Answer:
Environmental factors include factors in the surroundings that can have an impact on humans. This includes climate, temperature, population density, pollutants, etc.
Explanation:
A way that scientists can analyze and interpret data to identify the potential environmental factors is by analyzing the distribution or variation in traits across a population.
Across a population, environmental factors might play a role with regards to any of the factors including distribution by allowing for variations to occur in these traits.
These variations can then be studied and analyzed.
The other options are determined by genetic factors.
A high level of gene flow into a population increases genetic diversity in a population. A high level of gene flow out of a population decreases genetic diversity in a population. Genetic drift is the change in allele frequencies due to "sampling error" factors. Typically, genetic drift has the biggest impact on small populations.
Gene flow (or gene migration) is a mechanism of evolution (change the allele frequencies) which transfers genetic variation among populations due to migration. High level of gene flow decreases the genetic differentiation between the two populations.
Genetic drift is a mechanism of evolution that acts by chance (“sampling error”) often when a population is reduced in size by a natural disaster (bottleneck effect) or when a small group leaves the main population and forms a colony (founder effect).
Answer:
bronze
Explanation:
Bronze, an alloy formed by adding tin to copper, fuses at a lower temperature than copper and is thus better suited for casting; it also is harder and less malleable.
Answer:
From smallest to largest:
Capillaries, alveoli, bronchi. bronchioles, trachea, pharynx, nasal cavity.
Answer:
22 pairs of autosomes, 1 pair of sex chromosomes, I notice that the X and Y chromosomes are sex chromosomes and that they are different in length and size., The sex of this organism is male, as the genotype XY can only mean a male gender; female gender is denoted by the genotype XX., You didn't put in Karyotype A., The special circumstance is with group 21 of chromosomes. There are 3 instead of 2 in that group., This circumstance results in a condition known as trisomy 21, or Down Syndrome. Down syndrome causes a distinct facial appearance, intellectual disability, developmental delays, and may be associated with thyroid or heart disease.
, Name the karyotype "Down Syndrome Karyotype?" (I'm not sure on the last one)
