Answer:
The correct Hint is D) Stepwise
Explanation:
Scientific inquiry usually involves a process through which scientists try to resolve tough problems.
Many people have proposed various steps to the methodology of scientific inquiry. There is one that has 3 steps, one that has 5 steps, and another that has 7 steps.
The 7 steps of scientific inquiry are given below:
Defining the Question. Stating the Research. Postulating the Hypothesis. Carrying our the Experiment. Making Observations. Reaching Results/Conclusion.Communicate. Present/share your results. Replicate.Cheers

Explanation:
Sweet yellow tomatoes with a pear shape bring a high price per basket to growers. Pear shape, yellow color, and terminal flower position are recessive traits produced by alleles, f, r, and t, respectively.
The dominant phenotypes for each trait – full shape, red color, and axial flower position – are the product of dominant alleles F, R, and T. A farmer has two pure-breeding tomato lines. One is full, yellow, terminal and the other is pear, red, axial. Design a breeding experiment (crosses) that will produce a line with tomato that is pure-breeding for pear shape, yellow color, and axial flower position.
Answer and Explanation: The farmer has a pure-breeding line of tomato means the farmer has a tomato with genotype FFrrtt while the other line of tomato has genotype ffRRTT.
The cross between these lines gives a F1 generation of heterozygous full, red and axial or FfRrTt.
With an individual of F1 crosses with another individual of F1, the Punnet Square will be:
FfRrTt x FfRrTt
1) Dividing each characteristics, for simplicity:
F f
F FF Ff
f Ff ff
R r
R RR Rr
r Rr rr
T t
T TT Tt
t Tt tt
Analysing Punnett squares, we notice the line wanted (ffrrTT) will be produced, when an individual of F1 generation cross with another individual with the same generation.

Drag each tile to the correct location. Not all labels will be used. Identify the phases in the life cycle of small and big stars. supernova: In this stage, the star collapses and produces elements heavier than iron. planetary nebula: In this stage, the star emits strong energy pulses that push away the outer layers creating a cloud of ionized gas around the core. neutron star: In this stage, the star has reduced to an extremely dense core. white dwarf: In this stage, the star has reduced to a dense core.
Answer:
large= supergiant, supernova, then a neutron star
small= giant, planetary nebula, white dwarf
Explanation:
star life cycle changes by these phases
why it is important to reduce friction in moveable joints
Answer:
Smooth cartilage prevents friction as the bones move against one another. in freely moveable joints, the entire joint is enclosed inside a membrane filled with lubricating synovial fluid, which helps to provide extra cushioning against impact.

Which two characteristics do polar and dry climates have in common?
high altitude and very cold winters
very cold winters and contrasting seasons
contrasting seasons and very little precipitation
very little precipitation and few, specialized plants
Answer:
D. very little precipitation and few, specialized plants
Explanation:
its the answer on edge
The two characteristics which polar and dry climates have in common include very little precipitation and few specialized plants. Thus, the correct option is D.
What are Polar and Dry climates?A polar climate is a place where the climate generally has a temperature below the freezing, icy, and it is covered in snow. These areas do not get enough amount of direct heat and sunlight from the sun. Polar climates are located at the North Pole of the Arctic, and at the South Pole on the continent of Antarctica.
The dry climate are found in deserts which are very dry and the temperature of these areas are very high.
Both of these climates show some common characteristics such as very little precipitation and few specialized plants which can survive in these conditions.
Therefore, the correct option is D.

How does the formation of NAD+ differ between aerobic and anaerobic respiration?
A. NAD+ is formed in aerobic respiration by a fermentation process and formed in anaerobic respiration by oxidation of NADH.
B. NAD+ is formed by a fermentation process in anaerobic respiration by the conversion of pyruvate into lactate and by simple oxidation of NADH in aerobic respiration.
C. Under aerobic conditions, the electron acceptor is a molecule other than oxygen for NAD+ production, whereas under anaerobic conditions the electron acceptor is oxygen.
D. NAD+ is formed by the breakdown of pyruvate to form oxaloacetate in anaerobic respiration whereas in aerobic respiration it is formed by the breakdown of pyruvate into lactic acid or alcohol.
Answer:
B. NAD+ is formed by a fermentation process in anaerobic respiration by the conversion of pyruvate into lactate and by simple oxidation of NADH in aerobic respiration.
Explanation:
Nicotinamide adenine dinucleotide (NAD) is an important coenzyme that may exist in two different forms: oxidized (NAD+) and reduced (NADH). The fermentation is an anaerobic oxidation-reduction reaction where pyruvate and NADH are reactants, while lactate and NAD+ are products generated by the oxidation of NADH to NAD+ and pyruvate to lactate, respectively. On the other hand, during aerobic respiration, NADH generated by glycolysis is oxidized to form NAD+ by the donation of its electrons to reduce pyruvate to lactate. Subsequently, NAD+ is reused in glycolysis (again) in order to generate more molecules of ATP.

Activator or repressor proteins which bind DNA to regulate the transcription of genes do so mainly by: A. Covalent interactions between the protein and specific bases in the major groove of DNA B. Covalent interactions of Zn2 atoms with the phosphodiester backbone C. Non-covalent interactions between the protein and specific bases in the major groove of DNA D. Covalent interactions with nearby nucleosomes E. Answers B and D are correct
Answer:
C. Non-covalent interactions between the protein and specific bases in the major groove of DNA
Explanation:
Activator or repressor proteins are proteins with specific DNA-binding domains that have affinity by one or two DNA strands. In general, these proteins interact with the major groove of the B-DNA structure since this structure exposes more functional groups for binding. Non-covalent interactions are a type of interaction that does not involve the sharing of electrons. The interaction between proteins and DNA is due to the combination of different non-covalent interactions, which can be classified into four major types: van der Waals, hydrophobic, hydrogen and ionic interactions.

When an enemy cell is present, a(n) __________ secretes perforins, which bore a hole in the enemy cell membrane.
a. interleukin
b. antibody
c. interferon
d. natural killer cell
e. opsonization
The correct answers is D. Natural killer cell
Explanation:
Natural killer cells are a type of cell in the immune system. These differ from other cells because these are innate, this means they attack all enemy cells or pathogens and are not specific. Also, they are the first general immune defense.
Moreover, the role of these cells to attack any enemy cell including cancer cells is possible due to specific chemicals or substances these cells release. One of these is perforins, which are mainly released by natural killer cells and destroy these by creating lesions in the cell membrane. According to this, the correct answer is D.
