<em>The continental crust is up to 70 km thick.</em>
<u>Explanation</u>:
Upto 40% of the earth is made up of continental crust. <em>Sedimentary, igneous and metamorphic ricks </em>make up the continental crust. It makes up the upper layer of <em>continents and shallow seabed</em> areas near the shores.
<em>Continental crust</em> is thicker than oceanic crust with a thickness ranging from <em>25 km to 70km continental crust</em> makes up 70% of earth’s volume and is usually located above sea level with a few exceptions like the <em>Zealand continental crust</em> region which is largely under water.
Intermediate magma is also known as andesitic magmas and these are created when an oceanic plate subducts beneath a continental plate. The magma is generated in the wedge of mantle rock beneath the crust. The Cascade Mountain Range is formed due to the subduction of the Juan de Fuca Plate beneath the North American Plate.
<span>The answer is a), all red, as no white alleles are present in the parents, [ and hence cannot be passed on to the offspring. Showing work- Let R represent the dominant (red) allele: RR(male) x RR(female) ----> All RR offspring.</span>
Answer:
Photosystem I (PS-I )and photosystem II (PS-II ) are two multi-protein complexes. These complexes contain the pigments used to absorb, harvest and catalyze the photons and light energy in the photosynthetic reactions. The main purpose of photosynthesis reactions to produce high chemical energy compounds.
Photosystem I and II are different from each other because of their absorbing wavelength of light. PS-I absorbs the longer wavelength of light than PS-II.
PS-I plays the major role in the production of high energy carriers ATP and NADPH using light energy (700 nm).
PS-II plays its function in the hydrolysis of water and ATP synthesis using light energy (680 nm).
