A mutation has occurred that results in a drastic reduction in mRNA transcription from very high levels to low levels. What region is likely responsible?

Answers

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.

C: CLAY,ORGANIC LAYER, GRANITE
D: GRANITE, ROCK, SOIL

Answers

soil, rock, organic layer

Explanation:

Permeability is the ability of a layer of rock to transmit fluid such as oil or water

The factors that affect the permeability of a rock layer includes the sizes of the rock particles, the ratio of the available voids to the solid mass of the rock, the presence of trapped air and the presence of organic matter

Rocks such as gravels, and  sparingly cemented sands have high permeability

The most impermeable of the options are granite and clay which for granite has large particle mass and contain no voids while clay has very fine particles packed together with little room for water

Therefore, water moves easily between layers  soil, rock, organic layer

What amazing thing can plants do with carbon dioxide and water molecules? How?

Answers

Plant Inhalation and Exhalation
Once the carbon dioxide enters the plant, the process begins with the help of sunlight and water. During this process, the plant combines carbon dioxide with water to allow the plant to extract what it needs for food. The plant uses sunlight as energy to perform this chemical reaction.

Answer:

In the process of photosynthesis the plants make their own food by using carbon dioxide, water, sunlight and soil.

The energy from sun light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen.

If a more concentrated initial solution of sodium bicarbonate was used in beaker C, would it require more or less bicarbonate to neutralize the acid? Why?

Answers

Answer:

It would require less bicarbonate to neutralize the acid.

Explanation:

Sodium bicarbonate NaHCO3 is a, partly soluble sodium salt that decomposes in water to form a weakly basic buffer solution. It dissociates in water resulting in bicarbonate anions HCO− , sodium ions Na+ and H+.

2 NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(g)

Buffer solutions exist in equilibrium. In a  solution with a strong acid and the conjugate base react, while the other carbonate ions dissociate to form carbonic acid, shifting the equilibrium of the solution back towards a balanced state.

HA  H+ + A-

Due to its buffering ability i.e. how well it maintains equilibrium, less bicarbonate would need to be added later on to neutralize the acid.

Less quantity of bicarbonate is needed for the neutralization of acidic solution.

Function of bicarbonates

It require less bicarbonate to neutralize the acid because of its concentrated solution. If a more concentrated solution of sodium bicarbonate is used to neutralize the acid, lower quantity of it will be enough to neutralize it. Sodium Bicarbonate acts as a buffer which is commonly used for maintaining the pH of the solution.

Effect of Buffer

It acts as a base when it is put in the acidic solution so helps in neutralizing the solution so we can conclude that less quantity of bicarbonate is needed for the neutralization of acidic solution.

Identify two cell structures that are missing from Clara’s model. ____

Describe the function of each cell structure you identified in the question above. ___

Answers

B. Animal cell, I believe so because of the shape of the cell and it does not clarify if it has a cell wall, if it has a cell wall and mehran then it's a plant cell if it only has a cell membrane in them it's an animal cell

Clara's model represents an animal's cell. The Golgi body and ribosome are missing. Hence, option B is correct.

What are the functions of different cell organelles?

The gel-like substance that fills a cell is called cytoplasm. It serves as a catalyst for chemical reactions. It offers a foundation for other organelles to function within the cell. A cell's cytoplasm is where all of the processes for cell division, growth, and replication take place.

The nucleus' principal jobs include storing the cell's DNA, preserving its integrity, and assisting with transcription and replication. The main function of the nucleolus is to facilitate and assemble ribosomes. The plasma membrane is the outer covering of the cell, which provides it protection and allow the transportation of nutrients and other essential material into the cell.

In Clara's model cell wall is absent. Hence, option B is correct.

the release of.one phosphate group from ATP powers the reactions in the cell. Which phosphate is the one released from ATP

Answers

Answer:

Hey sorry, Considering this was ages ago did you finish this? what was the answer? Its too late to comment but can you rate the answer (like if it's the first option [which is #2] rate it 2 stars or if its C rate this 1 star, so on and so forth)

Explanation:

Sorry

A phosphate that is released from ATP is the third one. Thus, the correct option for this question is D.

What is ATP?

ATP stands for Adenosine triphosphate. It may be defined as a type of high-energy compound that significantly delivers energy to the cells for the accomplishment of metabolic activities. Therefore, it is known as the energy currency of the cell.

The removal or elimination of the phosphate group from ATP to yield ADP significantly liberates energy. This released energy is captured or consumed by the cells of living organisms in order to derive energy for the completion of metabolic activities. While the adjoining of these phosphate groups significantly required energy.  

Therefore, the third phosphate is the one that is released from ATP. Thus, the correct option for this question is D.

10. Use the theory of evolution to explain the observation that there are no tuskless males in the
park. WHY do males retain their tusks, when 50% of females lost them.
Type Here

Answers

Tusks are essentially overgrown teeth. Yet they’re typically used for most task of daily living; digging for water or vital minerals in the ground, debating trees to secure fibrous food, and helping males compete for females

Based on the theory of evolution, poaching of males for their tusk exacted a pressure on the elephant population which made more tuskless males to survive more than males with tucks as a result of natural selection.

Also, tucklessness as a trait is sex-linked, this explains why 50% of females lost their tusks why the males retain theirs.

Recall:

The theory of evolution describes the change that occur overtime through natural selection, whereby, offspring that are "fitter" are reproduced.Those that lack the fitness to survive produce fewer offspring than will survive.

Male elephants are known to have tusks. However, poaching of elephants with tusks have exacted the pressure of natural selection on the population of elephants in the park.

The few tuskless males that are left surviving therefore produce more offspring as they pass the gene of tucklessness to their offspring. Over a long time, more tuckless males emerge while males with tusks will become almost non-existence as a result of natural selection.

A study showed that most females elephants have no incisors which suggests that the trait for tucklessness is sex-linked. This explains why 50% of the females lost their tusks and males retain theirs.

In summary, based on the theory of evolution, poaching of males for their tusk exacted a pressure on the elephant population which made more tuskless males to survive more than males with tucks as a result of natural selection.

Also, tucklessness as a trait is sex-linked, this explains why 50% of females lost their tusks why the males retain theirs.

Assuming DNA is replicated correctly (so there are no mutations),
in which of the scenarios below would the gametes produced all
be genetically identical?

Answers

Answer:

None of the choices would lead to all identical gametes.

Explanation:

Gametes are sex cells produced by sexually reproducing organims via a process of cell division called MEIOSIS. Meiosis is a cell division process which produces four (4) daughter cells (gametes), which are genetically different from the parent cell.

The difference in genetical content is as a result of a process unique to only meiosis called CROSSING-OVER OR RECOMBINATION. This process ensures that the genetic content of the gametes are altered. Hence, since gamete formation is done via meiosis, none of the scenarios in the option will lead to all identical gametes.
