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.

DNA codes for proteins by the sequence of nucleotides in the DNA. Each set of 3 nucleotides codes for a specific amino acid. Sometimes, a change in a nucleotide does NOT change the amino acid (and therefore, the protein) because some amino acids have more than one set of 3 nucleotides that code for them

Explanation:

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

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.

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.

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.

I cannot see the cells to answer number 4, but for number three, bacteria is a prokaryote and fungal cells are eukaryotes. You can most likely determine this by the presence of a nucleus (a prokaryote cell will not have one where a eukaryotic cell will).

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.

Explanation:

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.

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.

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.

Explanation:

Capture hypothesis is presented by the Urey and was dominant up to the 60s which states that the Moon was an asteroid-like wandering structure that formed somewhere far in the solar system and was captured by Earth's gravity while it was wandering.

The most dominant and popular theory for the origin of the moon is the giant impact hypothesis says that it is formed from the debris left after the collision of the earth and Theia a Mars-sized body.

Telescopes are tools engineered for collecting light from any part of the electromagnetic spectrum.

Scientists estimated that the age of the whole universe to be nearly 14 billion years with the help of Hubble's pictures and pictures from the Probe of Wilkinson

1. capture

2. giant impact hypothesis

3. electromagnetic spectrum

4. cold

5. 14

6. The moon's mass is much lower than the earth's; therefore, its gravity isn't strong enough to hold an atmosphere. This lack of an atmosphere and the moon's small size allowed it to become cool enough to the point at which it completely solidified. Thus, the moon doesn't have any plate tectonic activity.
