Carbonates + acid ----> water + salt + carbon dioxide
Answer:
The innate immunity in living organisms protects them from the pathogens they encounter daily.
Explanation:
Pathogens are organisms such as virus, fungi, bacteria, protozoa, worms that causes diseases to its host.
For example, Avian flu is a strain or variant of the Influenza virus which predominantly causes a disease in birds such as chickens. The virus responsible for the Avian flu can be passed from birds to humans; when anyone comes in contact with a bird that is carrying the virus i.e a sick bird with Avian flu.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment ideal to enhance life and proper functionality.
Also, immunization can be defined as the process of boosting an individual's immunity or immune system against antigens (immunogen) which cause diseases by the administration of vaccines.
Basically, immunization helps to improve the functions of the antibodies, B cells, T cells etc.
If a person becomes infected with a pathogen, such as a virus. The internal stimulus that mainly takes place in order for their body to maintain homeostasis is that their core temperature increases. This is because pathogens such as a virus do not thrive or survive in a hot environment; they're naturally allergic to high temperature (heat).
Because it can be a matter of our physical safety. In the wilderness a loud noise nearby is usually not a good thing. It is just natural instinct for the majority, if not all, species.
Answer and explanation;
Contraction of skeletal muscles;
-An action potential from a motor neuron triggers the release of Ca2+ ions from the sarcoplasmic reticulum.
-Calcium ions expose the myosin heads by binding to a blocking molecule (troponin complexed with tropomyosin) and causing it to move.
-The myosin heads form a cross-bridge with actin binding sites.
-ATP binds to the myosin heads and breaks the cross-bridge.
-The hydrolysis of ATP causes the myosin heads to change shape and swivel - this moves them towards the next actin binding site.
-The movement of the myosin heads cause the actin filaments to slide over the myosin filaments, shortening the length of the sarcomere.
-Via the repeated hydrolysis of ATP, the skeletal muscle will contract.
