Answer & explanation:
Melanism occurs due to a genetic mutation that causes the excessive and concentrated production of the black pigment, called <u>melanin</u>. The consequence is living beings with darkened skin or fur. There are three types of melanism.
Adaptive melanism occurs by the need to adapt to the environment, a condition that will be passed through the generations. This melanism allows animals to camouflage themselves during hunting or to hide from predators.
Industrial melanism is related to human interference, especially industrial activities, in the lives of animals (dark-colored moths are the best-known cases). Air contamination is one of the main factors for this condition.
There is also pseudo-melanism, which partially affects animals and is generally motivated by genetic mutations. In certain species, the characteristic spots and stripes appear larger and darker than usual. This type of melanism is very present in cats such as tigers, cheetahs, leopards. However, other animals can still be affected.
As the temperature increases so does the pressure of the air inside the tire. If the pressure becomes higher than the tire can hold the tire will burst.
The correct answer is option B, that is, all living organisms are composed of one or more cells, which came from pre-existing cells.
A scientific theory refers to a well-substantiated illustration of some characteristic of the natural world, on the basis of a number of facts, which have been repeatedly confirmed via the experiment and observation. Such fact-supported theories are not hypotheses, however, are reliable explanations of the real world.
During the late 1830s, the zoologist Schwann and the botanist Schleiden were examining tissues and postulated the unified cell theory. According to the unified cell theory, all the living things comprises of one or more cells, the cell is the fundamental unit of life, and the new cells originate from the pre-existing cells.
The birth and reproduction of Carrier(Heterozygous) organisms, (i.e) heterozygous individuals that have a dominant allele masking the effects of the recessive 'lethal gene.' However even though the gene is masked, it is still there. Therefore, if the heterozygous individual is to reproduce with another heterozygous (carrier) organism there is a higher chance that their offspring will have the active form of the 'lethal gene' causing the death of the offspring.
Explanation:
We have attached a figure that shows the diagram of the given equation.
We need to find how many angles are alternate exterior angles with angle 5?
We know that an exterior angle is the angle that is made outside of the shape and an alternate angle is the angle opposite of a transversal line of another angle.
From the figure, 8, 7, 9, 10, 12, and 11 are the angles that are on the same transversal. 8, 7, 9, 10, and 12 are just exterior. It means that 11 is the alternate exterior of angle 5. So, only one angle is alternate exterior angles with angle 5.
