Biology

Answer:

The correct answer is option D.  Light and some other factors are necessary for chlorophyll production

Explanation:

By this experiment, it is clear that light is the major factor that helps in the production of chlorophyll in seedlings or plants. In this study, placing the seeds in the light turns 75 seedlings green which is possible by the production of the green pigment, chlorophyll only. So, it is proved that light is a key factor in the production of chlorophyll.

Besides light, there must be some other factors (mineral nutrition and chemical metabolites) that also play role in the production of chlorophyll or increase or decrease of the chlorophyll production as few seedlings did not turn green in the study.

Como se representa la molecula de agua y en cuantas partes
Hitman42 [59]
<span>¡La opinión de un químico sobre el mundo no es tan estrecha como se podría pensar! Sí, empezamos con el átomo, y luego pasamos a las reglas que gobiernan los tipos de unidades estructurales que se pueden hacer con ellos. Se nos enseña tempranamente a predecir las propiedades de la materia en masa de estos arreglos geométricos. Y luego llegamos a H2O, y estamos sorprendidos al descubrir que muchas de estas predicciones están muy lejos, y que el agua (y por implicación, la vida misma) ni siquiera debería existir en nuestro planeta. Pero pronto aprendemos que esta pequeña combinación de tres núcleos y ocho electrones posee propiedades especiales que lo hacen único entre los más de 15 millones de especies químicas que conocemos actualmente. Cuando nos detenemos a reflexionar sobre las consecuencias de esto, la química pasa de ser una ciencia arcana a un viaje de maravilla y placer mientras aprendemos a relacionar el mundo microscópico del átomo con el mundo mayor en el que todos vivimos.</span>

Which is a limitation of a scientific model?
iren [92.7K]

Answer:

The correct option is<em> D)  Models are not the "real thing" so it will never correctly represent the system in all respects.</em>

Explanation:

Scientific modelling can be described as a representation of the scientific theories or concepts in a way that can be better understood. Scientific models makes it easier to understand what physical, chemical or mechanical activity is taking place. Even mathematical representation comes under scientific modelling.

As models are not the real, hence they cannot be considered to be perfectly accurate. A model can never mark up to the complexity of nature.

almond37 [142]
<span>This form of providing energy for the storage and transport within the cell is called as Mitochondria. The energy production is done threw respiration and help regulate the cellular metabolism. Mitochondria are organelle that is present in the cytoplasm, not nucleus. Exercising your body can boost the density of mitochondria.</span>

“The study of cell biology is directly
Marat540 [252]

Answer:

I agree.

Explanation:

Cell biology and technology are so connected that there is even a science called biotechnology, which is the literal union of these two strands.

Biotechnology is an area that aims to develop biological products and processes with the help of science and technology. The United Nations (UN) classifies biotechnology as "any technological application that uses biological systems, living organisms, or derived beings, to manufacture or modify products or processes for specific uses".

Biotechnology covers different areas of knowledge that include basic science (such as molecular biology, microbiology, etc.), applied science (such as immunological, chemical and biological techniques) with different technologies (such as information technology, robotics and process control).

I dii ok not under stand this please help me!
satela [25.4K]

Answer:Answer:

For 1: The correct answer is Model 1, 2, and 4.

For 2: The correct answer is Option 1.

Explanation:

For 1:

An element has 3 subatomic particles: electrons (E), neutrons (N) and protons (P).

Atomic number is defined as the number of protons or number of electrons.

Atoms having same number of protons are same. From the given models, Model 1, 2 and 4 have 2 protons with different neutrons. Hence, these models belong to same element.

For 2:

A compound is defined as a substance in which two or more types of elements combine in a fixed ratio. For Example:  is a compound made out of atoms of carbon and oxygen.

Hence, the correct answer is Option 2.
