increased blood pressure is primarily an effect of the sympathetic nervous system (SNS). The SNS is responsible for the "fight or flight" response, which includes increased heart rate and blood pressure in order to prepare the body for perceived danger or stress.

the SNS releases the hormone adrenaline, which causes blood vessels to constrict and the heart to beat faster and harder. This results in an increase in blood pressure. Additionally, the SNS also signals the kidneys to release the hormone renin, which leads to an increase in blood volume and further raises blood pressure.

On the other hand, the parasympathetic nervous system (PSNS) has the opposite effect on blood pressure. The PSNS is responsible for the "rest and digest" response, which includes a decrease in heart rate and blood pressure in order to conserve energy and promote relaxation.

while both the SNS and PSNS play a role in regulating blood pressure, increased blood pressure is primarily an effect of the SNS. This is due to the SNS's activation of the "fight or flight" response and release of adrenaline, which leads to increased heart rate, blood vessel constriction, and blood pressure.
Main Answer: Increased blood pressure is an effect of the Sympathetic Nervous System (SNS).

The Sympathetic Nervous System (SNS) is responsible for the body's "fight or flight" response. When activated, it increases heart rate, constricts blood vessels, and raises blood pressure to prepare the body for action. On the other hand, the Parasympathetic Nervous System (PSNS) is responsible for the body's "rest and digest" response, helping the body to relax, conserve energy, and decrease heart rate and blood pressure.

The Sympathetic Nervous System (SNS) causes increased blood pressure as part of the body's stress response, while the Parasympathetic Nervous System (PSNS) works to decrease blood pressure during periods of relaxation.

The presence of limb buds with homologous bones in dolphin embryos provides evidence of their 4-legged ancestors.

la. The earbone found in the deerlike mammal fossil of Indohyus looked very similar to the earbone of a modern whale.

lb. The scientific definition of evolution is the process by which different species of living organisms develop and change over time, typically through genetic variation and natural selection.

lc. The six different lines of evidence for evolution are artificial selection, fossil evidence, biogeography, anatomical evidence, molecular evidence, and the observed evolution of species in real time.

2a. Selective breeding, also known as artificial selection, is the process of humans intentionally breeding plants or animals with desirable traits in order to produce offspring with those same traits.

2b. In artificial selection, humans do the selection.

2c. Natural selection is the process by which certain traits become more or less common in a population over time, based on their impact on survival and reproduction in a particular environment.

2d. In natural selection, the environment and its selective pressures do the selecting.

2e. In the Galapagos finch adaptation example, the change in the environment was a drought that led to a shortage of small seeds. The selective agent was the availability of larger, tougher seeds, which determined who survived to reproduce. The variation present in beaks was the natural range of sizes and shapes among finches. The adaptation that resulted from the selective pressure was a change in beak size and shape to better match the available seeds.

2f. According to a 2019 poll, about 40% of adults in the USA do not believe that humans evolved from earlier species of animals. Evolution is supported by a vast amount of evidence, from the fossil record to molecular biology, and is widely accepted as the scientific explanation for the diversity of life on Earth.

3a. A fossil is the remains or traces of an ancient organism that have been preserved in the Earth's crust.

3b. A transitional fossil is a fossil that shows characteristics of two different groups of organisms, indicating that it represents an intermediate stage in the evolution of one group into another.

3c. Thewissen's team concluded that Indohyus lived near water, based on the structure of its teeth, which suggested it ate aquatic plants.

3d. By studying the molars of Indohyus, Thewissen's team concluded that it ate a fibrous diet of aquatic plants.

3e. The thick bone of Indohyus's leg was adaptive because it allowed it to support its weight while walking and wading in water, and to dive without breaking its legs.

3f. Rat, Hippopotamus, and Manatees have thick bones similar to those of Indohyus.

3g. Being able to wade and dive would have given Indohyus an advantage in foraging for aquatic plants and escaping predators.

4a. Species share similar features, or homologous traits because they inherited them from a common ancestor.

4b. Vestigial traits are remnants of features that were useful to an organism's ancestors but have lost their function in the current organism. They are present in species because they are "leftover" from their evolutionary history.

4c. The two vestigial traits found in whales are their hind limb bones and their pelvic bones.

5a. The genetic code is evidence supporting the conclusion that all living things share a common ancestor because it is essentially the same in all organisms, with minor variations.

5b. DNA evidence suggests that whales are most closely related to the group of mammals called Artiodactyla, which includes cows, pigs, hippos, and deer.

5c. DNA evidence suggests that whales are most closely related to the hippopotamus.

6a. Plate tectonics plays a crucial role in shaping the patterns we see in the fossil record and the evolution of species. It explains how continents and oceans have shifted and collided over millions of years, resulting in the formation of new land masses, mountains, and oceanic basins.

