Answer:
spiders are. generally ectotherms.Their internal temperature depends on external temperature transfer.They are also poikilothermic because the body temperature varies with that of the external environment.,
In animals, individual cells are grouped into tissues. e,g Blood. The tissues gives rise to organs.
A main function of most types of epithelial tissue is covering surfaces.They line major all hollow surfaces, and covering body surfaces.
Resorption id the movement of fluid from the glomerular filtrate back into the blood. Ions, glucose,and other escaped metabolites are returned to the blood stream.
In humans, goosebumps are a vestige of a mammalian adaptation to thermoregulation. This is a thermoregulatory mechanism to regulate the body temperature,Goosebumps emits heat, to turn the moisture from the skin to vapour. This evaporate to release this moisture, which cools the body.
Explanation:
Sporophyte generation - It is found in both seed and seedless plant. Dominant phase of the life cycle of the seedless plants is diploid sporophyte while in seed plant male and female gametes fuses to produces a diploid zygote which develops into a sporophyte.
Pollination - It occurs in seed plants only
Sporophyte contains male and female reproductive structures - It is found in both seed and seedless plant.
Single fertilization - It occurs in both seed and seedless plant
Sperm cells transported by water to egg cells - seedless plant only
I believe it is 13 m towards the origin position, or just 13 m south.
<em>An organ has more kinds of specialized cells. </em>
<u>
A tissue consists of a single (specialized) cell type, whilst an organ consists of multiple tissues.</u>
