Answer:
A photon of light hits chlorophyll, causing an electron to be energized.
The free electron travels through the electron transport chain, and the energy of the electron is used to pump hydrogen ions into the thylakoid space, transferring the energy into the electrochemical gradient.
Answer:
The correct answer is - phagocytes engulf the pathogens and release several inflammatory mediators.
Explanation:
Phagocytes that are present in the immune system are neutrophils, eosinophils, macrophages and the dendritic cells that perform a multistep process that eliminate the pathogen or toxic substance from the site of injury.
Neutrophils and macrophages are the essential phagocytes that play a major role in healing the wound. Neutrophils are phagocytic cells that reach the site of injury first and ingest the bacteria, cellular debris or dead cells and eliminate from the site. These phagocytes also release some inflammatory mediators to help in the process of inflammation.
Macrophages reach to the site of the wound and play a similar role as the neutrophils as they also remove debris and release the inflammatory mediators however they remain for longer time at the site of injury.
Thus, the correct answer is - phagocytes engulf the pathogens and release several inflammatory mediators.
Answer: Acokanthera schimperi (Arrow Poison Tree) is a species of tree in the family Apocynaceae. It has a self-supporting growth form. It has simple, broad leaves. Arrow Poison Tree is a photoautotroph.
Explanation: The bark, wood and roots of Acokanthera schimperi are used as an important ingredient of arrow poison in Africa. All plant parts contain acovenoside A and ouabaïne, which are cardiotonic glycosides. Its fruit is edible, and is eaten as a famine food. When ripe they are sweet but also slightly bitter. Unripe fruits have caused accidental poisoning as they are highly toxic.[3]
The maned rat spreads the plant's poison on its fur and becomes poisonous.[4]
It is also used in traditional African medicine.[5] In Ethiopia, for example, Acokanthera schimperi leaves have been traditionally used for jaundice.
There seeds are dispersed by,
Other methods of dispersal
Some plants don’t invest much energy in complex mechanisms for dispersal. Bluebells or wild hyacinths (Hyacinthoides non-scripta) are one example of a plant that simply drops its seeds directly to the ground. However, the result is that such plants will tend to spread and colonise new areas very slowly indeed.
