Members of the Euglenozoa move within their habitats with the aid of flagella.
The Euglenozoa is a diverse group of protists that includes organisms such as Euglena and Trypanosoma. These organisms possess a characteristic whip-like structure called a flagellum, which they use for movement.
Flagella are long, thread-like appendages that extend from the cell surface. They contain a complex structure of microtubules that enable them to beat in a coordinated manner, propelling the organism through its environment.
In the case of Euglenozoa, the flagella are typically located at the anterior end of the cell. The beating motion of the flagella creates forward movement or helps the organism change its direction.
By adjusting the movement of their flagella, members of the Euglenozoa can navigate through water or other liquid environments where they reside.
It is important to note that while flagella are the primary locomotory structures for Euglenozoa, some species within this group may also exhibit limited movement using pseudopodia (temporary extensions of the cell membrane) or other means.
However, flagella are the predominant organelles involved in the movement of Euglenozoa.

Explain how seismic waves are created and how they help scientists understand Earth's structure.
Seismic waves are created by sudden movements of materials inside the Earth. Volcanic eruptions, earthquakes, explosions and avalanches are examples of circumstances that create such movementd and could create seismic waves. Scientists benefit from them because the seismic waves can be recorded by seismographs. Data from seismic waves is often used in order to better understand the inner structure of our planet. The waves can even be use to map details of that structure. One example of it is how they calculate de depth of Earth's major layers by studying the tame that some waves takes to travel down into the Earth and get back to the surface.

The evolutionary steps in order are:
1. Vascular non-seed plants evolve
2. Vascular seed plants evolve (gymnosperms)
3. Vascular flowering plants evolve (angiosperms)
4. Non-vascular plants evolve
The correct order of the evolutionary steps is as follows: The first step is the evolution of vascular non-seed plants. These plants possess specialized tissues for conducting water and nutrients but do not produce seeds. Examples include ferns and horsetails.
The next step is the evolution of vascular seed plants, known as gymnosperms. Gymnosperms have vascular tissue and produce seeds that are not enclosed in a fruit. Examples include conifers like pine trees and spruces.
The third step is the evolution of vascular flowering plants, also known as angiosperms. Angiosperms are the most diverse group of plants and produce flowers and fruits. They have specialized structures for sexual reproduction and enclose their seeds within fruits. Examples include roses, apple trees, and grasses.
The final step is the evolution of non-vascular plants, often referred to as bryophytes. These plants lack true vascular tissue and include mosses, liverworts, and hornworts. It is important to note that these evolutionary steps occurred over millions of years, with each group building upon the innovations of the previous group, leading to the diverse plant kingdom we see today.

The inherited, progressive disorder of the muscles that affect movement and function is called muscular dystrophy.
A muscular dystrophy is a group of genetic disorders characterized by progressive weakness and degeneration of the skeletal muscles that control movement. It is a progressive disorder that results in muscle weakness and decreased muscle mass. It also causes issues with the heart and breathing muscles as it progresses. Muscular dystrophy is caused by a lack of a protein called dystrophin that helps maintain muscle integrity. In some cases, this lack of dystrophin is inherited, but in other cases, it is caused by a spontaneous genetic mutation. There are several types of muscular dystrophy, with Duchenne muscular dystrophy being the most common and severe form. Other types include Becker muscular dystrophy, limb-girdle muscular dystrophy, and myotonic dystrophy. Treatment for muscular dystrophy varies depending on the type and severity of the disorder.

Claim 5: Cells need glucose AND oxygen to release energy Claim 6: ALL?
Answer:
Claim 5: Cells need glucose AND oxygen to release energy.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage through the breathing of oxygen used to obtain energy from the food ingested.
Hence, cells need glucose and oxygen to release energy.
The statement 'cells need glucose AND oxygen to release energy' is correct (Claim 5).
Cellular respiration is a series of metabolic reactions by which aerobic cells used oxygen and the energy stored in the chemical bonds of foods (e.g., glucose) to produce ATP.
Cellular respiration has three main stages: glycolysis, the citric acid cycle and oxidative phosphorylation.
During glycolysis, a molecule of glucose is used to create two molecules of pyruvate, which enter into the citric acid cycle.
Oxygen is the last acceptor of electrons in the electron transport chain of oxidative phosphorylation.
In conclusion, cells need glucose AND oxygen to release energy.

One recent approach to vaccine development has been production of peptide vaccines. In these vaccines, antigenic peptides are injected instead of whole bacteria or viruses. Peptide vaccines have not been particularly useful against viral pathogens because viral infections require a CD8+ T cell mediated immune response. Why is a peptide vaccine unable to create such a response?
Answer:
Explanation below
Explanation:
Immunization is the process of protecting the body from infections. This can be divided into two, namely
1. Natural immunization
2. Artificial immunization
Natural immunization is the one that is being developed by the body naturally, to protect the body from infections. This is usually known as the white blood cells.
Artificial immunization is being developed through the introduction of atenuated organisms into the body, so that the body can react by producing antibodies against that infectious organisms. This is known as vaccination.
The peptide vaccines have been developed for the body to be able to produce antibodies against some infections.
It should be noted that, owing to the relatively small size of peptides, they are often weakly immunogenic by themselves and therefore require carrier molecules, to add chemical stability and adjuevating for the induction of a robust immune response.
