Cystic fibrosis (CF) affects both males and females and people from all racial and ethnic groups. However, the disease is most common among Caucasians of Northern European descent.

CF also is common among Latinos and American Indians, especially the Pueblo and Zuni. The disease is less common among African Americans and Asian Americans.

Misha Larkins [42]

Answer: A. is a measure of energy

Explanation:

Heat is one of the easiest forms of energy that man can detect in your environment because we have the sensation of cold, hot, sweat, drink liquids when we feel hot, see the engine of a car heat up, take a bath of water heated by an electric shower or a boiler, etc.

Heat transfer occurs until the moment bodies reach the same temperature (thermal equilibrium). Heat is the energy transferred between a system and its surroundings because of the differences in temperatures.

When a motor neuron and the skeletal muscle cell it innervates are at rest:?
Nuetrik [128]

<span>Particularly the skeletal muscles at rest gain most of their energy from the aerobic respiration of fatty acids. Hence fatty acids provide the majority of the energy for muscle metabolism when a person is exercising at 25% of VO2max. However, the motor neuron is at rest when a neuron is not receiving any input there will be a potential difference. Thus, the potential difference measured when the neuron is inactive and it is caled the resting membrane potential. </span>

A scientist is using a species of green algae to study the electron transport chain in photosynthesis. He uses a laser to inacti
jeka94

Answer:

D) In case 1, both PS I and PS II completely lose function; in case 2, a proton gradient is still produced.

Explanation:

The light dependent reaction of photosynthesis, which produces the ATP and NADPH needed in the light independent stage of the process, includes complexes of proteins and pigments called PHOTOSYSTEMS. These photosystems (I and II) are key to the functionality of the light dependent reactions in the thylakoid.

The major pigment present in both photosystems is CHLOROPHYLL A, which absorbs light energy and transfers electrons to the reaction center. Chlorophyll B is only an accessory pigment meaning it can be done without. Hence, if all of the chlorophyll A is inactivated in the algae but leaves chlorophyll B intact as in case 1, both PS I and PS II will lose their function because Chlorophyll A is the major pigment that absorbs light energy in both photosystems.

In case 2, if PS I is inhibited and PS II is unaffected, a PROTON GRADIENT WILL STILL BE PRODUCED because the splitting of water into protons (H+) and electrons (e-) occurs in PSII. Hence, H+ ions can still be pumped into the inner membrane of the thylakoid in order to build a proton gradient even without the occurrence of PS I.
