How can you use a fossil to indemnify the environment where the organism lived

Chemistry

Vedmedyk [2.9K]3 years ago

Climate is one of the factors that determines where different species of plants and animals can live, so paleontologists look for clues to a location's ancient climate in the types of fossil plants and animals they find there. For example, no modern crocodile species lives in a climate with long periods of freezing temperatures, so scientists hypothesize that ancient crocodiles had the same requirement for year round warmth. That leads them to consider the 110-million-year-old crocodile fossils from the Washington, D.C. to be part of a large body of circumstantial evidence that temperatures there were warm year round during the Early Cretaceous. Similarly, coal beds and fossil trees in the Arctic Slope of Alaska are among the many clues that Alaskan temperatures were very warm during the Late Cretaceous.

Some metals corrode very readily. Metals from which groups might be used to provide a protective coating? Justify the answer
Andreyy89

Explanation:

Cadmium, nickel, chromium, and silver are sometimes used as protective platings. Metals have a wide range of corrosion resistance. The most active metals (i.e., those that tend to lose electrons easily)--such as magnesium and aluminum--corrode easily and are listed at the top of Table 2-1.

A urine sample has a mass of 147 g and a density of 1.020 g/mL. What is the volume of this sample?
son4ous [18]

So we know that the equation for density is:

D=\frac{m}{V}

where D is the density, m is the mass in grams, and V is the volume in mL.

So since we know two of the variables, mass and density, we can solve for the volume:

\frac{1.020g}{mL}=\frac{147g}{V}

V=\frac{147g}{\frac{1.020g}{mL}}

V=144.12mL

Therefore, the volume of this urine sample is 144.12mL.

Niels Bohr's model of the hydrogen atom was controversial because _________.a. it contradicted accepted principles of physics. b
Tju [1.3M]

Answer:

The correct answer to the question is

a. it contradicted accepted principles of physics

Explanation:

The idea of electrons moving in orbits contradict classical electromagnetism idea whereby electrons are expected spiral to the nucleus instantaneously. Meaning all atoms are supposed to be unstable a postulation that contradicts observable evidence.

Bohr's model of the atom consists of atoms, having electrons in specific orbits. The theory explains spectroscopy and enabled the determination of the constituent atoms present in distant stars.
