Answer:
The probability of getting a dwarf and pink female is 1/2
Explanation:
In mice, dwarfism is caused by an X-linked recessive allele, and pink coat is caused by an autosomal dominant allele where coats are normally brownish.
A dwarf female from a pure line will have Xd Xd where d represent the recessive trait and the female is also brownish (pp).
A pink male from a pure line will be XPY where P represent the dominant allele but not a dwarf (D).

Answer:
Autotrophs are organisms that use light energy or energy stored in chemical compounds to make their own food.
1st order heterotrophs are organisms that eat only plants
2nd order heterotrophs are organisms that eat herbivores
3rd order heterotrophs: organisms that eat herbivores and other carnivores
Top group: carnivores
Explanation:
Producers are named as such because they produce their own food either by photosynthesis or chemosynthesis. These organisms are called autotrophs and include plants.
There are various levels of consumers. The first is first order heterotrophs, which feed on the producers. These are herbivores and include, for example, a deer feeding on grass.
The next is second order heterotrophs, which feed on the first order heterotrophs. E.g. an owl eating a mouse. These are carnivores
The next layer are also carnivores, third order heterotrophs which eat second order heterotrophs, for example a lion eating a zebra.
True.
Overlapping food chain is a food web. A food web shows the many different paths plants and animals are connected. eg: A hawk might also eat a mouse, a squirrel, a frog or some other animal.
