Explanation:

Chronic sleep deprivation has been linked to a greater risk of obesity, Type 2 Diabetes, dementia, depression, cardiovascular disease, and cancer. There has also been research to show that insufficient REM sleep may cause migraines.

Answer:

The correct answer is "altering the equilibrium of ecosystems".

Explanation:

Ecosystem have a very complex and sometimes intricate equilibrium. Each species in an ecosystem have a role in the food chain, therefore, if humans affect the behavior of one species, undoubtedly, another species will be affected. In this case, insect populations are increasing as a result of birds modifiying they migratory behavior due to the presence of discarded food in the landfills. Most likely the increased insect populations will affect the plants population as well, creating a series of events that alter the equilibrium of the ecosystems.

patriot [66]

Answer:

The best estimate of population density of this particular Octopus spieces is (TOTAL POPULATION OF THE OCTOPUS)/(TOTAL AREA OF LAND)

Population density = (15/6) Octopus per hectare

Explanation:

To estimate the population density of a spiece in a particular area of land, we count the total number of the specie in the area and divide the total number by the area of the sampling region.

Above, the marine ecologist counts the number of octopus in three different intertidal regions that are each two hectares. The octopus counts are 7, 2, and 6 respectively.

Therefore, the total number of Octopus is 7 + 2 + 6 making 15. The regions are 2 hectares each. Since there are three of the intertidal regions, the total area is 2 x 3(6 hectares).

Therefore, Population density = (15/6) Octopus per hectare

What is the biological significance of genetic diversity between populations? What is the biological significance of genetic div

mrs_skeptik [129]

Explanation:

<u>A) Genes for traits conferring an advantage to local conditions make microevolution possible.</u>

For example, Galapagos finches show variation in beak sizes and shapes related to their niches and available food source; the finches developed adaptations to their environment. Their specialized beaks allow them to adequately exploit the available resources, by utilizing the more abundant food source.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.

Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell. Crossing over, independent assortment, and random fertilization ensure genetic variation.

This variation refers to the genetic characteristics present within a species; they form new traits called alleles, which may confer adaptations that increase the fitness of a species, along with ensuring survival by conferring an advantage.

Additionally, natural selection, mutation, genetic drift and gene flow lead to microevolution; over time, this is seen as changes to allelic frequencies within a population

What definition of realism in theater?

Rashid [163]

Realism in the theatre was a general movement that began in the 19th-century theatre, around the 1870s, and remained present through much of the 20th century. It developed a set of dramatic and theatrical conventions with the aim of bringing a greater fidelity of real life to texts and performances.
