Answer: B

Explanation: Managing emotions is actually healthy, being able to control how you feel about a certain topic will make life much easier. Practicing this will only help in the future. Suppressing emotions will only stress you out more. Giving into emotions is obviously going in the wrong direction, don't give up.

D. Explain the relationship between the pulse recorded in the finger and heart muscle contraction ______________________________

Setler [38]

Answer:

D. Heart contraction and pulse are connected with one another.

E. Atrial diastole and ventricle diastole.

Explanation:

Heart construction and pulse of an individual are connected as one can hear the pulse every time contraction of the heart is completed. Pulse can be understood by this that it represents the number of the contractions is completed by heart each time.

In the pulse tracing, there are two parts of the heart that are discernible which represents the contraction of the heart that are Atrial diastole and ventricle diastole.

Considering the same population of cats as in Part A, what is the expected frequency of each genotype (TLTL, TLTS, TSTS ) based

zaharov [31]

Answer:

P = f(TLTL) = 0,16

H = f(TLTS) = 0,48

Q = f(TSTS) = 0,36

Explanation:

Hello!

The allele proportion of any locus defines the genetic constitution of a population. Its sum is 1 and its values can vary between 0 (absent allele) and 1 (fixed allele).

The calculation of allelic frequencies of a population is made taking into account that homozygotes have two identical alleles and heterozygotes have two different alleles.

In this case, let's say:

f(TL) = p

f(TS) = q

p + q = 1

Considering the genotypes TLTL, TLTS, TSTS, and the allele frequencies:

TL= 0,4

TS= 0,6

Genotypic frequency is the relative proportion of genotypes in a population for the locus in question, that is, the number of times the genotype appears in a population.

P = f(TLTL)

H = f(TLTS)

Q = f(TSTS)

Also P + H + Q = 1

And using the equation for Hardy-Weinberg equilibrium, the genotypic frequencies of equilibrium are given by the development of the binomial:

$p^{2} = f(TLTL)$

$2pq = f(TSTL)$

$q^{2} = f(TSTS)$

So, if the population is in balance:

$P = p^{2}$

$H = 2pq$

$Q = q^{2}$

Replacing the given values of allele frecuencies in each equiation you can calculate the expected frequency of each genotype for the next generation as:

$f(TLTL) = P = p^{2} = 0,4^{2} = 0,16$
