Short Answer: As the comments mention, this is a hot topic for pseudoscientists to use as a selling point for their supplements. There is limited evidence that dietary acid intake significantly alters bone resorption, especially in the setting of normal renal function. This paper should answer all of your questions (emphasis mine): Frassetto, Banerjee, ...

I am reinforcing the statement made by the previous answer. Yes, histones are the most abundant proteins in the chromosome (Ohta et al. 2010); they can contribute up to ~38% of the chromosome mass. Other abundant chromosomal proteins include toposiomerase-IIα and condensin-I (SMC proteins). Apparently many non-chromosomal proteins i.e. proteins that ...

Barden et al (2017) have discovered an extinct species of ant (hell ant) that was alive 95 million years ago that had naturally occurring metal mandibles. Mandibles on ants are essentially the same as fangs on spiders or teeth on humans.

It is likely a volatile organic compound (VOC) that is released as a by-product of microbial metabolism, although microbes can also produce some inorganic compounds, such as hydrogen sulfide (rotten egg smell). It could be any of a number of compounds, depending on the microbial species and the environmental conditions. The only relevant paper I could find ...

Your guess is correct: glucose is not the sole source of energy in the cell! While cellular respiration is the classic mechanism for energy production (in the form of ATP) in the cell, there's another process that's equally important and a little less well-known: beta oxidation. Beta oxidation is how fats and other lipids in the cell can be broken down to ...

For grasses leaves tend to be inedible due do with the high quantity of silica deposited in the leaves to form structures known as phytoliths Wikipedia. While this has been shown to inhibit digestion by insects (Hunt et. al., 2008, Massey et.al., 2006), I'm not aware of any studies on how this affects digestibility for humans. There are however anecdotes ...

Nutrient content of lettuce and grass can be similar. According to USDA.gov, 100 g of green leaf lettuce contains: Protein = 1,4 g Digestible carbohydrates = 1.5 g Calcium = 36 mg Potassium = 194 mg Magnesium = 13 mg Fiber (cellulose or similar) = 1.3 g According to Feedipedia (see Nutritional Tables), 100 g of Bahia grass contains: Protein = 3.5 g ...
