I don’t think we would have the same countries. i feel like everything would be connected, like maybe a few really big countries instead of hundreds of different countries. i feel we would look different that how we already look because there would be more of different type of people around each other, resulting in mixed race reproducing.
The enzyme pectinase speeds up the breakdown of pectin in fruits, producing more juice. It speeds up breakdown of pectin in plant cell walls, thus creating more juice. It is also used in wine making to avoid cloudiness
Answer:
Mendel's law of segregation states that every living organisms comprises of two alleles for each trait. During the process of meiosis of cell division each allele segregate to form two gametes each containing a single allele.
Explanation:
Mendel conduct experiment of different traits of pea plants. He considered the first generation as F1 and second generation as F2. Each and every of all the traits of pea plants show same pattern of inheritance. In the F1 generation one of the two traits under consideration disappears, this forms the recessive traits. While in the next generation, that is , F2 generation the recessive trait again reappeared. The ratio of dominant and recessive traits being 3 and 1 respectively.
In human being, sex chromosomes determine the gender of the offspring. Hence Paternal chromosome would be XY and maternal would be XX. According to punnett square method, the genotypes of offspring would be:
Hence 2 male (XY) and 2 female (XX) offspring conclude that there is 50-50 chances of a couple producing male or female offspring.
A hypothesis that is not supported be the data is rejected
Answer:
staphylococci
Explanation:
Gram stain -
it is the method of staining which classify the species of the bacteria into gram - positive and gram - negative .
This method distinguish the bacteria by its physical and chemical properties of the cell well of the bacteria .
1. In case of gram - positive , the stain is of color violet , because to its thick cell wall .
and ,
2. In case of gram - negative , the stain is of pink color , because to thinner cell wall .
The bacterium , which shows Gram - positive coccus after the gram stain is staphylococci .
