Biology
2 answers:
vlada-n [284]3 years ago
7 0

<u>The best estimated pressure is 110 GPa</u>. Pressures in the lower mantle begin at 24 GPa and reach up to 136 GPa at the border between core and mantle. For the most part it is composed of a single mineral called perovskite. Recent experiments show that this mineral with iron content is very unstable in the lower mantle.

Earth’s layers are determined by their physical properties and chemical composition. In the lesson, you learned about each of Ea
Mkey [24]

Answer:

Generally, the Earth is divided into spheres which include the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air). The earth is divided into three layers based on chemical composition and these are the core, mantle and crust. In addition, the earth is also divided into physical properties which include lithosphere, athenosphere, mesosphere, outer core and inner core. Based on the given details, we can conclude that the atmosphere cannot be part of the lithosphere but instead, it is classified in a separate layer. The lithosphere only consists the outermost, rigid part of the Earth, which are the crust and the mantle. Hope this answer helps

Answer:

The correct answer is D Sister Chromatids may not attach to each other.

Explanation:

Centromeres are the specific point to which the sister Chromatid binds.That means Centromere function to hold the sister Chromatids.

        Now according to the question if mutation causes formation of defective centromere then the normal functioning of that centromere will be hampered.

         As a result the sister chromatid may not attach to each other.

In the mitochondrial electron transport system, hydrogen atoms removed from nadh ultimately end up as part of __________.
Sergio039 [100]

The answer is water. This occurs through the following reaction. During this oxidative reaction of NADH by O2, the energy expended is used to synthesize ATP from ADP and Pi.  Because NADH generated in the cytosol cannot enter the mitochondrion, electrons and protons from NADH are transferred in by an electron shuttle system.
