Answer:
This is true.
Explanation:
More commonly, an X chromosome will die and get replaced by a Y chromosome (all humans start off as females). When this occurs, the substitute Y chromosome causes changes in the zygote to occur; they begin developing male genitalia (i.e. penises, testicles, prostates, etc.).
Viscosity is a measure of a fluid's resistance to
flow
A: True
B: False
Answer:
Viscosity is a measure of a fluid's resistence to flow is true i believe
Viscosity is a measure of fluids' resistance to flow a correct statement. So the correct option is True.
What is viscosity?The measurement of a fluid's resistance to its own flow and any objects that may be inserted in it is called viscosity.
Viscosity is given by the symbol η (eta) and is defined as the ratio of shearing stress (F/A) and the velocity gradient of the flow of a liquid (dvx/ dy).
Velocity is also defined in the form of Newton’s equation which states that the shear force resulting is directly proportional to the applied force and it is inversely proportional to the viscosity.
The SI unit for velocity is Pascal. Second (Pa S).
The other form of viscosity is called kinetic viscosity which is the ratio of a fluid’s viscosity to its density. It is given by ν (nu). It is a measure of the resistance of a liquid against flowing when it is under the influence of gravity. The SI unit of kinetic viscosity is a square meter per second.
Therefore, the above statement is true.

DNA evidence analysis is an imperfect science. Provide two reasons why this may be the case.
For my Biomedical Science Class
Answer:
Not all DNA that was found at the scene has to be related to the scene.
Explanation:
Just because DNA was found at the scene, that doesn't mean that the person there is actually guilty. For example, in a case where person B is guilty, a strand of hair from Person A could be carried over to another scene on Persons B's clothing.
Answer:
Because DNA is more reliable than other forensics, scientists have shrugged off suggestions that it could fall victim to the vagaries of bias. But Dror noted that much DNA analysis involves interpretation. With interpretation comes subjectivity, and with subjectivity can come error. Only one-tenth of 1 percent of human DNA differs from one individual to the next and, although estimates vary, studies suggest that forensic DNA analysis is roughly 95 percent accurate.

The correct option is B
Explanation:
Dew is the water droplets found on objects outside of an enclosed/covered area in the morning.

In a chemical analysis of a sample of animal tissue, which element would most likely be found in the smallest quantity?
Answer:
Iodine
Explanation:
Iodine is needed by animals because the body's metabolic rate is controlled by the action of an iodine hormone, called thyroxine, which is secreted by the thyroid gland in the neck.
If the animal fails to supply enough iodine through food to be able to make a normal amount of this compound, then the thyroid gland enlarges or expands trying to create enough, resulting in a common type of goiter.
