Read this paragraph from the section "Studying Space Microbes."
A new study of the life forms, or organisms, living on the space station found that there are more types of life living there than there are in the carefully controlled rooms at the Jet Propulsion Laboratory on Earth. JPL is a government-funded space research center. The researchers also detected some tiny types of life on the station, or microbes, that could be harmful to human health.

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.

Answer:
Please find the answers to the following questions below:
Explanation:
1. DNA stands for deoxyribonucleic acid
2. In eukaryotes, DNA is found in the nucleus of the cell while it is found in the cytoplasm of prokaryotic cells.
3. Chromatin is an uncondensed complex of DNA and histone proteins while chromosomes are a condensed form of chromatins. Chromatin can be seen during interphase stage of cell division while chromosomes become visible during prophase stage.
4. Three (3) letters are in the code of DNA. These three letters make up a codon.
5. Adenine - Thymine
Cytosine - Guanine
6. GCATCTACTACCGTAGATGTTACCGAGATTCGAC
7. Proteins are a part of the structural composition of the body
Proteins serve as catalyst for biochemical reactions
Proteins are source of nutrients
8. Amino acids are the monomeric units of proteins. This means that a protein molecule is composed of many amino acid units.
9. DNA is a molecule that stores genetic information in the cell of an organism.
Explain what a karyotype is and
how it can be used to evaluate
the genetic health of an
individual.
Explanation:
Clinical cytogeneticists analyze human karyotypes to detect gross genetic changes—anomalies involving several megabases or more of DNA. Karyotypes can reveal changes in chromosome number associated with aneuploid conditions, such as trisomy 21 (Down syndrome).
Karyotype is a test to identify and evaluate the size, shape, and number of chromosomes in a sample of body cells. Extra or missing chromosomes, or abnormal positions of chromosome pieces, can cause problems with a person's growth, development, and body functions.

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.

→Do EM waves travel faster in denser matter←
good answers only, BAD ANSWERS GET REPORTED
Answer:
No
Explanation:
Electromagnetic waves travel slowest in dense matter such as solids. On the other hand, mechanical waves travel quickly through solids. For example, sound travels fastest through solids. This difference is because EM waves do not rely on the movement of particles to travel. Since they require no medium they can travel the fastest in space or other vacuums.
