Evolution can be defined as the heritable changes occurring in the populations over the time through the successive generations. The process of evolution is helped by the natural selection of the favorable traits and the elimination of the unfit traits from the environment. An increased proportion of favorable characteristics in the offspring will show the proof of successful evolution.
Hence, the correct answer is 'option 3 - an increase in the proportion of offspring with favorable characteristics'.
Legumes, a type of plant, require Rhizobia, a type of soil bacteria, to survive since these organisms fix nitrogen during photosynthesis. Rhizobia use the legumes for food. If Rhizobia suddenly became extinct the legumes become extinct too because for the growth of legumes rhizobia is required and if they are extinct than legumes also extincted.
A legume is a plant from the family of fabaceae, they are basically pulses that are the rich source of protein. Legumes are grown agriculturally, primarily for human consumption, for living and forage and silage.
Legumes are chickpeas, peanuts, green peas, black beans, kidney beans, navy beans and lima beans.
Legumes are plants refers to a plant from the family fabaceae that would include leaves, stems, and pods.
Rhizobium is a gram- negative soil bacteria that fix nitrogen in the soil and they are also known as nitrogen fixing bacteria and they help to fix nitrogen of soil during the process of photosynthesis.
The rhizobium is from class alphaproteobacteria, Genus rhizobium and order hyphomicrobiales, phylum pseudomonadota and domain bacteria.
Therefore,Legumes, a type of plant, require Rhizobia, a type of soil bacteria, to survive since these organisms fix nitrogen during photosynthesis. Rhizobia use the legumes for food. If Rhizobia suddenly became extinct the legumes become extinct too because for the growth of legumes rhizobia is required and if they are extinct than legumes also extincted.

The answer is: the legumes will extinct, too.
It is known that plants cannot directly use atmospheric nitrogen. But, some legumes have a symbiotic relationship with bacteria that live in their root system. These bacteria are called Rhizobia and have the ability of nitrogen-fixation. In the root nodules, they use atmospheric nitrogen to convert it into ammonia, and later to ammonium, which can be used by plants. When legumes die, nitrogen from their remaining is released back to the soil where it is available to the other plants.
So, if Rhizobia suddenly became extinct, the symbiotic relationship between will be interrupted. The legumes will not be able to use atmospheric nitrogen without the help of Rhizobia, and eventually, they will extinct, too.
Answer:
to increase their chance of survival
Explanation:
The replicate strand of the given strand of DNA is TTAGTACCT as per the complimentary base pairing in DNA.
DNA is a hereditary material which is present in human beings as well as all other living organisms. Every cell which is present in an organism's body has DNA which is the same. Most of the DNA is situated in the cell's nucleus and small amount of it can be found in the cell's mitochondria as well.
Information which is stored in DNA is stored as codes made up of four chemical bases namely, adenine, thymine , cytosine and guanine.Human DNA consists of 3 billion bases .The order of the bases determines information which is required for building and maintaining an organism.
DNA bases are capable of pairing up with each other. Adenine pairs with thymine and guanine pairs up with cytosine .Each base is also attached to a sugar molecule and a phosphate group. A base, phosphate sugar are together called as nucleotides.
