The answers are A, B, & C. Steroid hormones have a
longer half-life than peptide hormones because steroid hormones ride on carrier
proteins in the blood. In other words, they
are bound to protein carriers that transport molecules across the membrane. They can also be stored temporarily in the adipose
tissue. And also, steroid hormones are sent to the nucleus where it regulates transcription
while peptides don’t require this process. This is the reason why the effects of
steroid hormones are exerted more slowly than peptides.
The answer is letter A.
Dogs grow a thick coat fur during winter because they are adapting to change. Adaptations are
the result of evolution in different living organisms. This process occurs amazingly
through gene mutation but it takes a very long period in time. Adaptation
processes occur to help species survive and thrive in the ecological balance of
life.
Structural adaptations are physical features of an organism that adapted
through time. An example of this is the thick coat of fur that dogs naturally grow to protect themselves from the change of the weather.
I believe the answer is 3.
