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.
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.

"Create a bar graph comparing the particle movement in hot water to that in cold water."
A camel is lost in the desert. It is not finding any food or water. It needs 9000 kilo calorie energy and 4 litre water daily. Its mass is 650 kg and 10% of its mass is fat. It has a water reservoir near its neck with a reserve of 312 litre water. It can live using its fat storage. 1g fat contains 9 kilo calorie energy. How long the camel can survive with it's reserve?
The correct answer to how long the camel can survive with its reserve would be 65 days.
First, let us calculate the total amount of energy derivable from the fat in the body of the animal:
Mass of the camel = 650 kgMass of fat = 10% of the total mass= 10% x 650 = 65 kg
If 1g of fat is equivalent to 9000 kilocalories of energy in the animal, then, 65 kg of fat would be equivalent to:
65 x 1000 x 9000 = 585,000 kilocalories of energyThe total amount of energy is 585,000 kilocalories and the total amount of reserved water is 312 litres:
Amount of energy required per day = 9000 kilocaloriesNumber of days 585,000 kilocalories of energy can serve = 585,000/9000= 65 days
Amount of water needed per day = 4 litresNumber of days 312 litres of water can serve = 312/4= 78 days
The water reserve can last 78 days while the energy reserve can last 65 days. Since the camel needs both to survive, it means the animal can only survive for 65 days.

Describe 2 limitations of a 3D cell model.
Will mark brainliest!!!
Answer:
One of the major disadvantages of 3D cultures is that there is a requirement for the separation of single cells from spheroid structures by proteolytic degradation of single layers, which can take several hours or even a few days. There are many 3D methods where the efficiency, lifespan, repeatability, along with the comfort of work are poorer than in the case of 2D systems, which again is a disadvantage.
Explanation:
3D methods have become a lot more prevalent and are used in the area of cancer research, they can also be applied in tissue engineering. Cell culture is a commonly utilized in vitro tool for expanding our understanding of cell biology, tissue shape, disease mechanisms, medication action, protein production, and tissue engineering development. The majority of cancer biology research is based on in vitro experiments with two-dimensional (2D) cell cultures. However, because 2D cultures have numerous limits, 3D is utilised.

Explanation:
The amoeba excretes waste through _________ while a sparrow excretes waste through __________.
Answer:
The amoeba excretes waste through Contractile Vacuole while a sparrow excretes waste through Cloaca.
Explanation:
In some unicellular eukaryotic organisms (e.g., amoeba), cellular wastes, such as ammonia and excess water, are excreted by exocytosis as the contractile vacuoles merge with the cell membrane, expelling wastes into the environment.
Birds, unlike mammals, do not have separate exits for urine and feces. Both waste products are eliminated simultaneously through the cloaca. While mammals excrete nitrogenous wastes mostly in the form of urea, birds convert it to uric acid or guanine, which reduces water loss in comparison.

