One of the most unusual aspects of virus particles is the absence of all organelles and other smaller structures. Whereas cells

have many kinds of organelles, viruses consist of only two parts: a nucleic acid core made of DNA or RNA, and a tough, potective protein shell. Which name is given to this tough shell made of protein?

Answer:

Caspid

Explanation:

It is the protein shell which contains the nucleic acid. The shell is comprised of the proteins that are organized in subunits called Capsomers.

Functions of caspid:

1) It gives the nucleic acid protection from enzymes which can digest it

2) There are special sites on its surface that help it to attach to a host cell

3) Contains proteins that help the virion to enter the host cell membrane

4) Sometimes under favourable conditions,viral RNA with some other proteins can assemble the caspid to become infectious virus.

The diagram shows a normal red blood cell and a shrunken red blood cell, both of which are in salt water.
bixtya [17]

Answer: Water moved from inside the red blood cell into the salt water.

This is because of the osmotic difference between the salt solution and the red blood cell. This means that there is difference in the solute (salt) concentration inside the red blood cell and the salt solution.

Explanation: The salt concentration in the solution is higher than the salt concentration inside the red blood cell, that is, the red blood cell has more water concentration that the salt solution, therefore there will be movement of water from the inside of the red blood cell into the salt solution thereby causing the red blood cell to reduce in size. The movement of water from the red blood cell into the salt solution is to create a balance between the water concentration in the two environments, hence the movement of water from an area of high water concentration to an area of low solvent concentration across the selectively permeable membrane of the red blood cell.

Which describes bedrock? consists of solid rock lies directly above the soil layer does not contain weathered rock forms from de
san4es73 [151]

Answer:

consists of solid rock

Explanation:

Bed rock are solid rock material usually below the soil surface.

They are found at the ocean floor under sediment and other solid materials. Saprolite are bed rocks that have been weathered they are found above the bed rock overlaining it,

saprolite have different composition because it has gone through chemical weathering.

Above saprolite are soil and other loosed particle.

when the depth and structure of a bed rock is determined it help tell about the history of a place.
