Know all STIS: pathophysiology, etiology, clinical manifestations, diagnostic tests, treatment, and complications. How is each transmitted during pregnancy to the fetus?
Know the different stages of syphilis; what organism causes each STI and is it viral, bacterial etc.?
Do you treat both partners and why?
What age group has the greatest risk of STIs and why?
What causes cervical cancer?
Answer and Explanation:
1. Each of the elements shown are transmitted to the fetus during pregnancy through the mother's bloodstream and through the umbilical cord, where the fetus receives all the support for its body, such as oxygen, nutrients, hormones, treatments, tests, among others. others. Some of them are possible through the visualization of the fetus and the manipulation of the products written by him.
2. Syphilis is a sexually transmitted infection caused by the bacteria Treponema pallidum. This infection has three phases (primary, secondary and tertiary) that are interspersed with asymptomatic periods, which aggravates the severity of the disease, since it presents itself as a silent evil. The primary phase occurs between 3-4 days after infection and its main symptom is the presence of wounds throughout the body, especially in the genitals. If not treated properly, 8 weeks later the secondary phase appears, where the infected person has red spots on the body, itching, fever, muscle pain and swollen and painful lymph nodes in the neck and armpit. When left untreated, the disease progresses to the tertiary stage where it presents severe symptoms that are difficult to diagnose. The disease affects the brain, eyes, heart, joints and the nervous system, causing severe headaches and even epilepsy.
3. It is necessary for both partners to be treated in case of any sexually transmitted infections. This must be done, primarily because the transmission occurred between these partners, which indicates that both have the disease and can reinfect themselves, or infect other people.
4. People aged 15 to 24 are at the greatest risk of being infected with a sexually transmitted infection. This is because people at this age are more likely to not get a steady partner and to adopt behaviors that facilitate infection such as having sexual contact without adequate protection.
5. What causes cervical cancer is the untreated infection of a virus called HPV. This type of cancer is usually asymptomatic, but in the early stages it may show bleeding from the genitals after sexual intercourse.

In which column on the chart below would the information below best fit for a mode of reproduction, CANNOT REPRODUCE WITHOUT A HOST?
Answer:
B. Virus.
Explanation:
Hello.
In this case, since bacteria (A.) reproduce via asexual reproduction via mitosis and the animal (D.) and vegetal (C.) cells could reproduce via sexual or asexual reproduction depending on the organism, they do not need a host to start the replication of the DNA and therefore reproduce. In such a way, it is widely known that viruses need a host that facilitates the replication of their DNA or RNA (depending on the virus) since they only have their genetic information but they do not have neither the RNA nor the DNA polymerase that favor such process, that is why they need a host.
Best regards.

Name the membrane transport process by which glucose moves from the extracellular fluid into cells.
Answer:
Facilitated diffusion
Answer:
HERE IS YOUR ANSWER
Explanation:
Facilitated diffusion is the diffusion process used for those substances that cannot cross the lipid bilayer due to their size and/or polarity (Figure 3.18). A common example of facilitated diffusion is the movement of glucose into the cell, where it is used to make ATP

Explanation:
You need to determine the sequence of a linear decapeptide. The following experiments have been performed:
1. Edman degradation generates 10 amino acids: Q, E, M, R, K, C, F, P, Y, A.
2. Cyanogen bromide (CNBr) cleavage gives two pentapeptides (5 aa’s).
3. Trypsin cleavage gives two tripeptides (AMR and QFK), and a tetrapeptide.
4. Chymotrypsin cleavage gives a dipeptide QF, a single amino acid, and a heptapeptide (7).
5. The C-terminal residue is identified as Cys using carboxypeptidase C, which removes amino acids from the C-terminal end of a polypeptide.
Give two possible sequences for the decapeptide, using aa three-letter codes.
Answer:
The two possible sequences for the decapeptide using a three-letter codes
are :

Explanation:
Natural selection is differential reproduction among individuals, in a population due to differences in phenotypes, which are said to be adaptive.
Individuals with the adaptive phenotype have a reproductive advantage (increased reproductive fitness); therefore, they contribute a disproportionately high number of progeny to the next genotype.
The adaptive genotype and the underlying mutation will increase in frequency in the generation over time.

