What is primary succession?
It is a ecological succession that begins in a lifeless area, such as a regions that has no soil or soil of which is not able to sustain life.

Steroid hormones usually diffuse through the plasma membrane into target cells. Thus, the correct option for this question is B.
Steroid hormones may be defined as a type of hormones that are synthesized in the adrenal cortex, the gonads, and the placenta. They are all derived from cholesterol and many are of clinical importance. Steroid hormones are synthesized in the mitochondria and smooth endoplasmic reticulum.
According to the context of this question, lipid-derived (soluble) hormones such as steroid hormones diffuse across the membranes of the endocrine cell. Once outside the cell, they bind to transport proteins that keep them soluble in the bloodstream.
Therefore, steroid hormones usually diffuse through the plasma membrane into target cells. Thus, the correct option for this question is B.

Answer:
( A). sedimentary is a correct answer.
Explanation:
Fossils are the impression or remains of plant and animal present on the layer of sedimentary rocks.
Fossils are usually found in sedimentary rocks, as these rocks are formed on the Earth's surface at low pressure and temperature.
The sedimentary rock contains fossil, as they are formed at low temperature and pressure, due to this fossil remains, are not destroyed.
Thus this the reason Fossils are usually found in sedimentary rock.
Fossils are usually found in sedimetary rock. The correct option is A.
Thus, Sedimentary rocks are typically where fossils are found. Sediments, which may contain animal and plant remains, build up and cement together to produce sedimentary rocks.
These sediments may get lithified over time and solidify into sedimentary rock.
Because the layers of sediment can shield and preserve the remnants of ancient species, fossils are frequently preserved in sedimentary rock, offering important insights into Earth's past and the evolution of life on our planet.
Thus, Fossils are usually found in sedimetary rock. The correct option is A.
