Answer:
Magma
Explanation:
This rock is made of cooled magma
CORRECT ANSWERS: “Eye color is controlled by many genes” and “Eye color has a polygenic inheritance pattern”
***These two answer choices are actually saying the same thing. (poly = many, so polygenic just means a trait is controlled by many genes) These are the best answers because traits that are controlled by several genes have many different phenotypes (traits) that can result (ex: blue eyes, green eyes, brown eyes, hazel eyes...etc).
WRONG ANSWERS: “Eye color is controlled by only one pair of genes”
***The trait is most likely controlled by more than one pair of genes because there are three different phenotypes discussed in the problem. There are inheritance patterns where one gene can cause three phenotypes (complete dominance and incomplete dominance), but these produce a combination of the traits (brown AND blue eyes...doesn’t make much sense) or a mix of the traits (whatever color brown mixed with blue gives you...still probably not green). Anyways, it’s a feasible answer but definitely not the BEST.
“Eye color is not an inherited trait”
***All traits are determined by the genetic code we inherit from our parents. The way our cellular mechanisms express of those traits can vary and be determined by environmental factors, but this is still by far the least accurate statement.
“Eye color is inherited from only one parent”
***For any given gene we receive one allele (copy of that gene) from each parent. Therefore, all of our traits are inherited from both parents. Again, the expression of those traits varied based on patterns of inheritance, environmental factors...etc, but this is another very poor answer choice.
Answer:
increases
Explanation:
Habitat is defined as a particular environment where a group of organisms normally lives. Some examples of habitat include, among others, forests, deserts, lakes, grasslands, etc. Moreover, an edge habitat refers to a habitat area that is in contact with another. This part of the habitat has ecological importance because it is used by many species in order to find food, refuge and rest. In the question above, it is expected that a greater number of smaller habitats increase edge habitat surface area when compared to the interior habitat area. The ratio between the edge habitat surface area and total habitat area may have a huge impact on entire ecosystems.
Answer:
El Niño impacts weather systems around the globe, triggering predictable disruptions in temperature, rainfall and winds. La Niña is the opposite – a cooling phase of ENSO that tends to have global climate impacts opposite to those of it. El Niño refers to the above-average sea-surface temperatures that periodically develop across the east-central equatorial Pacific. It represents the warm phase of the ENSO cycle. La Niña refers to the periodic cooling of sea-surface temperatures across the east-central equatorial Pacific.

Answer:
The correct answer is Single Circular DNA Molecule.
Explanation:
A bacterial genome, which is the DNA that is found in bacteria collectively, is a double stranded circular DNA. So it has no start and end like double stranded helix DNA. The option D, which is "Single Circular DNA Molecule" is correct.
