Can you define both of the following terms? (Could you condense them into 2 sentences length for each?)Conjugate baseHydrogen Ion

Answer:

A. Similarities between mitosis and meiosis include: 

both are processes of cell division or the creation of daughter cells from a parent cell

both go through the phases: prophase, metaphase, anaphase, and telophase and cytokinesis

both use most of the same machinery of cell division including centrosomes, spindle fibers, etc.

B. Differences between mitosis and meiosis include:

Meiosis is used in sexual reproduction to make four haploid (n) daughter cells from one parent cell. 

Mitosis is used for growth, replacing old cells, and asexual reproduction. One parent cell makes more 

Meiosis happens in two stages, or two rounds of division, known as meiosis I and meiosis II. Mitosis only involves one round of division, or division of the cytoplasm.

During meiosis, crossing over occurs, which increases the genetic variation of gametes. This does not happen in mitosis. 

The most logical name for a sixth mass extinction would be the quaternary extinction.

This term is used to describe the ongoing extinction event of species during the present Quaternary period, due to human activity. It is sometimes referred to as the Anthropocene or Holocene extinction. The Quaternary extinction is characterized by the disappearance of large mammals, known as the megafauna, as well as the decline of many other species due to habitat destruction, pollution, and climate change. While it is not yet clear if the current rates of extinction will result in a mass extinction event on the same scale as previous ones, it is clear that human activity is having a significant impact on biodiversity.

The feeding behavior of fish in streams that receive acidic runoff from strip mines is compared to the feeding behavior of fish in unaffected streams is a natural experiment.

Natural experiments are the experiments in which the changes in parameters are guided by natural activities without any human intervention and the conditions are such that they lie in the scope of laboratory experimentation. There will be subsequent changes in the feeding behavior of the fishes when it is in natural freshwater or in water with acidic runoff. This is because of the evolutionary changes or adaptations which the species undergo in order to maintain their population. However the parameters such as rate of oxygen transfer, BOD, population change etc. are determined by human experimenting on the data and observing the pattern for a specific duration of time. Thus, such experiments are called as natural experiments as no anthropogenic element is used to manipulate the observations.

The process of Glycolysis is a catabolic process  in which two molecules glucose goes through a ten- step pathway and yield two molecules of pyruvate . It is a major part of carbohydrate metabolism .

Mechanism Of Glycolysis

The glycolysis is also known as EMP pathway and it is involved in both aerobic and anaerobic conditions .There are two phases in the mechanism of glycolysis in which 5 reactions takes place in each phase and the process of glycolysis takes place in cytosol

Preparatory phase refers to the  generation of two molecules of  glyceraldehyde 3-phosphate from one molecule of glucose which further goes into the payoff phase . In this phase two molecules of ATP are used and two regulatory enzymes were involved in this reaction .

Payoff phase refers to the further break down of two molecules of glyceraldehyde3-phosphate to two molecules of pyruvate . In this phase four molecules of ATP and two molecules of NADH are generated . In this phase only one regulatory enzyme is involved which is the breakdown of PEP to pyruvate  .

Both the phases of glycolysis takes place in the cytoplasm and there are  three enzymes that involved in regulating the glycolytic pathway .This process is also known as the catabolic process .

In DNA replication, the 3' end of the sugar contains the hydroxyl group (3'-OH). The DNA has deoxyribose sugar, which has 2'-H and 3'-OH. By this process two DNA are formed from one.

DNA replication is the process by which the DNA makes a copy of itself with the help of different enzymes and energy (ATP). The first step is to unwind the DNA helix so that each strand can be replicated. The DNA polymerase adds the new upcoming nucleotide to the already existing 3'-OH of the nucleotide. The DNA nucleotide contains a pentose sugar that has a 2'-H and 3'-OH, a nitrogen base, and a phosphate at 5' of the sugar.

Due to the absence of 2'-OH, it is more stable than RNA. The bond that is made by the 3'-OH and 5'-P of the upcoming nucleotide is the phosphodiester bond, which is more energetic by nature.

Hence, In DNA replication, the 3' end of the sugar contains the hydroxyl group (3'-OH).

The potential loss of unique species due to a disaster is referred to as mass extinction. When large numbers of species disappear over a short time period then it is called mass extinction.

Biodiversity threats include burning fossil fuels and deforesting forests and other wildernesses for industrial agriculture. Other human activities, such as wildlife poaching and hunting, can also have serious impacts.

When ecosystem services no longer adequately meet social needs, biodiversity loss can have far-reaching, direct human health consequences. In addition, ecosystem services impact indirectly on livelihoods, incomes, local migration, and, in some cases, political conflict.

The solution is therefore choice (2). signaling that depends on contact.

A membrane protein called the Delta protein prevents neighboring cells from differentiating into neural cells. This is accomplished by attaching the Delta receptor to the membrane receptor of the next cell, creating a notch. It is hence a notch pathway.

As the Delta must attach to the membrane protein of the neighboring cell in order to communicate, this pathway is contact-reliant. Juxtacrine signaling, also known as contact-dependent signaling, is a type of cell-to-cell communication.

While paracrine signaling occurs next to cells without coming into contact with them, endocrine signaling occurs over great distances. Neurons play a role in neuronal signaling.

Answer:

it can't be used to make a protein in that cell.

Explanation:

If a gene is not transcribed in a cell, it can't be used to make a protein in that cell. If a gene does get transcribed, it is likely going to be used to make a protein (expressed). In general, the more a gene is transcribed, the more protein that will be made.

The transcription is affected as when the gene has not been transcribed the protein will not make. When a gene is transcribed, protein synthesis can happen.

Gene expression begins with transcription. To create an RNA molecule, the DNA sequence of a gene must be copied. RNA polymerases, which join nucleotides to create an RNA strand, carry out transcription (using a DNA strand as a template).

A gene cannot be used to produce a protein in a cell if it is not transcribed there. If a gene gets transcribed, it will probably be used to produce a protein (expressed). In general, more protein will be produced the more a gene is transcribed.

Therefore, the transcription is impacted since the protein cannot be produced if the gene is not transcribed. Protein synthesis can take place when a gene is transcribed.

This  is a form of natural selection that occurs when members of one sex  choose mates based on certain traits, leading to the evolution of exaggerated or ornamental traits in the other sex .

The behavior of male Birds of Paradise demonstrates natural selection in action. The males with the brightest colors and longest feathers are more attractive to females and therefore more likely to mate and pass on their genes to their offspring.

This creates a selective pressure that favors the evolution of these traits, as they become more and more exaggerated over time. In other words, the flashy males are more successful in reproducing, and their offspring inherit their showy characteristics, leading to the perpetuation of these traits in the population.

An example of osmosis occurs when a sugar solution and water, top, are separated by a semipermeable membrane. The solution's large sugar molecules cannot pass through the membrane into the water. Another good example of osmosis would be dipping a sponge into water, because there is a higher concentration outside, so the water goes in and makes the sponge expand

Answer:

B) the shriveling of a cell after salt is poured on it

Explanation:

During osmosis, water moves from a low concentration to a high concentration. Since the salt is outside the cell membrane, it makes the outside have a higher concentration than the inside of the cell; causing the water to move from the cell and the cell shriveling.
