What conclusions can we draw from the lab about photosynthesis and cellular
GuDViN [60]

Answer:

Carbon dioxide and oxygen are recycled through photosynthesis and cellular

respiration forever unless something interrupts.

Explanation:

Photosynthesis and cellular respiration are two distinct and opposite metabolical processes undergone by living cells. They are opposite processes because one utilizes the products of the other as reactants.

Photosynthesis is a unique process to autotrophic organisms like plants. It is the process whereby plants synthesize their food in form of organic molecules (glucose) by combining Carbondioxide (CO2) and water (H2O) in the presence of sunlight.

The overall equation of photosynthesis is as follows:

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

On the other hand, cellular respiration is the process whereby living cells obtain energy (ATP) by breaking down food molecules (glucose) using oxygen to produce carbondioxide (CO2) and water as products. The overall equation is:

C6H12O6 + 602 -----> 6CO2 + 6H2O

Based on the lab experiments, it can be concluded that Carbon dioxide and oxygen are recycled through photosynthesis and cellular

respiration because photosynthesis recycles/reuses the products of cellular respiration, which are C02 and H2O while cellular respiration recycles/reuses the products of photosynthesis, which are C6H12O6 and O2. This process occurs naturally in the environment and will continue to do so unless something interupts.

Option B is incorrect because light energy from the sun powers photosynthesis while option C is incorrect because photosynthesis transforms light energy to chemical energy while cellular respiration transforms chemical energy to thermal energy.

3. What would happen if they crossed yellow jellyfish with coober Complete
lidiya [134]

Answer:

We know that the color of jellyfish is controlled by codominance inheritance pattern and yellow Y and blue B are two alleles and in case of heterozygous the goober or green color occurs then,

If Yellow jellyfish is crossed with goober, that is, YY X YB.

 the punnett square will be -

   Y      Y

Y   YY    YY

B  YB     YB

The possible genotype of offspring will be YY, and YB and therefore, the possible phenotype of offspring will be Yellow, and Green. The Percentage of yellow offspring will be 50% as two out of four are dominant for Y allele and two heterozygous conditions that is 50 % and as there are two copies B alleles are not present so zero percent of blue color.
