How would human activity would escalate the effects of natural disasters

Biology
2 answers:
docker41 [41]3 years ago
5 0

Answer:

Although humans can sometimes influence natural disasters (for example when poor levee design results in a flood), other disasters that are directly generated by humans, such as oil and toxic material spills, pollution, massive automobile or train wrecks, airplane crashes, and human induced explosions, are considered.

Because hazards are threats of harm mainly to human systems, human activities play a large role in how severe a hazard is. For example, when large numbers of people crowd into floodplains and low-lying areas, they are putting themselves in harm's way, increasing the severity of potential floods.

Which portion of the cerebral cortex is most closely adjacent to the ears?
ikadub [295]
<span>The temporal lobes is a portion of the cerebral cortex that is most closely adjacent to the ears. Its function is a responsible for processing auditory information from the ears (hearing). It is mainly revolves around hearing and selective listening and receives sensory information such as sounds and speech from the ears. Furthermore, it is also a key to being able to comprehend or understand meaningful speech. Thus, we would not be able to understand someone talking to us if it wasn’t for the temporal lobe. Lastly, this love is special because it makes sense of all different sounds and pitches that is being transmitted from the sensory receptors of the ears. </span>

What organisms can get up to 10 centermeters in size
Svetach [21]
<h2><u>Answer:</u></h2>

A Single-Celled Organism

<h2><u>Explanation:</u></h2><h3><u></u></h3>

The giants of the deep are so-called xenophyophores, sponge-like animals that—like amoebas—are made of just one cell. They were found during a July research expedition run by the Scripps Institution of Oceanography in La Jolla, California.

The animals are about four inches (ten centimeters) long—among the largest single-celled organisms known to exist.

The creatures were discovered at depths of 6.6 miles (10.6 kilometers). That breaks a previous record for xenophyophores found in the New Hebrides Trench at 4.7 miles (7.6 kilometers).

Xenophyophores represent, <u>"one of the few groups of organisms found exclusively in the deep sea,"</u> said Lisa Levin, a Scripps oceanographer who studied the expedition's data.

<u>"If any creatures should be able to live at the ocean's greatest depth, then xenophyophores certainly should be among them."</u>

The Mariana xenophyophores were seen in footage from Dropcams, free-falling devices equipped with lights and digital video that were developed by the National Geographic Society. (The Society owns National Geographic News.)

Protected by thick walls of pressure-resistant glass, the Dropcams were baited to attract whatever marine life might be lurking in the deep. Expedition scientists also saw, for instance, the deepest-swimming jellyfish to date. (Watch a video of the expedition.)

<u>"The deep sea is the largest biome on Earth and holds much of the diversity on the planet—[yet it's still] largely undescribed,"</u> Levin said in an email to National Geographic News.

(Also see, <u>"Pictures: Hard-to-See Sea Creatures Revealed."</u>)

According to Jon Copley, a marine biologist at the U.K.'s University of Southampton, <u>"many of the major discoveries in deep-sea biology have come from making direct observations at the seafloor."</u>

<u>"The Dropcam is a great tool for the future, because it can help us see more of what's down there for less cost than using ROVs or submersibles,"</u> he said via email.

For instance, <u>"finding xenophyophores far deeper than before shows how much we still have to learn about our oceans depths and their inhabitants."</u>

Tullis Onsott, an expert in deep-sea microorganisms at Princeton University, also called the xenophyophore discovery, <u>"fantastic."</u>

An extreme disturbance happens in an ecosystem. How does an ecosystem change as succession happens after this disturbance?
ddd [48]

Answer:

There is less biodiversity in the ecosystem.

Explanation:

Since the barren ground doesn't provide suitable living conditions for most of the living organisms, the ones that need the lest resources to survive create the primary succession, usually the mosses and lichens. The organisms of the primary succession provide biomass, so the ground is mixing with it, thus new soil is forming.

Suppose you were in charge of sending an unmanned space probe to a new planet in search of life. The probe would be able to coll
Svetlanka [38]

Answer:

Option D, a test for the presence of cells that contain DNA

Explanation:

As we know all living organisms are made up of cells and DNA is the basic genetic material that codes for protein and traits with an organism. If even a single cell with DNA is detected on the extraterrestrial planet then it will be clear that it has life on it or the environmental conditions are favorable to support life. Cells are microscopic and hence can be seen through microscope which can be installed easily on a probe.

Hence, option D is correct
