If a hot liquid is poured into a cup, the cup will soon feel warm. How does the increase in temperature change the particles that make up the cup?
Answer:
Adding energy (heating) atoms and molecules increases their motion, resulting in an increase in temperature.
Removing energy (cooling) atoms and molecules decreases their motion, resulting in a decrease in temperature.
Energy can be added or removed from a substance through a process called conduction.
In conduction, faster-moving molecules contact slower-moving molecules and transfer energy to them.
During conduction the slower-moving molecules speed up and the faster-moving molecules slow down.
Temperature is a measure of the average kinetic energy of the atoms or molecules of a substance.
Heat is the transfer of energy from a substance at a higher temperature to a substance at a lower temperature.
Some materials are better conductors of heat than others.

What is a natural way to control an aphid population?
release ladybugs into habitat
praying mantis
insecticide
Answer:
I would say that the answer is A, or releasing ladybugs into a habitat.
Explanation:
This is the only "natural" way to control an aphid population. However, please note that as well as ladybugs, praying mantis's also eat aphids. But, the answer choice doesn't describe the option very well, so that is why I say that it is A.
Hope it helps!
The natural way to control an aphid population is release ladybugs into habitat. The correct option is 1.
What is Ladybug?Ladybugs are natural aphid predators that can consume large numbers of them, assisting in population control without the use of harmful chemicals.
A natural way to control an aphid population is to release ladybugs into the aphid's habitat.
Although praying mantises are natural predators of aphids, they are less effective at controlling their population than ladybugs.
Insecticides, on the other hand, are chemical treatments that can be harmful to both beneficial insects and the environment.
As a result, using insecticides to control aphid populations is not a preferred method, particularly in natural or organic settings.
Thus, the correct option is 1.

In 1-2 sentences, explain why mutations can be beneficial to an organism.
Answer:
Some mutations can change genetic variation in a way where an organism can adapt to the surrounding environment. Mutations created gills, which allow fish to breath underwater. Mutations allowed giraffes to reach leaves higher up on trees so they can get food. Mutations also allowed humans to be able to adapt to any environment and situation and continue growing.
Explanation: Brainliest is always appreciated
Mutations are random changes in the DNA sequence of an organism's genome. Mutations can be beneficial to an organism because they can lead to genetic variation, which can allow for natural selection to occur.
What is mutation?Mutation is a process that refers to a change in the genetic material (DNA) of an organism. The genetic material carries the information that determines an organism's characteristics and traits, like eye color, hair color, or susceptibility to certain diseases. Mutations can happen naturally, or they can be induced by various factors such as exposure to radiation, chemicals, or viruses.
Mutations can affect a single base pair of DNA, a larger segment of DNA, or an entire chromosome. They can be classified in many ways, but one of the most common ways is by their effect on the genetic material.

Answer:
D
B
A
A
Explanation:
I hope this helps :)
Answer:
1 - D
2 - B
3 - A
4 - A
Explanation:
Hello There!
D=Distance
T=Time
S=Speed
For the first one we are given the speed and the time and we need to find the distance
To do so we multiply the two together( the two meaning the speed and the time)
They run 20 m per second and
if they run for 40 second
(20*40=800)
they will run for a total of 800m therefore the answer to the first one is D
for the second one we are given the distance and the time and we need to find the speed.
Looking at the formula chart we can find the speed by dividing the distance over the time
so speed = 80/5
80/5=16 so the speed is 16m/s (B)
For the third one we are given the distance and the time and we need to find the speed
Once again we can find the speed by dividing the distance over time
20/5=4 so the bunny hops 4m/s
For the last one we are given the speed and the distance and we need to find the time it took to get to the associated distance
another way we can find the time is by dividing the given speed by the distance
so time = 1500/250
1500/250=6 so it will take the space ship 6 seconds to reach a distance of 1500m
What statement about childhood obesity is true?
Obesity can lead to high blood pressure.
Obesity is another word for being overweight.
Obesity is not curable.
Obesity leads to low cholesterol.
Answer:
Obesity can lead to high blood pressure.
Childhood obesity is a severe public health concern that is spreading across the country. Body mass index (BMI) at or above the 95th percentile for kids of the same age and sex is what is referred to as having it. The claims are all accurate.
Obesity can raise the chance of having high blood pressure because it alters the body in ways that enhance that risk. This includes increased blood fat levels, hormonal changes, and an increase in the creation of proteins that can narrow the blood arteries.
Overweight is sometimes referred to as obesity. Body mass index (BMI) at or above the 95th percentile for children is the criterion for this condition.
