Answer:
Sister chromatids found in each of the cells previously originating in meiosis I are separated during meiosis II.
Explanation:
Meiosis is the process of cell division used to obtain sex cells or gametes. Unlike mitosis, the daughter cells obtained in meiosis have half the chromosome charge, i.e. they are haploid.
The result of meiosis I is two haploid daughter cells, in which each chromosome is made up of two sister chromatids, still attached. During meiosis II, whose duration is short, the sister chromatids separate, and each cell will give rise to two haploid daughter cells.
The end result of meiosis I and II is four haploid daughter cells, which become gametes.

Answer:
mineral -
This is any element or inorganic compound. It is a naturally occuring solid chemical compound found in pure form. It is commonly found within rocks.
metal -
an element known for is lustrous, opaque, and malleable properties. Metals are good conductor of heat and electricity.
ore -
This is a natural rock from which minerals, elements or metals can be extracted through mining.
alloy -
An alloy is a group of metals or metals that have one or more other elements. Take for example, red gold is a combination of gold and copper while white gold is a combination of silver and gold.
Answer:
Photosynthetic reaction center differ from the chlorophyll molecules in the antenna complex by the presence and absence of core pigment and accessory pigment.
Explanation:
Photosynthetic reaction center contain core pigment known as chlorophyll A which can aborb wavelength of sunlight not more than 700 nm in case of Photosystem 1 and the core chlorophyll pigment of Photosystem 2 absorb light having wavelength of 680nm or less than that.
Antenna complex or light harvesting complex such as chlorophyll b ,Carotenoid,Xanthophyll absorb light energy from sunlight and transfer that light energy to photosynthetic reaction center by resonance energy transfer so that the photosynthetic reaction center uses the same(light energy) in form of chemical energy to out the further reactions of photosynthesis.
