Explanation:
GMO foods have been known to cause many side effects and some say that it even has the chance of causing cancer.
The people who are not concerned about these side effects, are the people who are making a large profit off of selling these engineered foods.
Answer:
A lot of factors cause genetic variation in a population. The root of all genetic variation is mutations, which occur randomly.
A lot of genetic variation in fact results during meiosis, the process by which gametes (sex/reproductive cells) are formed. The 3 main ways are crossing over, independent assortment of chromosomes, and random fertilization. Crossing over occurs during Prophase I of meiosis, in which genetic material is exchanged between nonsister chromatids of homologous chromosomes. Independent assortment refers to the following: When cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other. Random fertilization is where any sperm can fertilize any egg cell. The many combinations of eggs and sperms mean variation.
Another source of genetic variation include gene flow. Gene flow is where populations have their members enter other populations (migration), influencing the gene pool of populations. This source is more controversial, however.
Random mating can also increase genetic variation.
Answer: A. endocarditis
Explanation:
Endocarditis is the inflammatory process of the endocardium, especially that located in the heart valves. There are several factors causing endocarditis, the most frequent and lethal being endocarditis caused by infectious agents. The most common mechanism is endothelial injury due to blood flow turbulence, be the one generated by a defective valve (rheumatic, bicuspid aortic valve, dysfunctional valve prosthesis), or by any congenital anomaly that causes flow turbulence (interventricular communication, obstructive hypertrophic cardiomyopathy, aortic coarctation).
The most common site of injury, and therefore the most frequent site of vegetation formation, is at the closing line of a valve, usually on the atrial surface of the atrioventricular valves or on the ventricular surface of the ventriculoarterial valves. With the endothelial lesion occurs the formation of a sterile thrombus, which can be colonized by bacteria that multiply there, turning the thrombus into vegetation. These vegetations are avascularized, making the treatment of endocarditis difficult due to the low access of antibiotics to microorganisms.
Answer:
A dog pants in the heat to control its body temperature. Panting is a mechanism of homeostasis that dogs use for regulation .
Electronegativity.
If the difference in electronegativity for the atoms in a bond is greater than 0.4, we consider the bond polar. If the difference in electronegativity is less than 0.4, the bond is essentially nonpolar.
