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.
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.
Without photosynthesis, life would not have been able to proliferate the way it had over the past several million years. Identify which single called organism made this possible
Answer:
This is the Photosynthetic Cyanobacteria. it was the ability of this unicellular organisms million of years ago, through photosynthesis; that lead to the emergence of separate singular organisms the plants. Plants constantly undergo photosynthesis as it absorbs CO2, and make use of sunlight to to produce carbohydrates for animals to survive. And this leads to the emergence of animals which feeds on the plants, and therefore re population of the Earth occurs.

How does a mutation get passed from parent to offspring?
Answer:
Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation. There are also nonhereditary mutations that occur in cells outside of the germ line, which are called somatic mutations.
Explanation:
on what characteristic of an organism does natural selection exert pressure?
a. allele frequency
b. gene pool
c. genotype
d. phenotype
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.

Answer:
Global warming
Explanation:
Global warming is defined as the heating of Earth's surface, atmosphere and oceans due to the result of human activity such as burning of fossil fuels that releases methane, carbon dioxide (CO2), and other greenhouse gases into the atmosphere.
Global warming is the result of action at one part of the world but it affects the other part of the world where human intervention is zero.
Due to global warming, there is extreme changes in climate which is resulting in melting of glaciers, rise in sea levels and loss of biodiversity.
Hence, the correct answer is Global warming.

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.
5. Florida boa constrictors are invasive top predators. How does the boa constrictor negatively impact species in the tertiary trophic level? *
It would not affect them
Tertiary consumers would increase.
Tertiary consumers would have less food
Tertiary consumers would decrease
Answer:
The correct answer is "Tertiary consumers would have less food".
Explanation:
Animals in the tertiary trophic level are omnivores that eat animals that are in the secondary trophic level because they are carnivorous as well. An invasive top predator such as boa constrictors not necessary eat animals in the tertiary trophic level, however they affect them because they eat their food. Boa constrictors' diet include a wide variety of animals, including birds, mammals, and other reptiles
Which consumer you think is a herbivore (eats plants only)?
Answer:primary consumers for ex sheep cows, etc...
Explanation:
These animals are consumers, don’t produce their own food, but get it only from the producers, like plants
One type of muscular dystrophy, Duchenne muscular dystrophy, is is an inherited condition that usually only affects boys. Muscle weakness is noticed as children begin to walk or run. Characteristic signs include walking on tiptoe and large calves. The disease occurs in one out of every 3000 newborn male children. Why is this disease limited to mostly boys?
Answer:
Explanation:
Duchenne muscular dystrophy acts as a X-linked recessive disease. Which means the gene sits on the X chromosome, and you need two bad copies to show disease (for females) and one bad copy (to show in males).
Now from our knowledge, we know males are XY and females are XX. Males have only one copy of the X chromosome from their mother and one copy of the Y chromosome from their father, thus if they get the mutated version of the gene that causes this disease, they will get the disease. However, if a female has a mutated version of gene on one of the X chromosome, the other X chromosome could have a normal gene and that normal gene would take over and produce a normal phenotype/function.
Since, boys only have one X chromosome, if they get the mutated gene they will get the disease, whereas females have two X chromosome (so even if one copy is bad and the other is good, the good version can take over, however boys don't have this) thus mostly male children are affected by this.

Fossil evidence shows that vertebrates made the transition from water to land during the period.
Answer:
Devonian period
Explanation:
The currently available fossil evidence showed that vertebrates made the transition from water to land during the Devonian period. Specifically, the migration happened in the late Devonian period.
One of the features that enabled migration from water to land is the development of legs as against fins. While the latter is useful for movement in water, the former is necessary for locomotion on land.
In the late Devonian period, the first group of vertebrates with legs emerged. The tetrapods or four-legged vertebrates were known to have emerged about 330 million years ago and consist of the amphibians, reptiles, and mammals.

Which of the following statements is incorrect?
1. The tracheal mucosa consists of pseudostratified ciliated columnar epithelium.
2 .The trachealis muscle and elastic connective tissue allow for changes in the diameter of the trachea.
3. The trachea is located posterior to the esophagus and extends from the larynx to the superior border of the fifth thoracic vertebra.
4. The trachea has incomplete hyaline cartilage rings.
Answer:
The trachea is located posterior to the esophagus and extends from the larynx to the superior border of the fifth thoracic vertebra.
Explanation:
This is a wrong statement. Anatomically ,this organ of upper respiratory system is located anterior to the oesophagus.Thus it is the oesophagus that is located posterior to the trachea.
It passes through the posterior mediastanium to branch into the left and right main bronchi.
it bends towards it ends to the right,which results in the crossing of the left main bronchus anteriorly to the oesophagus.
It is lined by mucus gland produced by pseudo stratified columnar cells and some ciliated and non ciliated cells.
The mucus helps in warming up inhaled air and filtration of the air of dust particles.
In a garden plot, you count 50 tall plants and 50 short plants. All the plants are offspring of the same two parent plants. What is the ratio of tall to short plants?
Answer:
50 to 50
Explanation:
Let me know if it’s right
The ratio of tall to short plants is 1:1 or 50 tall plants to 50 short plants. The ratio is expressed as 1:1 because the number of tall plants and short plants are equal.
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.
