#carryonlearningWe respect Dr. Trudeau and all those earlier scientists who did the best they could within the contemporary understanding of the problem they addressed and utilizing the materials and technology they had at hand. Modern-day biologists like to talk about resistance/susceptibility genes and patterns of inheritance, rather than family blood. They think about infectious disease in terms of microbes and pathogenicity, rather than speaking of bad humors. They have identified vitamins and other nutrients that are abundant in some foodstuffs and lacking in other that are essential for optimal immune function. Without the benefit of such modern formulations, Dr. Trudeau, by a disciplined application of scientific curiosity and careful, clever methodology, shed light on each of these concerns, light that helped to illuminate the minds of scientists who came after. Still, a look at his original paper leaves us wondering, were the rabbits genetically identical? Probably not! Why? Were they all of the same sex and age? Couldn’t he have given the animals kept on short rations just a smaller amount of the same varieties of food available to the animals fed abundantly—after all, there might be some important nutrient missing in potatoes. In light of the title of the paper, why not measure bacterial numbers in the rabbits on post mortem rather than just survival time? (In a subsequent paper, he did exactly that.) Once you start critiquing an experiment from 100 years ago, or 10 years ago, or sometimes even last year, it’s hard to stop.
Can you think of anything else you would have changed about the Rabbit Island Experiment?

The first generation of hybrid offspring is called the ______ and can often be used to determine the ____ gene.
a. F2 generation; h.o.m.o.z.y.g.o.u.s.
b. F1 generation; h.o.m.o.z.y.g.o.u.s.
c. P generation; dominant
d. F1 generation; dominant
(Brainly needs to realize if they let us talk about college biology, that we are going to use words that have h.o.m.o. and that they are genuinely correct scientific terms.
The preferred generation of hybrid offspring is called the P generation and can often be used to determine the dominant gene.
What is P generation and dominant?
Dominant directs to the relationship between two versions of a gene. Then, Individuals receive two versions of each gene, which are called alleles, from each parent. When the alleles of a gene are different, So, one allele will be expressed This is a dominant gene.
When The P generation is the start of Mendel's work on inheritance, or receiving genetic qualities by transmission from parent to offspring. So, Basically that it refers to traits or genes that are passed from a parental generation to its offspring
When P is the parent gene, and also then the offspring goes to the F1 and also then F2, the dominant gene is what gene wins over a recessive. So the correct option is 'C'.

b) Explain why a leaf cannot be tested for starch by adding iodine solution directly.
Answer:
Due to presence of waxy layer.
Explanation:
A leaf cannot be tested for starch by adding iodine solution directly because waxy cuticle covering the leaves that prevents the penetration of iodine in the leave cells. First, the waxy layer should be removed by boiling the leaves that causes disruption in the cell membranes that make easier for the iodine to penetrate in the leave cells so that's why iodine can not be tested for starch directly.

Two women gave birth in the same hospital on the same afternoon. Their babies were taken
away, and then brought back to them one hour later. One of the women was worried that
she had been given the wrong baby. She asked for blood tests to be carried out. The hospital
found that she was group A and her husband was group O. The other mother was group
AB and her husband was group A. The woman with blood group A had been given the baby
with blood group O. The woman with group AB was given the baby with blood group B. Use
genetic diagrams to determine whether the women had been given the right babies.
Answer:
Explanation:
If the Husband of Woman One had group O blood, than It would be hard for Woman 2's baby to have group O blood, because the Parents of Baby 2 are AB and A. So the hospital did give the woman the right babies
Answer:
They were given the right baby cause the women who was worried her husband was group o and the baby they got was group o and the other women had a child with group b and her blood was a and b so yes it’s correct

Low-carbohydrate diets became popular in the late 1990s and were quickly proclaimed to be a fast and easy method of weight loss. The effectiveness and safety of these diets are dependent on the activity and overall health of the individual as well as the total nutritional content of the diet. However, it is true that in some cases, these diets have been effective. What metabolic effects caused by eating a low-carbohydrate diet can be linked directly to a decrease in fatty acid synthesis and an increase in fatty acid oxidation?
a. release of insulin from pancreatic's cells
b. dephosphorylation of AMPK
c. release of glucagon from pancreatic's cells
d. phosphorylation of AMPK
Answer:
c. release of glucagon from pancreatic's cells
d. phosphorylation of AMPK
Explanation:
Low-carbohydrate diets (LCDs) stimulate the secretion of glucagon by a decrease in the blood glucose concentration. Glucagon is a key hormone secreted by pancreatic cells in the same way as insulin but in an opposite way. This hormone (glucagon) prevents glucose accumulation as hepatic glycogen, while insulin helps to the accumulation of glucose in the liver as glycogen, thereby acting to reduce hepatic glucose output. Moreover, the AMP-activated protein kinase (AMPK) is a kinase protein that mediates the phosphorylation and inhibition of acetyl-CoA carboxylase (ACC) in order to reduce the synthesis of malonyl-CoA, a key molecule that regulates myocardial fatty acid oxidation.
