Answer:

It will become less negative

Explanation:

When a train moves in a direction with decreasing velocity , then it is for sure than acceleration is also decreasing. With stowaways in between before 1 KM of completion of the journey will bring the vehicle in a situation where it will have negative acceleration. Now it is given that force remains same , then with constant mass it is the acceleration which has to increase in order to justify the equation

F = m*a

Since the acceleration was already negative, an increase in acceleration will make it less negative

I believe it is either B or A, personally i'm leaning towards B, but at the same time, i don't think that we would be obtaining materials via pollination, so it then causes A to make more sense.

Which structures are found on sponges?
PSYCHO15rus [73]

Answer:

The special cells of the sponge include those that filter sea water; cells that are phagocytic (that engulf and digest food particles); those that form the external 'skin', breathing pores and tubes through which water enters and leaves the body; and those that secrete the mineral and organic skeletons, called spicules and fibres, respectively. Sponges are also unique because nearly all their cells can change function as required (totipotency).
