Final answer:

Abusing amphetamines by using them to counteract depressant effects can lead to increased tolerance, psychological dependence, and severe health risks.

Explanation:

A common form of abuse of amphetamines that is damaging to the body is using amphetamines to counteract the effects of depressants taken the night before ( option A ). This practice can severely disrupt the body's natural processes, leading to increased tolerance and a dangerous psychological dependence on amphetamines. Amphetamines work by blocking the reuptake of neurotransmitters like dopamine, similarly to how cocaine works, but also stimulate their release, increasing the activity of the sympathetic nervous system.

This results in heightened alertness and energy, but also increases heart rate and blood pressure, which can be harmful over time. Furthermore, using amphetamines in this manner can lead to a dangerous cycle of dependency and intense withdrawal symptoms, such as severe psychological depression.

How many codons code for the amino acid arginine?

Answers

Answer:

The number of codons that code for arginine are six: CGU, CGC, CGA, CGG, AGA, and AGG. Where C = cytosine, G = guanine, U = uracil, A = adenine.

Explanation:

Arginine is a fundamental amino acid for the body and is part of the proteins. It is found in red meat, in poultry meat and in dairy products, and stimulates the function of the immune system, increasing leukocytes. In addition, it is involved in the production of creatine. In messenger RNA it is encoded by six codons: CGU, CGC, CGA, CGG, AGA, and AGG.

Final answer:

Arginine, an amino acid, is coded for by six different codons - CGU, CGC, CGA, CGG, AGA, and AGG. The redundancy of the genetic code allows multiple codons to code for the same amino acid, mitigating the effects of mutations on protein coding. The number of codons coding for an amino acid can vary, with some being coded by single codons while others by multiple codons.

Explanation:

The amino acid arginine is coded for by six different codons. These codons are CGU, CGC, CGA, CGG, AGA, and AGG. This aspect is part of the redundancy of the genetic code, which means that multiple codons can code for the same amino acid.

This redundancy is helpful in reducing the impact of mutations. For instance, if a mutation changes the codon CGU to CGC, it would still code for the same amino acid - that is, Arginine. Hence, the effect of such a mutation would be mitigated.

It's essential to note that how many codons code for an amino acid varies for different amino acids. Some amino acids are encoded by a single codon, while others, like Arginine, are encoded by multiple codons.

Appositional growth is the type of cartilage growth that involves stem cells at the internal edge of the perichondrium dividing, differentiating into chondrocytes, and creating new cartilage at the periphery.

Explanation:

The type of cartilage growth being asked about is called appositional growth. This process involves stem cells at the internal edge of the perichondrium, a layer that surrounds the cartilage, dividing and differentiating into chondrocytes, the cells that make up cartilage. These newly formed chondrocytes then produce new cartilage at the periphery, expanding the cartilage outward. This type of growth allows a cartilage structure to increase in diameter and thickness.

The type of cartilage growth in which stem cells at the internal edge of the perichondrium divide, differentiate into chondrocytes, and create new cartilage at the periphery is called "appositional" growth.

Cartilage is a specialized connective tissue that can grow and adapt in two primary ways: appositional growth and interstitial growth. Here, we focus on appositional growth.

Appositional growth involves the addition of new cartilage tissue to the surface or periphery of existing cartilage. It occurs in the following manner:

1. Stem cells located in the inner layer of the perichondrium (a connective tissue membrane surrounding cartilage) divide and differentiate into chondroblasts.

2. Chondroblasts secrete the extracellular matrix of cartilage, composed of collagen and proteoglycans, which gradually hardens.

3. As the matrix hardens, the chondroblasts within it become mature chondrocytes, the cells responsible for maintaining the cartilage.

4. New layers of cartilage are added to the existing cartilage, increasing its thickness and size over time.

Appositional growth allows cartilage to expand and adapt, particularly during periods of growth or in response to mechanical stress, helping to maintain tissue integrity and function.

Seasonal variations in ocean temperatures can impact the populations of living organisms in the ocean. How would a phytoplankton population be affected by these changes?

Answer:Lower ocean temperatures allow for phytoplankton to bloom, which increases the phytoplankton population.

Answers

A phytoplankton population would be affected by these changes by increasing the population of the phytoplankton. Low temperature of the ocean would allow for the phytoplanktons to bloom or reproduce. Therefore, high temperatures would slow down growth. This is because when water is warm there would be less mixing between the water layers and the nutrient rich water.

Answer:

Explanation:

These modifications would have an impact on a phytoplankton community by boosting the phytoplankton population. The ocean's cool temperature would enable phytoplanktons to flourish or proliferate. Therefore, growth would be slowed by high temperatures. This is due to the fact that warm water would mix less with the water that is nutrient-rich layers.

The most effective way to utilize abs brakes is to

Answers

Anti lock Braking System [ABS] is an automobile safety system that allows the car wheels to make tractive contact with the road road surface in response to the driver's command. It prevents the wheel from locking up and the car from skidding. The most effective way to utilize ABS is to depress the brake pedal firmly until you regain the control of the vehicle. The principal aim of the ABS is to help one regain the control of one's car during panic stop.

Final answer:

To effectively use ABS brakes, apply steady pressure to the brake pedal and allow the ABS system to modulate braking force, preventing wheel lock and allowing for steering control.

Explanation:

The most effective way to utilize ABS brakes is to apply steady pressure to the brake pedal and allow the system to modulate the braking force to prevent the wheels from locking. This helps maintain steering control during an emergency stop or when braking on slippery surfaces. ABS systems, like those used in large vehicles such as trucks, work by converting gravitational potential energy into increased internal energy (higher temperature) of the brake material, which controls the speed without converting it into kinetic energy that would increase the truck's velocity.

Therefore, rather than pumping the brakes, drivers of ABS-equipped vehicles should apply constant, firm pressure on the brake pedal during a stop. ABS works best under these conditions because the system can adjust the braking force more rapidly than a driver can. This method helps prevent the wheels from locking and enables drivers to maintain control over the direction of the vehicle, which is particularly vital during sudden stops or on slippery roads.
