Answer: By definition, if the atomic number =
7
, then there are 7 protons, 7 electrons, and 8 neutrons!
Explanation:
The atomic number is by definition the number of protons, positively charged particles, contained within the atomic nucleus. So if there are 7 protons, there MUST be 7 electrons, 7 negatively charged particles. Why? Because matter is electrically neutral, and positive and negative particles must be equal.
Electrons have negligible mass; the mass number depends on the number of protons contained within the nucleus, PLUS the number of neutrons. Given that we have 15 N
, there must be 8 neutrons contained within the nucleus. does this help?
Answer:
a. It's a carrier protein doing facillitated diffusion
Explanation:
Facilitated diffusion may be defined as the transportation of molecules from a high concentration to a low concentration that is down the concentration gradient without input of the energy. Whereas the active transport is transportation of the molecules from the low concentration to the high concentration which is against concentration gradient by the membrane protein.
The glucose transportation process requires membrane protein for the transport and does not require any energy. Therefore, it is carrier protein which is doing the facilitated diffusion.
While cooked rice meals are associated with the vomiting ailment, cooked veggies, animal products, and milk are frequently linked to the diarrhea ailment (rice pudding and fried rice). The easiest way to avoid it is to regulate the temperature and time.
<h3>What is meant by "foodborne disease"?</h3>
Foodborne illness is brought on by consuming contaminated foods or beverages. Foodborne infections can result from a wide variety of pathogens or disease-causing germs contaminating foods. Foodborne illnesses are typically caused by bacterial, viral, and parasite infections.
<h3>What are the 5 major foodborne illnesses?</h3>
- Norovirus.
- Salmonella.
- Clostridium perfringens.
- Campylobacter.
- Staphylococcus aureus
<h3>What brings about food-borne illness?</h3>
Foodborne illness causes
Bacteria, viruses, and parasites are biological risks. Most foodborne infections are caused by bacteria and viruses. The greatest danger to food safety is posed by biological risks. They may be a result of improper handling (such as using excessive time or temperature) or inherent in the product.

Explanation:
Water molecules from the less conentrated right side, will flow into the left side til they equilibrate- at equilibrium both sides will have the same concentration of solute.
In diffusion small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. Similarly, during osmosis the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid bilayer, this means that the water moves from regions of high osmotic pressure/concentration to regions of low osmotic pressure /concentration.
