Question

What prediction(s) can researchers make based on the egg-viability hypothesis? select all that apply. what prediction(s) can researchers make based on the egg-viability hypothesis? select all that apply. the probability of hatching failure will be higher for eggs laid later within a clutch. the probability of hatching failure will be lower at higher latitudes. the probability of hatching failure will be higher later in the spring season. the probability of hatching failure will be higher in large clutches?

Answer 1

Prediction that the researcher can draw based on the egg viability hypothesisare that the hatching failure probability will be lower at higher latitude, the hatching failure probability will be higher in the spring season, the hatching failure probability will be higher in the large clutches.

Further Explanation:

Many birds begins the incubation prior to the completion of their clutch, this leads to a synchronous development and hatching of eggs. This may also results in their mortality of the smallest chicks. The early incubation may have a functional significance as it is involved in protection of eggs from brood parasitism or in maintaining the viability of early eggs. The viability hypothesis states that the parents of the birds maximizes the hatchability of eggs by starting the incubation process prior to the completion of clutch as the viability decreases over the time.

Factors that affects the hatchability of unincubated eggs are:

1. Temperature
2. Humidity
3. Gaseous environment
4. Egg orientation
5. Egg turning

Prediction that the researcher can draw based on the egg viability hypothesis are:

1. The hatching failure probability will be lesser at higher latitude.
2. The hatching failure probability will be more in the spring season.
3. The hatching failure probability will be more in the large clutches.

The temperature is the most crucial condition that affects the hatchability of unincubated eggs. Overheating causes the death of the embryo

Answer 2

This is because eggs "keep" at cooler temperatures.There are three answers that researchers can predict based on the egg-viability hypothesis.
first is the probability of hatching failure will be lower at higher latitudes.
second is the probability of hatching failure will be higher later in the spring season. 
third is the probability of hatching failure will be higher in large clutches
