A purple-flowered plant that
carries two different color traits such as purple and white is heterozygous.
Heterozygous<span> means that an organism has two different
alleles of a gene. </span>I am hoping that this answer has satisfied
your query and it will be able to help you in your endeavor, and if you would
like, feel free to ask another question.
If crossing over did not occur during meiosis, there would be less genetic variation within a species. With crossing over, potentially every chromosome could consist of a combination of both maternal and paternal alleles, which, along with random segregation of chromosomes during anaphase II, would result in a nearly limitless number of genetic variations between related individuals and within a species.
Without crossing over, each chromosome would be either maternal or paternal, greatly reducing the number of possible genetic combinations, which would greatly reduce the amount of genetic variation between related individuals and within a species.
And as genetic variation decreases, the species has a very less chance to evolve and adapt as natural selection.
Answer:
c. somatic and autonomic systems
Explanation:
The major divisions of the pheripheral nervous systems are the somatic and autonomic systems.
Nervous system is made up of series of nerves that coordinates all the actions of an organism using electrical signals.
It is made up of two parts;
- Central nervous systems
- Peripheral nervous systems
The central nervous systems is made up of the brain and the spinal chord.
The peripheral nervous systems are the nervous systems outside the central nervous systems.
It is generally divided into somatic and autonomic systems
Answer:
Enzymes serve as catalysts to many biological processes, and so they are not used up in reactions and they may be recovered and reused. However, in a laboratory setting, reactions involving enzymes can leave the enzyme unrecoverable. This process makes the enzyme at once less reactive but more stable.
