Answer:

Explanation:Cell membranes act as barriers to most, but not all, molecules. Development of a cell membrane that could allow some materials to pass while constraining the movement of other molecules was a major step in the evolution of the cell. Cell membranes are differentially (or semi-) permeable barriers separating the inner cellular environment from the outer cellular (or external) environment.

Water potential is the tendency of water to move from an area of higher concentration to one of lower concentration. Energy exists in two forms: potential and kinetic. Water molecules move according to differences in potential energy between where they are and where they are going. Gravity and pressure are two enabling forces for this movement. These forces also operate in the hydrologic (water) cycle. Remember in the hydrologic cycle that water runs downhill (likewise it falls from the sky, to get into the sky it must be acted on by the sun and evaporated, thus needing energy input to power the cycle)

When thinking of the functions of the organelles.which cell tissue in the human body would have the most mitochondria and why

Anni [7]

Answer:

Muscle cells, especially heart muscle cells and fat cells have the most mitochondria in the human body.

Explanation:

Mitochondria, the powerhouse of the cell is an organelle where cellular respiration occurs. They supply energy to the cells for their functioning. The number of mitochondria in a cell vary depending on the energy requirement of that cell.

Muscle cells are very active in our body and need energy for the movement. Heart muscle cells require a lot of energy to contract and pump blood through the circulatory system all the time. So they have a lot of mitochondria to produce a vast amount of energy they need.

Which best describes why active transport requires atp to move molecules across the cell membrane?

scoray [572]

Answer:

B. Molecules are moved against the concentration gradient.

Explanation:

Due to the higher concentration of the molecules of one of the sides than the other,in order to move molecules from the side with higher concentration of molecules to the side of lower concentration of molecules which is against the movement of molecules across the membrane, energy must be applied i.e atp.

Why is the structure of dna important to its function

aleksandr82 [10.1K]

Answer:

The function of DNA is tied to its structure. ... The sugars and phosphates link the nucleotides together to form each strand of DNA. When two strands of DNA come together, base pairs form between the nucleotides of each strand. Nitrogenous bases pair together in the following way: A-T and C-G.
