A block is pulled 0.90 m to the right in 2.5 s.
Blizzard [7]

The block’s average speed : 0.36 m/s

<h3>Further explanation</h3>

Distance is the length traveled by an object within a certain of time .  

Average speed = total distance/total amount of time ,

Can be formulated :

\tt avg.s(speed)=\dfrac{\Delta D}{\Delta t}

ΔD= total distance

Δt= total time

A block is pulled 0.90 m to the right in 2.5 s :

ΔD= total distance = 0.9 m

Δt= total time = 2.5 s

The block’s average speed :

\tt avg.s=\dfrac{0.9}{2.5}=0.36~m/s

Explain in your own words the process using the following key words: carbon-di-oxide, water, sugar, oxygen, thylakoid, chloropla
AleksAgata [21]

Answer:

The Photosynthesis process

Explanation:

Plants, algae, and some other organisms can transform the sunlight energy into chemical energy. The photosynthesis process occur thanks to the chloroplasts. The chloroplast is an organelle found in all green plants. Inside of the chloroplast you can find the thylakoids which are arranged in stacks named grana, they have membranes with chloropyll a photosynthetic pigment, also you can find the photosystems, they are functional and structural units of protein complexes. The thylakoids capture the light and allow the reactions to transform CO2. The set of reactions that occurs in the chloroplasts are known as the Calvin cycle.

The general equation of photosynthesis is:

6 CO_{2}                 + 6 H_{2} O + Energy  -> C_{6} H_{12} 12O_{6}  +  6 O_{2}

6 CO2                + 6 H2O + Energy  -> C6H12O6         +  6 O2  

Carbon Dioxide  + water  +  Light   -> Glucose (sugar) + Oxygen

After, this glucose is transformed into pyruvate, and it allowed the release of denosine triphosphate (ATP) by cellular respiration. The ATP is an organic chemical that is requires for the cell to perform any process (any kind or work).
