What is the connection between adaptation and fitness

kenny6666 [7]

Answer:

Adaptations increase fitness.

Explanation:

Animals with the most fitness are most likely to survive. In a given population, there are small mutations that accumulate over time. If these mutations are useful in increasing fitness, they become adaptations that help increase fitness.

Calculate the number of moles of Cu in 3.8×10213.8×1021 atoms of Cu.

rosijanka [135]

Answer:

6.3×10⁻³ moles of Cu

Explanation:

The relation is, that 1 mol of particles are contained by 6.02×10²³ particles.

This is Avogadro's number that explains that: one mole determines the number of fundamental units that are contained in a constant number but they do not depend on the type of material or the type of particle, and this quantity is 6.02 × 10²³

We can make a rule of three:

6.02×10²³ atoms are contained 1 in mol of Cu

Therefore, 3.8×10²¹ atoms will be contained in (3.8×10²¹ . 1) / NA = 6.3×10⁻³ moles

How many protons, electrons, and neutrons does an atom with atomic number 50 and a mass number of 125 contain?

EleoNora [17]

Answer:

a) 50 protons, 50 electrons, 75 neutrons

Explanation:

How many protons, electrons, and neutrons does an atom with atomic number 50 and a mass number of 125 contain?

a) 50 protons, 50 electrons, 75 trons

b) 75 electrons, 50 protons, 50 neutrons

c) 120 neutrons, 50 protons, 75 electrons

atomic number IS the number of protons

atomic mass IS the total of protons + neutrons

so 50 protons

125-50 = 75 neutrons

in a neutral atom,

number of negative electrons = number of positive protons

a) 50 protons, 50 electrons, 75 neutrons
