You encounter someone who has never heard of evolution, and they ask you about a population of ducks that live in their grandmothers pond. They tell you that 10 years ago the pong had both large eyed ducks and small eyed ducks. But one day 2 of the large eyed ducks were killed by some wild dogs. Now, the population of ducks has entirely small eyed. Identify the mechanism of change in the duck scenario and use it as evidence to explain evaluation to that person.

Answers

Answer 1

Answer:

The large eyed ducks had an undesirable trait, but the small eyed ducks have a desirable trait. Because the large eyed ducks had a trait that decreases their chances of survival, they wete killed. But small eyed ducks are lucky because they have a trait that increases their chance of survival. The small eyed ducks reproduce more offspring that have small eyes, but the large eyed ducks cannot because they didn't survive. This causes that the allele for large eyes in the gene pool to decrease.

3. Suppose two animals live in the same loca-

adaptation would decrease the competition
between them?

Answers

Answer:

One eats during the day and the other eats at night.

Explanation:

Answer:

Well, it really depends on the type of animal (for example water, land). However an adaptation like being able to eat different foods would decrease competition between them as they don't have to hunt the same prey.

Explanation:

I don't really know how to explain this. Sorry if my answer is bad.

Parent strand of DNA is CCTAGCT. What is the complementary strand?

Answers

Answer:

GGATCGA

Explanation:

Adenine goes with thymine and Cytosine e goes with guanine.

Basically A is with T; C is with G

Note that:

C matches with G

T matches with A

In this case, the strand of DNA given is CCTAGCT. The complementary strand would therefore be GGATCGA.

The mitochondria of eukaryotic cells contain two forms of the EF G protein. EF G1mt acts an elongation factor as expected, but EF G2mt acts as a ribosome recycling factor. Individuals with certain single nucleotide polymorphisms (SNPs) in the EF G2mt gene are known to have an increased number of side effects associated with taking statin drugs that treat high cholesterol. The most common side effect is muscle weakness, but they can be as severe as muscle breakdown and liver failure. Propose a mechanism by which SNPs in the EF G2mt gene may lead to these side effects.

Answers

Answer:

The correct answer is - polymorphism mechanism.

Explanation:

Polymorphism mechanism in mitochondrial elongation factor gene EFG2: It involves escalates the atorvastatin toxicity and affects the cell respiratory function. Polymorphisms within the EFG2 factor gene lead to the implication in disease. This gene factor may result in adverse drug reactions such as STATIN, that can leads to side effect to the condition that can affect skeletal muscle severely.

EFG2 plays an essential role which is specific in mitochondrial ribosome recycling. EFG2mt gene is required for cell growth on galactose medium using small interfering RNA splicing of expression in human cell lines.

Such mutation exhibits an atorvastatin-sensitive phenotype and shows less respiratory capacity. this concludes that the first phenotype associated with SNPs in the EFG2mt gene and implicates the human EFG2mt gene as a pharmacogenetic gene for stain toxicity in humans.

List two general differences between inner and outer planets.

Astronomy.

Answers

Answer:

Inner planets are smaller than the outer planets; gas giants have more gravity; Farther apart, inner planets have a solid surface, Inner planets are hotter, inner planets have a shorter period of revolution. Distance from the sun causes these differences.

Explanation:

The four inner planets have slower orbits, slower spin, no rings, and they are made of rock and metal.

The four outer planets have faster orbits and spins, a composition of gases and liquids, numerous moons, and rings.

The outer planets are made of hydrogen and helium, so they are called gas giants.

Inner planets are closer to the sun while outer planets are farther. Also, inner planets don’t have rings but some outer planets do.
