A biology class in Virginia conducted a survey of the plant species found on their school grounds. They found several plants that they didn’t recognize. What resources would be most helpful to the class in identifying the plants and determining if they were introduced as exotic species?
This is a multiple choice
1). Virginia newspaper and science journals
2). Biology textbooks and the encyclopedia
3). Virginia native species checklists and plant identification keys
Can someone tell me the answer and explain how you got it please?
Answer:
c
Explanation:
I would say C because then you can identify if it was introduced as an exotic species if it is not native. Then you will also be able to identify what type of plant it is with the key.

Answer:
1) Diffusion : Is the movement of molecules / ions from a region of higher to lower concentration. It may or may not occur across a semi permeable membrane.
In diffusion there is no challenge involved as it is along the concentration gradient, but in active transport movement of molecules occur against concentration gradient ie; from lower to higher concentration.
2) For active transport, energy is vital for movement, in this case protein molecules function as molecular pumps to enable the cell accumulate glucose/ions, against concentration gradient. Here metabolic energy ATP is required.
3)Facilitated diffusion is a type of passive transport in which ions/molecules cross the semi permeable membrane because permeases present in the membrane facilitate the transport.
Like simple diffusion facilitated diffusion doesn't require metabolic energy and simply occurs across the concentration gradient.
4) Osmosis : is movement of water from hypotonic solution (lower concentration) to hypertonic solution (higher concentration) through a semi permeable membrane.
The cell membrane being permeable to water allows to and fro movement of water molecules along the concentration gradient.
What do Pulmonary veins carry?
Answer:
Pulmonary veins: The veins do the opposite job of pulmonary arteries and collects the oxygenated blood and carry it from the lungs back to the heart. The veins merge into larger veins. Each lung has two pulmonary veins that deliver blood to the heart's top left chamber or atrium.

18. Explain how large, carbon-based molecules are formed
Answer:
All three types of molecules are the result of carbon's ability to form four covalent bonds. Carbon chains can bond with carbon rings to form very large, complex molecules. These large molecules can be made of many small molecules that are bonded together.

Each X shows the location of an archer's arrow on a bull's-eye target. The archer was aiming for the center circle. X xx X x x Which words best describe the archer's results?
Low precision and low accuracy best describe the archer's results. So the correct option is A.
Who is an archer?Archery is a sport that involves firing arrows with a bow at inanimate objects or animals during a hunt.
With the exception of Australia, the bow has been a primary tool of combat and the hunt from prehistoric times.
Ancient Egyptians and Greeks also engaged in recreational archery in addition to military archery, an example of the latter being the contest in which Odysseus triumphed and gained Penelope's hand.
Large portions of Asia were ruled by horse-mounted archers such as the Huns, Seljuq Turks, Mongols, and others for around 15 centuries beginning in the first century CE.
During the Hundred Years' War (1337–1453), English longbowmen earned magnificent military successes, while the crossbow gained popularity throughout continental Europe, particularly in Switzerland, some regions of Germany, France, and the Low Countries.
Therefore the correct option is A.

A block of aluminum has a mass of 40.5 grams. If the density of aluminum is 2.7 g/mL, what is the
volume of this block?
Answer: 15 mL
Explanation:
Volume = Mass ÷ Density
= 40.5 g ÷ 2.7 g/mL
= 15 mL
∴ the volume of the block of aluminum is 15 mL.

Which of the following steps is required before biological processes can break down organic material in wastewater?
Aeration basins
Primary clarifiers
Filtration
Disinfection
The following steps required before biological processes can break down organic material in wastewater is Aeration basins and Primary clarifiers.
Water treatment refers to any technique that enhances the quality of water in order to make it suitable for usage by humans in homes and offices.
There are certain processes involved in the treatment of water. These includes:
screening and pumpinggrit removalprimary clarifiersaerationsecondary clarifiersFiltrationDisinfectionoxygen uptakeIn the screening and pumping process, materials and objects are removed from the entering wastewater using screening machinery. The extracted material is cleaned, crushed, and disposed of in a landfill.
In the grit removal, fine particle materials are eliminated from the wastewater.
Enormous circular tanks are known as clarifiers that receive the materials. Settled material acknowledge as primary sludge, is pushed to the tank's bottom, while the wastewater leaves from the top.
At the aeration stage, the wastewater receives the majority of its treatment. Pollutants are absorbed by microorganisms and turned into cell tissue, H2O, and nitrogen through biological breakdown processes.
The water treatment process was ended with filtration and disinfection to enable the water to be free from bacteria.
Therefore, we can conclude that the steps required before biological processes can break down organic material in wastewater is Aeration basins and Primary clarifiers.

Opinion: is our current water use sustainable? Why or why not?
Answer:
This actually depends, since most of our water is filtered (depending on where you live) then yes it is sustainable! But if our water wasn't filtered then no, it would not be sustainable. This is because of all the things that go into our water before it's filtered. We've got plastic, trash, dead fish and all that, in some cases sewer system drainage and a lot more that goes into the filtered water that we drink.
