Answer:
Water carries several physical properties such as chemical formula, appearance, boiling point, freezing point, density, viscosity and solvency.
An increase in temperature changes the density of water. When a water is heated or its temperature is allowed to increase it causes the water molecules to gain energy and move faster, which results in increase in water volume due to movement of water molecule far from each other. on the other side if temperature of water is decrease, it's molecules come closer to each other and decrease in the volume of water takes place.
Answer:
A. Lightning
Explanation:
Nitrogen is very fundamental for a wide range of life activities in both plant and animals.
Lightning which accompanies thunder during rain storm and other weather phenomenon aids the release of atmospheric nitrogen for life processes. The energy that accompanies a lightning event is mostly electrical in nature. This electrical energy is huge and very massive. As the lightning interacts with free nitrogen molecules in the atmosphere, the molecule is broken down. The free nitrogen which results then combines with oxygen in the atmossphere to form oxides of nitrogen. When oxides of non-metals dissolves in rain water, they make the water rich in nitric acid and can be brought to the biosphere for use by plant and animals.
The twenty- first pair of chromosomes failed to seperate during meiosis, so aziz received three of these chromosomes rather than the normal two. Aziz has down syndrome.
The physical expression of genes are phenotype. Phenotype is the expression of the gene by the appearnace of the organism. It is the characteristics of that trait.
Examples : When pigment is made in our eyes, height ( tall and short) , weight, blond hair is the phenotype for the blond hair genotype and skin colour( black, white ) is the phenotype trait.
Answer:
physical, cognitive, socio-emotional
Explanation:
The complete question is as follows:
According to the text, the interaction of what three developmental domains shapes human development?
Select one:
a. social, physical, moral
b. mental, physical, environmental
c. physical, cognitive, socio-emotional
d. environmental, genetic, perceptual
- The term domain describes the specific aspects of the change and growth that takes place in relation to the human development.
- The three main developmental domains that shapes human development are :physical, cognitive and socio-emotional domains.
- The physical domain includes the physical changes and growth that takes place in a human body. It also includes the development of the motor skills and the use of senses.
- The cognitive domain covers the aspect of development creativity and intellectual skills. It includes various factors such as memory, attention, planning, thought processing and accomplishing goals.
- Socio-emotional domain includes the ability to deal with emotions and udnerstanding others emotions. This is a phase of developing attachments and interaction skills. During this phase the cooperative nature, empathatic nature and morality of an individual develops.
