The use of more resources lead to a decrease in resources, therefore the need for more resources. More people means the more need for shelter. More people means more industrialisation to provide for the needs and wants of life.
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

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.
Humus is a dark organic matter that is an important part of your soil
Humus consists of decomposing organic material. The process of creating humus is called Humification: decomposition of o<span>rganic matter into smaller and smaller molecules by the micro-organisms in the soil (mostly bacteria and fungi).</span>
