Ultrafiltration - The process of the filtration of blood in the glomerulus under great pressure during which the liquid part of the blood i.e. plasma along with urea, glucose, amino acids and other substances enter the renal tubule.

- The name Methane determines that the hydrocarbon is having only one carbon atom in its compound.
- If a hydrocarbon has only one carbon atom it is impossible to form double or triple bonds in that hydrocarbon.
- To form double bondage or triple bondage in the hydrocarbon there must be 2 carbon atoms in that hydrocarbon of least.
- But we can have only one carbon in the hydrocarbons.
- So there will be no Methene or Methyne existing on nature even if we alter or manipulate the compounds.

The hilum is basically a bundle of ‘tubes’ entering and exiting the kidney. The structures in this bundle include the renal artery that supplies the kidney with blood, the renal vein which drains blood from the kidney back to the inferior vena cava and then the heart, the ureter which conveys urine produced in the kidneys down to the bladder

ANSWER
A nephron is the basic filtration unit of the kidney. It is a cluster of thin-walled blood capillaries. There are different parts of the nephron in which the formation of urine take place which is the main function of the kidney.
- Bowman's capsule and the glomerulus are together called as the glomerular apparatus.
- There are afferent and efferent arterioles which bring and carry the blood way.
- The blood is filtered by the glomerulus and enters the Bowman's capsule where the podocytes help in the filtration and the glomerular filtrate is formed.
- When the glomerular filtrate comes to the proximal tubule then the essential nutrients are reabsorbed.
- There are two limbs of the loop of Henle, ascending and descending limb.
- The countercurrent exchange mechanism occurs which help in the regulation of the water and ions in the blood.
- When the glomerular filtrate is in the proximal tubule creatinine, uric acid are secreted in it.
- When the filtrate goes to the distal convoluted tubule urea, potassium ion and some hydrogen ions are secreted in it.
- The urine which is formed is transported by the collecting tubules to the renal pelvis.
- The urine is transported out by the ureters to the urinary bladder to store and excrete the urine from urethra.

voltage-drop is same across both
In parallel connection, all the elements are connected between same two points hence the voltage drop across any number of resistors or other elements connected in parallel is same.

Vegetative propagation is potentially something very unique to plants. The very same attribute is also used for the commercial value and by ardent gardeners who know their plants well. Seeds are not always essential for plants to grow. Vegetative propagation such as grafting and budding, etc. help in growing new plants from vegetative parts of the older plants. It is an asexual method of reproduction. In vegetative reproduction, morphologically and the genetically identical offspring is produced.
Advantages Of Vegetative Propagation
- Vegetative reproduction has several benefits, primarily because the developed offspring represent copies of their parent plants. If a plant has positive features, the genetic information can be passed on to its offspring.
- Commercial growers may profit by cloning such plants in order to ensure their crops remain compatible financially.
- Vegetational propagation often helps plants in the development of *** organs such as flowers and eventual seeds and fruit to avoid costly and complicated processes. In other terms, as farmers grow the ideal characteristics in apples, they use grafting and birth to ensure that the new variety and its productive production are compatible at the trade level. This does not always occur though, as can be seen in many different plants since many plants are a chimera and the cuttings will represent the characteristics of only one or some of the cellular parent lines. Plants can also skip the intermediate process of seedling and enter the mature stage more rapidly.
- It increases the chances of a plant reaching maturity effectively in nature and saves growers a great deal of time and money on a commercial basis as it permits a quicker overturn.
- Vegetative reproduction offers scientific opportunities in several biological fields and is realistic in the context of afforestation. The most frequent use of forest geneticists and tree breeders in vegetative propagation has been to move genes from selected trees to a convenient location, typically a gene bank, a clone bench, a cloning orchard or seed garden where genes can be recombined with pedigrees.

- Budding is the asexual mode of reproduction. In budding, a genetically identical new organism grows attached to the body of parent <i>Hydra </i>and separates later on.
- In the process of budding, a bud develops as an outgrowth due to repeated cell division at one specific site. This bud grows randomly and there is no specific order or direction they follow.

The heart receives deoxygenated blood from different parts of the body, and it pumps this blood to the lungs. The oxygenated blood from the lungs returns to the heart, which is pumped again into different parts of the body by the heart. Thus, the blood passes twice through the heart making one complete round through the body. This is called double circulation.
Pulmonary and systemic circulation
The pulmonary circulation pertains to lungs. The blood flows from the right ventricle to the lungs. Pulmonary veins collect oxygenated blood from the lungs and carry it back to the heart (left auricle).
The systemic circulation pertains to the major circulation of the body. The aorta receives the blood from the left ventricle and sends it to the various parts of the body. Veins collect the deoxygenated blood from the body parts and pour it back into the right auricle.

Structure of forelimb in a frog, lizard, bird and horse is similar with similar bones which are modified to suit the function they perform. From this it can be safely assumed that they may have evolved from a common ancestor.

The placenta is an organ that links the budding fetus to the uterine wall to facilitate the uptake of nutrients, gas exchange and waste elimination, with the help of the mother's blood supply. The umbilical cord connects the fetus to the placenta.
The placenta is a spongy mass of flesh that absorbs oxygen and nutrients from the blood stream of the mother, which are then transferred to the baby via the umbilical cord. The umbilical cord is responsible for carrying the oxygen and nutrients to the fetus.
The placenta is discarded after the baby's delivery, while a portion of the umbilical stump still remains on the baby, but soon withers away as well.

The magnitude of electric current is measured in coulombs per second. The SI unit of electric current is Ampere and is denoted by the letter A. Ampere is defined as one coulomb of charge moving past a point in one second. If there are 6.241 x 1018 electrons flowing through our frame in one second then the electrical current flowing through it is ‘One Ampere.’
The unit Ampere is widely used within electrical and electronic technology along with the multipliers like milliamp (0.001A), microamp (0.000001A), and so forth.

i. Take small quantity of quick lime (CaO) in a beaker.
ii. Slowly add water to thequick lime (CaO) taken in the beaker.
iii. Touch the beaker with fingers and make a note of the change in temperature.
Observations:
i. Quick lime reacts vigorously with water producing hissing sound.
ii. Beaker becomes hot.
Inferences:
Quick lime (calcium oxide) reacts with water vigorously to form calcium hydroxide and releases large amount of heat.
It is an example of a combination reaction as well as an exothermic reaction.

Any visible movement such as walking, breathing, or growing is generally used to decide whether something is alive or not. However, a living organism can also have movements, which are not visible to the naked eye. Therefore, the presence of life processes is a fundamental criterion that can be used to decide whether something is alive or not.
Evidence which can ensure something is alive or not
- Shape and Dimension
- Reproduction
- Growth
- Cellular structure
- Metabolism
- Movements
- Self-regulations
- Variation
- Co- ordination
- Definite life cycle
- Death
Example – Movements are fast in most animals but motions in plants are generally slow.
