Answer:
One method used by newborn mammals to generate heat is referred to as nonshivering thermogenesis. This method utilizes a protein channel called <u>thermogenin</u> which is present in high levels inside the mitochondria of <u>brown adipose tissue.</u>
Explanation:
Thermogenin forms a proton channel in the inner mitochondrial membrane in the brown adipose tissues. Most of the newborn mammals have these brown adipose tissues. In these tissues, the oxidation of nutrients do not produce ATP but generate heat. The heat is used by the newborn to maintain the warmer body temperature. The process is called nonshivering thermogenesis.
The answer is C because there is no inference in the statement like the others.
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 correct answer is it causes immediate pathogen lysis.
Explanation:
The complement system is a part of innate immune system which is called first line of defense mechanism of our body.
complement system along with various proteins and enzymes stimulate the phagocytic cells to attack the plasma membrane of foreign pathogen,Which ultimately result in the lysis of foreign pathogen by phagocytosis mechanism.
