The frequency of the recessive allele for the left handle will be in this case equal to q^2 = 0.25 >> q = 0.5.
<h3>What is the Hardy Weinberg principle?</h3>
The Hardy Weinberg principle is a model used in population genetics to estimate genotypic and allele frequencies.
The Hardy Weinberg principle states that the sum of the dominant allele and the recessive allele in a population is equal to 1 (p + q = 1).
This principle also states p2 + q2 + 2pq = 1, where p^2 is the dominant homo-zygous allele, 2pq the heterozygous frequency and q^2 the recessive homo-zygous frequency.
In this case, 9 individuals represent 25% (q^2 = 0.25), thereby the feecuency of q is equal to √0.25 = 0.5.

Answer:
The universality of genetic code.
Explanation:
The DNA is a molecule made up from 4 different nucleotides (A, T, C or G). The sequence in which these nucleotides are ordered constitute a code that gives a cell instructions to produce a specific protein. This is called the genetic code.
Every three nucleotides code for a specific amino acid. For example, ACG codes for Arginine, CUC codes for Proline, and so on.
The genetic code is universal. This means that in all living organisms, a particular sequence of three nucleotides will code for the same amino acid. This property guarantees that the human gene that codes for human insulin will also code for human insulin in bacteria.
Answer:
FALSE
Explanation:
Blood actually enters the right atrium first and finally exits thru left ventricle to the body.
To go to lungs, it must go from right atrium to right ventricle to the lungs.
Answer:
Arp2/3 and formins differ in their mechanisms of actin polymerization
Explanation:
The actin cytoskeleton plays key roles in diverse cellular processes including, among others, morphogenesis and endocytosis. The Arp2/3 complex and formin family proteins are two different types of actin-binding proteins capable of modulating the dynamics of actin filaments. The Arp2/3 complex is well known to have a key role in spine morphogenesis by promoting the branching of existing actin filaments. On the other hand, formin proteins induce the formation of plasma membrane protrusions by promoting the formation of unbranched filaments.
Answer:
Let's analyze the graph.
we can see that in 1995, the total area occupied was around 8 he.
Then we have a steep increase, reaching a maximum in the year 1997, where the area occupied was 20 he.
After that the area decreases abruptly and remains (varying a little from year to year) around 5he
Now we can look at the year 2006, that year the area was around 5he, ut after that we can see an almost constant decrease in the area, where each year (except from 2010 to 2011) the area decreased.
Ending in 2014 near 1 or 2 hectares.
The conclusion that we can take from this graph is that, while some years ao the area fluctuated around some values, in recent years we can see a clear decrease in the area ocuppied by the Overwintering Monarchs.
