D: interphase
during this phase , the chromosomes undergoes duplication of chromosome of 1 chromatid into chromosome of 2 chromatids , then the cell is ready for the cellular division.
Answer:
Option (A)
Explanation:
Environmental justice usually refers to a significant portion of the struggle that is extensive carried out in order to improve, upgrade and maintain a clean, hygienic and healthy environment. This struggle is mainly for those people who have traditionally lived, worked and was closely associated with the sources of various types of pollution.
This can also be simply considered as precautionary measures that are taken in order to prevent nuclear destruction, creation, and disposal of hazardous waste materials and other factors that have the potential to affect the resources on earth such as land, wind, water, and food.
Thus, the above given dimensions of environmental problems are issues of environmental justice.
Hence, the correct answer is option (A).
Answer:
If you are AB + you can only donate to AB positive people. However, you can receive blood of any type.
Answer:
Refraction
Explanation: Reflection is when light bounces off a medium at an angle back to its source.
Refraction bends light, so when it's transmitted through a prism, light is refracted into the colors of the spectrum.
So, one at a time: I'm attaching a picture of the punnet squares (hard to make on the computer (and you can simplify the ratios down):
4. HHnn x hhNN
All offspring are HhNn; 100% same genotype (HhNn); 100% phenotype of short, normal
5. HhNn x HhNn
Genotypes and ratio:
HHNN(1): HHNn(2): HhNN(2):HhNn(4):HHnn(1):Hhnn(2): hhNN(1):hhNn(2):hhnn(1)
Phenotypes and ratio:
Short normal (9): short colorpoint(3):Long normal (3): Long colorpoint (1)
6. TtNn x ttnn
Genotypes and ratio:
TtNn(4):Ttnn(4):ttNn(4):ttnn(4) (which is 1:1:1:1)
Phenotypes and ratio:
Tabby normal (1): Tabby colorpoint (1): Stripless normal (1): stripless colorpoint (1)
7. hhNn x hhNn
hhNN(4): hhNn(8):hhnn(4)
short normal (12): short colorpoint (4)
