A space used in industry or research settings that has a controlled level of contaminants is called a __________.
Answer:
Clean room.
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
Cause and effect can be defined as the relationship between two things or events in which an occurrence one (cause) leads to the occurrence of another (effect).
Hence, a space used in industry or research settings that has a controlled level of contaminants is called a clean room.
A clean room refers to environment or laboratory that is typically free from dust, pollution or any form of contaminants, used for carrying out experiments and manufacturing processes.
Which of the following characteristics is shared by both primary and secondary consumers?
Uses the Sun’s radiant energy to produce food
The first step in any food chain diagram
Eats only plants to gain needed energy
Gains energy by eating other living things
The characteristic that is shared by both primary and secondary consumers is that they gain energy by eating other living things. Therefore, option D is correct.
What are consumers in an ecosystem?The primary consumers are the organisms that devour the producers. They are numerous and often modest in size. Herbivorous animals are the primary consumers (vegetarians). The organisms known as secondary consumers are carnivores that consume the primary consumers. Secondary consumers are consumed by tertiary consumers.
Herbivores, carnivores, omnivores, and decomposers are the four different categories of consumers in ecology.
The characteristic that is shared by both primary and secondary consumers is that they gain energy by eating other living things. Therefore, option D is correct.

Which characteristics of bacteria help them infect other organisms? Check all of the boxes that apply.
The complete question is as follows:
Which characteristics of bacteria help them infect other organisms? Check all of the boxes that apply. Bacteria reproduce quickly. Bacteria have a protective layer called a capsule. Bacteria can evolve quickly because they can pass on genetic information. Bacterial infections cause symptoms that transfer the bacteria to new hosts.
Answer:
The correct answer is - all options are correct.
Explanation:
Bacteria can infect other organisms due to their different type of characteristics. These microorganisms infect the host cell by attacking them and increase their number rapidally. Host cell tries to kill these bacteria but these bacteria cells have a tough protective layer around their body prevent from any chemical or immune response.
Bacteria cells have a great feature to evolve fast in few generations which helps them developing resistance according to the condition for their survival.

Estrogen is one of the hormones produced by human females. Identify one organ that produces estrogen and state one specific function of estrogen in a human female.
Answer:
The ovaries. They produce the women's eggs.
Explanation:
Estrogen helps control the menstrual cycle and also helps childbearing.
The hormone estrogen is highly produced by ovaries, while some of the estrogen is also produced by the adrenal gland.
What do you mean by Hormone?Hormones may be defined as the chemical substances which are secreted by the endocrine glands and are transported to the target site via the bloodstream.
There are numerous functions of the hormone estrogen found in the body of a human female.
It helps in stimulating the growth of the egg follicle. It regulates the menstrual cycle. It also controls the thickness of uterine mucus secretions.
Therefore, it is well described above.

The student hypothesizes that green pod color in pea plants is dominant and yellow pod color is recessive. Which observation would disprove this hypothesis?
Two plants with green pods produce offspring with green pods.
Two plants with yellow pods produce offspring with green pods.
Two plants with green pods produce offspring with yellow pods.
Two plants with yellow pods produce offspring with yellow pods.
Answer:
c
Explanation:
got it right on edgenu1ty
The student hypothesizes that the green pod color in pea plants is dominant and the yellow pod color is recessive. An observation that would disprove this hypothesis is that two plants with yellow pods produce offspring with green pods, which is the second option.
What is the importance of dominance?The complete dominant allele will express itself in the heterozygous condition because it will suppress the recessive allele and express itself. Here, the green is dominant over the yellow, so the green can be purebred or can have a heterozygous condition, so the green pod having a heterozygous condition can produce both the green and the yellow pods. The yellow pods are recessive, so they can only produce yellow offspring, not green offspring, as they are only expressed in the purebred recessive forms.
Hence, an observation that would disprove this hypothesis is that two plants with yellow pods produce offspring with green pods, which is the second option.

Los procesos de respiración aerobia celular y fotosíntesis, procesos considerados indispensables para la vida en la tierra, de los que es correcto afirmar que Son de carácter antagónico, es decir el cloroplasto ejecuta reacciones anabólicas y la mitocondria catabólicas. La respiración celular sólo la realizan los seres eucariotas del reino de los vegetales. Ambos son realizados por los seres considerados eucariotas. Ambos son realizados por eucariotas pertenecientes al reino de los vegetales
Respuesta:
Las opciones correctas son: a) son de carácter antagónico, es decir el cloroplasto ejecuta reacciones anabólicas y la mitocondria catabólicas; y d) ambos son realizados por eucariotas pertenecientes al reino de los vegetales.
Explicación:
La fotosíntesis y la respiración celular son procesos de carácter antagónico porque la fotosíntesis es anabólica y la respiración celular es catabólica. La fotosíntesis consiste en la producción de moléculas complejas a partir de moléculas simples (proceso anabólico), mientras que en la respiración celular se degradan moléculas complejas y se las convierte en moléculas más simples (proceso catabólico).
Ambos procesos son realizados por los eucariotas del reino de los vegetales, pero los eucariotas del reino animal sólo realizan respiración celular, ya que no tienen cloroplastos. Esta diferencia tan importante existe porque los animales pueden moverse para conseguir comida (heterótrofos), mientras que los vegetales necesitan producir sus propios nutrientes haciendo uso de la fotosíntesis (autótrofos). Más allá de esta diversidad, todos los eucariotas realizan respiración celular para producir energía en forma de ATP.

The smallest and the most basic unit of life is the cell. Living organisms that are made of just one cell are said to be unicellular while those that are made up of multiple cells are said to be multicellular. Many unicellular organisms are some of the smallest living organisms to exist in nature. They cannot be seen with the ordinary eyes, except with the aid of microscopes.
