The atoms and molecules that make up substances are always in motion. What happens when heat or thermal energy is added to a substance?
the particles move faster
the particle movement doesn't change
the particles move slower
the particles stop moving
Answers
Answer:
the particles move faster
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
Answer:
the particles move faster
Explanation:
When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises.

Write one paragraph about Tilikum the Orca's life in SeaWorld.
Answers
During his life, Tilikum, the largest orca in captivity, weighed 12,500 pounds and measured over 22 feet in length. Tilikum was captured near Iceland in November of 1983, over 30 years ago. At only 2 years old, when he was approximately 13 feet long, he was torn away from his family and ocean home.
A class is learning about the evaporation step in the water cycle using a simple model. The model consists of a 1-L container of water. When the container is open, and it receives sunlight, the water can freely evaporate from the container. The students design an experiment using the model. In the experiment, the container will be filled and left open outside from dawn until dusk at different times of the year. The students will run the experiment only on days with clear weather. As a basis of their experiment, the students make an assumption that more water will evaporate from their model when more solar energy is present. Which of the following is a result that the students could predict in order to test their assumption?
A.
Equal amounts of the water will evaporate on summer days and winter days.
B.
Less of the water will remain in the container after one day in summer than after one day in winter.
C.
Less of the water will remain in the container after one day in winter than after one day in summer.
D.
Some of the water will evaporate on winter days but not on summer days.

Answers
Answer:
Protons are found in the: nucleus
The number of protons determines: the identity of the atom/the element
The number of protons is called: the atomic number
Where you look to find the number of protons: periodic table(ex. boron is 5, barium 56, actinium 89, neon 10)
Protons are charged: positive charge
Neutrons are found in the: nucleus
Neutrons are charged: neutral(no charge)
They help protons by: stabilizing their repulsive charge(same charge repels) and stabilizing the nucleus
The mass of protons and neutrons are: 1 amu
Electrons mass is: 5.45 × 10^-4 amu(usually for practical purposes people just say it has 0 mass)
Electrons are charged: negatively
In a neutral atom: number of protons = number of electrons(net charge = 0)
Electrons are responsible for: keeping the atoms neutral, valence electrons interact with other atoms to form ionic compounds.

BRAINLIEST+15 PTS-What does it mean when a plant is "pure for its trait'?
Answers
Answer:
Non-N-fixing plants usually benefit from reduced competition in mixed stands compared to pure stands and attain higher biomass and N content per plant
Explanation:
a plant that has a pure trait is homozygous. homozygous traits are either a combination of two dominant alleles or the two recessive alleles. a hybrid would be the opposite, consisting of dominant and recessive alleles, therefore making it unpure (lol sorry) and hybrid.

The science club at Tracy's school is researching how temperature affects fish reproduction. They conducted a study to find out if raising the water temperature would decrease the number of bass eggs that hatched.
They gathered bass eggs from a local lake. Half of the aquariums were kept at room temerpature, and the other half were placed in a sunny window.
What is the independent (test) variable from this experiment?
The size of the lake.
The number of bass eggs that hatch.
The temperature of the water.
The number of aquariums.
Answers
Answer:
The temperature of the water.

Index fossils help scientists estimate the age of a rock because index fossil species only existed for a relatively short time. What happened to the species that are now used as index fossils.
1. They became extinct
2.They changed diets
3.They hid in marine sediments
4.They migrated to new environments
Answers
Answer:
They became extinct.
Explanation:
The text says that index fossil species only existed for a relatively short time. If they don't exist anymore, that means that they are extinct.
1. They became extinct
they became extinct and lived for a distinct period of time which means that and sediment/ fossils found alongside these index fossils would be from the same time period

What is a blood genotype?
A blood genotype is the genetic makeup of the blood of a person.
Given that one parent is o and the other is a.
Type A = AA (homozygous dominant) or Ao (heterozygous Ao)
Type O = oo (homozygous recessive)
So if AA × oo = 100% Ao (type A)
If Ao × oo = 50% Ao (type A)
and 50% oo (Type O)
The standard table is attached of the cross between A and O.
So either all children will be total A genotype or half A and half O.
Thus, the prediction of the blood genotypes is total A genotype or half A and half O.

Answer:
Duodenum (option 3)
Explanation:
Digestion of carbohydrates, proteins, and fats continues in the small intestine. Starch and glycogen are broken down into maltose by small intestine enzymes. Proteases are enzymes secreted by the pancreas that continue the breakdown of protein into small peptide fragments and amino acids.
The duodenum is the first section of the small intestine and is the shortest part of the small intestine. It is where most chemical digestion using enzymes takes place

vacation.
They will select different types of seeds, such as beans, peas, or sunflower seeds.
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 pots.
They should observe and document the changes that occur over time, including the
emergence of roots and shoots.

The seed germination investigation during the students' summer vacation involves selecting various seeds (e.g., beans, peas, sunflower) and setting up an experiment. They will place the seeds in different conditions, like light vs. dark or wet vs. dry, and pot the same seed in multiple pots. Throughout the investigation, the students are expected to carefully observe and document the changes that take place over time, including the growth of roots and shoots. This hands-on approach allows them to gain practical knowledge of seed germination and develop essential scientific skills in observation, data collection, and documentation.
