Answer: During El Niño, the jet stream is oriented from west to east across the southern portion of the United States. Thus, this region becomes more susceptible to severe weather outbreaks during the winter. Conversely, during La Niña, the jet stream and severe weather are likely to be farther north.

Answer:
Climatic variation
Explanation:
Climatic variation lead to formation of annual rings in the activity of cambium because In climates with alternations of either cold or dry seasons, the growth cells or cambium of wood stems produced when water is available and growth is rapid are always large and have thinner walls and where the climates is dry, the growth is slower and the cambium produced short and thicker walls but where there is uniform climate, there won't be much different as the growth will be uniform.
The cambium is responsible for secondary growth of root and stem.
Answer:
bacteria
Explanation:
bacteria also move in to break down things in ecosystems
Answer: Depends on the balance between blood pressure and osmotic pressure.
Explanation:
The capillaries are part of the microcirculation that transports nutrients to the tissues and removes cell excreta. The walls of the capillaries are extremely thin, constructed of single - layer, highly permeable endothelial cells. Therefore, water, cell nutrients and cell excreta can all interchange quickly and easily between the tissues and the circulating blood.
The tissues of the body is made up of soo many capillaries which helps to deliver blood and it's contents to it. The hydrostatic pressure in the capillaries tends to force fluid and it's dissolved substances through the capillary pores into the interstitial spaces. Conversely, osmotic pressure caused by the plasma proteins( called COLLOID OSMOTIC PRESSURE) tends to cause fluid movement by osmosis from the interstitial spaces into the blood. This osmotic pressure excreted by the plasma proteins normally prevents significant loss of fluid volume from the blood into the interstitial spaces.
Therefore, a balance between hydrostatic pressure in the capillaries which is influenced by blood pressure and osmotic pressure in order for a net flow of fluid into or out of a capillary to occur.
