The correct answer is to reduce harmful emissions.
Hydrogen is a chemical element with atomic number 1, this signifies that it exhibits one electron and one proton. Hydrogen gas (H2) is an odorless, colorless, highly combustible and tasteless gas. The hydrogen fuel refers to a zero-emission fuel that discharges no waste components, which can pollute the environment, this is the most likely reason that the US government made such an investment.
Answer:
The inheritance pattern is of sex-linked
Explanation:
Sex-linked traits are traits that are controlled by genes which are located on the sex chromosomes. Superscripts of the X or Y chromosome are written as the alleles for sex-linked traits chromosome.
In this case, since all of the male offspring have long tail fins, and none of the females possess the trait. Mating two of the F1 fish fails to produce females with the trait. The sex-linked gene that is on the Y chromosome and is possessed only by males is the type of inheritance pattern that occurs here because after mating the two F1 fish no female produced possess the trait.
CO2 is a normal waste that normally diffuse across placenta from embryo to the mother.
Answer:
1) c. five
2) a. lysine and arginine
3) g. two
4) d. four
Explanation:
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Basically, nucleotide comprises of the following parts;
1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.
2. A phosphate group.
3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.
The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;
I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.
II. Phosphate: this is the structural backbone that provides support to DNA.
Histones are a group of highly basic proteins that are mainly associated with deoxyribonucleic acid (DNA) in the nucleus of a living organism and then condense it to chromatin.
Histones include five main classes of relatively small basic proteins containing relatively large amounts of lysine and arginine. Nucleosomes are made of two each of four types of histones.
