Secondary succession is the kind of succession that might develop in a neighborhood park after the Zombie Apocalypse if the grass wasn't cut anymore and pioneer species would first colonize the bare soil.

Thus, pioneer species like weeds and grasses would colonize the bare soil and disturbed regions in the initial stage of secondary succession. These species can swiftly adapt to a new habitat since they are frequently resilient and rapidly developing.

In secondary succession, the pioneer species are the early settlers multiply and spread, the soil conditions become more stable and draw in additional species like shrubs and tiny trees. These animals are modifying the environment in a way that makes it possible for bigger and more diversified populations of creatures to live in more complicated settings.

pH indicates the level of H+ ions, where low pH indicates too many H+ ions and high pH. However, different body fluids have different pH values.

pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic.

Low-pH water will corrode or dissolve metals and other substances. Pollution can change a water's pH, which in turn can harm animals and plants living in the water.

The abnormalities in acid-base balance are of two types: acidosis and alkalosis. In acidosis, the blood pH is low or there is too much acid in the blood, while in alkalosis, the blood pH is high or there is too much base in the blood.

Frogs lives on lands due to its body structure and food availability. It has sticky tongue that captures insects.

Humans lives on lands not in water due to its body structure because its body structure can't allow humans to live in water due to absence of gills.

Seagull lives in the aquatic ecosystem because seagull feeds on fishes and other marine animals.

Sharks lives in water due to its body structure such as gills that are used to respire in water and the shark can't respire without water.

Meerkat lives in the arid climate because they lives underground to save themselves from the environment and the presence of food.

Protea lives in desert due to their dry skin that can tolerate the warm temperature.

Although the total distance the impulse travels in the reflex arc is less than 3 meters. the time taken is more than 0.04 seconds and the time taken is more than expected because of Synapses or due to gaps between neurons.

Diagram displays the whole reflex arcs from the tip of the finger to the spinal cord and then back out to a closer muscle, possibly in the forearm or the arm. Because the signal doesn't have to go all the way back to the finger, the total distance is less than 3 meters. Considering that it just travels back a portion of the way, less than 3 meters, it takes. Let's see, it takes more than twice as long, therefore the query makes us think about why the delay. Where is the hold-up what is happening there, and the key to this is that the gray matter of the spinal cord doesn't truly contain mylin, despite the fact that we said it- accelerates electrical conduction through the axon in the nerves of the extremities. Mylin has a whitish color, which contributes to the white matter's appearance of whitishness. Thus, the electrical signal becomes slower.

Itching and other skin problems are signs that a cat or dog may have flea. Fleas are parasites known for their biting and blood-sucking abilities. When they bite, flea saliva enters the pet’s circulatory system, sometimes causing an allergic response commonly seen as a “hot spot” on the pet’s neck or the base of its tail.

Fleas are tiny parasitic insects that infest the fur of dogs and cats. They feed on blood and cause skin irritation that results in itching. If the problem is severe, it can lead to more significant health issues. Pet owners should watch for signs of fleas and treat their pets promptly to avoid complications. Fleas lay eggs on the skin of dogs and cats, which hatch and develop into larvae.

The larvae feed on the skin, shedding as they mature. Adult fleas emerge from the larvae, biting the host to feed on blood. The process repeats itself, with adult fleas continuing to lay eggs on the skin of the pet.The most common sign of fleas in dogs and cats is itching. Pets will often scratch themselves, bite their skin, or lick excessively to relieve the irritation.

Other signs of fleas include red or inflamed skin, hair loss, and the appearance of small, raised bumps on the skin. These bumps are often referred to as "flea dirt" and are the waste products of the fleas. In severe cases, anemia, an allergic reaction, or the transmission of other parasites or diseases can occur.

Flea infestations can be treated with a variety of products, including topical treatments, shampoos, and collars. It is essential to follow the instructions on the product label and treat the pet and the surrounding environment to eliminate the fleas. Prevention is key to avoiding flea infestations, so pet owners should maintain a regular grooming and flea prevention schedule.

Most articles pass right through the atom, this means that most of the atom is an empty space.

An atom is described as a particle that consists of a nucleus of protons and neutrons surrounded by a cloud of electrons.

Protons and neutrons make up the core nucleus of an atom, which is encircled by an electron cloud. In relation to the size of the atom as a whole, the nucleus is exceedingly small.

As a result, the electrons surrounding the nucleus are the primary target of interactions when particles or even light pass through an atom. The majority of the atom's remaining space, which includes the nucleus, is vacant.

The structure of cardiac muscles help it perform its function as they have striations that allow for big movements.

Explanation:

Cardiac muscle is one of three types of vertebrate muscle tissue, with the other two being skeletal muscle and smooth muscle. It is involuntary, striated muscle that constitutes the main tissue of the wall of the heart. The cardiac muscle forms a thick middle layer between the outer layer of the heart wall and the inner layer, with blood supplied via the coronary circulation. It is composed of individual cardiac muscle cells joined by intercalated discs and encased by collagen fibers and other substances that form the extracellular matrix.

Hope this helps! :)

Explanation:

So basically, the Cardiac muscles stick together by intercalated disc. These discs, allow the Cardiac muscle cells to contract in a pattern so the heart can work as a pump.

A tiny electric message moves through a long part of a brain cell called the axon. When a message goes to the end of a nerve, it sends chemicals called neurotransmitters. These substances move through a tiny gap and attach to special parts of another nerve cell's outer covering.

Messages called impulses are sent from one nerve cell to another through a connection called a synapse. This process is called synaptic transmission. Synapses are connections between nerve cells or between nerve cells and other cells, like muscles or glands.

The neuron sending the signal is called the presynaptic neuron. When a signal travels down a nerve cell, it causes little sacs called vesicles to release chemicals called neurotransmitters.
