Answer:
b. Space for complex organ systems
Explanation:
Coelom can be defined as a fluid-filled body cavity with mesoderm lining, one of the germ leaflets. In triblastic animals, there may or may not be coelom. Those who have the cavity have the advantage of using this cavity to store complex internal organs (viscera). When there is no coelom, animals are said to be aceloma, like the flat-body worms - the flatworms.
This cavity is formed during embryonic development and is related to several important functions, such as excreta elimination, temporary gamete deposition, distribution of substances throughout the body, accommodation of internal organs and, in some animals, it also functions as a support.
Answer:
Chlorophyll molecules donate electrons to an electron acceptor in the reaction center.
Explanation:
Light reaction of photosynthesis takes place in the reaction centre. Light reaction may comprises of several proteins such as pheophytin, chlorophyll and quinones which act as light absorbing molecules.
The light reaction is the core of photosynthesis that produces ATP and NADPH to carry out the dark reaction for the production of high energy carbon molecules. During light reaction light photons are captured by photosystems such as photosystem I and II of chlorophyll in green plants. This photon cause the excitation of electron that flows through the electron transport chain from higher potential to lower potential and energy released by it is utilized for creating the gradient potential of H+ ions across the membrane. This gradient potential difference of H+ ions is used for the production of ATP through ATP synthase complex.
So chlorophyll molecules donate electrons to electron acceptors through the excitation of electrons from light photons in the reaction center.
The question is incomplete as it does not have the options which are:
a. the STM recency effect.
b. delayed response coding.
c. the phonological loop.
d. the visuospatial sketch pad.
Answer:
The visuospatial sketch pad.
Explanation:
Working memory is a part of short term memory which is related to the recall and use of the information in the middle of another activity.
visuospatial sketch pad was proposed by Graham Hitch and Alan Baddeley in 1974 and considered the pad as a component of Working memory.
The sketchpad is held the information which is collected during the initial processing and is later saved as long term memory. The pad collects the information related to calculation, physical environment, visualization and many other activities which are later recalled.
Thus, the selected option is the correct answer.
