Biology

The spread of oak blight likely occurs through infected plant material, rainwater, and soil. Foliar hosts may play an important role in the transmission of the infection to bark canker hosts. Moist, cool, windy conditions are thought to spread the pathogen by dispersing spores from the leaves of foliar hosts.

Prokaryotic cells do not have a pre-defined nucleus. The chromosomes in prokaryotes are dispersed in the cytoplasm. In eukaryotes, the chromosomes remain intact inside the nucleus and there is a conspicuous nuclear membrane surrounding the nucleus.

Another difference is that, there is cytoplasmic movement in prokaryotes, whereas there is no cytoplasmic movement in eukaryotes.

Prokaryotic: also no membrane-covered organelles, has circular DNA and bacteria, Eukaryotic: membrane-covered organelles, linear DNA and all other cells. Prokaryotic as a group is the most metabolically diverse. Eukaryotic makes many histones, a type of protein that structurally stabilizes the DNA.

A tricglyceride is a glyceride occurring naturally in animal and vegetable tissues; it consists of three individual fatty acids bound together

A graduated cylinder is a piece of laboratory glassware used to accurately measure out volumes of chemicals for use in reactions. They are generally more accurate and precise for this purpose than beakers or Erlenmeyer flasks, although not as precise as a volumetric flask or volumetric pipette. They come in a variety of sizes for different volumes, typically 10 mL, 25 mL, 50 mL, or 100 mL and up to as large as 1 or 2 liters.

Determine the volume contained in a graduated cylinder by reading the bottom of the meniscus at eye level.

If you do not use instruments or lab apparatuses correctly (or use an apparatus for something it is not intended for) you can very seriously injure yourself!

In addition, if you misuse instruments used for measurements, the results of your experiments will be wrong because you will not have correctly measured the thing you were trying to determine, and so you will draw the wrong conclusion about the result of the experiment.

Nematocysts are on Cnidarians

Spicules are in Poriferae

It is because leaves have chloroplasts, which have a green pigment, which also have chlorophyll inside them. They are used for conducting photosynthesis, which gives the tree glucose, which is its food.

Because no free radicals are involved in the reaction process only carbo cations and Cl- are evolved which are ionic.

An acute disease is which does not last for a longer duration n has no weakness in the body

The word "sori" is the plural form of "sorus". In ferns, a sorus (pl. sori) is a cluster of sporangia on the edge or underside of a fertile frond. In many species, they are protected by an umbrella-like cover called the indusium."

First cells in take carbon dioxide and does photosynthesis, which takes water, sugar, and CO2 and then creates oxygen and a green pigment.

However, plants breed just like animals and thus use up all the O2 they produce (or almost all). They are auto-sufficient.

What is commonly referred to as 'brain freeze' occurs when you ingest something that is very cold too quickly. When the cold touches your soft palate it constricts the blood vessels in the area, and then when they dilate it causes pain behind the eyes or even up into the forehead. Your brain does not actually freeze; you just get a lot of pain for a short period.

H2O + 6CO2+ Light Energy ----> C6H12O6+ 6O2

6 molecules of water + 6 molecules of carbon dioxide --->1 molecule of glucose + 6 molecules of oxygen

The one molecule of sugar C6H12O6 is the glucose molecule

This means that carbon dioxide (6CO2) w/ Water

(6h2o) and light energy creates glucose and carbon dioxide

It is similar to a beaker, except that it gets narrower at the top. It is used to hold liquids and do reactions in it.

It is a device, made with nylon bristles attached to a twisted-wire shaft, used to knock the bottoms out of test tubes.

Fins are used by squids to move at low speeds. Their siphon is used when they need to move quickly.

Light reactions are reactions, which are initiated by light (also photo-induced reactions). Generally, light energy is converted into chemical energy.

Cellulose is a long-chain polymeric polysaccharide carbohydrate, of beta-glucose. It forms the primary structural component of green plants. The primary cell wall of green plants is made primarily of cellulose; the secondary wall contains cellulose with variable amounts of lignin. Lignin and cellulose, considered together, are termed lingo cellulose, which (as wood) is argued to be one of the most common biopolymers on Earth (chrysolaminarin is often argued to be the other). Only one group of animals, the tunicates, has the ability to create and use cellulose. Some acetic acid bacteria are also known to synthesize cellulose.
