A Refrigeration system helps keep foods fresh for a longer time and it also helps to keep the food from collecting bad bacteria.
The transmission of an impulse is made possible first by electric signals propagating within a neuron. Then, at the end of the axon called a synapse, chemical substances called neurotransmitters get released to transmit the message. These neurotransmitters then attach to chemical receptors in the following neuron.
Cyanobacteria had a role in the evolution of eukaryotic cell, more precisely their organelles. It has been shown that chloroplast, cell organelles found in some eukaryotic lineages, which are specialized in performing the photosynthesis evolved from cyanobacteria through the process called endosymbiosis. In this process, photosynthesizing cyanobacteria was engulfed in some ancient eukaryotic cell. Eukaryotic cells have evolved from the endosymbiotic events.
<span>By producing and releasing O2 (as a byproduct of photosynthesis), cyanobacteria are thought to have converted the early oxygen-poor, reducing atmosphere into an oxidizing one. This caused the Great Oxygenation Event which dramatically changed the Earth's life forms and led to the formation of multicellular organisms.</span>
Answer: Is most likely to result from reduced ATP levels.
Explanation:
Dichlorodiphenyltrichloroethane (DDT) is a colorless, odorless, tasteless, crystalline compound. It is an organochloride. It is used as an insecticide. It is associated with damage of biodiversity and several human and animal health complications.
In human males DDT is associated with decrease in fertility. As it results in low sperm count, negatively affects the sperm motility and synthesis.
The uncoupling process will reduce ATP synthesis in the mitochondrial cells of the sperms. This may lead to low sperm motility in the vaginal canal of the female after the insemination process. Thus this will reduce the male fertility.
