Which of the following statements regarding membrane transport proteins is NOT true? Facilitated transport is required to move any molecule against its concentration gradient. Both transporter proteins and ATP-powered pumps represent active transport. Uniporter transport is fast, reversible, and highly specific. Uniporters move ions faster through membranes than do ion channels.

Uniporters me be ions faster through membranes than do ion channels

Explanation:

Membrane transport protein is a membrane protein that help to function in moving ions, small molecules and macromolecules across a biological membrane.The proteins may assist in the movement of substances by facilitated diffusion or active transport.

Uniporters are membrane transport protein that move one species of substrate across the cell membrane.ion channels move ions faster than uniporters membrane because they are pore forming membrane that allow ions to pass it's pore freely.

brain development. a child's brain undergoes an amazing period of development from birth to three—producing more than a million neural connections each second. the development of the brain is influenced by many factors, including a child's relationships, experiences and environment.

explanation:

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
