Answer:
Photosynthesis can be described as a process in which carbon dioxide and water get converted into glucose and oxygen in the presence of light energy. Oxygen is produced as a by- product for this reaction.
The presence of chlorophyll is vital for the process of photosynthesis to occur. The light energy from the Sun is trapped by the chlorophyll present in the chloroplast. Hence, if chlorophyll will not be present then light energy would not be trapped by the plant and photosynthesis won't occur.
Answer:
a dominant mutation
Explanation:
A monohybrid testcross is a cross-breeding experiment used to determine if an individual exhibiting a dominant phenotype is homo-zygous dominant or heterozygous for a particular phenotypic trait (in this case, wing length). In a monohybrid testcross, a 1:1 phenotypic ratio shows that the dominant parental phenotype was a heterozygote for a single gene that has complete dominance. Moreover, a 3:1 ratio in the F2 is expected of a cross between heterozygous F1 individuals, which means that 75% of individuals with short wings have the dominant allele that masks the expression of the long-wing trait (i.e. the recessive allele).
Answer:
Age structure diagrams show the following.
The height of the graph indicates life expectancy.
The width of the base shows birth and fertility rate.
The slope of the pyramid-shaped diagram indicates death rate.
Bends in the graph indicate reductions in birth rate or increases in
death rate.
The overall shape of the diagram indicates whether it is an economically developed country or not.
Explanation:
In a stable human population, the age structure diagram looks like a pyramid with a narrower base. The narrower base depicts that the birth rate is low. A stable human population also has a high number of older individuals. A greater number of older people in a population shows that quality of life is high in that area/country and the population has access to nutritional diet, medical care, and healthcare services. These features of the age pyramid in a stable population indicate a developed country. Age pyramids of underdeveloped countries have a wider base (high birth rate) and narrow tip.
