Photosynthesis requries a supply of CO2 as well as H2O and sunlight. how do plants obtain these resources?
H2O is acquired by osmosis in the plants cells, and or through the stomata. CO2 is obtained in the way of the stomata.
What do you mean by osmosis?In biology, osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's partially permeable membrane.
Moreover, the spontaneous passage or diffusion of water or other solvents through a semipermeable membrane (one that blocks the passage of dissolved substances—i.e., solutes).
Hence, osmosis is the transport of a solvent through a semipermeable membrane that separates two solutions of differing solute concentration. During osmosis, the solvent moves from the solution that is lower in solute concentration to the solution that is higher in solute concentration.

Taconite is a low-grade iron ore that is found around Lake Superior. The iron-bearing rock is found interlaced with quartz, chert and other minerals. The iron is separated out of the taconite using magnets so that it can be processed to for use in the production of steel in nearby states. What statement does not represent a concern by the Department of Natural Resources about the use of taconite as a source of iron.
A) The process to separate iron from taconite requires transportation by large vehicles over public roads.
B) The separation of taconite involves chemicals that may lead to air and water and pollution.
C) The area where taconite is mined is characterized by wetlands and streams.
D) Taconite is a non-renewable resource.
Answer:
Option (D)
Explanation:
Taconite is a silica-rich and low-grade ore of iron. This iron ore was initially considered to be a waste rock due to the abundance of higher-grade natural iron ore. But now, with the decreasing amount of natural iron ore, the use of taconite is increasing. They are extremely hard rock and the iron ore present in this rock is extracted by the use of magnetism. Due to the heavier weight, these rocks are needed to be transported from one place to another using very heavy vehicles.
These rocks are obtained by the smelting process in which carbon is used to heat the iron ore. This emission of carbon into the atmosphere can contribute to pollution.
These rocks are usually found in the streams and wetland areas. They are abundantly present on earth and not a non-renewable resource.
Hence, the most appropriate answer is option (D).

what observable characteristic could be used to identify this rock sample as gneiss
Gneiss can be identified by its foliated texture with alternating bands of light and dark minerals, and sometimes eye-shaped quartz masses known as augen; it is a high-grade metamorphic rock formed from schists or granites.
Explanation:The observable characteristic that could be used to identify a rock sample as gneiss is its distinct foliated texture. Gneiss is a high-grade metamorphic rock characterized by alternating bands of light and dark-colored minerals, typically quartz and biotite mica. The surface of gneiss may also feature augen, which are eye-shaped masses of quartz that give rise to the term augen gneiss. This rock typically forms from the metamorphism of schists or granites and is a product of high-grade metamorphism, where minerals have segregated into distinct layers due to intense heat and pressure.
Final answer:
The observable characteristic that can be used to identify the rock sample as gneiss is the presence of alternating bands of light- and dark-colored minerals.
Explanation:
The observable characteristic that can be used to identify the rock sample as gneiss is the presence of alternating bands of light- and dark-colored minerals. Gneiss is a high-grade, foliated metamorphic rock, and these alternating bands are a result of the intense metamorphism that has caused minerals to self-segregate into discrete zones. In the case of gneiss, the bands are often composed of minerals such as quartz and biotite mica.
Consider the following food chain: garden plants are eaten by snails, which are eaten by birds, which are eaten by the household cat. What happens to the other members of the food chain if the cat is removed?
If the cat is removed the population of birds will escalate and exceed the population of the snails that sustain them.
The food chain is a depiction of the feeding relationship that exists in an ecosystem. An ecosystem is a self-supporting unit in which materials and energy are exchanged.
The food chain is as follows;
garden plants --> snails ---> birds --->household cat. We can see that removal of the cat means that the population of birds will escalate beyond the available population of snails. This will lead to competition for food among the birds within the ecosystem. The population of snails will suddenly decrease due to increase in the number of their predators. The number of garden plants will also increase due to the decrease in snail population.
