types of asexual reproduction

types of asexual reproduction

The Penicillium reproduce, asexually by conidia. The conidiophores arise from aerial hypha as well as from those that are submerged in the substratum. These are simple with generally smooth walls or sometimes, the walls may become roughened due to granulations, echinulations or even warts. The conidiophores may either be single or may form clusters or fascicles. These may be of one of the following two distinct types.

Pesticides are chemicals, which are used to kill unwanted insects, fungus, rodents etc. They areRodenticides (Kill rodents and some other mammals)Fungicides -- . Pesticides ->-' Herbicides (Kill plants)(Kill fungi ana plantbacterial pathogen) -IInsecticides (Kill insects)important component for high input farming and, therefore, there is a strong tendency at presentto resort to the use of pesticides.The term pesticide is a broad one. Classification of pesticides is shown below in Table 10.7.PesticidesDefinitionExamples :InsecticidesA substance or mixture of substances usedfor killing unwanted insects.Benzene hexachloride, DDT, parathion,diazinon, metathion, methiocarb, aldrin,p-dichlorobenzene.HerbicidesThe chemicals, which are used inagricultural fields to control or kill theherbs, weeds and bushes.2, 4 - dichlorophenoxy acetic acid,2, 4 - dichlorophenol,sodium trichloroacetateFungicidesFungicides are those chemicals which whenapplied to the plants or to their seeds,inhibit or prevent fungi, parasitic plantscomprising the molds, smuts, mildews,rust, etc.Dithocarbamates, bordeaux mixture.

When light photons fall at the junction, electron-hole pairs are generated. These move in opposite directions due to junction field. These charges accumulate at the two sides of the junction and photo-voltage is developed. It is used in calculators etc.

molar mass of oxygen

Introduction to metric measurement mass: The mass or the weight of the objects is a measure equal to the force exerted by the gravitational force on the same object. There are the measurements like the S.I unit, metric unit and other conventional units of mass measurement. The metric unit is based on the base unit the gram. In this article we will see about the metric unit of the mass measurement.

rounding rules

Notation of Integers:The general form of integers isZ= {……-2,-1, 0, 1, 2…}The Basic operations in math areAdditionSubtractionMultiplicationDivisionThe main rules that are used in the place of basic arithmetic operations:Estimation: Estimation means generally rounding to the nearest value. For Example 99 is rounded to the value 100. Because 99 is very nearer to 100. The values 91,92,93,94 are rounded to the value 90 because these are less than 95. The values 95,96,97,98 and 99 are rounded to the value 100 because it is greater than or equal to 95.
