If an animal fossil was found in a rock, what would be the best way to determine its absolute age?

Biology

LiRa [457]3 years ago

Answer:

D

Explanation:

Absolute age is defined as the numeric age of fossils.

To identify the absolute age of a fossil,  the amount of certain radioactive elements in the rock are measured. When fossils are formed in the rocks, a small amounts of radioactive elements is included in it. The process to identify age of fossil using radioactive elements is known radiometric dating. So, radioactive isotope and its decay product gives absolute age of fossils.

Hence, the correct answer is "D".

Find the hypotenuse of a right triangle whose legs both have a length of 5.
natali 33 [55]

Answer:

Hypotenuse = 7.07 units.

Explanation:

The sides of the right angle triangle are the opposite and adjacent side; which are both equal in this case.

Given the following data;

Opposite = 5 units

Adjacent = 5 units

To find the hypotenuse, we would use the Pythagorean theorem given by the formula;

Hypotenuse² = opposite² + adjacent²

Hypotenuse² = 5² + 5²

Hypotenuse² = 25 + 25

Hypotenuse² = 50

Hypotenuse = √50

Taking the square root of both sides, we have;

Hypotenuse = 7.07 units.

What happens when a resting neuron's membrane depolarizes? A. There is a net diffusion of Na⁺ out of the cell. B. The equilibriu
m_a_m_a [10]

The correct option is (C) The neuron’s membrane voltage becomes more positive.

The resting neuron has a voltage across its membrane which is called the resting membrane potential. There is a concentration gradient of ions across the membrane when the neuron is in the resting state.

Inside the membrane the concentration of  K⁺ and organic anions are more. Outside the membrane the concentration of Na⁺ is more. The membrane is much more permeable to K⁺  than Na⁺ .

The cell’s inside is more negative than the outside when the membrane is hyperpolarized. In neurons the resting membrane potential is close to the equilibrium potential for K⁺.
