Explain homeostasis and why it’s important to the body
Answers
Answer:
Homeostasis regulates your body. When you are too hot, your body produces sweat to cool you down. When you're cold, you muscles shiver to generate warmth. When you have high glucose levels in your blood, your pancreas excretes insulin, and when blood glucose is too low, then it excretes glycogen. Homeostasis basically keeps your body from losing control and it helps you survive.

If the gasoline floats on the surface of the puddle, what does that tell you about how its density compares to that of water? Explain your answer.
Answers
It tells that gasoline is less dense than water, because according to Archimedes Law states that any body completely or partially submerged in a fluid is acted upon by an upward, or buoyant, force, the magnitude of which is equal to the weight of the fluid, displaced by the object. So, when gasoline is put in water, it floats, it means that the buoyancy force is greater than gasoline's weight. It means that the weight of the same volume of water is more than the weight of the same volume of gasoline. It means that water has more density.

It is theorized that the continents on Earth were once joined together,
forming a supercontinent called Pangaea. How long ago did Pangaea
exist? How were the continents of Africa and South America arranged in
relation to each other? Describe one piece of evidence to support their
relationship. Write your response in complete sentences
Answers
Answer:
Pangea existed many millions of years ago in many opinions, but it started back in the late Paleozoic Era until the very late Triassic. Pangea first began to be torn apart when a three-pronged fissure grew between Africa, South America, and North America. Scientists have found fossils of similar types of plants and animals in rocks of similar age. These rocks were on the shores of different continents. This suggests that the continents were once joined. For example, fossils of Mesosaurus, a freshwater reptile, have been found both in Brazil and western Africa.
Explanation:
Answer:
Pangaea is believed to have existed around 335 million years ago during the late Paleozoic and early Mesozoic eras.
During this time, the continents of Africa and South America were joined together as part of the supercontinent Pangaea. They were located in the southern hemisphere, with Africa to the east and South America to the west.
One piece of evidence to support their relationship is the similarity of plant and animal fossils found on both continents. Fossils of the ancient reptile Mesosaurus have been found in both Africa and South America, indicating that the two land masses were once connected. The distribution of fossils of other plant and animal species also suggests that Africa and South America were once part of the same landmass.
The theory of Pangaea and continental drift was first proposed by Alfred Wegener in the early 20th century, and it has since been supported by a range of geological and paleontological evidence. The movement of the continents has had a profound impact on the evolution of life on Earth, as it has created new habitats and allowed for the evolution of new species in isolation.

Answer: Encourage students to set up a germination experiment by placing the seeds in different conditions, such as light vs. dark, or wet vs. dry. Moreover, they need to pot the same seed in more than one pot.
Explanation:
This option provides a clear and practical approach to the seed germination investigation. By setting up different conditions for the seeds, such as light vs. dark or wet vs. dry, the students can observe and compare how these conditions affect the germination process. Additionally, potting the same seed in multiple pots allows for a controlled comparison within the experiment.
By manipulating these variables, the students can gather valuable data and observations regarding the influence of light and moisture on seed germination. This approach promotes a hands-on and investigative learning experience, encouraging students to actively engage with the scientific process while documenting the changes that occur over time, such as the emergence of roots and shoots.

it’s melting
From the diagram of the rock cycle the missing part is ( B ) ; Melting
Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.
Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting

3.) What time of the day does the sea breeze occur? (night time or day time)
4.) Which heats faster, land or sea?
5.) Compare the direction of air in sea breeze and land breeze.
Answers
PLS MARK ME AS BRAINLIEST
1.) As a result, warm air rises. Therefore, the warmer air over the land surface is rising. As the warm air over the land is rising, the cooler air over the ocean is flowing over the land surface to replace the rising warm air.
2.) a cool wind that blows from land to water. On clear, calm evenings, temperature differences between a body of water and neighboring land produce a cool wind that blows offshore. This wind is called a "land breeze".
3.) While sea breezes occur during the day, land breezes occur at night.
4.) Since land absorbs more solar radiation the land surface retains more heat as do the vegetation for energy. Thus, land surfaces warm more quickly than water.
5.) Sea breeze carries increased moisture, which it absorbs while blowing over a water body. A Land breeze is drier since it has no opportunity to absorb water from any source. Lastly, the sea breeze moves from the sea towards a land body. A Land breeze moves from land toward a water body, generally a sea or ocean.
Answer: 1.) During a sea breeze, the air moves from the sea towards the land. During the day, the land heats up faster than the sea. As a result, the air above the land becomes warmer, and it rises. The cooler air from the sea moves towards the land to replace the rising warm air, resulting in a sea breeze.
2.) During the land breeze, the wind blows from the land towards the sea. At night, the land cools faster than the sea. The air above the sea remains warmer and rises, and the cooler air from the land moves towards the sea, resulting in a land breeze.
3.) The sea breeze occurs during the daytime.
4.) Land heats up faster than water. This is because water has a higher specific heat capacity than land. Specific heat capacity refers to the amount of energy required to increase the temperature of a substance. Water requires more energy to heat up compared to land, which is why it heats up slower than land.
5.) During a sea breeze, the direction of air is from the sea towards the land. During a land breeze, the direction of air is from the land towards the sea.

