A father is heterozygous (AO) for his type A blood and a mother is heterozygous for her type B(BO) blood. What percentage of their offspring would you expect to have a child with O type blood?
Answer:
2 : 2 BO : OO
Explanation:
Children either have blood group B or O thus the probability of a child being either blood group B or O is 50%.
How have freshwater and salt water fish adapted to deal with osmosis in their respective environments?
Answer:
Salt water fish are perfectly adapted to their salty environment and need osmosis to live. The replacement fluid taken on to replace the lost water is desalinated by a process known as diffusion. Diffusion allows fish to live in a state of constant osmosis

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.

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.

Explanation:
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.
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%
