What happens when magma cools during the rock cycle? Igneous rock is formed. Metamorphic rock is melted. Sediments form sedimentary rock. Metamorphic rock forms sediments.
Answer: igneous rock is formed
Explanation:
When magma cools down during the rock cycle then igneous rock is formed. Thus, the correct option is A.
What are Igneous rocks?Igneous rock is one of the three main rock types, while the other being sedimentary and metamorphic rocks. Igneous rocks are the rocks formed through the cooling and solidification of magma or lava from volcano. The magma can be derived from partial melts of existing rocks in either a planet's mantle or the crust.
Lava from the volcano cools to form volcanic rock as well as volcanic glass. This magma can also extrude into Earth's atmosphere as part of a violent volcanic explosion. This magma then solidifies in the atmosphere to form volcanic rock called as tephra. In the atmosphere, tephra is more often called as volcanic ash.
Therefore, the correct option is A.

What is the effect of catalase on the decomposition of hydrogen peroxide? A. It decreases the activation energy needed to start the reaction. B. It decreases the total energy released by the reaction. C. It increases the total energy absorbed by the reaction. D. It changes the ratio of the amounts of the two products.
Answer:
A. It decreases the activation energy needed to start the reaction.
Explanation:
Catalase is an enzyme found in the cells of organisms exposed to aerobic conditions. It is an enzyme that catalyses the breakdown or decomposition of hydrogen peroxide in the liver to water (H2O) and oxygen (O2).
Catalase, like every other enzyme, operates by binding to the substrate, which in this case is hydrogen peroxide. Catalase then REDUCES or LOWERS the ACTIVATION ENERGY needed to start the reaction.

An agricultural biologist was evaluating two newly developed varieties of wheat as potential crops. In an experiment, seedlings were germinated on moist paper towels at 20ºC for 48 hours. Oxygen consumption of the two-day-old seedlings was measured at different temperatures. The data are shown in the graph below. In a second experiment, variety A seedlings at both temperatures were treated with a chemical that prevents NADH from being oxidized to NAD+. Predict the most likely effect of the chemical on metabolism and oxygen consumption of the treated seedlings. Explain your prediction.
Answer:
The definition is listed in the clarification segment below, and according to the present circumstances.
Explanation:
It undergoes different morphological as well as biochemical modifications mostly during germination. Product contains nutrients and even some hydrolases such as energy, carbohydrates. Owing to the availability of phytic compounds, the seed coat seems to be very durable in nature. Hydrolytic enzymes launch their function by consuming oxygen throughout order to remove this hard coating. In several other processes, including the electron transport system as well as the Kreb process, oxygen also becomes necessary.
The initial phase of germinating seeds requires anaerobic environments where even the enzymes dehydrogenase can function. The subsequent dehydrogenase enzyme brings the electron throughout the electron transport system from either the base to oxygen. Unless the oxygen frequency is compared with varieties A and B, it can be seen through the analysis that variety B actually absorbed more oxygen. Oxygen intake rates are also depending upon period.The impact of temperature mostly on absorption of oxygen seems to be present. Shift the supply at low temperatures have a low intake of oxygen, while varieties grown over extreme temperatures use much more oxygen. The metabolism of such a seedling is influenced by temperature. Metabolically active young plants display a larger intake of oxygen.why do plants need to resort to natural and artificial reproductive methods to propogate plants

Terms to use in your answer: amino acid, anticodon, codon, gene, messenger RNA, nucleotide, ribosome, RNA, RNA polymerase, transcription, transfer RNA, translation.
The explanation of transcription and translation using the mentioned key words is as follows:
TRANSCRIPTION AND TRANSLATION
Transcription is the process whereby a gene in a DNA template is used to synthesize a messenger RNA (mRNA) molecule in the nucleus of the cell. This process of transcription occurs with the aid of an enzyme called rna polymerase, which adds the nucleotides complementary to the one it reads in the gene to the growing mRNA strand. Translation, on the other hand, is the second process of gene expression involving the synthesis of proteins from the mRNA sequence. This process occurs in the ribosome where a group of three nucleotides in the mRNA called codon is read by another group of complementary nucleotide in the transfer RNA (tRNA) called anticodon. The tRNA then carries amino acids corresponding to what is read in the codon to the growing polypeptide chain.Learn more about transcription and translation at: https://brainly.com/question/23259013?referrer=searchResults

Bromothymol blue (BTB) is a pH indicator that is also used to detect carbon dioxide (CO2). BTB is blue when pH is basic and CO2 is low. BTB is yellow when pH is acidic and CO2 is high. BTB is green when pH is neutral. A group of students are planning to perform an investigation in which they will place either a stalk of the aquatic plant elodea or a snail in a test tube that contains water with a neutral pH of 7 and BTB. The students will also include a test tube that contains elodea and a snail. Observing color change once the tubes have been placed under a growth light for several hours will allow the students to answer which TWO of the following questions?
A. Do both elodea and snails require oxygen to survive?
B. Does elodea produce oxygen during photosynthesis?
C. Do snails respire faster when placed in a tube with elodea?
D. Do snails use the CO2 produced by elodea to produce oxygen?
E. Does photosynthesis performed by elodea remove CO2 from the water?
F. Does cellular respiration occur at a higher rate than photosynthesis in the tube with only elodea?
I need 2 answers! Thanks
Answer:
E. Does photosynthesis performed by elodea remove CO2 from the water? F. Does cellular respiration occur at a higher rate than photosynthesis in the tube with only elodea?Explanation:
The tubes were placed under a growth light and as the elodea is growing, it would need photosynthesis to provide food. The color changes will therefore allow the students to see the effect photosynthesis has on the CO2 in the water by checking to see if the BTB turns blue which would mean that CO2 was removed by photosynthesis.
The students will also be able to see which process occurs faster in the tube with only elodea because the dominant color would show if cellular respiration occurs faster than photosynthesis or if the case is the reverse. For instance, if respiration is occurring faster, there will be more CO2 which would turn the BTB towards yellow, if photosynthesis is faster the BTB will turn towards blue and if the rates are similar, the BTB will remain green.

Cells spend very little of their life performing mitosis. Most of a cell’s life cycle is spent in interphase. Interphase is made up of the first growth phase, the synthesis phase, and the second growth phase. The synthesis phase is characterized by -
The division of cytoplasm
Cell division
Replication of mitochondria and other organelles
DNA replication
Answer:
DNA replication
Explanation:
Synthesis is the stage characterized by DNA replication. It is after the G1 phase
Most of the cell's time is spent in the interphase. The first growth phase comes first, then the synthesis phase, and finally the second growth phase. In the synthesis phase, DNA replication occurs. So the last option is correct.
What is interphase in a cell cycle?
The interphase is the preparatory phase of the cell before going into the division phase (M phase). The first phase is the G1 phase, or first growth phase, in which the cell grows in size. Then the cell enters the synthesis phase, or S phase, where the cell's genetic material, which is DNA, is replicated.
A single DNA molecule duplicates itself, but the two DNA molecules are linked by a single centromere. In synthesis phase the centrosome replicates too, making two centrosomes. Then the cell enters the second growth phase, or G2 phase. Here the cell again grows for the division.
Hence, in the synthesis phase, DNA replication occurs. The last one is correct.
