Build a dichotomous key to all the tissues you have seen in the lab. For this, you can use any of their morphological characteri

Mrac [35]

Answer + Explanation

Epithelia:

Simple squamous epithelium :single layer, flattened cells

Simple cuboidal epithelium : single layer, cube shaped cells

Simple columnar epithelium : single layer, elongated cells

Pseudostratified columnar epithelium : single layer, elongated cells

Stratified squamous epithelium : multilayered layers, top cells flattened

Stratified cuboidal epithelium : multilayered , cube shaped cells

Stratified columnar epithelium :top layer of elongated cells, lower layers off cube shaped cells

Transitional epithelium: many layers of cube shaped cells and elongated cells

Goblet epithelium : unicellular or multicellular.

Connective tissue ---

Areolar: consist of fibroblasts, macrophages, adipocytes, mast cells, plasma cells

Loosely arranged collagen, reticular and elastic fibers an gelatinous ground substance.

Adipose : adipocytes, fibres are reticular and collagen

Closely packed cells with a small amount of gelatinous ground substance.

Hyaline cartilage : chondrocytes, collagen fibers

Limited ground substance, dense and gel matrix.

Elastic cartilage : chondrocytes, elastic fibers

Limited ground substance, flexible but firm gel matrix.

Fibrocartilage: chondrocytes, collagen fibers

Limited ground substance intermediate between Hyaline cartilage and dense connective tissue.

Bone--- osteoblasts and introduced cells ,collagen fibres

Blood --- erythrocytes, leukocytes, platelets

Muscle ----

Striated skeletal muscles have characteristic cross-striations which are due to the regular arrangement of contractile elements, the sarcomeres.multinucleated.

Cardiac muscle are strained. Branched and shaped like fibers cross each other. One nucleus per cell.

Smooth muscles, as their name implies, do not have cross-striations. They are generally lighter in color than striated muscles.one nucleus per cell.

Both neurons and global cells consist of cell bodies and cell processes

Damage to the enteric nervous system that innervates the digestive organs could affect:

Fudgin [204]

I think the damage to the enteric nervous system that innervates the digestive organs may affect the motility. The digestive motility or the gastro intestinal motility is defined by the movements of the digestive system, and the transits that contents within it. If the nerves or muscles in any position of the GI tract do not function with their normal strength and coordination, an individual develops symptoms related to motility problems.

An individual who consumes no animal-based foods of any kind, no fortified foods, and no supplements is at increased risk for an

mafiozo [28]

<span>The answer would be macrocytic anemia.

</span><span>Macrocytic anemia is lack of red blood cells that caused by B12 deficiency. Vitamin B12 is mostly found in animal products (eggs, dairy product or honey) so vegan will have increased risk of deficiency. Vegetarian that doesn't eat meat also at risk of iron deficiency that will cause microcytic anemia.</span>

Compare & Contrast the 4 parts of Evolution and the 3 "Ingredients" of Natural Selection."

Klio2033 [76]

The four parts of evolution are variation, inheritance, selection, and time.

The three ingredients of natural selection are variation, consequences, and heritability.

Explanation:

Parts of evolution:

Variation denotes the uniqueness in genetic makeup which leads to physical differences among different species and within species. Like in a species of butterflies, variations in body size, color, feathers can be observed.
Inheritance refers to the genetic material passed from the parents to the offsprings. These are specific phenotypes like color of skin or hair, shape of nose etc.
Selection includes inheritance and acquiring of certain phenotypes to adapt and survive better, reproduce offsprings. These new offsprings in turn produce new offspring with those phenotypes and result in the entire population.

Time decides about the various changes and adaptations in species. Certain evolutions like that of whale happened millions of years ago; however, the numerous viruses have evolved recently.

In natural selection,

Variation is the change in the individual traits.
Consequences are adaptation of certain traits by individuals which makes them to be better to survive and reproduce
Heritability refers to the resemblance of the offspring to their parents.
