Place the following taxa in order of "inclusion of fewest number of species" to "inclusion of most number of species". 1. Domain
aalyn [17]

Answer:

1)Genus 2)Family 3)Order 4)Phylum 5) Domain

Explanation:

Species is a large group of living organisms that can breed freely among themselves, exchange genes and produce offspring.

Taxonomic rank is the group of living organisms that are related to each other and most basic rank is species. The lower the rank the smaller it be and contain most similar organisms.

The higher rank comprises by combining of smaller ranks like in your question the family contain many genus and order contain many families and so on. Thatswhy most higher rank would contain maximum number of species.

How does the introduction of invasive species, such as the brown tree snake, upset the stability of an ecosystem?
notka56 [123]

Answer:

The species is not prey to what is already living there and as a result may reproduce uncontrollably and end up causing the other species to go extinct by stealing the resources they need.

What factors drive the movements of global air masses
maksim [4K]

Answer:

The 4 types of air masses are polar, tropical, continental and maritime. Their classification depends on their location where they are formed.

Explanation:

One major influence of air mass movement is the upper level winds such as the upper level winds associated with the jet stream. The jet stream wind is often referred to as a steering wind. The troughs and ridges of the jet stream will help transport cold air toward lower latitudes and warm air toward high latitudes.

1. List and explain the difference between the minimum voltage and maximum voltage achieve in a nerve impulse
algol [13]
The normal membrane potential inside the axon of nerve cells is –70mV, and since this potential can change in nerve cells it is called the resting potential. When a stimulus is applied a brief reversal of the membrane potential, lasting about a millisecond, occurs. This brief reversal is called the action potential 
<span>A stimulus can cause the membrane potential to change a little. The voltage-gated ion channels can detect this change, and when the potential reaches –30mV the sodium channels open for 0.5ms. The causes sodium ions to rush in, making the inside of the cell more positive. This phase is referred to as a depolarisation since the normal voltage polarity (negative inside) is reversed (becomes positive inside). </span>

<span>Repolarisation. At a certain point, the depolarisation of the membrane causes the sodium channels to close. As a result the potassium channels open for 0.5ms, causing potassium ions to rush out, making the inside more negative again. Since this restores the original polarity, it is called repolarisation. As the polarity becomes restored, there is a slight ‘overshoot’ in the movement of potassium ions (called hyperpolarisation). The resting membrane potential is restored by the Na+K+ATPase pump.</span>

Adaptations of the chloroplast​
zepelin [54]

Answer:

Chloroplasts are the ’solar energy plants’ of a cell – they convert light energy into chemical energy

This chemical energy may be either ATP (light dependent) or organic compounds (light independent)

Only photosynthetic tissue possess chloroplasts (e.g. is present in leaves but not roots of plants)

Chloroplasts are thought to have once been independent prokaryotes that were internalised by eukaryotes via endosymbiosis

They have a double membrane structure (due to vesicular coating as part of the endocytotic process)

They have their own DNA (circular and naked) and ribosomes (70S)

Their metabolic processes are susceptible to certain antibiotics

The structure of the chloroplast is adapted to the function it performs:

Thylakoids – flattened discs have a small internal volume to maximise hydrogen gradient upon proton accumulation 

Grana – thylakoids are arranged into stacks to increase SA:Vol ratio of the thylakoid membrane

Photosystems – pigments organised into photosystems in thylakoid membrane to maximise light absorption

Stroma – central cavity that contains appropriate enzymes and a suitable pH for the Calvin cycle to occur

Lamellae – connects and separates thylakoid stacks (grana), maximising photosynthetic efficiency
