explain why habitat loss and habitat division are threats to biodiversity

Answer:

bacteria are found everywhere even in hot springs. Bacteria are different from other organisms because they don't have membranes bound organelles .they replicates to produce

Explanation:

Bacteria can live in hotter and colder temperatures than humans, but they do best in a warm, moist, protein-rich environment that is pH neutral or slightly acidic. There are exceptions, however some bacteria thrive in extreme heat or cold, while others can survive under highly acidic or extremely salty conditions.

Many types of bacteria, if environmental conditions become unfavourable (lack of water, increase in temperature, etc), will go into a sort of dormant state, called an Endospore.

Because bacteria are prokaryotic, they do not have a nucleus and no membrane-bound organelles. In contrast, plants and animals are made up of eukaryotic cells, which means they have a nucleus and membrane-bound organelles like mitochondria or Golgi apparatus.

Bacteria reproduce through a process called binary fission. During binary fission, the chromosome copies itself, forming two genetically identical copies. Then, the cell enlarges and divides into two new daughter cells. The two daughter cells are identical to the parent cell.

Answer:

The mouse and shrew bones were common to all three owls so they were not useful in identifying environments. The gopher bones were unique to the great grey owl of Alaska. Gophers are rodents that are successful in areas with soft soil and lots of grass, so the gopher and this owl would be found in the meadows and evergreen forests of Alaska. The bat was unique to the barking owl of Australia. The bat would be found in woodland habitats where there are many trees the bat can hang from. The gull bones were unique to the short-eared owl of Cuba. Gulls are wetland birds, so the gull and this owl would be found in marshes and coastal areas.

Predators and their prey have various defensive weapons and behaviors to survive in a specific environment.

Prey animals employ camouflage, highly developed senses, warning signs, various defensive weapons and behaviors, and more to survive. A species adapts to blend in with its surroundings through the process of camouflage.

One species consumes the other species in a predator-prey interaction, the prey species is the animal that the predator feeds on, and vice versa.

Therefore, there is more food available for the survival and success of healthy prey species after predators take away vulnerable prey, such as the young, elderly, sick, injured, or very young.

Answer:

S - Savannas are typically found in tropical or subtropical regions.

S - Savannas tend to have more trees and shrubs.

S - Savanna's climate is drier than that of a grassland.

G - Grasslands are found in temperature regions.

G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.

G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.

B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.

B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.

B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.

Sound engineers use spongy materials, such as foam or fiberglass panels, on walls to absorb sound waves. These materials are porous and have irregular surfaces, which scatter and absorb sound, reducing the amount of sound that reflects off the walls and reducing echo and reverberation. This helps to improve the overall sound quality in a room or recording studio.

Sound engineers use spongy materials on walls to absorb sound.

As an audible mechanical wave, the sound is defined as vibrations that move through the air or another medium. It comes from a body that is vibrating. The medium (water, air, etc.) around the vibrating body vibrates, creating sound.

There are three different categories for sound waves. Audible sound waves are audible to humans. Low-frequency waves (below 20 Hz) are referred to as infrasonic waves. Waves of sound that are too high-frequency (over 20,000 Hz) for humans to hear are referred to as ultrasonic waves.

The properties of sound are frequency, wavelength, waveform, duration, amplitude, and pitch. Sound engineers use spongy materials on walls to absorb sound.

Answer:

A. The line leading a bracket around the balls, labeled A, represents the nucleus of the atom.

B. The white line, labeled B, is signaling the first main energy level, as per the quantum model of the atom.

Explanation:

You are describing the model of an atom with two protons, two neutrons, the electron density (orbital), and two electrons.

Then, you want to know what the labels A and B represent.

The nucleus of the atom is at the center, where protons and neutrons are placed. This is supported by three models: Rutherford's model, Bohr's model, and the (currently accepted) quantum model.

Hence, the red balls and the two overlapping balls in the center are representing the protons and neutrons.

The line leading a bracket around the balls, labeled A, represents the nucleus of the atom, since it is signaling both protons and neutrons in the nucleus.

The green fuzzy circular cloud depicts the region where the electrons are: it is fuzzy in correspondence to the quantum model, which states the electrons are not in a fixed position but in a region around the atom. That region is named orbitals. As per the model you cannot tell the exact position of the electron, and that is what the fuzzy cloud means.

In the the Bohr's model that white line,  which should be circular, where the electrons are, depicts the orbit of the electrons, and the shell, which were idenfified with letters L, M, N, K. The first shell was the L shell.

In the quantum  model, that line corresponds to the principal quantum number n, which is the main energy level. Hence, the line leading to a bracket overlapping the white line depicts the main energy level.

The atom is neutral because it contains the same number of electrons aroud the nucleus as protons inside the nucleus.

The tidal forces would be larger, seismic activity on the Earth would most likely be more pronounced/active.

The tidal force is a gravitational effect that stretches a body along the line towards the center of mass of another body due to a gradient in gravitational field from the other body.

Moreover, tidal forces are changes in the gravitational potential energy of the Sun, Moon and Earth. These forces cause the periodic motion of the seas which create a temporary change in water levels that vary depending on location.

Therefore, gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth.
