Cite particularly the difference in the synthesis of the two biomolecules in animals and plants.
Answer:
The preceding section reviewed the major metabolic reactions by which the cell obtains and stores energy in the form of ATP. This metabolic energy is then used to accomplish various tasks, including the synthesis of macromolecules and other cell constituents. Thus, energy derived from the breakdown of organic molecules (catabolism) is used to drive the synthesis of other required components of the cell. Most catabolic pathways involve the oxidation of organic molecules coupled to the generation of both energy (ATP) and reducing power (NADH). In contrast, biosynthetic (anabolic) pathways generally involve the use of both ATP and reducing power (usually in the form of NADPH) for the production of new organic compounds. One major biosynthetic pathway, the synthesis of carbohydrates from CO2 and H2O during the dark reactions of photosynthesis, was discussed in the preceding section. Additional pathways leading to the biosynthesis of major cellular constituents (carbohydrates, lipids, proteins, and nucleic acids) are reviewed in the sections that follow.

Carbohydrates
In addition to being obtained directly from food or generated by photosynthesis, glucose can be synthesized from other organic molecules. In animal cells, glucose synthesis (gluconeogenesis) usually starts with lactate (produced by anaerobic glycolysis), amino acids (derived from the breakdown of proteins), or glycerol (produced by the breakdown of lipids). Plants (but not animals) are also able to synthesize glucose from fatty acids—a process that is particularly important during the germination of seeds, when energy stored as fats must be converted to carbohydrates to support growth of the plant. In both animal and plant cells, simple sugars are polymerized and stored as polysaccharides.
Gluconeogenesis involves the conversion of pyruvate to glucose—essentially the reverse of glycolysis. However, as discussed earlier, the glycolytic conversion of glucose to pyruvate is an energy-yielding pathway, generating two molecules each of ATP and NADH. Although some reactions of glycolysis are readily reversible, others will proceed only in the direction of glucose breakdown, because they are associated with a large decrease in free energy. These energetically favorable reactions of glycolysis are bypassed during gluconeogenesis by other reactions (catalyzed by different enzymes) that are coupled to the expenditure of ATP and NADH in order to drive them in the direction of glucose synthesis. Overall, the generation of glucose from two molecules of pyruvate requires four molecules of ATP, two of GTP, and two of NADH. This process is considerably more costly than the simple reversal of glycolysis (which would require two molecules of ATP and two of NADH), illustrating the additional energy required to drive the pathway in the direction of biosynthesis.

Think about the podcast that you listened to in the Lesson 2.01 Introduction. Write a one-paragraph (using complete sentences) description of the experiment that was performed on these two women. Be sure to include the following: Why was the experiment conducted? What was done to the two women in order to conduct the experiment? What conclusions could be made from this experiment? Why do you think that experiments like this are no longer performed?
Explanation:
The experiment was conducted with the purpose of understanding what makes us "who we really are"; our environment or genetics?
The two women, Paula Bernstein and Elyse Schein identical twins were separated from each other at birth and only got to be reunited when they turned age 35.
"It's undeniable that genetics play a huge role," says Paula. This makes us concludes that genetics still play a role in determining who really are.
Such experiments are no longer performed today because there are legal restrictions put in place against such actions, including the ethical issues it created.

Note: The question is incomplete. The complete question is found in the attachment below.
Explanation:
High temperatures or changes in pH can denature an enzyme, causing it to lose its shape and activity.
Enzymes speed up chemical reactions by lowering the activation energy which allows the reaction to proceed much more quickly.
An enzyme is considered a(n) catalyst because it speeds up a chemical reaction without being used up.
The induced fit between an active site and its substrate often strains bonds and helps the reaction proceed.
A(n) inhibitor is a molecule that can bind to an enzyme and prevent the enzyme from working.
During an enzymatic reaction, a molecule of substrate binds to the enzyme and is broken down into one or more molecules of product which are released.
The specific location within an enzyme molecule where the substrate binds is called the active site.
Lactose takes years to break down on its own. But if exposed to the protein lactase, the reaction proceeds very quickly, while lactase itself remains unchanged. Lactase is an example of a(n) enzyme.

