The answer is 22.5 lb/gal.
The density of a liquid is quotient of mass and volume: D = m/V. The unit of the density is pound per gallon (lb/gal)
The density is unknown: D=?
But, we have:
mass: m= 90 lbs
volume: V = 4 gals
Do, the density of a liquid is:
D = 90 lbs / 4 gals
D = 22.5 lb/gal
Answer:
Environmental Science is an interdisciplinary course covering a wide variety of topics including biology, physics, geology, ecology, chemistry, geography, astronomy, meteorology, oceanography, and engineering. The course also considers ways in which human populations affect our planet and its processes. Of special emphasis is the concept of sustainability as a means of using resources in a way that ensures they will always be around us. The unifying concepts that tie the different areas of environmental science together are as follows:
Science provides a way to learn more about the world and influences how we understand it.
Energy conversions underlie all ecological processes.
The Earth is one interconnected system.
Humans change natural systems.
Environmental issues have a cultural and social context.
Human existence depends in part on increasing practices that will achieve sustainability
Explanation:
Answer: In biology, a gene is a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. Genes and DNA are different..... DNA is the molecule that is the hereditary material in all living cells. Genes are made of DNA, and so is the genome itself. A gene consists of enough DNA to code for one protein, and a genome is simply the sum total of an organism's DNA.
Hope this helps..... Stay safe and have a great day/night!!! :D
