Answer: cytokinesis
Explanation:
In animal cells, cytokinesis is achieved when a contractile ring of the cell microtubules form a cleavage furrow that divides the cell membrane into half.

Answer:
Sexuality education is more than the instruction of children and adolescents on anatomy and the physiology of biological sex and reproduction. It covers healthy sexual development, gender identity, interpersonal relationships, affection, sexual development, intimacy, and body image for all adolescents, including adolescents with disabilities, chronic health conditions, and other special needs.6 Developing a healthy sexuality is a key developmental milestone for all children and adolescents that depends on acquiring information and forming attitudes, beliefs, and values about consent, sexual orientation, gender identity, relationships, and intimacy.7 Healthy sexuality is influenced by ethnic, racial, cultural, personal, religious, and moral concerns. Healthy sexuality includes the capacity to promote and preserve significant interpersonal relationships; value one’s body and personal health; interact with both sexes in respectful and appropriate ways; and express affection, love, and intimacy in ways consistent with one’s own values, sexual preferences, and abilities.

Answer:
25% of the offsprings will be BBCC
Explanation:
This is a typical dihybrid cross involving two distinct genes. One coding for fur colour and the other for claw sharpness. The allele for brown fur (B) is dominant over the allele for black fur (b) in the first gene while the allele for sharp claws (C) is dominant over the allele for dull claws (c) in the second gene.
In a cross between parents with genotypes: BbCc x BBCC , each parent will produce four possible allelic combinations of gametes as follows:
BbCc: BC, Bc, bC, bc
BBCC: BC, BC, BC, BC
Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced with four distinct genotypes:
BBCC (4)
BBCc (4)
BbCC (4)
BbCc (4)
According to the question, an offspring that is homozygous dominant for both traits will possess a genotype: BBCC
N.B: Homozygous dominant means contains same alleles for the dominant trait.
Hence, offsprings with genotype, BBCC, from this cross are expected to be 4 out of the 16 possible offsprings. Hence, the percentage is 4/16 × 100 = 25%.
