Answer:
Any process that involves active transport most often involves the expenditure of energy in the form of ATP hydrolysis.
Explanation:
Active transport in cells is a form of transport which involves the transport of solute molecules across a membrane against a concentration gradient using energy provided from some chemical reaction occuring in the cell.
Active transport is an endergonic (energy-requiring) process and therefore, must proceed only when coupled to an exergonic (energy-releasing) process such as the breakdown of ATP, an oxidation reaction, absorption of sunlight, etc.
In many instances in cell, such as the Na/K pump, ATP hydrolysis is the the common exergonic reaction to which active transport is coupled to.
Answer:
D. 6 CO 2 , 6 H 2O , and sunlight
Explanation:
The reactant are the substances are going under a reaction. They are the "items" needed for a product to form. In which in this case, 6 CO 2 , 6 H 2O , and sunlight are needed to make C 6H 12O 6 + 6 O 2
.
The answer is D
The nitrogen bases adenine, thymine, cytosine and guanine code for the amino acid sequence in the protein
Answer:
The correct answers are A, B and D. The Clean Air Act was important because it emphasized cost-effective methods to protect the air; encouraged people to study the effects of dirty air on human health; and created a regulation that makes any activities that pollute the air illegal.
Explanation:
The Clean Air Act is a federal federal law designed to control air pollution nationwide. The Environmental Protection Agency (EPA) is required to develop and enforce the regulations to protect the general public from exposure to air pollutants that are known to be dangerous to human health. The 1963 law established a basic research program, which was expanded in 1967. The main changes to the law, which require regulatory controls of air pollution, were promulgated in 1970, 1977 and 1990.
The 1970 amendments significantly expanded the federal mandate by demanding broad federal and state regulations, both for fixed sources of pollution (industrial) and mobile sources.
In 1990 provisions were added to deal with acid rain, depletion of the ozone layer and toxic air pollution, and a program of national permits of fixed sources was established. Also new requirements were established for the reformulation of gasoline, the adjustment of Reid vapor pressure (RVP), which measures the volatility of gasoline; and the norms to control the evaporation emissions of the gasoline.
The Clean Air Act is important because it was the first important environmental law in the United States to include a disposition regarding citizen demands. Numerous local and state governments have promulgated similar laws, either the execution of federal programs or to fill important loopholes at the local level in federal programs.
A model organisms is a species that has been widely studied, usually because it is easy to maintain and breed in a laboratory setting and has particular experimental advantages. model organisms are non-human species that are used in the laboratory to help scientists understand biological processes.