what direction does the moon revole around earth
Answers
Answer:
West to East if I am not mistaken.
Explanation:
Answer: The direction the moon revolves around the earth is Prograde direction.
Explanation: The moon orbits the Earth once every 27.322 days. It also takes approximately 27 days for the moon to rotate once on its axis. As a result, the moon does not seem to be spinning but appears to observers from Earth to be keeping almost perfectly still. Scientists call this synchronous rotation. The side of the moon that perpetually faces Earth is known as the near side. The opposite, or "back" side is the far side. Sometimes the far side is called the dark side of the moon, but this is inaccurate. When the moon is between the Earth and the sun, during the new moon phase, the backside of the moon is bathed in daylight. The orbit and the rotation aren't perfectly matched, however. The moon travels around the Earth in an elliptical orbit, a slightly stretched-out circle. When the moon is closest to Earth, its rotation is slower than its journey through space, allowing observers to see an additional 8 degrees on the eastern side. When the moon is farthest, the rotation is faster, so an additional 8 degrees are visible on the western side.

Create a hypothesis that can be tested in an experiment.
Remember, a hypothesis has a specific "if then" wording.It describes what will happen to the dependent variable when changes are made to the independent variable.For example, "If a plant is fertilized (independent variable), then it will grow faster (dependent variable)."
Design and plan an experiment.
Be sure to identify an independent variable, a dependent variable, and any controls.Remember, controls are factors which stay the same.In an experiment designed to test the previously stated hypothesis, one control would be to use the same kind of plant.Write a complete description of your experiment.Include a list of necessary materials.It is a good idea to follow a step-by-step procedure format.Think of everything you need to do, then write it down in the order it must be completed.Your description and procedure should be clear enough that another person could duplicate your experiment exactly.
Answers
Answer: E
Explanation:
Experiment Design:
Independent Variable: Intensity of light (Low, Medium, High)
Dependent Variable: Rate of photosynthesis (measured by oxygen production or CO2 consumption)
Control: Same kind of plant, constant temperature, constant CO2 concentration, constant water availability, and constant duration of light exposure.
Materials:
Three identical potted plants (of the same species)
Light source(s) with adjustable intensity
Light meter (lux meter) to measure light intensity
CO2 gas sensor or oxygen gas sensor
Timer or stopwatch
Water supply
Thermometer
Data recording sheets
Procedure:
Set up the three identical potted plants in a controlled environment with the same temperature and CO2 concentration.
Ensure that all plants receive the same amount of water.
Place the light source(s) at an equal distance from the plants.
Measure and record the initial light intensity using the lux meter.
Adjust the light intensity to low for the first plant, medium for the second plant, and high for the third plant.
Start the timer and expose the plants to light for a specified duration (e.g., 1 hour).
During the exposure period, measure and record the temperature, CO2 concentration (if possible), and light intensity at regular intervals.
After the exposure period, use the CO2 gas sensor or oxygen gas sensor to measure the change in CO2 concentration or oxygen production, respectively, in the surrounding air.
Record the data obtained from the sensors and calculate the rate of photosynthesis for each plant.
Repeat the experiment multiple times to ensure reliability and average the results.
Analyze the data collected and compare the rates of photosynthesis among the three different light intensities.
Draw conclusions based on the analysis and determine whether the hypothesis is supported or rejected.
By following this experimental design, you can test the hypothesis and determine the effect of light intensity on the rate of photosynthesis in plants. Remember to conduct the experiment in a controlled environment and gather sufficient data for accurate analysis.
