Answer:
Enhancer region
Explanation:
An enhancer is a cis-regulatory DNA region that binds to transcription factors in order to stimulate transcription. Enhancer regions are localized both upstream and downstream of the gene whose transcription regulates, at a variable distance ranging from 1 to 100 kilobases (kb) from the transcription start site. The first enhancer to be identified was found in an intron of the immunoglobulin gene. Conversely, a silencer element is a DNA region that binds to proteins known as repressors in order to suppress transcription.

Why can’t a purine hydrogen bond with another purine within the sugar phosphate backbone of DNA? State your reason with all the details that are required to answer the question for full credit.
Answer:
due to the structural-binding properties of the nitrogen bases
Explanation:
Adenine and guanine are purines (two-carbon nitrogen ring bases) that pair with thymine and cytosine pyrimidine nitrogen bases (one-carbon nitrogen ring bases), respectively. These specific base-pair rules are due to their hydrogen bonds (i.e., van der Waals forces), which stabilize the structure of the DNA helix. Cytosine and guanine have three sites to form hydrogen bonds to each other, while adenine and thymine have only two sites. The specific interactions between purines and pyrimidines are critical for proper bonding and attachment to the sugar-phosphate DNA backbone (i.e., for the formation of the DNA double-helical arrangement).
The process of a cell increasing its size, doubling its contents, dividing into 2 independent cell, and repeating the process over and over again. a meiosis b interphase c mitosis d cell cycle
Answer:
C. mitosis
Explanation:
Mitosis is one of the two types of cell divisions in which a single cell divides into two genetically identical daughter cells. Mitosis is used for growth and repair of tissues in living organisms.
Mitosis is also the process by which cells multiply/duplicate themselves. Hence, the process of a cell increasing its size, doubling its genetic contents, dividing into two independent cell, and repeating the process over and over again is called MITOSIS.

PLEASE HELP ME WITH THIS AND HURRY WILL MARK AS BRANLIEST!!!!!! Why do leaves change color in the fall? Research this phenomenon and write a two-page report describing what happens. Be sure to include an introduction and a conclusion to your report. Use the information you have learned in this lesson about chlorophyll, the green plant pigment, and its role in photosynthesis to help you explain what happens in the fall.
Answer:
Leaves are always the color they turn in the fall
Explanation:
The chlorophyll created when the leaves use sunlight to create energy for the tree has a green pigment that covers the leaves actual colors. As the leaves separate from the trees they stop making chlorophyll, thus allowing the leaves true colors to return.
I hope this helps and good luck on that two-pager!
Answer:
During the fall the day gets shorter hence less sunlight this results to leaves stopping their food making process. The chlorophyll breaks down, the green color disappears and the yellow to orange color becomes visible

Which of the following best explains how DCMU affected the reaction?
The passive movement of particles from a region of higher concentration to a
region of lower concentration is known as...
A. Diffusion
B. Active Transport
C. Osmosis
D. Selective Permeability
Answer:
Answer is A. Diffusion
Explanation:
Because diffusion is a passive process in which a substance moves from a higher concentration to a lower concentration until the concentration becomes equal
The passive movement of particles from a region of higher concentration to a region of lower concentration is known as diffusion. Thus, the correct option is A.
What is Diffusion?Diffusion may be defined as the passive movement of particles from a region of higher concentration to a region of lower concentration.
Active transport requires energy for the movement of particles. Selective permeability may be defined as the ability to differentiate the movements of different types of particles in and out of the membrane.
Therefore, the correct option for this question is A.

Answer:
The answer is H
Explanation:
The correct answer is that the cell model E. show cell shape and tiny organelles found in the cell that helps in the identification of the cell and their organelles.
Cell models are models that represent biological cells as discrete entities. These models help in representing the cell shape and components of the cells.
These are used in various biological fields such as computational biology, cellular biology and are also used in studying the cell and comparing them to identify the cell and its organelles.
By the shape and its tiny organelles, one can identify and find the cell, as prokaryotic cells lack various cell organelles, similarly, animal cells and plant cells have distinct shapes, and some cell organelles.
Thus, the correct answer is option E. show cell shape and tiny organelles found in the cell

2. Asexual reproduction requires two parents and produces identical offspring, while sexual reproduction requires only one parent and produces non-identical offspring.
3. Asexual reproduction requires only one parent and produces identical offspring, while sexual reproduction requires two parents and produces non-identical offspring.
4. Asexual reproduction requires only one parent and produces non-identical offspring, while sexual reproduction requires two parents and produces identical offspring.
Answer:
3. Asexual reproduction requires only one parent and produces identical offspring, while sexual reproduction requires two parents and produces non-identical offspring.
Explanation:
Asexual - one parent only. Offsprings looks identical
You could see that in plants and flowers where each offspring looks the same
Sexual - two parents. Offsprings do not look identical
Ex : Animals and humans. We need a male and a female/ egg + sperm. The offsprings produced are non identical as genes from both parents are included
Answer:
3
Explanation:
asexual requires only one parent (think Jurrasic park lost worlds with the girl and the velociraptor they both are products of asexual reproduction)
sexual requires two parents to make the baby

What information would best further the understanding of the relationship between the number of amino acid codons and their frequency in proteins?
Answer:
Explanation:
The information about the structure of a protein is key to understand its function and why certain codons are distributed the way they are. We know that proteins have several structures:
The primary structure, which is defined by the sequence of nucleotides in RNA.
The secondary structure, the regular arrangement of amino acids within located regions of the polypeptide. The most common structures are α-helices and β-sheets.
The tertiary structure, the folding of the polypeptide chain as a result of the interactions between the lateral chains of the amino acids that are located in different regions of the primary sequence.
The quaternary structure, which consists of the interactions between different polypeptide chains in proteins formed by more than one polypeptide, as is the case with hemoglobin.
We know that structure and function are strongly related to one another, and a crucial determinant for the tertiary structure is the location of the hydrophobic amino acids inside the protein and the hydrophilic amino acids on the surface, where they interact with water. The interior of the folded proteins are constituted mostly of hydrophobic amino acids organized in α-helices and β-sheets, these secondary structures are located within the hydrophobic center of the protein. The bow regions that connect the elements of the secondary structure are located on the surface of the folded proteins, where the polar components form hydrogen bonds with water or with the lateral chains of the hydrophilic amino acids.

Which organelle in an animal cell would have the most water?
Answer:
The cytoplasm is the answer.
Explanation:
which of the following can be changed during meiosis? Is it a base sequence, a number of amino acids, a number of chromosomes, or a gene sequence
Answer:
Number of chromosomes
Explanation:
Meiosis is a specialized type of cell division in which the gametes are produced.
A diploid parent cell first replicates its DNA. Then, two rounds of cell division occurs to produce 4 haploid cells, each with half the amount of chromosomes. These gametes fuse during fertilization to restore the diploid state.
Therefore, meiosis changes the number of chromosomes.
