After several miles of running and sprinting in intervals, the runner’s muscles ache and feel fatigued. Which is the best explanation for what has occurred?

Answers

Answer 1

After miles of running and sprinting in intervals, the runner's muscle ache and feel fatigue due to anaerobic respiration taken place in the muscle cells.Anaerobic respiration in animal cell gives Carbon Dioxide and lactic acid as products. Due to the formation of lactic acid after running, muscles feel fatigue and ache.
I hope I helped you! ^^

Answer 2

When your muscles don't have enough oxygen for the exercise they're doing they have to break down carbohydrates into something called lactic acid. Lactic acid also increase the acidity of the muscle cells, so it makes your muscles sore. It may seem counterproductive for your body to produce something that would make your muscles not function as well, but without the lactic acid permanent damage could could happen because your muscles wouldn't be getting the oxygen they need.

Let me help you!
Using the visual you provided, the correct sequence is:
Sequence one: The double-stranded DNA virus then enters the nucleus and integrates itself into the host's DNA.

Sequence two: after the retrovirus entered, the enzyme reverse transcriptase uses the RNA as atemplate to make a double-stranded viral DNA module.

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.

Answers

Hardy-Weinberg Principle

Genotype frequency equation

Where p² is the freq of homo dominant genotype, 2pq is the freq of heterozygous genotype and q² is the freq of homo recessive genotype.

Allele frequency equation

p + q = 1

Where p is the frequency of dominant alleles and q is the frequency of recessive alleles.

Yellow eyes in the frog offspring is a phenotype (physical trait) that would be a expressed by a geneotype (YY or Yy). This frequency, 0.85 includes: p² + 2pq

0.85 + q² = 1

q² = 0.15

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.

Ocean water is sinking at the North Atlantic Buoy Station. What could be the reason that the water sinks?

A. Warmer water sinks below cold water.

B. Denser water sinks below less dense water.

C. Freshwater sinks below ocean water.

D. Water of low salinity sinks below water of high salinity.

Answers

A. false. Colder water sinks because its denser. It's particles are closer together due to the temperature.
B. True. Liquids of higher density sink.
C. False. Seawater is denser than freshwater due to the salt particles in it
D. False. The higher the salinity, the higher the density. High salinity means there's more salt mixed into a specified volume. The more particles in a specified volume, the higher the density.
Your answer is B

The reason that the water sinks is : ( B ) Denser water sinks below less dense water

Water density

The denser a water body becomes the more likely it will sink also the increase in solute content ( salinity ) a water contains, the denser the water becomes.

Therefore a water of high salinity will be more dense than a water with low salinity because of the increased amount of solute it contains.

Hence we can conclude that the reason that the water sinks is Denser water sinks below less dense water.

In the dog and cat, sesamoid bones are found in joint between metacarpal bone and first phalanx.
sesamoid bone is a independent bone nodule that developed in a tendon where it passes over an angular structure. The bones are commonly found in the portions of metacarpal bones

Sesamoid bones, like the patella, are found within tendons near joints such as the knees, hands, and feet in both dogs and cats. They help in protecting the tendons and improving mechanical function at these joints.

In dogs and cats, sesamoid bones are typically found embedded within tendons near joints, particularly at the knees, hands, and feet. An example of a sesamoid bone that is common in both animals and humans is the patella (kneecap). The primary function of sesamoid bones is to protect tendons from compressive forces and improve the mechanical function of the joints they are associated with. These bones are small, flat, and are named due to their resemblance to a sesame seed. Although the number and exact placement can vary between individuals, they are always associated with tendons, especially in areas subjected to high pressure or tension.

Answering the specific question posed, in the context of the options provided (a. flat bones, b. short bones, c. sesamoid bones, d. irregular bones) in section 8 of the textbook, the correct choice is c. sesamoid bones.
