Answer: The radioactive isotopes can be used to track many physiological functions and chemical reactions occurring within the cells of the living organisms including plants.
Explanation:
Phosphorus uptake by the plants: Phosphorus is an essential mineral required by the plants for their growth and metabolism. The radioactive phosphorus-32 can be used to track back the rate at which the plant absorbs the phosphorus from the soil. This can help scientists to identify plants that can absorb phosphorus more quickly.
Pesticides levels in the plants: The pesticides levels in the plants can be traced by using radioisotopes such as chlorine-36. This can be used to trace the fact that how much of pesticide is present in the soil and how much of it is utilized by the plants. This is helpful identifying the fact that which pesticide is useful for the growth of the plants.

How are photosynthesis and cellular respiration connected as a cycle?
Answer:
Photosynthesis is when energy, carbon dioxide and water react to produce glucose and oxygen. It is an endothermic reaction (takes in more energy than it gives off).
glucose + oxygen + (energy) → carbon dioxide + water
C 6 H 12 O 6 + 6 O 2 → 6 CO 2 + 6 H 2 O
Respiration is the process of producing energy from glucose. It uses glucose and oxygen to give water, carbon dioxide and energy (thus making it exothermic).
carbon dioxide + water + energy → glucose + oxygen
6 CO 2 + 6 H 2 O → C 6 H 12 O 6 + 6 O 2
As you can see from the equations, they are essentially the reverse of each other.
Another difference is how they are used. Respiration occurs in the mitochondria of all living cells, whereas only plants photosynthesize.
In plants, they make their own glucose using the sun's energy, then respire to allow them to use the glucose for the energy they can use. The glucose can also be stored and used in many other ways other than in respiration.
What is the relationship between photosynthesis and respiration?
A Photosynthesis produces water, while respiration does not. .
B. Respiration requires sunlight, while photosynthesis does not.
C. Photosynthesis produces oxygen, and oxygen is required for respiration
D. Respiration produces glucose, and glucose is required for photosynthesis iser
Answer:
c.
Explanation:
That be your answer mate.
Answer:
the correct answer is c
Explanation:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
Which of the following is not an example of coevolution? A. Prey evolve faster running to escape, and predators evolve to smarter at catching prey. B. Predators evolve heavy jaws to crunch the bones of herbivores, and herbivores evolve thick fur for warmth. C. Plants evolve chemical defenses and herbivores evolve ways to neutralize the chemicals. D. Insects evolve green wings to blend into the environment, and predators evolve better eyesight to find the prey. Explain why.
The statement 'predators evolve heavy jaws to crunch the bones of herbivores, and herbivores evolve thick fur for warmth' is NOT an example of coevolution.
Coevolution is an evolutionary process where two or more species evolve in a parallel manner.Coevolution is caused by an evolutionary race between species.In general, coevolution is caused by selective pressures between one taxonomic group on another.In conclusion, the statement 'predators evolve heavy jaws to crunch the bones of herbivores, and herbivores evolve thick fur for warmth' is NOT an example of coevolution.

Explain how colonial organisms may have evolved into eukaryotic cells.
Answer:
The hypothesis that eukaryotic cells evolved from a symbiotic association of prokaryotes—endosymbiosis—is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.

Fruit is a group of alkenes. (go to step 2) b. Fruit is a group of follicles. (go to step 4) #2. a. Petals are not present. (go to step 3) b. Petals are present. (Ranunculus) #3. a. The flower has 4 sepals. (Clematis) b. The flower has 5 sepals. (Anemone) #4. a. The flowers are regular. (Aquilegia) b. The flowers are irregular. (Delphinium) The flower is a: A. Anemone B. Clematis C. Delphinium D. Ranunculus
Question:
Use the following dichotomous key to identify an irregular blue flower with five petals and a fruit that is a ripened flower ovary or follicle.
Dichotomous Key of Ranunculaceae
#1.
a. Fruit is a group of alkenes.............................. go to step 2
b. Fruit is a group of follicles..............................go to step 4
#2.
a. Petals are not present.....................................go to step 3
b. Petals are present............................................Ranunculus
#3.
a. The flower has 4 sepals.................................. Clematis
b. The flower has 5 sepals................................... Anemone
#4.
a. The flowers are regular..................................... Aquilegia
b. The flowers are irregular................................... Delphinium
The flower is a: A. Anemone B. Clematis C. Delphinium D. Ranunculus
Answer:
The species belongs to Delphinium genera.
Explanation:
A dichotomous key is relatively simple to interpret. All you need to do is to:
- carefully observe your organism,
- know some technical terms or have a biological dictionary, and
- follow the descriptions.
The dichotomous key is going to lead you to the answer.
In the example, we have a plant species with irregular blue flowers and five petals. The fruits are a ripened flower ovary or follicles.
Irregular flower: Term that refers to asymmetrical flowers that only have one plane. Follicle: Term that refers to dry dehiscent fruits originated from a flower with only one carpel. When mature, they open by the ventral suture.So, let us begin, step by step. For each number, we are going to have two options (a and b). By knowing our organism, we need to decide which one is correct and follow indications.
#1.
a. Fruit is a group of alkenes.............................. go to step 2.
b. Fruit is a group of follicles..............................go to step 4.
We know that our fruit is a follicle. Option a is not correct (it is not a group of alkenes). Option b is the correct one. Knowing this, we must go to step four. ***Note: In the hypothetical case that the fruits were a group of alkenes, and option a was correct, we should go to step two, as indicated***.
#4.
a. The flowers are regular..................................... Aquilegia
b. The flowers are irregular................................... Delphinium
We know that our flower is an irregular one. So the correct option is b. This option leads us to Delphinium genera. Our species belongs to this taxonomic group. ***Note: In the hypothetical case that the fruit was actually a regular flower, and option a was correct, our species would belong to Aquilegia genera***

A group of students were interested in showing photosynthesis occurring visually. They decided to use bromothymol blue which is an indicator that turns green when there is a high concentration of carbon dioxide and blue when there is a low concentration of carbon dioxide in water. All the tubes started out blue, but students blew carbon dioxide into two of the test tubes turning them green. They left one test tube of each color as their control and put a piece of aquatic plant in the other two tubes. Then, they put all four of these tubes outside (Monday 7 am). When the students checked their tubes in the afternoon (Monday 1 pm), they were so excited to see that tube D had turned blue! Carbon dioxide was going away and being replaced with oxygen. When the students checked their experiment early the next morning, tube B and D had both turned green! Did photosynthesis occur during the experiment? Support your claim with evidence explain your reasoning.
Answer:
photosynthesis did not occur.. because if photosynthesis had occured oxygen would be produced..but the tubes turned green proving there was more carbondioxide than oxygen Which proves photosynthesis didn't take place.

As the test tube turned green, it means that photosynthesis did not occur in the test tubes.
What is bromothymol blue?Bromothymol blue (BMB) is a dye that turns yellow when exposed to acid. When carbon dioxide is added to a solution, it produces carbonic acid, which lowers the pH.
When the pH is greater than 7.6, BMB is blue, green when the pH is between 6-7.6, and yellow when the pH is less than 6.
Carbon dioxide dissipates in water to produce a weak acid. As a result, an acid-base indicator like bromothymol blue (BTB) can be used to detect the presence of CO2.
The person basically use bromothymol blue as an indicator to determine how much CO2 remains in test tubes containing light-exposed plants.
Thus, as there were some drawbacks in the experiment, the test tube B and D got green color, which means the level of carbon dioxide were more. This implies, photosynthesis did not occur.
