Are viruses composed of cells?
Answer:
No
Explanation:
Viruses are not made out of cells. A single virus particle is known as a virion, and is made up of a set of genes bundled within a protective protein shell called a capsid. Certain virus strains will have an extra membrane (lipid bilayer) surrounding it called an envelope.
Answer:
Viruses are not composed of cells
When wood lice are placed in dry air, they increase their speed of crawling but without direction until they become gradually dehydrated. When the wood lice are placed in humid air, they move at first, but any activity they exhibited soon ceases and they become quiet. Wood lice placed in a container with dry air at one end and humid air at the other gradually congregate at the humid end. This transfer is achieved through what appear to be random rather than directed movements. This is an example of which of the following?
A.Taxis
B.Klinokinesis
C.Orthokinesis
B.Klinokinesis transfer is achieved through what appear to be random rather than directed movements.gradually dehydrated.
Klinokinesis is a type of movement that occurs in response to a change in an organism's environment, specifically a change in the quality or direction of light. It involves an adjustment of the organism's posture or orientation in relation to the source of light, without any forward or backward movement. For example, when a plant is exposed to light from one direction, it may bend or turn towards the light to optimize its exposure. This movement allows the plant to maximize its exposure to light for photosynthesis.
In the case of wood lice, the movements towards the humid end of the container in response to the change in relative humidity can be considered an example of klinokinesis. The wood lice are not moving forward or backward in a directed manner, but rather adjusting their posture or orientation to optimize their exposure to the more favorable humid conditions. The movement is random and not directed, and it serves to maintain the organism's homeostasis by avoiding the dehydrating conditions of dry air dehydrated.

Answer:
The correct answer is intragenic suppressor mutation.
Explanation:
A suppressor mutation partially or completely converses the effects of a different mutation. A suppressor mutation is of two kinds, that is, an intragenic suppressor and an intergenic suppressor. An intragenic suppressor converses the influence of a mutation at a distinct site in a similar gene.
On the other hand, an intergenic suppressor converses the influence of a mutation at a distinct locus of the gene. It is the intragenic suppressor mutation, which takes place in a similar gene where the occurrence of the first mutation had taken place. Therefore, the mutation, which hides the influence of another mutation at a location, which is different from the location of the original mutation, but taking place in a similar gene can be illustrated as the intragenic suppressor mutation.

Explanation:
Prokaryotes are organisms made up of cells that lack a cell nucleus or any membrane-encased organelles. This means the genetic material DNA in prokaryotes is not bound within a nucleus. In addition, the DNA is less structured in prokaryotes than in eukaryotes: in prokaryotes, DNA is a single loop while in Eukaryotes DNA is organized into chromosomes. Most prokaryotes are made up of just a single cell (unicellular) but there are a few that are made of collections of cells (multicellular).
Scientists have divided the prokaryotes into two groups, the Bacteria, and the Archaea. Some bacteria, including E Coli, Salmonella, and Listeria, are found in foods and can cause disease;1 others are actually helpful to human digestion and other functions.2 Archaea were discovered to be a unique life form which is capable of living indefinitely in extreme environments such as hydrothermal vents or arctic ice.
A typical prokaryotic cell might contain the following parts:
Cell wall: the membrane surrounding and protecting the cell
Cytoplasm: all of the material inside a cell except the nucleus
Flagella and pili: protein-based filaments found on the outside of some prokaryotic cells
Nucleoid: a nucleus-like region of the cell where genetic material is kept
Plasmid: a small molecule of DNA that can reproduce independently
Eukaryotes
Eukaryotes are organisms made up of cells that possess a membrane-bound nucleus (that holds DNA in the form of chromosomes) as well as membrane-bound organelles. Eukaryotic organisms may be multicellular or single-celled organisms. All animals are eukaryotes. Other eukaryotes include plants, fungi, and protists.
A typical eukaryotic cell is surrounded by a plasma membrane and contains many different structures and organelles with a variety of functions. Examples include the chromosomes (a structure of nucleic acids and protein which carry genetic information in the form of genes), and the mitochondria (often described as the "powerhouse of the cell").
What is the purpose of natural selection?
Answer:
The purpose of natural selection is not a conscious or intentional one, as it is not driven by a specific goal or purpose. Instead, natural selection is a fundamental process in biology that acts on heritable traits within populations over generations. It is a key mechanism of evolution.
Explanation:
The primary outcome of natural selection is the adaptation of organisms to their environment. Individuals with traits that are advantageous in a particular environment are more likely to survive, reproduce, and pass on those beneficial traits to their offspring. Conversely, individuals with traits that are disadvantageous are less likely to survive and reproduce, leading to a reduction in the frequency of those traits in the population over time.
Natural selection, therefore, acts as a filter that shapes the characteristics of populations, favoring traits that enhance an organism's survival and reproductive success in a given environment. Over many generations, this process can lead to the development of new species or the modification of existing ones, as populations accumulate adaptations that allow them to thrive in different ecological niches.
It's important to note that natural selection does not have an end goal in mind, nor does it necessarily lead to the "best" or most advanced organisms. Instead, it is a consequence of the interactions between organisms and their environment, constantly shaping and refining the traits of living beings based on their ability to survive and reproduce.
