which zone in the ocean is the most challenging to survive in?
Answer:
The Bathyal zone is the hardest to survive in.
Explanation:
Technically, the entire ocean is difficult to survive in. There's no oxygen and lots of scary ocean predators.
But the Bathyal zone, which is 1000 - 4000 meters below the surface of the ocean has no sunlight, making most of the sea creatures there have no eyes. Because this zone is so dark, with little food to survive in, fish don't hang out here.

What evidence did Galileo provide to support Copernicus's heliocentric model? Check all that apply.
Galileo determined the shape of each planet's orbit by a mathematical method called triangulation from different
points on Earth's orbit.
Galileo created a model showing the epicycles of the planets, which explained retrograde motion.
Galileo used a telescope to study the moons orbiting Jupiter. This showed that Earth was not the center of all
things.
U Galileo explained that people did not see stellar parallax because the stars were simply other suns that are very
far away.
Galileo discovered the phases of Venus, proving that at least one planet orbited the Sun.
Intro
Done
Answer:
- Galileo used a telescope to study the moons orbiting Jupiter. This showed that Earth was not the center of all things.
-Galileo discovered the phases of Venus, proving that at least one planet orbited the Sun.
Explanation:
Galileo discovered evidence to support Copernicus’ heliocentric theory when he observed four moons in orbit around Jupiter. Beginning on January 7, 1610, he mapped nightly the position of the 4 “Medicean stars” (later renamed the Galilean moons). Over time Galileo deduced that the “stars” were in fact moons in orbit around Jupiter.
At about the same time, German mathematician Johannes Kepler was publishing a series of laws that describe the orbits of the planets around the Sun. Still in use today, the mathematical equations provided accurate predictions of the planets’ movement under Copernican theory. In 1687, Isaac Newton put the final nail in the coffin for the Aristotelian, geocentric view of the Universe. Building on Kepler’s laws, Newton explained why the planets moved as they did around the Sun and he gave the force that kept them in check a name: gravity.

Which animal trait was Darwin’s theory of natural selection based on?
Camouflage or coloration is an animal trait that is based on Darwin's theory of natural selection.
What do you mean by Natural selection?Natural selection may be defined as the process through which populations of living organisms adapt and change. Natural selection leads to favorable variations among the organisms.
Coloration is the general appearance of an organism as determined by the quality and quantity of light that is reflected or emitted from its surfaces. These are determined by some dominant traits in organisms.
Therefore, Camouflage or coloration is an animal trait that is based on Darwin's theory of natural selection.

Why is water pollution a concern if water is continuously cycled through Earth's systems?
Answer:The Earth's Water Cycle involves Evaporation, Condensation, and Precipitation. Evaporation purifies the water resulting to the replenishment of freshwater to the Earth.
Water pollution is a concern despite of the water being continuously cycled through Earth's systems because the source of pollution is has not been removed.
Water pollution is defined as the contamination of bodies of water. Pollutants are directly or indirectly released to the bodies of water causing the water to be polluted.
Imagine: A river is filled with garbage, it is polluted. The water from the river undergoes the water cycle but since the garbage is still present in the river, the freshwater that comes from precipitation becomes polluted.

O A. They are both involved in cellular respiration in animal cells.
O B. They both contain chloroplasts and chlorophyll.
O C. They are both places where ATP is produced.
O D. They are both the sites of glycolysis.
Based on the information in the table, which of the following best explains why this bug population has changed since the introduction of the invasive plants?
o The bugs are unable to feed on native fruits.
Bugs with longer mouthparts have a survival advantage.
Bugs with smaller body lengths have a helpful adaptation.
o The bugs have started cross-breeding with a larger species.
The bug population has changed since the introduction of the invasive plants the bugs are unable to feed on native fruits.
Why the population of bug decrease?The population of bug decrease because the invasive plants reduce the population of native plants on which the bug feed. If the food for the bug decreases then the population of the bug is also decreases.
So we can conclude that the bug population has changed since the introduction of the invasive plants the bugs are unable to feed on native fruits.

peak phenomenon
sigmoid phenomenon
Answer:
The correct option is "D", the sigmoid phenomenon because Populations that exhibit the sigmoid pattern increase rapidly while food and habitat are abundant, and then slow down as regulatory factors such as lower birth rate and reduced food availability come into play. As the rate of population growth slows down to zero, the population reaches a fairly stable level.

Sally made a diagram to show one way that Earth's systems interact near a volcano
1. Identify the process that sally is moldering in her diagram
2. Explain how the individual parts shown in the model come together to form a cycle
The process that Sally is modeling in her diagram is the "Role of Volcanoes in the Earth's Systems". This particular system is called "the Cycle of Rock and Soil formation"
How do the individual parts of the model form the cycle?The cycle of soil formation starts with the production of molten magma by the volcano.
The magma solidifies and cools, then they are transported, deposited and go through lithification.
After lithification, they become sedimentary rocks, and then through exposure to pressure, they become metamorphic rocks.
Over the years, as more and more layers are deposited onto the metamorphic rocks, pressure and heat build up creating molten magma.
The magma creates igneous rocks which after many years may be produced again as molten magma through an active volcano.

describe five different breath sounds that may be heard when you check a client's respiration
1. Rales. Small clicking, bubbling, or rattling sounds in the lungs. They are heard when a person breathes in (inhales). They are believed to occur when air opens closed air spaces. Rales can be further described as moist, dry, fine, or coarse.
2. Rhonchi. Sounds that resemble snoring. They occur when air is blocked or air flow becomes rough through the large airways.
3. Stridor. Wheeze-like sound heard when a person breathes. Usually it is due to a blockage of airflow in the windpipe (trachea) or in the back of the throat.
4. Wheezing. High-pitched sounds produced by narrowed airways. Wheezing and other abnormal sounds can sometimes be heard without a stethoscope.
5. crackles (a high-pitched breath sound)

what gender tachycardia affects most?
Ostriches and gazelles feed next to each other. They both watch for predators and alert each other to danger. Since the visual abilities of the two species are different, they each can identify threats the other animal would not as readily see.
commensalism, parasitism, or mutualism
Answer: This would be an example of mutualism.
Explanation: Mutualism is when, in a certain situation, benefits both organisms. The gazelles and ostritches in this situation are both watching for predators and are making sure to alert each other to the danger that could spring nearby. Both of these animals can locate predators in different ways. Ostritches are capable of seeing predators from in the tall grasses, while the gazelles are able to hear predators with their great hearing. Together, these two creatures make a great defense. Both the gazelles and ostritches benefit. This is known as mutualism.
