An experiment was designed to investigate the effect of caffeine on the heartbeat of Daphnia magna, or water fleas. These tiny, aquatic animals are used because their transparent bodies make it easy to see their hearts and measure their heart rates. Two populations of Daphnia were raised, (A) and (B). Both populations lived in tanks of water at the same temperature and received identical amounts of food. Every 2 hours, water fleas from both populations were selected and their heartbeats were monitored. Population (A) had 0.5 g of caffeine given to them five minutes before their heartbeat was checked. Population (B) were given 0.5 g of water and with no caffeine.
Answer:
This question is incomplete. It is asking to identify the following in the experiment:
Independent variable: CAFFEINE
Dependent variable: HEARTBEAT
Experimental group: POPULATION A, which were given 0.5g of caffeine
Control group: POPULATION B, which were not given caffeine
Constants: SAME TEMPERATURE, SAME AMOUNT OF FOOD, SAME TIME BEFORE CHECKING
Explanation:
Independent variable in an experiment is the variable which is changed or manipulated by the experiment. In this experiment, the independent variable is the CAFFEINE.
Dependent variable is the variable that is measured by the experiment or in other words, the variable that responds to changes made to the independent variable. In this experiment, the dependent variable is the HEARTBEAT measured.
The experimental group of an experiment is the group that receives the experimental treatment (caffeine). In this experiment, the POPULATION A of Daphnia magna, or water fleas are the experimental group because they received 0.5g of caffeine.
On the other hand, the control group is the group that does not receive the experimental treatment. In this experiment, POPULATION B did not receive any caffeine, hence, it is the CONTROL GROUP.
Constant or controlled variable are those variables that the experimenter must keep unchanged for all groups throughout the experiment, in order not to influence the experiment's outcome. In this experiment, the constants are: SAME TEMPERATURE, SAME AMOUNT OF FOOD, SAME TIME BEFORE CHECKING (2hrs)
define the following words a: biology
b:biotechnology
Answer:Biotechnology is a broad area of biology, involving the use of living systems and organisms to develop or make products. Depending on the tools and applications, it often overlaps with related scientific fields
biology the laws and phenomena relating to an organism or group
Biology: The study of living organisms is called biology
Biotechnology: Application of technologies in the field of biology.
What is the difference between biology and biotechnology?Biotechnology is a subfield of biology, which is a science. Biotechnology is the use of biology for human benefit, whereas biology is the study of living things. Biotechnology uses a variety of methods, such as the genetic engineering of bacteria, to produce industrial goods.
The anatomy of living things is what distinguishes biology from biotechnology. The anatomy and physiology of living things are the main topics of biology. Contrarily, biotechnology is concerned with technology. It has nothing to do with the least important aspects of a living thing's anatomy and physiology.
Hence, this is a detailed explanation of biology and biotechnology.

How are photosynthesis and cellular respiration related?
Answer:
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.
I hope that helps determine your answer.
The product of photosynthesis are the reactants of cellular respiration.
What is cellular respiration?Cellular respiration is the process by which cells convert the energy stored in food molecules into a form of energy that can be used by the cells.
This process takes place in the mitochondria of the cell and involves the oxidation of glucose (sugar) to produce ATP (adenosine triphosphate), which is the main energy source for cellular processes. Cellular respiration has several stages, including glycolysis, the citric acid cycle, and the electron transport chain, each of which contributes to the generation of ATP. The end product of cellular respiration is carbon dioxide and water.

They show us natural water features that we can use to find our way. Water features are in blue. Direction of stream travel can be determined by how the stream encounters the contour lines; the contour lines point upstream. In the example below, the stream runs from east (right) to west (left).

Which of the following is(are) non-technological ways of improving air quality?
a. using public transportation
b. building wind turbines
c. turning lights off when leaving a room
d. both a and c
Using public transportation and turning lights off when leaving a room are both non-technological ways of improving air quality. Therefore, (A) and (C) are correct.
What is air quality?An air quality index is a tool that is used by government agencies to communicate with the general public about the current level of air pollution as well as the level of air pollution that is expected to occur in the near future.
The Clean Air Act regulates a number of key air pollutants, including ground-level ozone, particle pollution, carbon monoxide, and sulfur dioxide. The AQI is determined based on these four pollutants. The Environmental Protection Agency (EPA) has developed national air quality standards to safeguard the general population from each of these contaminants.
We can improve the quality of the air by:

Which statement best describes the cell membrane of a living cell?
A) It is composed of proteins and carbohydrates
B) It has the same permeability to all substances found inside or outside the cell.
C) It is a double protein layer that doesn't allow things to pass through it.
D) It selectively regulates passage of materials into and out of the cell..
D) It selectively regulates passage of materials into and out of the cell.
The plasma membrane in a living plant cell is composed of a double lipid layer that gives it hydrophobic character and acts as a semi- permeable barrier. The partial permeability of the substances allows regulating the passage of substances from and to the interior of the cell. At the level of the plasma membrane there are several mechanisms and transport to allow the entry of substances needed for the cell or the output of synthesized products or metabolic waste, thus regulating the passage of substance in a selective way.They keep toxic substances out of the cell.They contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and metabolic products.Therefore, correct option is D)
