An independent variable is

2 answers:

8 0

A variable that is not dependent, e.g. when inserting soap into water to test its surface tension, the independent is soap. It is the change that is controlled in the experiment.

In the Cori cycle, when glucose is degraded by glycolysis to lactate in muscle, the lactate is excreted into the blood and retur

Kay [80]

Answer:

Explanation:

Glycolysis is the breakdown of glucose while gluconeogenesis is the formation of glucose. Both pathways are almost the same except that the non-reversible reactions in glycolysis requires another enzyme during gluconeogenesis.

Glycolysis is a 10-step multi-enzyme pathway, in which three of these 10 steps are non-reversible. It is these three steps that basically differentiates the glycolytic pathway from gluconeogenesis. These three steps are bypassed by different enzymes during gluconeogenesis

1. The correct option here is c

Glyceraldehyde 3-phosphate dehydrogenase converts glyceraldehyde 3-phosphate to 1,3-bisphosphoglycerate in glycolysis. This reaction is however a reversible reaction, hence this enzyme also converts 1,3-bisphosphoglycerate to glyceraldehyde 3-phosphate during gluconeogenesis.

2. The correct option here is b

Glucose 6-phosphatase converts glucose 6-phosphate to glucose during gluconeogenesis

3. The correct option here is d

Alcohol dehydrogenase converts ethanol into acetaldehyde. This reaction is not present in both glycolysis and gluconeogenesis and hence the enzyme is not involved/present in these pathways.

4. The correct option here is b

Phosphoenol pyruvate carboxykinase converts oxaloacetate to phosphoenol pyruvate during gluconeogenesis

5. The correct option here is a

Phosphofructokinase-1 converts fructose 6-phosphate to fructose 1,6-bisphosphate during glycolysis

6. The correct here is c

Phosphoglycerate mutase converts 3-phosphoglycerate to 2-phosphoglycerate during glycolysis. This reaction is however a reversible reaction and hence this same enzyme converts 2-phosphoglycerate to 3-phosphoglycerate during gluconeogenesis.

7. The correct option here is a

Hexokinase converts glucose to glucose 6-phosphate during glycolysis.

8. The correct option here is d

Pyruvate dehydrogenase converts pyruvate to acetyl-coA. This reaction is one of the fates of pyruvate. This reaction is however not present in both glycolysis and gluconeogenesis and hence the enzyme is not involved/present in both also.

Habituation occurs in the _____; sensory adaptation occurs in the _____.

Tomtit [17]

According to experts, habituation occurs in the body. It is when there is a reduced physical response to a stimulus after one has been exposed to it repeatedly.

Sensory deprivation, on the other hand, occurs in the brain. This is when ones senses no longer have the same response to stimuli that is continuous or unchanging.

All vertebrate embryos have _____ at some point during embryonic development, indicating a common evolutionary ancestor

aivan3 [116]

All chordates chare four structures. One of the is the tail. All vertebrate embryos have _<u>a tail</u>__ at some point during embryonic development, indicating a common evolutionary ancestor.

<h3>What is the relationship between chordates?</h3>

The evolutionary relationship between species is reflected in the similarities or differences in the patterns of embryonic development.

All chordates belong to the Chordata phylum, and share four main characteristics,

Notochord, which is a precursor of the dorsal spine.
Nerv cord, dorsally located and parallel to the notochord.
Pharyngeal clefts
Tail

All chordates express these structures at some point in their lives, especially in the early stages of embryogenesis. Many of them can be lost with animal development and become vestigial structures.

The tail is a vestigial structure in many vertebrates.

Vestigial structures are those body parts, genetically determined, that have been retained during the evolution of the taxonomic group but have lost or reduced their original function.

Such vestigial structures were plenty functional in the ancestors of new species, but now are typically degenerate, stunted, or rudimentary, and tend to be much more variable than homologous non-vestigial parts

All vertebrates develop a tail at some point in their embryonic life, even humans. However, this structure lost its original function in several species, so after a period of embryogenesis, this tail disappears, and its forming vertebras get fussed with each other composing the coccyx.

In many animals, the function of the tail is to stabilize, equilibrate and mobilize. But in humans, for instance, the coccyx has lost this function but is still an area of muscle insertion.

The correct option is Tail.

All vertebrate embryos have _<u>a </u><u>tail</u><u>_</u> at some point during embryonic development, indicating a common evolutionary ancestor.

) what foods have high levels of iron? look at the food pyramid; items in the meat group generally have a lot of iron.

Elis [28]

Surprisingly chocolate actually contains a fair amount of iron. Red meats are known to contain iron, one thing in particular is blood (yes that is sometimes eaten, and it contains a lot of iron). Such organs of animals that are high in iron include the spleen and or marrow.

If you wish to go vegetarian red veggies tend to be high in iron, one in particular are beets (yes, i know, they aren't red until processed)
