What is albumin and what is gelatin? how can one differentiate between the two?

Albumin can be described as a family of proteins consisting of globular proteins where as Gelatin can be describes as a substance which is derived from a protein called collagen.

Explanation:

Albumin are a class of proteins mainly monomeric proteins.

The properties of albumin are:

1.  They are soluble in water.

2. They can be coagulated by heat.

3. They are present in milk, egg white etc.

The functions of albumin include:

1. They are carrier molecules for substances for thyroid hormones, fatty acids as well as steroids.

2. They stabilize the volume of extracellular fluid.

Gelatin is a protein that is made by partially hydrolyzing collagen. Gelatin is used for making edibles like jelly. Gelatin also serves as the translucent membrane which is used for filtration  in photography.

the darker peppered moth species were favored due to the fact that the industrial revolution had made all the nearby trees a darker color instead of white.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
