What combines to form rocksminerals Crystal'sother rocks​

Biology
1 answer:
vampirchik [111]3 years ago
6 0

Answer:

A rock is a collection of minerals. In a cooling lava, mineral crystals do not have time to form and are very small. The chemical composition will be the same as if the magma cooled slowly. Existing rocks may be heated enough so that the molecules are released from their structure and can move around.

How pollution from burning fossil fuels in vehicles can be reduced
Drupady [299]

Explanation:

Incinerators are not helpful in reducing pollution as they produce a lot of ash and smoke so it increases the air pollution by burning of waste.

Solar and wind energy are the clean source of energies replacing the fuels. Catalytic converters reduce the air pollution from the exhaust fumes of vehicles.

What occurs during the tetrad formation?
Elis [28]

Answer:

The tetrad occurs during the first phase of meiosis. It is the foursome of chromatids that forms when replicated homologous chromosomes align. It must be formed for crossing over to occur. It is broken apart when the homologous chromosomes separate in meiosis I.

Pseudomonas syringae strain Lz4W is a Gram-negative, Antarctic soil species that grows at 0ºC. This strain has been used to det
marin [14]

Answer:

A. The RNA polymerase subunits of the P.syringae strain probably have extra flexibility so that they can move more freely in colder temperatures.

Explanation:

Because there is no difference in the amount of the RNA polymerases but rather their activity, the difference lies in their structure and not their sequence. Hence the answer can't be (B) or (D). Adaptations are made to broaden the conditions of survival. Hence E. coli would not limit it's survival by limiting its growth to warmer temperatures. Hence the answer is (A) the RNA polymerase subunits of the P. syringae strain probably have extra flexibility so that they can move more freely in colder temperatures.

Enolase is an enzyme that catalyzes one reaction in glycolysis in all organisms that carry out this process. The amino acid sequ
lorasvet [3.4K]

Answer:

a) The response indicates that a pH below or above this range will most likely cause enolase to denature/change its shape and be less efficient or unable to catalyze the reaction.

b)The response indicates that the appropriate negative control is to measure the reaction rate (at the varying substrate concentrations) without any enzyme present.

c)The response indicated that the enolase has a more stable/functional/correct/normal protein structure at the higher temperature of 55°C than at 37°C because the enzyme is from an organism that is adapted to growth at 55°C.

Explanation:

Enolase catalyzes the conversion of 2-phosphoglycerate to phosphoenolpyruvate during both glycolysis and gluconeogenesis.In bacteria, enolases are highly conserved enzymes and commonly exist as homodimers.

The temperature optimum for enolase catalysis was 80°C, close to the measured thermal stability of the protein which was determined to be 75°C, while the pH optimum for enzyme activity was 6.5. The specific activities of purified enolase determined at 25 and 80°C were 147 and 300 U mg−1 of protein, respectively. Km values for the 2-phosphoglycerate/phosphoenolpyruvate reaction determined at 25 and 80°C were 0.16 and 0.03 mM, respectively. The Km values for Mg2+ binding at these temperatures were 2.5 and 1.9 mM, respectively.

Enolase-1 from Chloroflexus aurantiacus (EnoCa), a thermophilic green non-sulfur bacterium that grows photosynthetically under anaerobic conditions. The biochemical and structural properties of enolase from C. aurantiacus are consistent with this being thermally adapted.
