2)Which of the following, if damaged, would most directly hinder RNA polymerase from attaching to the beginning of a gene?
A)introns
B)exons
C)UTR's (untranslated regions)
D)snRNA
E)promoter region
Answers
A purebred tomato plant with red fruit and yellow flowers was crossed with a purebred tomato plant with golden fruit and white flowers, and the map distance is 15, which is in option C. If the promoter region is damaged, RNA polymerase can't bind, which is in option E.
What is the map distance?The map distance indicates the distance between two genes that are present on the chromosomes, and when the map distance becomes more than 50%, it indicates the two genes are present on different chromosomes. Here, the red fruit and white flowers and the golden fruit and yellow flowers are recombinants, while the other two are wild types.
Hence, the map distance is 15, which is in option C, and if the promoter region is damaged, RNA polymerase can't bind, which is in option E.

Osmosis is the movement of________molecules from an area of______concentration to an area of_________concentration until_________is acheived
Answers
Osmosis is the movement of water molecules from an area of higher concentration to an area of lower concentration until membrane is achieved.
What is osmosis?Osmosis is the naturally occurring net movement or diffusion of solvent molecules across a selectively permeable membrane from a region of high water potential to a region of low water potential in a manner that tends to balance the solute concentrations on the two sides.The spontaneous movement of water or other solvents through a semipermeable membrane is known as osmosis.Transport of solute molecules over a semipermeable membrane from a lower concentration of solution to a higher concentration.Osmosis lets an animal cell absorb water from the intestines into the blood. Here are some further instances of osmosis. Osmosis is responsible for the soil's ability to absorb water. In contrast to the soil, the concentration is higher in the plant roots.Water enters the roots as a result.Osmosis is the movement of a solvent toward a more concentrated solute across a semipermeable membrane. Osmosis can occur in a variety of liquids, including supercritical liquids, gases, and other liquids, despite the fact that water is frequently the solvent in biological systems.Learn more about osmosis here:

Answers
Plasma membranes must permit some compounds to enter and exit a cell while blocking the entry of hazardous molecules and the exit of necessary ones.
What is Plasma membrane?In other words, plasma membranes selectively permit some compounds to pass through while blocking others. The cell would be destroyed if it were to lose its selectivity, which would prevent it from continuing to function.
Certain compounds are needed by some cells in greater concentrations than by other cells; these cells must have a method of acquiring these substances from the extracellular fluids.
The movement of specific materials back and forth may cause this to occur passively, or the cell may have unique processes to assure transit. Adenosine triphosphate (ATP) is the primary kind of energy.
Therefore, Plasma membranes must permit some compounds to enter and exit a cell while blocking the entry of hazardous molecules and the exit of necessary ones.

A single codon is used to signal the beginning of protein synthesis. It is commonly called the START CODON. Locate the start codon on the chart. What are the three bases of this codon? ________
Answers
About the question:
You will find the chart in the attached files
Answer:
The strat codon is AUG
Explanation:
Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. The total number of possible codons is 64, from which 61 codify amino acids -more than one codon codify for the same amino acid-. One of these amino acids is also the start point of protein synthesis. And the left three codons are stopping translation points.
The codons indicating the initiation or stop points during the translation process are:
The start codon AUG is the most common sequence used by eukaryotic cells and places near the 5´extreme of the molecule. However, other codons might be used as well. Prokaryote cells might use the codons GUG or UUG. The end codons are UAA, UAG, UGA.

According to the age structure diagram shown Chad is most likely which type of country?
Answers
The answer is that Chad is most likely a developing country. According to the age structure diagram given in the question, the population of Chad is mostly young and has a smaller proportion of elderly people.
This suggests that Chad is most likely a developing country. Developing countries have younger populations with higher fertility rates and lower life expectancies, resulting in a larger proportion of children and young adults in the population.
As a result, the population structure of a developing country is usually characterized by a broad base (large proportion of children and young adults) and a narrow top (small proportion of elderly people).Chad is most likely a developing country due to the shape of its population pyramid or age structure diagram.

The interior of the phospholipid bilayer is _______ meaning it repels polar molecules, such as water
Answers
The cell membrane's inside is hydrophobic, meaning that water won't cling to it. In order to effectively separate fluid inside the cell from fluid outside the cell, phospholipids form a two-layer cell membrane.
Why do polar molecules repelled by the phospholipid bilayer?Large hydrophilic polar or ionic molecules find it difficult to pass through the phospholipid bilayer. The cell membrane prevents the passage of any size charged atoms or molecules.
What component of the phospholipid bilayer is water-repellent?While the tails (the lipid component) are non-polar, the heads (the phospho part) are polar. The tails, which face the inside of the cell membrane, are "hydrophobic" (fearful of water), whereas the heads, which make up the exterior and inner linings, are "hydrophilic" (lovers of water).

Which statement is not consistent with Darwin’s theory of natural selection?
Answers
Answer:
The Earth is approximately 100,000 years old. Charles Darwin thought that the Earth was only around 6,000 years old, and that all evolution had taken place during that timespan. Knowledge that the Earth is approximately 100,000 years old would not be consistent with Darwin's theory. However, fossils indicating extinct organisms, organismal survival being environment dependent, individuals not evolving, and all living species being related to common ancestors are all consistent with Darwin's theory of natural selection.
