Answer:

C. hormone molecules

Explanation:

hormones are secreted in glands and are transported to the organs where they affect it and cause changes.

True. DNA can only be extended by DNA polymerase in the 5' to 3' direction. This is so that the 5' phosphate group and the phosphodiester bond can be formed, which is catalysed by DNA polymerase.

Using a deoxyribonucleotide, DNA polymerase separates the two terminal phosphates from the nucleotide's 5' end and then uses the free energy to create a phosphodiester bond.

DNA polymerase can only synthesise in one direction by extending the 3' end of the previous nucleotide chain because it needs a free 3' OH group to begin synthesis. As a result, DNA polymerase travels in a 3'–5' direction along the template strand.

A large increase in cortisol would likely result in decreased insulin secretion and increased glucagon secretion. Therefore, the correct answer is "insulin would be decreased, glucagon would be increased."

Cortisol is a hormone produced by the adrenal glands in response to stress. It has a number of physiological effects on the body, including the regulation of blood sugar levels. Cortisol increases blood sugar levels by stimulating the production of glucose from the liver, which is then released into the bloodstream. It does this by decreasing the uptake of glucose by peripheral tissues and increasing the breakdown of glycogen (stored glucose) in the liver.

Glucagon, on the other hand, is a hormone produced by the pancreas that stimulates the liver to break down glycogen and release glucose into the bloodstream. It is released in response to low blood sugar levels.

- the discovery of the Pangaea Theory.

In 1912 Alfred Wegener (1880-1930) proposed that the continents were once compressed into a single protocontinent which he called Pangaea (meaning "all lands"), and over time they have drifted apart into their current distribution.

The east coast of South America and the west coast of Africa seem to fit together like pieces of a jigsaw puzzle, and Wegener discovered their rock layers “fit” just as clearly. South America and Africa were not the only continents with similar geology. Most all of the other continents fit together too.

The effect of hypoventilation, characterized by slow and shallow breathing, can have several implications for Sara's body and overall health. When someone hypoventilates, it means that their breathing rate and depth are insufficient to meet the body's oxygen demands and eliminate an adequate amount of carbon dioxide.

Reduced oxygen levels: Slow and shallow breathing leads to decreased oxygen intake, resulting in lower oxygen levels in the bloodstream. This can lead to tissue hypoxia, where organs and tissues may not receive enough oxygen to function properly.

Increased carbon dioxide levels: Insufficient breathing also impairs the removal of carbon dioxide from the body. As carbon dioxide accumulates in the bloodstream, it can lead to a condition called hypercapnia. This can cause respiratory acidosis, a state of increased acidity in the blood.

Altered pH balance: The accumulation of carbon dioxide and subsequent increase in acidity can disrupt the body's pH balance, potentially leading to acidemia, which is a condition of low blood pH.

Respiratory distress: Hypoventilation may result in respiratory distress, where the body struggles to maintain adequate oxygenation and eliminate carbon dioxide. This can lead to feelings of shortness of breath, fatigue, and discomfort.

It's important to note that hypoventilation can have various underlying causes, such as respiratory conditions, neurological disorders, or the use of certain medications. If Sara is experiencing hypoventilation, it is crucial for her to seek medical attention to identify the cause and receive appropriate treatment.

True,  there are only 2 places in which glucose is actively transported into the cell from the outside.

The method by which glucose is metabolised to produce energy is known as glycolysis. It generates water, ATP, NADH, and two pyruvate molecules. It doesn't need oxygen to happen because it happens in a cell's cytoplasm. Due to the fact that glucose is a carbohydrate, it cannot be a protein or a nucleic acid. An organic molecule makes it up. The organic molecule is a carbon-based substance to which hydrogen, oxygen, and nitrogen are bound. Considering that glucose is a simple sugar composed of carbon, hydrogen, and oxygen, it qualifies as an organic molecule along with all other forms of carbohydrate.