Yes, we all know Pluto is no longer an official planet, merely a dwarf, but it still enjoyed full planet status when New Horizons rocketed from Cape Canaveral, Florida, on Jan. 19, 2006. Plutos demotion came just seven months later, a sore subject still for many.Were kind of running the anchor leg with Pluto to finish the relay," Stern says.The sneak peeks of Pluto in recent weeks are getting "juicier and juicier," says Johns Hopkins project scientist Hal Weaver. "The science team is just drooling over these pictures."The Hubble Space Telescope previously captured the best pictures of Pluto. If the pixelated blobs of pictures had been of Earth, though, not even the continents would have been visible.The New Horizons team is turning "a point of light into a planet," Stern says.An image released last week shows a copper-colored Pluto bearing a large, bright spot in the shape of a heart.Scientists expect image resolution to improve dramatically by Tuesday. The 7,767-mile span at closest approach is about the distance between Seattle and Sydney.New Horizons, weighing less than 1,000 pounds including fuel, has seven instruments that will be going full force during the encounter. Its expected to collect 5,000 times as much data, for instance, as Mariner 4.Were going to rewrite the book," Weaver says. "This is itthis is our once-in-a-lifetime opportunity to see it."The team gets one crack at this.Were trying to hit a very small box, relatively speaking," says Mark Holdridge, the encounter mission manager. "Its 60 by 90 miles, and were going 30,000 mph, and were trying to hit that box within a plus or minus 100 seconds."The only planet in our solar system discovered by an American, Pluto actually is a mini solar system unto itself. Plutojust two-thirds the size of our own moonhas big moon Charon thats just over half its size, as well as baby moons Styx, Nix, Hydra, and Kerberos. The names are associated with the underworld in which the mythological god, Pluto, reigned. New Horizons will observe each known moon and keep a lookout for more.Scientists involved in the 700 million effort want to get a good look at Pluto and Charon, and get a handle on their surfaces and chemical composition. They also plan to measure the temperature and pressure in Plutos nitrogen-rich atmosphere and determine how much gas is escaping into space. Temperatures can plunge to nearly minus-400 degrees.Bill McKinnon, a New Horizons team member from Washington University in St. Louis, Missouri, expects to see craters and possible volcanic remnants. A liquid ocean and a rocky core may lie beneath the icy shell.Anybody who thinks that when we go to Pluto, were going to find cold, dead ice balls is in for a rude shock," McKinnon says. "Im really hoping to see a very active and dynamic world."Pluto has tantalized astronomers since its 1930 discovery by Clyde Tombaugh using the Lowell Observatory in Flagstaff, Arizona. Some of Tombaughs ashes are aboard New Horizons. His two children, now in their 70s, plan to be at Johns Hopkins for the encounter.With its tilted, elongated 248-year orbit, Pluto has made it only a third of the way around the Sun since its discovery. The amount of sunlight that reaches Pluto is so dim that at high noon, it looks like twilight here on Earth. The massive surrounding Kuiper Belt, in fact, is called the Twilight Zone. The New Horizons team has its eyes on a few much smaller objects in the Kuiper Belt, and is hoping for a mission extension as the spacecraft continues toward the solar system exit on the heels of NASAs Voyagers 1 and 2 and Pioneers 10 and 11.For now, signals take 4hours to travel one way between New Horizons and flight controllers in Maryland.New Horizonsscience instruments will be cranked up to collect maximum data Tuesday, leaving no time to send back data. In fact, scientists wont be absolutely certain of success until Tuesday night, 13 hours following New Horizonsclosest approach, when it "phones home."It will be Wednesday before the closest of Plutos close-ups are available for release. And it will be well into next yearOctober 2016before all the anticipated data are transmitted to Earth.

Two heterozygous dominant parents for attached earlobes are crossed to predict the traits of their offspring. What is the ratio of attached earlobes to unattached earlobes in their offspring?
A - 3:1
B - 1:3
C - 2:2
D - 4:0
Answer:
A - 3:1
Explanation:
In order to determine what number of offspring will have attached earlobes, we must make a Punnett table. We know that attached earlobes are the dominant gene, and we know unattached earlobes are recessive.
| P | p
——————-
P | PP | Pp |
——————-
p | Pp | pp |
As we can see, only one out of the four squares has two recessive genes. Therefore, our answer would be A - 3:1.

Which water cycle processes usually cause a lowering in the water table? Which processes cause a rise?
Answer:
Explanation:
Lowering: During the summer months, the water table tends to fall, due in part to plants taking up water from the soil surface before it can reach the water table. The water table level is also influenced by human extraction of groundwater using wells; groundwater is pumped out for drinking water and to irrigate farmland.
Rise: Fluctuations in the water table level are caused by changes in precipitation between seasons and years. During late winter and spring, when snow melts and precipitation is high, the water table rises.
The water table typically drops throughout the summer because plants absorb water from the soil's surface before it can get to the water table.
What is Water table?Human groundwater extraction through wells, including pumping out groundwater for drinking water and farmland irrigation, has an impact on the water table level as well.
Variations in precipitation over the course of seasons and years are what create fluctuations in the water table level. The water table rises in the late winter and early spring as snow melts and precipitation levels are high.
The five steps of the nitrogen cycle, which are fixation or volatilization, mineralization, nitrification, immobilization, and denitrification. The fixation process is known as volatilization in this image because soil bacteria convert nitrogen gas (N2) into volatile ammonia (NH3).
