Imagine that you are a hungry cell and find a large supply of citrate (citric acid). how many atps can you get from each citrate molecule if you use both the citric acid cycle and the electron transport chain?
Each citrate molecule can generate 6 ATPs through the citric acid cycle and the electron transport chain.
Explanation:
The citric acid cycle and the electron transport chain work together to produce ATP from citrate molecules. Each citrate molecule can produce one ATP in the citric acid cycle. In addition, the citric acid cycle generates three NADH and one FADH₂ per citrate molecule. These NADH and FADH₂ molecules enter the electron transport chain, where each NADH can produce as many as three ATP, and each FADH₂ can produce as many as two ATP. Therefore, the total number of ATP molecules that can be generated from each citrate molecule using both the citric acid cycle and the electron transport chain is:
1 ATP (from the citric acid cycle) + 3 ATP (from NADH) + 2 ATP (from FADH₂) = 6 ATP per citrate molecule
An allele is one of the alternative forms of a gene that governs a trait. If a fern plant is heterozygous for a particular trait, how can the alleles that control that trait be described? A. one dominant, one recessive B. two dominant C. three recessive, one dominant D. two recessive
Answer:
The correct answer is A. one dominant, one recessive
Explanation:
A gene can have many alternative forms called alleles. These alleles can be present in homozygous condition or heterozygous condition. In homozygous condition chromosome contains two same forms of an allele of a gene. In heterozygous condition a chromosome contains two different forms of an allele of a gene.
These alleles can be dominant or recessive. A dominant allele can be expressed in both homozygous and heterozygous condition, but a recessive allele will only express in homozygous condition.
So If a fern plant is heterozygous for a particular trait then it contains one dominant and one recessive allele because in heterozygous condition two different forms of allele is present. Therefore the right answer is A.

Diffusion always causes particles to move from a region of
Diffusion is the process in which particles move from an area of high concentration to an area of low concentration until a uniform concentration, known as dynamic equilibrium, is reached.
Explanation:Diffusion is the process through which particles in a gas, liquid, or solid spread out, or diffuse, from regions of high concentration to regions of lower concentration. This mechanism is driven by the kinetic energy from the thermal motion of particles resulting in the spreading until a dynamic equilibrium is reached. Therefore, diffusion causes particles to move from a region of higher concentration to a region of lower concentration.
This process continues until the concentration becomes equal throughout the medium, a condition known as dynamic equilibrium. At equilibrium, the particles continue to move, but there is no net transfer of molecules because the rates of movement between the regions are equal.
Several factors affect the rate of diffusion, including the mass of the molecules, the environment, and the amount of thermal energy they possess, which is a function of temperature. Ultimately, however, diffusion is driven by the principle of concentration gradient, which ensures that molecules constantly move from high-concentration areas to lower ones.

Why can’t an animal last without water and food for a long time
Animals need water for crucial cellular processes and to prevent drying out. They require food to generate energy, maintain stable internal environment or homeostasis, and keep up body functions. While certain animals store fat for energy during food scarcity, regular intake of food and water is vital for survival.
Explanation:Animals cannot last without food and water for long due to several biological reasons. Water is critical for cellular processes, and if an animal is exposed to air, their bodies tend to lose water and risk of drying out. Biological adaptations help animals retain water, but they cannot survive without replenishing lost water for long.
Moreover, animals need food to maintain homeostasis, the ability to maintain a stable internal environment amidst external changes. Food provides the energy required for various body functions, including maintaining body temperature. Therefore, without regular intake of food, animals cannot sustain energy, and their vital functions start to fail, leading to survival risk.
Certain animals need excess body fat for insulation and energy storage during scarce food availability. However, periodical replenishment, either by eating or fat storage used for energy, is critical for survival on land.

Investigate what newborn babies, skunk cabbage, hibernating bears, and a banned diet drug called dnp all have in common with regards to cellular respiration.
Final answer:
Newborn babies, skunk cabbage, hibernating bears, and DNP all reveal unique interactions with cellular respiration, relating to temperature regulation or metabolic rate variance.
Explanation:
Newborn babies, skunk cabbage, hibernating bears, and a banned diet drug called DNP all showcase unique aspects of cellular respiration. Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.
Bears during hibernation slow down their metabolism and lower both heart rate and body temperature, thereby conserving energy. Newborn babies, especially preterm ones, might experience a condition known as non-shivering thermogenesis where they produce heat through metabolic processes due to their inability to shiver efficiently. Skunk cabbage can generate heat to help spread its scent and melt surrounding snow, a process known as thermogenesis. Lastly, the drug DNP interferes with the proton gradient in mitochondria, leading to an increase in metabolic rate and production of heat, which is why it was used as a weight loss aid before being banned due to toxicity. All these examples reflect on the diverse roles and behaviors of organisms or substances related to cellular respiration.

according to Charles Darwin what biological mechanism
According to Charles Darwin, the biological mechanism that drives evolutionary change is natural selection. This is a process by which individuals with favorable traits are more likely to survive and reproduce, leading to the accumulation of beneficial traits over time.
Explanation:According to Charles Darwin, the biological mechanism that drives evolutionary change is natural selection. Natural selection is the process by which individuals with favorable traits that allow them to better survive and reproduce are more likely to pass on those traits to future generations. This leads to the gradual accumulation of beneficial traits in a population over time, resulting in evolutionary change.
