Answer:
They evolved from entirely different ancestors, but both developed wings in response to similar ecological conditions.
Explanation:
Based on the info given, they possibly could have had the same ancestor, but even if that was true, the bat would have some type of resemblance other than wings. I think that due to environmental changes, natural selection allowed these organisms to fly so they can survive in that environment. Birds got feathers because they could have been in a cold ecosystem so they needed warmth for themselves and their young as well as stay away from predators, due to their small size they had no way to get away without wings. They didn't have legs for running so they developed wings. Bats may have been in a fine temperature, but the day caused problems due to hunting, so they developed wings to hunt at night and keep themselves in caves to hide from predators.
This is the best I could do, I hope this helped :)
Answer:
Two back-to-back phospholipid layers with the polar heads facing out on both sides
Explanation:
Phospholipids are made up of a head and two tails. The head can be described as a phosphate molecule that is water loving (hydrophilic) whereas fatty acids make up the two tails. The fatty acids repel water and hence are hydrophobic. The assembling of the phospholipids for the the formation of cell membrane depends on these hydrophilic and hydrophobic properties. The assembling of the phospholipids is in two layers. The phosphate head face outwards on both sides to attract water and the tails tend to hide from the water molecules by being composed in the layers of the head. this assembling is termed as the "self-assembly".
Answer:
Yes.
Explanation:
The burning candle is converting chemical energy—stored in the hydrocarbon bonds in the wax—into thermal (heat) and radiant (light) energy. The energy transforms from chemical energy to heat and light energy. Because when the candle burns a chemical reaction occurs, and produces heat and light
Skin serves as a protective barrier, a way to sense the world, and a layer that keeps nutrients and water inside the body. Four types of cells make up the skin, and they are produced mainly in the epidermis near the basement membrane.
Answer:
The defective CFTR protein changes ion influx and efflux across the body's cell membranes, which ultimately changes the internal environment of these cells. This change contributes to each cell's production of proteins through transcription and translation.
