Answer: Option B

Explanation:

If a statement is given which states that an object is 3000 light years away then it states that the object that we can see now by our eyes must have arrived 3000 years before to reach our eyes.

Light years is generally used to measure the distance between the earth and heavenly bodies. It takes light years for any object's light to reach the earth.

It is generally used for very long distances that cannot be converted into kilometers or meters.

Answer AND Explanation:

FACTORS THAT CAUSE GENETIC VARIATIONS

Crossing over. At the chiasmata during prophase I of meiosis, breakage may occur and exchange of genetic information may take place. New gene combinations which result in variations.
Independent assortment. The arrangement of homologous chromosomes at the equator of the spindle during metaphase of the first meiotic division is random. These homologous chromosomes segregate into different daughter cells which contain different genetic combinations which brings about variation
Fertilisation permits parental genes to be brought together in different combinations. This is the cause of variations in members of the same family.
Mutation is the spontaneous change in the genetic makeup of an organism. These changes may be inherited by the offspring therefore beginning variation.

Gala2k [10]

Answer:

The reason why there is so much diversity of life, despite the fact that DNA is the same for all living things, the pairings are always the same and there are only six components that make up the DNA, is that sequences of base pairs are different.

Explanation:

DNA is the molecule that contains all the genetic information, whose structure consists of four nitrogenous bases, adenine, guanine, thymine and cytosine, plus deoxyribose and a phosphate group. This DNA molecule constitutes the basis of life and inheritance of all living beings.

The nitrogenous bases of DNA are found in a number and specific sequences, which determine the proteins and biomolecules that must be synthesized in the cells.

What makes different types of living beings and diversity of life is the length of the DNA and the sequence of bases that form part of each molecule.

The other options are not correct because:

The sugar component of DNA is always the same, not different.
Organisms always use DNA in the same way.
The DNA molecule is always the same.

Why do you think gene therapy is such a promising field for this disease?

Alekssandra [29.7K]

Answer:

Gene therapy replaces a faulty gene or adds a new gene in an attempt to cure disease or improve your body's ability to fight disease. Gene therapy holds promise for treating a wide range of diseases, such as cancer, cystic fibrosis, heart disease, diabetes, hemophilia and AIDS.
