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.

structures found in eukaryotic cells but not in a bacterial cells are?
Answer:
Bacterial cells do not have a nucleus. They also lack membrane-bound organelles, such as mitochondria or chloroplasts. The DNA of a bacterial cell is also different from a eukaryotic cell.
Explanation:
Eukaryotic cells are by definition those that have a membrane-bound nucleus, a morphological component that is absent from bacterial and archaeal cells.
What is the difference between eukaryotic and prokaryotic cells?Eukaryotic cells are distinguished by numerous membrane-bound structures in addition to the nucleus, including the endoplasmic reticulum, Golgi apparatus, chloroplasts, mitochondria, and others.
Prokaryotic cells lack membrane-bound structures, whereas eukaryotic cells do, including the nucleus.
The existence of mitochondria and chloroplasts, the cell wall, and the makeup of chromosomal DNA are all examples of differences between the cellular structures of prokaryotes and eukaryotes.
Therefore, prokaryotic cells are the name for bacteria's cells. Eukaryotic cells are cells that are found in mammals, plants, and fungi.

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.

Binary fission is a method of cell division used by prokaryotes to reproduce. This procedure involves splitting one cell into two and copying the chromosome, just like mitosis in eukaryotes. Thus option B is correct.
What is simple structure of prokaryotes?Prokaryotic cells lack organelles, have no nucleus, and are significantly smaller than eukaryotic cells.
A cell wall protects every prokaryotic cell. Many additionally include a polysaccharide-based capsule or slime layer.
The nucleoid of prokaryotic cells normally houses a single, circular chromosome. Prokaryotic cells can replicate more quickly than eukaryotic cells because they typically only contain one circular chromosome.
A prokaryotic cell can really go through two cycles of DNA replication before the cell divides.
Therefore, simple structure of prokaryotes allows them to reproduce quickly and effectively.

A short double-stranded RNA, one of whose strands can block gene expression
A double-stranded RNA that is formed by cleavage of hairpin loops in a larger precursor
An RNA sequence that can block the expression of some transposons
Answer:
A short double-stranded RNA, one of whose strands can block gene expression
Explanation:
SiRNA, also known as short interfering RNA, is are short double stranded DNA that binds to mRNA for the purpose of destroying the mRNA sequence, hence, preventing it from being translated into a protein.
According to this question, SiRNA can be described as a short double-stranded RNA, one of whose strands can block gene expression (translation of mRNA).

AT 8:00 AM you leave home and walk 0.5 km to a friend's house. At 11:30 AM you return home, then travel by car to the mall, which is 10 km away, and arrive at 11:45 AM. What is the total distance traveled?
Answer:
11km
Explanation:
The total distance travelled is the sum of the distance as follows:
- from home to friend's house
- from friend's house back home
- from home to the mall
According to this question;
* I walked from my house to my friend's place and covered 0.5km
* I walked back from my friend's house home in the same 0.5km
* I drove to the mall from my house and covered a distance of 10km
Hence, the total distance covered is 0.5 + 0.5 + 10
= 11km

It has a negative impact on the environment by providing new niches for wildlife to inhabit.
Answer:
It has a negative impact on the environment by allowing toxic chemicals to harm wildlife
Mining affects the environment and has a negative impact on it, this type of human activity produces toxic chemicals that harm wildlife.
What are the impacts of mining?Mining has a significant impact on the environment, as the development of this activity almost always involves suppression of vegetation, exposure of the soil to erosive processes with changes in the quantity and quality of surface and underground water resources, in addition to causing air pollution.
With this information, we can conclude that Mining affects the environment has a negative impact on the environment, allowing toxic chemicals to harm wildlife.
