Sara read in a book that in 1800, the Italian physicist Alessandro Volta observed that two metals connected by a conducting liquid produced a continuous transfer of electrons. This phenomenon was different from the rapid static discharge observed by Benjamin Franklin.

Sara’s book was describing Volta’s observation of:

Answers

Answer 1

Answer:

the process described in the question, described by Alessandro Volta refers to superconductivity, in which two metals connected by a conductive liquid produce a continuous transfer of electrons, these metals are considered superconductors since they do not have electrical resistance and this is always maintained and when the temperature is adequate, different from terms such as the resistance that is the impediment to the flow passage, or to the electric static in which the energy accumulation is maintained without movement or transfer or the electric current that is the energy in the same metal.

Answer 2

Answer:

C) Electric current, which is the flow of electrons through a material.

Explanation:

You learned about the aptly named enzyme Citrate Synthase. There are more enzymes that count citrate as substrate or product. Compare and contrast two reactions below that each split two carbons from citrate to make oxaloacetate. One catalyzed by the enzyme ATP Citrate Lyase and the second catalyzed by Citrate Lyase.

Acetyl-CoA
Citrate → ↑ → Oxaloacetate lyase
CoA-SH → ↑ ↑ ←ATP ↓→ ADP + Pi
ATP Citrate
Acetate
Citrate → ↑ ↓→ Oxaloacetate
Citrate lyase

Which of the following is an accurate statement about why ATP is required by ATP Citrate Lyase?

a) The hydrolysis of the thioester involving CoA-SH helps split ATP into ADP and Pi.
b) The hydrolysis of ATP helps "pay for the formation of a thioester involving CoA-SH.
c) The Acetyl-CoA is pulled rapidly away to make lipids so the reaction needs extra energy to make it fast enough to keep up with demand.
d) The two carbons of acetate are more energetic than those on Acetyl-CoA and therefore don't need ATP to split them from citrate.
e) ATP is required to spit the two carbons from citrate.

Answers

Answer:

b) The hydrolysis of ATP helps "pay for the formation of a thioester involving CoA-SH.

Explanation:

In the citrate cycle, we know that lysis is mediated by the hydrolysis of ATP, which is the fuel of the reaction, so the correct answer is B. The hydrolysis of ATP helps "pay for the formation of a thioester involving CoA-SH.

What kind of research method is are these?
Hypothetical Study 1
Researchers recruited 50 young adults (ages 18-25) who had recently been diagnosed with Type 1 diabetes, 50 who had recently been diagnosed with Type 2 diabetes, as well as 50 non-diabetic young adults, ensuring a comparable distribution of age, race/ethnicity, and gender across samples. They asked all of these participants as well as the participants' parents to complete a self-report measure asking questions about the participant's dietary and exercise habits between ages 15 and the present. They also requested participants' medical records indicating their body weight over time. Researchers found that the group with Type 2 diabetes was significantly more likely to have been overweight than either of the other groups as early as age 15. They also reported significantly higher levels of unhealthy eating habits as well as significantly lower levels of physical activity across this whole time period. Young adults with Type 1 diabetes did not differ significantly from the non-diabetic group across any of these measures.
Hypothetical Study 2
Researchers recruited 100 obese college students to participate in a weight-loss study. Participants were randomly assigned to one of three groups. The first group participated in a didactic course teaching them about healthy eating habits, exercise, and other types of self-care. The second group received the same training and also participated in a weight-loss support group. The third group was placed on a waiting list to participate in the training until after completion of the study. Researchers found that students in both the group that received didactic training only and the group that received both didactic training and a support-group lost significantly more weight throughout the course of the study than did those in the wait-list control group, but that they did not differ significantly from each other. However, at 6-month follow-up, they found that 90% of those in the group that had only received didactic training had regained the weight they had lost, whereas only 50% of those in the group that had also participated in the support-group experienced similar weight gain.
Hypothetical Study 3
Researchers asked 100 high school students to complete weekly self-report measures over the course of a year, asking questions about sleeping habits as well as general health questions. They examined the relationship between the number of hours of sleep students got on average and the number of days they were ill throughout the year. Researchers found that students' average number of hours of sleep per night was inversely related to the average number of days they reported being ill throughout the year. However, students did not seem to experience additional health benefits by sleeping more than 8 hours per night.

Answer:

1. option B

2. option A

3. option D

Explanation:

1. Which of these studies is an experimental study?

Yes, you got it right, it is study 2. Study 1 and 3 are just observational studies, where researchers collect and interpret data based on what they have seen, heard or observed. But for the experimental design, there is a manipulation on the part of the researchers where he grouped them and administered treatments.

2. Study 1 employs a retrospective design.

You also got that part right, Study 1 actually employed the retrospective design by sampling individuals and then collecting information about their past which in this case is asking questions about the participant's dietary and exercise habits between ages 15 and the present and also their medical records.

3. Study 3 employs a prospective design

You also got this right. Study 3 actually employed the prospective design by sampling individuals and follow them over time and data about them is collected as their characteristics or situations changes and in this context, they observed even after a change by sleeping more than 8 hours per night, students still did not seem to experience additional health benefits.

a. allele frequency


b. gene pool


c. genotype


d. phenotype

Answers

Answer: option D.

Phenotype

Explanation:

Theory of natural selection shows that different organism survive, adapt and reproduce in their environment due to their different phenotypic variation. The phenotypic variation exist among individual organisms and it is heritable which is transfer from one generation to another.

Phenotype are traits or physical characteristics or observable characteristics of organism e.g organisms appearance, behavior e.t.c.

Answer:

d. phenotype

Explanation:

Natural selection exert pressure on the physical characteristics of organisms, that is, the phenotype.

Natural selection refers to the variation in the survival and reproduction of individuals within a population based on how adaptable they are to the environment in which they live.

The forces of natural selection act on the physical characteristics of individuals, that is how physically fit or unfit individuals are. Individuals that posses physical characters that makes them to be better adapted to the environment survives and reproduce better than their counterparts that are less adapted. Natural selection thus selects for the physical characters that make the individuals to be better adapted.

gene1: 0.01
gene2: 0.05
gene 3: 0.90
gene 4: 1.01
gene 5: 2.34

Which gene has a dN/dS ratio that provides the strongest evidence of negative (‘purifying’) selection?

Answers

Answer:

The correct option is gene 1 with the dN/dS ratio of 0.01

Explanation:

In order for negative selection to occur, the dN/dS ratio has to be between 0 and 1. There three genes that lie within this range, and hence, we can choose the smallest one to provide the strongest evidence among those to represented as the one being negatively selected. Where the dN/dS ratio is equal to 1, it means neutral and where the dN/dS ratio is greater than 1, it means positive selection.

What is phenotype?

Phenotype refers to the observable physical and behavioral characteristics of an organism, which are determined by the interaction between its genetic makeup (genotype) and the environment. The phenotype can include traits such as height, eye color, body shape, and even personality traits.

These characteristics are influenced by both genetic and environmental factors, such as exposure to sunlight, diet, and other environmental conditions. In many cases, a single gene may have multiple effects on the phenotype, and many genes may work together to produce a single trait. Phenotypic traits can also be influenced by epigenetic changes, which involve alterations in gene expression without changes to the underlying DNA sequence. Understanding the relationship between phenotype and genotype is crucial for fields such as medicine, agriculture, and genetics.
