Answer:
The correct option is: 4. Heat at 62.8 degrees C for 30 minutes
Explanation:
Pasteurization is the process or technique of heating packaged as well as the unpackaged liquid food, to remove pathogens and extend the shelf life. In this process,<u> the food is usually heated at temperatures below 100 °C.</u>
Originally, this process involved heating the food at 72.2 °C for 15 seconds and <u>62.8 °C (145 °F) for 30 minutes, for batch pasteurization.</u>
If it’s a yes or no question then yes because they spread through organisms. there are many organisms in the water that bacteria can spread through
The variation in beak type enables the different individuals in a population to feed on different food sources.
The shape of the beak is key to determining the primary food source of the bird. Certain birds species have specialized beaks, but within populations of those species, there is a variation in beak shape.
This gives the population the ability to respond to changes in the environment and availability of different food sources.
For example, if because of a dry period there is a shortage of fruit, some individuals in the population have the beaks that enable them to feed on other things, survive and leave offspring.
Answer:
Continental crust is typically 40 km (25 miles) thick, while oceanic crust is much thinner, averaging about 6 km (4 miles) in thickness. The effect of the different densities of lithospheric rock can be seen in the different average elevations of continental and oceanic crust.
Explanation:
<u>Answer</u>:
The skull of a bird looks similar to that of a young dinosaur when they are at their embryo stage.
<u>Explanation</u>:
Bird's skull at their embryo stage looks like young dinosaur's skull. This feature gives evidence of their evolution and their ancestors. The surviving member of the feathered dinosaur family are the birds. The unique skull shape of a bird shaped like a beaker with a dome like cranial resembles with the non-flying ancient dinosaurs. This phenomenon is often named as psuedomorphism. In this phenomenon, these features of the ancestor at its embryo stage is retained by its predecessors.
