D) Photosynthesis
Explanation:
Plants use Carbon dioxide in the process that turns sunlight, carbon dioxide and water into glucose and oxygen
6. The man is the father of the child with O blood group since it does not contribute O allele to the child and mother have BO alleles. The child will receive one O from mother since O is recessive allele it will be expressed in homozygous condition which is not possible with this cross.
7 The phenotype is half palamino and half cremello horses are produced . The genotype is HcHcr : HcrHcr (1:1 ratio)
Explanation:
Data given:
blood group of man = AB (genotype is AB)
blood Group of woman = B (genotype can be BB or BO
Child is O type = why
The cross shows
A B
B AB AB
O A0 BO
it is known that each parent contributes one of the alleles to their child in ABO blood system.
The father with AB group is able to pass either A or B allele to the child
Mother with BO could either pass B or O allele to the child. But since 0 is the recessive trait both parents must pass on O allele for the child to be O blood type.
Hence man with AB is not the biological father of the child.
7. data given:
Coat colour in horses depict phenomenon of codominance.
chestnut colour is Hc
cremello colour horse genotype = HcrHcr
plamino colour Hc Hcr
cross shows:
Hcr Hcr
Hc HcHcr HcHcr 2:2 cremello:plamino
Hcr HcrHcr HcrHcr genotype = 1:1 ratio
HcHcr : HcrHcr
If i used the punnett square correctly you have a zero percent chance of getting wrinkled yellow seeds
C, presence of nucleic acid. not all living things are microscopic, many living things have nuclei in their cells, and not all living things need a host cell or body.
