We used new tags for the population estimate a year later. If we assume the tags stay on well over the year, what changes the proportion of the old marked tags in the population and make the use of new tags more accurate? (Hint: look back at the assumptions made by the mark and recapture method).a. random loss of tags might sufficiently large to change the proportion of tagged fish.b. as tagged fish die and larvae that were not tagged reach maturity the proportion of tagged changes.c. The fish might eat the tags.d. we cannot assume tags would stay on longer than six months, so we need new tags for the fishfish.

6) based on evolutionary history
Answers
Answer:
Biological species concept defines species as individual in a population that can interbreed and produce viable offsprings. Therefore Biological species concept is not applicable for extinct species
Morphological means in relation to structure therefore, this concept relies on similarity of structure to classify species.
Phylogenetic refers to members having the same ancestor. It classifies species according to common ancestry. Hence it will be based on evolutionary history.
Morphological and phylogenetic- Will accommodate asexual reproduction and species acceptance criteria can be subjective.
Biological, morphological and phylogenetic-Together they are used by scientists in classification
Final answer:
In the context of biological species, it does not support asexual reproduction and is not for extinct species. Morphological species, rely on structure similarities, are used for classification, and have subjective species acceptance. Phylogenetic species are based on evolutionary history, supports asexual reproduction, and has subjective species acceptance criteria.
Explanation:
The three significant concepts of species include the Biological species concept, Phylogenetic species concept, and Morphological species concept.
1) Biological species - This concept does not accommodate asexual reproduction (2) and is not applicable to extinct species (2).
2) Morphological species (or morphospecies) - This concept relies on similarities of structures (3), is used by scientists in classification (4) and the species acceptance criteria can be subjective (5).
3) Phylogenetic species - This concept is based on evolutionary history (6), can accommodate asexual reproduction (1) and the species acceptance criteria can be subjective (5).
The morphological and phylogenetic concepts are used by scientists in classification (4) and their species acceptance criteria can be subjective (5).
All three concepts - biological, morphological, and phylogenetic - are all considered in the broader understanding and definition of species.

Heat is also produced as a result of this reaction.
GLYCOLYSIS:
- Glycolysis is the first stage of cellular respiration in living cells. It involves the breakdown of glucose molecules to produce pyruvate.
- During the process of glycolysis, four ATP molecules are produced (net = 2) alongside the pyruvic acid that is formed.
- However, just like every other catabolic reactions that involves breaking down of large molecules, glycolysis also release energy in form of heat.
Therefore, heat is also produced as a result of glycolytic reaction (cellularrespiration).

B. In maternal effect, an offspring will have the genotype of their mother.
C. In a reciprocal cross, if an offspring has the mother's phenotype for both crosses, cytoplasmic inheritance is responsible.
D. The direction of shell coiling in Lymnaea peregra is influenced by the orientation of the first cleavage division.
E. It is safe to say that a maternal effect is caused by the genotype, not the phenotype, of the parent producing the egg.
Answers
Answer:
Answer is D.
Explanation:
The first cleavage division can be explained or described as the series of first cellular division of the zygote after fertilization.
In this case, the process of recoiling of the shell of the snail can not be categorized as one of the examples at this stage.

OPTIONS:
A) biogeographic isolation affects the random changes that take place within gene pools
B) biogeographic isolation affects the changes in gene pools that result from which organisms are breeding
C) biogeographic isolation determines who will win competition for mates
D) biogeographic isolation determines the time that populations will breed
Answer:
A) biogeographic isolation affects the random changes that take place within gene pools
Explanation:
Organisms can become splitted and isolated from each other by biogeographical factors, thereby preventing the isolated population of species from interbreeding with each other. When this occurs, the isolated population, over time, evolve separately and later become distinct from each other leading to a change in the original gene pool.
Biogeographical factors uch as habitat isolation can cause a change in the original gene of a species population which have now become isolated geographically, and thus, evolve separately.
