Describe a control for the above experiment. The factor, the presence of starch (if the process of photosynthesis has taken place or not) needs to be left out. How would you do this?​

Answers

Hi their here is the Answer

During photosynthesis a plant absorbs light energy using the pigment chlorophyll. This allows it to convert carbon dioxide and water into glucose. This glucose is:

transported to the growing parts of the plant for use in respiration
transformed into cellulose, proteins and oils
turned into starch for storage
Therefore, to test if a plant has been photosynthesising, you can test the leaf to see if starch is present.

Iodine solution is used to test leaves for the presence of starch. You need to:

heat a plant leaf in boiling water for 30 seconds (this kills the leaf, stopping any chemical reactions)
add the leaf to boiling ethanol in a water bath for a few minutes (the boiling ethanol dissolves the chlorophyll and removes the green colour from the leaf - it turns white so it is easy to see the change in colour)

wash with water to rehydrate and soften the leaf and spread onto a white tile
add iodine solution from a dropping pipette
After a few minutes, the parts of the leaf that contain starch turn the iodine from brown to blue/black.

Hope this helps :)

What are the products of cellular respiration?
A. Energy, carbon dioxide, and water
B. Oxygen, carbon dioxide, and water
C. NADPH and oxygen
D. Glucose and ATP

Answers

Answer:

A

Explanation:

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.

So the answer is A. Energy, carbon dioxide, and water

4. Assertion A: Prokaryotes are identified by the membrane bound cell organelles. Reason R: Prokaryotes are considered as the primitive forms of life. *
a) Both A and R are true and R is the correct explanation of A.
b) Both A and R are true but R is not the correct explanation of A.
c) A is true but R is false.
d) A is false but R is true.

Answers

Answer:

d) A is false but R is true.

Explanation:

Prokaryotes are group of organisms that do not possess a membrane bound nucleus or any other membrane bound organelle in their cell e.g. mitochondria, endoplasmic reticulum etc. They lack such organelles.

However, they are truly considered as a primitive life form; much more primitive than eukaryotic organisms. Examples of prokaryotes are bacteria, archeae etc. Based on the above explanation, it is clear that the assertion (A) in this question is FALSE but the reason (R) is TRUE.

Think about how diet and weight-loss companies advertise. How do they use bias to sell their products?

Answers

Answer:

Companies that advertise diet and weight-loss products are well-known for using false or biased advertising. These companies are biased in the sense that they present images of beauty that are subjective as if they were objectively admirable. Moreover, they can play on people's insecurities due to a bias of what a person should ideally be like. It is very important, when dealing with these type of companies, to use skepticism when examining their data. It is very likely that the data has been modified in order to provide a very positive view of the effectiveness of their products. Moreover, it is important to look at their health claims, and not just at their weight-loss claims.

To be perfectly honest, I'm not sure what problem 32 is asking. It seems like there's set up to a question, but the actual question itself is missing.

=============================================

For problem 33, we divide the tape's distance by its time. I'm assuming that problem 33 is using the set up info from problem 32.

Recall that

distance = rate*time

we can rearrange things to say

rate = distance/time

So that's why we divide distance over time. The tape's length is effectively the distance, more or less. Imagine that one marker on the tape travels from one end of the reel to the other. It would have to travel the length of the tape when the full tape duration elapses.

----------

So,

rate = distance/time

rate = (260 meters)/(180 seconds)

rate = (260/180) meters per second

rate = 1.44 meters per second, which is approximate

I'm rounding to 3 sig figs.

A student wants to perform an experiment to test the effect of different colored lights on the growth of basil plants. She sets up an experiment where multiple basil plants are placed in six different setups; one with red light, one with green light, one with yellow light, one with blue light, one with no light and one with sunlight. In each setup the plant receives the same amount of water, soil, and size of container. What is the independent variable in this experiment

Answers

Answer:

light is the independent variable, height of the plant is the dependent variable. Dependent is the effect that based on the independent.

Explanation:

lets break it down. 1) you want to know the effect of something you apply from one thing to another. Let say, if you grow your plants under the sunlight, the plants grow taller. In this case, the sunshine is the independent variable whereas the height of the plant/how tall it can grow is the dependent variable. 2)NOW, before i give the answer. The design of the question is not good for high school students. i think your teacher thinks "light" is the independent variable. 3)However, the question contains confounding variables in it because different lights might produce different effects to the height of the plants. If you want to test if plants are exposed to light grows taller than plants do not expose to light, then you should have all the lights are the same. 4) So, all the plants should be exposed to one certain light to avoid confounding. Confounding means that either red light and sunlight are both produce the same effect whereas the other colors do not help the plants to grow taller. 5)Your teacher should test one light at a time. So, if he is testing with all different colors of light, then light is the independent variable, and height of the plant is the dependent variable.
