All the offspring of a cross between a black-eyed mendelien and an orange-eyed mendelien have black eyes. What is the expected F2 phenotypic ratio of a cross between two F1 black-eyed mendeliens?
A) 1 black-eyed:1 orange-eyed
B) 3 black-eyed:1 orange-eyed
C) 1 black-eyed:3 orange-eyed
D) 1 black-eyed:0 orange-eyed
The phenotypic ratio of the cross is as follows: 3 red antennas: 1 white antenna
For question 2, the phenotypic ratio of the F2 generation is: 3 black-eyed: 1 orange-eyed
QUESTION 1
According to the first question, a gene coding for antenna color in butterflies is involved. Red antennas (“R”) is dominant to white antennas (“r”). Hence, a butterfly with genotype "Rr" will be phenotypically red.
According to this question, If both parents are heterozygous for red antennas i.e. Rr (red antenna) × Rr (red antenna), the following gametes will be produced: R and r. Using these gametes in a punnet square (see attached image), the following phenotypic ratio of offspring is produced:
3 RED ANTENNAS (RR, Rr, Rr) : 1 WHITE ANTENNA (rr)
2. In the second question, all the offspring of a cross between a black-eyed mendelien (BB) and an orange-eyed mendelien (bb) have black eyes (Bb). In a cross between two F1 black-eyed mendeliens i.e. Bb × Bb, the following proportion of offspring is produced:
BB, Bb, Bb, bb
Hence, a phenotypic ratio of 3 black-eyed: 1 orange-eyed

Lymph ______ are found throughout the body and are a signal of a disease, infection, or problem if they become and remain swollen for long periods of time.
______ are pathogens that cannot be killed with antibiotics because they are non-living. They take over cellular organelles to replicate and spread.
Because they are also eukaryotes with their own cell membranes and membrane-bound organelles, ______ are often difficult to combat with medicines.
A cell signal called ______ is produced by mast cells. These molecules cause more fluid to spread to an infected area.
_______ are the types of cells that produce antibodies.
All pathogens have unique identifying molecules on their surfaces called ______. Antibodies bind to these, and targeting the pathogen to be destroyed by the immune system.
______ 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.

The catabolic pathways that degrade fatty acids do not generate ATP directly, but produce NADH and acetyl-CoA.
a. True
b. False
Answer:
b.False
Explanation:
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.
What is a major role that fungi play in ecosystems
Answer:
Fungi play a crucial role in the balance of ecosystems. They colonize most habitats on earth, preferring dark, moist conditions. They can thrive in seemingly-hostile environments, such as the tundra. However, most members of the Kingdom Fungi grow on the forest floor where the dark and damp environment is rich in decaying debris from plants and animals. In these environments, fungi play a major role as decomposers and recyclers, making it possible for members of the other kingdoms to be supplied with nutrients and to live.

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.

The second generation of purebred cross of -hom-ozygo us recessive organism, with a —hom-ozygous dominant organism, contain a ratio of approximately _______ expressed dominant traits to recessive traits.
A. 2:1
B. 1:1
C. 1:3
D. 3:1
Answer:
D. 3:1
Explanation:
Gregor Mendel, in one of his numerous studies, performed a cross between purebred dominant (TT) pea plants and purebred recessive (tt) pea plants. All the offsprings of this cross appeared heterozygous tall (Tt) in the F1 generation.
However, when he self-crossed the F1 generation i.e. Tt × Tt, Mendel obtained a phenotypic ratio of 3 tall plants (dominant traits) : 1 short plant (recessive). This showed that the masked gene (recessive) was still present.

As you read in this chapter, fungi have long formed symbiotic associations with plants and with algae. How may these two types of associations lead to emergent properties in biological communities
Answer:
Fungi show symbiotic association with algae and plants. With plants, they thrive as endophytes in a form of the symbiotic association. This symbiotic association results in the emergence of novel characteristics in the world of biology.
The lichens function as a tool in finding the quality of air, as they grow in the environment containing good air quality. The tolerance towards heat is another characteristic. Some of the endophytes are witnessed in the plants, which grow in very hot conditions.
At such conditions, no fungi or plant can thrive, however, in the symbiotic association, they possess the tendency to thrive. If one tries to separate them, it results in the death of both.

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
15. Assuming the fluorescence threshold is set to be 1. Which gene has the highest gene expression rate? What is the Ct value? Gene with highest expression = ______________ Ct value = _______________
Answer:
The correct answer is - Gene 1 and 14.5 (or 14).
Explanation:
The cycle threshold is denoted as Ct value. It is the cross point at the threshold line meets with fluorescence signal reaction curve. In the given RTpcr experiment, the threshold line is fluorescence intensity 1 thus, Ct value for each gene will be the point at which each curve meets the fluorescence intensity line at 1. Ct value of is inversely proportional to amount of nucleic acid in the given sample.
Here, the Ct for gene 1 is the lowest, so the amount of DNA would be highest.
Gene with highest expression= Gene 1
Ct value= 14.5

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%.
