One possible explanation for the evolutionary survival of homosexuality is antagonistic pleiotropy. what would that mean, as app

lied to homosexuality?

Ivenika [448]3 years ago

<span>If the evolutionary survival of homosexuality is due to antagonistic pleiotropy then there has to exist a genetic basis for homosexuality. This is because antagonistic pleiotropy refers to when one gene controls for more than one trait where at least one trait is beneficial and at least one trait is detrimental to the organisms survival. In this case, homosexuality would be the trait that is detrimental to the organisms survival and there would need to exist another beneficial trait that is controlled by the same gene.</span>

What is homeostasis... Be discriptive
Semenov [28]
<span>(I got this from my handbook dictionary)
"the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes."

What that basically means is that homeostasis is the ability to respond to certain environments. It is how you respond to environmental changes and how you basically adapt to it.. that's where the idea of response and adaption came from.

Hope this Helps!! (I had a quiz on this once)

Which mutations is most likely to cause a phenotypic change?
melomori [17]

The question is incomplete. The complete question is as follows:

Which of the following mutations is most likely to cause a phenotypic change?

A) a duplication of all or most introns

B) a large inversion whose ends are each in intergenic regions

C) a nucleotide substitution in an exon coding for a transmembrane domain

D) a single nucleotide deletion in an exon coding for an active site

E) a frameshift mutation one codon away from the 3' end of the nontemplate strand

Answer: D) a single nucleotide deletion in an exon coding for an active site

Explanation:

Deletion or insertion of a single nucleotide in an axon coding for an active site is called frameshift mutation.

The sequence of codons is read during translation, in order to synthesize a amino acids chain and form a protein from the nucleotide sequence. Frameshift mutations occur when the usual codon sequence is broken by the deletion or addition of one or more nucleotides. For example, if only one nucleotide is removed from the axon sequence during the RNA splicing process, then there will be a disrupted reading frame for all codons before and after the mutation. This may result in several incorrect amino acids being introduced into the protein. Disruption in protein sequence will cause phenotypic change.

Hence, the correct option is D) a single nucleotide deletion in an exon coding for an active site .

Which nims command and coordination structures are offsite locations where staff from multiple agencies come together? answer ic
ivolga24 [154]

Emergency Operations Centers (EOCs) are the National Incident Management System (NIMS) command and coordination structures that are offsite locations where staff from multiple agencies come together.

Emergency operations center (EOC) is a control facility that functions mainly for incident response. This center serves as a central intelligence arena where response team personnel and decision makers gather and analyze extremely important information, organize response activities, make decisions that guards life and property, communicates with staff and response team personnel and ensure the consistent existence and operation of the organization.
