Answer:
Natural Selection
Explanation:
A random genetic mutation gave rise to the dark colored moths. All types of living things have small differences between the individuals in the species. If one of those differences allows the individual to live longer, they will likely have more offspring. As that trait is passed on, the population starts to look more like a successful individual. Over time, the species changes.

how is a pot of water is an example of radiation?
Answer:
For example, when a pot of water is placed on the stove to boil, conduction heat warms up the pot, which then heats the water molecules inside. As these molecules heat, convection causes them to move away from the interior of the pot as they are replaced by cooler molecules.
What conditions are necessary for rocks to melt?
Answer:
In explanation.
Explanation:
The rock is pulled down by movements in the earth's crust and gets hotter and hotter as it goes deeper. It takes temperatures between 600 and 1,300 degrees Celsius (1,100 and 2,400 degrees Fahrenheit) to melt a rock, turning it into a substance called magma (molten rock).
The rock can be melted when high pressure and high temperature are applied to it, and due to the compression relaxation, the rock melts. The different types of rocks need different temperatures.
What is the effect of temperature on different substances?Temperature plays an important roles in different substances, such as high and low temperatures, each with its own set of tasks. The high temperature can melt the solid substance into a liquid, and further heating converts the liquid into gas. Because of the high pressure and temperature in the earth's core, the rock is in a molten state, but when it comes out of the earth's core, after solidifying, it converts into solid rock. The low temperature converts the liquid into a solid, and food preservation is carried out by this process.
Hence, the rock can be melted when high pressure and high temperature are applied to it, and due to the compression relaxation, the rock melts.

Perennial plants in the genus Asclepias (milkweeds) contain compounds called cardiac glucosides (cardenolides) that can be toxic for animals. Monarch butterfly larvae feed on Asciepias sp. but are not harmed by the cardenolides. Instead these molecules accumulate in the tissues of the caterpillar and are present in the tissues of the adult butterfly. Because of these toxins in their tissues, Monarch butterflies are unpalatable to insectivorous birds. Another species of butterfly, the Viceroy, looks very similar to the Monarch in its bright coloration and distinctive patterning but was thought to lack a toxin. Because Monarch butterflies are toxic it was long thought that the similar appearance of nontoxic Viceroy butterflies was an example of:
Answer:
Batesian mimicry
Explanation:
Batesian mimicry refers to a form of biological resemblance by which a harmless prey species evolved in order to imitate another harmful species for a common predator, thereby increasing its chances of survival. This defensive behavior was described by Henry W. Bates, who made ecological observations of butterflies in the Brazilian rainforest. Thus, an innocuous species that show harmful signals against a predator will gain protection against this predator. Batesian mimicry is a type of mimicry that benefits from the predator's learned avoidance behavior.

There are now several effective antimalarial drugs that can treat people who have malaria or prevent them from getting the disease altogether. Predict what will happen to the frequency of the sickle cell allele over the next 100 years as these drugs become more widely used by people living in areas where malaria is endemic: _____________ Predict what will happen to the frequency of the sickle cell allele over the next 100 years in areas like Boston MA, where there is no incidence of malaria: __________ stay the same ; stay the same decrease ; increase increase ; increase increase ; decrease decrease ; decrease
Answer:
decrease, decrease
Explanation:
By using antimalarial drugs in order to prevent malaria, the frequency of the sickle cell allele decreases in both areas where malaria is endemic and the areas where no incidence of malaria occurs because there is no necessity of sickle cell allele in the population to prevent malarial disease. Sickle cells have high significance in prevention of malarial diseases so when there is no malaria happens in the population so there is no need for it and the allele slowly removed from the population and decrease occurs in its frequency.
The physical expression of an organism's genes is its:
Answer: phenotype
Explanation:
Blue flower is dominant to yellow flower. Tall plant is dominant to short. Cross BbTt * BbTt. What precenetage of the offsprings are expected to be heterozygous for both traits?
Answer:
The correct answer would be - 25%.
Explanation:
It is given that the Blue flower is dominant over the yellow flower which means Blue is represented by allele B here and allele b for yellow and Bb is a heterozygous case with a blue phenotypic character. Similarly, the Tall plant is dominant over short and represented by T and t respectively.
BbTt is a heterozygous condition and a cross with itself will produce :
Gametes: BT Bt bT and bt
BT Bt bT bt
BT BBTT BBTt BbTT BbTt
Bt BBTt BBtt BbTt Bbtt
bT BbTT BbTt bbTT bbTt
bt BbTt Bbtt bbTt bbtt
Here 4 out of 16 offspring are heterozygous for both traits represented by bold alphabets. Therefore the correct answer is 25%
The stars appear to move across the sky every day, but
their paths change throughout the year. Here is a model of
the Sun-Earth system.
Based on the model, which three factors might cause this change in the
apparent movements of the stars?
Answer:
Earth's Revolution around the sun, The tilt of Earth's Axis, and Earth's rotation on its axis.
Explanation:
I have done this test
1. The Earth's revolution around the Sun: As the Earth revolves around the Sun, the stars appear to move across the sky each day. This is because the Earth is rotating on its axis, which causes the stars to appear to be moving from east to west.
2. The Earth's tilt: The tilt of the Earth's axis also has an effect on the apparent movement of the stars. As the Earth rotates around the Sun, the tilt of the Earth's axis changes throughout the year. This causes the stars to appear to move slightly differently at different times of the year.
3. The Precession of the Equinoxes: The precession of the equinoxes is the gradual wobble of the Earth's axis which takes place over thousands of years. This has an effect on the apparent movement of the stars, as the angle of the Earth's axis changes over time. This causes the stars to appear to move in a slightly different pattern than they did thousands of years ago.
