Que signifie ADN et comment on le prouve?

Answer:

<h3>Qu'est-ce que l'ADN ?</h3>

L'ADN (acide désoxyribonucléique) est un type d'acide nucléique qui se distingue par le stockage de l'information génétique de la grande majorité des êtres vivants. Cette molécule est formée de nucléotides et a généralement la forme d'une double hélice.

Il est nécessaire de prélever des échantillons de certains fluides corporels qui peuvent être du sang, de la salive, des ongles, des cheveux ou du sperme. À l'aide de techniques de laboratoire sophistiquées, l'ADN des échantillons est isolé, puis une cartographie est effectuée, ce qui est fait par des équipements appelés "Séquenceurs d'ADN".

Pour le prouver, normalement le rapport d'un examen ADN apporte quels gènes et chromosomes ont été étudiés et l'analyse du généticien à leur sujet. Les résultats sont présentés dans des rapports simples et clairs. Dans les examens de paternité, le résultat est toujours comparatif.

J'espère t'avoir aidé, bonnes études !

Explain what is ecological conservation and conservation of the environment. What can you do to conserve the environment? Why do
den301095 [7]

Answer:

Conservation ecology is the branch of ecology and evolutionary biology that deals with the preservation and management of biodiversity and natural resources. Its goal is to find ways to conserve species, habitats, landscapes, and ecosystems as quickly, as efficiently, and as economically as possible.

-These are some examples of how we can conserve the environment:

Recycle your rubbish and participate in or help organize recycling campaigns.

Avoid littering and participate in or help organize litter clean-ups (here you can link to a website for volunteering or starting your own beach clean-up).

Use less plastic by, for example, carrying a reusable water bottle, saying no to disposable straws and cutlery, avoiding plastic toys, and bringing your own shopping bags (for further ideas on a plastic-free life take a look here).

Swap toys, movies, and books instead of buying new ones.

Donate, recycle, and repair electronic devices (see how here).

Use less water when brushing teeth, taking a shower, or washing the dishes.

Use less electricity by turning off lights and electronic devices when not in use, using energy-saving light bulbs, and hanging clothes to dry.

Use public transport, share a journey with friends (e.g., car-sharing), cycle, or walk when possible.

Use less paper by not printing unnecessary things and reading e-books.

Turn down the air conditioning when it is hot and use fans if you are still hot-they use much less power.

Turn down the heat when it is cold and use sweaters, blankets, and socks to keep warm.

Do not waste food and try to buy food that is grown locally and in season.

Hope this helps:)

How does gravitational electrical and magnetic forces act on a maglev train
vampirchik [111]
The gravitational force is being felt as the Earth pulls the train downwards using the two forces. The coils that provide the forces releases an electrical current which makes an electromagnetic field. It repels the materials with an equal force that goes up as well.

What are carbon dioxide in cellular respiration reaction. NEED HELP ASAP!!!
marissa [1.9K]

Answer:

Microorganisms such as cyanobacteria can trap the energy in sunlight through the process of photosynthesis and store it in the chemical bonds of carbohydrate molecules. The principal carbohydrate formed in photosynthesis is glucose. Other types of microorganisms such as nonphotosynthetic bacteria, fungi, and protozoa are unable to perform this process. Therefore, these organisms must rely upon preformed carbohydrates in the environment to obtain the energy necessary for their metabolic processes.

Cellular respiration is the process by which microorganisms obtain the energy available in carbohydrates. They take the carbohydrates into their cytoplasm, and through a complex series of metabolic processes, they break down the carbohydrate and release the energy. The energy is generally not needed immediately, so it is used to combine ADP with phosphate ions to form ATP molecules. During the process of cellular respiration, carbon dioxide is given off as a waste product. This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates. Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons. This oxygen gas is identical to the oxygen gas given off in photosynthesis.
