Answer:
The DNA of prokaryotes is not enclosed within a membrane, and is instead localized to a region called the nucleoid. This DNA acts as the prokaryote’s only chromosome, so the process of DNA replication is much quicker. After DNA replication, the original chromosome and its copy seperate. A cleavage furrow forms between the cell, the cell eventually pinches in half, and two identical daughter cells, each with an identical chromosome, are formed.

Which is true of how Southern States responded to the 14th and 15th Amendments following Reconstruction?
A) Southern States reluctantly agreed to and followed the 14th and 15th Amendments.
B) Southern States passed what became know as the "Corrupt Bargain" to nullify these amendments.
C) Most southerners protested that these amendments were unconstitutional without first passing the Civil Rights Act of 1964.
D) Southern States passed "Jim Crow laws" to suppress black voters and maintain segregation.
Answer:
The answer is they passed the Jim Crow Laws, D
The 14th and 15th Amendments protected African Americans' right to citizenship and the right to vote. Southern States passed "Jim Crow laws" to suppress black voters and maintain segregation. Thus option D is correct.
What is Jim Crow laws?During the 1880s and 1960s, a majority of American states are forced to segregation through a law called jim crow law which was applied From Delaware to California, and from North Dakota to Texas, many states impose legal punishments on people for consorting with members of another race.
some of the common types of laws forbade intermarriage and ordered business owners and public institutions and separate their black and white clientele.
This law is a part of of American history with having been enacted at the state and local levels to mandate and maintain racial segregation in the southern United States.
The Jim Crow Laws are economic, social, and educational woes that blacks living in the South have been forced to live with for decades.

Hello there!
Albinism is a rare group of genetic disorders that cause the skin, hair, or eyes to have little or no color. Albinism is also associated with vision problems. According to the National Organization for Albinism and Hypopigmentation, about 1 in 18,000 to 20,000 people in the United States have a form of albinism. A group of inherited disorders characterized by little or no melanin production.
This condition increases the risk of skin cancer.
Most people with albinism have pale skin, eye conditions, and are sensitive to the sun.
No cure exists, but skin can be protected and eye conditions can be treated.

how can an understanding of the interactions between matter and energy help you understand whether different carbon reservoirs are growing or shrinking?
Answer:
Carbon reservoirs are shrinking.
Explanation:
the interactions between matter and energy help us to understand and provides information whether different carbon reservoirs are growing or shrinking because when the matter converts into energy, it releases heat energy along with different gases. For example, when volcanic eruption occurs the carbondioxide gas is released in this process which shows that carbon reservoirs are shrinking.
Answer:
By understanding the amount of energy devoted to processes that release carbon versus processes that store it, one can gain an understanding of how the carbon concentrations in different reservoirs are changing.
The 1st Law of Thermodynamics states that energy is neither created nor destroyed only transfer to forms. Why is a food chain an excellent example of this Thermodynamic law?
Answer:
Food chain is an excellent example of the first law of thermodynamics.
Explanation:
First law of thermodynamics states that energy of the universe is constant. It is always found in the universe in some form or the other. It cannot be destroyed or totally used up and we cannot also create energy out of anything in this world. Energy transforms from one form to another form.
Food chain is considered to be an excellent example of 1st law of thermodynamics. Every living organisms in the world posses energy. And all living organisms consumed each other or eat each other for their survival and consumes these energy to survive. So the energy possessed in one organisms or animal is transferred to the other organism that is higher in the food chain when they eats the lower organisms or animal in the food chain.
Thus energy transfers form one form to another.

