Controlled variable - the variable that is kept the same during a scientific experiment.
We want to investigate the correlation between the light intensity and the rate of photosynthesis.
We can adjust the amount of light intensity by moving the lamp near or far from the aquatic plant.
We can also measure the amount of gas produced by photosynthesis in one minute.
(1) What is the independent variable in this experiment?
(2) What is the dependent variable in this experiment?
(3) What are the controlled variables in this experiment?
(4) What will be observed if the photosynthesis is happening more slowly?
I (5) What can you conclude from this experiment?

Answers

Answer 1

1. Independent variable = light intensity

2. Dependent variable = rate of photosynthesis

3. Controlled variables a= other variables - independent and dependent

4. Low amount of gas will be produced

5. Light intensity has a correlation with the rate of photosynthesis

Experimental variables in photosynthesis

During photosynthesis, carbon dioxide and water combine to form carbohydrates in the presence of solar radiation. The process in specific to green plants only and oxygen is evolved as a by-product. The higher the amount of oxygen produced, the higher the rate of photosynthesis.

Independent variables in experiments are the variables supplied directly by the experimenter which can be manipulated to see if it produces any effect or outcome.

The dependent variables are variables that measure the effect of the independent variable.

The remaining variables apart from dependent and independent variables are controlled variables.

From the experiment investigating the effects of light intensity on the rate of photosynthesis, all other things being constant, the more the light intensity, the more the rate of photosynthesis.

What cell parts are common to all of these cells?
Use complete sentences.

Chlamydomonas
Spirogyra
Elodea
Squamous Epithelium

Answers

Answer: All cells share four common components: (1) a plasma membrane, an outer covering that separates the cell's interior from its surrounding environment; (2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; (3) DNA, the genetic material of the cell; and (4). The cells of most Chlamydomonas species are more or less oval and feature a noncellulosic membrane (theca), a stigma (eyespot), and a usually cup-shaped chloroplast. Although photosynthesis occurs, nutrients also may be absorbed through the cell surface. Asexual reproduction is by zoospores. The filamentous masses come to the surface and become visible as slimy green mats. Spirogyra has a cell wall, nucleus, pyrenoid and spiral chloroplasts. This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis). The central vacuole takes up most of the volume of the cell. Squamous cells tend to have horizontally flattened, nearly oval-shaped nuclei because of the thin, flattened form of the cell. Squamous epithelium is found lining surfaces such as skin or alveoli in the lung, enabling simple passive diffusion as also found in the alveolar epithelium in the lungs. brainliest?

Explanation:

An acid-fast staining method was performed on a bacterial smear using the dyes carbol fuchsin and methylene blue. The resulting stained slide contained only cells that appeared blue when visualized using a microscope. Which of the following could explain why only blue cells were present?

a. No acid-fast bacteria are present on the slide
b. Methylene blue was not used
c. Carbolfuchsin was not used
d. Acid-alcohol was not used

Answers

Answer: Only blue cells where present because No acid-fast bacteria are present on the slide. The correct option is A.

Explanation:

Acid fast staining method also called Ziehl-Neelsen (Zn) technique is used in the laboratory to stain samples suspected to contain Mycobacterium species. The Mycobacterium species which includes the M. tuberculosis, M. ulcerans, and M. leprae, do not stain well by the Gram technique, which is a common routine stain in the laboratory. This is because of waxy coating on its cell surface primarily due to the presence of mycolic acid.

The acid fast stain consists of:

--> A primary dye which is the carbol

fuchsin

--> A decolorizer which is the acid alcohol

--> A counter stain which is the methylene blue.

In it mechanism of action on the bacterial smear, when the primary dye is applied,the whole cell will appear red. But after decolorizing with acid alcohol, only acid fast bacteria will retain the red colour of carbol

fuchsin while the red dye from the background cells are removed. Then the counterstain (methylene blue) is applied which is picked up by non-acid-fast bacteria making the cells appear blue under the microscope.

Therefore when the bacteria smear is viewed under the microscope and only blue cells are seen, it means No acid-fast bacteria are present on the slide.

Several inches of snow had fallen since the last sled had passed. He was glad he was without a sled. Actually, he carried nothing but the lunch wrapped in the handkerchief. He was surprised, however, at the cold. It certainly was cold, he decided, as he rubbed his nose and face with his mittened hand. He had a good growth of hair on his face, but that did not protect his nose or the upper part of his face from the frosty air. Following at the man's heels was a big native dog. It was a wolf dog, gray-coated and not noticeably different from its brother, the wild wolf. The animal was worried by the great cold. It knew that this was no time for traveling. Its own feeling was closer to the truth than the man's judgment. In reality, it was not merely colder than 50 below zero; it was colder than 60 below, than 70 below. It was 75 below zero. Because the freezing point is 32 above zero, it meant that there were 107 degrees of frost. The dog did not know anything about temperatures. Possibly in its brain there was no understanding of a condition of very cold, such as was in the man's brain. But the animal sensed the danger. Its fear made it question eagerly every movement of the man as if expecting him to go into camp or to seek shelter somewhere and build a fire. The dog had learned about fire, and it wanted fire. Otherwise, it would dig itself into the snow and find shelter from the cold air.How does the setting affect the character(s) and enhance the mood of the passage?
