Answer:
1) In the first step, we need to predict the possible alleles for the cross. The dominant allele will be written with a capital letter. The recessive allele will be written with a small letter. Hence, the allele for brown hair colour will be B and the allele for red hair colour will be b.
2) In the second step, we need to determine the genotype of the parents. The genotype of the homozygous dominant parent will be BB. The genotype of the heterozygous brown hair colour will be Bb.
3) The punnet square for cross between these parents can be shown as follows:
B b
B BB Bb
B BB Bb
4) In the fourth step, lets determine the phenotype of the children. The phenotype of all the offsprings born will be brown hair colour.
5) The genotype from the punnet square shows that there is a 50% chance that the offsprings will be heterozygous dominant (Bb) for brown hair colour and their will be a 50% chance that the child born will be homozygous dominant (BB).
Answer:
Rafflesia arnoldii is a tropical plant with a huge blood-red flower, which emits heat and emits the smell of decomposed meat. What use are these adaptations to this plant
Explanation:
The smell is adaptation for pollination.This is because it attracts insects which carry on the process of pollination.
Its possible Endothermy characteristic is for mimicry Its releases heat to attract the pollinators- blowflies.The endothermic mechanism is well pronounced during flora development: which further buttress the fact that this is related to pollination to attract blowflies, and not to thermoregulation.
They both have an egg cell wall, a vacuole, and chloroplast, smooth and rough ER, and much more.
Onion skin is treated to be a tissue because it is thin and - brittle.
The skin cells of the onion get a well which gives- the outer portion its rigid shape.
Answer:
C) Primary, tertiary and quaternary levels of protein structure
Explanation:
Primary structure; Covalent bond is present in form of peptide bond in the primary structuture of proteins. The amino acids are held together in the polypeptide chain by peptide bond.
Tertiary structure; Disulfide bonds are present between cysteine amino acids, that keeps the parts of polypeptide chain strongly attached to one another.
Quaternary structure; The Quaternary structure of protein is held together by hydrophobic interaction and disulfide bonds.
Answer:
Lactic acid fermentation occurs in the cytoplasm of the cell.
It's a form of anaerobic respiration, and occurs when oxygen is unavailable in animal (muscle) cells and in some bacteria.
