The correct answer is parasitism.
Parasitism, in the field of evolutionary biology, refers to an association between species, where the parasite, the organism, lives on or in another species, the host, creating some kind of harm in it, and is amended structurally to this way of life.
The parasites include protozoans, like as the agents of sleeping sickness, malaria, and amoeba dysentery; animals, like lice, hookworms, mosquitoes, and vampire bats; fungi, like the agents of ringworm, honey fungus; and plants, like dodder, mistletoe, and the broomrapes.
Answer:
The beetles gland stores enough hydroquinone and hydrogen peroxide to allow the beetle to release its chemical spray roughly 20 times. Thus pulsed mechanism is beneficial for the beetle survival because the system uses pressure instead of muscles to eject the spray at a constant velocity, saving the beetle energy.
A frog's lungs don't work that well, but since it's skin is so thin, oxygen and carbon dioxide can pass trough it.
Answer:
Explanation:
The primates have a hand feature which increases their fitness in the tree environment are the opposable thumbs. The thumbs are the broadest digit of the hand. The thumb can move in different directions in comparison to the other digits of the hand. This is an advantage in primates to hold and grasp the objects with their hands.
The monkeys climbing on the trees grasp the branches of trees to move from one tree to another.
Answer:
b. secondary active transport by a symporter
Explanation:
Glucose is a monosaccharide, one of the digestion products of carbohydrates. Glucose is a polar molecule and can not diffuse through the hydrophobic core of the cell membrane of absorptive cells of the small intestine.
A symporter transports one glucose and two sodium ions from the cavity of the small intestine into the absorptive cells of the villi. Since both Na+ and glucose are transported in the same direction, it is a symport. Here, the energy of the ionic concentration gradient of Na+ serves as a source of energy for glucose transport, the process of glucose transport is secondary active transport.
