Answer:
Fish are gill-bearing aquatic craniate animals that lack limbs with digits. They form a sister group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups.
Explanation:
Bats and birds are unrelated animals, yet they both evolved wings. by acquiring similar traits (i.e., wings) as they adapted to similar environments, these species exhibit convergent evolution through analogy present between the wings. Convergent evolution happens when two distantly related organisms acquire the similar traits in response to the similar habitat or niche.
Precipitation is the primary source of water stored in an aquifer. the correct option in regards to the given question is the first option.
An aquifer is actually an underground layer of water that
contains permeable rocks, gravel, sand etc. the water can be brought to the
surface by making a water well. Hydrogeology is the study of aquifers and the
way of water flow in the aquifers. The depth of the aquifers differs from area
to area and the aquifers that are closest to the surface are used for drinking
and irrigation purposes.
Answer:
The movement of glucose across the cell membrane through facilitated diffusion one of the form of passive transport because it does not require the energy to transport the glucose molecule across the cell membrane and the transport is along the concentration gradient.
In facilitated diffusion the passage of molecules if facilitated by a carrier protein or a channel protein. The rate of transport of molecules in facilitated diffusion is greater than simple diffusion.
Through facilitated diffusion, some polar and charged molecules can cross the cell membrane without the expense of energy.
