Answer:
A producer. For example in a common food chain, grass->grasshopper->mouse->snake->eagle. The grasshopper eats grass which is a producer so if there aren't anymore insects like grasshoppers, then the grass grows more.
Answer:
The correct option is C.
Explanation:
There are three modes of heat conduction, these are conduction, convection and radiation. Heat transfer by conduction usually involves the movement of heat through solid substances. For instance, in the scenario given in this question, the warm surface is the solid substance through which heat is passed to the insects' bodies. Thus, conduction requires direct contact.
Heat transfer by convection method usually involves the movement of heat through liquids or gases while radiation can occur in vacuum.
Answer:
An experiment where an antibiotic is tested against bacteria. The antibiotic can vary in its concentration for example, different amounts are applied to a sample of bacteria to see if it is affected by the action of the antibiotic and if so, in what concentration. So, the independent variable is the concentration of antibiotic while the dependent variable is the survival (or not) of the bacteria.
Explanation:
An independent variable is a variable that represents a quantity that the scientist modifies in an experiment. A dependent variable represents a quantity whose value depends on how the independent variable is modified. This is the variable being studied and measured.
So, an example of this applied to bacteria or viruses could be:
<u>An experiment where an antibiotic is tested against bacteria</u>. The antibiotic can vary in its concentration, different amounts are applied to a sample of bacteria to see if it is affected by the action of the antibiotic and if so, in what concentration. So, the independent variable is the concentration of antibiotic while the dependent variable is the survival (or not) of the bacteria.
To complete the experiment, an antibiotic whose effect is already known can be used as a positive control. That is, it is already known to kill the bacteria. And as a negative control you can simply use water, which has no effect and is known not to kill the bacteria. In this way, we validate the results and make sure that there is not something else that is affecting the bacteria and that only the antibiotic being studied has an influence.
Answer:
The cranial nerves are the set of 12 pairs of nerves which are originated from the brain. As they are responsible for some of the essential functions , such as vision, smell, and balance of the human body structure.
<u>The 12 pairs of the cranial nerves are as as under:</u>
- The olfactory nerve
- The optic nerve
- The oculomotor nerve
- The trochlear nerve
- The trigeminal nerve
- The abducens nerve
- The facial nerve
- The vestibulocochlear nerve
- The glossopharyngeal nerve
- The vagus nerve
- The spinal accessory
- The hypoglossal nerve,
- It is very hard for the students to remember all the names of the cranial nerves as we can just recall them by memorizing the device-<em>Old Opie Occasionally Tries Trigonometry And Feels Very Gloomy, Vague And Hypoactive.</em>
Explanation:
The optic chasma originates as one of the cranial nerves, as it serves for the function of vision sense in human body. The nerves are responsible for carrying the set of information and data from the retina of the eye to the brain. As the communication between the two regions or part of the body, as they hold the capacity to carry the charges or information from the retina of the eye towards the brain.
