1. A rabbit can cover a distance of 80 min 5 s. What is the speed of the rabbit?
Answer:
[tex]\boxed {\tt 16 \ m/s}[/tex]
Explanation:
Speed can be found by dividing distance by time.
[tex]s=\frac{d}{t}[/tex]
The rabbit travels 80 meters in 5 seconds.
The distance is 80 meters and the time is 5 seconds.
[tex]d= 80 \ m \\t- 5 \ s[/tex]
Substitute the values into the formula.
[tex]s=\frac{80 \ m }{5 \ s}[/tex]
Divide.
[tex]s= 16 \ m/s[/tex]
The rabbit's speed is 16 meters per second.

The statement "I was the maiden who was loved by Zeus, was transformed into a heifer so that Hera wouldn’t find me," is the moon named as Io, a figure in Greek mythology, and it was discovered by Galileo Galilei in 1610 and is named after the mythological character.
What are jupiter's moons?
Io is one of the four largest moons of Jupiter and the fourth largest moon in the solar system. It is named after the mythological character Io from Greek mythology, who was a priestess of Hera and was transformed into a heifer by Zeus to protect her from Hera's jealousy. Io is known for its intense geologic activity, with over 400 active volcanoes and volcanic plumes that can reach heights of over 300 kilometers (190 miles) above the surface. The high levels of volcanic activity are due to tidal forces from Jupiter and its other large moons.
Hence, the correct answer is Io, a figure in Greek mythology, as it was the moon discovered by Galileo Galilei in 1610 and is named after the mythological character.

Which of the following hazards can severely harm a worker's lungs?
heat exposure
vehicle hazards
bins and silos
excessive noise
Which of the following hazards can severely harm a worker's lungs?
A). Heat Exposure.
Explanation:
In terms of weather/overall Heat: Inhaling hot air, induces airway constriction making it difficult to breathe. This can be especially so with people with lung conditions. It's also found that this can cause COPD and many respiratory air conditions.
In terms of fire: Of course, it's known that smoke from fire can have a terrible effect on your lungs. It can restrict oxygen flow, which can and most likely be deadly.
Why it's not the other options:
b). Vehicle Hazards: This one would most likely have no or little correlation with lung health. Also, it's not specific enough.
C). Bins and silos don't have as much effect on the lungs as Heat exposure does.
D). Excessive noise would effect mainly the ears, not lungs.

Three fourth of the total earth is covered with water, 97 percent of which is there in sea's as saline water, the other 2 percent is there in the form of glaciers and the left out 1 percent is there as ground water.
Water is presence is abundance but it depends upon the geographical location where the animal is looking for water. There will be scarcity of water in the deserts because there is less rainfall over there, so it depends on the geographical location.
A student used a microscope to observe Elodea submerged in a solution. The student observed the cell cytoplasm pull away from the cell wall and clump together in the center of the cell. Which statement best explains why this occurred? A-The cell was submerged in a hypertonic solution. B-The cell was submerged in a hypotonic solution. C-The cell was submerged in a pure solution. D-The cell was submerged in an isotonic solution.
Answer:
A
Explanation:
The correct answer would be that the cell was submerged in a hypertonic solution.
A hypertonic solution is a solution with a higher concentration of solutes than that of the cytosol of a cell suspended in it. When a cell is suspended in a hypertonic solution, water moves osmotically from the cytosol to the hypertonic solution. This causes the cytoplasm to collapse and the cell becomes flaccid.
The correct option is A.
Answer:
D. The cell was submerged in a hypertonic solution.

The Devil's Hole water system is part of a large underground aquifer in Death
Valley National Park. After the last lce Age, around 10,000 years ago, as the
water dried up and the land tumed to desert, separate pools of water formed.

few of these water holes and springs and then evolved different (adaptive /
disruptive / stabilizing) traits to become distinct species over time. This kind of
(polygenic drift / genetic drift / environmental effect) likely occurred because
each water pool was inhabited by a few surviving individuals of the original larger

_________are organisms capable of transforming one
form of energy (light energy or chemical energy) into the food
they need to do work.
Answer:
Producers/Autotrophs
Explanation:
Using carbon dioxide and water, plants convert carbon dioxide into glucose, and water into oxygen with the help of light energy to provide food for themselves. In a process called photosynthesis.
The organism that is capable of transferring one form of energy, which is light energy, to chemical energy, which is food, is the photoautotroph. These are the producers in the ecosystem, such as the plants.
What is the role of the photoautotroph?Every ecosystem contains some form of photoautotroph, such as land plants present in the terrestrial ecosystem, phytoplankton present in the aquatic ecosystem, etc. The photoautotrophs have special cell organelles, such as the chloroplasts, that carry out the conversion process of the light energy into chemical energy by the different complexes present in the thylakoid. ATP is formed during the photosynthesis process, and the carbon level in the atmosphere decreases as the plant uses it for this process.
Hence, the organism that is capable of transferring one form of energy, which is light energy, to chemical energy, which is food, is the photoautotroph. These are the producers in the ecosystem.

What do you still wonder about why the fossils of Mesosaurus that once lived together are found in different locations on Earth now?
Answer:I got You guys yall are like family here is the answer
Explanation: What I still wonder about the Mesosarurus that once lived together are found on different locations of the world. One question is what if the animals did swim across the mid ocean ridge? Another question I have is why would the plate boundaries separate for example what caused the divergent plate to suddenly start moving. My last question is why would the plate boundary not suddenly move apart but move gradually over time apart from one another.
The fossils of Mesosaurus that once lived together are found in different locations on Earth now due to a variety of reasons like a mid-ocean ridge, movement of plate boundaries, and continental drift.
What do you mean by Fossils?Fossils may be defined as the dead and organic remains of past living organisms including plants and animals that were buried and preserved deep in the soil millions of years ago.
According to the context of this question, the fossils that once lived together are found in different locations on Earth now itself due to numerous reasons which are described above. These reasons are responsible for some fragmentation of the earth's surface and these fossils were shifted to the part where they are hard or impossible to find.
But in this modern era of science and technology, each and everything is possible to search out. So, this might be the possible reason for the appearance of fossils of Mesosaurus that once lived together are found in different locations on Earth now.

4. A scientist is observing living Cells in a Petri Dish under a Compound Light Microscope and recorded their
observations. Which of these observations provides evidence to support one of three components of "The Cell
Theory?" (SC.6.L.14.2)
a. Each Cell is spherical in shape.
b. Cells appear pink in color under the Microscope.
c. The sample of Cells require a nutrient broth as a food source.
d. Several Cells are in the process of dividing into two new Cells.
Answer:
D. Several cells are in the process of dividing into two new cells
Explanation:
The universal cell theory which was proposed in 1838 and contributed by three scientists namely: Theodor Schwann, Rudolf Virchow, and Mathias Schleiden, consists of three components namely:
1) Cell is the basic and functional unit of life
2) All living organisms are made up of one or more cells.
3) All existing cells arise from pre-existing cells.
Hence, in this question involving a scientist who is observing living Cells in a Petri Dish under a Compound Light Microscope, the observation that "Several cells are in the process of dividing into two new cells" provides evidence to support one of the three components of the cell theory ( all living cells arise from preexisting cells).
