Explanation:
Cancer can kill when it invades essential organs, like your liver, lungs, or brain, and stops them from functioning properly. These complications could be due to primary cancer that starts in an essential organ, such as brain cancer. Or it could be cancer that has metastasized from one area to another.
Answer:
The correct answer is "Histones in general have a net negative charge that allow them to bind to DNA. Acetylation of histones, decreases their positive charge and weakens the histone-DNA interaction".
Explanation:
Histone acetyltransferases (HATs) are regulators of gene activation and deactivation, achieved by the transference of an acetyl group from acetyl-CoA to histones. HATs function by the premise that histones in general have a net negative charge that allow them to bind to DNA. Acetylation of histones, decreases their positive charge and weakens the histone-DNA interaction. Therefore, most of the times histone acetylation increases gene expression, because the acetylated gene is free from the histones and is able to be encoded.
Answer:
The Klinefelter syndrome is caused by the presence of one extra X chromosome (i.e., XXY males). Developmental limitations of this genetic disorder include: reduced muscle mass, neurodevelopmental problems, hypogonadism, etc. Abnormal chromosome numbers (known as aneuploidies) are usually caused by the nondisjunction of homologous chromosomes during Anaphase I or the nondisjunction of sister chromatids during Anaphase II
Explanation:
The Klinefelter syndrome is the most common sex chromosomal disorder in males, which is caused by the presence of an extra X chromosome (i.e., males with a XXY karyotype). This genetic disorder has many effects on development, including small testes (hypogonadism), weaker muscles, longer arms and legs, larger breasts than normal, infertility, immature development of secondary male sex features, cognitive problems (e.g., speech and language delays), etc. A chromosomal disorder occurs when chromosome pairs or chromatids fail to separate during meiosis, thereby producing cells (gametes) with more or fewer chromosomes than normal, a phenomenon known as aneuploidy.
Answer:
It provides more power in the form of pressure.
Compared to the open circulatory system, the closed circulatory system operates with much higher blood pressure, though it is said to be more efficient considering that it uses much less blood for even faster and higher levels of distribution.
Explanation:
It would disolve. after the ethanol entered the plasma membrane solevant enters the lipids and dissolves
