The group of the options are given below:
Individuals of population X are predators
Individuals of population X are prey
Individuals of population Y caught and spread a disease.
Individuals of population Y lost their shelters after a flood
Answer:
The correct answer would be - Individuals of population X are predators.
Explanation:
The limiting factor is a factor that prevents or slow the growth of the population. In this case the population an increase of a population results in the decrease in the other population directly.
Increase in the population X results directly in the dcrease of the decrease of population Y. Such relation of the two variables in apopulation growth occurs when there is predator- prey relatioship among two organism or population. Increase in the population of predator result in decrese of the population of prey.
Answer:
Sometimes molecules cannot move through the cell membrane on their own. These molecules need special transport proteins to help them move across the membrane. Facilitated diffusion is the diffusion of substances with the help of transport proteins in the plasma membrane. These special proteins are called channel proteins or carrier proteins, and they are attached to the cell membrane. In fact, they go through the cell membrane, from the inside of the cell to the outside. Facilitated diffusion is used for molecules that cannot diffuse rapidly through cell membranes on their own, even when the molecules are moving from high to low concentration areas. An example is the sugar plants and animals use for energy, called glucose. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient so it does not require the use of cellular energy.
Answer:
Made mostly of collagen, bone is living, growing tissue. Collagen is a protein that provides a soft framework, and calcium phosphate is a mineral that adds strength and hardens the framework. This combination of collagen and calcium makes bone strong and flexible enough to withstand stress.
The easiest example is of Pentadactyl limbs. This is the 5 bone structure of the 'arm' of different animals being similar, contributing to the explanation of common ancestors. Animals that have this are whales, horses, dogs, cows, birds and even humans. We each share the same five bones in similar places but with some of them changed to suit certain functions ie birds are more spread to support flying, while humans are made for throwing, picking up and holding things.
