The reticular layer is composed of dense irregular connective tissue whose strength and toughness results from abundant collagen fibers.
The reticular dermis of the skin has many collagen fibers to support it because it provides strength and acts as a cushion. It also has elastin fiber that makes it elasticity.
Answer:
Water vapor and clouds are the major contributors to Earth's greenhouse effect, but a new atmosphere-ocean climate modeling study shows that the planet's temperature ultimately depends on the atmospheric level of carbon dioxide

<em><u>One of the best ways to determine if a tree or any plant is dead is the tree scratch test. Just beneath the dry, outer layer of bark in a tree's trunk lies the cambium layer of bark. In a living tree, this is green; in a dead tree, it is brown and dry</u></em>

When a pathogen comes in contact with your body, it has to breach the first line of defense to get inside. Your skin and mucus membranes are the main barrier here. Mucus traps the pathogens, and then is forced out of your body when you cough or blow your nose. Your skin also secretes chemicals that have antiviral properties, killing viruses on contact. If the pathogens get through that defense, the next line is non-specific immunity cells that patrol your tissues engulfing pathogens. There are other cells that do this, like macrophages, but the dendritic cells are most important for activating the third line of defense in your body.
Dendritic cells reside in your tissues, waiting for an invader to arrive. When they do find one, they engulf it and digest it. After they do this, they select pieces of the invader called antigens and put them on their surfaces. The dendritic cells migrate back to lymph nodes, key locations in your body filled with immune cells. There, they show the antigens, called antigen presentation, to two types of lymphocytes, T-cells and B-cells, activating them for a full immune response.
