Answer:

Osmosis - water

Ions - diffusion

Large proteins - endocytosis

Explanation:

Ions and small molecules can cross the cell membrane by simple diffusion, where they move from a high concentration to a low concentration, down a concentration gradient.

Osmosis is the process whereby water travels across a semi-permeable membrane from a high concentration to a low concentration.

Larger cargo can cross the membrane through a process called endocytosis, where the membrane engulfs the particles and brings them inside the cell, encased in a vesicle.

What is mineral ?what are its type​
Andre45 [30]

Answer:

In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form

Explanation:

Silicate Minerals. The first classification of minerals is silicate minerals.  

Native Element Minerals. Native elements refer to minerals that only contain the atoms of one type of element.  

Carbonate Minerals.  

Halide Minerals.  

Oxide Minerals.

Mineral nutrients for the human body include: iron, calcium, copper, sulfur, phosphorus, magnesium and many others. An archaic use of the word "mineral" comes from the Linnaean taxonomy in which all things can be assigned to the animal, vegetable, and mineral kingdoms.

Why can a lytic virus remain in a particular host cell only for a limited time?
AlexFokin [52]

Answer:

Because lytic virus reproduces its phages immediately leading to bursting of the host cell for the new phages to leave.

Explanation:

Viruses employ two major cycles to reproduce themselves namely: lytic and lysogenic cycles. Lytic cycle involves the entrance of the viral cell into its host, using its host's replicational abilities to reproduce and bursting of the cell.

The lytic cycle is carried out by strains of virus called VIRULENT STRAINS. They use the host cell to produce many virions and destroy the cell by lysis in order to leave the host cell. This accounts for the reason they DO NOT STAY LONG IN THEIR HOST CELL.
