Answer:
B. False
Explanation:
Prior to the replication of a DNA strand or molecule, the double stranded DNA molecule needs to be unwound i.e. separated into two single strands. One strand called the LEADING STRAND that runs from the 3' - 5' direction while the other strand called the LAGGING STRAND runs from the 5' - 3' direction.
The unwinding of the DNA template is carried out by an enzyme called DNA HELICASE, which binds to the DNA molecule and unwinds the double strands into two strands at the same time. This means that the unwinding into leading or lagging strand is not easier than the other since it occurs simultaneously, hence, this question is FALSE.
Answer:
Explanation:
1- in passive transport there are 3types. One is diffusion, in which a molecule from the area of higher concentrations moves towards the area of lower concentration. Because diffusion is a type of passive transport that's why it is included in the method of it.
2- glucose is the simplest form of sugar. It moves from the cell membrane through the process of diffusion. Outside the cell level of glucose or it's concentration is high and inside the cell it's concentration is low. Though diffusion process glucose moves from the area of higher concentration to the lower concentration.
Oxygen is what animals need in order for Carbon Dioxide to be exhaled while breathing. This is part of what the Respiratory System does. Carbon also enters animals that are in contaminated environments such as living next to a factory or a polluted area.
Two things that can occur is water levels may rise and the earth can get warmer.
