Animal cells have a cell membrane and not a cell wall. They have ribosomes and lysosomes and their nucleus is enveloped by a nuclear membrane. This means that the first description;
Cell membrane present;
ribosomes present;
lysosomes present;
nuclear membrane present.
Matches ANIMAL.
Plant cells on the other hand have something called a cell wall, which are more rigid than cell membranes. Plant cells are known for their large vacuole. They also have a nuclear membrane that covers its nucleus.
The third description:
Cell wall present
Ribosomes present
Nucleus present
Large vacuole present
Matches PLANT.
Viruses do not have any membrane on its wall nor its nucleus. Basically, they have no internal structures. The fourth and last description:
Reproduces inside of a cell
Nucleus absent
RNA present
Matches VIRUS
Prokaryotes are primitive cells and they do have a cell wall but they have no defined nucleus, which means they do not have a nuclear membrane. The second description:
Cell wall present
Ribosomes present
Nuclear membrane absent
Matches PROKARYOTE

Explanation:
if she has 15 and she put those 5 in a fish bowl well give her 10 then a lager tank that well give her 5 and then she putes those 5 in the pond she has used all her ghost shrimp
The tissue is higher plants that constitutes the vascular system, consisting of phloem and xylem by which water and nutrients are conducted throughout the plant.
Digoxin is a sodium potassium adenosine triphosphatase (Na+/K+ ATPase) inhibitor.
Digoxin is a group of drug that has most effects on cardiac tissues. Digoxin was first isolated from the plant <em>Digitalis lantana </em>that was found to be a sodium potassium adenosine triphosphatase (Na+/K+ ATPase) inhibitor. This drug when taken through mouth, gives a 60 to 80% bioavailability .
This drug blocks the sodium potassium adenosine triphosphatase (Na+/K+ ATPase) pumps of the myocardium. When the sodium pumps are closed, this leads to the increase in extracellular levels of sodium.
As the extracellular sodium increase, this indirectly blocks the sodium calcium exchanger which in normal conditions exchange 1 intracellular calcium in exchange of 3 extracellular sodium ions.
As this pump is blocked, this leads to increase in intracellular levels of calcium. This calcium levels also increase in the sarcoplasmic reticulum. Thus, the contractibility of the heart muscles per beat increase which helps to pump blood more effectively. Thus, the effect seen is positive intropic effect.
