Eleanor is testing how temperature affects the hatching of chicken eggs. She has three groups of eggs, one each at 25°C (77°F),

30°C (86°F), and 35°C (95°F). In this experiment, temperature is the _____ variable.

It's then independent variable.

This is the case because Eleanor is making these temperature changes.

Extra info.

The dependen variable would then be the result of hatching. This is the case because it depends on the different temperature to see what the effect of temperature change is affecting the time of hatching

Andru [333]

Answer: ecosystem

An ecosystem is a community of living and non-living components. A coral reef is an aquatic ecosystem which is formed by a continuous walls of calcium carbonates released by living animals they get combine to form rocks. These rocks and walls are collectively called as hard stony corals. These hard stony corals provide shelter to many aquatic animals like fishes. As the water is the chief abiotic factor along with coral walls and rocks which help in the survival of living organisms therefore, ecosystem is the largest organizational level found in one coral reef.

Assume that you touch poison sumac and still have not developed a rash 12 hours later. Can you safely assume you are not allergi
katrin2010 [14]
The first time you get poison sumac, it usually takes a while to show up. If you have had it before, it takes around a day or two if you have had it before, so I'd say the answer to the question is no.

Answer: It was obtained 8515 years ago

Explanation:

Expression for rate law for first order kinetics is given by:

t=\frac{2.303}{k}\log\frac{a}{a-x}

where,

k = rate constant

t = age of sample

a = let initial amount of the reactant

a - x = amount left after decay process  

a) to find the rate constant:

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

t_{\frac{1}{2}}=\frac{0.693}{k}

k=\frac{0.693}{5760}=0.00012years^{-1}

b) for completion of 36% of reaction

t=\frac{2.303}{k}\log\frac{100}{36}

t=\frac{2.303}{0.00012}\log\frac{100}{36}

t = 8515 years

The time was 8515 years.
