Answer:

Haemoglobin; liver; binds; stored; bile duct; small intestine; lipids.

Explanation:

Serology can be defined as the study of blood and the reactions between antibodies and antigens in the blood.

In Biology, blood pH can be defined as a measure of the hydrogen ion (H¯) concentration of blood i.e the level of alkalinity or acidity of blood.

Basically, the normal blood pH of a human being should be between 7.35 and 7.45.

Hence, one of the ways in which the body regulates blood pH is with proteins. Proteins help regulate blood pH by accepting and releasing hydrogen ions. Typically, when the blood pH falls, the hydrogen ions (H¯) are accepted (absorbed) while hydrogen ions are released when the blood pH rises.

For example, a protein such as haemoglobin which makes up a composition of the red blood cells, binds an amount of acid required to regulate blood pH.

In the spleen, haemoglobin from red blood cells is broken down to form (unconjugated) bilirubin. Unconjugated bilirubin is insoluble in blood plasma so binds to albumens in the blood and is sent to the liver. Bilirubin binds with glucuronic acid to form conjugated bilirubin. It forms part of the bile, which is stored in the gall bladder. Food in the gut stimulates gall bladder contraction and the bile passes down the bile duct to the small intestine, where it aids in the digestion of lipids.

Mushrooms are in kingdom Fungi and humans are in kingdom Animalia

Explanation:

These two kingdoms are similar in that they are both in Domain Eukarya, meaning they have eukaryotic cells (have a nucleus, membrane bound organelles, are relatively large and organized). Both are also heterotrophic, meaning they eat other organisms to get energy. They are different in that fungi cells have cell walls made of chitin while animals do not have cell walls. Fungi tend to live pretty sedentary lives, and while that is true for some animals, that is not true of most. Fungi are also decomposers while animals are consumers.

Hardwired characteristics of the brain that attempt to keep us in balance by correcting deficiencies are referred to as homeostatic mechanisms.

Homeostasis is the body's ability to maintain a stable internal environment despite external changes.

In the context of the brain, homeostatic mechanisms involve various processes that regulate physiological functions and maintain optimal levels of essential substances.

These mechanisms can include feedback loops that detect imbalances and initiate corrective actions.

For example, if there is a deficiency in a particular nutrient or hormone, the brain may activate mechanisms to increase its production, decrease its consumption, or enhance its absorption from the environment.

Homeostatic mechanisms play a crucial role in ensuring the body's overall stability and functioning, helping to maintain proper levels of various substances and promoting overall well-being.

The tube responsible for equalizing pressure between the middle ear and the nasopharynx is called the Eustachian tube.

This tube helps to regulate pressure in the middle ear and prevent damage to the eardrum when there are changes in altitude or pressure. Essentially, the Eustachian tube allows for the passage of air between the middle ear and the outside environment, which helps to equalize pressure on either side of the eardrum. This is why you may feel the need to "pop" your ears when you are flying in an airplane or driving up a mountain - it's your body's way of equalizing pressure in the middle ear via the Eustachian tube.

The process can be explained as follows:

1. When you change elevation, the air pressure outside your ear changes as well.
2. The Eustachian tube allows air to flow between the middle ear and nasopharynx.
3. This airflow helps to equalize the pressure between the middle ear and the outside environment.
4. As a result, you experience less discomfort or pain when there is a sudden change in altitude, such as during air travel or climbing a mountain.

So, the Eustachian tube is responsible for the equalization of pressure when you change elevation, ensuring your ears remain comfortable and functional.

The major evolutionary innovations in the hominin lineage that defined and continue to define Homo sapiens sapiens include bipedalism, increased brain size and complexity, tool use and cultural development, and the emergence of language and symbolic thought.

Bipedalism, or the ability to walk upright on two legs, is a defining characteristic of hominins, including our species. This transition from quadrupedalism to bipedalism allowed for more efficient movement and freed the hands for tool use and manipulation. Alongside bipedalism, there was a significant increase in brain size and complexity throughout the hominin lineage, culminating in Homo sapiens sapiens, enabling advanced cognitive abilities, problem-solving, and social interaction.

Tool use and cultural development were significant innovations that shaped the hominin lineage. The development and refinement of tools allowed for resource exploitation, hunting, and adaptation to different environments. The transmission and accumulation of cultural knowledge through generations became increasingly important.

Answer: splitting of water + pumping of hydrogen across that thylakoid membrane.

Explanation:

The sources of Hydrogen in the thylakoid are- Pumping of hydrogen across the thylakoid membrane; Splitting of water molecule. Thus, the correct options are 2 and 3.

Photosynthesis is the process through which plants make their food. This process takes place in the chloroplast of plant cell. The chloroplast contains Photosystems- PSI and PSII which are responsible for photosynthesis. The hydrogen ions required by the plants are obtained by the Photolysis (splitting of water molecules) to release oxygen and hydrogen. This occurs in photosynthesis. i.e., photosystem-II.

To replace an electron in the reaction center in PSII, a molecule of water is split. This releases an electron and results in the formation of oxygen (O2) and hydrogen ions (H+) in the thylakoid space.

The hydrogen ions are pumped actively through ATP synthase. This uses up ATP energy and causes the production of ADP and phosphate. The Ubiquitin protein present in the membrane is the carrier for hydrogen ions.

Therefore, the correct options are 2 and 3.
