This is a true statement. An electron closer to the nucleus would be difficult to remove because the electronegativity of the atom would be greater.
Answer: the beetle is neither harmed nor helped by the mite.
Explanation:In this case, the mite benefits because it gains transportation from the beetle. If the beetle is neither harmed nor helped by the mite, then the relationship between the mite and the beetle would be an example of commercialism.
Answer:
G and K
Explanation:
Crossing-over is a genetic phenomenon that occurs in meiosis, specifically, Prophase I. It is when chromosomal segment (genes) are exchanged between non-sister chromatids of homologous chromosomes. Crossing-over occurs only to genes that are UNLINKED i.e. genes located on different chromosomes or far apart on the same chromosome.
This unlinked genes are said to have the highest RECOMBINATION FREQUENCY. Crossing-over allows genes on the same chromosome but far apart from each other, assort independently, which allows alleles to be recombined on the same chromosome. This phenomenon does not occur to genes that are close on the same chromosome as they will be inherited together as a unit.
In this case, G and K are the farthest apart, hence, they will have the highest RECOMBINATION FREQUENCY i.e. the likelihood for homologous crossing-over to take place during meiosis.
Answer: False.
Meat is a good source of protein. There are nine essential amino acids which are required under special conditions like illness.
These are- Histidine, Leucine, Isoleucine, Valine, Threonine, Methionine, Lysine, Phenylalanine and Tryptophan. They cannot be synthesized by the body and therefore need to be taken from external protein sources.
Since meat contains all the essential amino acids, therefore it is considered as a good source of protein. Hence, the given statement is false.
