The correct answer is A and C.
China's geographic location, with Gobi in the North, and to the West is Himalaya and seas to the east and south, which isolated early chinese civilization from other cultures.
C. China's civilization which is the oldest continuous civilization which i found in the world.
China civilization is the oldest written record in history. In the writings of shang they don't indicate any existence of the Xia.
Answer:
Describe a typical prokaryotic cell. a. It has a cell wall enclosing cell membrane, cytoplasm, ribosomes and nucleoid region with genetic material. It may have a protective capsule, flagellum, pili and plasmids. b. It has a cell wall enclosing cell membrane, cytoplasm, ribosomes and nucleus containing genetic material. It may have a protective capsule, flagellum, pili and plasmids. c. It has a cell wall enclosing nuclear membrane, cytoplasm, ribosomes and nucleoid region with genetic material. It may have a protective capsule, flagellum, pili and plasmids. d. It has a cell wall enclosing nuclear membrane, cytoplasm, mitochondria, vacuoles and nucleoid region with genetic material. It may have a protective capsule, flagellum, pili and plasmids.
Explanation:
Answer:
The "reproductive handicap" in sexual reproduction can refers to that only half of the offspring will be female.
It means that a female undergoing asexual reproduction will have offspring with 100% of her DNA, while a female with sexual reproduction usually only transfers 50% of her genetic material to her offspring.
Explanation:
In the given question, the trihybrid cross has been provided for the height trait and it is provided that recessive alleles (aabbcc) contribute 10 cm whereas dominant allele (AABBCC) contribute 22cm.
The height contributed by each dominant allele (A+A+B+B+C+C)= 22cm
The height contributed by each recessive allele (a+a+b+b+c+c)= 10 cm
The dominant genotype is 12 cm taller than recessive genotype which indicates that dominant allele contributes 2 cm.
In trihybrid cross-64 genotype will be formed with these dominant allele based on which the height of the plant will be determined.
The genotype with dominant allele (Height) and F2 progeny are
0 (10cm) - 1/64
1 (12cm)- 6/64
2 (14cm)- 15/64
3 (16 cm)- 20/64
4 (18cm)- 15/64
5 (20 cm)- 6/64
6 (22 cm)- 1/64
