) the cori cycle involves the conversion of ? a) glucose to pyruvate b) fructose in red blood cells c) glucose in the liver d) all of the above
The Cori cycle involves conversion of: (a) glucose to pyruvate; (c) glucose in the liver.
Cori cycle is the cycle involving the metabolism of lactate. Here, the lactate produced due to anaerobic process in the muscles is transported to the liver. In the liver the lactate is converted to glucose which is then transported to muscles for utilization and further converted into lactate.
Liver is the largest organ of the body that id a digestive organ as well as an endocrine organ. The bile juices secreted by the liver are used for the digestion of fats. On the other hand it also secreted hormones like insulin and glucagon.

neuron. parts and functions of each one. which part is the receiving area of the stimulus and which transmit the impulse?
Dendrites are the receiving area of the stimulus and axons transmit the impulse.
Neurons are specialized cells, located in the nervous system, which convey information. Axons, soma, and dendrite are all parts of a neuron. The myelin sheath, a fatty covering that surrounds some axons and serves as an insulator to speed up electrical signal transmission, is present on some axons. The dendrite is a branch-like extension that connects to the soma and delivers electrical stimulation. It also receives information from other neurons. Information is sent from the soma to the terminal buttons via an extended fiber called an axon. Neurotransmitters use a lock-and-key mechanism to chemically convey information from the terminal buttons, through the synapses, to the receptive dendrites. Together, the numerous neurotransmitters have an impact on cognition, memory, and behavior. Drugs are called antagonists to impede the functions of neurotransmitters, whereas agonists imitate those of neurotransmitters.

Lake Mungo, Australia
Cro magnon Man

The chronological order of given hominin fossils is Kaprina Neandertals ,Lake Mungo, Australia,Cro magnon Man and Kennewick Man.
What are fossils?
Any preserved remains, impression, or trace of any once-living object from a previous geological era is referred to as a fossil (from Classical Latin fossilis, lit. "obtained by digging"; Bones, shells, exoskeletons, animal or microbe imprints in stone, items preserved in amber, hair, petrified wood, and DNA traces are a few examples. The fossil record refers to all fossils together.
The invention of radiometric dating methods at the turn of the 20th century allowed geologists to calculate the precise ages of the rocks and the fossils they contain. Fossilization can occur as a result of a variety of processes, such as permineralization, casts and moulds, authigenic mineralization, replacement and recrystallization, carbonization, and bioimmuration.
Any member of the zoological "tribe" Hominini (family Hominidae, order Primates), of which only one species—Homo sapiens, or humans—exists today, is referred to as a hominin. The word is most frequently used to refer to extinct members of the human lineage, including some that are now well recognized thanks to fossil evidence, such H. neanderthalensis (the Neanderthals), H. erectus, H. habilis, and numerous species of Australopithecus. Furthermore, the genera Ardipithecus, Ororin, and Kenyanthropus are included in the Hominini, according to various authors.
The erect posture, bipedal mobility, larger brains, and behavioral traits including the use of specialized tools and, in some cases, verbal communication are some of the traits that have set hominins apart from other primates, both living and extinct.Therefore, the chronological order of given hominin fossils is Kaprina Neandertals ,Lake Mungo, Australia,Cro magnon Man and Kennewick Man.

The term "biological magnification" is frequently used to describe the process by which certain substances, such as heavy metals or pesticides, enter lakes, rivers, and oceans and then move up the food chain in progressively higher concentrations as they are incorporated into the diet of aquatic organisms like zooplankton. These aquatic organisms may then be consumed by larger fish, larger birds, animals, or humans.

When a neuron discharges an electric signal, it is referred to as b. an action potential. An action potential is a quick succession of voltage changes across a membrane.
An electrical charge that moves along the neuron's membranes is called an action potential or nerve impulse. An action potential is an electrical signal that is sent out by a neuron. An action potential is a quick succession of voltage changes across a membrane. The permeability of each ion and the relative ratio of extracellular to intracellular ions determine the membrane voltage, or potential, at any given time.

We are able to distinguish between the hba (Hemoglobin beta globin) allele and the hbs alleles in our lab because HbA allele produces shorter PCR product than HbS.
Sickle hemoglobin (HbS) is caused by a point mutation in the two subunits of normal hemoglobin (HbA), resulting in nucleated polymerization and pathology.
There are at least two variants (or alleles) of the HBB gene: HbA and HbS. The HbA allele provokes no problems. The HbS variant can result in either sickle cell trait or sickle cell disease. This allele tends to cause red blood cells to "sickle" rather than forming donut shapes.

how does the quantitative measurement of npp help explain variation in the biomass of different trophic levels across ecosystems?
Quantitative measurement of net primary production (NPP) explains that the energy transferred to the next trophic has a different amount from the energy obtained in the previous trophic.
Net primary production or NPP is energy stored as biomass by plants. NPP is obtained from the calculation of gross primary productivity minus the rate of loss of energy for metabolism and maintenance.
Energy cannot be created, but can be changed from one form to another. Energy is only transferred from one trophic level to the next through the food chain. The energy transferred is NPP in the form of biomass at the first level which is then transferred to the next level when a consuming process occurs. Therefore the amount of energy transferred to the next trophic level is smaller than the energy available at the previous level because it has been reduced for metabolism and maintenance.

explain how the structure of a chloroplast (its membranes and thylakoids) makes its function (the chemical reactions of photosynthesis) more efficient.
Answer:
These internal membranes stack on top of each other, just like a stack of pancakes.
The structure of a chloroplast, specifically its membranes and thylakoids, makes its function, the chemical reactions of photosynthesis, more efficient because it provides a large surface area for the reactions to occur on and a way to organize the reactions in a sequence that allows the products of one reaction to be used immediately in the next reaction.
The membranes of a chloroplast are made up of two layers of phospholipid molecules, which form a lipid bilayer. This structure provides a large surface area for the chemical reactions of photosynthesis to occur on. The thylakoids, which are stacks of membrane-bound compartments, increase the surface area even further.
In addition, the structure of the thylakoids allows the reactions of photosynthesis to be organized in a sequence that allows the products of one reaction to be used immediately in the next reaction. The thylakoids are arranged in stacks called grana, which are interconnected by strands of thylakoid membrane called stroma lamellae. The thylakoid membranes within a granum are organized into discrete units called photosystems, which are the sites of the light-dependent reactions of photosynthesis. The thylakoid membranes within the stroma lamellae are the site of the light-independent reactions of photosynthesis. This organization allows the products of the light-dependent reactions, which are carried out in the thylakoid membranes of the grana, to be used immediately in the light-independent reactions, which take place in the thylakoid membranes of the stroma lamellae.
Overall, the structure of a chloroplast, with its membranes and thylakoids, provides a large surface area for the reactions of photosynthesis to occur on and a way to organize the reactions in a sequence that allows the products of one reaction to be used immediately in the next reaction. This makes the function of the chloroplast, photosynthesis, more efficient.
