2. photosystem II
3. photosystem I
C. 1. photosystem I
2. photosystem I
3. photosystem II

2. photosystem II
3. photosystem II

Answers

Answer 1
Answer:

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

B.

1. photosystem II

2. photosystem II

3. photosystem I

Answer 2
Answer:

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.

Two objects attract each other with a gravitational force of 25 newtons from a given distance. If the distance between the two objects is reduced by a factor of 5, what is the changed force of attraction between them?

Answers

Answer:

  • The changed force of attraction between the two objects is 625 N.

Explanation:

The universal law of attraction states that the gravitational attraction between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

The mathematical expression is:

  • F = G m₁ m₂ / d², where

  • G is the gravitational constant,
  • m₁ and m₂ are the respctive masses of the two objects, and
  • d = distance between the two objects.

Then, if the masses m₁ and m₂ remain unchanged and the distance (on the denominator) is reduced by a factor of 5, the 1/d² = 1/(1/5)² = 5² = 25, which means that the force will be multiplied by 25.

So, 25 N × 25 = 625 N which is the changed force of attraction between them.

What is the order of steps through which a particle of gaseous water would travel as it made one complete trip through the water cycle

Answers

The order of steps through which a particle of gaseous water would travel as it made one complete trip through the water cycle are Evaporation, Condensation, Precipitation, Runoff, Infiltration, and Transpiration.

What are the sequential stages of the water cycle?

Water cycle refers to the continuous process of water movement on Earth involving evaporation, condensation, precipitation, and more. The water cycle, also known as the hydrologic cycle, consists of several interconnected stages.

It begins with evaporation, where water from bodies of water and the Earth's surface turns into water vapor due to heat from the sun. This vapor then undergoes condensation, forming clouds.

Precipitation occurs when condensed water droplets combine and fall as rain, snow, sleet, or hail. Surface runoff carries excess water to larger bodies, while infiltration sees water seep into the ground. Transpiration involves plants releasing water vapor into the atmosphere. These processes together complete the cycle.

How do scientist classify climates

Answers

Answer:

I think its according to what biome category each place is.  

Explanation:

Other influences are the weather patterns for example how much rainfall does a biome have in a year usually.

Environmental factors such as how much vegetation an area has can influence the growth of plants because they are used to a certain temperature or amount of rainfall which tells scientists if the area has a warm or cold climate.

What are the four characteristics of a mineral?

Answers

The characteristics of a mineral are:

1- Solid and Formed by inorganic processes

2- Naturally occurring , Definite chemical composition , Definite crystalline structure. If a rock has at least three of these characteristics then it is a mineral because some of these minerals don’t have the exact same characteristics.

3- A solid has to have a definite volume or shape although, all rocks have a solid shape. In rocks and minerals, particles are packed tightly. Unlike a liquid, a solid object does not flow to take on the shape of its container, nor does it expand to fill the entire volume available to it like a gas does.

4- For a rock to be a mineral, it must form from non-living materials. The rock cannot come from something that is, or was living.

5- Naturally occurring minerals were not formed from factories or anything.

6- When a mineral is made of the same material throughout. Basically, made of the same thing, like lava or ice or one item. This mineral has one of these three materials in rocks.

7-Has crystals inside or outside. One example is a geode that has crystals inside.

8- IT also characteristic with its Texture ,Hardness ,Luster or shine and Color or streak.

Final answer:

The four characteristics of a mineral are: naturally occurring, inorganic, crystalline structure, and definite chemical composition.

Explanation:

The four characteristics of a mineral are:

  1. Naturally occuring: Minerals are formed in nature and not by humans.
  2. Inorganic: Minerals are not made up of living organisms or their byproducts.
  3. Crystalline structure: Minerals have an ordered arrangement of atoms.
  4. Definite chemical composition: Minerals are composed of specific elements in fixed ratios.
