Which elements are part of an area's topography? Check all that apply.
atroni [7]

Answer: elevation,  landforms , relief

Explanation:

Area's topography can be defined as the physical features with which the area of the land is associated with. These features are mountains, lakes, valleys and rivers.

The following are the elements of the parts of the area's topography:

Elevation: The elevation describes the height above the given level. This can be used to measure the height of the mountain.

Landforms: Landforms are the features of the Earth's surface that includes the parts like hills, plains and mountains.

Relief: A relief gives an idea of elevation from the concerned point in a landform.

Explain if an unknown substance found on a meteorite is determined to contain no trace of carbon, can scientists conclude that t
Svetach [21]
All life as we know it is carbon-based, so what scientists could determine is that there is no carbon-based life at the origin of the meteorite. However, this does not necessarily mean that there is no life there; our knowledge is only based on our experiences of life on Earth, so it is possible that life has developed in other regions of space upon other elements and formations. For example, there could be life based on silicon or other chemical compositions.

What two processes must take place in order to go from a gene to a protein?
yanalaym [24]

Most genes contain the information needed to make functional molecules called proteins. (A few genes produce other molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression.

During the process of transcription, the information stored in a gene's DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus. Both RNA and DNA are made up of a chain of nucleotide bases, but they have slightly different chemical properties. The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.

Translation, the second step in getting from a gene to a protein, takes place in the cytoplasm. The mRNA interacts with a specialized complex called a ribosome, which "reads" the sequence of mRNA bases. Each sequence of three bases, called a codon, usually codes for one particular amino acid. (Amino acids are the building blocks of proteins.) A type of RNA called transfer RNA (tRNA) assembles the protein, one amino acid at a time. Protein assembly continues until the ribosome encounters a “stop” codon (a sequence of three bases that does not code for an amino acid).

The flow of information from DNA to RNA to proteins is one of the fundamental principles of molecular biology. It is so important that it is sometimes called the “central dogma.”

Through the processes of transcription and translation, information from genes is used to make proteins.

What happens to energy that is released from food, but not captured and store into<br> ATP?
nignag [31]

Answer:

In conditions of low or no oxygen the process of anaerobic respiration occurs. The 'an' in 'anaerobic' means without. During anaerobic respiration, the oxidation of glucose is incomplete - not all of the energy can be released from the glucose molecule as it is only partially broken down.
