How are the fluke larvae transferred from the snail (invertebrate host) to the vertebrate host?

Answers

The eggs of the fluke are passed into water supplies from feces and urine of infected people. After hatching the parasite actively swims and invades the body of a snail, usually by penetrating through the snail's foot. The parasite requires the presence of certain species of snails (e.g., Oncomelania, Biomphalaria, Bulinus) to transform (and multiply) itself into an infective stage, called cercaria.

According to cell theory flowers, blood, bacteria and skin all are made up of cells.

What is cell theory?

The cell theory is a scientific theory that was initially developed in the middle of the nineteenth century, which states that all living organisms are composed of cells, that cells are the fundamental structural/organizational unit of all organisms, and that all cells originate from pre-existing cells.

Knowing that all living things are cells helps us comprehend how they are born, grow, and die. That information helps us understand how new life is produced, why creatures take their forms, how cancer spreads, how diseases can be handled, and more. Cells help us grasp life and death: a living creature is alive, while a dead one is dead.

Therefore, flowers, blood, bacteria and skin all are living things made up of cells.

Answers

Answer:B, C and D

Explanation:

A single molecule of some compounds can contain thousands of carbon atoms. Each carbon atom can form single bonds with up to four other carbon atoms. Thus, all of the given statements are true.

What are the properties of carbon atom?

Carbon is found in almost all the biomolecules and majority of compounds present in the atmosphere. All the living things contain carbon in the form of different biomolecules. A single molecule of some compounds can contain up to thousands of carbon atoms including polymers which make up the cell wall and cell membrane.

Each carbon atom can form single bonds with up to four other carbon atoms. This is due to the valency of carbon which is four, thus it can form covalent bonds with other atoms or elements. This property of Carbon is known as tetravalency. Carbon has the ability to form long chains when it gets linked with other carbon atoms.

Each carbon atom can form double bonds with up to two other carbon atoms or more.

Therefore, all these statements are true.
