Lymphatic capillaries are tiny vessels determined in the tissues of most organs in your body. They transport and clear out lymphatic fluid (lymph) out of your frame's cells and tissues. Lymph capillaries assist to preserve steady blood stress and extent and save you fluid buildup.
Lymph capillaries are found in all regions of the frame besides the bone marrow, important frightened system, and tissues, which include the epidermis, that lack blood vessels. The wall of the lymph capillary is composed of endothelium wherein the simple squamous cells overlap to form a easy one-way valve.
Lymphatic vessels collect and filter lymph (on the nodes) as it keeps to transport towards large vessels referred to as gathering ducts. these vessels operate very similar to your veins do: They work under very low strain, have a chain of valves in them to maintain the fluid moving in a single route.

Write a story about a carbon atom on its path through cell respiration and photosynthesis. Please help me
The story is a carbon dioxide is pulled from the air to produce food made from carbon for plant growth.
Carbon atoms start out as part of glucose. During cellular respiration, glucose is broken down into smaller carbon molecules. Eventually, the carbon atoms in carbon dioxide are released into the atmosphere. During cellular respiration, carbon dioxide is released as a waste product.
This carbon dioxide can be used by photosynthetic cells to form new carbohydrates. Oxygen gas is also required for cellular respiration to serve as an electron acceptor. They use the sun's energy to chemically combine carbon dioxide with hydrogen and oxygen from water to form sugar molecules. Photosynthesis produces glucose that is used in cellular respiration to produce ATP. The glucose is then converted back to carbon dioxide.

The transpiration pull is due to the ________ that causes water to move up through the xylem that begins at the surface of mesophyll cells.
The transpiration pull is due to the negative pressure potential that causes water to move up through the xylem that begins at the surface of mesophyll cells.
Transpiration is the process in which the water travels through the plant and evaporates through the open surfaces of plant like stem, leaves or flowers. Stomata is the main component in the leaves and stem that causes transpiration.
Negative pressure potential arises due to high content of solutes in any cell. The top of any plant is high on solutes while the bottom or root part has optimum amounts of water. This is the reason why the abundance of solute and negative pressure potential causes the water to rise up.

how has the change in land use affected the balance of photosynthesis and respiration? how could we change land use to stabilize or reverse this trend?
If there is a change in land use, it will cause the plant to decrease so that the reduction in carbon storage is also reduced, so it becomes a contributor to global climate change. To stabilize this situation, we can use land with go-green innovations.
The by-product of respiration is CO₂ which will be released into the atmosphere. The process of photosynthesis in plants requires CO₂ from respiration. When there is a change in land use, it will cause a decrease in vegetation so the reduction in carbon storage is also reduced. So, the atmospheric concentration of CO₂ (carbon dioxide) from respiration will increase thereby contributing to global climate change.

The pacemakers are thought to be the interstitial cells of Cajal, which are clustered between the layers of smooth muscle tissue. These cells exhibit slow waves, which are rhythmic, spontaneous oscillations in membrane potentials that occur anywhere between three times per minute in the stomach and twelve times per minute in the duodenum. Parasympathetic innervation affects the vagus nerve's reaction. Because of increased vagal activity, which may result in diarrhoea, GI motility is improved.
