Answer:
E
Explanation:
The picture shown is the cell membrane made of a phospholipid bilayer and proteins embedded. The phospholipid bilayer is made up of hydrophilic (attracted to water) phosphate heads (D), and hydrophobic (repelled by water) tails (E)
The hydrophobic tails face in the way towards each other, while the heads point outwards towards the cell/extracellular environment.
This is because the hydrophobic tails form a conformation that minimizes their contact with water. So you are least likely to find water at E
Answer:
fluid-filled cavity
Explanation:
Rhynchocoel is a fluid-filled tubular cavity present in the organisms of the phylum Nemertea. This cavity lies above the intestines of these organisms in the lower body.
Nemertea is a phylum composed of worms that can be found in shallow water.
These worms have already been classified as a branch of the Flatworms (such as Planarians), with which they are often confused. But recent embryological and molecular evidence points to a phylogenetic relationship with mollusks and annelids. They remind the Flatworms to be non-segmented flat worms. But unlike these, they have a complete bowel with mouth and anus, and a closed vascular system. The article on Planarians can be accessed here.
Answer:mollusks, echinoderms, chordates, and annelids
Explanation: Cladograms are diagrams made to link different organisms to a common ancestor, with the use of Cladograms the relationship between organisms will be established and organisms will be grouped together based on their common features or characteristics.
Molluscs, Echinoderm,Chordates and annelids are of a common ancestor, they are all invertebrates with COELOM.
Chemical energy: When animals eat plant, they get the chemical energy in the plants stored as sugar.Mechanical energy: Carbon dioxide rising through the air gains mechanical energy (as well as gravitational potential energy).Thermal energy: The heating of fossil fuels releases the energy stored inside.Electrical energy: Burning fossil fuels creates electrical energy for us to use.
the answer is true not false i think
