46. If a species has experienced a genotype mutation that has greatly reduced its population size, but later the population increases, which of the following is most likely the consequence on the surviving population?
Organisms in the surviving population will be genetically superior, which will strengthen the population.
The natural selection of the surviving population will move from a normal selection to a disruptive selection.
The surviving population will be very different than the original population.
The surviving population will have very little genetic variation.
Answer:
Organisms in the surviving population will be genetically superior, which will strengthen the population
Explanation
Mutation are the fundamental forces of evolution,as they fuel the variability in the population
The following is most likely the consequence on the surviving population as Organisms in the surviving population will be genetically superior, which will strengthen the population.
What is genotype mutation?Mutation is the last supply of latest alleles in plant pathogen populations. Small populations have fewer alleles because of genetic glide and additionally due to the fact fewer mutations are generated in a small populace.
As a end result of the more occurrence of useful mutations, large populations of longer sequences can growth their health greater easily. It may also appear unexpected that populace length makes a distinction at mutation prices this small, however large populations have a bonus at numerous levels.

Explanation:
Cual seria el recorrido de una molecula de glicosa desde que es absorbida en el intestino delgado hasta que es metabolizada en el cerebro ?
Answer:
Del intestino delgado ---- torrente sanguíneo --- célula u órgano de almacenamiento.
Explicación:
Después de la absorción de glucosa por el intestino delgado, las moléculas de glucosa se difunden por un gradiente de concentración hacia la sangre capilar dentro de las vellosidades y estas moléculas de glucosa se liberan en el torrente sanguíneo. Cuando las moléculas de glucosa se agregan al torrente sanguíneo, la glucosa puede usarse para la producción de energía o almacenarse en nuestros cuerpos, que puede usarse cuando sea necesario. Si nuestro cuerpo necesita energía esta glucosa es absorbida por las mitocondrias de las células para la producción de energía mientras que por otro lado, si no se requiere energía, estas moléculas de glucosa se almacenan en diferentes órganos en forma de glucógeno.

Research the Clements successional theory and answer the following questions.
Were any scientific investigations conducted for proposing the theory? Was this theory tested or simply expected?
Were there any objections to the Clements theory?
Has the theory been subjected to peer review and publication?
Did the scientific community accept the theory?
Answer: The theories are tested under the controlled conditions of the experimental set up. On the basis of the above description, we can say that the scientific investigations are done in the form of experimentation trials before proposing a theory. The theory is tested and is not simply expected.
A theory is a well-established, tested explanation that provides a unified description of some aspect of the natural world.
Henry Gleason objected to the Clements theory. He emphasized that succession is more dependent on abiotic factors and their interactions with the environment.
Yes, the theory was published and widely spread.
Nearly all (around 97%) of the scientific community accepts evolution as the dominant scientific theory of biological diversity. Scientific associations have strongly rebutted and refuted the challenges to evolution proposed by intelligent design proponents.
Clements described plant succession as a developmental process that ultimately resulted in a mature, or climax, community. This theory was tested, objected, and was not widely accepted.
What is Clements successional theory ?Clements concluded plant succession as a developmental process by which the community acquired well-defined series of stages.
This ultimately resulted in a climax community. The climax community was indicator and expression of the climatic conditions determining it.
Yes there were scientific investigations conducted for this theory.Yes this theory was first tested and not simply excepted. It was first tested for being theory of plant succession.Yes there were objections for this theory that expressed by Gleason. He assumed that identification in Clement theory of particular kinds of vegetation assumed to be of too much homogeneity.The theory was published but not widely among classical economists. It went through review before getting published.Thus, here one can conclude that Clements successional theory was tested, objected, and published.

6 Which of the following statements about shark teeth fossil evidence is not consistent with the scientific theory of evolution? (7 Points) A. Many fossils of Shark teeth have recently been found that are all the same size and color compared to modern sharks. B. Many fossils of Shał teeth have been found that show different sizes and serrations (saw-like edges). These fossil teeth have distinct differences and similarities to modern sharks. C. Many fossils of Shark scales have been found that have features of enlarged scales that resemble a brush. Our modern sharks do not have or need this type of scale to survive. D. A new shark fossil has been found that has characteristics in the size of the teeth and the serrations (saw-like edges) that are in between the older fossils found and the modern shark.
Answer:
A. Many fossils of Shark teeth have recently been found that are all the same size and color compared to modern sharks.
Explanation:
Evolution is the change in characteristics of a species over time and it relies on the process of natural selection.
The theory of evolution states that all species are related and gradually change over time.
Since all options except A show a change in the characteristics of shark teeth in the fossils found in relation to modern sharks, option A is the answer. Since, there is no change in characteristics between the Shark teeth in the fossils and that of modern sharks.
So, option A is the answer.

The heart pumps oxygenated blood to the _____ and deoxygenated blood to the _____. A) body:liver B) body:lungs C) brain:lungs D) lungs:nose Eliminate
Answer:
The Answer is B) body:lungs
Explanation:
The body sends oxygenated blood (blood enriched with oxygen) to the body where oxygen is used and blood becomes deoxygenated. This blood when received in heart is pumped to Lungs where oxygen is taken up by blood through alveoli in our lungs. This way deoxygenated blood gets oxygenated and is pumped to the rest of the body and the cycle repeats.
All other options are wrong as blood can only get oxygenated at lungs through small air chambers called alveoli where oxygenation takes place.

a. interact generally within cells
b. are changed by reactions
c. are carbohydrates
d. are not used up in reactions
e. force reactions to occur
Answer:
d. Are not used up in reactions
Explanation:
This is a property of enzymes. They are not used up since they don't participate in reactions. They just help increase the rate at which it occurs
A key feature of enzymes is that they force reactions to occur. Thus, the correct option for this question is E.
What are Enzymes?Enzymes may be defined as biocatalysts that increase the rate of a chemical reaction without being changed in the overall process. It may be thought that all sorts of cellular reactions or processes are mediated by enzymes.
Most of the enzymes are proteins. They are highly specific in nature. Enzymes also exhibit enormous catalytic power. They do not alter the equilibrium state of biochemical reactions.
Enzymes typically speed up the rate of a chemical reaction by lowering the activation energy of a particular reaction. Thus, it leads to the conversion of reactants into products at a faster rate.
Therefore, a key feature of enzymes is that they force reactions to occur. Thus, the correct option for this question is E.
