Is there a correlation between heart rate and blood pressure?

1 answer:

6 0

While your heart rate increases, your blood pressure doesn't. When you have an increased heart rate your heart is doing more beats a minute dilating your vessels to allow more blood flow. Blood pressure is measured in two ways, systolic pressure and dystolic pressure. (120/80)

Which pair is mismatched? Multiple Choice Trypanosoma - causes African sleeping sickness Giardia - transmitted by feces in drink

Grace [21]

Answer:

Trypanosoma ------------ causes Chagas disease.

Trypanosoma -------------- causes African sleeping sickness.

Giardia --------------------- transmitted by feces in drinking water.

Trichomonas ------------ sexually transmitted.

Histoplasma ------------- causes Ohio Valley fever.

Explanation:

- Trypanosoma cruzi is a parasite transmitted by the bite of an insect of the Triatominae subfamily, very common in rural areas. It causes weakening of the heart muscle and heart failure, characteristic of Chagas disease.

- Trypanosoma brucei is a hemoparasite - found in the blood - transmitted by the tse-tse fly. Causes African trypanosomiasis or African sleeping sickness, characterized by progressive involvement of the central nervous system.

- Giardia lamblia is a parasite that is predominantly found in the duodenum. Infestation by this biological agent produces abdominal pain, nausea and belching with an unpleasant taste. It is transmitted by water contaminated with feces.

- Trichomonas vaginalis is a parasite that is transmitted through sexual contact, and produces vaginal trichomoniasis, a disease that causes inflammation and secretion in the genitals of men and women.

- Histoplasma capsulatum is a fungus that produces the disease called Ohio Valley fever (histoplasmosis), characterized by cough with expectoration, respiratory distress, fever, headache and severe muscle aches.

in the experiment determining the parental genotype of fruit flies from a monohybrid cross, if the number of long wing offspring

Dmitry_Shevchenko [17]

parental genotype of fruit fly Long wing: short wing would be 1 : 1

In monohybrid cross the number of short wing will be equal to number of long wing

Alternate forms of the same gene are called allele
the two alleles for a particular gene are identical the gene pair is homozygous
If an individual is homozygous for a particular trait then each parent contributed the same allele for that trait.
If an individual is heterozygous for a particular trait then each parent contributed a different allele for that trait.
The probability of obtaining a dominant phenotype from self-fertilization of a heterozygous individual is 3/4.

1. a) father (Rr), mother (rr)

b) from the attached file(1)

c) the possible genotypes are

Rr - 50%
rr - 50%

d) but from the information given above the only possible genotype for SpongeGerdy is Rr, because we were told that she was squarepants

e) Rr

f) from the attached file(2)

g) the possible genotypes are

RR - 25%
Rr - 50%
rr - 25%

h) the genotypes for squarepants are RR and Rr

therefore probability is (25 + 50)% = 75% or 3/4

i) the only genotype for roundpants is rr

therefore probability is 25% or 1/4

2. a) wilba - Ee , wilbur -EE

b) from the attached file(3)

c) the possible genotypes are

EE - 50%
Ee - 50%

d) the genotypes for round eye are EE and Ee

therefore probability is (50 + 50)% = 100% or 1

e) the only genotype for oval eye is ee

therefore probability is 0

3. a) squidward - BB . squidette - bb

b) from the attached file(4)

c) the only possible gene is Bb - 100% or 1

d) the genotypes for a light blue skin are BB and Bb

therefore probability is (0 + 100)% = 100% or 1

e) the only genotype for a light green skin is bb

therefore probability is 0

f) No, they are not. this is because they are heterozygous i.e.( they carry gene for a light green skin)

g) from the attached file(5)

h) the possible genotypes are

BB - 25%
Bb - 50%
bb - 25%

i) the genotypes for a light blue skin are BB and Bb

therefore probability is (25 + 50)% = 75% or 3/4

j) the only genotype for a light green skin is bb

therefore probability is 25% or 1/4
