I believe the answer is C, as when the sun is tilted at different angles different places will get different amounts of sunlight.
Explanation:
The phospholipid bilayer forms the outermost layer of cells called the plasma membrane of the cell.
The phospholipids are arranged in the bilayer with the globular head composed of glycerol and the phosphate on the outer side (hydrophilic) and the hydrophobic carbon chain in the inner side.
The hydrophobic molecule present in the layer provides a characteristic feature to the membrane that is known as selective permeability. The selective permeability allows the non-polar or uncharged molecule to pass through the membrane and not the large polar molecules.
This is because the non-polar molecules can interact with the hydrophobic portion (tails) which could allow the molecules to pass through the membrane but the polar molecules are repelled by the hydrophobic protein so require special channels.
They would die or have to have food digested for them.
Answer:
Embryological evidence
Explanation:
Deuterostomes is a group that includes echinoderms, hemichordates, and chordates. Although these animals exhibit a wide variety of body plans, they share a mouth secondarily formed during embryo development, which it is believed to be an evolutionarily derived character present between a common ancestor and all its descendants (i.e., a synapomorphy). This oral cavity is formed by the invagination of the ectoderm layer opposite to the blastopore of the gastrula.
