Answer: Yes, because Congress may adopt laws regulating navigable waters.
Explanation:
It should be noted that municipalities using copper-based paint on their intake pipes can successfully be prosecuted for violating the federal law because Congress may adopt laws regulating navigable waters.
Under the Supremacy Clause, when the action of either the state government or the local government conflicts with the federal laws which are deemed valid, then such cities can be prosecuted.

What is ecological succession?
A. Change that happens over time in an ecological community
B. A way a life
C. One person giving another person power
Answer:
A. Change that happens over time in an ecological community
Explanation:
Ecological succession is the change that happens over time in an ecological community. So, option (A) is the answer.
Answer:
A. Change that happens over time in an ecological community
Explanation:
Ecological succession is the gradual process by which ecosystems change and develop over time. Nothing remains the same and habitats are constantly changing.
There are two main types of succession, primary and secondary.
Primary succession is the series of community changes which occur on an entirely new habitat which has never been colonized before. For example, a newly quarried rock face or sand dunes.
Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. For example, after felling trees in a woodland, land clearance or a fire.

1.DNA is a molecule composed of two chains in form a ____________ compose by______________, ____________ and pentose. And the structure and function of genes.
Answer:
DNA is a molecule composed of two chains in form of a DOUBLE HELIX compose by ORGANIC NITROGEN CONTAINING BASE, PHOSPHATE GROUPS and PENTOSE.
Explanation:
Nucleic acids are found in all living cells. They are composed of strands made up of repeating units called nucleotides. Each nucleotide consists of
--> a five carbon sugar( PENTOSE)
--> a phosphate group
--> an organic nitrogen containing base: adenine, guanine, cytosine or thymine.
The two types of nucleic acids include:
--> Deoxyribonucleic acid ( DNA) and
--> Ribonucleic acid ( RNA)
Deoxyribonucleic acid ( DNA) is found in chromosomes located in the nucleus of cells.
STRUCTURE OF DNA
The DNA molecule consists of two strands that curve spirally to form a double helix structure. The strands are held together by hydrogen bonds between the base side arms. Each base on one strand will only pair with a specific base on the other strand: hence guanine will only pair with cytosine and adenine with thymine.
FUNCTIONS OF DNA
It stores the organism's hereditary traits and directs the day to day metabolic activities of each cell in the organism.

Which label belongs in the region marked X?
involves changes in temperature
has a constant volume
shows an inversely proportional relationship
does not describe pressure changes
Answer:
Shows an inversely proportional relationship.
Explanation:
The Boyle's law belongs in the region marked X whereas the other circle belongs to Charles law. There is inverse relationship between the two circles or these two laws because in Boyle's law, temperature is constant while on the other hand, in Charles law pressure is constant instead of temperature. In Boyle's law, pressure of a gas is inversely with its volume whereas in Charles law, the volume of a gas is directly proportional to its absolute (Kelvin) temperature.

What is viruse ?A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898, more than 9,000 virus species have been described in detailof the millions of types of viruses in the environment.Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. The study of viruses is known as virology, a subspeciality of microbiology.
When infected, a host cell is often forced to rapidly produce thousands of copies of the original virus. When not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent particles, or virions, consisting of
(i) the genetic material, i.e., long molecules of DNA or RNA that encode the structure of the proteins by which the virus acts;
(ii) a protein coat, the capsid, which surrounds and protects the genetic material; and in some cases
(iii) an outside envelope of lipids. The shapes of these virus particles range from simple helical and icosahedral forms to more complex structures. Most virus species have virions too small to be seen with an optical microscope and are one-hundredth the size of most bacteria.
