Answer:

d. The dependent variable is the vitamin C levels in the pineapples and oranges.

Explanation:

<em>Select all the statements that are true about this experiment.</em>

a. The independent variable is temperature. NO, temperature, as well as rain and sunlight are controlled variables and are not being evaluated in the experiment.

b. the control group in the experiment is the oranges. NO, there is no control group in this particular experiment.

c. The type of fruit is a controlled variable. NO, the type of fruit is the independent variable.

d. The dependent variable is the vitamin C levels in the pineapples and oranges. YES. According to your hypothesis, the vitamin C levels depend on the type of fruit.

Feliz [49]

Answer:

-During citric acid cycle or Krebs cycle, radioactive carbon will be first appear in citric acid

Explanation:

During cellular respiration, glucose is first converted into pyruvate molecules by the process of glycolysis. These pyruvate molecules go for oxidative decarboxylation, during which acetyl co-enzyme A (acetyl CoA) is formed along with removal of carbon dioxide.

The acetyl co-enzyme enters to the next step in cellular respiration or citric acid cycle or Krebs cycle. The first step of citric acid cycle is formation of citric acid by joining of acetyl CoA and oxaloacetate.

As citric acid is first molecule formed during citric acid cycle, radioactive carbon would be first appear in citric acid.

Describe how iron turns into a brownish-red powder. Name the reactants and products that are involved.
Naily [24]

The brownish-red powder on iron is called rust. It is formed by the reaction of iron and oxygen in the presence of water or air moisture. It is called oxidizing or rusting due to exposure to water and air.

The reactants are oxygen and iron the products are carbon dioxide and water and the process is oxidization.

After the completion of meiosis in humans, a diploid germ cell has produced cells with half the original chromosome number, gene
Andreas93 [3]

Answer: 23

Explanation:

After the completion of meiosis in humans, a diploid germ cell has produced cells with half the original chromosome number, generating 23 haploid nuclei.

Meiosis is cell division that reduces chromosome number by half. Hence, a diploid germ cell with 46 chromosomes (23 pairs) is halved to 23 nuclei at the end of meiosis, the 23 nuclei will be carried by the sex gamete

In the lab, you isolate a chlorella mutant that is unable to switch xanthophyll pigments into the inactive, non-heat-dissipating
REY [17]

Answer:

No, because xanthophyll dissipates absorbed light as heat, and in low light environments, such dissipation would decrease photosynthesis and therefore growth.

Explanation:

Xanthophyll is one of the accessory pigments present in organisms. Being an accessory pigment, the function of xanthophyll is to dissipate the absorbed visible light. Since it dissipates the visible light, the light cannot be used by Chlorella to drive the light-dependent reactions of photosynthesis.

When a mutant Chlorella is grown in the shady region, the dissipation of light by xanthophyll would further reduce the rate of photosynthesis. This mutation is not an adaptive feature in shady regions where the rate of photosynthesis is already lower due to limited availability of light and therefore, would not be favored by natural selection and would not spread to the future generations.
