Answer:
Slump, weathering and creep.
Explanation:
Freeze and thaw cycle is a geological process which occur in the cold season. This occur when a crack in the rock accumulate and is fill with water, it then freezes as the temperature reduced thereby causing expansion in the rock and making it bigger. This then melt in the warm season exerting a force that which is due to expansion and contraction.
The three processes of freeze and thaw cycles are slump, weathering.and creep.
Slump is a geological process that occur when loose coherent layers of rock transport down through a short distance down a slope. It is characterized by by sliding along a concave-upward or planar surface.
It is caused by freezing and thawing, earthquakes shock e.t.c.
Weathering which breakdown rocks into small pieces to form soil which is caused by temperature.
Freeze and thaw help in weathering because it cause the crack rock accumulated with water to break.
Creep refer to process where debris or soil move through down slope. It's effect is seen in bent trees, tilted fences e.t.c.
Sound intensity, also known as acoustic intensity, is defined as the power carried by sound waves per unit area in a direction perpendicular to that area. ... One application is the noise measurement of sound intensity in the air at a listener's location as a sound energy quantity.
Answer:
Sensory Evaluation
Sensory evaluation defined as the ‘systematic study of human response to physico-chemical properties’ makes it possible to obtain information about the sensitivity of the human sense and about the four dimensions of the sensory perception, i.e. the quantitative, the qualitative, the temporal and the hedonic dimensions.
Answer:
D) epigenetic phenomena.
Explanation:
All that a living being is, anatomically and functionally, even in its behavior, is determined by the genes that in a very complex interaction with the environment build living beings. Genes articulate the responses of cells (and therefore of the organisms that carry them) to environmental stimuli, interaction with other genes (of other cells and other living things) and fundamentally direct the self-construction of any living being.
The genes regulate themselves, establishing a very sophisticated kind of program, with very precise spatial and temporal dimensions. How this regulation is achieved, what principles guide it is the subject of the study of molecular biology. But genes are also transferred from one generation to another. The cells divide and inherit their genes to the offspring. Other cells - gametes - carry the information to be inherited from parents to children or from generation to generation. What rules genes follow in this path of inheritance of individuals, species, populations, is the subject of study of genetics.
Genes are constructed of DNA (acronym that names deoxyribonucleic acid). The total gene content of an individual is called a genotype and the effect that the genotype activity causes on the individual (appearance, structure, functioning) we call it a phenotype. The mechanisms of functioning and regulation of genes involve chemical activity on DNA, including changes in its sequence (mutations). Epigenetic phenomena are defined as any change in gene expression (change in phenotype) that is inheritable but does not involve DNA mutations (genotype modifications). Epigenetics refers to any process of regulation of genes that do not imply changes in the DNA sequence. If the DNA contains information (genes), epigenetics deals with the genetic information that is outside the genes.
Answer:
The correct answer is - Noctural worms have the advantage over diurnal due to the fact that the nocturnal worms are burrowing during the feeding time of birds.
Explanation:
Natural selection is the process in which organisms adapt according to environmental changes to increase their survival rate. Natural selection leads to natural changes in different organisms.
In this case, diurnal worms are forced by the natural selection here to adapt to the change if they want to survive. Here, natural selection works for the nocturnal and against the diurnal.
