Systolicblood pressure, the number on the top and (hopefully) the higher number, is the amount of pressure in the arterieswhenthe heart beats i.e when the right ventricles sends blood to the lungs, and when the left ventricle sends blood to the body tissuesDiastolicblood pressure, the number on the bottom, is the amount of pressure in the arteries between heart beats, when the heart fills with the blood it is about to pumpThe reason the two numbers differ is because arteries are under much more pressure when they are pumping blood out

The recycling of paper is the process by which waste paper is turned into new paper products. It has a number of important benefits besides saving trees from being cut down. It is less energy and water intensive than paper made from wood pulp. It saves waste paper from occupying landfill and producing methane as it breaks down. Around two thirds of all paper products in the US are now recovered and recycled, although it does not all become new paper. After repeated processing the fibers become too short for the production of new paper

Sexual reproduction is the production of new living organisms by combining genetic information from two individuals of different types (sexes). In most higher organisms, one sex (male) produces a small motile gamete which travels to fuse with a larger stationary gamete produced by the other (female).

Macro-nutrientsare those nutrients which are required in large quantities for growth and development of plants. Sincetheyare required in large quantities,theyare known asmacro-nutrient. The sixmacro-nutrientsrequired by plants are nitrogen, phosphorus, potassium, calcium, magnesium, and sulphur.

Crop rotation

It prevents soil depletion,increases soil fertility,reduces soil erosion and the need for fertilizers.It also helps in controlling weeds and controls the growth of pathogens and pests in crops.

Intercropping:

1. Intercropping gives higher income per unit area than sole cropping. 2. It acts as an insurance against failure of crop in abnormal year. 3. Intercrops maintain soil fertility as the nutrient uptake is made from both layers. 4. Reduce soil runoff.

Blood is the main component of the human circulatory system. The main functions of blood include:

Regulates the body temperature.

Regulates the water content of the cells.

Protects against excess loss of blood through clotting.

Regulates the pH by interacting with acids and bases.

Involved in the transportation of gases, enzymes, nutrition,hormonesand other molecules to the respective parts of the body.

While apes andmonkeysare bothprimates, and are part of the same primatesuborder, there are lots of differences between them. There are also lots of other sorts of primates. The distinction between different primate groups is­ based on physical characteristics andevolutionaryancestry.

Theorderof primates is characterized by animals with forward-facingeyesand highly flexible arms, legs and fingers. This body structure evolved as an adaptation for life in the trees: Primates have flexible limbs and grasping hands so they can move from branch to branch. The forward-facing eyes are also an adaptation for life in this environment: They give primates excellentdepth perception, allowing them to accurately judge the distance between trees.

It is only a temporary relief. It's true that milk can temporarily buffer stomach acid, nutrients in milk, particularly fat, may stimulate the stomach to produce more acid. While this practice may temporarily decrease stomach acid, it does not treat the underlying cause of the acid reflux.

The air quality index (AQI) rating for Jalandhar was the worst in Punjab, making it the most polluted city, the day the Continuous Ambient Air Quality Monitoring Station (CAAQMS) was inaugurated in the city.

The average AQI in Jalandhar was recorded at 260, placing the city in the “poor” category. An AQI range between 0 and 50 is rated as “good” and “moderate” if between 50 and 100. The machine was installed at the Circuit House to measure real-time ambient air quality. The other cities that already have a monitoring station are Amritsar, Ludhiana, Mandi Gobindgarh and Patiala. The AQI rating of all these cities was way lower. The average AQI in Jalandhar was 260 (out of 500), in Amritsar 143, Ludhiana 114 and Patiala 101.

WHO data shows 14 Indian cities are among 20 most pollutedNine out of 10 people on the planet breathe polluted airToxic air kills 7 million each year, mostly in Asian, African nationsNew Delhi, Gwalior, Varanasi and Kanpur were among the 14 Indian cities that figured in a list of 20 most polluted cities in the world, based on their toxic air quality, data released by World Health Organization showed. On PM 2.5, most polluted city is Varanasi, Prime Minister Narendra Modi's constituency. Major sources of air pollution from particulate matter - pollutants like sulphate, nitrate and black carbon - include inefficient use of energy by households, industry, agriculture and transport sectors, and coal-fired power plants. The study found that "around seven million people die every year from exposure to fine particles in polluted air".

The type of plastids which help in photosynthesis is called chloroplasts.

The plastid which helps in photosynthesis is called as chloroplasts. It is one of the most known of the plastids found in leaves of plants. Chloroplasts are responsible for the photosynthesis process and they are mainly filled with thylakoids.

Thylakoids are the place of photosynthesis. So we can say that they are the place for the pigments to be stored and synthesized in the plant.

The general principles of anoxygenic and oxygenicphotosynthesisare very similar, but oxygenicphotosynthesisis the most common and is seen in plants, algae and cyanobacteria. During oxygenicphotosynthesis, light energy transfers electrons from water (H2O) to carbon dioxide (CO2), to produce carbohydrates.

protoplasts, leucoplastscromoplasts anb cloroplasts

There are four maintypes of plastids:

Chloroplasts.

Chromoplasts.

Gerontoplasts.

1. The mitochondrion is a double-membrane-bound organelle found in most eukaryotic organisms. Some cells in some multicellular organisms may, however, lack them. They are in the cytoplasm, not the nucleus. They make most of the cell's supply of adenosine triphosphate (ATP), a molecule that cells use as a source of energy. Their main job is to convert energy.2. The plastid is a major double-membrane organelle found in the cells of plants, algae, and some other eukaryotic organisms. Plastids are responsible for manufacturing and storing of food. These often contain pigments that are used in photosynthesis and different types of pigments that can change the colour of the cell. 3. The Golgi apparatus also called the Golgi complex, is found in plant and animal cells. The Golgi apparatus receives proteins and lipids (fats) from the rough endoplasmic reticulum. It modifies some of them and sorts, concentrates and packs them into sealed droplets called vesicles.4. Vacuoles are storage bubbles found in cells. They are found in both animal and plant cells but are much larger in plant cells. Vacuoles might store food or any variety of nutrients a cell might need to survive. They can even store waste products so the rest of the cell is protected from contamination.5. The endoplasmic reticulum is a type of organelle found in eukaryotic cells that forms an interconnected network of flattened, membrane-enclosed sacs or tube-like structures known as cisternae. There are two regions of the ER that differ in both structure and function. One region is called rough ER because it has ribosomes attached to the cytoplasmic side of the membrane. The endoplasmic reticulum (ER) is the largest membrane-delineated intracellular compartment within eukaryotic cells.
