Answers
Anyone involved in the drug trade who was subject to the Harrison Act was required to register yearly and pay an additional $1 annual tax.
What prohibited by the Harrison Act?Congress passed the Harrison Act, which outlawed cocaine and opiates, in 1914. Alcohol prohibition soon followed, and by 1918, the United States had become a "dry" country. However, it did not indicate that drug use would stop.By whom is the Harrison Act enforced?In the US, a drug division was created. It was the Treasury Department that put a stop to all drug sales. By the middle of the 1920s, there was more demand for pharmaceuticals on the black market, indicating that the Harrison Act had really had an impact on the supply of narcotics.

two humans mate. one is heterozygous for achondroplastic dwarfism (tt) while the other is homozygous for normal length limbs (tt). what are the possible phenotypic outcomes of this mating?
Answers
In this scenario, the offspring will not have achondroplastic dwarfism, but there is a possibility that they may pass on the gene to their own offspring in the future.
In this scenario, the heterozygous parent carries one copy of the achondroplastic dwarfism gene (t) and one copy of the normal gene (T). Meanwhile, the homozygous parent carries two copies of the normal gene (TT).
When the two parents mate, their offspring will inherit one copy of a gene from each parent. Therefore, the possible combinations of genes that their offspring could inherit are:
- Tt (normal length limbs, carrier of the achondroplastic dwarfism gene)
- Tt (normal length limbs, carrier of the achondroplastic dwarfism gene)
- TT (normal length limbs, not a carrier of the achondroplastic dwarfism gene)
- TT (normal length limbs, not a carrier of the achondroplastic dwarfism gene)
This means that there are two possible phenotypic outcomes for the offspring:
1. Normal length limbs: If the offspring inherits two copies of the normal gene (TT), they will have normal length limbs and will not be a carrier of the achondroplastic dwarfism gene.
2. Carrier of the achondroplastic dwarfism gene: If the offspring inherits one copy of the normal gene (T) and one copy of the achondroplastic dwarfism gene (t), they will have normal length limbs but will be a carrier of the achondroplastic dwarfism gene.
It is important to note that achondroplastic dwarfism is a dominant genetic disorder. This means that if an individual inherits one copy of the achondroplastic dwarfism gene, they will have the disorder. However, if an individual inherits two copies of the achondroplastic dwarfism gene (tt), they will have a more severe form of the disorder.

Plane joints are numerous and are nearly always small, such as the acromioclavicular joint between the acromion of the scapula and the clavicle. Typically, they are found in the wrists, ankles, the 2nd through 7th sternocostal joints, vertebral transverse and spinous processes.
TRUE OR FALSE?
Answers
True
Explanation:
The statement is true. Plane joints, also known as gliding joints, are joints that allow for a sliding or gliding motion between two flat surfaces. They are generally small and occur between bones that are closely aligned with each other. The acromioclavicular joint between the acromion of the scapula and the clavicle is an example of a plane joint. Other examples of plane joints include those found in the wrists, ankles, and sternocostal joints between the second and seventh ribs. Additionally, plane joints are found between the transverse and spinous processes of the vertebrae. These joints are relatively simple in structure and do not allow for significant movement in any one direction. Instead, they permit limited movement in multiple directions, such as twisting, bending, or sliding.

Why do many species of algae appear green?
The chlorophyll pigment they contain is green
Heterotrophs would not be able to use autotrophs as an energy source.
This organism is both a heterotroph and an autotroph.
Answers
Many species of algae appear green because of the chlorophyll pigment they contain, which is green. The correct option is the chlorophyll pigment they contain is green.
This pigment is responsible for capturing sunlight and converting it into energy through the process of photosynthesis. Algae, being autotrophic organisms, produce their own food through photosynthesis. This is essential for their survival since heterotrophs would not be able to use them as an energy source.
Interestingly, some species of algae are both autotrophs and heterotrophs, meaning they can produce their own food through photosynthesis but can also consume other organisms for additional nutrients.
Many species of algae appear green because they contain chlorophyll pigments that give them a green color. Chlorophyll is the primary pigment involved in photosynthesis, the process by which organisms convert light energy into chemical energy.
It absorbs light primarily in the red and blue regions of the electromagnetic spectrum, while reflecting or transmitting light in the green region. As a result, algae appear green to our eyes.
The ability to photosynthesize is crucial for algae, as it allows them to produce their own food by converting sunlight, carbon dioxide, and water into glucose and oxygen. This autotrophic mode of nutrition provides algae with a reliable energy source, enabling their growth and survival.
Heterotrophs, on the other hand, cannot produce their own food through photosynthesis. They rely on consuming other organisms or organic matter for energy.
Therefore, while heterotrophs cannot directly use algae as an energy source, they can indirectly benefit from algae by consuming organisms that feed on algae or by consuming organic matter derived from algae.
It is worth noting that while some organisms, such as certain types of algae, can exhibit both autotrophic and heterotrophic characteristics depending on environmental conditions, the majority of algae are primarily autotrophs.
The correct option is the chlorophyll pigment they contain is green.

