For photosynthesis to occur, plants need sunlight, water, carbon dioxide and chlorophyll. Through the process of photosynthesis plants convert light energy into chemical energy. They use this energy to make food which they store as sugars.
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

Answer:
Bacteria
Virus
Parasite
Fungi
Explanation:
A Bacteria is a single-celled biotic pathogen that is infectious. Bacteria are prokaryotes(single celled) and also form part of the disease causing organisms .
A Virus is an abiotic pathogen that is infectious.
A Parasite is a biotic pathogen that lives off its host. It sometimes uses structures such as hooks to obtain nutrient material from its host.
A Fungi is a biotic multi-celled pathogen that causes infections like ringworm.
Answer:b. Facilitated transport
Explanation:in the usual activities of the cell,it's cell membrane is responsible for the movement of substance in and out of the cell.
Such substances include nutrients,water, oxygen etc.
The plasma membrane select the substances that it allows into the cell thus it is said to be selectively permeable.
The plasma membrane of the cell has a phospholipid bilayer made up of cholesterol, proteins and glycoproteins.
The proteins on the membrane are useful for facilitated diffusion.
In this diffusion process,the proteins helps to carry large molecules across the cell membrane.such molecules includes glucose,amino acids etc.
In the process energy is not expended so it is a type of passive transport.
