We humans are affecting the global food supply because of climate change. As you know the world is super polluted and threat of climate change is the collapse of food systems: Other threats — flooding, storms, forest fires — may be more sudden and severe in certain regions, but disruptions in food supply will affect virtually everyone.
Answer:
c. Glycolysis evolved in an oxygen-rich environment.
Explanation:
Glycolysis is the pathway that breaks down glucose into two molecules of pyruvate. It is a common pathway that is performed by both aerobic and anaerobic organisms. In aerobic organisms, glycolysis is followed by Kreb's cycle and electron transport chain. In anaerobic organisms, alcohol or lactic acid fermentation regenerate the NAD+ which is required to sustain glycolysis.
Therefore, glycolysis is independent of oxygen availability and can be performed under both aerobic and anaerobic conditions. This means that the pathway of glycolysis evolved under anaerobic conditions.
Answer: A
Explanation: Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow, and lets them get rid of waste products. This table shows examples of substances required by cell and associated waste products.
Answer: C) Turbine
Explanation: Crude oil is turned into usable forms of energey by a Combustion Turbine. Hope this helped!
Answer:
B. AUU CGC AUC UUG AAC
Explanation:
<em>According to the rule of base pairing in DNA, the pyrimidine bases always pair with purine bases. Specifically, adenine (A) always pair with thymine (T) while Guanine (G) always pair with cytosine (C). In RNA, thymine is replaced by uracil (U).</em>
Hence, TAA GCG TAG AAC TTG will give
AUU CGC AUC UUG AAC.
The correct option is B.
