There are different kinds of light, and they vary by energy, frequency, and wavelength. Energy and frequency go together, so the light that has high frequency has high energy, and vice versa. Frequency and wavelength are opposites, so as frequency increases, wavelength decreases. The light that we see from stars is visible light, which is only a very small part of the different possible kinds of lights. Our eyes are only able to see within a small range of wavelengths.

Choose all of the following that are examples of SECONDARY SUCCESSION? a. wild fire b. volcanic eruption c. glacier melting d. f
inn [45]

Answer:

i think it would be A for wild fire, D for flood and E for Tsunami

Explanation: wild fire are one of the most common ways for a secondary succession that can bring change when the environment is disturbed or damaged. For instance, by allowing fast-growing plants to grow and provide a source of food and shelter for many animals to use and eventually draw them back into the ecosystem. Both flooding and tsunamis help push older organisms and other stuff from the environment to create for room for other plants and animals to come and keep the ecosystem healthy and ongoing.

i hope this can help you with your work mate!

Explain the purposes of gene expression studies. Describe the use of DNA microarray assays and explain how they facilitate such
denis-greek [22]

Answer:

Both gene expression and DNA micro array study about the expression of gene during different stages of development.

Explanation:

The main purpose of gene expression studies is to determine the level of mRNA expressed at different stages of transcription in a tissue or at different stages of cellular development. If a gene is not “ON” during synthesis of RNA and protein, then the desired proteins are not produced. Such studies allow us to turn on such genes.  

DNA microarray  assays easily identify and determine the network of gene expression across the entire genome. The common application of DNA microarray include – mutation analysis and detection, assessment of gene cop, immunoassays etc.

In ____, several sets of alleles control the phenotype and each dominant allele present codes for a product which has a quantita
tatuchka [14]

Answer:

Polygenic inheritance

Explanation:

Polygenic inheritance occurs when a genetic trait is regulated by more than one genes. All the alleles of these genes together determine the phenotype of the organism for the polygenic trait. Here, the phenotype is regulated by the total number of dominant alleles for all the genes that regulate a polygene trait.

For example, human skin color is a polygenic trait. The final phenotype depends on the total number of dominant alleles of all the genes that regulate the skin color in human.
