The rigth answer is C (B ==> A ==> C)
The 3 images represent the key stages of mitosis.
Image B represents the beginning of the anaphase, where the chromosomes are aligned in the equatorial plate.
The image A represents the anaphase where the chromosomes are separated on both sides of the cell.
The image C represents the telophase or one can observe in the middle the formation of the division furrow to allow the cell to cut itself in two.
Answer:
The conditions for natural selection are:
- overproduction of offspring
- variation among organisms in a population
- favorable adaptations selected by nature
Explanation:
- Natural selection is the continuous process of reproduction and survival that is caused by the contrast and differences due to phenotype.
- Overproduction of species creates the competition and only the one survived through the natural selection grows to the next generation.
- Similarly variations in the phenotypic organization of species, their adaptation process etc causes the natural selection.
- Natural selection is the gateway for the evolution.
Answer:
Frequency of BBBB genotype = 0.68
Frequency of BBBG genotype = 0.2
Frequency of BGBG genotype = 0.12
Explanation:
Genotype frequency = number of individuals of that genotype/ total number of individuals
In this population three types of individuals are present: blue, turquoise and green.
Frequency of BBBB genotype (blue) = 170/ ( 170 + 50 + 30)
= 170/250
= 0.68
Frequency of BBBG genotype (turquoise) = 50/250
= 0.2
Frequency of BGBG genotype (green) = 30/250
= 0.12
The correct answer is C. sewage discharge.
Even though there might even be no harmful pathogens at all if there isn't any waste, it is correct because it is implied that there is waste such as fecal matter inside of the sewage discharge.
neutralisation is the process of converting an acid or a base into the pH value 7.The 2 things produced r hydrogen gas and a salt.
acid+base=salt+hydrogen gas.This often occured in your stomach. when you have gastroble you are eating tablets which are base and a reation take place with hydrocloric acid in it
hope it helps
