Answer:
b.Lymphatic capillaries are dead-end tubes.
d.Lymphatic capillaries are highly permeable.
Explanation:
Lymphatic capillaries transport lymph that flows with little pressure, these capillaries are made of endothelium, <em>are blind-ended (closed at one end) and are more permeable than the blood ones because they serve to drain extracellular fluids.</em>
Blood capillaries, on the other hand, transport blood, that contrary to lymph, flows with more pressure, their walls are also made of endothelium but they are less permeable and conform a circuit, meaning they have no dead ends.

X is equal to 3.3 cm. You can find this by looking at the rate in volume of oxygen collected in 20 mins and the rate of photosynthesis; each value is multiplied by three to get the answer. Therefore, 1.1 x 3 = 3.3, which is your answer
Answer:
a. polarized
Explanation:
The whole living cell and in particular the nerve cells show electric potential difference between the inner and outer faces of their cell membrane.
The resting potential of a cell refers to the difference in electrical potential that the inner and outer faces in the membrane of a neuron that is not transmitting nerve impulses. The resting potential value is around -70mV (milliVolts). The negative sign indicates that the interior of the cell is negative relative to the exterior.
The existence of the resting potential is mainly due to the difference in concentration of sodium (Na +) and potassium (K +) ions inside and outside the cell. This difference is maintained by a mechanism of active ion pumping through cell membranes, in which sodium is forced out of the cell and potassium in.
At rest, the alternation between passive and active ion transport occurs. There is passive input of sodium (Na +) ions, which are subsequently actively expelled, while potassium (K +) ions enter actively. Then K + passes passively from the cell, making the external medium positive relative to the internal medium. With this, the cell becomes polarized.

Answer : Organisms are classified as insects on the basis of their external structures of body.
Insects are the most diversified group of organisms that belong to the phylum Arthropoda.
Their body is primarily divided into three distinct regions that are head, thorax, and abdomen.
They have three pairs of legs (that is why also called hexapods) and two pairs of wings, present in the thorax region.
They possess exoskeleton (external protective covering) that is made up of chitin.
