So let’s substitute that into the
third equation and solve for B. B = H + T B = 9 + (9 + 1/2B) B = 18 + 1/2B Then
subtract 1/2B from both sides: 1/2B = 18 Multiply both sides by two: B = 36 Now
we know the value of B and the value of H. Substitute this back into the second
equation and solve for T. T = H + 1/2B T = 9 + (1/2)36 T = 9 + 18 = 27 Step 4:
Plug all values of H, T, and B into the final equation. Total length of fish =
H + T + B Total length of fish = 9 +27 + 36 = 72.
The answer is R. The structure of singulair (montelukast), a medication used to manage asthma, the absolute absolute configuration of the chirality center is r and not s. Montelukast is aeukotriene receptor antagonist used to relieve symptoms of seasonal allergies.and used <span>for the maintenance treatment of asthma.</span>
The correct answer is plants with seeds are not dependent on water for reproduction.
<span>
Seeds contain a diploid embryo that will germinate into a sporophyte and thus it has a role to nourish and protect that embryo. The main advantage of the seeds is that it has several layers of hardened tissue which prevent desiccation and that allow them to live and reproduce without water. </span>
The advantage for the reduced gametophytes in seed plant is that they gain nutrients from the sporophytes
Gametophytes are microscopic and have capacity to develop from spores retained in the sporangia of parental sporophyte. This kind of arrangement protect developing gametophyte from environment stress which enable it to gain nutrient from sporophyte.
To safeguard against ground water contamination, sanitary landfills are lined with plastic and clay. Ground water is the water beneath Earth's surface in soil pore spaces and in the fractures of rock formations.Water that falls as precipitation flows along the surface of the ground. This surface water infiltrates into the ground surface and is held in soil pore spaces and in the fractures of rock formations. To gain access to this water sources it requires digging or drilling the ground and into an aquifer.
