posledela

Answer:

Option c (No, T cells left from the previous infection can kill any virus.

)

Explanation:

When ever viral infection occur, body's immune system start to fight against it by activating B-cells and T-cells.

B-cells produce antibodies that bind with virus and act as label. This label indicate virus as foreign substance. Hence T-cells recognize it and kill it. Furthermore, B-cells form memory cell that keep the viral memory. if this viral infection occur again in future, T-cell recognize it and eliminate the virus.This mechanism is called immunity.

Explain the mechanisms for movement of materials across cellular membranes anatomy
trapecia [35]
There are 2 types of transport mechanisms that involve the movement of materials across the cellular membrane:

1. Passive Transport Mechanisms which is the movement of materials that does not require energy. Instead the movement relies on the permeability of the cell. Under this are three kinds of passive transport mechanisms:

a. Simple Diffusion: 
- the movement of materials from a region of higher concentration to lower concentration. No external energy is necessary for the movement. The materials supply the energy themselves. 

b. Facilitated Diffusion:
- This differs from simple diffusion because the movement is facilitated by proteins that make up the structure of the membrane. The proteins include channel proteins that allow ions and smaller molecules to cross the membrane. The other protein are the carrier proteins, which bind to materials like sugar molecules and move it across the membrane.  

c. Osmosis:
- This is the diffusion of water across the membrane. Osmosis moves water from regions where there are more water molecules of water per volume to regions where there are less water molecules per volume.  

2. Active transport on the other hand is a movement mechanism that requires energy. It uses the energy to send materials against the direction it is coming from through simple diffusion. This mechanism is used in a way to keep unwanted ions or other materials out of the cell.

Which of the following statements is true about isotopes?
kirill115 [55]
Isotopes are variants of a particular chemical element which differ in neutron number, although all isotopes of a given element have the same number of protons in each atom. The term isotope is formed from the Greek roots isos and topos, meaning "the same place"; thus, the meaning behind the name is that different isotopes of a single element occupy the same position on the periodic table.

Charlie lifts a box with a force of 500 N and sets it on a table top 1.2 m above its starting position. Lauren pushes an identic
astra-53 [7]

Answer:

Explanation:

Workdone is the force applied to move a body in a specified direction.  

  Work done  = Force x distance

For first box;

          Work done  = 500 x 1.2  = 600J

For the second box = 500 x 5  = 2500J

Lauren did more work compared to Charlie because he move the box through a larger height which is the distance in this scenario.
