Answer:
Explanation:
1.Hot coffee is stirred with a spoon, the spoon gets hot due to _______________.conduction
2.The fireplace has a glass screen. The side of the chair facing the fireplace gets warm because of_______________. Radiation
3. A certain type of decorative lamp contains colored liquids. These liquids form globs that break off and rise to the top of the liquid. The globs rise due to _______________.Convection
hope this helps
Answer:
1) Conduction.
Heat transfers to a spoon as the heat energy is passed from the coffee to the spoon through conduction.
2) Radiation
The heat on the glass surface gets radiated into the chair which causes the chair to warm up.
3) Convection
The globs are hot and less dense, which rises to the top whereas the cold globs are more dense which causes it to settle down.

How many atoms in all are in a molecule of serotonin?
Answer:
10 carbon (black), 12 hydrogen atoms (white), 2 nitrogen atoms (blue), 1 oxygen atom (red)
Explanation: Serotonin is a molecole composed of all of these atoms
A molecule of serotonin has 25 atoms in total, and these atoms are arranged in a specific pattern to give serotonin its unique chemical and biological properties.
What is serotonin?Serotonin is a neurotransmitter, which means it is a chemical that is used by the nervous system to transmit signals between nerve cells. It is also a hormone that regulates various physiological processes in the body. The chemical formula for serotonin is [tex]C_1_0H_1_2N_2O,[/tex] which indicates that it contains 10 carbon atoms, 12 hydrogen atoms, 2 nitrogen atoms, and 1 oxygen atom. The molecule of serotonin consists of a benzene ring with two substituents: an amino group and a hydroxyl group (-OH). The amino group and hydroxyl group are attached to adjacent carbon atoms in the benzene ring, and the nitrogen atom is attached to one of the carbon atoms in the amino group.
Hence, a molecule of serotonin has 25 atoms in total, and these atoms are arranged in a specific pattern to give serotonin its unique chemical and biological properties.

A biologist collects DNA samples from two sisters. The younger sister has blond hair. The older sister has red hair. The sisters have different traits because their DNA contains different —
A---order of nucleotides
B---types of sugar molecules
C---sized phosphate groups
D---types of nitrogenous bases
PLZ ANSWER IF U ARE ONLY SMART AT THIS STUFF
The sisters have different traits because their DNA contains different ORDER OF NUCLEOTIDES (Option A).
DNA is a double helix composed of two long chains of nucleotides.
In DNA, there are four types of nucleotides, each containing one different nitrogenous base, i.e., Adenine, Guanine, Thymine and Cytosine.
During gene transcription, a fragment of DNA called gene is used as template to create an mRNA, which is in turn used as template to create a protein.
The order of nucleotides in a given gene sequence determines the sequence in mRNA and ultimately also the protein sequence that's synthesized from this sequence.
In conclusion, the sisters have different traits because their DNA contains different ORDER OF NUCLEOTIDES (Option A).

The speed at which waves approach the shore depends on the shoreline features and the depth of the sea floor. When a wave reaches the shore, it releases a burst of energy that generates a current which runs parallel to the shoreline. What is this current called?
Answer:
Longshore current.
Explanation:
A wave is a disturbance which travels through a material medium without any permanent displacement of the particles of the medium. During the propagation of a wave, energy is transmitted from one point to another since waves flow with energy. The higher its speed of propagation, the higher the energy of the wave.
The energy released by the wave at shore produces a current which is referred to as a longshore current.
Answer:
It would be Longshore Current

Are there any mammalian cells that would be a good source for dividing cells? What types of cells would most like NOT have cells undergoing division?
Answer:
Skin cells, bone cells
Explanation:
1. Skin cells are constantly being replaced, so it's likely they will be undergoing Mitosis.
2. Bones grow very slowly, and can last for years, which means that it's unlikely they will be undergoing mitosis.
There are a couple of mammalian cells that would be a good source for dividing cells. They include but not limited to:
The cells of the skinCells in the bone marrowThe cells of the skin adjacent to the environment are constantly being replaced by cell division due to death relating to environmental factors.
The cells in the bone marrow are also dividing constantly because old blood cells are constantly being replaced.
Some cells in the human body do not divide ordinarily, unless they are called upon to do so on special circumstances. For example, the cells of the heart stop dividing once the heart gets to a particular size. The cells enter the quiescent stage of the cell cycle and they are only called upon to divide in case an injury occur to the heart and it needs to repair itself.

Hope I helped
Explanation: i watched like 20 times
Answer:
Consume already dead meat - when Scar brings the Hyena food because that food is already dead.
Kill and Consume young, sick, or small animals - When one of the Hyenas wants to eat one of the smaller or sick animals at the Stampede scene.
A pack kills larger weakened animals - I guess that could be when Scar kills Mufasa because he is already weakened or when the Vultures are trying to eat Simba because he is tired and weak from walking.

Which of the following would not be considered an observation in terms of the scientific method? A. tasting a pasta sauce after adding a new ingredient B. looking at a blood sample through a microscope C. a dog buries a bone in the backyard D.listening to bats of different materials hitting a baseball
Answer:
C. a dog buries a bone in the backyard
Explanation:
A dog burying a bone in the backyard is not an observation in terms of scientific methods.
Observation is the process of acquiring data about a phenomenon under study.
Most times, senses are used in making observations. Our sense of taste, hearing, sight etc. comes handy when making observation.
Also, we can use some specialized equipment to make observations.
A dog burying a bone in the backyard is not an observation. None of the senses nor instruments are used to gather any relevant information.Relationships of selected organisms based on a catalase structure which of the following student claima is best supported by the data provided

The atomic number of carbon is six, which means that a carbon atom has six protons. Carbon has three naturally occurring isotopes: carbon-12, carbon-13, and carbon-14. Which of these statements are true about carbon and its isotopes? Select all that apply.
A. All carbon atoms have six neutrons.
B. All carbon atoms have six protons and six electrons.
C. Atoms of all carbon isotopes have either more than 6 electrons or fewer than 6 electrons.
D. Atoms of some naturally occurring carbon isotopes may have six neutrons.
E. Atoms of some naturally occurring carbon isotopes may have twelve neutrons.
Answer:
B and D
Explanation:
Since it says all carbon atoms have six electrons, we know that they only have six protons too. The carbon 13 and 14 means they have extra neutrons that increases their atomic mass.
