How can polyploidy cause speciation in plants?

Biology
1 answer:
scoundrel [369]3 years ago
8 0

Answer:

Polyploidy is common among plants and has been a major source of speciation in the angiosperms. If through polyploidy the plant duplicates the chromosome set inherited from each parent meiosis can occur because each chromosome will have a homologue derived from its duplicate set.

Drag each tile to the correct location on the chart. What are the pros and cons of sexual and asexual reproduction?
levacccp [35]

Answer:

Sexual reproduction:

Pros: leads to greater genetic variation.

Cons: requires more time and energy.

Asexual reproduction:

Pros: Does not require finding a mate.

Cons: Produce less genetic variation.

Explanation:

Sexual reproduction is a type of reproduction in higher organisms, in which new individuals are formed by combining genetic information from two different types (sexes) of individuals.

Advantage: Sexual reproduction leads to higher genetic variation due to recombination between genetic material of female and male gamete during meiosis.

Disadvantage: Sexual reproduction is a time and energy consuming process as it needs interaction between mates and organisms which are produced sexually require more time for development.

Asexual reproduction involves formation of new organisms from a single parent organism without gamete fusion.

Advantage: Asexual reproduction requires less time and energy as it does not require finding a mate.

Disadvantage: Asexual reproduction produces less genetic variations as it involves only parent organisms (no mixing of genetic information) and the only source of variations are random mutations.

Electrons in the outermost energy level are usually involved in chemical reactions which are called ___________________ .
Elena-2011 [213]

Answer:

Chemical bonding

Explanation:

Outer most shell's electrons are called valence electrons and they are responsible for the formation of chemical bonds either ionic or covalent when atoms react with each other.

Outer most electrons hold immense importance in the type of chemical bonding an atom will go through in the formation of a molecule.

For example, sodium has only one electron in outermost shell so it is very hard for sodium to share electrons and become stable. Therefore, it never goes for covalent bonding but only goes for ionic bonding where it gives off one electron to another atom (say chlorine who has 7 electrons in outermost shell) and in this process sodium chloride is formed and both sodium and chlorine get stable electronic configuration.

Please see picture for better understanding. Therefore, we can say that  Electrons in the outermost energy level are usually involved in chemical reactions which are called chemical bonding or formation of chemical bonds.

Hope it help!
