when you are frightened, your nervous system initiates the fight or flight response. as part of this response, adrenaline is released in your bloodstream and binds to a g protein adrenaline receptor on your muscle cells. the g protein signal transduction pathway eventually results in activating glycogen phosphorylase, the enzyme that breaks down glycogen (a starch stored in muscles) into glucose. the glucose is now available to be used by the muscles for fighting or fleeing.

Answer:

37oC - temperature

It is important that the temperature is controlled because it maintains consistency and safety.

Explanation:

-Temperature is a common type of controlled variable.

-A control variable is anything that is held constant or limited in a research study

Repeatability is the likelihood that a single person can obtain consistent results while repeating the experiment multiple times. Reproducibility is the probability that multiple researchers can reproduce the same results using the same methods and materials.

The major difference between the two is the fact that repeatability is the capacity of a person to replicate the same results on the same data set using the same procedures. Reproducibility, on the other hand, is the ability of multiple researchers to get similar outcomes using different data sets, equipment, or methods.

Repeatability example: When a scientist conducts an experiment several times and obtains comparable results each time, this is referred to as repeatability. For instance, if a chemist weighs a sample ten times and gets the same weight each time, they have achieved repeatability.

Reproducibility example: If a scientist conducts an experiment, writes a report, and submits it to a scientific journal, and another researcher follows the methods outlined in the original report and obtains the same results, the experiment is said to be reproducible. In other words, it is the ability of an experiment to produce the same results when repeated by a different person or team.

If you were looking at a frog's lifecycle, you would find more specialized cells in the adult frog stage (option b).

In a frog's lifecycle, the adult frog stage is where you would find more specialized cells. This stage occurs after the frog has gone through various developmental stages, starting from the beginning ball of cells.

1. The beginning ball of cells: This is the initial stage of a frog's development. It starts with the fertilization of the egg and the formation of a zygote. At this stage, the cells are not yet specialized and are in the process of dividing and multiplying.

2. Developing tadpole: After the beginning ball of cells, the zygote undergoes further development and transforms into a tadpole. The tadpole stage is characterized by the presence of gills and a tail. The cells in this stage are becoming more specialized but are still relatively unspecialized compared to the adult frog stage.

3. Adult frog: The adult frog stage is the final stage of the lifecycle. At this point, the tadpole has undergone metamorphosis and has transformed into a fully developed frog. In this stage, the cells have become highly specialized to perform specific functions necessary for the frog's survival, such as muscle cells, nerve cells, and specialized organs like the heart and lungs.

4. The same amount at all stages: It is not accurate to say that there is the same amount of specialized cells at all stages of the frog's lifecycle. As the frog develops and goes through metamorphosis, the cells differentiate and specialize to fulfill specific roles and functions required for each stage of development. The highest concentration of specialized cells is found in the adult frog stage.

Carlota’s body is made up of many cells. One thing that all her body cells have in common is that they contain genetic material in the form of DNA.

DNA (deoxyribonucleic acid) is the fundamental genetic material that carries genetic instructions for the development, function, and reproduction of all living organisms. It is found in the nucleus of cells and consists of four nitrogenous bases (adenine, guanine, cytosine, and thymine), a sugar molecule, and a phosphate molecule.

However, some slight variations can occur as a result of mutations or genetic modifications over time. The arrangement of these bases in a specific order determines the genetic code, which directs the production of proteins and other molecules needed for cellular activities and physiological processes in the body. Therefore, one of the essential things that all of Carlota’s body cells have in common is the presence of DNA as the genetic material. The DNA within each cell of her body is almost identical.

The profit is 15 pesos and the percent profit is 3%.We find the profit, by subtracting the cost price (the price at which the product was bought) from the selling price.

In this case, the product was bought for 500 pesos and sold for 515 pesos, so the profit is 515 pesos - 500 pesos = 15 pesos.To calculate the percent profit, we use the formula:

Percent Profit = (Profit / Cost Price) * 100

Substituting the values, we have:

Percent Profit = (15 pesos / 500 pesos) * 100

Percent Profit ≈ 3%

Therefore, the profit made on the product is 15 pesos and the percent profit is approximately 3%.

The easiest way to characterize budding is as asexual reproduction that produces genetically identical offspring.

A type of asexual reproduction in which offspring develop from the parent organism's reproductive system. Although some species have buds practically everywhere on their bodies, buds frequently only appear in certain places. In yeast, budding typically happens when there is a plentiful supply of nutrients. As the mother grows, this reproductive process results in tiny shoots. The parent yeast nucleus then divides into two, one of which moves into the bud. Yeast often reproduces asexually through a process known as budding. On the parent cell, a little button or bud develops, matures, and finally divides into a new yeast cell. Genetically speaking, the parent cell and this new yeast cell are identical.

Answer: positive sodium ions

Explanation:

This relates to the Action Potential which is what a nerve cell goes through when it needs to send information down the nerve cell to another cell and so on till it gets to the destination of the message.

The information is transmitted when the segments of the axon fire and when they do, positive sodium ions come in from outside the cell to the inside thereby making the inside positive. The previous segment would return to a resting potential when potassium ions which are negative, rush into the cell.

Answer:

Explanation:

Just like the ABO alleles, each biological parent donates one of their two alleles to their child. A mother who is Rh- can only pass an Rh- allele to her son or daughter. A father who is Rh+ could pass either an Rh+ or Rh- allele to his son or daughter. This couple could have Rh+ children (Rh- from mother and Rh+ from father) or Rh- children (Rh- from mother and Rh- from father).

Answer:

Thats alotta points

Explanation:

If the new purple gene is recessive and both parents have yellow skin (heterozygous), then they would carry one copy of the purple allele (Y) and one copy of the yellow allele (y).

To determine the probability of getting the mutated purple allele (y) for the new aliens, we can use a Punnett square to visualize the possible combinations of alleles.

Let's represent the father's alleles as Yy and the mother's alleles as Yy as well. The Punnett square would look like this:

| Y | y |

-----------------------

Y | YY | Yy |

-----------------------

y | Yy | yy |

In the Punnett square, the top row represents the possible alleles from the father (Y and y), and the left column represents the possible alleles from the mother (Y and y).

The four possible combinations in the Punnett square are:

- YY (yellow skin)

- Yy (yellow skin)

- Yy (yellow skin)

- yy (purple skin)

So, out of the four possible combinations, there is one combination that results in the new purple skin allele (yy). Therefore, the probability of getting the mutated purple allele for the new aliens is 1 out of 4, which can be simplified to 1/4 or 0.25 (25%).
