Answer:  pathogen–host coevolution

Explanation:

A major driver of evolution is Reciprocal coevolution between host and pathogen. Rather than pathogen, one-sided adaptation to a nonchanging host, high virulence specifically favoured during pathogen–host coevolution. In all of the independent replicate populations under coevolution, the pathogen ( B. thuringiensis ) genotype BT-679 with known nematocidal toxin genes of C. elegans and high virulence specifically swept to fixation but only some of them go under one-sided adaptation,

so relative change in B. thuringiensis virulence was greater than the relative change in C. elegans resistance is due to the elevated copy numbers of the plasmid containing the nematocidal toxin genes .

For each of the formulas, classify the formula as either an empirical formula, a molecular formula, or both. NaHCO3 empirical mo
shutvik [7]

Answer:

Both

Explanation:

Baking soda is the common name of  sodium bicarbonate or sodium hydrogen carbonate. Both the empirical and molecular formula of sodium bicaronate is NaHCO3 .

Baking soda is soluble in water and has a molar mass of almost Molar mass: 84.007 g/mol.

If we look at molecular formula of NaHCO3, it has molar ratio of 1:1:1:3 and we can say that every thing in this molar ratio make whole mass as : 23g +1 g +12 g+48 g= 84 grams.

Since we know that empirical formula demonstrates the simplest ratio of elements present in a compound and molecular formula demonstrates the total molar ratio of each element in a compound, hence we see that its empirical and molecular formulas both are already simple because they have simplest ratio which cannot be simplified further.

Hope it help!

The wings of a bat and the wings of a bird are an example of convergent evolution. true or false
VARVARA [1.3K]

Answer:

Birds and bats have homologous limbs because they are both ultimately derived from terrestrial tetrapods, but their flight mechanisms are only analogous, so their wings are examples of functional convergence.
