A woman who is heterzygous for familial hypercholesterolemia (F) marries a man who it also heterzygous for FH. They have three children, one of whom is homozygous dominant for the FH trait, one who is heterozygous, and one who is homozygous recessive for the F trait. What are the phenotypic outcomes for their children?
Numerous recent scientific studies indicate that environmental influences experienced by young adults can impact their offspring through a process called epigenetics. Explain how exposure to smoking cigarettes or consuming marijuana that contains the psychoactive substance THC could potentially influence the epigenetics of offspring
Are there organelles in Elodea not in onion skin? If so, what are they and why would you not expect them in the onion?What structures do the Elodea cells have that the red onion skin cells lack? They have chloroplasts because they need the chlorophyll to produce ATP energy from the sun (for food). Onions are underground and do not have access to the sun, so they lack chloroplasts.
What is a likely advantage of sexual reproduction. The advantages of sexual reproduction: produces genetic variation in the offspring. the species can adapt to new environments due to variation, which gives them a survival advantage. a disease is less likely to affect all the individuals in a population. The offspring of sexually reproducing organisms are all genetically unique. Because of this, sexually reproducing organisms may have more successful survival of offspring in environments that change than asexually reproducing organisms, whose offspring are all genetically identical.
In pea plants, round seed shape (R) is dominant to wrinkled seed shape (r) and yellow peas (Y) are dominant to green peas (y). What are the possible genotypes and phenotypes for a cross between RrYY and rrYy pea plants? How many squares does need to do a Punnett square analysis of this cross?
In pea plants, round peas (R) are dominant to wrinkled peas (r). a test cross between a pea plant with wrinkled peas (genotype rr) and a plant of unknown genotype that has round peas. going to end up with three plants, all which have round peas. From this data, can tell if the parent plant is homozygous dominant or heterozygous?
Explain how life is in the blood by using at least 5 biological key terms such as plasma, platelets, erythrocytes, and leukocytes as well as the composition of blood For the life of a creature is in the blood, and I have given it to you to make atonement for yourselves on the altar; it is the blood that makes atonement for one’s life. Therefore I say to the Israelites, “None of you may eat blood, nor may an alien living among you eat blood.”
Pacific coastal organisms are usually more robust than Atlantic species. There are several reasons for this great difference. One reason has to do with atmospheric circulation. The Hawawiian Green Sea Turtle, an endangered species, is just one animal who calls the Pacific Ocean home. The Pacific Ocean is the largest ocean in the world and occupies an area of 62.46 million square miles about a third of the earth’s surface area.
Case A Joy and Aiden have met with their GP as part of routine antenatal screening. Initial tests returned the results below. Please comment on their significance. Test Joy Aiden Patient history 23 y.o. female pregnant (6 WG) Caribbean ethnic group 25 y.o. male West African ethnic group RBC 4 x 10^12/L 5.7×10^12/L Hb 112 g/L 170 g/L MCV 93 fL 88 fL MCH 28 pg 30 pg MCHC 302 g/L 340 g/L HbS Solubility Negative Positive The family is referred to a genetic consultant. Upon meeting with the consultant, Aiden is asked about any genetic diseases running on his side of the family. Aiden shares he does not have genetic conditions but both his parents are carriers for Sickle Cell anaemia and has one sister who has the condition. The consultant also is interested in Joy’s family history. She shares that her parent are deceased and did not suffer from any apparent condition. Her brother and sister are healthy. However, her brother is carrier for sickle cell anaemia and has a daughter suffering from the condition. • What are common signs and symptoms of Sickle Cell Anaemia?
Meat tenderizer is often used to tenderize tough pieces of meat, like steak. Knowing that steak is made of protein-rich muscle tissue from cows, can you think of an explanation for how meat tenderizer works?This is certainly true when it comes to notoriously tough cuts of meat like beef brisket and pork shoulder. Cooking these cuts of meat slowly, either by braising, stewing or grill roasting, is the best way to get these tasty cuts of meat meltingly tender.
