The technology can help scientists study or look at cells, which in turn can let those scientists figure out if a cell is infected with a virus, or if it's a mutated cell that might cause a disease.
Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane. Carbon dioxide, the byproduct of cell respiration, is small enough to readily diffuse out of a cell. Small uncharged lipid molecules can pass through the lipid innards of the membrane.
Answer:
D. is responsible for most of the skin's structural strength.
Explanation:
A. contains no blood vessels.
False. The dermis contains blood vessels together embedded in it along with the sweat and sebaceous or oil glands, hair follicles, and nerve endings.
B. functions as a padding and insulation.
False. The fat layer that is located below the dermis is the one responsible for padding and insulation.
C. is divided into three distinct layers
False. The dermis is divided into only two separate layers. These are the papillary layer or the upper layer and the reticular layer or the lower layer.
D. is responsible for most of the skin's structural strength.
Yes, the dermis functions for providing the skin's structural strength because of it's thick fibrous and elastic tissue layer. This layer consists primarily of collagen and elastin that also allows for the skin's flexibility.
E. is made of epithelial tissue.
False. The dermis is made up of fibrous and elastic tissue. It is the epidermis which is composed of the epithelial tissue.
Fact: <span>Organisms are classified based on their physical characteristics. For example, some organisms have a backbone, and other organisms do not have a backbone. Some organisms are single-celled, and other organisms are multi-celled. The classification order that scientists use is Domain, Kingdom, Phylum, Class, Order, Family,Genus, and Species.
</span>Evidence: Je<span>llyfish and corals cannot be called zoophytes, meaning animal-plant. They are neither animal nor plant but have characteristics of both groups.</span>
