Weather is an example of rapid environmental changes.
Explanation:
Environment refers to our natural world surroundings. Rapid means fast or quick. Weather around us keeps changing as the earth rotates and revolves around the sun. It changes depending on the month of the year or may change from day to night. You can also note the room temperature at different times in a day, it keeps changing mostly minorly but it does change. There are sunny, foggy, rainy, cold etc days and hence we can say that weather is example of rapid environmental changes.
Answer:
d
Explanation:
Answer:
224 chromosomes
Explanation:
The wing has somatic cells which are formed after successive mitotic division forming diploid cells. On the other hand, the formation of gametes involves meiosis which is a type of reduction cell division that forms haploid daughter cells. Somatic cells have the double number of chromosomes in gamete cells therefore the wing cells have 224 chromosomes.
The answer is; horizontal gene transfer
The other form of gene transfer is the vertical gene transfer where genes are transfers from parents to offspring. Horizontal gene transfer is common in bacteria and is significant in transferring favorable genes such as antibiotic resistance in a bacteria population. An example of this horizontal gene transfer in bacteria is conjugation and transformation.
Parent's genotypes are Bb and Bb andn the offsprings genotypes after crossing them will be BB, Bb and bb while phenotypes of 3 white rabbits and 1 brown.
The genotypes of a specific cross or breeding experiment are predicted using the Punnett square, a square diagram. It bears Reginald C. Punnett's name, who developed the method in 1905. Biologists use the figure to calculate the likelihood that a child will have a specific genotype.
A person's genotype is made up of all the alleles they have for a certain gene. The sum of a person's attributes or observable characteristics is their phenotype. Unlike phenotype, which is only impacted by genotype, genotype is directly inherited from a person's parents.
Assume B is white, b is recessive brown ; Bb x Bb
B b
B BB Bb
b Bb bb
Genotypes: BB, Bb, bb
Phenotypes: 3 white, 1 brown
