The first law of energy can be applied in food processing whereby foods are converted from one form to another.

Food processing is the process by which food is converted from its natural state obtained from plants to a more edible and palatable state for consumption by humans.

The first law of energy states that energy cannot be created nor destroyed but can be converted to other forms.

Therefore, the first law of energy can be applied in food processing whereby foods are converted from one form to another.

Viruses are organisms that share traits with both living and non-living organisms. The virus' genetic material is made up of both DNA and RNA.

Viruses have an exterior capsule layer and a specified boundary. Only the host cells provide energy to the virus. They thrive and mature, multiplying their numbers solely within the host cells.

A virus is a single-celled with no more than one cell. In the virus, there is no internal organization. If a virus is present outside of the host environment, it does not grow, develop, or require energy. Viruses do not remove trash.

Water has a remarkable ability to cling to itself and other substances. The propensity of water molecules to be attracted to other water molecules, allowing water to be a "sticky" liquid, is described by the property of cohesion.

The difference in charge between slightly positive hydrogen ions and other, slightly negative ions causes hydrogen bonds, which are electrostatic forces.

Hydrogen bonds form between adjoining hydrogen and oxygen atoms of adjacent water molecules in the case of water. A hydrogen bond is formed when individual water molecules attract each other.

The nephron is the filtration unit of the kidney.

It consists of a tubule that is connected with collecting duct at one end and a cup-shaped structure at the other end. This cup-shaped structure is called ‘Bowman’s capsule’. Every Bowman’s capsule contains a cluster of capillaries, called ‘Glomerulus’, within the cup-shaped structure. The blood enters into Glomerulus through afferent arteriole of the renal artery and leaves it through the efferent arteriole. Together, the glomerulus and its surrounding Bowman's capsule are called a renal corpuscle.

Blood enters the glomerulus through a small artery supplying the glomerulus with unfiltered blood called the afferent arteriole. Another vessel, a small artery carrying filtered blood away from the glomerulus, is called the efferent arteriole. These two arterioles play a key role in helping the glomeruli's capillaries perform the process of ultrafiltration.

Nephron starts from Bowman’s capsule and consists of the following parts: proximal convoluted tubule (in the renal cortex), the loop of Henle (in the renal medulla), and distal convoluted tubule (in the renal cortex).

i) proximal convoluted tubules (PCT): it is a proximal part of renal tubules next to Bowman’s capsule. It is lined with microvilli. Maximum reabsorption of water, glucose, amino acids and electrolytes takes place here.

ii) The loop of Henle: It is U shaped middle portion of renal tubules. It is composed of ascending and descending loop. Ascending loop is thick-walled and impermeable to water while the descending loop is thin-walled and permeable to water. The countercurrent mechanism is a crucial role of the loop of Henle.

iii) Distal convoluted tubules (DCT): It is the distal part of renal tubules that lead to collecting ducts. It is similar in structure and function with PCT. Functioning of Nephron:-

1. Filtration: Filtration of blood takes place in Bowman’s capsule from the capillaries of the glomerulus. The filtrate passes into the tubular part of the nephron. This filtrate contains glucose, amino acids, urea, uric acid, salts and a major amount of water.

2. Re-absorption: As the filtrate flows along the nephrons, substances such as glucose, amino acids, salts, and water are selectively re-absorbed into the blood by capillaries surrounding the nephron tube the leadule.

The amount of water re-absorbed depends on the need of the body and also on the amount of wastes to be excreted.

3. Urine: The filtrate which remains after re-absorption is called urine. Urine contains dissolved nitrogenous waste, i.e. urea and uric acid, excess salts and water. Urine is collected from nephrons by the collecting duct to carry it to the ureter.

Filtration: Blood filtration is takes place in Bowman’s capsule from the capillaries of the glomerulus.

Reabsorption: When blood filtrate flows along the nephrons, molecules  of amino acids, salts, glucose, and water are by selection re-absorbed into the blood by capillaries.

Secretion:  hydrogen ions and waste ions flows from the capillaries into the renal tubule, this process is known as secretion.

Answer:

0.315 hectares

Explanation:

To get the answer, we use the area of a trapezium formula, which is ½ (a+b) h, where a and b are the parallel sides and h is the height.

So ½(90m+50m) 45m

½ × 140 × 45

70 × 45 = 3150m²

10000m²= 1hectare

3150m² = x

3150 ÷ 10000 = 0.315 hectares.

Answer: Option (A)

Explanation:

The interior of the earth radiates a huge amount of energy due to the presence of molten heavy materials namely iron and nickel. This heat energy drives the plates to move over the mantle.

This radiated energy plays a significant role in increasing the temperature at the lower atmosphere. At the lower atmosphere majority of the air is concentrated due to its high density and are attached to the ground because of gravity.

This radiated heat energy then heats up this air particles that leads to an increasing air pressure and temperature.

The difference in an area with high concentration and an area with low concentration is called concentration gradient.

Concentration gradient refers to the difference between the concentrations of two solutes in a solution.
