Answer:
This is an example of scientific investigation and all the elements that compose it.
Explanation:
Sarah is doing a scientific investigation regarding the nail polishes she uses. We can see this, because Sarah is using the elements that make up this type of investigation to reach a conclusion about the enamels. These elements are:
Independent variable: Element that influences the appearance of a controlled and evaluable result, such as the enamel that Sarah will use on her nails.
Dependent variable: Element that is influenced by the dependent variable and promotes the visualization of a result, such as the length of time that the enamels can remain on the nail without chipping.
Experimental group: Element that allows the study of the interaction of these variables and the result developed through it, such as Sarah's enamel marks.
Control group: Element where only the independent variable is applied. As the action of the dependent variable does not exist, the observed result is the same that would be perceived if the study was not taking place, such as the day when Sarah did not paint her nails.
Constant: Elements that are exactly the same throughout the experiment, such as the person who conducted it, the time the study will be carried out, the nail care routine and the lower and upper layers of the enamels used.

acetyl group to be used for biosynthesis are transfered across the mitochondrial membrane in what form
Answer:
Acetyl coenzyme A
Explanation:
Acetyl coenzyme A (Acetyl CoA) is an important molecule that is involved in several biochemical reactions in organisms. It plays important functions in lipid metabolism, protein metabolism and carbohydrate metabolism. The major role of acetyl CoA is to transport acetyl group to Krebs cycle for energy production through oxidation.
Acetyl CoA is usually synthesized in the mitochondria through a series of biochemical reactions. In order to deliver acetyl group to the citric acid cycle, it can be synthesized through the oxidative decarboxylation of pyruvate from the glycolytic pathway and also by the breakdown of specific amino acids. After acetyl CoA is synthesized it is transported to the cytosol from the inner mitochondrial membrane.

Epigenetics is most concerned withA)changes in a person's genotyperesulting from environmental influences.B)the expression of a particular gene as influenced by external inputs.C)environmental influences on gene expression over experiential influences.D)the heritability of genotypes that have been altered over multiple generations.
Answer: Option C.
inputs.C)environmental influences on gene expression over experiential influences
Explanation:
Epigenetics is is a field of science that entails the study of heritable changes which is caused by Gene expression modifications without our any form of DNA alterations or changes. It is as a result of environmental influences on gene Expression because of heritable phenotypic changes.
example of an epigenetic change is DNA methylation which is the addition of a methyl group or to a segment of the DNA molecule which prevent the expression of some genes.

3. Which angle is congruent to.<CBA? A.<BCD. B.<CDA. C.<ABC. D.<BAD
Answer:
i think its a TwT
i might be wrong but i tried ;(
The angle that is congruent to <CBA is the angle formed by <CDA, therefore, the second option is correct.
When we study angles and shapes, we are studying Geometry. In Geometry, two different angles are congruent with one another, when one shares certain aspects with the angle it is being compared to. These aspects are:
Shape SizeWhen both of these are equal for the two angles, we can say that those angles are congruent.
For this question, we can look for the angle that most perfectly resembles the <CBA angle. Symmetry is often a hint that can help us find the congruent angle, as it is for this question.
We can see that the shape in the image is symmetrical on its top and bottom halves, and when we look at the bottom half we see that angle <CDA has the same shape and size as angle <CBA.
Meanwhile, the angles <BCD and <BAD do not resemble <CBA in size or shape, so options 1 and 4 are incorrect. Option 3 shows the angle <ABC, this angle is the same as <CBA becuase it is made from the same points (A, B, and C). Since they are the same angle, we do not have two angles to compare, therefore option 3 is incorrect.
Angle <CDA is congruent to angle <CBA because it has the same shape and size.

A chloroplast has stopped producing atp and NADPH
The question is incomplete, so the complete question is as follows:
A chloroplast has stopped producing ATP and NADPH. Which of the following is most likely causing this?
a.The chloroplast has used up its supply of chlorophyll molecules.
b.Electrons have stopped moving through the electron transport chain.
c.The sun has risen and the chloroplast now can make more chlorophyll.
Answer:
b.Electrons have stopped moving through the electron transport chain.
Explanation:
ATP and NADPH are produced in the light dependent reaction stage of the photosynthesis that occurs within chloroplast grana.
ATP and NADPH are produced due to the movement of electron and proton (H+) in the electron transport chain, so if the movement of electrons will stopped in the electron transport chain, the formation of ATP and NADPH will also get stop.
Hence, the correct answer is "b".

Does the point at which our Sun rises change?
Answer:
Hay que saber que el Sol sale por el Este tal y cómo se dice siempre, pero tan solo lo hace dos veces al año. Esto se debe a que la inclinación de la Tierra y sus movimientos de rotación y traslación hacen que los puntos cardinales por donde sale el Sol no estén siempre en el mismo sitio.
Explanation:D
Answer:
Actually, the Sun only rises due east and sets due west on 2 days of the year -- the spring and fall equinoxes! On other days, the Sun rises either north or south of "due east" and sets north or south of "due west." Each day the rising and setting points change slightly.

In which isotope is the strong nuclear force not strong enough to balance electrostatic forces between protons? Carbon-13 hydrogen-2 neon-21 uranium-238
Answer:
The correct answer is "uranium-238".
Explanation:
Uranium-238, is the most abundant isotope of the element uranium. Uranium-238 has not enough nuclear force to balance electrostatic forces between protons, and as a result, it is a radioactive isotope and its losing energy because of the spontaneous breakdown of its atomic nucleus. Uranium-238 has a half-life of 4.5 billion years and is used as fuel in nuclear reactors as well as for dating purposes.
Write a short note on evolution and how new species broaden the scope of classification.
Answer:
A new specie formed as a result of evolution.
Explanation:
Evolution refers to the change in the characteristics of an organism with the passage of time. in the beginning there is only one single plant and animal specie but with passage of million of years changes occurs in the structure and genotype of the organism and as a result, a new specie was formed. So after millions of years, thousands of new species formed and there is a need for their classification in order to make their study easier. So we can say that evolution broaden the scope of classification.
