Answer:

E

Explanation:

Red blood cells, most white blood cells, and platelets are produced in the bone marrow, the soft fatty tissue inside bone cavities. Two types of white blood cells, T and B cells (lymphocytes), are also produced in the lymph nodes and spleen, and T cells are produced and mature in the thymus gland.

Answer:

In the human adult, the bone marrow produces all of the red blood cells, 60–70 percent of the white cells (i.e., the granulocytes), and all of the platelets. The lymphatic tissues, particularly the thymus, the spleen, and the lymph nodes, produce the lymphocytes (comprising 20–30 percent of the white cells).

25. A student measures the distance from a bridge
kkurt [141]

Answer:

(4) As time increased, distance remained

the same

Explanation:

The graph shows that the student measures equal distance everyday from the bridge to the rock for 7 days.

Everyday has an equal distance measured by the student all through the week.

Let's say the point on the vertical axis which represents distance measured is about 1.5 meters. It means that, for day 1, he measures 1.5 meters, day 2, he measured 1.5 meters, by day 3 another 1.5 meters. Same he does for 7 days. For the first 3 days, he would have measured 1.5 m × 3 = 4.5 meters.

This means that, as time (days) increased, distance measured each day remains the same.
