Placentation refers to the arrangement of OVULES inside the ovary. It is of five basic types:(A) Marginal placentation-The ovary in which the PLACENTA forms a ridge along the VENTRAL suture of the ovary and the ovules develop on two separate rows is known to have marginal placentation. This TYPE of placentation is found in peas.(B) Parietal placentation-When the ovules develop on the inner WALLS of the ovary, the ovary is said to have parietal placentation.C) Axile placentation-In axile placentation, the placenta is axial and ovules are attached to it. Examples include China rose, lemon and tomato.(D) Basal placentation-The ovary in which the placenta develops from its base and a single ovule is found attached to the base is said to have basal placentation. It is found in marigold and sunflower.(E) Free central placentation-In free central placentation, the ovules develop on the central axis while the septa are absent. This type of placentation is found in Dianthus and primrose.solutionAnswered Bytoppr1083 ViewsHow satisfied are you with the answer?This will help us to improve betteranswrGet Instant Solutions, 24x7No Signup requiredgirlMore Questions by difficultyEASYMEDIUMHARD

In physics, a force is any INTERACTION that, when unopposed, will change the motion of an object. ... Force can also be described intuitively as a push or a pull. A force has both magnitude and DIRECTION, MAKING it a vector quantity. It is measured in the SI UNIT of newtons and represented by the symbol F.

The coneflower, daisy and coreopsis are just a few examples of flowers that grow YEAR after year from the same roots and stems. Expect a perennial to spend the first GROWING season establishing itself as a PLANT. Flowers will occur during the second season and, if conditions are RIGHT, every year thereafter.

TYPES When CHOOSING your stamp, you need to consider the type of surface you will be working with. Regular stamp ink won’t be nearly as effective or simply won’t work at all on glass or glossy surfaces, and higher quality, quick drying inks are overkill if used on standard paper or stationery. Most surfaces can be divided into two categories; porous or non-porous. Knowing the differences between these types of surfaces helps in MAKING an informed decision when it comes to choosing the right stamp and ink. POROUS Brown Envelope Sealed with Wax and Halloween Return Address Stamp Impression Dictionary.com defines “porous” as:¹ “permeable to water, air, or other fluids” Simply put, it comes down to whether or not a surface or object has holes. Sponges are an easy example of a porous item. However, an item’s porosity can be determined down to nearly a molecular level. The smaller the holes present, the less water and fluids can pass through, but if air or other gases can pass through, then a surface is still considered porous. Examples of porous surfaces include: Standard paper Cardboard Fabrics   STAMPING POROUS SURFACES Typically, you can use regular stamps and ink on porous surfaces. The construction of these materials allows the ink to be at least partially absorbed and will dry relatively quickly. There are exceptions such as cloth or low porosity surfaces. Fabrics can absorb too well causing bleeding and your stamp won’t leave a crisp impression. Again, this is all dependent on the type of cloth. There are many different kinds of textiles with varying levels of thread count and density. However, you’ll generally want to AVOID using standard stamp ink on fabric. Even if an item is technically porous, its holes may be too small to adequately absorb ink. In these cases, it may be best to treat it as a non-porous surface.   NON-POROUS Stack of Magazines with Glasses Resting on Top Inversely, Dictionary.com defines “nonporous” as:² “not permeable to water, air, or other fluids” This is the fundamental difference between non-porous and porous surfaces. The porosity of non-porous surfaces is non-existent or so low that practically nothing can pass through them. Again, this can be observed down to a molecular level. Companies like Applied Paper Technology are able to test the porosity of different types and brands of paper with special porosity testing machines.³ Examples of non-porous surfaces include: Glossy paper Glass Stainless steel   STAMPING NON-POROUS SURFACES Since standard stamp ink is designed to be partially absorbed by the surface it is applied to, special ink is needed to properly and adequately mark non-porous surfaces. SUPER Marking or quick drying ink is best used for these types of items. Since little to none of the ink is actually absorbed into the surface, it needs to dry quickly in order to prevent smearing. Additionally, since Super Marking ink is designed to dry quickly, it works better on cloth and other fabric items. The faster dry time means that the ink doesn’t have as much time to spread and bleed into the surrounding cloth.   CHOOSING THE RIGHT STAMP & INK Which stamp is right for you? That depends on what you want to accomplish. If you’re making cards or stamping your address on envelopes, regular self-inking, pre-inked, or wood handle stamps with standard ink will work BEAUTIFULLY. In contrast, if you’re looking to stamp your logo on a catalog or mark your child’s clothing, pre-inked or wood handle catalog stamps with Super Marking ink are the best way to go. Due to its composition, Super Marking ink is not intended for self-inking stamps. Simply Stamps is your one-stop-shop for all of your stamping needs. Whether you’re looking for standard stamps or need to quick drying stamps for your business’s catalog, we have the supplies you need to make your mark.

surgical operations or accidents, the patient MAY be given blood from outside to save his life. This is called a blood transfusion. The precautions to be taken in this process are: The donor is asked to complete a questionnaire detailing any HISTORY of infectious diseases and other medical issues before they are allowed to donate blood for transfusion. The donor’s haemoglobin level is checked. Once COLLECTED, the blood is examined and screened for possible infectious AGENTS such as HIV and hepatitis. The blood from the donor is cross-matched with the patient’s blood sample to check it is compatible. Blood group is determined by the antigen profile of an individual's’ red blood cells. The most important antigens in blood typing are the ABO and Rh antigens. Every individual has an ABO blood type (blood group A, B, AB, or O), which means their red blood cells may display antigen A, antigen B, both antigens, or neither antigen.Each person is also either positive or negative for the Rh antigen. Overall, these antigens can combine to GIVE 8 possible blood types..

cale tree cutting can lead to deforestation, a TRANSFORMATION of an area from forest to terrain with little vegetation. PLANTS create oxygen and absorb greenhouse gases. The destruction of trees may, therefore, encourage GLOBAL warming. CHANGING temperatures can alter which organisms can survive in an ecosystem.
