An unknown material has a mass of 4.5 g and a volume of
6.75 cm3. What is the density

Answers

Answer:

0.67 cm³

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass = 4.5 g

volume = 6.75 cm³

We have

[tex]density = \frac{4.5}{6.75} \\ = 0.6666666...[/tex]

We have the final answer as

0.67 cm³

how are the light reactions and the calvin cycle connected?

Answers

Answer:

The light reactions provide the Calvin cycle with oxygen for carbon fixation, and the Calvin cycle provides the light reactions with sugars to produce ATP. The light reactions provide ATP and NADPH to the carbon fixation step of the Calvin cycle, and the Calvin cycle provides water and electrons to the light reactions.

Explanation:

The energy that drives the Calvin cycle comes from ATP and NADPH produced by the light reactions, that is, the energy capture reactions in the first stage of photosynthesis.

The Calvin cycle is a process that results from photosynthesis made by plants, through which Carbon dioxide is absorbed and transformed into organic material or biomass.

In the light phase, light energy is stored in organic molecules that provide energy to carry out the process (ATP) and have the ability to donate electrons (reducing power) to another molecule such as NADPH.

These molecules formed in the light reactions participate in the reactions that make up this cycle during which carbon dioxide (CO2) taken from the atmosphere is fixed, incorporating it into the body in the form of glucose thanks to the action of the enzyme RuBisCo.

Therefore, we can conclude that the molecules constituted in the light reactions (ATP and NADPH) participate in the reduction of carbon dioxide (CO2) through the series of reactions of the Calvin Cycle.

the mass number for an atom is numerically equal to which quantity

Answers

Answer:

The mass number of an atom is equal to the number of protons plus the number of neutrons that it contains. In other words, the number of neutrons in an atom is its mass number minus its atomic number.

Explanation:

protons

The mass number of an atom is its total number of protons and neutrons. Atoms of different elements usually have different mass numbers , but they can be the same. For example, the mass number of argon atoms and calcium atoms can both be 40.

If a cell has 4 chromosomes at the beginning of meiosis, how many chromosomes will be in each cell at the end of meiosis?

Answers

Answer:2. Mitosis would produce identical daughter cells with the same number as the parent cell. Meiosis would product sex cells with one-half the amount of genetic material as the parent cells.

Explanation:

If a cell has 4 chromosomes at the beginning of meiosis then the daughter cell will have TWO chromosomes at the end of meiosis.

Meiosis is a type of reductional cell division by which a parental cell duplicates its genetic material (DNA) and then divides twice to produce four (4) daughter cells having half of the genetic material.

These successive cell division cycles are known as Meiosis I and Meiosis II.

Meiosis is a sexual mode of reproduction that produces gametes or geminal cells, which fuse during the process of fertilization to form a zygote.

In conclusion, if a cell has 4 chromosomes at the beginning of meiosis then the daughter cell will have TWO chromosomes at the end of meiosis.

in the reaction of aluminum metal and oxygen gas to make aluminum oxide, how many moles of aluminum will react with 0.80 grams o2?

Answers

Explanation:

When 6.38 moles of O2 and 9.15 moles of Al react, the ratio of aluminum to oxygen is 9.15/6.38 = 1.434. This shows that all of the oxygen is consumed before the aluminum and when the reaction ends the reactant aluminum is left. The number of moles of Al2O3 formed is approximately 4.25 moles.

Certainly most of us regard happiness asthe proper end of all earthly enterprise. The will to be happy animates alike the philosopher, theprince and the chimney-sweep. No matter how dull, or how mean, or how wise a man is, he feelsthat happiness is his indisputable right.2 It is curious to observe what different ideals of happiness people cherish, and in what singularplaces they look for this well-spring of their life. Many look for it in the hoarding of riches, somein the pride of power, and others in the achievements of art and literature; a few seek it in theexploration of their own minds, or in the search for knowledge.3 Most people measure their happiness in terms of physical pleasure and material possession.Could they win some visible goal which they have set on the horizon, how happy they would be!Lacking this gift or that circumstance, they would be miserable. If happiness is to be someasured, I who cannot hear or see have every reason to sit in a corner with folded hands andweep. If I am happy in spite of my deprivations, if my happiness is so deep that it is a faith, sothoughtful that it becomes a philosophy of life,if, in short, I am an optimist, my testimony tothe creed of optimism is worth hearing....4 Once I knew the depth where no hope was, and darkness lay on the face of all things. Thenlove came and set my soul free. Once I knew only darkness and stillness. Now I know hope andjoy. Once I fretted and beat myself against the wall that shut me in. Now I rejoice in theconsciousness that I can think, act and attain heaven. My life was without past or future; death,the pessimist would say, a consummation devoutly to be wished. But a little word from thefingers of another fell into my hand that clutched at emptiness, and my heart leaped to therapture of living. Night fled before the day of thought, and love and joy and hope came up in apassion of obedience to knowledge. Can anyone who has escaped such captivity, who has feltthe thrill and glory of freedom, be a pessimist?5 My early experience was thus a leap from bad to good. If I tried, I could not check themomentum of my first leap out of the dark; to move breast forward is a habit learned suddenlyat that first moment of release and rush into the light. With the first word I used intelligently, Ilearned to live, to think, to hope. Darkness cannot shut me in again. I have had a glimpse of theshore, and can now live by the hope of reaching it.6 So my optimism is no mild and unreasoning satisfaction. A poet once said I must be happybecause I did not see the bare, cold present, but lived in a beautiful dream. I do live in abeautiful dream; but that dream is the actual, the present,not cold, but warm; not bare, butfurnished with a thousand blessings.
