Cattle egret follow herds of cattle and feed on both the insects stirred by the movement of the cattle and the biting insects th
kirill115 [55]

Commensalism relationship is shown between cattle egret and cattle.

Usually cattle egrets follow herds of large hoofed mammals such as cattle, buffalo. They eat the insects that have been stirred up by the buffalo as they move. This relationship is commensalism, because the birds benefit but the ungulate is neither harmed nor helped.

The cattle egret and grazing cattle in a close association is a classic example of commensalism. It is a common sight in rural areas where one can see ticks hovering over the cattle. They feed on cattle's blood and hence are harmful to them as they can transmit several diseases. The cattle egret and grazing cattle in a close association is a classic example of commensalism.

The following are the steps for B-cell activation. The steps are in an incorrect order.
Nataly_w [17]

Answer:

4. B cells become activated by interacting with helper T cells.  

1. B cells display antigens in MHC class II receptors on the cell surface.  

2. Antibodies released by plasma cells bind to the antigen so they will be destroyed by other cells of the immune system.

3.B cells rearrange their DNA to create a unique B-cell receptor.  

5. B cells undergo clonal expansion.

6. B cells digest antigens that bind to the antibodies on their surface.

Explanation:

B-cells get activated by interacting with helper T cells when they bind to the antigen to receptors i.e (MHC class II receptors on the cell surface) on the surface of the cell. Series of activities such as release by plasma cells which cause rearrangement of B cells causes the cell to divide and proliferate. The process through which daughter cells arise from a parent cell called clonal expansion.
