A. 1. photosystem II
2. photosystem III
3. photosystem I
B. 1. photosystem II
2. photosystem II
3. photosystem I
C. 1. photosystem I
2. photosystem I

Answers

There are different photo systems involved in the phenomenon of photosynthesis which are units of protein

The two photo-systems are required for aerobic photosynthesis

Photosystem I

Photosystem II

The photosystem II absorbs energy [ thus light energy excites electron]

In photosystem II splits water molecules are split.

The excited electrons are transferred through cytochrome to photosystem I

In photosystem I NaDPH is formed.

thus answer is

1. photosystem II

2. photosystem II

3. photosystem I

The correct locations for each of the events in photosynthesis are:

A. 1. photosystem II

2. photosystem III

What is photosynthesis?

Photosynthesis is the biological process by which green plants, algae, and certain bacteria convert light energy from the sun into chemical energy in the form of glucose (a type of sugar) and oxygen.

Photosynthesis is a fundamental process that sustains life on Earth and enables the existence of complex ecosystems and diverse organisms. It is the basis for the production of food, fuel, and other essential resources for both humans and the natural world.

Can someone explain #3

Answers

Answer:

Explanation:

Hey,

so here the student is saying that the given mass is of one atom. But when we usually talk about amu it is the unified atomic mass so mass of all the atoms present.

So that's why he is wrong.

Also the definitions states,

The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.

Answer:

See below.

Explanation:

121.76 amu is the Relative Atomic Mass of Antimony (the average mass of the different isotopes). . The element exists as a mixture of isotopes , the main one being SB121 which has a mass of 121.

The reaction between zinc and hydrogen chloride produces zinc chloride, hydrogen gas, and heat. If more heat is removed from the reaction, how does the rate of reaction change to counter the action?

Answers

Answer:

The rate of reaction increases to counter the action of removing heat.

Explanation:

The reaction between zinc and hydrogen chloride produces zinc chloride, hydrogen gas, and heat.
The reaction is exothermic reaction. Heat is produced in the reaction.
It means the temperature of system increase when reaction proceeds. When heat is removed from system, it stimulates the reaction to fast to produce more heat.
Due to fast reaction rate of reaction increases.

What is the correct formula for iron(III) oxide?

Answers

Answer:Fe2O3

Explanation:

the roman numeral tells you the charge of the metal, and you know oxygen is -2 charge so you need the least common multiple of +3 and -2 so that they cancel out, which is 6 so you need 2 of the +3 and 3 of the -2

Answer:

Fe 3+

Explanation:

iron is Fe and it's 3 and has positive

What causes sweating during running in order to maintain homeostasis

Answers

Homeostasis is defined as a constant, steady environment despite external changes, such as exercise. Exercise affects your body temperature, blood oxygen levels, sugar levels and hydration – all properties necessary for your survival. Your body uses an automatic feedback system to preserve normal temperature and water levels, so you can keep exercising. Eat properly and drink plenty of fluids to help your body maintain homeostasis. You need to drink and eat properly.

What is the percentage error if the experimental
value is equal to the accepted value?

Answers

If the experimental value is equal to the accepted value, the percent error is equal to 0. As the accuracy of a measurement decreases, the percent error of the measurement rises.