A runner has a speed of 25 m/s. They see the finish line and speed up to 30 m/s. This happens in 5 seconds. If the runner has a mass of 75 kg, with what force did the runner cross the finish line? Show all work to receive full credit.
I know the answer is 75N but I don't know how to get 75N
Given parameters:
Initial velocity = 25m/s
Final velocity = 30m/s
Time = 5m/s
Mass of runner = 75kg
Unknown:
Force to finish the race = ?
Solution:
Force is defined as a pull or push on a body. According to Newton's first law, we can mathematically express force as the product of mass and acceleration;
Force = mass x acceleration
But we know that acceleration is the change in velocity with time, so;
Acceleration = [tex]\frac{Final velocity - Initial velocity}{time}[/tex]
So, force;
Force = mass x [tex]\frac{Final velocity - Initial velocity}{time}[/tex]
Input the parameters and solve;
Force = 75 x [tex]\frac{30 -25}{5}[/tex] = 75N
The runner crosses the line with a force of 75N

The Siamese cat breed has a light colored body and dark colored head, tail, and feet, all of which are called points. The Burmese cat breed has a dark colored body and points that are almost the same color as the body. Crossing Siamese with Burmese can produce the Tonkinese cat breed, which has coat and point color that is intermediate to the Siamese and Burmese parents.
In all three breeds, a temperature sensitive enzyme is responsible for the dark coloration of the points. However, it is active only at the extremes of the body where it is coolest. Select the statements that are true regarding the evidence of incomplete dominance and incomplete penetrance in these breeds.
a. Intermediate coat color in Tonkinese demonstrates incomplete dominance.
b. Development of points in Tonkinese demonstrates incomplete penetrance.
c. Light coat color in Siamese demonstrates incomplete penetrance.
d. Darker color at the extremes of the body in Tonkinese demonstrates incomplete dominance.
Answer:
Correct answer is A and B.
Explanation:
Because the Tonkinese breed has a coat that is intermediate to the coat color of the Siamese and Burmese, we can say that this demonstrates incomplete dominance which means that the dominant allele does not have the ability to completely mute the recessive allele in the phenotype.
This is also true because of the development points on the coat of the Tonkinese breed.
So the correct answer is A and B.

A genetic trait is inherited via the Y chromosome such that for a father with the trait, his male offspring have a 25% chance of inheriting it but his female offspring cannot inherit it. Suppose that in a certain population, 40% of offspring are male and offspring genders are independent events. For a father with the trait who has two offspring, what is the probability that the older offspring has the trait and the younger offspring does not?
Answer:
0.09
Explanation:
let us define these events as
O = older
Y = younger
Prob(O) = 40% offspring x 25% chance of inheritance
= 0.4x0.25
= 0.1
P(Y') = 40% offspring x (1-25%) +(1-40%)x1
= 0.4x0.75 + 0.6x1
= 0.3+0.6
= 0.9 this is the probability of having the trait.
Probability that older offspring has trait but younger does not have it
Prob(O n Y') = prob(O) x Prob(Y')
= 0.1x0.9
= 0.09
In rats, gene B produces black coat color if the genotype is B-, but black pigment is not produced if the genotype is bb. At an independent locus, gene D produces yellow pigment if the genotype is D-, but no pigment is produced when the genotype is dd. Production of both pigments results in brown coat color. If neither pigment is produced, coat color is cream. A third independently assorting gene involved in determination of coat color in rats is the C gene. At this locus, the genotype C- permits expression of pigment from genes B and D. The cc genotype, however, prevents expression of coat color and results in albino rats. For each of the following crosses, determine the expected phenotypes and their ratio in progeny:Part ABbDDCc x BbDdCcExpress your answer as five numbers separated by colons. If there is no progeny of a particular phenotype, enter zero (black:brown:yellow:cream:albino).Part BBBDdcc x BbddCcExpress your answer as five numbers separated by colons.
