The shoulder (pectoral) and pelvic girdles are both structures for limb articulation. The shoulder girdles are to the upper limbs as the pelvic girdle is to the lower limbs. Shoulder girdles connect the upper arms with the axial skeleton and consist of the clavicle and scapula.
The pelvic girdles consist of the hip bones, the sacrum and the coccyx and are located between the abdomen and the thighs.
Answer:
A cinder cone is a short, steep volcano that blasts out
pyroclastic material.
Explanation:
A cinder cone is basically a sharp conical hill which consist of a loose pyroclastic fragments that are being formed on the sides on volcanic vent.
Simply think of a steep volcano and how it acts when it blats out, this is what cinder cone is. When the lava is blown out in a very violent manner, it breaks in to very small particles that can be addressed as cinder. Almost all the cinder cones are made up of pyroclastic substance.
I don’t know the second part, but algae growth will increase as a result of the fire
Answer:
b, a, d, c, e
Explanation:
The lac operon is called lactose operon is a cluster of genes with a promoter. The bacteria uses lactose as the source of energy by the proteins coded by genes. This is present in prokaryotes.
The regulatory gene codes for repressor protein. The repressor binds to lactose and prevent its binding to operator. In the absence of lactose repressor gets activated and binds with operator. Thus, RNA polymerase is prevented from binding the promotor. The transcription of genes inhibited. Thus correct order is b, a, d, c, e.
The logistic growth curve is given by the differential equation,

When the rate of change in population approaches the maximum carrying capacity, the curve starts to flatten or become saturated.
The left hand of the differential equation becomes zero and attains a steady state equilibrium at,


Hence, at
.
The right end of the logistic growth curve shows the flattening of the curve while reaching the maximum carrying capacity.
