Lines on a weather map connecting places of equal air pressure are called ________. question 26 options: isotherms isobars isopl

Inessa [10]

Isobars. Like for the barometro the term bar indicates the measurement of pression. Iso stays for "the same" (like isoscele=same sides)

NADH is also used by cells when making certain molecules. Based on your knowledge of the role of NADH in cellular respiration, w

chubhunter [2.5K]

Answer:

b. reducing molecules

Explanation:

Nicotinamide adenine dinucleotide (abbreviated NAD +, and also called diphosphopyridine nucleotide and Coenzyme I), is a coenzyme found in all living cells. The compound is a dinucleotide, as it consists of two nucleotides linked through their phosphate groups with a nucleotide that contains an adenosine ring and the other that contains nicotinamide.

In metabolism, NAD + participates in redox reactions (oxidoreduction), carrying electrons from one reaction to another.

Coenzyme, therefore, is found in two forms in cells: NAD + and NADH. NAD +, which is an oxidizing agent, accepts electrons from other molecules and becomes reduced, forming NADH, which can then be used as a reducing agent to donate electrons. These electron transfer reactions are the main function of NAD +. However, it is also used in other cellular processes, especially as a substrate for enzymes that add or remove chemical groups of proteins, in post-translational modifications. Due to the importance of these functions, the enzymes involved in the metabolism of NAD + are targets for drug discovery.

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

Consider a field plot containing 200 kg of plant material. Approximately how many kg of carnivore production can be supported? A

mixas84 [53]

Answer:

E) 2

Explanation:

The energy transfer through the food chain is not 100% from one consumer to another, or from the producer to the primary consumer, but instead it is around 10%. This means that if a producer has the 100% of energy, as it is the one that produces it, the primary consumer will only get 10% of its energy while consuming it, while the predator of the the primary consumer will only 10% from the primary consumer, or rather only 1% from the energy of the producer. In this case we have 200 kg of plant material. The plant material represents a producer, thus it is the one with 100% of energy. A herbivore will eat the plant material, getting 10% of its energy, thus this plant material is supporting about 20 kg of herbivore. The predator of the herbivore gets only 10% from the herbivore's energy, or only 1% of the producer's energy, thus only 2 kg of predator can be supported by the initial plant material.
