Answer: A) Black trait is dominant
B) The genotypes of the parents must be Bb
Explanation: Let B represent the allele for black colour and b represent the allele for white colour. If the offspring between 2 black mice show the ratio of 3 black mice to 1 white mouse, it then means that the two parents are heterozygous for black colour, that is each of them have one allele for black colour (B) and one allele for white colour (b). They both have a genotype of Bb.
Bb x Bb = BB, Bb, Bb, and bb.
This means 1BB : 2Bb : 1bb
BB is black, Bb is black while bb is white which gives a ratio of 3 black mice to one white mouse. For Bb to manifest as black, it means that B is dominant to b.
Answer: C: The total mass of glucose and oxygen formed from photosynthesis is equal to the total mass of carbon dioxide and water used up during the reaction.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Photosynthesis is a phenomenon in which green plants containing chlorophyll use sunlight as a source of energy to convert carbon dioxide and water to form glucose and oxygen.
Answer:
air pressure
Explanation:
The diagram shows the concept of air pressure. Air pressure is also called atmospheric pressure. The pressure which is applied by the gases present above in the atmosphere on the object present below on the surface of earth. Atmospheric pressure is measured by an instrument called barometer. One atmosphere is equals to 1,013 millibars, or 760 millimetres of mercury. At sea level, air pressure is maximum while on hilly areas, this air pressure becomes lower due to less gases in the atmosphere.
In applied probability, apopulation process is a Markov chain in which the state of the chain is analogous to the number of individuals in a population (0, 1, 2, etc.), and changes to the state areanalogous to the addition or removal of individuals from the population. 0 votes. 0 votes.
