Why do you think the terms "on" and "off" are written under genes ?
Genes are DNA segments that are present on chromosomes and regulate to produce different proteins, so "on" and "off" are written to make the gene ready and not to produce protein.
What is the regulation of genes?Genes produce proteins, this protein has various functions in the cell at a specific time duration in the organism's life, so this process is regulated at several stages so every protein is made in the perfect amount and at the exact time.
The regulatory proteins are responsible for these processes to make genes turn on and off conditions which produce appropriate protein at times when it is needed this decides the cell's condition at various stages.
Therefore, the terms "on" and "off" are written under genes for gene regulation in the cell.

Cuáles son los beneficios y daños que producen las siguientes sustancias. Dióxido de carbono Monóxido de carbono Óxido nítrico Dióxido de azufre Monóxido de hierro
Answer and Explanation:
Dióxido de carbono:
- Beneficio: Gas que se encuentra en la naturaleza y que resulta indispensable para las plantas para llevar a cabo la fotosíntesis. No nocivo en concentraciones entre 300 ppm a 550 ppm.
- Daño: A elevada concentración, cercanas a 30.000 ppm, es considerado contaminante y provoca alteraciones como mareos, dolor de cabeza, somnolencia, problemas para respirar. A concentraciones superiores puede causar asfixia.
Monóxido de Carbono:
- Beneficio: En muy bajas concentraciones puede ser beneficioso para tratar algunas enfermedades vasculares. También puede ser utilizado como marcador o indicador de salud al medir el monóxido de carbono exhalado.
- Daño: Produce intoxicación y causa dolor de cabeza, mareos, debilidad confusión, entre otros. En alta concentración, y sin ser advertido, puede incluso llevar a la muerte. Es un gas altamente inflamable por lo que a parte de las afecciones a la salud por inhalación, también puede provocar explosiones.
Óxido nítrico:
- Beneficios: Posibilita una mayor recepción de nutrientes y oxigeno en músculos, favoreciendo la vasodilatación y la irrigación sanguínea. Regula la presión arterial.
- Daño: En exceso, en una persona que no lo necesite, puede causar daños en los riñones e hígado y puede alterar el pH interno.
Dióxido de Azufre:
- Beneficios: En baja concentración, puede actuar como conservante impidiendo la aparición de bacterias, lo que puede resultar de utilidad en algunos alimentos.
- Daño: En estado gaseoso involucrado en el cambio climático y en la lluvia ácida. Provoca irritación de ojos, irritación de vías respiratorias y de membrana mucosa, y piel. También puede provocar dolores de cabeza, nauseas, y otros malestares. A través de las vías respiratorias, pasa al sistema circulatorio.
Monóxido de hierro:
- Beneficios: Muy utilizado en la industria. Es utilizado en cosmética y como pigmento para distintas utilidades. El oxido de hierro colabora en la limpieza de contaminación ambiental por los gases producidos por vehículos y fábricas.
- Daños: La inhalación crónica de monóxido de hierro puede resultar en siderosis, y puede resultar en cáncer pulmonar.

Beginning with solar energy, detail how the transfer of energy drives weather and climate. Be sure to mention how energy transfer affects wind, rain, temperature, and climate.
Thank u in advance!! ^^
Answer:
Climates and weather activities are driven by solar energy. The option among all the options that are given in the question is the third option. It is a known fact that the surface of the earth is very not even, and this is the reason that the surface of the earth also absorbs solar energy differently.
Explanation:

In double-blind studies neither the test subject or the researcher knows who was given the drug and who was given the control. Why are these studies effective for testing a drug that may elevate mood and relieve feelings of depression?
Answer:
Placebo effect
Explanation:
People tend to think they've been cured by something even if the something isn't effective, and they might even experience minor symptoms of having been effectively treated. If people know that the drug they're being given is the one being tested, they'll be more likely to experience this effect because it's the drug that the researchers think is going to work. Researchers conduct double-blind studies to prevent bias in the researchers and to prevent the placebo effect from interfering with the results from the test subjects.
Answer:
D. The patients and researchers are not given this information so they cannot be influenced in reporting the effectiveness.

Which of the following is the correct order for the nitrogen cycle beginning with nitrogen gas?
a nitrogen gas - nitrate — ammonium - nitrite
b nitrogen gas - nitrite -nitrate - ammonium
C nitrogen gas - ammonium - nitrite - nitrate
d nitrogen gas - ammonium - nitrate - nitrite
The nitrogen cycle which is converted to an intermediate, is generally used by the organism at certain levels, hence option c nitrogen gas, ammonium, nitrite, nitrate is correct.
What is the nitrogen cycle?The nitrogen cycle in the biogeochemical cycle converts nitrogen into various chemical intermediates as it cycles into the air, terrestrial, and marine environments.
The nitrogen conversion processes occur through both biological and physical mechanisms. Fixation, ammonification, the first two steps, nitrification, and denitrification are all important processes in the nitrogen cycle.
The bulk of the Earth's atmosphere contains (78%) majorly composed of atmospheric nitrogen, make the primary source of nitrogen.
Therefore, option c begins with nitrogen gas, ammonium, nitrite, and nitrate in the correct order.
