Kingdom Monera was the oldest kingdom of living organisms. The organisms in the kingdom were simple, single celled and their cellular organelles were not covered by membranes. Prokaryotic bacteria were the first known Monerans. However, scientists think that Monerans were evolved into more complex eukaryotic organisms (Protists) with the passage of time.  

But how did Monera (Prokaryotes) was evolved into Protista (Eukaryotes)?

  • Monerans to Protists

Protista are eukaryotes, unicellular or simple multicellular organisms.Many theories were proposed for this evolution, but one that makes most sense was endosymbiotic theory. According to this, the first eukaryotic cells were evolved when two prokaryotic cells existed in an endo-symbiotic relationship. Larger prokaryotic cells engulfed smaller prokaryotic cells. The smaller cells got shelter and nutrients from larger cells and both co-existed in a mutualistic relationship. Both cells eventually evolved into organelles and got never aparted. This is how more complex organisms’ protists were evolved from simple monerans. It was a gradual process and took millions of years.

  • Protists to Fungi

The earliest fungi were single-celled organisms that contain a flagella to move from one place to another. Recent studies indicate that fungi belong to a group of organisms which were evolved from protists over the course of time. These studies are based on the nucleotide sequence of fungi that matches to a large extent with old protists. It is estimates that fungi evolved 600 million years  or even before.

frosja888 [35]

Answer:

A scientific model is a representation model for a certain scientific concept. Scientific models make it easier to study a phenomenon as they tend to model out the exact phenomenons.

A drawing of an skeleton would be unclear as the children might not be able to locate certain features in the drawing. For example, a certain joint could be missed by the teacher in the drawing or the child might not exactly be able to locate where the joint or bone is present.

But as the model will be more real to the actual skeleton system hence, studying through a skeleton will make it a lot easier to study the human skeletal system.

Answer:

ATP stands for adenosine triphosphate. It is a molecule found in the cells of living organisms. It is said to be very important because it transports the energy necessary for all cellular metabolic activities. Without ATP, various metabolic activities in the human body cannot take place.

SSSSS [86.1K]
1. Action potential reaches the axon terminal and depolarizes it.

2. Depolarization opens voltage-gated calcium channels, enabling influx of Ca into the neuron.

3. Calcium binds to specialized proteins on vesicles (containing pre-made acetylcholine) and triggers them to fuse with the neuron membrane at the synapse.

4. Exocytosis of acetylcholine into the synaptic cleft occurs.

5. Acetylcholine diffuses across the synapse and binds to nicotinic receptors on the end plate of the myocyte.

6. Activated nicotinic receptors, themselves ion channels, cause cation influx into the myocyte and generate an end plate potential. This eventually gives rise to the full depolarization within the myocyte that enables contraction.
