what is the function of the Vaseline

Answers

Answer:

Chesebrough noticed that oil workers would use a gooey jelly to heal their wounds and burns. He eventually packaged this jelly as Vaseline.

25. How do the excretory systems of animals that secrete uric acid differ from those of animals that excrete urine?
34. Explain why maintaining water balance is part of the process of excreting nitrogenous wastes.

thanks!!

Answers

Answer:

25.Nitrogenous wastes in the body tend to form toxic ammonia, which must be excreted. Mammals such as humans excrete urea, while birds, reptiles, and some terrestrial invertebrates produce uric acid as waste. Uricothelic organisms tend to excrete uric acid waste in the form of a white paste or powder.

34.The excretory system removes cellular wastes and helps maintain the salt-water balance in an organism. In providing these functions, excretion contributes to the body's homeostasis, the maintenance of constancy of the internal environment. When cells break down proteins, they produce nitrogenous wastes, such as urea

Which explains why secondary succession generally occurs more rapidly in an area than does primary succession?

A) Average precipitation is higher
B) Moderate climatic conditions exist
C) Pioneer species are microscopic
D) Soil formation has already occurred

Answers

Answer:

Secondary succession usually occurs faster than primary succession because the substrate is already present. In primary succession, there is no soil and it needs to form. This process takes time, as pioneer species must colonize the area, they must die, and as this happens over and over again, soil forms.

Physiologists work to understand how the body operates under normal conditions and how the body adapts to survive under unstable conditions.

A placebo is a fake treatment that mimics the experience of the experimental group.
true
false

Answers

Answer:

true

Explanation:

Doctors (or scientists) usually use this to make sure people aren't lying about the experience.

For example, some people might expect that if they take ibuprofen or Tylenol, they won't feel as much pain, so they might make themselves believe that they aren't feeling said pain. If you use a placebo group, you are less likely to have situations like that occur, and so your data becomes more accurate.

Describe the natural environment of the species in terms of abiotic and biotic factors,

Answers

Answer:

Abiotic and biotic factors make up an ecosystem. Abiotic factors are the non-living parts of an environment. These include things such as sunlight, temperature, wind, water, soil and naturally occurring events such as storms, fires and volcanic eruptions. Biotic factors are the living parts of an environment, such as plants, animals and micro-organisms.

Together, they are the biological factors that determine a species' success. Each of these factors impacts others, and a mix of both is necessary for an ecosystem to survive.
