Why did zookeepers have such trouble keeping koala bears alive when other animals from Australia were thriving in zoos? Unlike m

ost Australian animals, koala bears require moderate temperatures to thrive. Zookeepers weren't feeding koalas the kind of food they require. Koala bears are susceptible to viral infections.

<span>Zookeepers have a difficulty of keeping koala bears alive because Koala bears are susceptible to viral infections. There is a virus that is present to Koalas which is called the Koala retrovirus. Koala retrovirus makes a Koala bear more susceptible to infections and even cancer. </span>

Answer:

Explanation:

A sequence of flowing lava, pyroclastic flows, volcanic eruptions, caldera-forming events, and earthquakes changed the landscape of Yellowstone forever. The pressure exerted by the magma chamber has resulted in measurable ground deformation in certain parts of Yellowstone known as resurgent pressure domes.

Fire Activity also causes the Yellowstone to change. As the number of very large wildfires and total acres burned annually increases, there is an increasing frequency of warm spring and summer temperatures, reduced winter precipitation, and early snowmelt in the Western United States during the last 20 years.

In 1995, the wolf population increased in Yellowstone, causing the deer population to decrease and to change their behavior. When threatened by wolves, deer graze less and move about to aerate the soil.

In the 70 years since the wolves left Yellowstone, the entire ecosystem had collapsed into chaos, with coyotes running riot, and elks overgrazing willows and aspens. Without those trees, songbirds declined, beavers could not build their dams, and riverbanks eroded.

What is the correct sequence of events along an axon that follows a membrane reaching threshold potential?
Oksi-84 [34.3K]

As sodium ions diffuse inward, sodium channels open.

Membrane depolarization occurs.

Potassium ions spread outward as potassium channels open.

Membrane repolarization occurs.

<h3>What happens along an axon in the right order ?</h3><h3 />

An action potential, which is a fast change in membrane potential, develops when the membrane potential of a neuron's axon hillock hits threshold. There are three steps to this shifting change in membrane potential. Depolarization occurs first, then repolarization, and then there is a brief phase of hyperpolarization.

  • A depolarizing current causes an explosion of electrical activity known as the action potential. This indicates that the resting potential shifts toward 0 mV as a result of some action (a stimulus).

Answer: it’s fertilization

Explanation: Fertilization in flowering plants happens through a process called pollination. ... Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule. After fertilization occurs, each ovule develops into a seed. • Each seed contains a tiny, undeveloped plant called an embryo.
