A que se llama tierra de usufructo???
Ayuda
Answer:El usufructo (del latín: usus fructus, «uso del fruto»)1 es un derecho real de goce o disfrute de una cosa ajena. El Código Civil de España define este derecho en su artículo 467 como "el derecho a disfrutar los bienes ajenos con la obligación de conservar su forma y sustancia, a no ser que el título de su constitución o la ley autoricen otra cosa" .2 Por consiguiente, la persona titular del usufructo es mero tenedor respecto de la cosa pero no su dueño ni poseedor. Tiene la mera tenencia sobre la cosa, pero no la propiedad. Puede utilizarla y disfrutarla, es decir, obtener sus frutos o rendimientos, sean en especie o dinerarios, pero no puede disponer libremente de ella por no ostentar el derecho de propiedad sobre aquella. Es la razón de que no pueda enajenarla ni disminuir su valor sin el consentimiento del titular de la propiedad.

Where does the light and thermal energy given off when burns food come from?
A Light and thermal energy given off from burning food comes from the lighter used to light the food.
B. Light and thermal energy given off from burning food is converted from the chemical energy stored in
the food.
C. Light and thermal energy given off from burning food comes from oxygen.
D. Light and thermal energy given off from burning is created when food burns.
3. Why do two grams of fat provide a different amount of energy than two grams of carbohydrate?
Answer: B
Explanation: Because Light and thermal are two different things of heat and if one of the cores of heat gets any cooler than it is than it may burn out and there wwill no longer be heat so the food brin come in at the middle (Core) of the heat and just like a microwave it had different heats but its core of the heat stays the excact same

A person sees a ball and kicks it, in part because of actions of the nervous system. Using the parts of the nervous system listed, describe the path of nerve impulses that cause the person to (1) see the ball and (2) kick the ball.
Answer:
In the case of seeing a ball and kicking it can be expressed in the actions of the nervous system as follows:
Part 1. Eyes see the ball and send signals with the help of sensory neurons that carry this message to the spinal cord.
PArt 2. The spinal cord processes the information and sends an "impulse" of kicking the ball that will transfer to motor neurons that transfer it to the brain and then muscles.
Sensory neurons --> spinal cord --> motor neurons --> brain---->leg muscles

Which of the three components that plants need do we provide?
Answer:
Plants, like all living organisms, have basic needs: a source of nutrition (food), water, space in which to live, air, and optimal temperatures in order to grow and reproduce. For most plants, these needs are summarized as light, air, water, and nutrients (known by the acronym LAWN).
Why is mitosis necessary during the development of a human?
Answer:
Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.

In the carbon cycle, atmospheric carbon dioxide is converted into organic material by which process? a) transpiration b) cellular respiration c) decomposition d) photosynthesis
Answer:
The correct answer is d) photosynthesis
Explanation:
Photosynthesis is the process by which plants transform inorganic matter from their external environment into organic matter that they will use for their growth and development. It basically consists of the production of sugars from C02 (carbon dioxide) in the air, minerals and water with the help of sunlight. In this reaction, oxygen molecules are released and carbohydrates are fixed in the plant. Plants absorb sunlight through a pigment called chlorophyll. Not only can plants fix CO2, so do certain bacteria and green algae. Photosynthesis is conditioned by internal plant factors and external or environmental factors.

Answer:
abiotic
Explanation:
abiotic - nonliving components of an ecosystem that can affect the living organisms.
Temperature is a nonliving component and it affects the organisms that live within a certain environment.
Therefore the answer is Abiotic
Reasons its not the other answers:
Biotic factors must be living things
Temperature is not a living thing therefore Biotic cannot be the answer
Same with living, temperature is not living therefore the answer cannot be living.
Temperature plays a huge role in an ecosystem therefore it is considered an important component and the answer cannot be unimportant.
