The epidermis is the most superficial layer of the skin. It is composed of stratified squamous epithelium. Within the epidermis,
son4ous [18]

Answer:

a. Stratum corneum 5. : Thick superficial layer of flat, keratinized, dead cells; responsible for dandruff.

b. Stratum granulosum 3.: Cells flatten and fill with keratin, resulting in a grainy appearance.

c. Stratum lucidum 4. : Clear layer found only in thick skin; cells full of keratin.

d. Stratum basale 1. : Deepest layer; site of rapid cell division and melanin production.

e. Stratum spinosum 2.: Live keratinocytes connected by desmosomes produce pre-keratin

Explanation:

The epidermis has five layers, starting from the deepest one they are:

The stratum basale: is the layer that has the germinative cells, called keratinocytes.

The stratum spinosum: the keratinocytes are connected, and they produce the precursor of keratin and lipids.

The stratum granulosum: the name of this stratum is due to the appearance of the cells. They produce keratohyalin, and the lipids produced in the previous layer are released, creating the layer that protects the skin against dehydration.

The stratum lucidum: They are only in thick skin, like the one that is in the sole of our feet. The cells do not have a nucleus. They are filled with keratin, which is the component of thick skin.

The stratum corneum: the more superficial layer, it is made of dead cells filled with keratine. When new cells ascend to this stratum, the old ones have to be removed by exfoliation or natural peeling.

3. Why were germinating seeds used instead of dormant (non-<br> germinating) seeds?
disa [49]

Answer:

An important function of seed dormancy is delayed germination, which allows dispersal and prevents simultaneous germination of all seeds. ... Many species of plants have seeds that delay germination for many months or years, and some seeds can remain in the soil seed bank for more than 50 years before germination.

For larger distances such as the distance between objects in the far reaches of our galaxy astronomers ensure in units of?
Scorpion4ik [409]

Answer:

Lightyears

Explanation:

When dealing with very large interstellar distances, astronomers do not use the regular miles, kilometers, or meters we are used to. This is because they are just too small to be used as a metric when measuring such large distances. As a matter of fact, the earthly number system will quickly be exhausted when trying to measure some of these interstellar distances.

Instead, astronomers make use of Lightyears. Lightyears are defined by the distance traveled by an object moving at the speed of light if it was moving constantly at that speed for one year.

This can properly be used to estimate interstellar distances. since its value is very large. 1 lightyear = 9,461,000,000,000 Km

If we say that our closest star is 9 lightyears away, we are saying that it will take an object moving at the speed of light 9 years to travel from that star to our planet.
