Oxytocin is commonly used in modern obstetric practice to increase uterine activity, in cases in which the labor process has failed, with the aim to enable it to progress to a vaginal delivery 3 .
According to the cladogram, Osteichthyes belong in group A.
Osteichthyes are a class of fish that have real bones and jaws as derived traits. These derived qualities can therefore be traced backwards from group A, with each line indicating a connection or relationship.
What is Cladogram?
- In cladistics, a cladogram is a diagram that is used to depict relationships between species.
- Cladograms reconstruct the taxa's evolutionary history (phylogeny) by showing these links. Phylogenies and trees are other names for cladograms.
- A cladogram's root, clades, and nodes are its most important components. The root is the first ancestor shared by all groups that branched off from it. The branches that represent related groups and their shared ancestors are known as clades. The points known as nodes represent the fictitious ancestors.

Answer:
deletion mutation
Explanation:
these mutation are dangerous cause of how each amino acid read in threes so if a base is deleted the whole frame is shifted
Answer: The chances that the baby will have type O is 25%
Explanation: Both the male and female are heterozygous for type B blood, this means that they both have one dominant allele for type B blood and one recessive allele for type O blood. Remember that in the ABO blood system, The alleles for type A and B are dominant while the allele for type O blood is recessive.
This means that the genotypes of both parents for type B blood is BO.
BO x BO = BB, BO, BO, and OO.
Phenotypically, BB and BO will manifest as type B blood while OO will manifest as type O blood.
From the cross between the two parents, one out of the four offsprings has type O blood, therefore the chances of a child having type O blood is 1/4 x 100 = 25%.

Answer:
1. Cork Cambium
2. Vascular Cambium.
3. Xylem cells ; Phloem cells
4. Xylem cells
5. Xylem cells
Explanation:
In plants, growth is characterized by the elongation of the stem and roots. Woody plants also gradually increase is girth throughout their life times. Plant growth is divided into two types depending upon the two growth dimensions (height and width):
Primary Growth:
The elongation or increase in the lengths of the stem and roots is termed as primary growth. Primary growth occurs due to the rapid cell division at the shoot and root apical meristems. This rapid growth of the apical buds is called apical dominance and it prevents the development of lateral buds.
Secondary Growth:
Secondary growth is the increase in the thickness or width of the plant. This occurs due to the growth of lateral meristems i.e. the vascular cambium and cork cambium (in woody plants). Stem thickening occurs through the division of the vascular cambium located outside of the primary xylem and inside of the primary phloem. This division leads to the formation of the secondary xylem and phloem. The cells of the secondary xylem contain lignin and form the "woody" portion of the plant.
In woody plants, the cork cambium is the outermost lateral meristem and produces cork cells that provide strength and hardiness.
