4 0

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>

What is a good description for the cell wall?
Ipatiy [6.2K]

The cell wall is the protective, semi-permeable outer layer of a plant cell. A major function of the cell wall is to give the cell strength and structure, and to filter molecules that pass in and out of the cell. A cell is the smallest part of an organism that still contains that organism's elements.

What is a european starlings ecological role
makkiz [27]
European Starlings have a significant impact on their environment because they congregate in such large numbers.  They probably play a role in seed dispersal because of their consumption of a wide variety of fruits.  European Starlings also control some insect populations, but since they will eat almost anything they cannot be relied upon to eat only pests.  Insects they are known to feed on include the larvae of craneflies (Tipulidae) and moths (Lepidoptera) as well as mayflies (Ephemeroptera), dragonflies and damsel flies (Odonata), grasshoppers (Orthoptera), earwigs (Dermaptera), lacewings (Neuroptera), caddis flies (Trichoptera), flies (Diptera), sawflies, ants, bees and wasps (Hymenoptera) and beetles (Coleoptera).  They will also eat small vertebrates such as lizards and frogs, as well as snails (Gastropoda) and earthworms (Annelida).  European Starlings have a particular technique of inserting their closed bill into the ground or an object and then prying the bill open, creating a small hole.  This allows them to forage efficiently in soil and among roots as well as in feed troughs and on the backs of ungulates where they search for ectoparisites.

What type of membrane proteins are integral proteins that move ions or molecules across plasma membrane?
blsea [12.9K]

Answer:

Channel proteins and Carrier proteins

Explanation:

These are type of membrane proteins that transcend the entire length of  phosphoslipid  bi- layer  in the plasma membrane.They facilitate the movement of ions  and molecules across  the walls of the plasma membranes.

Generally, substances like glucose, amino acids, are too large to pass through the phopholipid bilayers. Likewise ions of  potassium, sodium calcium, because of their polarities can not pass through either. They are ferried across the phospholipid by  group of protein structures called channel proteins. Some are also transported across by carrier  proteins.  The process by which these protein structures  aided the  diffusion of substances across the phospholipid bilayer is called Facilitated diffusion.

Channel proteins are pores, that are filled with water molecules with the entrance  well gated.  That is the entrance  is controlled by part in the inner structure  of the protein  which can open or close the pores  like a gate to control the movement of ions across it. e.g Sodium channels are gated for  movement  of sodium ions by voltage or ligands(chemicals) during  nervous  transmission to elicits action potential. Like wise Potassium channels allow  diffusion of potassium ions across the phospholipid bilayers. it gates are shut when sodium channels are open; this  regulate ion exchange.

Their structures are well fixed in shape , specific  to the substance or ions being  transported;and the rate of diffusion  depends on  the like hood of opening of the gate or closure.

Carrier molecules  also in the membranes  do not have a fixed shape, and their transport  direction is determined by the direction of concentration gradients. Thus they can flip on either sides of the membranes to aid diffusion across. Their movement can  be both passive and active, and the rates  of diffusion depends on the number of available carrier proteins in the membrane. They are also specific to the ions they transport.And are not gated,

Therefore these two membrane integral  proteins  facilitate movements of substances across the phospholipild bilayers
