What are Uranus and Jupiter?Both Jupiter and Uranus are planets in our solar system. Jupiter, the largest planet in our solar system, is located five planets from the Sun. Uranus, the third largest planet in our solar system, is located at a distance of seven planets from the Sun.
Both planets are gas giants, with atmospheres composed mostly of hydrogen and helium. Their upper atmospheres also include methane gas, which gives them a blue-green colour. However, there are many differences between Uranus and Jupiter. Although they are much less noticeable than Saturn's rings, Uranus has a system of rings and at least 27 moons. Compared to Jupiter, Uranus is smaller and has less mass.
Therefore, the correct option is D.

Answer:
This looks like an earthquake
Explanation:
There doesn’t seem to be very much water present in the image which would be the cause for the rest of them
Hope this helps
Answer:
Earthquake
Explanation:
First off I wouldn't say landslide because if it was a landslide in more than likely would have cracked the concrete on the floor that the people are standing on and there would be more of a mess than what is show in the picture. Next I wouldn't say tsunami depending on how frequent this disaster was, if it was a tsunami more than likely most of that rubbish would have been soaked with water in other things that were in the water as well and I wouldn't say flood either because once again nothing is soaked with water with in that picture not even the concrete that the people are standing on so I say that the most reasonable answer would be earthquake due to them being know for destroying buildings alot.

bicycle tyres become flat when the weather is cold.Why?
Answer:
The tires lose air pressure in the winter because it contracts. If you have 35 lbs in the summer, with 85 degrees, when it gets cold, down to -10, your air pressure can get down to about 25 lbs. So before it gets bitter cold, inflate your tires up a little. You don’t want to be putting air in your tires once it is freezing out. Sometimes the schrader valve doesn’t seat properly because of frost and the rubber seal is hard. I have had several tires go flat on me because of this.

Pesticide resistance is increasing, Farmers in the US tost 7% of their crops to pests in the 1940s, over the 1980s and 1990s, the loss
was 13%, despite more pesticides being used. It is estimated that 500-1000 pests have developed a resistance to pesticides. Consider
the diagram showing the evolution of pesticide resistance. Select ALL of the statements that do NOT accurately describe the
mechanisms of pesticide resistance shown in the graphic.
A)Insects that are sensitive to the pesticide all die out after the first
application, leaving only the resistant insects in the population,
B)When insects are exposed to the pesticide, some will develop a mutationmaking it resistant. Only these insects survive in the next generation
C)The first generation has an insect with a gene responsible for resistance toa pesticide. This allows it to survive the pesticide application and reproduce
D)The insect with the pesticide resistance gene reproduces. Because these insects are more likely to survive pesticide application, insects with this
trait become more prominent in the population
E)As a population of insects is exposed to a pesticide, those susceptible to
the pesticide will die out of the population, leaving those with a resistance
to survive and reproduce, becoming more common in the population
The insect with the pesticide resistance gene reproduces, these insects are more likely to survive pesticide application hence insects with this trait become more prominent in the population
What is a pesticide?A pesticide refers to a chemical that is used to control the spread of pests in the farm.
The question is incomplete but I will help you the much I can. We know that organisms that have favorable traits live long enough to reproduce and pass on these favorable traits to the next generation. Therefore, the insect with the pesticide resistance gene reproduces. Because these insects are more likely to survive pesticide application, insects with this trait become more prominent in the population
