The cycle of the moon circling the earth is _________
Answer:
The Moon circles the Earth once every 27.3 days – each sidereal month – but its phases repeat every 29.5 days – each synodic month. The difference arises because the Earth itself moves around the Sun by a distance of around thirty degrees each month.

Answer:
The higher the density, the more closely packed the particles called atoms and molecules. The lower the density the more spaced muy the particles are
If density = mass divided by volume, than the more volume a material has the less dense it is. For example, if there are five people in a room that is 5ft. by 5ft. the people will be tightly packed together and more dense. If those same five people were in a room that is 20ft. by 20ft. they would have more space and it would not be as dense in the room.

Which statement is true about a nucleus? a It is surrounded by a membrane. b It is the site of enzyme storage. c It is surrounded by the nucleolus. d It is the site of energy conversion.
Answer:
Option D
Explanation:
The well defined nucleus is absent in prokaryotes whereas the well defined nucleus covered with nuclear envelope is present in eukaryotes. The site of replication and transcription is the nucleus in the living organism.
The nucleus contains the double membrane structure. Outer membrane and inner membrane covers the nucleus. Nucleus also contains the nuclear pore through which molecules can move inside and outside of the nucleus and the cytoplasm.

Sam does an experiment in his lab. He discovers that the mass of the reactants before his
experiment is the same as the mass of the products after his experiment. What did he prove?
Answer:
The law of conservation of mass
Explanation:
In the given scenario of the experiment, Sam is proving here the law of conservation of mass.
What is law of mass conservation?The law of conservation of mass basically implies that mass can neither be created nor be destroyed in any chemical reaction.
When coal is burned, for instance, the carbon atom altered into carbon dioxide. The carbon atom changes from a solid to a gas, but its mass remains constant.
The law of conservation of mass is a fundamental physics principle. In other words, no matter how the parts are rearranged, the mass of an object or collection of objects remains constant.
The law of conservation of mass was critical to the advancement of chemistry because it helped scientists understand that substances did not vanish as a result of a reaction, but rather transformed into another substance of equal mass.
Thus, here Sam is demonstrating law of mass conservation.

Explanation:
which best describes a gene?
Answer:
Asegment of chromosomal DNA
Explanation:
A gene is a hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes. It is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person's unique physical features.

Proteins are synthesized based on genetic information carried by DNA. Explain how the structure of DNA is important in the synthesis of different kinds of proteins. In your explanation, include a description of the two main processes involved in protein synthesis.
Answer:
One of the single most significant biological processes that individual cells are capable of would be building their specific proteins. This process is referred to as protein synthesis. DNA (deoxyribonucleic acid) and RNA (ribonucleic acids) are involved in protein synthesis, which occurs in the given cell's nucleus. The DNA has a unique structure vital for distinct enzymes to unwind in a specific section of DNA. This, in turn, makes that section accessible for an RNA copy to be made. Once made, the RNA molecule moves from the given cell's nucleus to its cytoplasm, where, finally, the actual protein synthesis process can occur.
Explanation:
took me awhile to research this
Proteins are synthesized by the DNA through the processes of the central dogma. Proteins are essential for cell growth, functioning, structural arrangement etc.
DNA is a double-stranded nucleic acid that contains genetic codes and information. DNA replicates to form two daughter cells by the process of replication.
The duplicated DNA serves as a template for the construction of RNA by the process of transcription. The unique double helix of deoxyribonucleic acid makes it accessible for the formation of mRNA.
The single-strand RNA have nucleotide bases that code for the amino acids with the help of tRNA and ribosomes by the process of translation.
The amino acids produced bonded together to create proteins.

What happens when magma cools during the rock cycle? Igneous rock is formed. Metamorphic rock is melted. Sediments form sedimentary rock. Metamorphic rock forms sediments.
Answer: igneous rock is formed
Explanation:
When magma cools down during the rock cycle then igneous rock is formed. Thus, the correct option is A.
What are Igneous rocks?Igneous rock is one of the three main rock types, while the other being sedimentary and metamorphic rocks. Igneous rocks are the rocks formed through the cooling and solidification of magma or lava from volcano. The magma can be derived from partial melts of existing rocks in either a planet's mantle or the crust.
Lava from the volcano cools to form volcanic rock as well as volcanic glass. This magma can also extrude into Earth's atmosphere as part of a violent volcanic explosion. This magma then solidifies in the atmosphere to form volcanic rock called as tephra. In the atmosphere, tephra is more often called as volcanic ash.
Therefore, the correct option is A.
