Answer:

1) pathway taken by water

water is absorbed from the soil, through the root hair cells and is transported by the xylem vessel up the stem to the leaf and/or flowers. From the leaf, some water is lost to the atmosphere as vapors escape out through the stoma present in the lower epidermal layer of the leaves.

2) water potential gradient

water potential refers to the concentration of water present. A gradient forms when there is a difference between the concentrations of water in two regions separated by a partially permeable membrane.

Hence, water moving down a water potential gradient means that it goes from a region of high water potential to a region of low water potential.

3) There are tiny openings on the lower side of the leaves called as stomata (plural: stoma) that allow for gaseous exchange to occur. These openings are controlled by guard cells which are open during the day and close during the night.

Hope that answers the question, have a great day!

Answer:

1. The pathway of water in plants is described as follows:

Water moves from the root of the plant to the xylem, from the xylem to mesophyll, from the mesophyll water diffuses out of the plant through the stomata.

2. Water potential gradient is the direction through which water moves in a plant

3. The STOMATA is the structure that allows necessary gases to enter and water to leave

Explanation:

1. The pathway of water through plants can be described as follows:

Water enters into plants through the hairs found on the roots of plants. From the roots of plants, water moves into xylem, from the xylem water is transported to the mesophyll. From the mesophyll , water diffuses out of the stomata as water vapour.

2 Water potential gradient is the pathway through which water moves through a plant

3. The stomata are pores that are located on the surface of leaves and stems of plants. It plays a very important roles in plants during transpiration. The stomata allows essential gases such as Carbon dioxide to enter into plants and allows water to leave the surfaces of plants as water vapour through the process of diffusion.

Zigmanuir [339]

Answer:

Atoms are the smallest units of matter that still retain the fundamental chemical properties of an element. Much of the study of chemistry, however, involves looking at what happens when atoms combine with other atoms to form compounds. A compound is a distinct group of atoms held together by chemical bonds. Just as the structure of the atom is held together by the electrostatic attraction between the positively charged nucleus and the negatively charged electrons surrounding it, the stability within chemical bonds is also due to electrostatic attractions. To illustrate further, consider the two major types of chemical bonds: covalent bonds and ionic bonds. In covalent bonds, two atoms share pairs of electrons, while in ionic bonds, electrons are fully transferred between two atoms so that ions are formed. Let’s consider both types of bonds in detail.

In areas of permafrost, stands of black spruce are frequently observed in the landscape, while other tree species are noticeably
Marizza181 [45]

This happens because taproot formation is impossible, so trees developed shallow root beds.

Permafrost is soil that has a temperature below 0 °C (for about two years) and forms a solid matrix which can extend to a depth of hundreds of meters. Because of this structure the permafrost prevents trees from developing deep root systems. As a consequence, the shallow root bed of trees such as black spruce, causes them to lean or even fall.

inysia [295]

Answer:

Montesquieu said that "every man invested with power is apt to abuse it, and to carry his authority as far as it will go". Agree with this statement.

Explanation:

In the book, "The Spirits of the Law", Montesquieu wrote that powers of a government should be divided between three: legislative, executive and judiciary. This separation is important to make sure that a single group of individuals are not given too much of a power. This would ensure that power is not abused.

He said that history has proved that political power has always been abused by a person who has it in abundance. So, to promote political liberty he thought it is important that there are separate branches of powers in a government.

So, Montesquieu made such a system with checks and balances so that no man uses law to do things he shouldn't do and also he refrains from doing what he is allowed to do.

What is the alien invasion in the Florida Everglades?​
NISA [10]
The foreign Burmese Python has disrupted the entire animal population in the Everglades. These invaders from Asia have proved to be extremely detrimental to Florida’s ecological systems, based on factors including their size, rapid reproduction, predatory diets, and Florida’s weather and climate conditions. Due to these multiple elements, Burmese Pythons have taken over the Everglades and have shown no signs of stopping. The problem becomes even more difficult to handle when the environmental controls taken to remove these pythons fail to counter the increasing python population in the Everglades. In other words, because of the biology of these snakes, the problems they bring to the South Florida food chain and the lack of removal of the invasive predators, Burmese Pythons create major issues for the ecosystem and are likely to spread if not controlled quickly. Hope that is enough! :)
