Hope this helped!!!XD
Also, can I get brainliest? I only need 1 more to complete the challenge of 5XD
Answer: A. mechanisms for which activity is primarily triggered and shaped by the incoming stimulus information.
Explanation:
Bottom-up mechanism is a process in which a body perceives an incoming stimulus and certain physiological changes occurs in the body working in the direction of upwards that is the signals are transferred to the brain so that the brain could interpret the stimulus. This mechanism suggests the fact that our perceptual experience is based upon the sensory stimuli.
Insulin and glucagon are the hormones that cause blood glucose (blood sugar) preserved in a narrow range. The pancreas serves as the central part of this process. Secreted by the pancreas are both insulin and glucagon. Determined by the production of insulin and glucagon, people can find out whether someone may have diabetes, <span> hypoglycemia, low blood pressure, etc. Insulin or glucose can be prescribed to victims of those listed issues, it is mostly used to balance out the level of glucagon and insulin to try to stop the problem.</span>
The type of stream valley likely to form in a mountainous area is a V- shaped valley. This is a narrow valley that has a profile giving the impression of the letter V. This kind of valley is characterized by steeply sloping sides. It results from a stream eroding downward, a process referred to as downcutting. V - shaped valleys form in mountains or highland areas where streams are in their youthful stage and are flowing rapidly down steep slopes.
Answer:
Photosynthesis
Explanation:
The leaf (from Latin fŏlĭum, fŏlĭi) is the vegetative and generally flattened organ of vascular plants, specialized mainly to perform photosynthesis. The morphology and anatomy of stems and leaves are closely related and, together, both organs constitute the stem of the plant.
Typical leaves - also called nomophiles - are not the only ones that develop during the life cycle of a plant. From the germination, different types of leaves follow each other - coiled, primordial leaves, prophilic, bracts and antophiles in flowers - with very different forms and functions.
A nomophile usually consists of a flattened sheet, a short stem - the petiole - that joins the sheet to the stem and, at its base, a pair of appendages - the stipules. The presence or absence of these elements and the extreme diversity of forms of each of them has generated a rich vocabulary to categorize the multiplicity of types of leaves presented by vascular plants, whose description is called foliar morphology.
