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
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 3 major organs of excretion and what do they excrete?
Answers
Answer:
Skin, Kidneys, And Lungs
Explanation:
Excretion is the removal of toxic materials, waste products of metabolism and excess substances from organisms. Egestion is the passing out of undigested food as faeces, through the anus. Three major organs of excretion are the skin, kidneys and lungs. Sweat glands in the skin produce sweat.
A sponge actually feeds by
a. acting as a net in a current that sweeps food particles through it.
b. squeezing the spongocoel cavity and sucking debris in and out through the osculum.
c. the beating of the flagella of collar cells, forming a current; food is absorbed by collar cells.
d. the beating collar cells form a current from osculum to pores; the food is engulfed by amoebocytes in the central cavity of the sponge.
e. water the moves gently through the sponge and the amoebocytes that engulf passing food.
Answers
Answer:
c. the beating of the flagella of collar cells, forming a current; food is absorbed by collar cells.
Explanation:
Sponges contains the unique feeding system that should be with the animals. Rather of mouths they have the tiny pores that we called as the ostia displayed on the outer walls via water is drawn. Here cells in the sponge walls strainer the food from the water because the water is pumped via the body and the little mouth
So as per the given options, the option c is correct as the collar cells would create the current and the food should be absorbed by the collar cells

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.
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.
Mechanical weathering is more rapid in warm, wet climates.
true or false?
Answers
Answer:
false
Explanation:
In cold climates, water freezes and expands as a result, breaking rocks with sheer force. The smaller rocks or sediments are washed away by erosion.
During the warm wet season, rocks expand and contract. As a result, the rocks are weakened and eventually fracture.
Note that the rate of weathering depends on the types of rock and temperature change. Rocks in tropical climates experience the highest rate of weathering because of the combination of high heat and heavy rainfall.

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.

This sea anemone and this ctenophora both have tentacles, which are body structures that help them catch food. However, sea anemone tentacles are short and can sting, while ctenophore tentacles are long for grabbing and cannot sting. What most likely explains why both species have tentacles and why the tentacles are different
Answers
Answer: Sea anemone and ctenophore both inherited tentacles from a shared ancestor population, but this population separated into different environments. In each environment, different types of tentacles evolved, which helped the populations survive.
Explanation:
most likely explains why both species have tentacles and why the tentacles are different is because sea anemone and ctenophore both inherited tentacles from a shared ancestor,
Then, this population separated into different environments and there was tye evolvement of different types of tentacles evolved, which therefore helped the populations survive.
