In what order do the electrons move through the electron transport chain?
Answer:
Four Stages: Glycolysis (a transition reaction that forms acetyl coenzyme) A, the citric acid (Krebs) cycle electron transport chain, and chemiosmosis.
Explanation:
The flow of electrons through the components of the electron transport chain occurs in order of increasing reduction potential.
Electronic transport chain is the set of enzymatic complexes embedded in the mitochondrial membrane that oxidize NADH and FADH2, generating a proton gradient.
It basically comprises 2 processes:.
1) Electrons are transported across the membrane, from one carrier protein complex to another.
2) Protons are translocated through the membrane, which means that they are passed from the interior or mitochondrial matrix to the intermembrane space causing a proton gradient.
Oxygen is the final acceptor of the electron, combining with them and the H ion to produce water.
This chain comprises numerous associated components in the form of enzyme complexes, each of which has transmembrane proteins that support the complex on the inner mitochondrial membrane, an Fe-S flavoprotein, ubiquinone, and the cytochrome chain.
The electrons start out in order with very high energy, which they lose as they pass through the chain. In other words, the carrier molecules are reduced and oxidized, lowering electrons from high energy levels to lower ones.
Therefore, we can conclude that the flow of electrons through the components of the electron transport chain is carried out in order from high energy levels to lower ones.

The body works to maintain homeostasis in response to what conditions?
Answer:
so the body works to maintain homeostasis in response to internal or external conditions
Explanation:
Homeostasis is the process of maintaining a stable internal conditions, Homeostasis keeps internal conditions just right for cell function.
Its like if your hot your body with sweat to cool you down
OR
when your cold you shiver which contracts the things inside of your body so your body contains more heat rather than releasing it
An example of Homeostasis in response to internal conditions is:
when your body produces too much glucose, your body releases insulin to bring the level of glucose down
and when there isnt enough glucose your body releases glucagon to bring up the level of glucose to stable your blood sugar
Homeostasis has been the bodily process that is involved in maintaining the environment of the body. The body works to maintain homeostasis in response to internal and external changes.
What is homeostasis?Homeostasis has been defined as the steady internal environment for the maintenance of physiological processes. This involves the optimization of the variables and carious functions so that equilibrium can be achieved.
The factors involved in homeostasis are pH levels, temperature, glucose, etc. It has been the response of the cell towards the external environment so as to maintain balance. The homeostatic range is important for the proper functioning of the body.
The changes in the internal and external environment affect homeostasis as an increase in temperature in summer leads to sweating and a decrease in temperature in winter leads to shivering. It uses the feedback mechanism to maintain equilibrium.
Therefore, the process of homeostasis is in accordance with internal and external changes.

1. What did Linnaeus use to classify living things?
Answer:
Perhaps the single greatest contribution Linnaeus made to science was his method of naming species. This method, called binomial nomenclature, gives each species a unique, two-word Latin name consisting of the genus name and the species name. An example is Homo sapiens, the two-word Latin name for humans.
Explanation:
Can I have brainliest
It is from Google
Binomial nomenclature, which Carolus Linnaeus created, is a system for categorizing living things. Linnaeus was a Swedish botanist and biologist.
Binomial nomenclature is a biological system for naming organisms.
It is quite difficult to identify an organism internationally and keep track of the number of species when it has multiple local names.
Some of the features of binomial nomenclature that Linnaeus used to classify living things are:
Latin names are used because they are universal and consistent.
The process of naming each organism uniquely using the two words "genus" and "species."
The arranging of living things into a hierarchy, with each organism being given a position based on how similar it is to others.
Humans, for instance, are known as Homo sapiens. Its name, Homo, translates to "man" in Latin. The name of the species, sapiens, means "wise".
Therefore, Binomial nomenclature is used by Linnaeus to classify living beings.

(Q005) Humans are unusual because our cultural practices can actually change our environmental circumstances. We can change the environment in which natural selection acts on our traits. Describe how this process has played out in the evolution of adult lactose tolerance. Can you hypothesize any similar situations where our future evolution may be influenced by cultural practices we have today
Answer:
Lactose tolerance conferred an evolutionary advantage, thereby this beneficial mutation increased its frequency in the population
Explanation:
Originally, adults were unable to digest lactose. But approximately 8,000-10,000 years ago something remarkable happened: a mutation near the gene that produces the lactase enzyme appeared in a raising cattle population from Europe-Middle East, making adults able to digest lactose. Nowadays, many adults from different societies are tolerant to digest lactose because this mutation increased its frequency and extended to different populations. It is a classical example of how a beneficial mutation may eventually become the most common gene variant by increasing its frequency in the population, and, subsequently extending to other populations. It is possible to hypothesize that new mutations associated with human activities may appear in current human societies, thereby conferring an evolutionary advantage in the same way that lactose tolerance in cattle-raising people. For example, nowadays, mutations in human behavior-associated genes might confer beneficial social skills (thereby increasing the frequencies across time or across populations).

Explanation:
Consider the impact of each substance on cellular respiration. Each substance has an influence at the cellular level, and has no effect on hunger. Assume that the substances have no other impact on the cell other than the one described. Substance’s Effect: Makes the lipid bilayer of the inner mitochondrial membrane highly permeable to (H+) protons. Does it cause weight gain or loss?
Answer:
The correct answer is "Weight loss".
Explanation:
If the influence of material is such that it adversely affects the attachment of NAD+ to electrodes, it can help people lose weight. This because it will indeed necessarily imply that perhaps the ATP throughout the cells would've been whittled down unless the compound NADH could not have been established. This also suggests that because the body doesn't obtain adequate ATP, this also contributes to the breakdown of fat into some kind of type of stored energy which always promotes weight loss throughout the turn.When do you think the world's population will stop growing?

Which of the following might help reduce nitrate pollution? Use of synthetic fertilizers often leads to the contamination of groundwater with nitrates. Nitrate pollution is also a suspected cause of anoxic "dead zones" in the ocean. Which of the following might help reduce nitrate pollution? adding nitrifying bacteria to the soil using ammonia instead of nitrate as a fertilizer growing improved crop plants that have nitrogen-fixing enzymes adding denitrifying bacteria to the soil
Answer:
adding denitrifying bacteria to the soil
Explanation:
Denitrifying bacteria refer to microorganisms in soil that carry out the conversion of nitrates in soil to free atmospheric nitrogen.
Nitrogen gas (N2) is ultimately the product of denitrification of soil, however certain intermediate nitrogen species are also formed in the process. Some of these intermediates may include the following sequence of conversion; NO3− → NO2−→ NO + N2O → N2.
The chemical equation for denitrification is; 2 NO3− + 10 e− + 12 H+ → N2 + 6 H2O.
