en donde se produce La citocinesis
La citocinesis ocurre al final del ciclo celular después de la mitosis o meiosis. En la división de células animales, la citocinesis ocurre cuando un anillo contráctil de microfilamentos forma un surco de escisión que pellizca la membrana celular por la mitad. En las células vegetales, se construye una placa celular que divide la célula en dos.

Could someone please tell me if this is mold or not? I think it is but honestly I know nothing about that.
Answer:
It would be Penicillium or Aspergillus, if it is even mold. They are some of the fastest growing molds (usually within 24 to 48 hours) and require very little moisture for their colonies to develop. I haven't ever seen mold
It's usually not possible for you to remove it from wood, but you are going to want to call someone to get rid of it. You don't know what exactly it is and buying fungicide may help.

energy is available
to the secondary
consumers?
Answer:
13000 would be avalable because 10% is taken every time it is eaten so 65,000 with 10% taken out twice (20% of 65,000) is only 13,000 kcal available to the secondary consumers.

why is it important for plant's to store food?
Answer:
Storing the food helps them to use it in winter and survive because there is very little sunlight available and so they photosynthesis less. ... When they have extra food they store it in their seeds and when the seed grows it gets it's food from the plant until the plant is able to photosynthesis and produce its food.
Answer:
It's important for plants to store food, as food is a source of nutrition, which is necessary for survival. Rather than just eating the food, storing it is a good way to ensure nutrients during droughts or other harsh conditions that make it hard to find food.

Explanation:
6:
Answer: Newton's first law of motion,
Explanation: Inertia is the tendency of an object to resist a change it its motion. Describe how inertia affects motion. If an object is already at rest, inertia will keep it at rest. If the object is already moving, inertia will keep it moving.
7:
Answer: The second law
Explanation: The second law shows that if you exert the same force on two objects of different mass, you will get different accelerations (changes in motion). The effect (acceleration) on the smaller mass will be greater (more noticeable).
8.
Answer: Newton's Second Law
Explanation: The second law of motion explains the relationship between force, mass, and acceleration. The law states that the acceleration of an object depends on the mass of the object and the amount of force applied. Newton's second law of motion is also called the law of force and acceleration.

When designing an experiment, you come up with the question: How does the amount you talk to a plant help it grow? Which would be the best hypothesis
Answer:
The correct answer is - "If you increase the amount you talk to plants, then they will grow taller"
Explanation:
A hypothesis is a proposed or assumed explanation for the natural system or problem. It forms on the pre-existed or known data or knowledge. A good hypothesis should have the ability to relate to dependent and independent variables.
In this case, the best hypothesis would be "If you increase the amount you talk to plants, then they will grow taller" as it relates to the dependent and independent variables that are the growth of the plant and talking to the plant respectively.
