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
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.

Okazaki fragments are formed on which strand?
Answer:
The leading strand is continuously synthesized and is elongated during this process to expose the template that is used for the lagging strand (Okazaki fragments). During the process of DNA replication, DNA and RNA primers are removed from the lagging strand of DNA to allow Okazaki fragments to bind to.

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

List two general differences between inner and outer planets.
Astronomy.
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.

between them?
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.

Somatic stem cells can be turned into as many types of cells as embryonic stem cells
True
Fasle
The given statement Somatic stem cells can be turned into as many types of cells as embryonic stem cells is false.
Somatic stem cells are also known as adult stem cells and are found in various tissues throughout the body. While they have the ability to differentiate into multiple types of cells within their tissue of origin, they are generally limited in their ability to differentiate into other types of cells.
Embryonic stem cells, on the other hand, have the ability to differentiate into all cell types of the body, which is why they are considered pluripotent. They are derived from embryos during the early stages of development and are therefore not found in adult tissues.
In summary, while somatic stem cells have the ability to differentiate into multiple cell types within their tissue of origin, they are not as versatile as embryonic stem cells and cannot differentiate into as many types of cells.
