Answer:

B.

Explanation:

The rise in the acids levels of the sea water is caused by the dissolve of CO2 in sea water which lowers the pH.The resultant unstable  compound(weak acid) formed is H2CO3.The latter dissociates to for HCO3 + CO3- These  reversible products are the buffers in the seawater that resists the fluctuation in the pH. The carbonate ions reacts with the high concentrations of  Ca + in the sea water, to form  the exoskeleton s of some  fauna.e.g.,Mussels.

A state is looking to reduce the cost of transportation, which uses 7.10×10^14 BTUs per year. Currently the cost of 10^6BTUs is
Ilia_Sergeevich [38]

Answer:

$ 284 million dollars

Explanation:

If the energy usage of all transportation is 7.10 × 10¹⁴ BTU per year, if their efficiency is to increase by 20%, The new energy usage will be (1 + 20/100)7.10 × 10¹⁴ BTU per year = (1.02)7.10 × 10¹⁴ BTU per year = 7.242 × 10¹⁴ BTU per year.

The energy saved is thus the difference 7.242 × 10¹⁴ BTU per year - 7.10 × 10¹⁴ BTU per year = 0.142 × 10¹⁴ BTU per year.

Since 10⁶ BTU costs $ 20.00, then,

0.142 × 10¹⁴ BTU costs 0.142 × 10¹⁴ BTU × $ 20.00/10⁶ BTU = $ 2.84 × 10⁸ per year = $ 284 million dollars

So the state saves $ 284 million dollars in one year

Which two globin genes are most divergent from each other? what is the percent amino acid identity between them?
tiny-mole [99]

Globin 1 and globin 2 genes of insects are understood to have diverged approximately 170 million years ago, through duplication, from a common globin gene ancestor. The two genes that code for haemoglobin have conserved regions; oxygen-binding and heme- regions. Globin 2 gene has lost the intron region that is still present in the globin 1 gene. The percentage divergence is 7.2% with 20 varying nucleotides.
