Answer:
The correct answer is (e) None of these statements about metabolism is incorrect. Although chemical reactions take place outside of living organisms, regulated metabolic pathways are unique to living organisms. ... Finally, metabolism utilizes water to break bonds in macromolecules through a process known as hydrolysis.8. Identify THREE structures found in plant cells but not in animal cells

Recombination (crossing over) during prophase I of meiosis occurs when:
Answer:
meiosis before tetrads are aligned along the equator in metaphase I.
Explanation:
When chromatids "cross over," homologous chromosomes trade pieces of genetic material, resulting in novel combinations of alleles, though the same genes are still present. Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I
What is recycling? How does it help in management of hazardous waste?
Answer:
Recycling is the process of converting waste materials into new materials and objects.It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions.
When hazardous wastes are recycled, less energy is needed to obtain raw materials and to manufacture products. When energy demand decreases, fewer fossil fuels are burned and less GHGs are emitted into the atmosphere, which can help lessen the impacts of climate change and decrease air pollution.
Answer:
The process of converting waste materials into reusable material is called recycling.When hazardous wastes are recycled, less energy is needed to obtain raw materials and to manufacture products. ... This means less need for hazardous waste landfills and incinerators, as well as a decrease in energy used for those systems, which leads to less pollution
The use of marijuana while drinking alcohol
lowers the BAC of the driver causing some impairment of driving ability
does not affect driving ability
may affect driving ability if both substances are taken in abundance
impairs driving beyond that usually related to the BAC of alcohol

(a) increase
(b) decrease
(c) remain the same
Can someone help me, my paper is due tonight.
Describe solution concentration outside the cell in terms of hypotonic, hypertonic and isotonic.
Answer:
see below
Explanation:
Hypotonic solution is a very dilute solution to the more concentrated solution. Hypo means under . A solution with a lower concentration of solutes than the cytoplasm of a cell, that solution is hypotonic to the cytoplasm. The cell expands as water moves in.
Hypertonic solution is a more concentrated solution to cytoplasm. Hyper means above. A hypertonic solution has higher concentration of solutes than the cytoplasm of the cell. The cell shrinks as its cytoplasm loses water.
Isotonic solution is when two solutions of equal concentration are separated by a semi permeable. Iso means equal. Therefore, in isotonic solutions, water movement out of a cell balances the water movement into it. Cells in the body are usually surrounded by a fluid. The cytoplasm in the cell is usually isotonic to the fluid outside the cell. Hence, no net gain or loss of water by cells.
So, basically, if a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.
