A stapler is used to staple 100 papers; it jams 5 times during the trial. A different brand of stapler performs the same test; it jams 22 times.
1 OR 2 type of stapler 1. independent variable
1 OR 2 number of jams 2. dependent variable
Answer:
This question is asking to identify the independent and dependent variables in the experiment.
Independent variable: Type/brand of stapler
Dependent variable: Number of jams
Explanation:
The independent variable in an experiment is the variable that is subject to control or manipulation by the experimenter. It is manipulated in order to effect a change in the dependent variable, which is dependent on it. In this experiment, the INDEPENDENT variable is the BRAND/TYPE OF STAPLER USED because it is what is changed or manipulated to produce an outcome.
On the other hand, a dependent variable is that which the experimenter measures. It is the variable that responds to the changes made to the independent variable. In this experiment, the NUMBER OF JAMS is the variable responding to the type of stapler used (independent), hence, it is the DEPENDENT variable.

"Francesco Redi was a scientist that performed an experiment to determine whether maggots formed from rotting meat. Versions of his experiments are described below. Meat was placed in two beakers. One of the beakers was left open to the air. The other beaker was covered with a fabric that only allowed air to get in. As the meat rotted, flies landed on the meat in the open beaker but were unable to get to the meat with the fabric over it. After a few days, maggots appeared on the meat in the open beaker, but not in the closed beaker. In the next experiment, rotting meat was placed in two beakers. Dead flies were placed in one beaker, and live flies were placed in the other beaker. Both beakers were sealed, allowing no air in. Maggots appeared in the beaker with live flies, but not in the beaker with dead flies." 1. Explain how this experiment disproves the theory of spontaneous generation. (3 points)
Answer:
Francesco Redi performed an experiment explained in the question to confirm wheather maggots formed from roeeting meat. He explained that maggots on meat do not form spontaneously.
These maggots come from the eggs laid by flies on the meat as it is only found on open meat jar where flies can go and lay their eggs. It disaproves the spontaneous generation thoery as if it was true open jar or closed jar every rotting meat jar must carry maggots on them.

imagine a bodybuilder flexing their muscles. which type(s) of tissue go into that action?
Answer:
The tissues that come into action are cartilaginous, bone, muscular and tendon.
Explanation:
It must also be taken into account that the joints are the queens of contortionist movements, they are the ones that are most in demand, and the ones that most control the movements together with the proprioceptors and the muscular golgi reticulum.
Joints are not mentioned in the answer because they are not a tissue, but a set of tissues.

Can traits of organisms be improved? Why? Explain.
Answer:
A single organism can not see an immediate improvement in their traits. Traits of a population can, however, be improved by means of microevolution. By this, I mean natural selection. Organisms with traits that are better suited towards an environment have a greater probability of surviving, meaning that there will be a larger output of offspring with these same traits. This causes gradual change and evolution over time, as more and more offspring receive traits that allow them to survive in their environment.

define prediction and how it is used form a hypothesis
Answer: upon previous measurements, observations, and experiments, that attempts to explain a natural system or part of a system. Following the scientific method, a scientist sets up an experiment to test the hypothesis.
Explanation:
A dairy farmer wanted to increase the amount of milk produced by his cows. He decides to test the effect of a particular feed additive. He gives half of his herd the additive. He maintains the amount of grazing time, the amount of water the cows drink per day, and even how often the cow gets chased by the local dog the same for all the cows. Each day the farmer milks the cows at the same time and compares the volume of milk.
Answer:
This question is incomplete; based on the understanding of the question, it aims at identifying the variables in the experiment conducted by the dairy farmer. The following variables will be provided in the answer: Independent, dependent, Control variable, Control group, Experimental group. The answers are:
Independent variable: FEED ADDITIVE
Dependent variable: AMOUNT (VOLUME) OF MILK PRODUCED
Constants: same amount of grazing time, the same amount of water the cows drink per day and the same frequency of how dogs chases the cows.
Control group: Herds that were not given the additive.
Experimental group: Herds that were given the additive
Explanation:
The independent variable in an experiment refers to the variable which is manipulated or changed in order to bring about a responding effect. The FEED ADDITIVE is the independent variable in this experiment.
The dependent variable is the variable that responds to the changes made to the independent variable. In this case, it is the AMOUNT/VOLUME OF MILK produced by the cows that responds to the effect of the feed additive, hence, it is the dependent variable.
In an experiment, a controlled variable or CONSTANT is the variable that is kept constant or unchanged throughout the experiment. In this case, the constants are the same amount of grazing time, the same amount of water the cows drink per day and the same frequency of how dogs chases the cows.
A CONTROL GROUP is the group that does not receive any experimental treatment in the experiment. It is used to compare the effect of the independent variable on the dependent variable. In this experiment, the control group are the HERDS that did not receive the feed additives.
The experimental group, on the contrary, are the groups that were subjected to experimental treatment. In this case, the experimental group are the HERDS that were given the feed additives.

Which is another word for 10 meters in the metric system? centimeter decimeter decameter hectometer
Answer:
decimeter
Explanation:deci means ten
Another word for 10 meters in the metric system is the decameter. Thus, the correct option for this question is C.
What is the metric system?The metric system may be defined as a system of measurement that significantly utilizes the meter, liter, and gram as base units of length (distance), capacity (volume), and weight (mass) respectively. In order to measure any small or large quantities, we use units derived from the metric system.
In the metric system, 10 meters is equal to 1000 centimeters. While 10 meters is equal to 100 decimeters. 10 meters is equal to 0.1 hectometers. While 10 meters is equal to 1 decameter. This unit we get from conversion factor.
