list 2 electron carriers and explain the function of each when in the oxidized state and in the reduced state
Answer: Flavin Adenine Dinucleotide (FAD)
Nicotinamide Adenine Dinucleotide (NAD)
Oxidation and reduction are coupled reactions in which electrons are transferred form one atom to another atom. Reduced compounds donate oxygen or accept hydrogen and oxidized compounds accepts oxygen or donates hydrogen.
So, when the electron carriers are in reduced condition, they accept hydrogens from different metabolic pathways, like glycolysis and TCA cycle, etc. In oxidized state they enter into ETC and donate protons for ATP synthesis. For example, 1 NADH gives 2.5 ATP and 1 FADH2 gives 1.5 ATP.

D. Gaba is a chemical that affects neuronal function but is not stored in presynaptic vesicles.
The main inhibitory neurotransmitter in the fully developed mammalian central nervous system is gamma-aminobutyric acid, or GABA. Its main function in the neurological system is to lower neuronal excitability. In several nations, GABA is offered as a dietary supplement.
Because it inhibits or blocks some brain messages and lowers nervous system activity, GABA is referred to as an inhibitory neurotransmitter. GABA has a calming impact when it binds to the GABA receptor protein in your brain. Anxiety, worry, and fear can all be relieved with the use of this.
People who take GABA orally as a supplement can experience relief from anxiety and persistent stress. Studies have shown that taking supplements helped with relaxation and anxiety relief.

4 how could you use a phylogeny to make predictions about the origin and maintenance of the behaviors you observed?
A phylogeny can be used to make predictions about the origin and maintenance of the behaviors by tracing the ancestral history of an organism even at the genetic level and even the prediction about future could be made.
Phylogeny is the diagrammatic depiction of the evolutionary and ancestral roots of an individual or a group of species, or of different species. This is done by establishing relations by making lines and connecting them to show the describe the connection.
Ancestral history is the roots and descent of the an individual. It depicts the fathers and fore-fathers of an individual and also its distant relatives.

During glucose catabolism, 686 kcal of energy are made available to do work. A minimum of 686 kcal are required for the anabolism of the same molecule. In practice, more energy is required. Why is this the case?.
More energy is needed because not all energy transduction processes are 100 percent effective. More cellular energy is needed since there are inefficiencies.
Cellular energy is mostly produced by the breakdown of carbohydrates, especially glucose. the total oxidative decomposition of glucose into CO2 and water
G°′= -686 kcal/mol is the amount of free energy produced by the process. Glucose is oxidized within cells in a sequence of stages associated with the creation of ATP to capture this free energy in usable form.
Almost all cells go through the process of glycolysis, which is the first step in the breakdown of glucose. Without oxygen, glycolysis takes place and can supply all of the anaerobic organisms' metabolic energy. Glycolysis, however, is only the first step in the degradation of glucose in aerobic cells.

One kind of carbohydrate is referred to as a Glucose is a basic sugar also referred to as dextrose (monosaccharides). Greek for "sweet" is C6H12O6, which is the molecular formula for glucose. It is the primary free sugar that circulates in higher animals' blood and can be found in fruits and honey.
Controlling its metabolism is essential since it supplies the energy required for cell activity (see fermentation, gluconeogenesis). Each starch molecule, which serves as plants' primary source of energy, is composed of thousands of linear glucose units.
Another important linear molecule that is primarily composed of glucose is cellulose. Dextrose is the ingredient in D-glucose.

What two significant proteins of the muscles are involved in the contraction and relaxation of your muscles?.
The two most important are the contractile proteins actin and myosin. Among the regulatory proteins, troponin, tropomyosin, M-protein, beta-actin, gamma-actin and C-protein are great importance.
Which protein is found in muscles?The myofibrillar protein components most important for muscle fiber structure are actin and myosin. They are the most abundant proteins in muscle and are directly involved in the ability of muscle to contract and to relax.
What causes contraction and relaxation of muscles?Energy released from ATP by myosin ATPase activity results in the cycling of the myosin cross-bridges with actin for contraction. Thus contractile activity in smooth muscle is determined primarily by the phosphorylation state of the light chain of myosin—a highly regulated process.

Modern travel along with migration reduces the probability of genetic drift having an effect on the evolution of humans.
In the field of biology, genetic drift can be described as a process by which an existing common gene variant becomes suppressed or caned in a population due to another, better gene variant being introduced into a population.
However, as a result of modern traveling, a population already will have mixed gene variants. This is because of the frequent migrations and travels that a population is not confined to just one gene variant. Hence, this excessive modern travel reduces the probability of genetic drift among humans.

Why are parasite numbers pyramids often inverted, with the bottom level smallest?.
One producer might have a lot of parasites; thus, parasite numbers of pyramids are sometimes inverted, with the bottom level being the smallest.
In parasitic food chains, a number pyramid is discovered to be inverted. In these food chains, a single producer typically supports a large number of parasites. More hyper-parasites are supported by the parasites in turn. In this pyramid, the number of people at each level rises from the lowest to the highest.
A graphical representation of the number of creatures at each trophic level is a pyramid of numbers. Given that producers are always more numerous than other trophic levels in an ecosystem, it is a vertical pyramid. There must always be enough plants at the bottom to create food, hence the pyramidal design. If not, the entire food chain would be destroyed. No predator can be as common as its victim at the upper level.

If pacific field male crickets in hawaii attract females by rubbing their wings together to sing, why is it that in some places up to 90% of the males no longer sing? how could this have evolved?.
Answer:

Explanation:
A certain mutation causes crickets to stop singing; and not for no reason, it happened as a result of parasitic flys that used the song to find hosts-- and although it worked and fewer crickets died from the parasite it also meant that certain crickets couldn't attract females. This evolved as a way to prevent the parasites from finding crickets and killing them but unfortunately also prevents females from finding them. I hope this helps!
What is the correct sequence of events for activation of a b cell by a t-dependent antigen?.
The correct sequence of events for activation of B-cells by T-dependent antigen is recognition of antigen, fragmentation, binding and secretion.
The process can be understood as firstly immunoglobulin receptors on the B cell recognize and bind with the antigen, secondly an antigen fragment in complex with MHC class 2 is displayed on the B cell's surface, thirdly the MHC-antigen complex binds a receptor on a TH cell and finally the TH cell secretes cytokines that activate the B cell. B-cells are the antibody producing cells that produce antigen specific immunoglobin molecule to fight against the pathogens such as bacteria or fungi. These B-cells are found in bone marrow of an individual. Lesser number of B-cells in the body makes it prone to infections as the immune system gets weak. T cells are the types of white blood cells primarily involved in directly killing of infected host cells, activating other immune cells, producing cytokines and regulating the immune response.
