Sinkholes are formed when land collapses into cavities underground. A few causes of sinkholes are disturbance of soil (digging for example), water impoundment (dams and basins), and decline of water level (groundwater pumping and droughts).

kotykmax [81]

Answer:

basale - spinosum - granulosum - lucidum - corneum.  

Explanation:

The order of strata in the epidermis:

  • Basale: it is the deepest stratum. It has one layer of cells called keratinocytes, which are stem cells for the epidermis.
  • Spinosum: The keratinocytes in this layer have spiny shapes. They synthesize cytokeratin and lipids. In this layer, we can also find macrophages.
  • Granulosum: The keratinocytes of the previous layer ascend and synthesize keratohyalin, which is in granules. The keratohyalin helps to join keratin filaments. Also, the cells release the lipids synthesized in the previous layer, and they form a barrier that stops dehydration.
  • Lucidum: it is only on thick skin, like the one in the sole of the feet. The keratinocytes in this layer have expelled the nucleus and now are dead cells. The keratinocytes have a flat shape and form a thin layer.
  • Corneum: it is the most superficial layer. It is made of dead keratinocytes filled with keratin in their cytoplasm. It is a thick layer that suffers desquamation when new dead cells filled with keratin ascend from the previous layer.

In single-gene traits, natural selection can lead to which of the following?
ivanzaharov [21]

Answer;

-Allele frequency change

In single-gene traits, natural selection can lead to allele frequency change.

Explanation;

-Allele frequencies can change over time within a single population, and frequently differ between populations. This change is due to four different processes: mutation, selection (natural and artificial), gene flow and genetic drift.

-Random forces lead to genetic drift. Sometimes, there can be random fluctuations in the numbers of alleles in a population. These changes in relative allele frequency, called genetic drift, can either increase or decrease by chance over time.
