The best statement to your question, according to the law of conservation is:

Before and after a given process, the amount of energy will remain the same, even if it is changed to different forms of energy.

→ Note that this ↑ only apllies to the law of conservation. Other laws, for example, state that some energy is lost during a process.

Hope it helped,

Happy homeowrk/ study/ exam!

What do you think will happen to the planet if plants are drastically reduced in population or become extinct?
Inessa [10]

Answer:

If all the plants on earth died, so would the people. ... When green plants make food, they give off oxygen. This is a gas that all animals must breathe in order to stay alive. Without plants, animals would have no oxygen to breathe and would die.

During what stage does land get ready for the arrival of a new species
34kurt

Answer

           The correct option is B.

Explanation

          Ecological succession of any species is composed of following stages:

A. Migration

            The movement of species from one place to another location for the purpose of setting permanently o temporary is known as migration . Forexample

             Siberian crane (<em>Leucogeranus leucogeranus</em>) that live in the arctic tundra of eastern and western Russia. The eastern population of birds migrate to china while western population of these birds migrate to Iran, India and Nepal during winter season.

B. Ecesis

         The complete establishment of species in new habitat that was completely barren or left barren due to some catastrophe is known as Ecesion. This process is dependent upon the climatic, edaphic and biotic factors. The success of plant depend upon some of the adaptations to withstand the unfavorable conditions which includes both biotic and abiotic conditions.

Forexample

               The process of succession in xerosphere start on barren area from pioneer stage covered by crustose lichen, then foliose lichen followed by moss stage, herbaceous stage and a last by shrub stage.

C. Nudation

       The initiation of new species by major environmental disturbance such as volcano eruption is known as Nudation.

D. Reaction

            It represents the effect of established species on the habitat. Forexample plants alter habitat condition as they grow. They extract raw materials from the environment in large amounts and return metabolic wastes. The waste accumulates in large amounts and differ from the original raw materials, thus altering the environment.  

E. Competition

             The phenomenon which involves struggle for existence between two or more individuals growing in same area, that make excessive demand that are similar in nature on the soil is known as competition.

Such struggle may be in between same species or different species. The competition may be interspecific or intraspecific. Because of completion the weak individuals are eliminated as strong ones are retained.

A cell has a defect in its receptor for growth factors, preventing growth factors from attaching to and signalling the cell. Bas
morpeh [17]

Answer:

Option B

Explanation:

B. The cell will grow uncontrollably and continue to divide as long as it has food.

Cell growth is theeoretically stimulated by the binding of growth factors to their receptors using signaling pathways.

These pathways are regulated by proteins which are encoded for in the genes.

The gene that controls the regulation of these pathway when mutated produce malfunctioning signaling protein thus not allow for regulations of the cell cycle causing uncontrollable cell division. These mutated genes are called oncogenes.
