List and explain the function of 7 major organelles of animal cell .The answer:
The Rock Cycle is a group of changes. Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. ... Or, igneous rock can form above ground, where the magma cools quickly.
The Tectonic Cycle is the process in which tectonic plates are created at rift zones where molten material pushes plates apart and destroyed at subduction zones as oceanic plates descend into the mantle. But only oceanic plates are subducted.
The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. Ice and snow can sublimate directly into water vapor. ... Most precipitation falls back into the oceans or onto land, where, due to gravity, the precipitation flows over the ground as surface runoff.
The carbon cycle is the process in which carbon travels from the atmosphere into organisms and the Earth and then back into the atmosphere. Plants take carbon dioxide from the air and use it to make food. Animals then eat the food and carbon is stored in their bodies or released as CO2 through respiration
The nitrogen cycle involves three major steps: nitrogen fixation, nitrification, and denitrification. It is a cycle within the biosphere which involves the atmosphere, hydrosphere, and lithosphere. ... Instead, they depend on a process known as nitrogen fixation.
Phosphorus moves in a cycle through rocks, water, soil and sediments and organisms. Over time, rain and weathering cause rocks to release phosphate ions and other minerals. This inorganic phosphate is then distributed in soils and water. Plants take up inorganic phosphate from the soil.
Answer:
B
Explanation:
I think the answer is B. Heat poses a huge threat to climate change. Hope it helps!
Answer:
(A) two
Explanation:
A heterodimeric protein consists of two polypeptides (a polypeptide is a chain of amino acids) that differ in amino acid composition, number or order in the chain sequence. Each polypeptide makes a different subunit of the protein.
One gene encodes one polypeptide, so if the protein has two different polypeptides, two genes are required to form this protein.
Possible Genotypes: WW, Ww, ww
Possible Phenotypes: Has widow's peak or doesn't have widow's peak.