Answer:

The type of stem cells that can only develop into cells that are closely related to the original stem cell are called "unipotent" stem cells. These stem cells have the ability to differentiate into only one type of specialized cell, which is usually the same as the cell type from which they originated.

For example, a myoblast is a type of unipotent stem cell that can only develop into muscle cells. Similarly, a spermatogonial stem cell is a type of unipotent stem cell that can only develop into sperm cells.

Unipotent stem cells are different from "pluripotent" stem cells, which have the ability to differentiate into many different types of specialized cells. Pluripotent stem cells can give rise to cells from all three germ layers, which are the ectoderm, endoderm, and mesoderm. Embryonic stem cells and induced pluripotent stem cells are examples of pluripotent stem cells.

A smooth, sustained contraction resulting from very rapid stimulation of the muscle, in which no evidence of relaxation is seen, is called  fused tetanus.

Adjusting the frequency of muscle stimulation (i.e., going very quickly) causes a smooth, prolonged contraction known as fused tetanus (i.e., complete tetanus). Because there is no relaxation in between the individual twitches, it is smooth and not trembling.

When there is a fast rate of stimulation and there is no relaxation of the muscle fibres in between stimuli, this condition is known as fused tetanus. The strongest single-unit twitch in a contraction is a fused tetanic contraction. When tetanized, the muscle's steady-state contracting tension remains constant.

Hence, tetanus is sustained contraction due to successive signals.

Explanation:

In meiosis, homologous chromosomes separate in step a, which is called "anaphase I," and four haploid nuclei are formed in step b, which is called "cytokinesis II."

During anaphase I of meiosis, homologous chromosomes, which consist of one chromosome from each parent, separate and move toward opposite poles of the cell. This ensures that each resulting cell receives only one copy of each chromosome pair.

Anaphase I is a crucial step in meiosis as it ensures the distribution of genetic material between the daughter cells is randomized and contributes to genetic diversity.

Following anaphase I, the cell enters cytokinesis II, the second stage of cell division in meiosis. Cytokinesis II involves the physical separation of the two cells formed after anaphase I, resulting in the formation of four haploid nuclei, each containing a single set of chromosomes.

These nuclei go on to further undergo a process called "telophase II" to form four distinct haploid cells, known as gametes, which are essential for sexual reproduction.

Answer: By measuring the time it takes for P-waves and S-waves to arrive at different seismic stations, we can determine the distance from each station to the earthquake's epicenter. By triangulating these distances, we can pinpoint the epicenter.

Explanation: Seismographs will be used to record the arrival times of P-waves and S-waves at different seismic stations. By analyzing the time differences between the waves, we can calculate the distance to the earthquake's epicenter from each station. By triangulating these distances, we can pinpoint the epicenter of the earthquake. Therefore, we can determine the epicenter by triangulating the distances.

The P waves and S waves are used to determine the epicenter of an earthquake. Hypothesizing how seismographs will be used to pinpoint the epicenter of an earthquake involves the analysis of the behavior of the different types of waves.

Hence, a hypothetical explanation of seismographs to pinpoint the epicenter of an earthquake can be given as follows: In case an earthquake occurs, seismic waves spread out in all directions and are detected using seismographs. The primary waves (P waves) move faster and hence arrive first. The Secondary waves (S waves) follow the primary waves.

The time difference between the arrival of the P-waves and S-waves at each station can be used to locate the epicenter of the earthquake by measuring the distance to the epicenter. The distance between each station and the earthquake epicenter can be calculated based on the arrival time difference between P-waves and S-waves at each station.

The waves are detected by seismographs and by measuring the time difference, the distance between the seismic station and the epicenter can be determined. Using this method, three circles can be drawn around the station, each with a radius equal to the distance between the station and the earthquake epicenter. The intersection point of all three circles gives the exact location of the epicenter.

Therefore, the arrival times of P-waves and S-waves at different stations provide an efficient way to locate the epicenter of the earthquake.
