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?

Answers

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?

Answers

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.

C. To confirm that the alternative fuel is cleaner than fuels currently used

Explanation:

The current fuels from mining, cutting down trees and even transportation is bad for the atmosphere. These fuels cause climate change which could potentially bring a lot of dangers. The reason scientists would conduct research on a newly alternative fuel is so that the fuel would be a lot more cleaner which could prevent the dangers that are to come.

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:

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.

What conditions are necessary for rocks to melt?

Answers

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 following passage explains the relationship between tectonic plates and earthquakes. Which sentence states incorrect information?


Tectonic plates can push together, pull apart, or slide past each other at their boundaries. The edges of tectonic plates are not smooth, so they create friction as they move. When friction is too great for the plates to move, they can become stuck and pressure can build up. An earthquake occurs when pressure that has built up between plates suddenly is released. The buildup of pressure that leads to earthquakes only occurs at plate boundaries.​

earthquakes occur when the edges suddenly become unstuck and slip along a fault