Killer whales, also known as orcas, hunt and eat numerous other organisms — more than 140 species. However, orcas themselves are not hunted by any other organism. In other words, they are at the top of the food chain.
Group of answer choices
Mutualism
Parasitism
Commensalism
Competition
Predator-Prey
hi :)
The relationship described is predator-prey.
The orca is hunting and eating other organisms, which is known as a predator-prey relationship.
In case you need help with any more of these-
Mutualism is when both animals get something out of the relationship, for example, some kinds of shrimp get the food out of fishes teeth. The fish gets clean teeth, and the shrimp gets a meal.
Parasitism is fairly self-explanatory. This is when a parasite lives and gains from a host, while the host is harmed and could get diseases from the parasite.
Commensalism is when one animal benefits and the other isnt harmed nor benefited. An example of this is the remora fish which clings to the bottom of other fish when it gets tired.
Lastly, Competition. This is when two organisms compete for something they need to survive. For example, two lions could compete for a food source, such as a zebra. Usually, the strongest and fastest organism survives, or wins.

What is true about cardiac (heart) cells compared to brain cells?
Different DNA which make different proteins
Same proteins being used to create different DNA
Same DNA being used to make different proteins
Different proteins used to create different DNA
Answer:
Same DNA being used to make different proteins
Explanation:
Cells of all living organisms contain the genetic material called DNA. One of the characteristics of multicellular cells is the ability of their cell to DIFFERENTIATE i.e. form specialized cells during division.
However, it is worthy to note that all cells possess the same DNA but some of the genes contained are expressed into proteins while others are not. This leads to why cells that contain similar DNA make different proteins and perform differently.
In this case, cardiac (heart) cells and brain cells contain the same DNA but due to the expression of some genes and repression of others, they are able to differentiate into different cells.
Explain whether an experiment or an observational study would be more appropriate to investigate whether meditation is effective in lowering blood pressure.
Answer:
Experiment.
Explanation:
An experiment would be more appropriate method to investigate whether meditation is effective in lowering blood pressure because experiment has a control group as well as a testable group. Due to control group and testable group, we can easily find out the effect of meditation in lowering blood pressure if we apply meditation techniques to the testable group and compared it with the control group, we get results.
Describe the nervous response pathway when you taste something bad and spit it out. Using these keywords: stimulus, chemical receptor, sensory neurone, relay neurone, motor neurone, muscles, response, electrical impulse, chemicals
Answer: Nervous system includes the brain which is the main center for interpreting various stimuli in the environment.
Explanation:
The nervous system detects the food stimulus. The chemical receptors present in the tongue detects the chemicals present in the food. These receptors send the impulses to the sensory neuron present in the brain. The impulse is then transmitted to the relay neuron then to motor neuron and then finally to the muscles of the mouth. The muscles of the mouth help in spitting the food as the sensory neurons help in detecting the taste of the food and find it either edible or non-edible.
The respiratory rate times the tidal volume corrected for the dead air space in the lungs is the __________.
a. vital capacity
b. respiratory minute volume
c. pulmonary ventilation rate
d. alveolar ventilation rate
e. external respiration rate
Answer:
d. alveolar ventilation rate
Explanation:
Alveolar Ventilation rate (AVR) refers to the rate of airflow that reaches the alveoli which is available for gas exchange with the blood in a given unit of time. AVR is generally calculated as the amount in millimeters of air expired that equilibrates (i.e., exchanges) with alveolar gas per min unit (ml/min). AVR is affected by breathing frequency, tidal volume ( i.e., the normal amount of air between inhalation and exhalation), and the amount of dead space in the lungs.

