I think the correct answers from the choices listed above are options B and C. The two main sources  that lead to increased genetic variation would be Gamete mutations and recombination. <span>Gametes mutations leads to change in DNA information, recombination allows mixture of genotypes.</span>

Answer:

B) Gamete mutations, C) Recombination

Explanation:

Any random changes in the DNA of gametes are called as gamete mutations. These mutations are transmitted to the next generation via gametes and thereby the genetic variations are increased.

Recombination is the production of new gene combinations. Crossing over during meiosis I of gamete formation add new gene combinations to gametes. Random fertilization of these gametes add even more genetic variations to the progeny.

stiks02 [169]

Answer:

Mushrooms and plants all need energy to grow. But the sources of their energy differs.

Explanation:

Sun is the ultimate source of energy for any living organisms to grow and make their food. While plants takes energy from the sun directly and make their food, while the mushrooms which is not a plant does not take energy from the sun directly.

Mushrooms utilizes the energies which is collected by the different organism which collects their energy from the sun such as organisms like the bacteria and plants. Mushrooms grow well in darkness as darkness helps to retain moisture. Mushrooms does not have chlorophyll to make food.

Plants have chlorophyll. And they direct absorb energy from the sun light to make their own food.

Dmitriy789 [7]

Terms matched with the right definitions.  

1. An organism that can make its own food – Autotroph

2. A symbiotic relationship between two organisms in which one species benefits and no effect is apparent to the other species – Commensalism.  

3. A cell that has a membrane-bound nucleus and/or organelles as its major characteristic -Eukaryote.  

4. The study of organisms that are too small to be seen with the naked eye - Microbiology.  

5.  A disease-causing organism - A germ pathogen.  

6. A one- or few-celled organism with chromosomes; may have characteristics of both animals and plants – Protist.


An autotroph is an organism that produces its own food from simple substances available in its environment. Autotrophs usually use inorganic chemical reactions or light energy in producing their food and are usually the producers in a food chain. Examples of autotrophs are plants and algae.


Commensalism is a type of relationship between organisms of two species where one organism benefits from the relationship and the other organism is not affected by it (neither benefits nor harmed).
