The Clean Water Act (CWA) establishes the basic structure for regulating discharges of pollutants into the waters of the United States and regulating quality standards for surface waters. The basis of the CWA was enacted in 1948 and was called the Federal Water Pollution Control Act, but the Act was significantly reorganized and expanded in 1972. "Clean Water Act" became the Act's common name with amendments in 1972.

The genetic fault that usually causes colour vision deficiency is passed on in what's known as an X-linked inheritance pattern.

This means:

1) it mainly affects boys, but can affect girls in some cases

2) girls are usually carriers of the genetic fault – this means they can pass it on to their children, but do not have a colour vision deficiency themselves

3) it's usually passed on by a mother to her son – the mother will often be unaffected as she'll normally just be a carrier of the genetic fault

4) fathers with a colour vision deficiency will not have children with the problem unless their partner is a carrier of the genetic fault

5) it can often skip a generation – for example, it may affect a grandfather and their grandson

6) girls are only affected if their father has a colour vision deficiency and their mother is a carrier of the genetic fault

When Gregor Mendel crossed a tall plant with a short plant, the F1 plants inherited.

lys-0071 [83]

<h2>Answer:</h2>

a. one allele from each parent

<h2>Explanation:</h2>

An allele in biological sciences is one of the possible forms of a gene that it can inherit. Most genes have two alleles, a dominant allele and a recessive allele. When Gregor Mendel crossed a tall plant with a short plant, the F1 plants inherited an allele for tallness from the tall parent and an allele for shortness from the short parent.

Describe the process of diffusion, including a detailed explanation of equilibrium.

vivado [14]

<span>Diffusion is a process of desintegration or disolution. Equilibrium is where all states are equal. Equilibrium works here too, but too many invisible forces drag it into chaos. Equilibrium means less invisible chaos.</span>

Which molecules within the cell are responsible for carrying genetic information carbohydrates proteins lipids nucleic acids?

sukhopar [10]

Answer: Nucleic acids

Explanation:

Nucleic acids are biologically occuring polynucleotides in which the nuclotides residues are linked in a specific sequence by phosphodiester bonds.

The two types of nucleic acids are DNA which is double stranded and serves as the usual carrier of genetic information while RNA which is single stranded serves a carriers of genetic information in some viruses only.
