mitochondria- where respiration occurs

cell wall- gives the cell structure and prevents it from bursting

chloroplast- contain chlorophyll which stores energy from the sun for photosynthesis

cytoplasm- where chemical reactions occur

cell membrane- controls what comes in and out of the cell.

mitochondria: where respiration occurs

cell wall: gives the cell structure and prevents it from bursting

chloroplast: contain chlorophyll which stores energy from the sun for photosynthesis

cytoplasm: where chemical reactions occur

cell membrane: controls what comes in and out of the cell.

Answer:

Photosynthesis

Explanation:

The green structures in the cell are chloroplasts. They are green because they contain the green pigment chlorophyll. Chlorophyll traps light energy and uses it to produce sugar molecules as food for the cell.

Answer:

Two electrons are added to one sublevel at a time (Hund's Principle)

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.

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.

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.

Answer:

Explanation:

The field of forensic science is important to the criminal justice system. Forensic personnel must pay close attention to detail during the collection, preservation, and analysis of physical evidence. If evidence is mishandled, manipulated, or misinterpreted it can potentially destroy a case and/or the lives of all individuals involved

Answer:

Explanation:

In 1904, Scotland Yard officials introduced fingerprint matching to US law enforcement officials at the World’s Fair. The fact that forensic science was not born from the scientific community meant that forensic scientists were not always bound to the quest for knowledge, but instead for the purpose of solving crimes. This difference led to misaligned incentives. Expert witnesses were often paid per conviction in many states.

In the late 1980s, DNA evidence, which was born in the scientific community, has helped identify the guilty and exonerate the innocent. Many other forensic techniques, such as hair microscopy, ballistics analysis, and arson investigations, have not been subjected to the rigorous scientific evaluation that DNA analysis has. Other techniques, such as blood typing, have been properly validated.

These invalidated techniques have led to the Innocence Project, which holds that forensic science techniques should be shown to be valid and reliable through research and assessment of validity and reliability, and subject to accreditation and certification to assure quality. States are eligible to receive grant money if they do so. This change has resulted in the growth of many organizations, such as the ASCLD/LAB, that accredit forensic scientists.

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:

Explanation:

Answer:

The following statements are true:

The microbe must be present in individuals suffering from the disease and absent from healthy individuals.

If organisms from the pure culture are injected into a healthy experimental animal, the disease symptoms should appear.

The microbe must be isolated and grown in pure culture.

Note: The question is incomplete. The complete question is given below:

Evaluate these statements about Koch's postulates, which are used to establish a causative link between a specific microbe and a specific disease. Which of them are true? Select all that apply.

The microbe must be present in individuals suffering from the disease and absent from healthy individuals.

The microbe does not have to be isolated from the experimental animal as long as the disease is present.

If organisms from the pure culture are injected into a healthy experimental animal, the disease symptoms should appear.

The microbe must be isolated and grown in pure culture.

Explanation:

Robert Koch, a German Physician, in 1884 postulated the following four criteria in order to establish a causative relationship between a microbe and a disease;

From the above, the following out of the statements are true:

The microbe must be present in individuals suffering from the disease and absent from healthy individuals.

If organisms from the pure culture are injected into a healthy experimental animal, the disease symptoms should appear.

The microbe must be isolated and grown in pure culture.

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.

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.

Answer:

Gravitropism (also known as geotropism) is a coordinated process of differential growth by a plant or fungus in response to gravity pulling on it. Gravity can be either "artificial gravity" or natural gravity. It is a general feature of all higher and many lower plants as well as other organisms.

Explanation:

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.
