what action describes a chemical change?
freezing water, melting ice, lighting a match, or crushing rock.​

Answers

Answer 1

Answer:

Lighting a match.

Explanation:

When the match burns it goes through a chemical change due to the materials such as phosphate, sulfur, etc. The heat then burns the phosphorous on the match's head.

Sorry if it didn't make sense.

Answer 2

Answer:

Lighting a match

Explanation:

Lighting a match and letting is burn is an example of a chemical change because the two reactants (fire and the match) form a new substance. Freezing water, melting ice and crushing a rock are physical changes because they only change in size, shape or form.

Answers

Answer:

One eats during the day and the other eats at night.

Explanation:

Answer:

Well, it really depends on the type of animal (for example water, land). However an adaptation like being able to eat different foods would decrease competition between them as they don't have to hunt the same prey.

List two general differences between inner and outer planets.

Astronomy.

Answers

Answer:

Inner planets are smaller than the outer planets; gas giants have more gravity; Farther apart, inner planets have a solid surface, Inner planets are hotter, inner planets have a shorter period of revolution. Distance from the sun causes these differences.

Explanation:

The four inner planets have slower orbits, slower spin, no rings, and they are made of rock and metal.

The four outer planets have faster orbits and spins, a composition of gases and liquids, numerous moons, and rings.

The outer planets are made of hydrogen and helium, so they are called gas giants.

Inner planets are closer to the sun while outer planets are farther. Also, inner planets don’t have rings but some outer planets do.

Parent strand of DNA is CCTAGCT. What is the complementary strand?

Answers

Answer:

GGATCGA

Explanation:

Adenine goes with thymine and Cytosine e goes with guanine.

Basically A is with T; C is with G

Note that:

C matches with G

T matches with A

In this case, the strand of DNA given is CCTAGCT. The complementary strand would therefore be GGATCGA.

The mitochondria of eukaryotic cells contain two forms of the EF G protein. EF G1mt acts an elongation factor as expected, but EF G2mt acts as a ribosome recycling factor. Individuals with certain single nucleotide polymorphisms (SNPs) in the EF G2mt gene are known to have an increased number of side effects associated with taking statin drugs that treat high cholesterol. The most common side effect is muscle weakness, but they can be as severe as muscle breakdown and liver failure. Propose a mechanism by which SNPs in the EF G2mt gene may lead to these side effects.

Answers

Answer:

The correct answer is - polymorphism mechanism.

Explanation:

Polymorphism mechanism in mitochondrial elongation factor gene EFG2: It involves escalates the atorvastatin toxicity and affects the cell respiratory function. Polymorphisms within the EFG2 factor gene lead to the implication in disease. This gene factor may result in adverse drug reactions such as STATIN, that can leads to side effect to the condition that can affect skeletal muscle severely.

EFG2 plays an essential role which is specific in mitochondrial ribosome recycling. EFG2mt gene is required for cell growth on galactose medium using small interfering RNA splicing of expression in human cell lines.

Such mutation exhibits an atorvastatin-sensitive phenotype and shows less respiratory capacity. this concludes that the first phenotype associated with SNPs in the EFG2mt gene and implicates the human EFG2mt gene as a pharmacogenetic gene for stain toxicity in humans.

why we are saying it as carbaminohemoglobin not carboxyhemoglobin???​

Answers

that carboxyhemoglobin is (protein) the stable complex of carbon monoxide with hemoglobin; it prevents the normal complexing with oxygen and thus leads to anoxia while carbaminohemoglobin is a compound of haemoglobin and carbon dioxide, one of the forms in which carbon dioxide exists in the blood.

At the end of an investigation, a student writes, Seeds at the hottest temperature died. However, at the slightly warm temperatures, seeds grew bigger and faster. Therefore, some heat increases growth, but too much kills the plant. What part of scientific investigation is this?
A. question and experiment
B. Hypothesis and observation
C. evaluation and critique
D. evidence and logical reasoning

Answers

Answer:hypothesis and observation

Explanation:

i did the test

The part namely evidence and logical reasoning is given in the given paragraph. The correct option is D.

What is logical reasoning?

Logical reasoning is a mental activity that seeks to reach a logical conclusion.

The student's assertion is based on observations made during an investigation as well as logical reasoning based on those observations.

The student noticed that seeds exposed to the highest temperatures died, whereas seeds exposed to slightly lower temperatures grew larger and faster.

This evidence was used by the student to logically reason that while some heat can increase growth, too much heat can kill the plant.

As a result, the student's statement represents the conclusion reached based on the evidence gathered and the logical reasoning employed to interpret that evidence.

As a result, evidence and logical reasoning are important components of scientific investigation.

Thus, the correct option is D.
