Answer:

Inhibit control over ions.

Explanation:

The immediate effect of the neurotoxin on the postsynaptic neuron is to inhibit control over ion concentrations across the cell membrane. The neurotoxin blocks nervous transmission at synapses which prevents the vesicles containing the neurotransmitter from fusing with the presynaptic membrane so the information does not transfer from one neuron to another and as a result the body is present at constant relaxation mode. The membrane potential of postsynaptic neuron will decrease due to neurotoxin.

Sense a dog has 78 chromosomes in their body cells and humans have 46, are dogs more complex than humans do to have a more chrom
Ksivusya [100]

Answer:

No

Explanation:

A carp (a kind of fish) has 104 and a rattlesnake fern has 184. Most likely neither of these is as complicated as we are (especially the fern).

These kinds of differences are out there because the number of chromosomes doesn’t have anything to do with how complicated or “advanced” a living thing is. What matters is what is on them.

Your fewer chromosomes have the set of instructions for making you and a potato’s chromosomes have the set of instructions for making a potato plant. It doesn’t matter how many pieces those instructions are cut up into.

Think about it like comparing the instructions for building a car to the instructions for building a bicycle.

Let’s say the car’s instructions are in one big book but the bicycle’s instructions are spread over five books. Making a bicycle isn’t more complicated than a car just because it is in five books instead of one. Same thing with your chromosomes and a potato’s chromosomes.

It also doesn’t always have to do with how many “pages” or even sets of instructions are in something’s chromosomes.

Shrimp are primary consumers that feed on photosynthetic organisms. why would these organisms likely be found only in shallow oc
astra-53 [7]
Since shrimp pray on photosynthetic organisms, they are dependant on their prey's location.
The photosynthetic organisms need sunlight in order to produce energy, so they then to live in shallow waters, because the sunlight penetrates only a small upper layer of the water's surface.
So, shrimp live in shallow waters because their pray can only live there.

andrew-mc [135]

The missing part of the question is -

" Is this Primary or Secondary Succession?"

Answer:

The correct answer is - secondary succession.

Explanation:

Recolonization of the plant and animals to habitat after a major disturbance such as flood, lava eruption, wildfire, or human disturbance is characterized as secondary succession.

In this particular case, there is secondary succession occurs, there is man-made disturbance tajes place as logging company clear the spruce trees from a habitat, and after clearing the land the spruce seedlings began to sprout, birds, rabbits recolonize to the area.
