Answer:
D, over the past Billions of years, our atmosphere has formed to protect life.
Answer:
The population of insect eater birds are decreasing due unavailability of food.
Explanation:
If the population of insects in an ecosystem decreases, so the organisms which feed on them i. e. insect eater birds also decreases and die due to hunger. In an ecosystem, every organism is the food of other organism, if one organism is eliminated or reduced in population, then the other organisms will also be affected.
DNA polymerase is an enzyme which is needed for the synthesis of new DNA strand on the old DNA template. In order to synthesize new DNA strand, DNA polymerase requires many other enzymes or molecules such as:
1. All four deoxyribonucleotides triphosphates
2. Single stranded DNA template
3. Inorganic phosphate 3')H end of new DNA strand
During DNA replication, the double stranded DNA molecules mush unwind and form single stranded structures so the both the strands can be replicated simultaneously.
Answer:
In the cone pathway glutamate: ... Glutamate that is released from the photoreceptors in the dark binds to metabotropic glutamate receptors (mGluR6), which, through a G-protein coupling mechanism, causes non-specific cation channels in the cells to close, thus hyperpolarizing the bipolar cell.
Explanation:
Answer:
Dependent variable - increase in water level
Melting rate of ice - independent variable
Explanation:
Independent variables usually refers to the set of conditions, values or constraint used or adopted by an experimenter or researcher in other to cause a change in the measured variable also called the dependent variable.
The independent variable is therefore purposely used to depict or show changes in the dependent variable. The dependent variable is the measured variable whose behavior or output lies on the value of the independent variable.
In the scenario above, the dependent variable is the increase in water level,as it is what is being measured. And it is dependent on the Melting rate of ice, which is the independent variable.
That is change in water level in the cup, depends on the rate at which ice melts
