Answer:

Extremophiles

Explanation:

Extremophiles are organisms that have been discovered on Earth that survive in environments that were once thought not to be able to sustain life. These extreme environments include intense heat, highly acidic environments, extreme pressure and extreme cold. Different organisms have developed varying ways of adapting to these environments, but most scientists agree that it is unlikely that life on Earth originated under such extremes.

Some students believe that if they drink a glass of milk before bed and would make them sleep longer what’s the independent vari

miss Akunina [59]

Answer:

Independent variable: Glass of milk

Dependent variable: Time of sleep

Control variable: same type of milk

Explanation:

Independent variable in an experiment refers to the variable that the experimenter manipulates or changes in order to get a response in another variable (dependent). In this case, the independent variable is the GLASS OF MILK taken before bed.

Dependent variable is that variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the dependent variable is the TIME OF SLEEP of the students.

A control variable or constant is the variable that is kept unchanged throughout the course of the experiment in order not to alter the outcome of the experiment. In this experiment, a control variable can be the SAME TYPE OF MILK taken by each student.

A biologist at a highly prestigious biology conference presented an informative speech on how DNA in genetics works. All audienc

Arada [10]

The question is incomplete as it does not have the options which are:

A. novelty

B. creativity

C. consensus

Answer:

A. novelty

Explanation:

Novelty refers to a qualitative identity that is used to represent the new ideal things or some fresh and refreshing ideas.

In the given question, the person who was presenting about the idea of How DNA works in genetics? failed to present something new about the DNA and just presented what was already known to the audience.

Since the presenter failed to express the new ideas in his presentation about the DNA that is no novel ideas were presented therefore the audience started to leave the presentation.

Thus, Option-A is correct.

Proton pumps embedded in the cell membrane use ATP to move hydrogen ions across the membrane. Which of the following best descri

DIA [1.3K]

Answer:

Explanation:

Although protons resemble other positive ions such as Na+ and K+ in their movement across membranes, in some respects they are unique. Hydrogen atoms are by far the most abundant type of atom in living organisms; they are plentiful not only in all carbon-containing biological molecules, but also in the water molecules that surround them. The protons in water are highly mobile, flickering through the hydrogen-bonded network of water molecules by rapidly dissociating from one water molecule to associate with its neighbor, Protons are thought to move across a protein pump embedded in a lipid bilayer in a similar way: they transfer from one amino acid side chain to another, following a special channel through the protein.
