Which of the following is not a step involved in critical thinking?

Researchers hypothesized that cocaine is pharmacologically active in primate fetal brain when pregnant primates are administered

pav-90 [236]

Answer:

Option A, Glucose metabolism in the fetal brain increased

Explanation:

Usage of cocaine during pregnancy is prohibited. However, in case if cocaine is taken it disrupts the metabolism as it increases brain glucose metabolism to the level of an adult human being. Since glucose metabolism in brain is a sensitive process, any disruption in it can lead to unaccounted effects such as dysfunctional circulation, and pharmacological effect. Cocaine increases the dopamine by blocking the dopamine transporters thereby increasing the Vmax. Since the brain of a child has all kind of neurochemical components, cocaine intakes by a pregnant woman produces reinforcing effects in brain of fetus and also make it pharmacologically active

Hence, option A is correct

In what ways do you think climate change will impact the water cycle

vampirchik [111]

Answer:Climate change intensifies this cycle because as air temperatures increase, more water evaporates into the air. Warmer air can hold more water vapor, which can lead to more intense rainstorms, causing major problems like extreme flooding in coastal communities around the world

Which plate is moving below the Pacific plate?

KiRa [710]

Answer:

The Pacific Plate is moving to the northwest at a speed of between 7 and 11 centimeters (cm) or ~3-4 inches a year. The North American plate is moving to the west-southwest at about 2.3 cm (~1 inch) per year driven by the spreading center that created the Atlantic Ocean, the Mid Atlantic Ridge.

Explanation:hope it works for you:)

Identify an example organism for each type of cellular respiration: aerobic respiration, anaerobic respiration, and fermentation

Julli [10]

Answer:

Anaerobic respiration-" The process by which cells that do not breathe oxygen liberate energy from fuel to power their life functions."

These organisms also use an electron transport chain to generate as much ATP as possible from their fuel, but their electron transport chains extract less energy than those of aerobic respiration because their electron acceptors are weaker. The Staphylococcus aureus and Lactococcus lactis are two organism which performs anaerobic respiration.

Aerobic respiration-"The process by which oxygen-breathing creatures turn fuel, such as fats and sugars, into energy."

Organisms who performs aerobic respiration:

Most of the living beings humans etc.

Fermentation:"The metabolic process by which organic molecules (normally glucose) are converted into acids, gases, or alcohol in the absence of oxygen or any electron transport chain."

Mechanism-" The main porpuse is to convert NADH back into the coenzyme NAD⁺ so that it can be used again for glycolysis."

During fermentation, an organic electron acceptor reacts with NADH to form NAD⁺, generating products such as carbon dioxide and ethanol or lactate in the process.

Types-

Ethanol fermentation,
Lactic acid fermentation.

Explanation:

Difference between Aerobic and anaerobic respiration:

In anaerobic cells, however, respiration typically takes place in the cell’s cytoplasm, since most anaerobic cells do not have specialized organelles.
In aerobic cells, the electron transport chain, and most of the chemical reactions of respiration, occur in the mitochondria.

Steps of Aerobic Respiration:

1. Glycolysis. In aerobic cells, the equation for glycolysis is:

Glucose + 2 HPO₄²⁻- + 2 ADP³⁻ + 2 NAD⁺ → 2 Pyruvate⁻ + 2 ATP⁴⁻-+ 2 NADH + 2 H⁺ + 2 H₂O,

2. Oxidative decarboxylation of pyruvate

2 (Pyruvate⁻ + Coenzyme A + NAD⁺ → Acetyl CoA + CO₂ + NADH),

3. Citric acid cycle

2 (Acetyl CoA + 3 NAD⁺ + FAD + GDP³⁻ + HPO₄²⁻ + 2H₂O → 2 CO₂ + 3 NADH + FADH₂ + GTP⁴⁻ + 2H⁺ + Coenzyme A),

4. Oxidative phosphorylation

34 (ADP³⁻ + HPO₄²⁻ + NADH + 1/2 O₂ + 2H+ → ATP⁴⁻ + NAD⁺ + 2 H₂O)

Electron Transport Chain Steps- These four complexes actively transfer electrons from an organic metabolite, such as glucose. When the metabolite breaks down, two electrons and a hydrogen ion are released and then picked up by the co-enzyme NAD+ to become NADH, releasing a hydrogen ion into the cytosol.

Complex I: The complex-structured proteins embedded in the phospho-lipid membrane.
Continuing onto Complex II,
Traversed to Complex III,
Cytochrome c via co-enzyme Q,
And then finally to Complex IV.

Note-By-products from other cycles and processes, like the citric acid cycle, amino acid oxidation, and fatty acid oxidation, are used in the electron transport chain. As seen in the overall redox reaction,

2 H+ + 2 e+ + ½ O₂ → H₂O + energy
