Answer: Mitochondria are present in the cells of all types of aerobic organisms like plants and animals, whereas Chloroplast is present in green plants and some algae, protists like Euglena.
Explanation:
The hormone to be given is oxytocin. Oxytocin is a hormone produced by the paraventricular nuclei of the hypothalamus then stored in the posterior pituitary gland (along with antidiuretic hormone or vasopressin) that is responsible mainly for uterine contraction and milk ejection or letdown. Oxytocin induces contraction of the myoepithelial cells in the breast for milk letdown. On the other hand, there is upregulation of oxytocin receptors during parturition which makes the uterus more sensitive to oxytocin. Oxytocin is also known to induce labor and reduce post-partum bleeding.

Answer:
1/8 (12.5%)
Explanation:
An autosomal recessive disease is an inherited disease in which an individual need to receive both defective alleles at the same gene <em>locus</em> to be expressed in the phenotype. In this case, both parents are carriers of the recessive mutant allele associated with the sickle cell anaemia trait, thereby both parents are heterozygous, ie., each parent has one copy of the normal allele 'H' and one copy of the defective mutant allele 'h' associated with this condition. In consequence, their first child has a 1/4 (25%) chance of having sickle-cell anaemia. Moreover, the chance of having a girl is 1/2 and the chance of having a boy is 1/2, thereby the final chance of having a girl sickle cell anaemia individual is 1/4 x 1/2 = 1/8 (12.5%).
- Parental cross for sickle cell anaemia trait = Hh x Hh >>
- F1 = 1/4 HH (normal); 1/2 Hh (normal); 1/4 hh (sickle cell anaemia) >>
- Sex proportion of sickle cell anaemia individuals = 1/8 female sickle cell anaemia individuals + 1/8 male sickle cell anaemia individuals (1/8 + 1/8 = 1/4)
