what is the function of photosystems
Answer:
Photosystems are the functional units for photosynthesis, defined by a particular pigment organization and association patterns, whose work is the absorption and transfer of light energy, which implies transfer of electrons. Physically, photosystems are found in the thylakoid membranes.
Explanation:
The main functions of a photosystem are: they are a functional unit of photosynthesis, and they trap or release light.
What is a photosystem?Plants, algae, and cyanobacteria all have thylakoid membranes that contain photosystems. These membranes are found in the cytoplasmic membrane of photosynthetic bacteria as well as the chloroplasts of plants, algae, and other vascular organisms. The PSI and PSII subtypes of photosystems exist.
The functional components of photosynthesis are called photosystem, and they are identified by specific pigment organization and association patterns.
Therefore, the photosystem is responsible for absorbing and transferring light energy, which entails transferring electrons. The thylakoid membranes contain photosystem in terms of physical location.

this blood vessel?
lumen
magnification X8
3.1 x 10-2m
3.1 x 10-3 m
O 2.0 x 10-2 m
2.0 x 10-3 m
Answer:
B. 3.12 x [tex]10^{-3}[/tex] m
Explanation:
From the given picture, it can be deduced that;
the diameter of the image of lumen = 25.0 mm
= 25.0 ÷ 1000
= 0.025 m
And,
magnification = [tex]\frac{diameter of the image of lumen}{actual diameter of lumen}[/tex]
But magnification = 8,and diameter of the image of lumen = 0.025 m.
So that;
8 = [tex]\frac{0.025}{actual diameter of lumen}[/tex]
⇒ actual diameter of lumen = [tex]\frac{0.025}{8}[/tex]
= 0.003125
Actual diameter of lumen of the blood vessel is 3.12 x [tex]10^{-3}[/tex] m.

What is the role of photosynthesis and cellular respiration in the cycling of carbon; include the biosphere, atmosphere hydrosphere and geosphere?
Green plants use energy from the Sun to change carbon dioxide and water into food and oxygen. What clue tells you that this process is a chemical change?
Answer:
Chemical change is a change in which there is rearrangement of atoms and thus new substance is formed. There may or may not be a change in physical state.
Photosynthesis is a phenomenon in which green plants containing chlorophyll use sunlight as a source of energy to convert carbon dioxide and water to form glucose and oxygen. The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar and oxygen gas.

B. From the sun to the land
O O O O
C. From the land to the ocean
D. From the land to the sun
Answer:
From the ocean to the land. just took the quiz.
Explanation: a p e x
During the day, the air above land in coastal regions warms up more quickly and starts to rise, hence option A is correct.
What is the direction of the wind?As the warm air rises, a low-pressure region develops on the surface, enabling air from the sea to enter. As a result, the wind blows from the sea to the land during the day.
Predominant winds often blow east-west rather than north-south, especially in the afternoon when the land is being heated by the sun to its maximum.
the Coriolis effect causes wind systems to twist counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere most frequently in the spring and summer.
Therefore, because of the greater temperature differences between the ocean and nearby land, hence option A is correct.

Drop a paper a piece of thermocol and a piece of plastic from a height of 10 to 15 feet not the time for each object to hit the ground why does paper take more time than thermocol and thermocol more than the plastic piece make the paper to fell down in such a way that it should hit the ground before all of them and how does it happen
Answer:
The paper takes more time to fall than the piece of thermocol because it experiences a greater air resistance than the thermocol.
The thermocol takes more time than the piece of plastic because it experiences a greater air resistance.
The piece of paper can be made to fall faster than all of them and hit the ground faster by crumpling it and then giving it an initial velocity by throwing it downwards.
Explanation:
Objects falling freely due to the force of gravity alone are accelerated downwards at a constant value 9.8 m/s². This acceleration due to gravity is constant for all objects on the earth's surface and is independent of the mass of the objects.Therefore, when objects are release from the same height and allowed to fall freely under gravity, they are accelerated downwards to the same extent and are expected to hit the ground at the same time. However,due to the resistance of the air through which the objects are falling, they may hit the ground at different times depending on the shape of the falling objects.
Objects which have a greater surface area or volume per unit mass will experience a greater air drag or resistance and therefore, will take a longer time than objects of similar mass with a smaller volume or surface area.
The paper has a greater surface area per unit mass than the piece of thermocol, therefore, it takes more time to fall than the piece of thermocol because it experiences a greater air resistance than the thermocol.
The thermocol has a greater surface area per unit mass than the piece of plastic, therefore, it takes more time than the piece of plastic because it experiences a greater air resistance.
The piece of paper can be made to fall faster than all of them and hit the ground faster by crumpling it, thereby reducing its surface area per unit mass it and then giving it an initial velocity by throwing it downwards.
