Explanation:
Ms. Hendren has decided that she would like to grow some tomatoes and wants to know how much light will cause the plant to grow the largest tomatoes. She plants tomato seeds in 4 different pots and leaves one pot in the dark. She gives 6 hours of light a day to the second, 8 hours of light a day to the third, and 10 hours of light a day to the fourth. After 3 months she measures the size of the tomatoes grown. Match up each variable in the experiment. Group of answer choices Independent varible [ Choose ] Dependent variable [ Choose ] Control variable [ Choose ] Control group [ Choose ]
Answer:
The correct answer is -
Independent variable - the amount (time period) of light given to pots.
Dependent variable - size of tomatoes
Control variable - dark or absence of light
Control group - pot placed in the darkroom.
Explanation:
The independent variable is the variable that is changed or manipulated in particular research or study to see the effect of that variable on dependent variable. In this case, the amount of light each pot gets is the independent variable.
The dependent variable is the variable that depends on the change in the independent variable. The size of tomatoes is the dependent variable here.
The control variable is the variable that remains in standard condition or condition which can be used to compare with the effect of the independent variable. The absence of light on one of the tomato pot is the control variable.
The control group is the group of subjects did not get any treatment that experiment group receives. The pot which is placed in the dark room is control group here.

All eukaryotic cells contain mitochondria. What does this mean?
Answer:
Mitochondria- often called the powerhouses of the cell — enable eukaryotes to make more efficient use of food sources than their prokaryotic counterparts. That's because these organelles greatly expand the amount of membrane used for energy-generating electron transport chains.

The Titanic was said to be “unsinkable”. What happened April 15, 1912 that caused it to sink?
Answer:
After the water gushed aboard and the boat split into two, there was nothing left that kept the boat afloat. The weight of water and gravity ultimately pulled the large cruiser to its watery doom.
Explanation:
I HOPE THIS HELPS
Answer:
Explanation: The immediate cause of RMS Titanic's demise was a collision with an iceberg that caused the ocean liner to sink on April 14–15, 1912. While the ship could reportedly stay afloat if as many as 4 of its 16 compartments were breached, the impact had affected at least 5 compartments.

Lion vs elephant digestion lab
Answer:
In lions, digestion takes place in the stomach while in elephant, digestion takes place in cecum.
Explanation:
Lion eats meat which needs a powerful digestion of strong juices which helps in the breakdown of food. There are four compartments of the stomach of lion that are rumen, reticulum, omasum, and abomasum. These chambers have microorganisms which helps in the breakdown of food materials while in the elephant, the stomach primarily functions in the storage of food and digestion takes place in the cecum that is connected to the large intestine.

nitrogen fixation
a) is the process where nitrogen is converted to a usable form
b) is accomplished by plants when they break down soil.
c) occurs as a result of photosynthesis
d) none of the above
Answer:
A. is the process where nitrogen is converted to a usable form
Explanation:
Fixation converts nitrogen in the atmosphere into forms that plants can absorb through their root systems. A small amount of nitrogen can be fixed when lightning provides the energy needed for N2 to react with oxygen, producing nitrogen oxide, NO, and nitrogen dioxide, NO2

What is the role of light and chlorophyll in photosynthesis?
Explanation:
During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.
In photosynthesis, role of light is to convert water and carbon dioxide to organic products and chlorophyll helps in absorbing light energy from the sun.
What is photosynthesis?It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

How did Claire’s digestion reaction rates tell you that the problem was in her small intestine, and not her stomach?
Absorption of the nutrients will not happen in her small intestine.
Claire’s digestion reaction rates tell you that the problem was in her small intestine, and not her stomach because the intestine is responsible for the absorption of most of the nutrients produced from eating and drinking of food substances.
If the absorption of the nutrients will not happen by the intestine, the whole homeostasis or equilibrium of the body disturbs and no growth of the cell occurs so we can conclude that absorption of the nutrients will not happen in her small intestine.
