Which statement about plasma membranes is correct? (1 point)
O Animal cells have cell membranes instead of plasma membranes,
O Both plant cells and animal cells have flexible plasma membranes.
O Plant cells have cell walls instead of plasma membranes.
O Plant cells have rigid plasma membranes.
The statement that is true about plasma membrane is that Animal cells have cell membranes instead of plasma membranes.
What is plasma membrane?The plasma membrane is the membrane found in all cells separate inside of the cell from outside environment. In bacterial and plant cells, a cell wall is attached to the plasma membrane from the outside surface .The plasma membrane consists of a lipid bilayer that is semipermeable. The plasma membrane help to transport of materials inside and outside the cell.
Therefore, plasma membrane is the membrane in cells that separate the outside from the inside of the cell.

Why as viruses described as particles rather than cells?
Answer: A single virus particle is known as a virion, and is made up of a set of genes bundled within a protective protein shell called a capsid.
Viruses do not have nuclei, organelles, or cytoplasm like cells do, and so they have no way to monitor or create change in their internal environment. A virus is not a living thing. And they cannot do anything on their own until they enter a living cell. Without cells, viruses wouldn't be able to multiply.

A weed? % the same as me A fruit fly? % the same as me A mouse? % the same as me A chimpanzee? % the same as me.
Gene is taken into consideration as the essential gadget of DNA. The similarity in DNA sequences of various organisms replicates a not unusual place ancestry, which seems to be shared with the aid of using all organism's gifts on earth.
Human DNA suggests very much less similarity with weeds' (vegetation) DNA, that's around 18%. Thus, vegetation display one-of-a-kind metabolic capabilities from human beings, consisting of photosynthesis.
Human DNA suggests around 26% similarity with yeast (fungus) DNA, as yeasts have a few housework genes, equal to genes found in human beings. For example, genes to uptake strength from sugar breakdown.Human DNA suggests 44 % similarity with fruit fly (insect) DNA. Mammals, consisting of human beings and bugs percentage genes, which might be chargeable for their increase and structures.Human DNA suggests 92 % similarity with the DNA of mice as they each are mammals and a percentage many, not unusual place genes.Human DNA suggests 98 % similarity with the DNA of chimpanzees. That is why chimpanzees are taken into consideration as closest relatives of human beings.What is DNA?
DNA is a coiled structure that has a loop that is twisted and has ciloing.
It also has nucleotides sequence for amino acids.
Therefore is clear that all the percentages of DNA calculated are given above.
