BEES Bees are flying insects closely related to wasps and ants. There are nearly 20,000 known species of bee, in nine recognized families, though many are undescribed and the actual number is probably higher. They are found on every continent except Antarctica, in every habitat on the planet that contains insect-pollinated flowering plants. Bees are adapted for feeding on nectar and pollen, the former primarily as an energy source, and the latter primarily for protein and other nutrients. Most pollen is used as food for larvae. Bees have a long proboscis (a complex "tongue") that enables them to obtain the nectar from flowers. They have antennae almost universally made up of 13 segments in males and 12 in females, as is typical for the superfamily. Bees all have two pairs of wings, the hind pair being
★ The most common food allergies are - milk allergy( not to confuse with lactose intolerance) - egg allergy - nut allergy - wheat allergy Symptoms ★ Vomiting and/or stomach cramps. ★ hives ★ shortness of breath ★ wheezing ★ repetitive cough ★ tight, hoarse throat, trouble swallowing ★ weak pulse Seasonal allergies ★Spring allergies - the biggest spring allergy trigger is pollen - pollen can travel for miles, spreading a path of misery for allergy sufferers along the way ★ Some of the biggest allergy offenders: - Trees: Alder, Ash, Aspen, Beech, Cedar - Grasses and weeds: Bermuda, Saltgrass, June, Redtop. ★ Symptoms - sniffling - sneezing - itching - rubbing your eyes ★ Summer allergies - are a lot of like spring allergies - even have the same allergy offenders ★ Slightly different symptoms, adding - runny nose - watering eyes
For example when two people are talking privately and then the one interrupts them and asks: "What?", "When?", "Who?","Why?". If its done once, nobody cares but when someone all the time and everywhere needs to know what others are talking about well it's kind of annoying. And then there are these kind of people who smoothly move from one group of people to another group of people and collect any kind of information like bees collect pollen so afterwards they could tell everything they heard to their friends and to add some spice to the whole story they supplement some tiny details which they made up in their heads. In Estonia we have this saying: "In the one edge of a village you farted but in the other edge of village people tell that you pooped yourself." I'm not saying that I never want to know what do other people talk about or I never talk my friends what I have heard
· Recruited - to enlist (a person) for service in one of the armed forces · Tension - the act of stretching or the state or degree of being stretched, also mental or emotional strain; stress. · Traumatise- to subject or be sujected to mental trauma. · Withdrawn- not wanting to communicate with other people. · Allocated - to set apart for a particular purpose · Alter - to change; become different · Hey fever - an allergy caused by pollen or dust in which the mucous membranes of the eyes and nose are inflamed, causing running at the nose and watery eyes. · Aspect - a particular part or feature of something. · complication - something that introduces, usually unexpectedly, some difficulty, problem, change. · Data- individual facts, statistics, or items of information. · Image - an optical appearance of an object. · Obsession- an idea or thought that continually preoccupies or intrudes on
The weather is a national obsession in Britain, perhaps because it is so changeable. It's the national talking point, and most people watch at least one daily bulletin. It can be mortifying for a weather man or woman who has predicted rain for the morning to wake up to brilliant sunshine. These days, a weather forecaster’s job is even more complicated because they are relied upon to predict other environmental conditions. For example, in the summer the weather forecast has to include the pollen count for hayfever sufferers. Some also include reports on ultraviolet radiation intensity to help people avoid sunburn. The job of a weather forecaster is certainly far more complicated than just pointing at a map and describing weather conditions. It's a job for professionals who can cope with stressful and demanding conditions.
9. Describe the first stage of germination. The first stage of germination the primary root or radicle emerges. The stem pushes its way upward until it appears above the surface of the soil. At the same time the root system grows downward and begins to spread through the soil. The seedling depends on the foodstore until the frist leaves are produced and photosynthesis is started. 10. What happens in the process of pollination? In the process of pollination the pollen is carried by the wind or insects from the stames to the stigma of the carpel. It germinates on the stigma and grows down the style into the ovary, where fertilization takes place. 11. Name the most important stages in the life cycle of a plant. The most important stages in the life circle of a plant are: 1. Germination 5. The pollination and fertilization 2. The begin of photosynthesis 6
pollution. CAUSES There are many different chemical substances that contribute to air pollution. These chemicals come from a variety of sources. Among the many types of air pollutants are nitrogen oxides, carbon monoxides, and organic compounds that can evaporate and enter the atmosphere. Air pollutants have sources that are both natural and human. Now, humans contribute substantially more to the air pollution problem. Forest fires, volcanic eruptions, wind erosion, pollen dispersal, evaporation of organic compounds, and natural radioactivity are all among the natural causes of air pollution. Usually, natural air pollution does not occur in abundance in particular locations. The pollution is spread around throughout the world, and as a result, poses little threat to the health of people and ecosystems. Though some pollution comes from these natural sources, most pollution is the result of human activity

The most sensitive organism in an valid acute aquatic toxicity test was Daphnia pulex with an EC50 (48 h) of 5.8 mg/l. For the derivation of the PNECaqua an assessment factor of 1000 is applied on this value resulting in a PNECaqua of 5.8 g/l.n. (EC50 - half maximal effective concentration; PNEC - Predicted No Effect Concentration) Terrestrial Effects Nematodes in peat were killed by application of formalin (37 % formaldehyde solution) at 179 ml/m³ (Lockhart 1972). Pollen grains of Lilium longiflorum which had been sown in a straight line on a culture medium were exposed separately to various concentrations of injurious gases. A 5 h exposure to formaldehyde at 0.44 mg/m³ (0.37 ppm) resulted in a significant reduction in pollen- tube length, whereas a 1 or 2 h exposure was innocuous. When the formaldehyde concentration was increased to 2.88 mg/m³ (2.4 ppm), a 1 h exposure caused a decrease in tube length. Conclusion
the sun's azimuth. This property has been shown to increase light interception and possibly photosynthesis. The sunflower head is not a single flower (as the name implies) but is made up of 1,000 to 2,000 individual flowers joined at a common receptacle. The flowers around the circumference are ligulate ray flowers without stamens or pistils; the remaining flowers are perfect flowers (with stamens and pistils). Anthesis (pollen shedding) begins at the periphery and proceeds to the center of the head. Since many sunflower varieties have a degree of self-incompatibility, pollen movement between plants by insects is important, and bee colonies have generally increased yields. In temperate regions, sunflower requires approximately 11 days from planting to emergence, 33 days from emergence to head visible, 27 days from head visible to first anther, 8 days from first to last anther, and 30 days from last anther to maturity

diktüosoomidega rakkudest. Rakud lagunevad pärast tolmuterade teket, nende kestad lahustuvad ning tsütoplasma satub tolmukapesasse, kus seda kasutatakse tolmutera kestade ülesehitamisel. Mõnedes sugukondades tarvitatakse tolmuterade kasvuks ka vahekihti talletatud ühendeid. Sel juhul võib vanades tolmukapeades vahekiht olla hävinud. Tolmupesades paikneb õietolm, mis koosneb tolmuteradest (pollen). Tolmutera on homoloogne sõnajalgtaimede isasgametofüüdiga. Tolmuterade suurus on keskmiselt 15-50 µm, kuju võib olla kerajas, ovaalne, piklik või kuupjas. Tolmuterade arv sõltub liigist ja tolmlemisviisist - eriti ohtralt tekib tolmuteri tuultolmlejatel taimedel.
