Answer:
yes the wall is pushing back.
Explanation:
This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted.
Answer:
IT IS BEST FOR A CELL TO HAVE A LARGE SURFACE AREA AND A SMALL VOLUME. THEREFORE, A LARGE SURFACE AREA TO VOLUME RATIO IS MORE DESIRABLE.
Explanation:
Answer:
The correct answer is - osmosis.
Explanation:
Paramecium lives in freshwater like the Potomac River which is hypotonic to the cytosol of the paramecium. Paramecium uses contractile vacuoles to transport the water from the lower concentration (outside of the cell) to a high concentration of solvent to the inside of the cells.
This process of cell transport is carried out by osmosis as their cytoplasm contains a higher concentration of solutes outside the cell. This excess water is collected into vacuoles called contractile vacuole that swells and finally internalized the water to the outside of the cell.
Thus, the correct answer is - osmosis.
Answer:
Mitochondria
Explanation:
In the eukaryotic cells, some cell organelles and membranes together make a membrane system called the endomembrane system. This system includes the endoplasmic reticulum, Golgi apparatus, lysosomes and nuclear membrane. Members of this system works together. They modify, package, and transport lipids and proteins. The lysosomes formed from Golgi apparatus and contains hydrolytic enzymes. Mitochondria is the site for cellualr respiration and is not a part of the endomembrane system.
Answer:
This composition of nucleotide given in the question do not obey the chargaff"s rule.
Explanation:
According to chargaff"s rule the total number of purine bases will be same to the total number of pyrimidine bases that is
Adenine+Guanine=Thymine+Cytosine
But here the above quation is not maintained because according to the question A+G=49%
and T+C = 51%.
Such DNA is replicated by rolling circle model.
