What are the 3 common characteristics of planets? Describe one of the characteristics of one of the planets in our solar system
Answer:
The solar system is host to two broad categories of planets. The four closest to the sun — Mercury, Venus, Earth and Mars — are the terrestrial planets. They have rocky surfaces enclosed by relatively shallow atmospheres. The gas and ice giants — Jupiter, Saturn, Uranus and Neptune — are outliers. They are much larger than the terrestrial planets, but their cores are small and icy. Most of their size is formed by a combination of gases that become denser and hotter as you get closer to the core. Scientists count eight planets overall. Pluto was reclassified as a dwarf planet in 2006.
Explanation:
To answer to which of the following questions would be most useful in determining whether to classify an organism in kingdom Plantae or kingdom Animalia
A. is the organism able to respond to stimuli
B. Is the organism able to make its own food
C. Is the organism unicellular or multicellular
D. Is the organism made of cells with or without nucleus
Answer:
A. is the organism able to respond to stimuli
Explanation:
The determination of whether to classify an organism in kingdom Plantae or kingdom Animalia is the organism able to make its own food or not. Thus, the correct option is B.
What are the differences between plants and animals?The main defining characteristics between the organisms of Kingdom Plantae include all the multicellular, photosynthetic eukaryotes category. Plants belong to the kingdom Plantae. Plants are the primary producers of the Earth’s ecosystem. They can prepare their own food (carbohydrates).
The characteristics of the Kingdom Animalia include the organisms which belong to the category of multicellular, eukaryotes. They are classified into various classes such as mammals, amphibians, reptiles, fish, birds, and insects. They cannot prepare their own food. They can move from one location to the other location.
Therefore, the correct option is B.

Priscilla was building a circuit that used copper wires to connect a battery to a light bulb. As she connected the final wire from the light bulb back to the battery, the light bulb turned on. Priscilla knew that current was now flowing through her closed circuit. What makes the current in the circuit flow?
Answer:
The complete path provided by the closed circuit enables electric current produced by the battery to flow round the circuit
Explanation:
Electric current consists of charges (electrons) in motion from one region to another.
An electrical circuit is any closed path through which electric current can flow.
An electrical circuit consists of an energy source that supplies the electrons moving, a path along which the electrons can travel, and a load or appliance that uses the electrical energy. When the circuit is broken at any point, electrons will cease to flow since there is no complete path for it to flow. Such a circuit is known as an open circuit.
In the circuit built by Priscilla, the battery serves as a source of energy by providing the electrons that moves round the circuit. The wires provides the path for electrons to flow from the battery through the light bulb and back to the battery. When she connected the final wire from the bulb back to the battery, the circuit becomes complete/closed and current then flows to light up the bulb.
While looking at a cell under a microscope, a scientist is able to see a biological molecule.

Based on the information, what conclusion can the scientist draw regarding this nuclei acid?
A. the nuclei acid is DNA and would be found in the cytoplasm.
B. the nuclei acid is DNA and would be found in the cells membrane.

Cells use a molecule called (DNA / RNA / ATP / CMP) to store and release energy like a battery. The energy is stored in chemical bonds between (nucleotide / oxygen / phosphate / ribose) groups of the molecule, and the energy is released when the chemical bonds are broken.
Answer:
Cells use a molecule called ATP to store and release energy like a battery. The energy is stored in chemical bonds between phosphate groups of the molecule, and the energy is released when the chemical bonds are broken.
Explanation:
The Adenosine Triphosphate (ATP) is a molecule made of adenine, ribose, and three phosphate groups, which are the ones that store the energy in its bounds. The ATP is the molecule that provides the energy to the different processes that happen in a cell. The molecule is made from the glycogen, fats, and carbohydrates that the body has absorbed in the intestines. When the body needs energy, the ATP loses one or two phosphates, becoming ADP and AMP. When the phosphorylation happens, which is the loss of phosphate, the energy is released.
Spontaneous generation is the idea that new living organisms can form from nonliving matter. Cell theory, however, states that cells

OC. A container of soup that was heated and sealed did not grow mold even after several months.
OD. A mold sample examined under a microscope showed a regular structure made of many individual cells.
Answer: C. A container of soup that was heated and sealed did not grow mold even after several months.
Explanation:
Explain the cause-effect relationship between environmental changes and the extinction of species.
Answer: Anything living needs to have certain conditions, if for example a group of flightless birds who are adapted for warm weather had their environment get colder each year and more extreme the surrounding plants and other animals may have a difficult time surviving and this will cause the birds to have less food. The birds also will not be accustomed to these changes and will not be able to adapt their bodies fast enough. This also makes reproduction difficult and in turn further dwindles the population.

Explanation:
Determine the amino acid chain that would result from the sequence AUG-CCC-GGA-UUA-UAG.
Answer:
methionine-proline-glycine-leucine-stop
Explanation:
Using an amino acids chart, you can line up the 3 bases in each section to find the protein chain that corresponds. The stop at the end marks the end of protein synthesis, which ends the sequence.
The compound comprising carboxylic and amino groups is called amino acids. They are vital for the formation of proteins in the cells.
Sequences are read in the three pairs of codons in the form of triplets to form a form an amino acids sequence.
The amino acid sequence that will be formed from the given sequence AUG-CCC-GGA-UUA-UAG will be:
methionine-proline-glycine-leucine-amber
AUG is the start codon which also codes for the amino acid methionine.CCC codes for the amino acid proline and its one-letter code will be P.GGA is glycine and is abbreviated as G.UUA codes for leucine and is represented by U.UAG is the amber or the stop codon which is responsible for terminating the sequence.Therefore, Met-Pro- Gly- Leu- Amber is the amino acid sequence.

Scientists took some cells and grew them in a Petri dish with nutrients. After a while, the cells grew to form a thin layer and stopped when they came in contact with other cells. What does this tell you about cells and the cell cycle?
Answer:
Contact inhibition.
Explanation:
Contact inhibition is a response of a cell in which cell growth stopped when it touches or comes in contact with another cell. When the normal and healthy cells grows and touching other cells, the cell receives a red light signal to stop its growth so the cell stop its growth while on the other hand, if there is no contact with other cell the cell continues its growth.

Explanation:
Which conclusion is supported by this evidence? Neither ball has a charge. The balls are both positively charged. One ball is positively charged, and the other is negatively charged. Each ball has a charge, but the type of charge is unknown.
Answer:
The correct answer is - Neither ball has a charge
Explanation:
If the two balls are hanged near one another without touch or an external charge to any of the balls there would be no charge present. In the given question is it given that two balls hang down without any contact in them.
So there is no possible way to generate charge and remain uncharge in their position till they get any external charge.
The correct answer is - Neither ball has a charge
