Possibility of acid rain will increase
Answer:
A Mutations are sometimes helpful, sometimes harmful, and sometimes neutral.
Explanation:
I did the test.
Answer:
a.Many mitochondrial genes resemble proteobacteria genes, while the genes in the chloroplast resemble genes found in some photosynthetic bacteria.
c.Mitochondria and chloroplasts both have their own circular DNA and 70S ribosomes that are similar to those found in bacteria.
d.Mitochondria and chloroplasts replicate by a process similar to mitosis.
Explanation:
Endosymbiotic theory states that mitochondria and chloroplast which are organelles of eukaryotic cells were once independently living micro-organisms but with due course of time eukaryotic cells engulfed them and they become an integral part of these eukaryotic cells.
The resemblance between mitochondrial genes with those of proteobacteria and chloroplast genes with photosynthetic bacteria strongly support endosymbiotic theory. Apart from this, the presence of their own DNA that too circular just like prokaryotic microbes and 70 S ribosomes also support this theory. Also just like prokaryotic cells, before cell division mitochondria and chloroplasts undergo replication by means of a process known as binary fission.
Answer:
The correct answer is: (A).
Explanation:
- In the question, it is mentioned that the algae can grow under the conditions of "enough sunlight" and "enough nutrients".
- Sunlight reaches the algae, by first falling on the surface made up of ice and snow and then refracting from there into the top layer of the ice where the algae grows.
- However, the capability of both snow and ice to reflect sunlight is far more than that of refracting sunlight.
- Therefore, the amount of light received by the algae is similar in absence or presence of the layer of snow on the top layer of ice.
- However, on deposition of snow on the layer of the ice, the weight of the ice increases and it sinks below into sea water.
- This allows more nutrient rich sea water to percolate into the ice and reach the algae.
- The algae receive more nutrients from the sea water and hence is capable undergoing better metabolism and growth.
- Hence, more algae are produced under such a situation.
Thermal energy is transferred during heating.
What is thermal energy?
- Thermal energy refers to the ability to do work. As such thermal energy can also be defined as the ability of something to do work as a result of the movement of its particles.
- In other words, thermal energy is the energy possessed by an object or body by virtue of the movement of its constituent particles.
- It is the total internal kinetic energy of an object due to the random motion of its atoms and molecules.
- Thermal energy is a type of kinetic energy owing to the fact that it results from the movement of particles. Kinetic energy is the energy possessed by an object due to its motion.
- Thermal energy forms the foundation of the study of heat energy and thermodynamics. It is one of the oldest forms of energy utilized by mankind.
- Its usage existed even before petroleum and nuclear power sources were discovered.
