A researcher finds that blood alcohol levels cause progressive damage to the liver. All the mice in his study were fed the same amount and types of food. Different concentrations of alcohol were injected into each mouse. One group of mice does not receive any alcohol at all. The different concentration of alcohol injected into different mice represents the ______________________.

Answers

Answer 1
Answer: Independent variable, because it is not dependent on the other variables, because the researcher manipulates that variable and decides how much each mouse gets.

Draw a diagram of a virus and label the parts

Answers

Answer:

The diagram of the virus is given below.

Explanation:

Virus may be defined as the simple organism that contain DNA or RNA as their genetic material, surface area is covered with protein coat. Body is divided into head, neck collar and tail fibers. Virus requires a host organism for its growth and reproduction. Virus can affect plants, animals, bacteria and microorganisms.

Viruses are very small, typically between 20 and 300 nanometers in diameter and  are so small that they can only be seen with an electron microscope.

How do we explain?

Viruses are not considered to be living organisms because they do not have their own metabolism. They need to infect a host cell in order to reproduce. Once a virus infects a host cell, it takes over the cell's machinery and uses it to make more copies of itself.

Viruses can cause a wide variety of diseases, including the common cold, the flu, and AIDS. There is no cure for most viral diseases, but there are treatments that can help to relieve the symptoms.

In a forest, a tree falls on a swamp and kills the worm population reducing the population by half. The remaining population is characterized by a remarkable reduction in genetic diversity. Which mechanism of evolution is exhibited here?

Answers

The mechanism of evolution that has been exhibited here is known as bottleneck effect. The fact that a sudden incident of the tree falling caused the death of rare alleles and this resulted in the decrease in genetic diversity of the population. I hope that this is the answer you were looking for and it has helped you.
bottleneck effect is the answer on plato

What determines the differences between the way men and women speak?

Answers

Testosterone! Hormones jn general make a large difference

Final answer:

Differences between the way men and women speak are largely culturally determined, though early research suggested they were due to societal socialization. Modern research indicates the impact of linguistic determinism - the way one's languages can influence one's thoughts and perceptions. Importantly, these gendered speech patterns are not a universal biological fact, but vary across different cultures.

Explanation:

Various factors, predominantly cultural and social, contribute to the differences between men's and women's speech. Early research theories such as those from Robin Lakoff suggested that societal socialization resulted in women's speech being seen as uncertain, excessively polite, and full of hedges. Likewise, Deborah Tannen argued that men and women communicate differently, with men focusing more on status and women on building connections through conversation.

However, more recent studies argue against this concrete division. Janet Hyde, challenging traditional gender role-based speech patterns, conducted a comprehensive analysis which showed minimal differences in verbal skills between boys and girls. Similarly, language research on cultural aspects from Madagascar and New Guinea reveal that speech patterns associated with gender are indeed culturally relative.

Another relevant factor is the role of linguistic determinism, which suggests that the language one speaks can significantly influence one’s thoughts and perceptions. This idea was demonstrated in Lera Boroditsky's research, that native German and Spanish speakers, in which nouns are gendered, describe things differently depending on the noun's gender in their language, even when communicating in a gender-neutral language such as English.

In conclusion, while there may be some observable differences in the way men and women speak, gendered speech patterns are largely cultural and vary significantly across different societies, and they cannot be generalized or naturalized as biological phenomena.

Why are annual temperature ranges in the Southern Hemisphere generally smaller than those in the Northern Hemisphere?

Answers

Annual temperature ranges in the Southern Hemisphere generally smaller than those in the Northern Hemisphere because there is a higher rate of the water surface in the Southern Hemisphere.

Water is a prominent absorber of radiation and slower radiator of heat than land Environments in the southerly region which overall tend to be lightly moderate than those in the northerly region. This is because the southerly hemisphere has significantly more beach and less land. Water warms up and freezes down more slowly than land. The southerly hemisphere is also significantly less contaminated than the northerly hemisphere because of lower population densities,  lower levels of industrialization, and smaller land sizes.

Why are Annual temp ranges in the southern hemisphere generally smaller than those in the northern hemisphere? Answer:there is more water
