The epidermis is the most superficial layer of the skin. It is composed of stratified squamous epithelium. Within the epidermis, there are five distinct layers with different features and roles. Match the appropriate skin layer with its description.
a. Stratum corneum
b. Stratum granulosum
c. Stratum lucidum
d. Stratum basale
e. Stratum spinosum
1. : Deepest layer; site of rapid cell division and melanin production
2. : Live keratinocytes connected by desmosomes produce pre-keratin
3. : Cells flatten and fill with keratin, resulting in a grainy appearance
4. : Clear layer found only in thick skin; cells full of keratin
5. : Thick superficial layer of flat, keratinized, dead cells; responsible for dandruff
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.
The five distinct layers of the epidermis with different features and roles are given below: a) Stratum corneum- 5, b) Stratum granulosum- 3, c) Stratum lucidum- 4, d) Stratum basale-1, e) Stratum spinosum- 2.
The epidermis (outer layer of the skin) is the part of the skin that’s visible to the unaided eye and works to protect the body. The epidermis doesn’t have any blood vessels, so it relies on the dermis (the layer of skin directly beneath the epidermis) for nutrients and waste disposal.
The epidermis protects the internal organs, the muscles, the nerves, and the blood vessels. The epidermis also creates new skin cells and produces melanin, which gives the skin its color and reduces the absorption and effect of UV radiation. It protects the body physically, and it also protects the immune system.

Why do heart cells have different characteristics than skin cells?
Heart cells have different DNA than skin cells.
Heart cells express different genes than skin cells.
Heart cells reproduce by cell differentiation.
Heart cells reproduce by mitosis.
Answer:
Heart cells express different genes than skin cells. B
Heart cells have different characteristics than skin cells because heart cells express different genes than skin cells.
Humans as multicellular organisms possess different cells in our body system. These cells perform varying functions in the body. The different functions performed by different cells is attributed to the cellular differentiation. Cellular differentiation is the process whereby an undifferentiated cell becomes specialized. The cellular differentiation occurs due to the difference in gene expression in each specific cell. All cells contain the same DNA sequence, however, they are expressed differently. Therefore, heart cells have different characteristics than skin cells because heart cells express different genes than skin cells.Learn more at: https://brainly.com/question/18546772?referrer=searchResults
In conservation plowing, why are dead weeds and stalks of the previous year's crop left in the ground?
a. to keep the soil from becoming too fertile
b. to reduce the amount of seed needed for the next year's crop
C. to retain moisture and hold the soil in place
d. to keep more organisms out of the soil
Answer:
to retain moisture and hold the soil in place.
Explanation:
this technology of putting dead plants on the soil under the plants and the area nearing the plants is called mulching.it is helpful in reducing the rate of evaporation and also reduces soil erosion.
Conservation plowing is achieved to minimise soil erosion. Thus, option C is correct.
What is soil erosion?Soil erosion is the deterioration of the topmost layer of soil. The top fertile layer of the soil withers leaving the soil infertile.
It is a gradual naturally occurring phenomenon but can be accelerated with human interventions.
There are many factors responsible for soil erosion:
• Deforestation
• Excessive grazing
• Mining
• Construction work
• Drought and floods
Soil erosion negatively affects the crop yield and also clogs the water bodies. This is therefore harmful for the aquatic species. Dry and barren soil is more prone to floods.
Soil erosion should be minimized as it produces a negative impact on the ecosystem.
Soil erosion can be prevented by planting more number of trees. The roots of the trees help in holding the soil in its place.
Therefore, soil erosion should be checked to preserve the soil fertility.

What is colon cell?IECs, which line the surface of the intestinal epithelium, are crucial for food digestion, nutrient absorption, the body's defense against infections from microbes, among other functions. Adenocarcinoma, the most prevalent type of colon cancer, develops in the glands that secrete mucus and is the primary cause of colon cancer diagnoses.In order to regulate mucosal immunity, coordinate food recycling, and create a mucus barrier, the colonic epithelium allows host-microorganism interactions. Inflammatory bowel illness is caused by a breach in the epithelial barrier (IBD).A colon polyp is a little cell cluster that develops on the colon's lining. Colon polyps are usually not harmful. But over time, certain colon polyps can transform into colon cancer, which, if detected in its later stages, can be fatal.

Answer:
Plants make their own food with the help of photosynthesis, in which the organic carbon is formed from the inorganic carbon. Organic carbon is used as a source of energy and helps in various cellular functions.
Organic carbon mostly stored in the form of starch and other carbohydrates and also helps in forming the structure of the plants. The starch is stored mainly in the roots, fruits and stems. The main source of starch is in roots in tubers of the plants. The radioactive carbon that is found in the plant roots in the experiment is the excess carbon that stored in the roots of the plants
