Answer:
THE THREE MAIN COMPONENTS OF ANY PLANT OR ANIMAL CELL ARE:
1. PLASMA MEMBRANE/ CELL MEMBRANE
Structure- a bilipid membraneous layer composed of proteins and carbohydrates. It is fluid like.
Function - the cell membrane separates the cell from its external environment, and is selectively permeable (controls what gets in and out). It protects the cell and provides stability.
Proteins are found embedded within the plasma membrane, with some extending all the way through in order to transport materials.
Carbohydrates are attached to proteins and lipids on the outer lipid layer.
1.all living things are made up of cells
2.Cells are the smallest units of life
3.all cells come from preexisting cell though the process of cell division
Answer:
in a certain population of red squirrele, a mutation causes several squirrels to
be bom with darker coats. These coats make the squirrels nearly inweible
when they are foraging on the forest floor
, According to the theory of evolution by natural selection, what is likely to happen to this trait after several generations?
After several generations, this trait is likely to be much more common because individuals with the trait will have a greater chance of passing it on to their offspring,
Explanation:
It would later turn to what is termed as germline mutation which are mutations passed from parent to offspring, as time progresses the trait would be more and increases the chance of being transferred to their offspring
DNA replication
DNA replication is the process by which DNA makes a copy of itself during cell division. The first step in DNA replication is to 'unzip' the double helix structure of the DNA? molecule. ... The two separated strands will act as templates for making the new strands of DNA
