We can explain Mr Mwape that variation in his children through Mendel’s law.
Reason why three children tall and brown one of MR Mwape was short and dark is: -
• Skin color and height is controlled by a lot of genes and every human gets one set of genes from their mother and the other set of genes from their father.
• Now imagine these genes are denoted as ‘T’ for tall and ‘B’ for brown and ‘t’ for short ‘b’ brown. We can assume that MR Mwape and his wife having genotype TtBb.
• During the process of gene segregation and assortment, the majority percentage of children got the heterogenous dominant genotype, which is ‘TtBb’, overlapping the effect of gene ‘t’ and ‘b’. While another child got a homogenous recessive genotype ‘ttbb’ from both the parents, hence the genotype is prominently shown in the fourth child and not in other as gene 't' and 'b' were dominated by genes 'T' and 'B'.

I would say C but In the integumentary system there are four main tissue types, those are Epithelial, Connective, Nervous and Muscular tissue
Answer:
Directly affects.
Explanation:
Climate, resources, and habitat size directly affect carrying capacity of an ecosystem. Favourable climatic and environmental conditions increases the population of organisms to its maximum limit. More resources leads to increase in population of species in an ecosystem until carrying capacity. Habitat size also depends on carrying capacity which means higher carrying capacity can leads to bigger habitat size. Climatic change, Habitat destruction, introduced and invasive species and genetic pollution are factors that effect both biodiversity and population. Human activities causes pollution, destruction of habitat by cutting trees etc affects biodiversity.
Answer:Movement is the change in the position of a body part with respect to the whole body.
