Answer:
The polar bear is an animal which is prevalent in the arctic region of the world which is characterized by very cold icy climate.
They adapt to these climatic conditions by maintaining a body temperature of 37°C through its thick fur and tough skin. It also has an insulating fat layer (adipose tissues) which is very thick.
This insulation helps in keeping the animal very warm in extreme temperatures.
<span>The answer to the question that is being presented above would be K-selected. Sperm whales, which have adapted to live in equilibrium at carrying capacity for a long time, are referred to as the K-selected kind of species.</span>
Answer:
Threonine has two chiral centers.
The correct options are c. carbon b and d. carbon c
Explanation:
Chiral centers are those that have four different groups of atoms bonded to it. Carbon a has three atoms of hydrogen attached to it so it can't be a chiral carbon. It isn't the carboxyl carbon either since it is double bonded to oxygen. And the amino nitrogen does not qualify anyway because it is bonded to three different groups of atoms, not four.
What do you think the answer is then I can help you change your answer around.<span />
Plasma proteins account at least 8% of the plasma, they contribute to osmotic pressure and maintain water balance in blood and tissues, other functions includes transport and enzymatic activities. Plasma proteins include albumin, fibrinogen and globulin (alpha, beta and gamma). Globulin proteins may be used to fight infections such that gamma globulin antibodies are released by the plasma during immune response.
