Plant and animal cells are very similar because they are both eukaryotic cells.
Answer:
I think the correct answer is D
Answer:
B
Explanation:
An undifferentiated cell is such as that in a blastocyte. They are multipotent and can differentiate into any type of cells. The cells of the mass begin to have their gene differentially expressed (due to differential silencing of particular genes) hence the cell become determined. They become well organized into tissue such as skin and other organs.
Answer:
Zebra mussels feed on phytoplankton, which zooplankton need as a food source.
Explanation:
The population of zooplankton in Lake Erie and the Hudson River declined due to the arrival of zebra mussels because Zebra mussels feed on phytoplankton, which is the main source food of zooplankton. So due to limited or scarcity of food in the environment, the zooplankton die due to hunger that leads to the decrease of population of zooplankton in that environment.
The equation which is correct according to ohm’s law is v = ir which is denoted as option D.
<h3>What is Ohm’s law?</h3>
This states that the voltage across a conductor is directly proportional to the current flowing through it.
This is deduced as V ∝I where v is voltage and I is current.
V = IR
