The estimated energy requirements is 490 kilocalories per day.
For 4-6 months infants EER(kcal/d) = (89 x Wt [kg] - 100) + 56 (89x6 kg -100) + 56 (534-100) + 56 434+56 = 490
Answer:
stromatolites
Explanation:
Stromatolites or stromatoliths are layered mounds, columns, and sheet-like sedimentary rocks that were originally formed by the growth of layer upon layer of cyanobacteria, a single-celled photosynthesizing microbe. Fossilized stromatolites provide records of ancient life on Earth.
The answer is C barriers around mating
Viruses can only replicate with in a cell or living tissue applies to a viral infection.
Viral infections are infections that are caused by viruses. Viruses are microscopic organisms that contains a core of genetic material (DNA or RNA) enclosed by a protein coat. Viruses are not made of cells and they are very tiny and smaller than bacteria. Viruses require a living cell (host organism) to replicate and produce other viruses similar to them. Viral infections cannot be treated with antibiotics, antiviral medicines are used instead. Examples of viral infections include; common cold, flu, smallpox, HIV/AIDS and Ebola.
Electrons are brought to the electron transport system by the oxidation of NADH and FADH2.
The electron transport chain is a group of proteins located within the inner membrane of the mitochondria which transport electrons. Electrons are passed from one member of the transport chain to another in a series of redox reactions, forming a proton gradient which is then used for ATP production.
NADH and FADH2 are reduced electron carriers which are oxidized into NAD+ and FAD near the beginning of the electron transport chain.
