Answer:
Man (dimples and freckles) - FfDd
Woman (no dimples and no freckles) - ffdd
Child (no dimples and no freckles) - ffdd
Explanation:
According to this question, the possession of freckles (F) and dimples (D) are the dominant traits. The union of a man with dimples and freckles and a woman with no dimples and freckles (ffdd) gave rise to a child that has no dimples or freckles (ffdd).
Since the child has a recessive 'ffdd' genotype, it means that the father will likely have a heterozygous genotype (FfDd). Therefore, the genotypes of the three persons involved are;
- Man (dimples and freckles) - FfDd
- Woman (no dimples and no freckles) - ffdd
- Child (no dimples and no freckles) - ffdd

Conjoined twins are two babies who are born physically connected to each other. Conjoined twins develop when an early embryo only partially separates to form two individuals. Although two fetuses will develop from this embryo, they will remain physically connected — most often at the chest, abdomen or pelvis.
Describe fluid exchange between capillaries and the interstitial fluid. Be sure to discuss the forces (pressure) that moves the fluid and the direction in which fluid moves. (4 points) In one to three sentences, describe the role of lymphatic system in this fluid exchange. (3 points) g
Answer:
Capillary exchange is the exchange of fluid from the capillaries into the interstitial fluid and vice versa. Diffusion, transcytosis, and bulk flow are three mechanisms that facilitate capillary exchange.
The blood plasma or interstitial fluid exerts a pressure of the fluid on the capillary walls known as Hydrostatic pressure. Osmotic pressure is a pressure exerted by proteins either in the blood plasma or interstitial fluid called oncotic pressure.
Lymphatic capillaries gather lymphatic fluid and regulate the pressure of interstitial fluid due to the forces of hydrostatic or oncotic pressure. An essential role of the lymphatic system is to return the fluid to the blood.

Scenario 1:
Genetic engineering can be used to create more productive strains of farm animals used for milk and meat production. By adding genes to an animal’s DNA, the animal can be made to be more resistant to common infections. This can reduce the need to administer large doses of antibiotics to the animals.
Do you think that this type of genetic engineering should be pursued? Explain your answer. (5 points)
What are some possible impacts (positive and negative) of this type of genetic engineering on individuals, society, and the environment? (5 points)
Scenario 2:
Mike was adopted, and his biological family history is unknown. Although he is healthy, he would like some understanding of his genetic makeup, including potential health risks and genes that he could pass on to his children. Mike has heard about commercial laboratories that can compare segments of your DNA to those of people with common hereditary diseases in order to give you some idea of how susceptible you are to the diseases. The results of these types of tests are highly inconclusive. If Mike’s DNA showed that he shares similarities in a segment of DNA with people who have a given disease, his chances of developing that disease or passing it on to his children may be slightly elevated, but they are not 100 percent. These tests can cost more than $2,500 and are not covered by many insurance companies.
Do you think that Mike should undergo the genetic tests? Explain your answer. (2 points)
What are potential pros and cons of having such tests done? (5 points)
Describe how the availability of these genetic tests might affect the frequency of genetic diseases in individuals and populations. (3 points)

How are human affiliative and aggressive behaviors different from what is seen in nonhuman primates? Provide specific examples.
Answer:
Humans are less aggressive as compared to non-human primates.
Explanation:
Human affiliative and aggressive behaviors are different from nonhuman primates because humans do more friendly and peaceful acts and are less aggressive in anger as compared to non-human primates which are less friendly and more aggressive in anger. Due to more aggressive behaviour of non-human primates causes more damaged to other animals and humans as compared to humans who is less damaging and aggressive.
What does the QRS complex represents as??
Answer:give me brainliest
Explanation:
A combination of the Q wave, R wave and S wave, the “QRS complex” represents ventricular depolarization. Ventricular depolarization occurs in part via an accessory pathway (AP) directly connecting the atrium and ventricle and thus capable of conducting electrical impulses into the ventricle bypassing the AV-His Purkinje conduction system.This term can be confusing, as not all ECG leads contain all three of these waves; yet a “QRS complex” is said to be present regardless.
Explanation:
QRS complex represents as ventricular depolarisation

