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.

What are the mechanism that use to resist the antimicrobial agents?There has been several mechanisms, like resistance to antimicrobial agents, encapsulation or secretation of proteins that affects and might destroy the phagocyte along with some leukocytes in our body perform phagocytosis as a defense mechanism against the pathogenic bacterium.
These phagocytes contain lysosomes, intracellular granules that possess bactericidal substances. When the phagocyte ingests the pathogen, a phagosome is formed, which merges with the lysosome, forming the phagolysosome, which is where toxic substances and enzymes kill the ingested microorganism.
There are several mechanisms by which a microorganism can survive this process as resistance to antimicrobial agents. Some bacteria use phenolic glycolipids from their cell wall, to eliminate toxic oxygen compounds.
Therefore, You can get infected with hand, foot, and mouth disease if you have the virus on your hands and then touch your eyes, nose, or mouth.

Why can viruses not fit in any domain? How are they different from all other forms of Life? What would need to occur for viruses to be classified as "alive"?
Answer:
virus are obligate parasites. Viruses do not, however, carry out metabolic processes. Most notably, viruses differ from living organisms in that they cannot generate ATP.
Gene X always produces the same mRNA (one splice form) and the same protein in all cells in which it is expressed. The same amounts of gene X mRNA and protein are present in brain, kidney, and heart cells. However, the activity associated with the protein is present only in the heart. Which of the following are possible explanations?
a. A splicing factor necessary for removing all of the primary transcript's introns is present only in the heart.
b. A splicing factor necessary for removing all of the primary transcript's introns is present only in the brain and kidney.
c. Protein X is phosphorylated only in the heart.
d. Protein X is phosphorylated only in the brain and kidney.
There are two explanations for this phenomenon: phosphorylation of the protein X in the heart activates its function (Option C) or phosphorylation of the protein X in the kidney and the brain deactivates its function (Option D). Therefore, both Option C and Option D are correct.
Phosphorylation is a posttranslational protein modification that is capable of activating or deactivating protein function.
Phosphorylation alters the three-dimensional structure of a protein, thereby modifying its function (i.e., activate or deactivate the target protein).
Phosphorylation occurs at specific amino acids (e.g., serine and threonine residues) of the target protein.
Moreover, mRNA splicing (RNA processing) occurs before the protein state, it is a transcriptional process. This process consists in removing the non-coding regions or 'introns' from pre-mRNA and subsequent joining protein-coding regions or 'exons' to enable the translation of the mRNA into a protein.
In consequence, in this case, it is possible that 1-phosphorylation of the protein X in the heart activates its function, or 2-phosphorylation of the protein X in the kidney and the brain deactivates its function. Therefore, both Option C and Option D are correct.

Mr. L was walking through the woods wearing shorts and sandals. He noticed a small tick on his ankle the same evening, and several weeks later he developed flu-like symptoms. A sample of his blood revealed the presence of long, wavelike cells that were twisting and waving. Based on the microscopic findings, which type of microorganism is responsible for Mr. L's symptoms
Answer:
Protozoa
Explanation:
The long, wavelike cells seen under the microscope would most likely be protozoa and the microorganism responsible for Mr. L's symptoms.
Tick as a vector is capable of causing diseases such as lyme disease, anaplasmosis, babesiosis, Powassan virus disease, tularemia, and a host of other diseases. Among all the diseases, babesiosis is particularly caused by a protozoan known as Babesia microti and it elicits malaria-like symptoms in individuals. Most of the other diseases are caused by bacteria pathogens while a few are caused by virus.
Apart from the above, the morphological characterization of the microorganism responsible for Mr. L's disease is typical for protozoans. Many of them are long and flagellated with a wave-like motion as a movement.
Hence, the case of Mr. L would be that of protozoa.

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.

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.
