Answer:
Option B, chemical energy to thermal energy
Explanation:
All living organism feed on food that contains energy in the form of chemical energy. Once the food is intake and processed for fulfilling energy requirement of all metabolic processes with in a cell, the remaining energy is released as heat (thermal energy). Thus, an amoeba while consuming a sugar molecule converts chemical energy with in the sugar to thermal energy in the form of energy molecules.
Hence, option B is correct
Answer:
C
Explanation:
because a population is a group of the same species that lives in a given area
Answer:
3 characteristic
Explanation:
1- it contains sulfur when bacteria found sulfur in the media then it produces H2S (hydrogen sulfate). It causes the blackening of the media which acts as an indicator that bacteria can produce H2S.
2- Indol is the second characteristic. If bacteria is indol positive than it changes color from yellow to pink when the reagent is added.
3- Motility: if bacteria are motile than it's motility is easily visible in the media.
Answer:
d.) All of the above
Explanation:
Prophase is the first stage of mitosis. In this phase, the DNA condenses into chromosomes. The nuclear membrane breaks down, and the centrioles move to opposite sides of the cell.
The next phase is metaphase, where the condensed chromosomes move to the centre of the cell.
Next, during anaphase, the chromosomes are separated to either end of the cell
Finally, during telophase and cytokinesis, the nuclear membrane reforms and the chromosomes begin to decondense, and the cytoplasm splits to form two cells.
