Answer:
I would say that the answer is A. So Sorry if I'm wrong, but I'm 99% sure.
Explanation:
The correct answer is: d. it contains many light-sensing columns called ommatidia
Ommatidia are units that form compound eyes of arthropods such as insects, crustaceans and millipedes (these are invertebrates) and make them very sensitive to motion. Ommatidia are composed of photoreceptor cells (visual detection) surrounded by support cells and pigment cells.
The eyes of vertebrates are more complex showing that progressive improvements in the structure of the eye occurred during the evolution.
Answer:
o The beavers will not have a suitable habitat available and will gradually decline in number.
Explanation:
According to this question, an earthquake that occurs near a river system weakens a dam wall built by beavers, which are aquatic rodents, and causes the dam to collapse. This initial earthquake will damage the habitat of these aquatic animals (beavers), which is barricaded by the walls built by them around the dam over time.
The walls prevent the constant flow of water but when the walls of the dam collapses, the water in the dam begins to flow excessively i.e floods. This causes the loss of habitat of beavers, hence, resulting in the declination of number
Answer:
C. H+ ions do not accumulate inside the thylakoid, so ATP synthase makes too little ATP.
Explanation:
Plant withering refers to the virtual death of plant cells due to lack of food. During the light-dependent reactions of photosynthesis, ATP needed for the synthesis of sugar (food) is created in the thylakoid membrane of the CHLOROPLAST of plant cells.
In the light-dependent reaction, hydrogen ions (H+) builds up/accumulate in the thylakoid lumen to create an electrochemical or proton gradient i.e. a difference in the concentration of H+ ions across the membrane. The hydrogen ions passes through a protein complex called ATP synthase, which forms ATP from ADP (by adding phosphate group), from the energy generated by the electrochemical gradient formed as a result of hydrogen in (H+) build up.
Hence, a plant that possess leaky membrane due to the cold temperature will likely wither because H+ ions are not able to accumulate inside the thylakoid causing a proton gradient, so ATP synthase makes too little ATP.
