Answer:
Having the light reaction components in close proximity speeds up the process. Electrons move from one protein to the next in sequence. If the proteins had to 'swim' around to find the next part of the electron transport chain, then the ATP would form at a much slower, inefficient rate.
Which item in the photo is a good thermal insulator, and why?
A. The plastic handle, because its electrons dont move freely
O B. Human skin, because it is made up mostly of water
C. The metal pan, because its electrons move quite freely
D. The cut vegetables, because they contain a lot of water
Answer:
free electrons can go through the material such as they are most through loses send the water inside the vegetables of human skin is not very good inspiration because its water if you had to take a warm shower and then come out you feel very cold

Answer:
the second answer choice
25% red, 50% pink, and 25% white
Explanation:
construct a punnett square with the genotype RW and cross them to get genotypes of RR, RW, RW, and WW.
RR is red and occurs once so that is a 25% chance (1/4)
RW is pink and it occurs twice so that is 50% (2/4)
WW is white which occurs once and it is another 25% (1/4)
can someone pls help me with this
Answer:
t= log2(2048)
The logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x. In this case:
[tex] {t}^{2} = 2048[/tex]
[tex]t = \sqrt{2048} = 45.3h[/tex]

How is energy produced in the sun? Draw a diagram to explain the processes.
Answer:
hope it's help uu
Explanation:
if wrong then sry
Answer:
The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. During this process huge amount of energy is created.
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.

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.

Explanation:
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.

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.
