nexus9112 [7]

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).

Wittaler [7]

Answer:

the order would be:

Carnivorous animal -> scavenger animal ---> autonomous living organism ---> decomposing organisms.

Explanation:

The lion would be the carnivore, the bird that eats the waste of dead meat would be the scavenger, the vegetable the autonomous, since it does not require an external energy source to live but synthesizes its own energy and finally the decomposers fulfill the function to decompose chemical compounds to give energy to the earth, which would be useful for the growth of other living organisms. This is how the chain meets the cycle of life.

You are working in an emergency care center. a person comes in dehydrated and the doctor orders a hypertonic solution. explain w
andrezito [222]
Dehydration is the loss of too much water in our body  It can be categorized into three types: isotonic, hypotonic and hypertonic. Isotonic dehydration is the most common, which pertains to equal concentrations of the extracellular and intracellular fluids. In this type of dehydration, about same amount of electrolytes and water are ;pst from the body. Hypertonic dehydration is more serious and a very risky IV fluid to administer. This type of dehydration occurs when more electrolytes are lost than water from the body. So, there must be an intake of a fluid more concentrated in electrolytes so that it will cause the water from inside the cells to be attracted to the extracellular fluid. The last type of dehydration, hypotonic dehydration, is the opposite of hypertonic. This is when more of water is lost than electrolytes. So, the fluid to be administered is less concentrated relative to the fluid inside the cells.
