Answer:

the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.

Explanation:

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar

Question: Using your understanding of the 4 macromolecules explain how Earth’s early atmosphere and the 4 molecules taught could

Zielflug [23.3K]

Answer:

Advanced forms of life existed on earth at least 3.55 billion years ago. In rocks of that age, fossilized imprints have been found of bacteria that look uncannily like cyanobacteria, the most highly evolved photosynthetic organisms present in the world today. Carbon deposits enriched in the lighter carbon-12 isotope over the heavier carbon-13 isotope-a sign of biological carbon assimilation-attest to an even older age. On the other hand, it is believed that our young planet, still in the throes of volcanic eruptions and battered by falling comets and asteroids, remained inhospitable to life for about half a billion years after its birth, together with the rest of the solar system, some 4.55 billion years ago. This leaves a window of perhaps 200-300 million years for the appearance of life on earth.

divine interventionThis duration was once considered too short for the emergence of something as complex as a living cell. Hence suggestions were made that germs of life may have come to earth from outer space with cometary dust or even, as proposed by Francis Crick of DNA double-helix fame, on a spaceship sent out by some distant civilization. No evidence in support of these proposals has yet been obtained. Meanwhile the reason for making them has largely disappeared. It is now generally agreed that if life arose spontaneously by natural processes-a necessary assumption if we wish to remain within the realm of science-it must have arisen fairly quickly, more in a matter of millennia or centuries, perhaps even less, than in millions of years. Even if life came from elsewhere, we would still have to account for its first development. Thus we might as well assume that life started on earth.

How this momentous event happened is still highly conjectural, though no longer purely speculative. The clues come from the earth, from outer space, from laboratory experiments, and, especially, from life itself. The history of life on earth is written in the cells and molecules of existing organisms. Thanks to the advances of cell biology, biochemistry and molecular biology, scientists are becoming increasingly adept at reading the text.

An important rule in this exercise is to reconstruct the earliest events in life's history without assuming they proceeded with the benefit of foresight. Every step must be accounted for in terms of antecedent and concomitant events. Each must stand on its own and cannot be viewed as a preparation for things to come. Any hint of teleology must be avoided.

Why does sexual reproduction result in greater diversity among offspring than asexual reproduction

marusya05 [52]

Bc while asexual reproduction is a copy of your genes and DNA, sexual reproduction involves an infinite amount of combos from your genes and your partner's genes as well.

Animal regeneration can produce whole organism or parts of organism and repair injury.

Clones today are done at genetic level by using molecular biology techniques as compared to old days when only nucleus would be removed from the egg cell and desired nucleus is inserted for cloning.

Explanation:

Regeneration is a process in which whole organism or part of which is produced from pre existing cells or group of cells and tissue. Regeneration helps in maintaining the integrity of morphology and physiology.

In lower animals like hydra and planaria whole organism is generated by existing parts. This process is termed as totipotency.

In higher animals however injury repair by mitosis is an example of regeneration.

Plant structure involved in vegetative propagation are: bulbs, rhizomes and tubers.

Vegetative propagation can be done by grafting, cutting, bulb formation, tuber, layering and tissue culture methods.

Cloning is a process in which a genetical or identical copy of an organism or the cell is made by molecular biology techniques. The use of DNA sequences, molecular scissors, stem cells and plasmid are the latest techniques of cloning.

Cloning is used for treating serious diseases as diabetes and heart injury.

In old days one cell would have its nucleus removed and placed into the egg and eventually organism produced

Advantages of tissue culture:

From a single explants, large number of plants can be made.

Obtaining plants of desired trait from tissue culture is easy in short span.

No seeds are required for the growing of new plants.
