Explain how water enter the soil root hairs of the plant
Juli2301 [7.4K]

since the roots hairs grow in soil particles, they get water from the soil, thereby the cell wall and cell membrane absorbs the water through osmosis before transferring it to other parts of the roots

Why is it important to study grouse habitat selection and demography relative to human land use practices?
nadya68 [22]
Grouse species have evolved living in environments with little vertical structure and in areas with minimum human activity (from roads and cultivation to other more complex infrastructure). In the recent decades, there has been a significant increase in wind energy development in diverse areas and ecosystems. This development involves construction and placement of tall man-made structures, such as wind turbines and other infrastructure in habitats with high wind capacity. These habitats are often occupied by grouse species. This coexistence could severely endanger the species survivorship and reproductive ability. It is very important to study grouse habitat selection and demography, so that appropriate regulatory guidelines can be applied to wind energy development.

The oxygen that is released as o2 during photosynthesis came from _____________ molecules.
AlexFokin [52]

Answer:

Water (H2O)

Explanation:

Light reactions of photosynthesis release oxygen as a by-product. In the presence of sunlight, photolysis of water molecules occurs. Splitting of two water molecules obtains four electrons, four protons, and molecular oxygen. The oxygen-evolving complex, also called the water-splitting complex is associated with photosystem II (PS II). Splitting of water occurs in the oxygen evolving complex and the released electrons are passed one at a time to the reaction center of PS II. Therefore, a water molecule serves as a source of oxygen released during photosynthesis.

5. Studying light from a star allows us to… a. determine a star's temperature b. determine what elements the star is made of c.
Basile [38]

Answer:

The correct answer is option C "determine how a star is moving (toward, away, fast, slow)"

Explanation:

All realized components emanate and assimilate specific frequencies of light, which is important for the electromagnetic range. By considering the frequencies of light (as demonstrated by 'lines' inside the electromagnetic range) discharged by an object in space, astronomers can get a scope of information.

One thing they look at is the adjustment in situation of lines in the range from a star this can tell astronomers the distance away the star is, regardless of whether it is moving towards or away from us and how quick it is moving.
