Answer:
The correct answer is - option A. Glass thermometer.
Explanation:
Glass or basal thermometers are the instruments that are use to measure temperature of any surface or organism. These are best choice for the measuring smaller changes in the temperature which can vary up to 1/10th of the degree to 1/100th of the degree.
In this case the temperature variation is 0.05 in the environment of the Toxicodendron diversilobum (poison oak) which can easily be monitor with the help of this glass temperature.
Thus, the correct answer is - option A. Glass thermometer.
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.

A sample of food is dehydrated, which kills all of the bacteria. However, in a few days, bacteria-free water is added to the food in a bacteria-free environment. Nevertheless, microscopic investigations indicate that bacteria are in the food. How did the bacteria get there?
Answer:
Because the cells in the dehydrated fruit become re-hydrated with the water which then gives the cells in both the water and the fruit the tools that it needs to "come alive" if you will. And the cells become active in the fruit and use the water to grow bacteria.

Adaptive features of Giant land snail
Answer:
Body Adaptations ; The eyes of water-dwelling and land snails have adapted to perch on two eye stalks that can retract and extend from the snails' bodies. These eye stalks slip inside-out when retracting, protecting the snails' eyesight from predators, turf wars and the elements.
Shell Adaptations ; Snails' shells protect them from predators .
Breathing Apparatus ; Freshwater and marine snails have evolved gills, while terrestrial snails sport fully formed lungs.
Secretions ; The slime that snails secrete (the mucus )is an adaptation that helps terrestrial snails survive out of water.
Breathing Apparatus ; Terrestrial snails sport fully formed lungs.

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.

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.
Therefore, another word for 10 meters in the metric system is the decameter. Thus, the correct option for this question is C.

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.
