The substrate of the citric acid cycle which can block respiration when it is present in excess is MALONATE. Malonate inhibits respiration by competing with succinate dehydrogenase for its acitve site. Malonate binds to the active site without reacting, thus competing with succinate. This disrupts the cellular respiration in the cell.

Answer:
Bearded dragons are endothermic, like all reptiles.
Explanation:
Endothermic animals cannot generate their own body heat, they rely on outside temperatures.
Answer:
3. Separation of sister chromatids
Explanation:
Before entering mitosis or meiosis, DNA contained in a cell duplicates and and each chromosome will have two sister chromatids.
- In mitosis the sister chromatids separate to produce two daughter cells that have the same information as the original cell before the DNA duplicated.
- On the other hand, meiosis consists of two cell divisions. During meiosis I, homologous chromosomes separate, producing two daughter cells that have half the information the original cell had, but each chromosome still has two sister chromatids. During meiosis II, the sister chromatids separate, and each daughter cell produces two more daughter cells, that now have a single homologous chromosome of the pair, and which has a single chromatid.
1-A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. ... A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter.
2-Part of Hall of Planet Earth. There are three kinds of rock: igneous, sedimentary, and metamorphic.
3-Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet. When lava comes out of a volcano and solidifies into extrusive igneous rock, also called volcanic, the rock cools very quickly.
4-Igneous rocks are formed from lava or magma. Magma is molten rock that is underground and lava is molten rock that erupts out on the surface. The two main types of igneous rocks are plutonic rocks and volcanic rocks. Plutonic rocks are formed when magma cools and solidifies underground.