1. In a parent pea plant with the allele pair Gg, what is the probability that one gamete will contain the G allele? Why?
2. In a parent pea plant with the allele pair GG, what is the probability that one gamete will contain the g allele? Why?
3. In a parent pea plant with the allele pair gg, what is the probability that one gamete will contain the g allele? Why?
Answer:
If the gamete will get either G or g, the probability will be 1/2 of getting G.
Explanation:
all question 3 answer is that. Because all 3 of question are same. only repeated three times
In a parent pea plant with the allele pair Gg, the probability that one gamete will contain the G allele is 0.5. This is because there are two possible outcomes in which one must definitely fall. So, it is 1/2.
What is Allele?Alleles may be characterized as the alternative form or versions of a gene that are responsible for particular traits in living organisms. They carry a code of genetic sequences within generations.
In a parent pea plant with the allele pair GG, the probability that the gamete will contain the g allele is zero. This is because there is no presence of allele g that can be determined within any gametes. So, it is not possible to get g in the pair allele of GG.
In a parent pea plant with the allele pair gg, the probability that one gamete will contain the g allele is 1 or 100%. This is because both carry g alleles. So, the probability is 100%.

A sample from a stock of a bacterial colony in liquid media was diluted by a factor of 106, and 2 ml of this dilution was spread on a Petri dish of solidified media. 56 colonies were observed. What was the concentration of bacteria of the initial stock?
Answer:
28 × 10⁶ colonies/ml
Explanation:
Let C be the concentration of bacterial in the initial stock. When it is diluted by a factor of 10⁶, the new concentration is C' = C/10⁶.
When 2 ml of this concentration is spread on a Petri dish of solidified media, 56 colonies were produced. The number of colonies, n after spreading the 2 ml of C' is C' × 2 ml = 2C' = 2C/10⁶.
So, n = 2C/10⁶.
Since the number of colonies after spreading on a Petri dish of solidified media is 56, n = 56 colonies.
So, 2C/10⁶ = 56
Making C subject of the formula, we have
C = 56 × 10⁶/2
C = 28 × 10⁶ colonies/ml
So, the initial concentration of bacteria is 28 × 10⁶ colonies/ml

For each of the following structures, first indicate its function in the fetus; then, note its fate (what happens to it or what it is converted to after birth).
a. Umbilical artery
b. Umbilical vein
c. Ductus venosus
d. Ductus arterious
e. Foramen ovale
Answer:
1. Functions:
a. Umbilical artery >> carries deoxygenated blood from the fetus to the placenta
b. Umbilical vein >> transports oxygenated blood from the placenta to the fetus
c. Ductus venosus >> allows oxygenated blood from the placenta to bypass the liver
d. Ductus arterious >> allows most of the blood from the right ventricle to bypass the fetus's non-functioning lungs
e. Foramen ovale >> oxygenated blood from the umbilical vein to bypass the pulmonary circulation
2. After the bird:
1. Umbilical artery >> medial umbilical ligament
2. Umbilical vein >> round ligament of the liver
3. Ductus venosus >> ligamentum venosum
4. Ductus arteriosus >> ligamentum arteriosum
5. Foramen ovale >> fossa ovalis
Explanation:
The umbilical artery is a paired artery localized in the abdominal and pelvic regions, which carries deoxygenated blood from the fetus to the placenta through the umbilical cord. The medial umbilical ligament is the obliterated part of the umbilical artery that arises from the internal iliac arteries. In utero, the umbilical arteries carry waste products back to the placenta, whereas the umbilical vein carries oxygenated blood from the placenta to the fetus. The round ligament of the liver (also known as ligamentum teres hepatis) is a remnant of the umbilical vein that exists in the embryonic stage, it connects the left lobe of the liver to the umbilicus. The ductus venosus is a slender shunt that allows oxygenated blood from the placenta to bypass the liver, it connects the intra-hepatic portion of the umbilical vein to the inferior vena cava. The ligamentum venosum is an extrahepatic, slender, and fibrous remnant of the fetal ductus venosus that travels between the left portal vein and the inferior vena cava. The ductus arteriosus is a fetal artery that connects the aorta to the pulmonary artery. The ligamentum arteriosum is a nonfunctional vestige of the ductus arteriosus, it is attached to the superior surface of the pulmonary trunk. The foramen ovale is an oval-shaped, small, opening in the wall (septum) between the two upper chambers of the heart. The fossa ovalis is a vestige stricture of the foramen ovale of the embryonic heart, which forms a depression in the right atrium of the heart.

______ is a non-specific response to disease, in which the body temperature rises
Answer:
nodes
Viruses
fungi
histamine
B-cells
antigens
Fever
When a paper cut breaks the skin, it introduces outside microorganisms into the cut. The body recognizes the break in the skin. Mast cells produce histamines, which cause more blood and lymph fluid to flow to the wound. This increased flow brings phagocytic white blood cells to the area, which destroy invading organisms until the blood can clot and the skin can heal over the cut, preventing more organisms from entering the body. If a cut is too deep or too wide, special care such as stitches and antibiotics could be needed to prevent infection.
