Umnica [9.8K]

Answer:

All of these are correct

Explanation:

According to the question, marble is a rock formed from limestone, which in turn is also formed from Calcite. This shows that marble is a kind of metamorphic rock because a metamorphic rock is any rock that is formed by the alteration of other rocks caused by heat, pressure or chemicals etc. These changes that occurs in the previously existing rocks are called METAMORPHOSIS.

Hence, since marble is formed from limestone, it concludes that marble is a metamorphosed rock formed from a previously existing limestone rock. Also, since Calcite, a precursor of limestone that marble is formed from can be degraded by acids, both limestone and marble which are formed from it will also be dissolvable by acids.

How does diploidy help to preserve genetic variation? see concept 23.4 (page 498)?
mario62 [17]
Monoploid organisms reproduce asexually since they need to transmit all of their genetic material to their offspring. Diploid organisms, have 2 copies of their genetic material that differ slightly in their genes. Since the progeny gets half of the DNA from each parent, we have that new combinations can emerge; for example, if the mother is AA for some allele and the father aa, their offspring will be Aa, a new genotype. This might have different implications (for example, the recessive gene for thalassemia also provides resistance to malaria). Finally, during meiosis, there is also an event called crossover that increases the genetic variation of the offspring.

Airida [17]

Answer:

The correct answer is option Complex neuroendocrine response.

Explanation:

Hypothalamus is the thermostat of the body as it regulates and maintains body temperature by responding to external signals or stimuli and adjusts the body temperature in a close one to two degree of 98.6 degree.

The regulation involves a different type of endocrine hormones and thyroid gland and receptors that help in signaling the increase or decrease of body temperature it involves neurons and hormones.

Due to the response of thermoreceptors and hormones is known as the neuroendocrine response. Hypothalamus Involves two or more hormones and several steps it known as a complex response.

Thus, the correct answer is a Complex neuroendocrine response.

On a call to a​ crime-ridden area where drug abuse is​ common, you are sure that the current call for a patient with altered men
suter [353]
The answer is confirmation bias. This is the tendency to look for evidence that will confirm ones hypothesis and  ignoring anything else that does not lead to the hypothesis. In this situation confirmation bias is evident due to the fact that you look for anything that confirms your hypothesis and ignore anything else that does not point to drug abuse.
