Leokris [45]3 years ago
8 0

The wing of a penguin is homologous to the arm of a human.

Homologous organs refer to organs of different organisms that are structurally similar but functionally different.

The wing of a penguin and the arm of a human are structurally similar because they are both built on the same pentadactyl or five-digit plan.

Despite the structural similarity, the wing of a penguin and the arm of a human are adapted for different functions. While the wings of a penguin are used to propel the animal in water by flapping them together, the arms of a human are adapted for several functions, including swimming when necessary.

Which is an unseen factor that affects the carrying capacity of the ocean?(1 point)
slega [8]

Sunlight is an unseen factor that affects the carrying capacity of the ocean.

<h3>What is Carrying capacity?</h3>

Carrying capacity may be defined as the maximum number of individuals that can be supported by a habitat.

The other options under this question are water chemistry, water availability, space, and sunlight.

Water availability and space both are unlimited in the ocean habitat, while the water chemistry remains the same throughout the ocean.

Therefore, sunlight is an unseen factor that affects the carrying capacity of the ocean.

amid [387]

Answer:

The correct answer is option B) "The looseness allows for easy separation of the dead cell layer of epidermis to be shed".

Explanation:

The looseness of the surface are connecting the dermis to the epidermis provides several benefits, however allowing for easy separation of the dead cell layer of epidermis to be shed is not one of them. The dead cell layer of epidermis is located a the stratum corneum, which is the most superficial layer of the skin. The area that connects the dermis to the epidermis is deeper at the skin's anatomy, and is not related with the stratum corneum shedding.

The correct answer is option D, Speciation

In the allopatric speciation, the geographical barriers such as mountains or rivers causes isolation of the population. The two population groups get completely separate from each other and thus develop different sexual preferences for mating.

bonufazy [111]

Answer:

Epidermis.

It is composed of keratinized, stratified squamous epithelium and is made up of 4 layers of epithelial cells depending on its location in the body. From deeper to superficial these layers are stratum Basale, stratum spinosum, stratum granulosum, and stratum corneum. The cells in all the layers except for stratum besele are called keratinocytes which is a cell that manufactures and stores the protein keratin.

Stratum Basale.

It is a cuboid-shaped stem cell that is a precursor of the keratinocytes of the epidermis. Two other cell types found in this basal cell are Merkel cells which function as a receptor and are responsible for stimulating sensory nerves that the brain perceives as touch. The second is melanocyte that produces melanin pigment which gives the skin its color.

Stratum spinosum.

It is spiny in appearance due to the protruding cell processes that join the cells via a structure called desmosome. The desmosome cell interlock with each other to strengthen the bond between the cell. Keratinocytes in the stratum spinosum stats synthesizing keratin and release water-repelling glycolipid that helps to prevent water losses from the body.

Stratum granulosum.

They are grainy in appearance due to further change in keratinocytes as they are pushes from the stratum spinosum. The cells become flat as their membrane thickens to allow the production of protein keratin which accolades as lamellar granules within the cells.

Stratum Lucidum.

It is a smooth and translucent layer of the epidermis situated above the stratum granulosum. Keratinocytes containing these cells are dead and flat. Stratum lucidum cells are packs with eleiden derived from keratohyalin which give these cells their transparency and provide a barrier to water.

Stratum corneum.

This is the most superficial layer in the epidermis and it prevents penetration of microbes and dehydration of underlying tissues.

Dermis.-This is the inner layer of the skin and has the following functions.

Reticular layer

Just below the papillary layer, we have a much thicker layer called the reticular layer composing of dense connective tissue. It contains elastin fibers providing elasticity to the skin enabling movement.

Hypodermis
