The nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. Nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and DNA, the building blocks of all life .
Answer: The phenotypic variation was more in play during the tests because of the presence of environmental factor (monochromatic light). The genotypic variation was a result which is evident in the viable and fertile hybrids
Explanation: Phenotypes are traits of living things which are visible to us. Examples of such traits are behaviours, colour, shape, size, e.t.c. Genotypes is the genetic blueprint of a living thing. It is the genetic code that forms the physical traits in an organism (phenotype). For example, the code that tells a lady to have red hair is the genotype while the resulting red hair in the lady is the phenotype.
Phenotypic variations simply put are different physical variables in phenotypes that exists in a given population. For example, we have people with different body weights, heights, eyecolour, hair and shape of head. Genotypic variation is the difference in genotypes between different species or individuals of the same species.
There are two known causes of phenotypic variations and they are genes or environmental factor. In the given data, the monochromatic (made of one colour) light induced phenotypic variations in the male species and led to indiscriminate mating which resulted in viable and fertile hybrids (genotypic variation).
Answer: An object with a high mass close to the Earth could be sent out into a collision course with the asteroid, knocking it off course. When the asteroid is still far from the Earth, a means of deflecting the asteroid is to directly alter its momentum by colliding a spacecraft with the asteroid.
Explanation:
Hope I could help :))
Answer:
Option (A).
Explanation:
Sociology may be defined as the subject that focus on the study of development and social interaction in society. Sociology is also known as the general science of the society.
