<h2>Anterior-posterior orientation</h2>
Explanation:
Flatworms have an anterior-posterior orientation and as a result more coordinated and deliberate movement is established
- Flatworms also called Platyhelminthes are a phylum of relatively simple soft-bodied invertebrate animals
- They are the largest phylum of acoelomates and are found in marine,freshwater and even in some damp terrestrial environments
- Movement in some flatworms is controlled by longitudinal,circular and oblique layers of muscle
- Flatworms anterior end helps in moving towards their food while the posterior end ensures that these organisms walk away from irritants
They occurred in industrialized areas.
Explanation:
possible benefits of genetic engineering include:
More nutritious food
Tastier food
Disease- and drought-resistant plants that require fewer environmental resources (such as water and fertilizer)
Less use of pesticides
Increased supply of food with reduced cost and longer shelf life
Faster growing plants and animals
Food with more desirable traits, such as potatoes that produce less of a cancer-causing substance when fried
Medicinal foods that could be used as vaccines or other medicines
Answer:
The answer is spongy mesophyll.
Explanation:
Between the upper and lower epidermis of a leave, you can find the so called mesophyll tissue which is rich in chloroplasts. There are two types of mesophyll tissue: the palisade and the spongy mesophyll. Whereas the cells of the palisade mesophyll are tightly packed, the cells of the spongy mesophyll are loosely packed.
The amygdala is thought to control defensive behavior via outputs from the central nucleus of the amygdala
What does the Amygdala do?
It is crucial in processing and regulating emotional reactions. Especially important in strong emotional reactions such as fear and anger
What does the amygdala control?
The amygdala is commonly thought to form the core of a neural system for processing fearful and threatening stimuli , including detection of threat and activation of appropriate fear-related behaviors in response to threatening or dangerous stimuli.
Central nucleus of Amygdala :
The central nucleus of the amygdala (CeA) has been traditionally viewed in fear conditioning to serve as an output neural center that transfers conditioned information formed in the basolateral amygdala to brain structures that generate emotional responses.
What does the central nucleus consist?
The central nucleus of the amygdala (CeA) is primarily composed of GABAergic interneurons which are finely controlled through glutamatergic neurotransmission and signaling. The CeA can be divided into the medial (CeM) and lateral (CeL) divisions