What is the role of carbon storage in organisms?? Plz answer fast in paragraph form if possible
Biological carbon storage happens when the carbon is stored in natural environment in animals and plants. This process includes what are known as carbon sinks, such as forests, grasslands, oceans, and other bodies of water.
What is Carbon storage?Carbon capture and storage is an attempt to remove the carbon dioxide gas from atmosphere after burning gas, oil, coal, or biomass before it actually enters the atmosphere, and to store it in the environment in various forms. Carbon storage has a success rate of between 50% to 68% of captured carbon, while aspirations of a 90% or 100% capture rate have not been achieved properly.
Carbon storage is carbon which is not emitted into the atmosphere. Less amount of carbon in the atmosphere will reduce the greenhouse gas effect and thus also lessens the impact of climate change and global warming.

In the fourth century BC, Aristotle observed a phenomenon in which he saw a circular shadow on the Moon. He argued that Earth was a sphere based on this observation. What phenomenon caused the shadow on the Moon? *
a solar eclipse
a lunar eclipse
a spring equinox
a summer solstice
Answer:
a lunar eclipse
Explanation:
The shadow that Aristotle saw was caused by a lunar eclipse. At that time the sun, earth, and the moon nearly straight alignment caused the Earth's shadow to be reflected on the moon. This shadow is what ultimately led Aristotle to believe that the Earth was a sphere. This should not be confused with a solar eclipse which is similar but instead the sun, moon, and earth align in that order which causes the moon to completely block the sun to anyone on earth.

What is phagocytosis in regard to the immune system of humans?
Answer:
Phagocytosis is the process of introducing larger particles into a larger cell. The process takes place by twisting the cell membrane of the "host" and enveloping the particles with a phagocytic bubble. Leukocytes use phagocytosis to take in and incapacitate bacteria that enter our body, so phagocytosis plays an important role in the immune system, as it prevents harmful cells from affecting humans.

Oxygen:
Carbon Dioxide:
Sugar:
Urea:
Answer:
Explanation:
in the given sample of blood concentration of all the comonents is normal. the concentration of urea is 2.6 to 6.5 mM, concentration of carbon dioxide is 23-29 meq/L, while concentration of glucose ad oxygen are 0.9 g and 20.1 ml respectively.
Blood is the component of the circulatory system which is essential for the transport of gases and excretion of waste products. It is crucial for nutrient and oxygen supply to the body.
The concentration of oxygen was 95.6 mmHg, carbon dioxide 39.3 mmHg, Sugar 115.5 mg and urea 13 mg.
The vital substance of blood can be explained as:Red blood cells are called erythrocytes that are responsible for oxygen transportation through the hemoglobin component to the body parts while on their way back it carries the carbon dioxide.Sugar is the major form of energy needed by the body for functioning which enters the blood from the liver.Urea is the waste complement removed with the help of blood collected from the liver and excreted by kidneys.Therefore, the normal concentration of blood substances is oxygen 95.6 mmHg, carbon dioxide 39.3 mmHg, Sugar 115.5 mg and urea 13 mg.

Mutations result in changes to genotype that can result in changes in phenotype. Explain how a mutation causes a change in the genotype of an organism AND may result in a change in the phenotype of an organism.
Answer:
A mutation can alter the structure/function of a particular protein, thereby also altering the phenotype resulting from this new variant
Explanation:
A mutation can be defined as a genetic change in the genome of an organism. Some mutations are capable of modifying the expression and/or structure of the proteins, while other mutations (known as silent mutations) have no effect on the resulting proteins. When mutations occur within the gene region encoding a protein (i.e., exons), they are potentially capable of producing a faulty protein. For example, a mutation can alter the Open Reading Frame (ORF) of the resulting protein, thereby inactivating it. The mutations that alter the structure and/or function of the protein can also alter the resulting phenotype associated with the expression of this protein. For example, a mutation within a gene that encodes a key enzyme can potentially alter the binding site of the protein, so the resulting mutated enzyme cannot bind to the substrate anymore. In consequence, this mutation alters the phenotype of the individual who is not more able to carry out the metabolic reaction catalyzed by the faulty enzyme.