Explain how scientists use geologic time to determine the age of landforms. (3 points)
Answer:
I will!
Explanation:
to determine the related age of different rocks geologists start with the assumption that unless something has happened in the sequence of sedimentary rock layers the newer Rock layers will be on top of the older ones this is called the rule of superposition with absolute age dating you get a real age and actual years
Answer:
Geologic time uses the layers of rock to describe the relationships of events and their sequence in chronological order over the history of Earth. The layering is a result of the buildup of tiny bits of rock, sediment, or lava cooling at the surface over many years. Think of it like a stack of pancakes—the bottom layer is the one that was placed first and therefore is the oldest. The sediments that create the layers of Earth are stacked one on top of the other.

You overhear your mom and dad talking about having a well installed in your yard. What advice can you offer them about determining the placement and potential effectiveness of the well? Think about what you know about how wells factor into the groundwater systems running below the surface of the Earth.
Answer:
Built well where water table present nearer to surface.
Explanation:
My advice for them about determining the placement and potential effectiveness of the well is that the well should be installed where the groundwater present nearer to the surface, the reason behind this advice is that minimum work and energy will be used for digging well. If the water table is present very deep, more work and energy will be utilized on the digging of the well. Those areas where more rainfall occurs, the depth of water table is less as compared to arid zones because due to more rainfall more water goes inside the soil and the water table rises.

Explanation:
Nuclear fusion is the process by which two or more atomic nuclei join together, or “fuse,” to form a single heavier nucleus. During this process, matter is not conserved because some of the mass of the fusing nuclei is converted to energy, which is released. Fusion is the process that powers active stars, releasing large quantities of energy.

Sickle cell anemia is caused by a mutation that alters red blood cells. HELP ME PLZZ!!!
Answer:
In Sickle Cell Anemia:
Mutation that occurs in DNA is due to the substitution of thymine base by adenine base. Change in mRNA consists of a change of the GAA codon to GUA, which codes for a different amino acid. The change that occurs in the synthesized protein is the substitution of glutamic acid by valine, the consequence of which is the structural alteration of this protein.Explanation:
Sickle cell anemia is a disease that is transmitted from parent to child in an autosomal recessive inheritance pattern. It is due to a mutation that is capable of altering the shape of the erythrocyte, as well as its ability to circulate and carry oxygen.
First, a puntual genetic mutation occurs, where the sequence of DNA bases that determines the synthesis of the hemoglobin β-chain, by suffering the substitution of thymine by an adenine: CTT → CAT.The transcription of this altered sequence to mRNA results in the change of the GAA codon to GUA, which encodes a different amino acid.Once the β-chain is synthesized, in its structure there is a change in the amino acid sequence, due to the substitution of glutamic acid by valine.The interaction of valine with the other amino acids of the protein promotes a structural change, responsible for the deformation of the red blood cell that characterizes sickle cell anemia.
What happens when an organism is eaten? A. All of its energy is returned to producers. B. All of its energy is gone when it dies and cannot be reclaimed by the ecosystem. C. A small portion of its energy is absorbed by the consumer, the rest is transformed into heat or waste. D. All of its energy is absorbed by the consumer.
Answer:
The higher organisms eat the lower organisms, break down their matter and rearrange the molecules to make their own matter. When any organism dies, the remains are broken down and put back into the cycle as inorganic molecules. Each of these organisms eat organic matter to produce energy and small pieces of matter.

In a certain plant, the allele for red flower color (R) is dominant over the allele for white flower color (r). A cross is performed between a plant with red flowers and a plant with white flowers. The offspring are 47 plants with red flowers and 51 plants with white flowers. What are the genotypes of the parent plants?
Answer:
Rr and rr
Explanation:
The genotypes of the parents would be heterozygous red (Rr) and true-breeding white (rr).
Since the allele for the red flower color (R) is dominant over that of the white flower color (r), for a cross to produce both red and white flower color plants, the red parent must be heterozygous (Rr) and the white parent true-breeding (rr).
Rr x rr
Rr Rr rr rr
Rr = red
rr = white
If the red parents is true-breeding
RR x rr
Rr Rr Rr Rr
All their offspring would be red without any white flower color.
Hence, the genotypes of the parent are Rr and rr.
