What are the drops of water that form on cool surfaces during the night called?
A. Snow
B. Dew
C. Steam
D. Rain
Answer:
The correct option is B
Explanation:
Dew is the water droplets found on objects outside of an enclosed/covered area in the morning. Dew occurs as a result of condensation of moisture in the cold atmosphere (at night) which is converted to liquid when it touches objects of higher thermal energy; converting the water in the moist air into water droplets known.
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.

What is crossing over in meiosis and how does it ensure genetic diversity?
Answer:
When homologous chromosomes form pairs during prophase I of meiosis I, crossing-over can occur. Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. ... It is obviously another source of genetic variation in offspring.

describe some of destructive action of microbes
Answer:
A microbe is a small living thing too tiny to be seen by the naked eye and includes bacteria, fungi and viruses. Among their destructive actions is causing diseases in human beings and their livestock or plants, destruction of food by causing decomposition which might lead to hunger and other related calamities. Despite this destructive consequences, microbes are also known to have advantageous actions like helping in sewerage treatment, microbes found in the gastro-intestinal tract help in maintaining a good environment for digestion to take place. Microbes also help in ecological balance by causing decomposition of dead matter hence conserve the environment.

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.

If more carbon dioxide was made
available to a plant, what would be the
effect on the rate of photosynthesis?
A. The rate would be unaffected.
B. The rate would increase.
C. The rate would decrease.
Answer:
B. The rate would increase.
Explanation:
Increased carbon dioxide concentration increases the rate at which carbon is absorbed into the carbohydrate in an independent reaction, so the level of photosynthesis usually increases.

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.

The bacteria in a colony are unable to perform conjugation. How would this hurt the bacterial colony's chance for survival?
A. The bacteria would lose all their RNA.
B. The colony could not produce bacteriophages.
C. The colony would have less genetic variation
D. The bacteria in the colony could not reproduce.
The colony would have less genetic variation. The Bacteria in the colony would be too genetically similar
The bacteria living in a colony is aunable to perform the conjugation as they have less chances of survivial due to the colony is less genetically divere. Thus the option C is correct.
What is conjugation ?This is a process wherein organism of the same species like the bacteria, exchange the nuclear mating materials during a temporary union and are capable of transferring one consent form from one organism to another. Thus the lack of genetic variation will lead to fewer chances of species survival.
