The 2 major components or parts that compose or make up the plasma membrane of a eukaryotic cell would be the phospholipids arranged as a bilayer, having phospholipids arranged side by side in an upright and inverted manner, allowing for the hydrophobic and hydrophilic regions to interact respectively, and also Protein molecules, more specifically Transmembrane Proteins and Integral Proteins.
Answer:
Bacterial population shown in the graph is of Exponential type.
Explanation:
When the rate of population increases over time in proportion to the population size, it is known as exponential growth of population. Bacterial reproduction happens in an hour time span for many bacterial species by splitting itself in half.
This shows how the exponential growth occurs in bacteria. The amount of population gets increased with added organisms in generations of species.
Answer: Somatic nervous system
Explanation:
The voluntary nervous system or somatic nervous system the part of the PNS (peripheral nervous system) which is associated with the voluntary control of the body movements.
These movements are generally controlled by the skeletal muscles. It helps in various movements such as walking, bending, sitting, et cetera.
This nervous system consists of the efferent nerves and afferent nerves or we can say motor nerves that helps in controlling the movement of the body.
Answer:
b. During replication there is both a leading strand and a lagging strand
.
c. Each replication bubble has two replication forks.
Explanation:
Eukaryotic chromosomes have multiple origins of replication to replicate the long chromosomes at a higher rate.
The two DNA strands have opposite polarity, that is, 5' end of the one DNA strand is present opposite to the 3' end of the other DNA strand. DNA replication occurs only in 5' to 3' direction and the direction of the movement of the replication fork is also 5' to 3' direction.
To allow the DNA replication in 5' to 3' direction on both strands, one strand is replicated discontinuously in the direction opposite to the movement of the replication fork.
The discontinuously replicated strand is lagging strand while the other one is the leading strand.
DNA replication in eukaryotes occurs bidirectionally as two replication forks are formed at each replication bubble, one at each end of the replication bubble.
The presence of multiple origins of replication and the bidirectional process allows the replication of large eukaryotic DNA at a considerable fast speed.
