelled from the Massachusetts Bay Colony (baptized July 20, 1591, Alford, Lincolnshire, England—died August or September 1643, Pelham Bay, New York [U.S.]). In colonial New England, Anne Hutchinson was a prominent Puritan spiritual figure who questioned prevalent religious beliefs. Hutchinson earned the disapproval of the colony's elders due to the popularity of her preaching and her unconventional beliefs.
She held the belief that those who worshipped God via a personal connection, without the need for any church action, were welcome in heaven, in clear contravention of Puritan ideology and church structure. Hutchinson and her family were expelled from the Massachusetts Bay Colony as a result of these and other views. The Puritan officials who oversaw the colony compelled Anne Hutchinson to strictly abide by their regulations of worship, but she continued to hold religious gatherings in her home as she had in England. In 1637, she was tried, found guilty, and exiled from Massachusetts.

1 .Electrophoresis is a laboratory technique used to separate DNA, RNA, or protein molecules based on their size and electrical charge.
2.Gel electrophoresis is a technique used to separate DNA fragments (or other macromolecules, such as RNA and proteins) based on their size and charge.
... [All DNA molecules have the same amount of charge per mass. Because of this, gel electrophoresis of DNA fragments separates them based on size only.]
3.Gel electrophoresis [ pls chck tiz answer!]
4.DNA is negatively charged, therefore, when an electric current is applied to the gel, DNA will migrate towards the positively charged electrode. Shorter strands of DNA move more quickly through the gel than longer strands resulting in the fragments being arranged in order of size.
5.A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable.
Why buffer is used in electrophoresis?High-quality buffers are an important part of electrophoresis. They allow a current to be carried through the sample while resisting pH changes in the overall solution.

Answer: The skin doesn’t synthesize vitamin B only vitamin D.
Explanation:
The skin is responsible for protection of organ systems, muscles, tissues etc. It also is used to help regulate the body’s temperature to maintain homeostasis. Sensation is another function of the skin which helps to provide you with the sense of touch. Vitamin D production is also a function of the skin when you are exposed to sunlight, the sun synthesizes vitamin D. But the skin does not synthesize vitamin B. The skin is responsible for excretion through sweat.

Which type of chemical reaction does the equation represent?
Answer:
Synthesis
Explanation:
A synthesis chemical reaction is where two simpler substances form together to create a more complex product.
The reactants can be either a single element or a compound, but the product is always a compound.
Since Mg and O2 reacted to create MgO, a compound, this represents a synthesis reaction.

They have hydrophilic heads and hydrophobic tails.
They have hydrophobic heads and hydrophilic tails.
They have hydrophobic heads and tails.
Answer:
They have hydrophilic heads and hydrophobic tails.
Explanation:
Phospholipid membranes are comprised of a chain of lipids. These typically are arranged in a bilayer; the hydrophilic lipid heads are polar, and face outwards, while the hydrophobic tails are polar facing inwards.
The membranes are selectively permeable, and only allow the movement of small, non-polar molecules through the bilayer.
