Many commercial greenhouses use heaters that burn gas or oil because?

Answers

Answer 1

It promotes the movement of air as heat circulates and rises, helping to reduce excess humidity that could harm crops. This efficient system can not only reduce fuel costs by up to 10%, but it warms the medium and root zone before rising to heat the crops and the air above, creating ideal growing conditions.

The heating of a greenhouse is traditionally done by using a central gas boiler which heats water that is distributed into the greenhouse. ... These hot air heaters run on either natural gas, petroleum and diesel. This direct combustion generates the by-product carbon dioxide, which can be advantageous for plant growth.

Which of the following changes are linked to an increase in ocean water temperature?
Answer A: An increase in metabolism in marine species and a decrease in dissolved oxygen in ocean water

Answer B: A decrease in metabolism in marine species and a decrease in dissolved oxygen in ocean water

Answer C: An increase in metabolism in marine species and an increase in dissolved oxygen in ocean water

Answer D: A decrease in metabolism in marine species and an increase in dissolved oxygen in ocean water

Answers

The changes that are linked to an increase in ocean water temperature are an increase in metabolism and a decrease in dissolved oxygen in ocean water.

What do you mean by Dissolve oxygen?

Dissolve oxygen may be defined as a relative measure of the amount of oxygen that is dissolved in a given medium.

It is universally accepted that a lack of oxygen leads to a rise in temperature. The process of metabolism internally requires energy but on completion of it, the temperature may get slightly increased in the surroundings.

Therefore, the changes that are linked to an increase in ocean water temperature are an increase in metabolism and a decrease in dissolved oxygen in ocean water. So, the correct option is A.

¿Cuál de los siguientes enunciados NO forma parte de la teoría celular propuesta por Schleiden y Schwann, y con aportes de Virchow? * E) Toda célula deriva de otra preexistente D) Todos los seres vivos están formados por células. C) La célula es la unidad de evolución de los seres vivos. A) La célula es la unidad de estructura de los seres vivos. B) La célula es la unidad funcional de los seres vivos.

Answers

Answer:

C) La célula es la unidad de evolución de los seres vivos.

Explanation:

La teoría celular fue formulada por Schleiden y Schwann en 1837 a partir de observaciones propias y de información citológica relacionada con la estructura y la función de las células obtenida muchos años anteriores a ellos, especialmente a partir de los aportes de 1-Anton Van Leewenhoek, quien identificó microrganismos vivos mediante sus observaciones con un microscopio, y 2-Robert Hooke, quien observó celdas (de allí el nombre de células) también bajo el microscopio. Schleiden y Schwann postularon que la célula debería ser la unidad estructural y funcional en los seres vivos, la cual debería ser capaz de mantener de modo independiente el estado vital. Posteriormente, en 1855, Virchow aportó una conclusión fundamental: todas las célula derivan de la replicación (división) de células preexistentes. Los virus se consideran una excepción a la teoría celular porque ellos son considerados organismos vivos (aunque esta consideración está sujeta a debate), los cuales poseen un nivel estructural y de organización menor al nivel de una célula. Respecto a este punto, cabe aclarar que los virus son parásitos intracelulares los cuales derivan (descienden evolutivamente) de organismos celulares y por lo tanto es posible asumir a sus orígenes como subproductos de los genomas de las células (es decir, de organismos celulares).
