B. individual - a groundhog living in your backyard

C. ecosystem - all of the species of plants and animals and the non-living resources in a tropical forest

Explanation:

A community is defined as a group of populations of two or more different species which inhabit the same area at a certain time.

Individual is defined as one type of organism.

Ecosystem includes communities, the environment, the non-living or abiotic conditions and their influence on living organisms.

Common proteins are polymers of 20 different amino acids. How many amino acids are necessary for a protein polymer to have at le

VikaD [51]

Answer:

This way, for 20^2.55 = 2109 amino acids are require to have 2*1056 number different sequences.

Explanation:

Protein should contain 2*1056 of different sequence so

2*1056 = 20^x

Log (2*1056) = log 20^x

3.3246 = (x ) * 1.3010

X= 2.555

Calculate the mass defect for oxygen-16 given this data. Round to the 5es001-1.jpg decimal place. mass of an oxygen-16 atom: 15.

Naya [18.7K]

Answer:

Explanation:

Given parameters:

Mass of oxygen atom = 15.994914amu

Mass of a proton = 1.00728amu

Mass of a neutron = 1.00866amu

Unknown:

Mass defect = ?

From the periodic table, the number of the elementary particles in a neutral Oxygen atom is given below:

Number of protons = 8

Number of neutrons = 8

Number of electrons = 8

Solution

The mass defect examines the difference between the actual mass of an atom and sum of masses of the nucleons.

The mass of an atom is concentrated in the nucleus which contains protons and neutrons. Electrons have little to no weight compared with the nucleons.

To calculate the mass defect, we first know the mass of the nucleons first:

1 proton has a mass of 1.00728amu

8 protons will weigh: (8 x 1.00728)amu = 8.05824amu

For the neutrons:

1 neutron has a mass of 1.00866amu

8 neutrons will weigh: (8 x 1.00866)amu = 8.06928amu

Mass of the nucleons = mass of protons + mass of neutrons

= 8.05824amu + 8.06928amu

= 16.12752amu

The mass defect = mass of the nucleons - mass of the atom

= 16.12752amu - 15.994914amu

= 0.132606amu ≅ 0.13261amu to 5 decimal places
