Kyle wants to get rid of beetles that are in his garden, he notices in areas that in areas that have a certain type of fertilizer in the ground there are more beetles. Choose the best way Kyle can form hypothesis that could help him form an experiment to rid the beetles from his garden?
Answer: Is the fertilizer supporting the growth of beetles?
Explanation:
Here, Kyle wants to get rid of beetles in his garden but he observes that in an area where there is fertilizer there are more beetles. Thus, Kyle can frame the hypothesis that, "Is the fertilizer supporting the growth of beetles?". This hypothesis is forming the basis of experimental trials that can be done on beetles who were exposed to fertilizer and those who were not in laboratory conditions to check whether fertilizer is effective in supporting the growth of beetles. If the fertilizer is useful in supporting the growth then it should not be used in the garden.

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".

Why the characteristics of life are not always perfect guidelines for classifying living things
Answer:
Due to change in environment or evolution.
Explanation:
The characteristics of life are not always perfect guidelines used for classification of living things because these characteristics of life are different for every organism due to change in environment or due to evolution occurs with the passage of time. So for that reason we classify organisms on the basis of common ancestor and similarities in the structure not on the characteristics of life.
Lily visits her family doctor because she experiences an upset stomach after drinking milk. The doctor tells her that this symptom is caused by a lack of the enzyme lactase. Lactase breaks down lactose, the sugar in milk which is made of several parts. What does lactose break down into?

Which one by itself does not possess the ability to synthesize its own proteins?
Please choose the correct answer from the following choices, and then select the submit answer button.
a virus
a human cell, a virus, and a bacterial cell
a viral particle and a bacterial cell
a human cell
a bacterial cell
Answer:
A virus
Explanation:
A virus requires a host cell to implant proteins into so that the host cell can create new virus cells. The virus essentially hijacks the cell.
All other listed cells can create new copies of their own proteins.
Cheers.
A virus does not possess the tendency to synthesize their own proteins.
• Viruses are not animals, plants, or bacteria, however, they are the quintessential parasites of the living kingdoms.
• Viruses are not living organisms as in the absence of a host cell, they cannot perform their life-sustaining activities of reproduce.
• They cannot produce their own proteins, as they are devoid of ribosomes and must utilize the ribosomes of their host cells to convert the viral mRNA into the viral proteins.
Thus, the correct answer is a virus.

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.

Which statement best supports the RNA world hypothesis? a. DNA molecules are a precursor to self-replicating RNA molecules, which are used to build proteins. b. Early RNA molecules were able to self-replicate, which helps to explain why all organisms share the same genetic code C. Simpler self-replicating organic molecules preceded RNA and contain genetic information. d. The absence of oxygen in Earth's early atmosphere allowed for proteins to catalyze the production of new RNA molecules.
Answer:
b. Early RNA molecules were able to self-replicate, which helps to explain why all organisms share the same genetic code
Explanation:
The RNA world hypothesis is an evolutionary theory that indicates the RNA-living forms were produced first before the appearance of DNA and proteins. This hypothesis is supported by the fact that RNA is capable of reproducing on its own (like DNA), and also is able to catalyze chemical reactions (like protein enzymes). The RNA world hypothesis states that this RNA world was then followed by the evolution of ribonucleoproteins.

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.
