The flow of energy is always one way. If we start at the sun and the sun’s energy moves to a plant, then the plant cannot transfer that energy back into the sun. The flow of energy is always controlled bc there is always a visible path it takes.

Elina [12.6K]

Centrosomes, also called microtubule organizing systems, release the microtubules that arrange the chromosomes along the metaphase plate.

Near the Golgi, there are 9,0 microtubule multiplets that produce microtubules. In order to sustain a dynamic movement process and for the centralized organization of chromosomes along the meiosis,plate, these microtubules bind to the kinetochores of chromosomes utilizing dyneins and kinesins.

During metaphase, chromosomes are organized over the metaphase plate with the help of microtubules released from complexes on various cell surfaces. Microtubules are continuously destroyed and rebuilt in a dynamic process until chromosomes are centrally organized.

Two heterozygous dominant parents for attached earlobes are crossed to predict the traits of their offspring. What is the ratio
photoshop1234 [79]

Answer:

A - 3:1

Explanation:

In order to determine what number of offspring will have attached earlobes, we must make a Punnett table. We know that attached earlobes are the dominant gene, and we know unattached earlobes are recessive.

| P | p

——————-

P | PP | Pp |

——————-

p | Pp | pp |

As we can see, only one out of the four squares has two recessive genes. Therefore, our answer would be A - 3:1.

lions [1.4K]

Answer: The answer is B: The enzyme's active site binds to and stabilizes the transition state, which decreases the activation energy of the reaction.

Explanation: An enzyme is a biological molecule which speeds up the rate of chemical reactions in the body (reactions within cells). They are proteins.

    The transition state is the transition from substrate to product. The molecule is no longer a substrate but also not yet a product.

The enzyme is able to speed up the reaction by stabilizing the transition state. The transition state's energy is also the activation energy in terms of reaction. The activation energy is the minimum energy that is required to break some bonds of the reactants in order to turn them to products.

Reika [66]
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide in the process of respiration, which is then used in photosynthesis. While water is broken down to form oxygen in photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.  ATP is manufactured as a result of several processes including fermentation, respiration and photosynthesis.
