Answer:

The correct option is A) Active transport moves substances against the concentration gradient.

Explanation:

Facilitated diffusion can be described as the type of diffusion which occurs with the help of other molecules. For example, when integral proteins help in the transport of a molecule through the cell membrane. Facilitated diffusion is a type of passive transport as it allows molecules to move from an area of higher concentration to an area of lower concentration along a concentration gradient.

Active transport is the movement of molecules against the concentration gradient from an area of lower concentration to the area of higher concentration and hence, require energy.

Why are architects and engineers concerned about surface waves

Ainat [17]

Answer:

Because they are the most destruction waves

Explanation:

Surface waves travel just below the earth’s surface. Examples of surface waves are Rayleighs and Long waves. Rayleighs cause ripples on the ground while long waves move the ground horizontally perpendicular to the direction of travel of the wave. Therefore, these waves are capable of destroying the foundations of structures and hence causing their collapse. Studying these waves allow these professionals to design foundations strong enough to withstand these waves.

dmitriy555 [2]

Answer:

The correct option is D. The chemical bond breaks between the second and third phosphate groups.

Explanation:

Adenosine phosphate (ATP) can be described as main energy-carrying molecules which are required by each cell to carry out its normal functions.

A molecule of ATP comprises of the nitrogenous base Adenine, pentose sugar ribose and three molecules of phosphate.

The bond between the second and third molecule carries high amounts of energy. When this bond is broken, huge amounts of energy is released which is used by the cells to carry out essential processes.

o-na [289]

A sugar-phosphate backbone (alternating grey-dark grey) joins together nucleotides in a DNA sequence. The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.The two strands run in opposite directions, one going in a 3' to 5' direction and the other going in a 5' to 3' direction. The nitrogenous bases are positioned inside the helix structure like "rungs on a ladder," due to the hydrophobic effect, and stabilized by hydrogen bonding. Uracil is one of the four nucleobases in the nucleic acid of RNA that are represented by the letters A, G, C and U. The others are adenine, cytosine, and guanine. In RNA, uracil binds to adenine via two hydrogen bonds. In DNA, the uracil nucleobase is replaced by thymine. Uracil is a demethylated form of thymine.