6b. The fossils of Pakicetus, an early species in the whale lineage, are found only near India and Pakistan because these areas were once a shallow sea, known as the Tethys Sea, that connected the Indian Ocean to the Mediterranean Sea.

The retrovirus HIV (Human Immunodeficiency Virus) is unlike other single-stranded, positive-sense (+) RNA viruses in that it is a single-stranded, reverse-transcribing RNA virus.

This means that HIV carries the enzyme reverse transcriptase, which converts its RNA genome into DNA upon entering the host cell. In contrast, positive-sense (+) RNA viruses typically translate their RNA genomes directly into proteins without undergoing the reverse transcription step.

A retrovirus is a type of virus that alters a cell's genome by inserting a DNA copy of its RNA genome into the DNA of the host cell it infects.  The virus employs its own reverse transcriptase enzyme to create DNA from its RNA genome after entering the cytoplasm of a host cell, which is the opposite of the normal pattern and is referred to as retro. An integrase enzyme then incorporates the new DNA into the host cell's genome; at this point, the retroviral DNA is referred to as a provirus.

A cell spends most of its time in the Interphase stage of the cell cycle. Interphase consists of three sub-stages: G1 (Gap 1), S (Synthesis), and G2 (Gap 2). During the G1 phase, the cell grows, carrying out its regular functions, and preparing for DNA replication. In the S phase, DNA replication occurs, duplicating the genetic material. The G2 phase involves further growth and preparation for cell division (mitosis).

Interphase is the longest part of the cell cycle, accounting for approximately 90-95% of the total cycle time. This extended duration allows the cell to carry out its specific functions, maintain homeostasis, and ensure accurate DNA replication. By contrast, the remaining stages of the cell cycle (Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis) are collectively called Mitosis, which involves the actual division of the cell and its genetic material.

The number of cells observed in each stage can vary depending on the cell type and organism. However, in general, a larger proportion of cells are found in Interphase, reflecting the longer time spent in this stage compared to the other stages of the cell cycle.

The two-factor theory of PTSD states that first fear is created, and then maintained.

The two-factor theory of PTSD is a psychological model that explains the development and maintenance of post-traumatic stress disorder (PTSD). According to this theory, PTSD is formed through a two-stage process: fear creation and fear maintenance.

In the first stage, fear is created when an individual experiences a traumatic event, such as an accident, natural disaster, or violence. The intense emotions and physiological responses associated with the trauma lead to the formation of strong associations between the event and the fear response. This process is known as classical conditioning, where a previously neutral stimulus becomes associated with a negative emotional response.

In the second stage, fear maintenance, these strong associations between the traumatic event and the fear response continue to be reinforced. This reinforcement can occur through operant conditioning, which involves the avoidance or escape from anxiety-provoking stimuli related to the trauma. As the individual continues to avoid or escape these situations, they unintentionally strengthen the connection between the traumatic event and their fear response. This leads to the ongoing experience of PTSD symptoms, such as intrusive memories, hyperarousal, and negative alterations in mood and cognition.

In summary, the two-factor theory of PTSD posits that the disorder develops through a two-stage process: the creation of fear in response to a traumatic event, and the maintenance of that fear through reinforcement via avoidance or escape behaviors. Understanding this process can be crucial for the development of effective treatment approaches aimed at reducing PTSD symptoms and promoting recovery.

A change from UAU to UAC would be a silent mutation since both codons code for the same amino acid, tyrosine. On the other hand, a change from UAU to UAG would be a nonsense mutation since UAG is a stop codon and would terminate the translation process prematurely.The correct option is B.


The genetic code is composed of nucleotide triplets called codons that code for specific amino acids during protein synthesis. There are 64 possible codons and some code for the same amino acid. UAU and UAC both code for tyrosine, which means a change from UAU to UAC would be a silent mutation. Silent mutations do not change the amino acid sequence of the resulting protein.

However, a change from UAU to UAG would be a nonsense mutation because UAG is a stop codon and would cause premature termination of the translation process. Nonsense mutations can result in nonfunctional proteins or truncated proteins that may have altered functions.


Therefore, the correct answer is b. nonsense; silent.

After mitosis, each daughter cell receives a complete set of genetic information that is identical to the original cell. This means that 100% of the original cell's genetic information can be found in each daughter cell.

Mitosis is the process by which a cell divides into two identical daughter cells, and it ensures that each daughter cell receives a complete and identical copy of the genetic material. This is important for maintaining genetic stability and ensuring that the cells can carry out their functions properly.

Mitosis is a complex process that involves several stages, including prophase, metaphase, anaphase, and telophase. Each stage plays an important role in ensuring that the genetic material is properly separated and distributed between the daughter cells.

Overall, mitosis is a critical process for growth, development, and repair in multicellular organisms, and it ensures that each new cell has a complete and accurate copy of the genetic information.
