Answer:
Solar waves with wavelengths between 160 and 400 nanometers are known as ultraviolet rays and carry higher levels of energy than sunlight. Solar waves with wavelengths between 780 and 1,500 nanometers are known as infrared rays and carry lower levels of energy than sunlight.
Answer:
No, CREs usually don't account for differences in gene expression levels.
Explanation:
<em>Cis</em>-regulatory elements (CREs) are non-coding DNA regions that regulate adjacent gene <em>transcription</em>. They usually do it by binding to transcription factors. They are in charge of influencing the rate of which transcription occurs, and less with how much a gene is expressed. On the other hand, trans-regulatory elements are DNA sequences that encode for upstream regulators that can modify or regulate <em>gene expression levels</em>.
Therefore, cis elements are not really in charge of expression levels, mostly transcription rates of single genes, rather. Trans elements are more involved in expression levels.
Spermatogenesis is the process in witch spermatozoa are produced from male primordial germ cells by way of mitosis and meiosis.
Oogenesis is the process by which the female gametes, or ova, are created.