you see a bear in the woods and are immediately afraid. what area of the brain detected this fear?
Answers
When you see a bear in the woods and are immediately afraid, it is your amygdala that detects this fear. The amygdala is a small, almond-shaped structure located deep in the brain's temporal lobe.
It plays a crucial role in processing emotions, particularly fear and anxiety. As soon as you see the bear, the amygdala sends a signal to your hypothalamus, which triggers the release of adrenaline and other stress hormones. These hormones prepare your body for the "fight or flight" response, which allows you to respond to the danger quickly and effectively. The amygdala's ability to process fear quickly and efficiently is essential for our survival. Without it, we would not be able to react to threats in time to avoid harm. However, sometimes the amygdala can be overactive, leading to excessive fear and anxiety. This can be a symptom of anxiety disorders such as PTSD, phobias, and panic attacks. In conclusion, the amygdala is the area of the brain that detects fear when you see a bear in the woods, triggering the "fight or flight" response that prepares your body to respond to danger.

scientists estimate that whaling activity in the 19th and early 20th centuries had reduced the number of adult female southern right whales to as few as sixty individuals by 1920. this reduction resulted in a genetic bottleneck for the species. treaties to stop whaling have substantially increased the number of southern right whales. despite this increase, the bottleneck still threatens the future of the species. which capacity of the species is most severely diminished by the bottleneck?
a. acquiring random mutations
b. responding to environmental changes
c. maintaining a healthy social structure
d. remaining genetically stable.
Answers
The capacity of the southern right whale species that is most severely diminished by the bottleneck is the ability to remain genetically stable and maintain a diverse gene pool.
A genetic bottleneck is a reduction in the size of a population that leads to a loss of genetic diversity. This can occur due to a number of factors, including natural disasters, disease outbreaks, or human activities such as hunting or habitat destruction. In the case of the southern right whales, the population was severely reduced by whaling activity in the 19th and early 20th centuries, leading to a genetic bottleneck. The capacity of the species that is most severely diminished by the bottleneck is the ability to maintain a diverse gene pool, which is necessary for the species to adapt to changing environmental conditions and respond to new challenges. When a population experiences a genetic bottleneck, the number of different genes available for selection is reduced, leading to a loss of genetic diversity. This can make it more difficult for the population to adapt to new challenges and can increase the risk of extinction.

chegg assume an aneurysm has widened a blood vessel from a diameter of 1 cm to a diameter of 4 cm. what is the velocity v1 of blood flow in the region of the aneurysm relative to the velocity v0 in the healthy portion of the blood vessel.
Answers
According to the equation, the total pressure in the flow is equal to the sum of the static pressure (ps) and dynamic pressure (pd), which is equal to one-half of the density (r) times the velocity (V) squared.
This constant is known as the flow's overall pressure, or pt. According to Bernoulli's principle, which governs fluid dynamics, a fluid's speed increases concurrently with a reduction in pressure or potential energy. The mathematical concept is named after Swiss mathematician Daniel Bernoulli, who first published it in his book Hydrodynamics in 1738. The pressure difference between two measurements is denoted by the symbol P. This can be assessed at several points within a system or at various times/dates. The measurement can vary depending on the situation.

Which ion is a found in a glass of water
Answers
In a glass of water, the most common ion found is the hydroxide ion (OH-) and the hydrogen ion (H+).
These ions are formed when water molecules dissociate through a process called self-ionization or autoionization.
In a glass of water, several ions can be found, originating from the dissociation of water molecules. The main ions present are hydrogen ions (H+) and hydroxide ions (OH-), resulting from the self-ionization of water.
Water molecules can break apart spontaneously into equal concentrations of H+ and OH- ions through a process called autoionization. This occurs when a water molecule donates a proton (H+) to another water molecule, forming H3O+ (hydronium ion) and OH-.
Additionally, other ions might be present in a glass of water depending on its source. For example, tap water can contain various dissolved ions like calcium (Ca2+), magnesium (Mg2+), sodium (Na+), chloride (Cl-), and bicarbonate (HCO3-). These ions come from minerals and other substances present in the water source, such as groundwater or surface water.
It's worth noting that the specific ion composition of water can vary depending on factors like location, treatment processes, and water source. However, the fundamental ions present in water are H+ and OH- resulting from the autoionization of water molecules.

Answers
The statement "For every bacterial cell that undergoes sporulation, there are two resulting bacterial cells" is false. Sporulation is a process where some bacteria transform into a dormant state called a spore. Only one spore is produced per bacterial cell during sporulation.
Bacterial sporulation is a process where some bacteria convert to a dormant state called a spore. Sporulation can occur in some bacteria species under stress conditions such as a lack of nutrients. Sporulation starts when the bacterial cell divides into two unequal-sized compartments. One compartment is the smaller forespore while the other is the larger mother cell.
The mother cell engulfs the forespore within itself and forms a spore. Only one spore is produced per bacterial cell during sporulation. These spores can survive in harsh environments and then germinate into new bacterial cells when conditions are favorable again. Therefore, the statement "For every bacterial cell that undergoes sporulation, there are two resulting bacterial cells" is false.
