Answer: Clearly his SYMPATHETIC nervous system has been activated.
Explanation:
The effects of the sympathetic nervous system dominate in times of EMERGENCY or STRESS. And its effects include:
- dilation of pupils to help Gabe see sharply as he investigate
- inhibition of saliva secretion as his mouth turns dry
- acceleration of heartbeat due to fear
- stimulation of sweat glands to produce sweat.
All these show clearly that Gabe's SYMPATHETIC nervous system has been activated.
<span>The female frog's reproductive system is consist of a pair of ovaries and a pair of oviducts. The ovaries are attached to the kidneys. The kidneys carry countless ova which are released to outside through the oviducts. </span><span>In the breeding season, the male and the female frogs enter into a temporary union called amplexus. The male holds the female, presses her trunk and thereby forces the female to release the eggs, the male frog then releases the sperms immediately to bring about exterior fertilization.</span>
Answer:
True
Explanation:
<em>Aristotle initially thought that life arose spontaneously and he backed this up by showing that a lump of meat left uncovered in a glass jar spontaneously produced maggots.</em>
The spontaneous generation theory was later disproved by another scientist, Francesco Redi. He showed that a covered jar containing a lump of meat will not spontaneously produce maggots unless flies are allowed to perch and lay their eggs on the meat. The eggs of the flies give rise to the maggots and not the meat.
<u>It thus showed that new life does not arise spontaneously but rather through development and reproduction.</u>
Populations of organisms that have sigmoid growth curves
limited by the carrying capacity are called K-selected.
Species are divided into two selected species, R-selected
species and K-selected species. K-selected
species are <span>also called K-strategist. These are the species whose populations vary at or near the <span>carrying capacity <span>(K) of the </span></span>environment<span> in which they live.</span></span>
