Glycolysis and gluconeogenesis are opposing pathways in that they begin or end with the same metabolites and share common intermediates and/or enzymes. Yet, for energetic reasons, the two processes cannot be the exact reverse of each other. How is this possible
Answer:
Due to difference in their products.
Explanation:
Glycolysis and gluconeogenesis are not exact reverse to each other because in glycolysis, glucose is converted into pyruvate, adenosine triphosphate (ATP), NADH, protons i.e. hydrogen ions and water whereas in gluconeogenesis, pyruvate is converted into glucose and glycogen. So due to the formation of different products of each process we can say that glycolysis is not exact reverse of gluconeogenesis.

what is homostatis in biology
Answer:
Homeostasis, from the Greek words for "same" and "steady," refers to any process that living things use to actively maintain fairly stable conditions necessary for survival. The term was coined in 1930 by the physician Walter Cannon.
Explanation:
An ecologist samples the abundance of various species along an environmental gradient and fails to find clusters of species. Instead, peaks of abundance of dominant species are merely randomly spaced segments along a continuum. This distribution of species supports the
Answer:
This distribution of species supports Gleason´s Individualistic concept of a community.
Explanation:
This theory was proposed by Gleason and it states that plant species respond individually to environmental factors that continuously change at spatial and temporal levels. This means that the combination and distribution of plants in a certain point or area are unique because each vegetable species has a different distribution pattern and a different tolerance and abundance rate. Hence each species´ response curve to a certain gradient has its own shape and size and it different from other species curves.
Plants assembly growing in an area is the result of environmental conditions and migration rate of species. As every area is continuously getting propagules of different species, the survival success of each plant depends not only in environmental factors, but also depends on the tolerance to other new species and their interactions. This combination along a gradient always results in different composition and abundance of species. This is why a sample can not be confined to a clearly defined vegetable community.
This point of view is known as individualistic or continuum concept of vegetable community. Gleason believed that vegetable species were distributed as a continuum and that communities can not be identified as combinations of associated species that repeat in space.
where are genes located in a prokaryotes cell?
Here is a easy question summary the Interphase, prophase metaphase, anaphase and telophase step by step for each of the phase
Answer:
Interphase:
The DNA is present as uncondensed chromatin, which is not visible under a microscope. The DNA is contained within a clearly defined nucleus . Centrosomes and other organelles have been duplicated , and the cell is enlarged in preparation for division .
Prophase:
The DNA supercoils and chromosomes condense, becoming visible under a microscope). The chromosomes are comprised of genetically identical sister chromatids, which are joined at a centromere). Paired centrosomes then move to the opposite poles of the cell and form microtubule spindle fibers , the nuclear membrane breaks down, and the nucleus dissolves .
Metaphase:
The microtubule spindle fibers from both centrosomes connect to the centromere of each chromosome , microtubule depolymerisation causes spindle fibers to shorten in length and contract , causing chromosomes to align along the center of the cell.
Anaphase:
The continued contraction of the spindle fibers cause genetically identical sister chromatids to separate . Once the chromatids separate, they are individual chromosomes. The genetically identical chromosomes move to the opposite poles of the cell .
Telophase:
Once the two chromosome sets arrive at the poles, spindle fibers dissolve and chromosomes decondense, becoming invisible under light microscopes. Nuclear membranes reform around each chromosome set , and cytokinesis occurs concurrently, splitting the cell into two separate cells.

• How the knowledge of classification be applied to assess the characteristics of different organisms when visit to zoo, herbaria or gardens.(Students may do research on internet to answer this question )
plz correct answer
be quick
Answer:
Compare two organism on the physical features and mode of nutrition.
Explanation:
Organisms are classified in groups and sub-groups on the basis of similarities and differences. so in order to compare two organisms, start with the similarities that are present between them. If similarities are more so they belong to the same group or if differences are more than both are placed in different groups. for classification, see the physical appearance of organism, mode of nutrition and habitat etc. If organisms are identical, they belong to the same species, if one or two characters are different so their genus will be same but specie is different. In zoo animals are different from the animals which is present in garden so compare the physical features of zoo and garden animals.

Before working at the hospital, Beth was given a Mantoux skin test to detect tuberculosis. If it were positive, the site of the test would become hardened and red. What type of response is this?
The options are missing from the question,the missing options are;
a. Anaphylactic
b. Histamine
c. Immediate allergic
d. Delayed allergic
e. B-cell mediated.
The correct answer to the question is option D
DELAYED ALLERGIC.
Delayed allergic response is a type of late response to antigen that occurs 48-72hours after exposure to an antigen.
This type of allergic response is mediated by T-cells and macrophages.
They are otherwise known as delayed hypersensitivity response/reaction.
The response is delayed because there is sensitization upon first exposure to the antigen, therefore if there is a re-exposure,a secondary cellular response is initiated triggering the actions of the already sensitized T-cells and macrophages.

Which observation led Mendel to the idea that traits were controlled by more than a single factor? Crossing two purple-flowered pea plants always resulted in a purple-flowered pea plant. Crossing two white-flowered pea plants always resulted in a white-flowered pea plant. A trait that was not seen in the first generation may later reappear in the second generation. A trait that was not seen in the first generation was completely gone and never reappeared.
Answer:
The answer is option C.
Explanation:
Genetic traits are expressed by dominant and recessive genes, which show up in the phenotype according to their presence on the chromosomes.
Observing a trait that was not present in the previous generations suggests that this trait is recessive and did not have the chance to appear in the other generations before. This idea has led Mendel to the idea that traits were not controlled by only a single factor. So the answer is C.

Most fresh water fish are hypertonic, meaning their body cells contain more salt than the surrounding water. Since osmosis should push water into their cells, why don't they explode? They don'Ât drink any water because they get so much from osmosis. They have adapted to live with high osmotic pressure. They urinate a lot, so the water does not build up. Their cells have adapted to absorb salt. All of the above
Answer:
They urinate a lot, so the water does not build up.
Explanation:
Freshwater fishes are fishes that live in freshwater habitat i.e. little or no salt. This means that the fishes are hypertonic (have more salt) to their external environment. Due to their hypertonicity, freshwater fishes tend to take in more water via osmosis.
Freshwater fishes, however, do not explode despite this phenomenon because they pass out the excess water via urine waste. Freshwater fishes urinate a lot, hence, the absorbed water does not build up in their bodies.
