Answer:

Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxygen is also formed.

Answer:

During photosynthesis,

#Plants absorb light energy from the sun in the presence of chlorophyll.

#Convertion of light energy into chemical energy and splitting of water molecules into hydrogen and oxygen.

#Reduction of carbon dioxide into carbohydrates

Explanation:

-There are two steps in photosynthesis. The first step directly utilizes light energy and occurs in the thylakoids of chloroplasts. It is called light reaction or photochemical reaction. The second step utilizes assimilatory power of light reaction and occurs in the stroma of chloroplasts. It is called dark reaction or thermochemical reaction

what two errors in the data will result if you raise the temperature of the melting point apparatus too quickly?

grandymaker [24]

The two errors in the data resulting from an experiment where the temperature is raised too quickly are: First, the melting point temperature may not be recorded correctly since it cannot be monitored closely if the heat supplied is too high. <span />

A helium filled weather balloon has a volume of 806 L at 20.9°C and 753 mmHg. it is released and rises to an altitude of 6.8 km,

OLEGan [10]

<h3>Answer:</h3>

1257.45 L

<h3>Explanation:</h3>

We are given;

Initial volume of Helium gas, V1 as 806 L
Initial temperature of Helium gas,T1 as 20.9°C
Initial pressure of Helium gas, P1 as 753 mmHg
Pressure of Helium at the altitude 6.8 km, P2 as 417 mmHg
Temperature of Helium gas at the altitude 6.8 Km, T2 as -19.1°C

But, K = °C + 273.15

Therefore, T1 = 294.05 K and T2 = 254.05 K

We are required to calculate the new volume of the balloon at 6.8 km.
To determine the new volume we are going to use the combined gas law.
According to the combined gas law, $\frac{P1V1}{T1}=\frac{P2V2}{T2}$

Thus, rearranging the formula;

$V2=\frac{P1V1T2}{P2T1}$

$V2=\frac{(753)(806L)(254.05K)}{(417)(294.05)}$

$V2=1257.45L$

Therefore, the volume of the balloon at an altitude of 6.8 km is 1257.45 L

Which of the following has the smallest radius Rb+, K, K+, or Rb+

Stells [14]

The trend of elemental radius increases from top to bottom and from right to left. This means Rb is greater than K. Incorporating the positive charges, K+ is smaller than K and Rb+ is smaller than Rb. Thus, the trend in increasing order is K+,K,Rb+,Rb.

As a system becomes less random, its entropy *<br><br> decreases<br> remains the same<br> increases

Yakvenalex [24]

Answer:

decreases

Explanation:

The higher the entropy, the more unpredictable and the more random a value is, this is because entropy describes disorder of a system. If things are less random, that means they are predictable, which means they are more ordered.
