Answer: Lipid refers to any class of organic compounds that are considered fatty acids. This also includes their derivatives that are soluble in organic solvents, like many natural oils, waxes phospholipids and steroids.
All lipids have similar properties because their molecules are made of the same elements with similar chemical structure that only varies slightly.
Foods like meat, poultry, seafood, beans, peas and eggs are all sources of proteins, while good that contains saturated fat like palm oil, coconut oil, milk, cheese and coffee creamers and butter contain lipids, that may help in storing energy.

Can humans affect the carrying capacity of an ecosystem? Explain your answer
Answer:
Carrying capacity is never static. ... More rapid changes in carrying capacity may be caused by disturbances of the habitat occurring because of a fire or windstorm, or because of a human influence such as timber harvesting, pollution, or the introduction of a non-native competitor, predator, or disease.

The atmosphere is full of nitrogen gas (N2). But plants cannot use nitrogen in this form. Summarize the roles of bacteria in making nitrogen available to plants and in returning nitrogen to the atmosphere.
Answer:
Prokaryotes play several roles in the nitrogen cycle. Nitrogen-fixing bacteria in the soil and within the root nodules of some plants convert nitrogen gas in the atmosphere to ammonia. Nitrifying bacteria convert ammonia to nitrites or nitrates.... Denitrifying bacteria converts nitrates back to nitrogen gas.

What sort of fossils would be expected to be found in Antarctica from about the time of Pangaea (250 MYA)?
Answer:
Lystrosaurus as known as or translates to 'shovel reptile'.
Lystrosaurus is the only fossils of this creature have only been found in anatartica, India and south Africa.
Explanation:
Antarctica was once part of the supercontinent of Pangaea, which existed between 300 million and 200 million years ago.
What is the evidence of glaciation?During this time, Antarctica was located near the South Pole and covered in forests and swamps. Fossils of ancient plants and animals that lived during this time period would be expected to be found in Antarctica.
In particular, fossils of the Glossopteris plant, which was a dominant flora during the Permian period (299 million to 251 million years ago), are commonly found in Antarctica. Other fossils that have been found in Antarctica from this time period include those of primitive reptiles, amphibians, and some species of marine life.
In addition to fossils, evidence of glaciation is also found in Antarctica from the Permian period. This includes glacial deposits and striations on rocks, indicating that the climate in Antarctica was once much different than it is today. These fossils and geological features provide important insights into the evolution of life and climate on Earth.

If a DNA strand has a nucleotide sequence of CATGAGTTA, what will the mRNA strand be after transcription?
Answer:
leave the nucleus, goe to the cytoplasm,bind to a ribosome to be read
If a DNA strand has a nucleotide sequence of CATGAGTTA, the nucleotide sequence of the mRNA after transcription will be GUACUCAAU.
TRANSCRIPTION:Transcription is the process by which mRNA molecule is synthesized from a DNA template. In the transcription process, the complementary strand of the DNA is synthesized as the mRNA strand. This means that uracil will be synthesized from adenine and cytosine from guanine and vice versa. Therefore, if a DNA strand has a nucleotide sequence of CATGAGTTA, the nucleotide sequence of the mRNA after transcription will be GUACUCAAU.Learn more about transcription at: https://brainly.com/question/15175461?referrer=searchResults
Que neurotransmisor afecta directamente al musculo esquelético: * Acetilcolina Triptófano Adrenalina Serotonina Endorfina
Answer:
Acetilcolina
Explanation:
La acetilcolina es un neurotransmisor excitatorio producido por neuronas del sistema nervioso periférico, es decir, células nerviosas que conectan el sistema nervioso central (SNC) con los diferentes órganos. La unión de acetilcolina a receptores específicos localizados en células del músculo esquelético conocidos como 'receptores nicotínicos' desencadena la contracción del músculo. Los receptores nicotínicos pertenecen a una superfamilia de proteínas de canales iónicos activados a través de la unión a acetilcolina, lo cual desencadena la despolarización de células musculares esqueléticas. Por otra, parte, la acetilcolina también posee un rol inhibitorio en células musculares cardíacas, donde su unión a receptores especifícos llamados 'receptores muscarínicos' disminuye la frecuencia cardíaca.
