Suggest why energy from the sun flows in one direction while materials are cycle within an ecosystem
Answer:
Energy flow in an ecosystem is unidirectional. It means that energy which is absorbed by the producers from sun and is converted into chemical energy, always flow from a lower trophic level to a higher trophic level as in a food chain when herbivore consumes producers the energy is transferred from producers to consumers and so on. Some of this energy is assimilated some is used by the organism and some is dessipated in the environment but the flow of energy is never reverted, that is obviously a producer can not consume a consumer.

If you took DNA samples from two strangers on a street, how similar would
their DNA be?
A. 100% the same
B. 95.5% the same
C. 99.9% the same
D. 90.0% the same
If one took DNA samples from two strangers on a street, the two DNA samples will be 99.9% the same (option C).
What is DNA?DNA is the part of a living organism that carries or stores genetic information.
The DNA molecule is made up of four nucleotide bases namely;
AdenineGuanineCytosineThymineHowever, the DNA of every living organism is the same with the difference lying in the arrangement of the nucleotide sequence.
Therefore, if one took DNA samples from two strangers on a street, the two DNA samples will be 99.9% the same.
The 0.1% difference is attributed to the mutations that might have occured in the genome.

2. Medium ground finches with relatively large beaks tend to have offspring with relatively large beaks
3.Birds with a beak type poorly shaped for the current environment are able to adapt by changing their beak types
4. Speciation, or the evolution of new species, in Galapagos finches results because natural selection favors different beak types on different islands.
False When species come into contact with closely related species, they interbreed and become one species again.
What process lead to the speciation of the Galapagos finches on the different islands?
All of them grew from one progenitor species, which inhabitated the islands only a few million years ago.
This process, whereby species develop rapidly to use empty ecospace, is called as adaptive radiation.
Thus, its false, When species come into contact with closely related species, they interbreed and become one species again since its an example of evolution.

Protein are the vital part of any organisms as it helps in growth and repair. The statement that best describes the molecular structure of a protein is option B, i.e., It is a complex, folded chain that helps regulate cell processes.
What is the need of protein folding?Protein has four main structures, namely primary, secondary, tertiary and quaternary structure. It is a complex, folded chain that helps regulate cell processes.
Each structure differ from each other in the way of folding.
The folding of protein makes the protein active to determine its main functions.

Some cities hang their traffic
lights from left to right, rather
than from top to bottom.
Explain why this might cause a
problem for a driver with red-green perception deficiency.
Answer:
The angle and location
Explanation:
There are some who can't perceive the order of red and green together. Having it angled up and down is safer because you know out of common sense that red is on top and green is on the bottom. Having it sideways makes the light elevated on the same level, deceiving the eye better.
Some cities hang their traffic lights from left to right rather than from top to bottom, and this causes problems for drivers, as the left-to-right orientation of traffic lights can pose a problem for drivers with red-green perception deficiencies.
What role do traffic lights play?Traffic lights typically have three colors, such as red, yellow, and green, which are arranged in a vertical orientation in most cities, but in some cities, traffic lights are hung in a horizontal or left-to-right orientation, which can be challenging for those who have red-green color blindness. The traffic lights are there to prevent accidents.
Hence, some cities hang their traffic lights from left to right rather than from top to bottom, and this causes problems for drivers, as the left-to-right orientation of traffic lights can pose a problem for drivers with red-green perception deficiencies.

Summer solstice occurs when the Earth's North Pole is tilted away from the sun shortest day. Winter solstice occurs when the Earth's North Pole is tilted away from the sun. shortest day. Winter solstice occurs when the Earth's North Pole is tilted toward the sun. longest day.
Answer:
In North America, around June 21, Earth tilts on its axis toward the sun, which is Summer Solstice and when the Northern Hemisphere has the most daylight of any time of year. Winter solstice the Northern Hemisphere tilts the farthest away from the sun and when we have the least amount of daylight of any time of the year.
Explanation:
As Earth revolves around the Sun, it rotates on its axis. Sometimes Earth tilts toward the Sun which is when Summer occurs. In the Winter Earth tilts away from the Sun.
In the northern hemisphere summer solstice occurs when the earth north pole is tilted towards the sun, longest day and winter solstice when the earth north pole is tilted away from the sun shortest day . Thus both the option a and c are correct.
What are solstices?Solstices occurs when earth is pointed directly towards the sun. This incident happens twice a year during earth's orbit.
On June 21 the north pole is tilted 23.5 degree towards sun and the northern hemisphere experience summer solstices which is known as longest day of the northern hemisphere year.
On 21 June, the southern hemisphere is tilted 23.5 degree away from sun and southern regions of earth experience the shortest day of the year which is known as winter solstices.
Therefore In the northern hemisphere summer solstice occurs when the earth north pole is tilted towards the sun, longest day and winter solstice when the earth north pole is tilted away from the sun shortest day . Thus both the option a and c are correct.
