If you wanted to try and identify or classify archaea or eubacteria, you would study their habitat, study their genetic make-up, study their shape and arrangement, conduct Gram staining, study how they gain energy and nutrients and study how they move. Archaea and eubacteria are genetically different; Archaea have more complex RNA polymerases that contain multiple polypeptides while eubacteria have simple RNA polymerases that contain four polypeptides. Archaea cell walls do not contain peptidoglycan while almost all bacteria cell walls contain peptidoglycan.
Answer: Animal cells divide by a cleavage furrow. Plant cells divide by a cell plate that eventually becomes the cell wall. Cytoplasm and cell membranes are necessary for cytokinesis in both plants and animals.
Explanation:
Answer:
Sample Response: Cytokinesis occurs in both animal and plant cells. It is the division of the cytoplasm, which is the final stage of the cell cycle. In animal cells, the cell membrane pinches together around the middle of the cell to divide the cytoplasm. In plant cells, the process is a little different. Because the cell wall of a plant cell is rigid, it does not pinch in like the more flexible cell membrane in animal cells. Instead, a structure called a cell plate forms across the middle of the cell. The cell plate moves outward and eventually fuses with the cell membrane to divide the cell into two cells. Then, new cell walls form around the cell membranes.
Explanation:This is the sample response one e
genuity
B. Medical center
C. Paper mill
D. Oil refinery
Answer:
Option A, Leather tannery
Explanation:
In a leather industry, chromium is one of the heavy metals that are used in large amount.
Along with tannery, Chromium is also used in electroplating, and metallurgical industries.
The water coming out of these tannery has high content of chromium ion (Cr6+) generally ranging between 100–200 mg/L. This chromium rich water needs sufficient treatment before discharge or else it would cause bio magnification effect
Hence, option A is correct
C. A paper mill (APEX)
b. 1.00 g/cm3
c. 11.4 g/cm3
d. 19.3 g/cm3
Answer: /;
Explanation:
Answer:
Which process transfers heat from a hot pavement to a person sitting on it? Conduction
Explanation:
There are different mechanisms of heat transfer: Conduction, Convection, Evaporation and Radiation.
Conductionis in this case the right answer because is the process that thasnfers heat by physical contact. The contact in here would be the person and the hot pavement.
When it comes to convection, is the process that transfers heat by the movement of a fluid; evaporation is the process that transfers heat from liquid to gas and radiation is the process that we can see in the microwave which is transfering heat through energy.

The relationship between a dependent variable and independent variable in a scientific investigation is that the dependent variable depends on the independent variable. You can also put it this way: The results depend on the factor of the experiment that differs from the controlled group.
This is why the best way they could improve their experiment is by taking consistent amounts of their saliva samples with varying amounts of starch.
I hope it helps, Regards.
