Compact bones are the strong, outer layer of bones that make up 80% of the bone's weight whereas spongy bones are weak, and make up 20% of bone's weight.

Compact bones, also known as cortical bones, are bones that are denser and harder than spongy bones. Compact bones make up the outer layer or cortex of long bones, such as the femur, and are composed of a matrix of collagen fibers and hydroxyapatite crystals. These bones are strong and provide protection for the internal structures and organs of the body. Compact bones also provide support and movement while protecting us from injury.

Spongy bones, also known as cancellous bones, are bones made up of a network of spaces filled with red bone marrow. Spongy bones are usually found in the ends of long bones and are important in providing blood cells, which support the entire body's functions. Unlike compact bones, spongy bones have a lower mass-to-surface area ratio and therefore absorb shock and vibrations better. Spongy bones are also known for their ability to easily remodel in response to stress, allowing them to adapt to an individual's daily activities.

When a protein source reaches your stomach, hydrochloric acid and proteases enzymes convert it into smaller chains of amino acids.

Peptides, that are broken down by proteases, are also what link amino acids. These smaller chains of amino acids go from your tummy to your small bowel.

However, protein is broken down into ketone bodies to be utilised for energy if the body is not acquiring enough calories from other foods or from the fat stored in the body. The body breaks down excess protein and stores its constituent parts as fat if it is ingested.

Consumed protein is converted to amino acids by the body and then absorbed. It is utilised in the development of muscles and organs, the production of hormones and antibodies, the storage of fat, and the production of energy.

The small intestine is where protein digestion finishes after starting in the stomach. A stomach enzyme called pepsin starts the breakdown of proteins.

The protein indicated by a question mark in the figure depicting the steps of the common pathway of coagulation is thrombin.

When coupled to thrombomodulin, thrombin activates Protein C, a coagulation cascade inhibitor. After thrombin binds to thrombomodulin, a key membrane protein produced by endothelial cells, protein C activation is significantly increased. Factors Va and VIIIa are rendered inactive by activated protein C. Protein S's activity is somewhat increased when active protein C interacts to it. Antithrombin, a serine protease inhibitor, also renders thrombin inactive.

It is TRUE that the characteristics of an organism are rooted in the activities of cells, which are in turn encoded by genes.

Genes are sections of DNA that contain instructions for making proteins, which serve as the skeleton of cells. Gene expression and protein synthesis are influenced by a variety of variables that control the activity of genes, including internal signaling pathways and external signals. The interactions between several genes and their byproducts, as well as different environmental conditions, result in complicated biochemical processes that drive cellular activities. The morphology, physiology, behavior, and reaction to the environment of the cell and the organism as a whole are all determined by these processes.

The properties of the organism can vary as a result of changes in cellular activities brought on by changes in the genetic code, such as mutations or changes in gene expression. As a result, an organism's traits are dictated by the actions of its cells, which are governed by the genes that are encoded in its DNA.

The actual question is:

True, or False,

The characteristics of an organism are rooted in the activities of cellular encoded by genes.

Answer: If there are more than one type of colony morphology on a serial dilution plate, it could mean that there are multiple species or strains of microorganisms present in the sample. It could also indicate that there was contamination during the sample collection or processing, leading to the growth of multiple microorganisms with different characteristics.

Alternatively, it is possible that a single species of microorganism has developed different colony morphologies due to genetic variation or environmental factors. In this case, further investigation may be necessary to determine if the different colony morphologies are indeed from the same species.

This process is based on a chemical reaction that occurs when the warm exhaust gases from the coal-fired boiler come into contact with limestone.

When the warm gas comes into contact with the limestone slurry a chemical reaction occurs between the Sulphur Dioxide (SO2) in the gas and the limestone.

This reaction removes the SO2 from the flue gases and converts the limestone into Calcium Sulphite.

Explanation:

At the end of meiosis I, each chromosome still consists of two sister chromatids, but the number of chromosomes is reduced by half.

