Because we can't take in light energy directly, we consume plants. Plants convert light energy into chemical energy through the process of photosynthesis. So when we eat plants, we get the chemical energy stored in the carbohydrates, which fuels all our physical activity.
C because the paragraph
---"The internet does not claim to operate by any particular ethical standards, still less high ones. Some have called it a ‘wild west’ but I would prefer to use the term ‘ethical vacuum’,” he wrote.
----"Bloggers and others who write on public topics can act with impunity, he states. Newspapers, however, already have ethical codes and promise a quality product. "
Answer
The phrase internet is used in both paragraphs which is related to technology.

Answer:
The Answer is, B, C, And E. I just took it on USATESTPREP.
B) G3P can be used to form the backbone of triglycerides. Glycerol combines with fatty acid tails to form lipids.
C) Two G3P molecules can be combined through anabolic processes to form glucose, a six-carbon sugar required by cells.
E) G3P can be used in to synthesize amino acids, which contain a central carbon, a carboxylic acid group, and a variable R group. These amino acids can then combine to form proteins.
Both, actually. They both add up to 46 chromosomes. If you have less than 46, you will come out with Autism. Hope this helps!
Answer: Tightly wound chromosomes, composed of DNA, must unwind before replication. Cell replication splits a cell into two parts, both of which become new, fully functioning cells. Before this can happen, however, cells require a full complement of DNA for each of the new daughter cells that will form as a result of the split. Because of this, DNA makes a copy of itself in a process known as replication during interphase, a stage that occurs before cells divide.
Cell Phases: Mitosis is the process by which parent cells each divide into two identical daughter cells. However, this majority of the cell's time is spent in interphase, during which it performs normal metabolic functions necessary for the organism, such as manufacturing protein. DNA occurs during the S phase of interphase, sandwiched between the G1 and G2 phases. The cell uses checkpoint signals to ensure at the end of G1 that it is big enough to replicate and at the end of G2 to determine whether or not DNA replication has succeeded. If so, the cell can undergo mitosis, at which point DNA winds up tightly for easy transport during the process.
DNA Replication: Replication begins with DNA unwinding and unzipping, its two strands coming apart. While only one side is the “correct” code, containing the actual genetic information used to build the organism’s proteins, both can be the base for a new strand of complete DNA. The enzyme DNA polymerase matches up each base with the correlating base: adenine with thymine and guanine with cytosine. When each pre-existing base has been matched to a nucleotide, which also contains the sugar and phosphate of the DNA’s backbone, the strand is complete.
