2.blending into their environment

3. birds migrate to survive the cold. they go into warmer climates where there will be food available. when they hibernate it’s to keep the animal warm during the winter using there stored body fat.

4.instincts are behaviors animals inherent from their mother. a learned behavior is something they learn from practicing new behaviors.

5. they blend into there habitat because they are very colorful like the coral reefs they live in so it’s difficult for predators to see them.

Consider the parts of a polar ecosystem and a desert ecosystem.
g100num [7]

Answer: Abiotic factor for polar: Ice

Abiotic for desert: Sand

Biotic for polar: Polar bears

Biotic for desert: Cacti

The types of factors are different because there are different set conditions for each ecosystem. A cactus is built for it's hot, dry ecosystem. If it were to move to a polar ecosystem it would not survive there. Same for the polar bear. It's built for polar regions. It has white fur to blend with the white ice to help it blend in and it's adapted to swim to get it's food source.

The diagram shows an experiment on the digestion of the protein in egg albumen by protease.
laila [671]

Answer:

<u>C</u>. containing

  • <u><em>egg albumen </em></u>
  • <u><em>protease </em></u>
  • <u><em>dilute  hydrochloric  acid</em></u>

Explanation:

A protease is a kind of peptidase enzyme that breaks down proteins into peptide molecules. As a digestive enzyme it is located in the lining of the stomach where, relative to the hydrochloric acid in digestive juices, the pH is usually low/ acidic.

<em>Enzymes speed up reaction rates by </em><em>providing alternative pathways</em>. By modifying the enzyme composition, supplying more collision energy, and changing the collisions between and the ratio of reactants, certain variables will increase the reaction rate.

Proteases function well at 37℃, the typical internal temperature of the human body- this temperature provides adequate energy for the reaction. Similarly, proteases require low pH for the correct configuration, and beyond this pH and temperature, they may become denatured or simply not function well as catalysts.