This reduction is due to the separation of homologous chromosomes, which are pulled to opposite poles of the cell during the first division. At the end of meiosis II, the sister chromatids finally separate, resulting in four haploid daughter cells, each containing a single chromosome. So, at the end of meiosis II, the chromosomes are in their haploid form, with only one chromatid per chromosome. In summary, the chromosomes at the end of Meiosis I are still composed of sister chromatids, while the chromosomes at the end of Meiosis II are single chromatids in each of the four haploid cells.

The H+ ion that has just passed through the inner mitochondrial membrane by diffusion is H+ ion from the intermembrane space.

Mitochondria are known as the powerhouse of the cell, which is where energy is produced in the cell. They are responsible for converting nutrients into energy through the process of cellular respiration. Through this process, the energy produced in the mitochondria is used by the cell to perform its functions.

The electron transport chain is a series of molecules found in the inner membrane of the mitochondria. It is responsible for the production of ATP, which is the primary energy source for the cell. During the ETC, electrons are transferred from one molecule to another, releasing energy that is used to create a proton gradient. This gradient is then used to generate ATP.The H+ ion from the electron transport chain is transferred from one molecule to another in the ETC and does not pass through the inner mitochondrial membrane by diffusion.

H+ ion from the cytoplasm is not produced in the mitochondria, so it does not pass through the inner mitochondrial membrane by diffusion. H+ ion from the matrix is produced in the mitochondria and is used in the ETC to create a proton gradient, but it does not pass through the inner mitochondrial membrane by diffusion.

Our total body weight accounts for about 7 to 8 % of blood. Blood is a mixture of around 55 percent plasma and 45 percent blood cells. Blood running through the veins, arteries and capillaries is called whole blood.

How does the blood change as it flows through the respiratory system?

Blood circulatory system, also called the cardiovascular system, delivers oxygen and nutrients to all the cells of the body.

The respiratory system consists of the respiratory passage and respiratory organ, that is the lungs.

Blood is carried to the lungs through the pulmonary arteries where it picks up oxygen. The blood then leaves the lungs and returns to the heart via the pulmonary vein. It then enters the left atrium. The blood then drops into the left ventricle through the mitral valve.

Transport of gases also occurs through blood.

For exchange or oxygenation, the deoxygenated blood is transported to the lungs from heart. Carbon dioxide is exchanged with oxygen as the blood flows through the respiratory system. For further circulation to various body parts, oxygenated blood is then transported to the heart.

Some amount of gases get dissolved in the blood plasma and get transported, whereas some amount of them is transported in the bound state.

To increase blood flow by a factor of 10, the radius of an artery needs to be increased by approximately 3.16 times due to the fourth power relationship between blood flow and radius.

Angioplasty is a technique that involves dilating partially blocked arteries to improve blood flow.

To increase blood flow by a factor of 10, the radius of an artery must be increased by a factor of approximately \(3.16 (10^{(1/4)})\). This is because blood flow is directly proportional to the fourth power of the radius according to Poiseuille's law.

By increasing the radius, the cross-sectional area of the artery expands, allowing for a greater volume of blood to flow through it.

An increase in salt intake will lead to all these changes except **increased urinary sodium loss**. When salt intake is increased, it triggers several physiological responses in the body.

Firstly, increased salt intake can lead to an **increased aldosterone secretion**. Aldosterone is a hormone produced by the adrenal glands that regulates sodium and potassium balance. Higher salt intake stimulates the release of aldosterone, which promotes sodium reabsorption in the kidneys and excretion of potassium. Secondly, an increase in salt intake can result in an **increased extracellular fluid (ECF) volume**. The excess sodium in the body causes water retention, leading to expanded ECF volume. This is because sodium has an osmotic effect, drawing water into the extracellular space. Lastly, an increase in salt intake promotes **increased sodium uptake** by the body. The excess sodium consumed is absorbed in the gastrointestinal tract and distributed throughout the body via various transport mechanisms. However, the statement that is not true is **increased urinary sodium loss**. When salt intake is increased, the body tends to retain more sodium to compensate for the excess intake. This leads to decreased sodium excretion in the urine, rather than increased sodium loss.
