The correct answer is skeletal development resulting in the movement of amphibians onto land and possibly evolved from lobe-finned fishes.
The initial lobe-finned fishes are bony fish with lobed, fleshy, paired fins that are connected with the body by a solitary bone. The fins of the lobe-finned fishes vary from those of all other fish in that each is borne on a lobe like, fleshy, scaly stalk protruding from the body.
This skeletal development will show that the species first developed in water and then gradually move onto the land and ultimately developed as species of land.
Answer:
two, phospholipids, non polar, tails, polar, heads.
Explanation:
This is just basically illustrating one of the components of the lipid bilayer memebrane. The membrane is made up of two lipid layers with the polar head groups facing either the cytosol or the outer surroundings while the non polar tails facing each other. Such that this bilayer act as a barrier between the cytosol of the cell/organelle eg endoplasmic reticulum and the outer surroundings.
Answer:
rhizobia is an important nitrogen fixing bacteria found in the soil to help grwo plants like legumes. rhizobia enter into a symbiotic relationship withe legumes
Explanation:
rhizobia and legumes coexist by entering into a symbiotic association. rhizobia is a bacteria that fixes nitrogen molecules for the legumes and in return the legumes provide the bacteria with food and nutrition.
If rhizobia becomes extinct in the near future it would be difficult for plants like legumes to grow as they wouldn't get sufficient nitrogen and nitrogen is an important nutrition for the plant to grow and develop. Thus it can cause rapid depletion or death of plants that need rhizobia to fix nitrogen molecules for them.
