when a prairie dog spots a predator, it responds by giving an alarm call, but only when close relatives are near. this is an example of vocalization.

<h3>What do you mean by predator ?</h3>

The interaction between prey and a predator, where the energy flow occur called as predation and the organism feed on other organism called as predator and the food means the other organism is called as prey.

Predators can be carnivores and omnivores like Lions, tigers, sharks, and snakes, all are predators, it can fall prey to other large animals E.g. a snake is a predator to a mouse, but prey to a hawk.

Carnivorous predators directly kill and eat their prey like large animals such as the lion and tiger, they have their own mode of feeding.

Herbivore are plant eating animals like cows, buffaloes, goats, sheep, and deer; parasites are also under the category of predators which is a host dependent and live, get nutrients from host's body for survival and reproduction.

What challenges do you think parasites face in their survival? How can these challenges affect the parasite?

Greeley [361]

Parasites need a host. If a host tries to get rid of the parasite or kill it, then the parasite either has to leave the body or die.

Select the correct answer from each drop-down menu. alexis is out mowing the lawn and starts to feel dehydrated. her will secret

Anuta_ua [19.1K]

Her hypothalamus will secrete vasopressin. If her dehydration becomes severe, her secretion of vasopressin will increase.

<h3>What is vasopressin?</h3>

The posterior pituitary gland releases the peptide hormone vasopressin, also known as antidiuretic hormone.
Which is produced by the supraoptic and paraventricular nuclei of the hypothalamus (neurohypophysis).

It primarily functions as an anti-diuretic in the kidney, where it causes the body to reabsorb water by acting on the distal region of the nephron when it is dehydrated.
The AVP gene for it is found on human chromosome 20.
Vasopressin has an antidiuretic effect; it reduces the volume of urine by raising the collecting tube's water permeability.
It attaches to the G protein-coupled V2 receptor, which in turn starts a signaling cascade through the PKA.
Aquaporin 2 (a transmembrane pore) is produced as a result, and it is then transported to the apical/urinary membrane.

24. An investigator examines voltages resulting from changes in membrane permeabilities. If the cell membrane suddenly had 100 p

omeli [17]

Answer:

Generally, K+ ions ensures re-polarization of the membrane potential. It always ensures that the neuron returns its resting state, protecting the neurons and ensuring episode of rest before the next action potential.

K+ does this by leaving the axon, making the inner layer more negative. This is resting membrane potential. Because there are many K+ channels for leakages out of the neuronal axons.

Therefore, in this scenario, he neuron will return to its resting membrane potential state which between values -50 to -75mV.

Therefore the value of the potential will be -60mV, or within the range of -50 to -60mV. This is because the neuron is is non- excitable.
