How is a single cell similar to a gray wolf

Answers

Answer:

Grey wolf optimizer (GWO) is a newly developed metaheuristic inspired by hunting mechanism of grey wolves. The paramount challenge in GWO is that it is prone to stagnation in local optima. This paper proposes a cellular grey wolf optimizer with a topological structure (CGWO). The proposed CGWO has two characteristics. Firstly, each wolf has its own topological neighbors, and interactions among wolves are restricted to their neighbors, which favors exploitation of CGWO. Secondly, information diffusion mechanism by overlap among neighbors can allow to maintain the population diversity for longer, usually contributing to exploration. Empirical studies are conducted to compare the proposed algorithm with different metaheuristics such as success-history based adaptive differential evolution with linear population size reduction (LSHADE), teaching-learning based optimization algorithm (TLBO), effective butterfly optimizer with covariance matrix adapted retreat phase (EBOwithCMAR), novel dynamic harmony search (NDHS), bat-inspired algorithm (BA), comprehensive learning particle swarm optimizer (CLPSO), evolutionary algorithm based on decomposition (EAD), ring topology PSO (RPSO), crowding-based differential evolution (CDE), neighborhood based crowding differential evolution (NCDE), locally informed particle swarm (LIPS), some improved variants of GWO and GWO. Experimental results show that the proposed method performs better than the other algorithms on most benchmarks and engineering problems.

A recently created metaheuristic called the "grey wolf optimizer" (GWO) was influenced by the way that grey wolves hunt. The main problem with GWO is that it can become stuck in local optima.

What is GWO?

In this study, a topologically structured cellular grey wolf optimizer is proposed (CGWO). There are two features of the suggested CGWO. First off, interactions between wolves are limited to those with whom they share topological neighbors, favoring exploitation of CGWO.

Second, the population variety can be preserved for a longer period of time by a technique of information transmission involving overlap among neighbors, usually promoting exploration.

The proposed approach is compared empirically against other metaheuristics, including the teaching-learning based optimization algorithm (TLBO), successful butterfly algorithms, and success-history based adaptive differential evolution with linear population size reduction (LSHADE).

Therefore, A recently created metaheuristic called the "grey wolf optimizer" (GWO) was influenced by the way that grey wolves hunt. The main problem with GWO is that it can become stuck in local optima.

A position effect variegation (PEV) phenotype can be used to identify new genes that regulate heterochromatin formation. For example, strains of Drosophila melanogaster with the white variegation phenotype can be subjected to mutagenesis to screen for mutations in other genes that suppress PEV, meaning the mutation results in a lower white pigment production. Using what you know about the enzymes that control heterochromatin spreading, describe one mutation that you would expect to be a suppressor of variegation

Answers

Answer:

by mutation of genes encoding histone modification enzymes that lead to loss of gene repression by the alteration of the chromatin structure

Explanation:

Histone methylation is an important epigenetic modification involved in regulation of gene expression. Histone methyltransferases and histone demethylases are enzymes capable of modifying the chromatin structure by adding or removing methyl groups of the N-terminal of the core histones, respectively. There are suppressor of variegation (Su-var) enzymes capable of removing activating chromatin marks such as, for example, histone H3 lysine methylation, thereby mutations in these epigenetic modifiers may result in a loss of gene silencing by directly opening the chromatin structure. For example, Su(var)3–9 is a histone lysine methyltransferase enzyme that controls the formation of heterochromatin.

How do mutation, genetic recombination during sexual reproduction, and lateral gene
transfer produce genetic variation?

Answers

A mutation occurs when there are changes in the gene structure of organisms. It may either increase or decrease the fitness of organisms. However, for mutations to be evident in an organism, it must be inherited by the offspring.

On the other hand, genetic recombination occurs during the sexual reproduction of two parents. During this process, different gene combinations or genotypes are produced. This event is similar to shuffling a deck of cards.

Lateral gene transfer occurs when the genetic material is transferred between organisms. This is not the same as transferring the genes from parent to offspring. This process usually occurs in single-celled organisms such as bacteria and plasmids.

When the mutation, genetic recombination at the time of the se-xual reproduction so there should be the change in the structure of gene.

What happen when mutation, genetic recombination generated:

The mutation should be arise at the time when there should be change in the gene structure of an organism.

The genetic recombination arise at the time of se-xual reproduction with respect to the two parents.

And, Lateral gene transfer arise at the time when the genetic material should be shifted between the organism

The option that is not a major tectonic plate is known as Australian. Thus, the correct option for this question is E.

What is a Tectonic plate?

The tectonic plate may be characterized as a type of gigantic piece of the Earth's crust and uppermost mantle. They are generally constructed up of the oceanic crust and continental crust.

Earthquakes take place around mid-ocean ridges and the large faults which definitely mark the edges of the plates. Due to this, the surface of the earth is cracked into moderate to larger pieces called plate tectonics. The lithosphere of the earth is correspondingly divided into seven major and some minor plates.

Therefore, the option that is not a major tectonic plate is known as Australian. Thus, the correct option for this question is E.

B.The frequency of the genes in one individual

C.The number of genes in the species

D.The number of genes in one chromosome​

Answers

Answer:

A. The frequency of the genes in the population

Explanation:

Genes are fundamental units that are part of the hereditary. The genes help offspring to survive and reproduce, then the frequency of genes in the population will increase. Hence, Option A is correct.

What are genes?

Genes are the functional units of heredity, genes are made up of DNA. Four factors change gene frequencies in a population namely migration, mutation, selection, and random genetic drift.

Gene frequency is called allele frequency. It remains constant from generation to generation if there are no distributing factors. The alteration in the genes causes the change in the frequency that plays an important role in variation and evolution.

The frequencies of genes increase when they are selected favorably. Darwin proposed the theory of natural selection, which states that natural selection acts on favorable variations that occur among a species' individuals.

Therefore, if genes help their offspring to survive and reproduce then the frequency of a gene in a population will increase. Hence, the correct option is A.

Answers

Answer:

Structure: unicellular organisms (single-celled), no nucleus or membrane-bound organelles, genetic material usually composed of a single circular bacterial chromosome coiled up in a region of the cytoplasm

Function: metabolic functions are carried out in the bacterial cytoplasm

Replication: generally asexual (binary fission)

Explanation:

Bacteria are prokaryotic organisms, i.e., unicellular organisms that do not have a cell nucleus nor any membrane-bound organelles . Generally, the genetic material is composed of a single DNA circular molecule (bacterial chromosome), which is localized in a specific region of the cytoplasm (nucleoid region). Prokaryotic cells are usually smaller than eukaryotic cells (0.1 - 5 μm in size). In bacteria, metabolic functions (i.e., growth and reproduction) occur in the cytoplasm. The most important process of reproduction in bacteria is binary fission, a form of asexual reproduction where a single bacterial cell divides into two. Bacteria can also exchange genetic material by sexual reproduction mechanisms (i.e., conjugation, transformation and transduction). The main strategy to prevent outbreaks caused by bacteria is to know the conditions where they grow and reproduce. For example, Salmonella is a genus of infectious bacteria that may cause an outbreak. Salmonella infection may be prevented by eliminating conditions where they can multiply. Measures to prevent Salmonella outbreaks include cook food thoroughly (do not eat raw eggs or raw beef), refrigerate foods, wash hands, etc.
