Answer:
Eosinophils
Explanation:
If you have severe allergies, your white blood cell differential will show an elevated eosinophils (type of white blood cell) count. These are a type of leukocytes that are produced during an allergic reaction, parasite worm infestations and autoimmune diseases. They are used to fight inflammatory and allergic infections.
Answer:
Explanation:
Parenchyma
1. They have thin cell wall.
2. Their cell wall is made up of cellulose.
3. They are unspecialized tissues.
4. The are found in soft part of the plant.
5. They undergo photosynthesis and can stored the food and also play important role in gaseous exchange.
6. There are spaces between the cells.
Collecchyma.
1. They are thick cell walls.
2. Their cell walls are made up of cellulose and lectin.
3. They are specialized tissues
4. They are found in plants leaves and petioles.
5 The do not undergo photosynthesis but act to give mechanical support to plants.
6. They have little intercellular spaces.
Parenchyma and collecchyma are both tissues found in plants..
Bacteria take on many roles in the environment. They act as decomposers at the end of food chains and food webs. During decomposition, they also liberate advantageous gases and nutrients which are used by other living beings.
Some bacteria also participate in the nitrogen cycle, making fixation of nitrogen, nitrification and denitrification, almost always in mutualist ecological interaction with plants.
Bacteria also live inside us; there are over 500 species of bacteria in the human gut and they are responsible for carbohydrate fermentation and absorption; prevention of the growth of pathogenic microbes in the gut by occupying the space that would otherwise be used by harmful microbes; and they are also involved in immunity, metabolic function and prevention of inflammatory bowel disease.
<span>Excessive proliferation or mass destruction of bacteria can impact entire ecosystems. For example, when a river is polluted by organic material the population of aerobic bacteria increases since the organic material is food for them; the great number of bacteria then exhausts the oxygen dissolved in water and other aerobic beings (like fishes) undergo mass death.

Answer:
In nature, there are a number of useful soil micro organisms which can help plants to absorb nutrients. Their utility can be enhanced with human intervention by selecting efficient organisms, culturing them and adding them to soils directly or through seeds. The cultured micro organisms packed in some carrier material for easy application in the field are called bio-fertilisers. Thus, the critical input in Biofertilisers is the micro organisms.
Answer:
A: DCAB
Explanation:
There are lot of different types of domestic cats nowadays, with the variations coming mostly from mutations and selective breeding. Some cats are very small, some pretty large, some have long fur, some don't have fur (or rather seem like they don't) etc. The Siberian cat weighs 8-17 pounds, British shorthair 7-12 pounds, Turkish van 7-20 pounds, ragdoll 8-20 pounds, with the females being smaller than the males.
