Compared to the inertia of a 1-kilogram mass, the
avanturin [10]

Answer:

D. 4 times as great

Explanation:

The inertia of an object is the resistance offered by the object to change in its motion or position.

Then concept of inertia is obtained from Newton's first law of motion which states that an object which is not subjected to any net external force will remain its position of rest or constant velocity of motion until some net external force acts on it. The object at rest will then start to move whereas the object moving at constant velocity will experience a change in its speed or direction of motion.

This reluctance to change position is greater, the more massive an object is as well as the higher the speed of motion of the object. Thus, inertia is directly proportional to the mass of the object as well to the velocity of an object in motion.

From Newton's first law, inertia can be calculated as the force to be overcome to mobile an object, i.e. Inertia = F = ma

Where m is mass of object, a = acceleration of the object.

Objects on the earth's surface experience a constant acceleration, g.

Thus for a 1 kg mass, Inertia = 1 × g

For a 4 kg mass, inertia = 4 × g

The inertia of a 4 kg mass is four times as great as a 1 kg mass.

Describe the relationships among amino acids, chromosomes, proteins, and genes in the cells of a jackalberry plant. Make sure to
nasty-shy [4]

Answer:

The jackalberry plant is a multicellular organism whose cells contain chromosomes. The chromosomes contain genes that are transcribed to produce messenger RNAs, which are then translated into proteins  

Explanation:

The Jackalberry tree is a plant, i.e., a multicellular organism. Multicellular organisms have chromosomes in the nucleus of each cell. A chromosome is a long DNA molecule that contains part (or even all) of the genetic information of a particular organism. Genes are specific segments of the chromosomes, which are expressed in a process called 'transcription' where a gene is used as template to synthesize an RNA molecule, usually a messenger RNA (mRNA). Subsequently, these mRNAs are used to synthesize proteins by a process called 'translation'. In an mRNA molecule, each specific triplet of nucleotides is known as a codon and corresponds with a specific amino acid during protein synthesis. Thus, the mRNA sequence dictates the correct order of amino acids (i.e., the building blocks of proteins) in the polypeptide chain.
