The best protection from Haemophilus influenza that causes infant meningitis is administration of conjugate vaccines.
Vaccines are injections administered into body to provide protection. They are based on the principle that prior introduction to weakened or killed from a microorganisms produced natural immunity against it which is remembered by the body by memory cells.
The conjugate vaccines are combination of weak and strong antigens which results in stronger immunity against weak antigens. The conjugate vaccine of Haemophilus influenza comprises polysaccharide of the microorganism. Strong antigen are also known as carrier proteins and in this case are either of tetanus, diptheria toxoid or its mutant toxin of diptheria.

Since the transferrence is interrelated in a system called the food chain where the nutrients from plants is carried off by the first-consumers and second-consumers and so on untill the decomposers take the energy from the withered living organism and back into the system, it is mostly the transferrence of energy.
This flow of energy is present in its development and thus, the food composed by the photosynthetic autotrophs then is changed and took in by herbivores and then when omnivores or carnivores eat them it is translated into another form where it is stored in the cells used in many bodily activities.
Answer:
Field research and laboratory research are different from each other on various accounts. In a lab, the study is not on such a broader level as that on a field.
Some of the tools in a lab and a field study will be same because such tools cannot be changed. For example, for amplification of genes, PCR will be used whether a field research is being made or a lab research.
On the other hand, some of the tools will be different. For example, to study field plants we'll use quadrants for counting but in a lab, as a lesser number of plants are understudy so we won't need a quadrant.
I can't see the well but chemical changes happen when a substance combines with another to form a new substance. These processes are called chemical reactions and are not reversible except if you do more chemical reactions... So the well that is changing it's state of matter should be the one undergoing a chemical change. For, example boiling or freezing
Answer:
Sea anemones are marine predatory animals. They are like a terrestrial flowering plant due to their colorful appearance. They are coming under the phylum cnidaria.
Sea anemones are found in different forms called a polyp. It has a columnar trunk, on the top of the trunk an oral disc and centrally placed mouth. The mouth is surrounded by tentacles.
Sea anemones have a gastrovascular cavity that serves as stomach. This cavity has one opening both meant for mouth and anus.
Sea anemones are capable of changing their shape and lives on the mud, holding it by pedal disc.
Polychaetes are segmented worms. Each segment of the body bears parapodia. It helps them in locomotion. There are different types of polychaetes, tube-dwelling polychaetes are one of them.
Tube - dwelling polychaetes make tubes to protect their soft bodies.
They don't have parapodia but some special anterior structures for feeding. The tubes are made from calcareous materials.
