Answer:
B
Explanation:
Chemistry starts with the atom as this is the building block of all chemistry.
The cell, nucleus, and enzyme are all part of biology and not chemistry (at this level at least)
The answer is Amoeba; pseudopod; Euglena; flagellum; paramecium; cillia.
Protozoan are organism, usually single-celled and heterotrophic belonging to any of the major lineages of protists and, like most protist, protozoa are microscopic. all protozoans are eukaryotes and therefore possess a true or a membrane-bound nucleus. Examples of protozoa include; Amoeba, Euglena, Paramecium. They exhibit diverse modes of locomotion across the various groups, but the modes of locomotion can be broadly divided into flagellar, ciliary, and amoeboid movement.
The question is incomplete. The complete question is as follows:
Which of the following is not true regarding fenestrated capillaries?
A) Fenestrated capillaries in endocrine organs allow hormones rapid entry into the blood.
B) Fenestrated capillaries in the small intestine receive nutrients from digested food.
C) Fenestrated capillaries are essential for filtration of blood plasma in the kidney.
D) Fenestrated capillaries form the blood-brain barrier.
Answer:
Fenestrated capillaries form the blood-brain barrier.
Explanation:
The fenesterated capillaries are small fine thin capillaries that helps in the exchange of substances. These capillaries are mainly found in the kidney, small intestine and glands.
The fenestrted capillaries allow the exchnage of hormone in the blood and in the kidney for the filtration. The nutrients can be easily exchanged by the capillaries present in the small intestine. The blood brain barrier function is not performed by the fenesterated capillaries. They allows the rapid exchange function and not as the barrier.
Thus, the correct answer is option (D).

Explanation:
Basic Definitions:
Cell Membrane = the semi-permeable structure that surrounds the cell and keeps all of the cells organelles from exploding everywhere.
Cell Wall = the rigid 'armor' of the cell that surrounds it after the membrane. Usually made up of cellulose and ONLY found in plant cells.
Nucleus = A really dense organelle of the cell usually surrounded by two membranes. They contain and protect your genetic material. Basically everything that makes you, you.
Cytoplasm = The watery, salty, and protein filled 'soup' that fills the cell. All organelles float happily in this.
Now Specific Locations:
Eukaryotic cells
have plasma membranes
please mark me brainliest or mark me thanks at leat
only have cell walls if the cells are plants.
They do have a nucleus.
They have cytoplasm
Prokaryotic cells
have plasma membranes
cell walls are usually chemically complexed.
don't have a nucleus
have cytoplasm
Animal cells
only have the plasma membranes.
No cell wall
have a nucleus
have cytoplasm
Plant cells
have both the cell wall
and have a plasma membrane
have a nucleus
have cytoplasm
Answer:
The nervous system is made up of all the nerve cells in your body. It is through the nervous system that we communicate with the outside world and, at the same time, many mechanisms inside our body are controlled. The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain. Metabolic processes are also controlled by the nervous system.
