One will be due to climatic change or it might be coz of evolution
Answer:The best explanation is;
The materials undergo decay when they collide, which results in the heating and subsequent melting and rising of materials
Explanation: A protoplanet is an embryo formed in a protoplanetary disc which has passed through a melting phase that enables the formation layered interior
In protoplanets the effects of partial melting of the components due to heating produced by radioactive decay and pressures from forces of gravity there is segregation of the melt and igneous composition such that the heavier melted metal can sink and be over laid by the lighter igneous rocks
Therefore, the best explanation is that the materials undergo decay when they collide, which results in the heating and subsequent melting and segregation by the sinking of the heavier melted materials and rising of the lighter igneous materials.
Answer:
synapse
Explanation:
We know that nerve impulses, signals, must pass from cell to cell for a response to a given signal to occur. For this to happen, the presence of a specialized region called the synapse is required. Synapse is the structure that allows signals to be transmitted from one nerve cell to another.
Synapse can be defined as the region of proximity between the end of a neuron and a neighboring cell, where nerve impulses are transformed into chemical impulses due to the presence of chemical mediators.
They are autotrophs.
The process by which they get energy is called Photosynthesis - it is used by plants, algae and certain bacteria to harness energy from sunlight and turn it into chemical energy.
Answer:
e. All of the choices are correct.
Explanation:
Bacteria are present almost everywhere on Earth. Many bacteria like cyanobacteria play an important role in fixing the atmospheric carbon in the form of an organic molecule. These organic molecules then used to gain energy.
Many nitrogen-fixing bacteria like Rhizobium, Azotobacter, etc plays an important role in providing nitrogen to plants which is important for their growth. Many bacteria decompose organic matter into simpler form and recycle the nutrients present in them.
So bacteria like <em>Pseudomonas putida</em> decompose waste and clean the environment, therefore, they also help in bioremediation. So the correct answer is e. All of the choices are correct.
