Answer:

c. DNA

Explanation:

DNA is the molecule which has instructions in the form of nucleotides to form mRNA. Synthesis of mRNA is primarily required so that protein could be synthesized. Before protein could be synthesized, some mRNA molecules like mRNA, tRNA and rRNA are synthesized by using one of the DNA strands as a template and subsequently these mRNAs collectively lead to the synthesis of proteins. The synthesis of RNAs from DNA molecule is known as transcription while synthesis of proteins with the help of RNAs is known as translation.

What do you think selectively permeable means?
enot [183]

Answer:

B. The membrane lets certain substances move across it freely, while others must move through a “gate”.

Explanation:

Selective permeability is a property of cellular membranes that only allows certain molecules to enter or exit the cell. This is important for the cell to maintain its internal order irrespective of the changes to the environment. For example, water, ions, glucose and carbon dioxide may need to be imported or exported from the cell depending on its metabolic activity. Similarly, signaling molecules may need to enter the cell and proteins may need to be released into the extracellular matrix. The presence of a selectively permeable membrane allows the cell to exercise control over the quantum, timing and rate of movement of these molecules.

Un tractor tira de un remolque cargado sobre un camino plano libre de fricción, con una fuerza horizontal constante de 440 N. Si
Bogdan [553]

Answer:

1,6 m / s ^ 2

Explanation:

De las leyes de Newton;

Fuerza = masa × aceleración

masa = 275 kg

Fuerza = 440 N

Aceleración = Fuerza / masa

Aceleración = 440N / 275Kg

Aceleración = 1,6 m / s ^ 2
