Answer:

The nucleosome core is composed of two each of histones H2A and H2B and H4

Explanation:

The nucleosome is the basic structural unit of all eukaryotic genomes. A nucleosome is composed of approximately 146 base pairs of DNA sequence wrapped around a core of histone proteins, which generally consists of two subunits of the histones H2A, H2b, H3 and H4, respectively (i.e., an octamer of histone proteins). Within the cell nucleus, the large DNA molecule is coiled into nucleosomes, this structure is further compacted into chromatin fibers and subsequently into higher-order organization structures to finally form a chromosome.

Extracellular polymeric substances help protect biofilms from issues such as drying out and predators. Option A

Biofilms are complex communities of microorganisms that adhere to surfaces and form a protective matrix. They can be found in various natural and artificial environments, such as riverbeds, medical devices, and plumbing systems. Biofilms provide advantages to the microorganisms within them, including protection from environmental stresses and predators.

One of the key components that helps protect biofilms is extracellular polymeric substances (EPS). EPS are complex mixtures of polysaccharides, proteins, and DNA that are secreted by microorganisms within the biofilm. These substances form a matrix that encases the cells, providing structural support and protecting the community.

EPS help biofilms resist drying out by retaining water and preventing desiccation. The polysaccharides in EPS can absorb and retain moisture, creating a hydrated environment within the biofilm even in dry conditions. This is crucial for the survival of the microorganisms within the biofilm.

Additionally, EPS serve as a barrier against predators. The matrix formed by EPS can make it difficult for predators, such as protozoa or grazing organisms, to access and consume the microorganisms within the biofilm. It acts as a physical defense mechanism, limiting the exposure of the microorganisms to predation.

While quorum sensing, becoming sessile (immobile), and autoinducers are all important mechanisms and processes associated with biofilms, they do not directly address the protection of biofilms from drying out and predators. So Option A is correct.

The correct answer is:

c. Populations - not individuals - change when natural selection occurs.

Natural selection is the process by which certain traits become more or less prevalent within a population over time in order to influence the reproductive success of individuals.

As individuals with certain traits survive and reproduce better, those traits become more prevalent within the population. This can lead to changes in the overall characteristics of the population over time. But it is the population that changes, not the individual organism. Individual organisms can change in response to their environment, but these changes are not passed on to their offspring.

Natural selection does not create new species. It simply leads to changes in the frequency of existing traits within the population. Furthermore, natural selection does not cause population traits to become “more perfect” over time. Rather, it just makes traits beneficial to survival and reproduction more common within the population.

Answer:

Jesus made every one evalution is false

When Charles Darwin introduced the theory of evolution through natural selection 158 years ago, the scientists of the day argued over it fiercely, but the massing evidence from paleontology, genetics, zoology, molecular biology and other fields gradually established evolution's truth beyond reasonable doubt. Today that battle has been won everywhere—except in the public imagination. Embarrassingly, in the 21st century, in the most scientifically advanced nation the world has ever known, creationists can still persuade politicians, judges and ordinary citizens that evolution is a flawed, poorly supported fantasy. They lobby for creationist ideas such as “intelligent design” to be taught as alternatives to evolution in science classrooms. When this article first went to press in 2002, the Ohio Board of Education was debating whether to mandate such a change. Prominent antievolutionists of the day, such as Philip E. Johnson, a law professor at the University of California, Berkeley, and author of Darwin on Trial, admitted that they intended for intelligent-design theory to serve as a “wedge” for reopening science classrooms to discussions of God.

The good news is that in 2005 the landmark legal case Kitzmiller v. Dover in Harrisburg, Pa., set binding precedent that the teaching of intelligent design in U.S. public schools is unconstitutional because the idea is fundamentally religious, not scientific. The bad news is that in response, creationists have reinvented their movement and pressed on. When they lost the ability to claim that creationist ideas are valid science, they switched to arguing that they were only supporting “academic freedom.” Worse, to further obscure the religious roots of their resistance, they now push for “critical analysis” of climate change, cloning research and other scientific endeavors that they paint as culturally oppressive.Explanation:

Answer and Explanation:

The brain is composed of three main structures, the cerebrum, cerebellum, and brain stem. The brain sends chemical and electrical signals throughout the body to regulate different biological functions and sense environmental changes. The brain communicates with the majority of the body through the spinal cord.

The portion of a Z-line that is between two nearby neighbors is known as a sarcomere (or Z-discs). The Z-line (derived from the German word "zwischen," which means between), which anchors the actin myofilaments, can be seen in between the I-bands in electron micrographs of cross-striated muscle.

The I-band region is located around the Z-line (for isotropic). The I-band is the region of thin filaments where thick filaments are not overlaid (myosin).

The I-band is followed by the A-band (for anisotropic). named after the characteristics they exhibit under polarized light. The full length of a single thick filament is contained within an A-band. There are both thick and thin filaments in the anisotropic band.

The H-zone is a paler area located within the A-band (from the German "heller", brighter). Known as a result of their lighter look under polarization imaging technology. The region of the thick filaments that lacks actin is known as the H-band.

A narrow M-line, which is derived from the German word "mittel," or "middle," emerges in the middle of the sarcomere, which is made up of cytoskeleton cross-links, within the H-zone.

The organelle marked with an X in the given options is the mitochondrion.

The correct answer would be mitochondrion.

Mitochondria are double-membraned organelles found in most eukaryotic cells. They play a crucial role in cellular respiration, which is the process of converting nutrients into usable energy in the form of adenosine triphosphate (ATP).

Mitochondria are often referred to as the "powerhouses" of the cell because they produce the majority of ATP required for cellular activities. They contain their own DNA and ribosomes, enabling them to partially control their own protein synthesis. The inner membrane of mitochondria is highly folded into structures called cristae, which increase the surface area available for energy production.

Mitochondria are involved in several metabolic processes, including the citric acid cycle and oxidative phosphorylation. During these processes, they utilize oxygen to break down carbohydrates, fats, and proteins, releasing energy that is used to generate ATP. This energy is essential for various cellular activities, such as muscle contraction, active transport, and synthesis of macromolecules.

Mitochondria also have other important functions in the cell. They participate in calcium signaling, regulate cell death through apoptosis, and are involved in the synthesis of certain molecules required for cellular function.

In summary, the organelle marked with an X is the mitochondrion. It is a vital organelle involved in cellular respiration and ATP production, often referred to as the "powerhouse" of the cell. Mitochondria have their own DNA, ribosomes, and a highly folded inner membrane, and they play critical roles in energy metabolism and other cellular processes

Science teachers consider practical sciences to be a valuable component of science education for several reasons:

Hands-on Learning: Practical sciences provide students with the opportunity to engage in hands-on learning experiences. This approach allows students to actively explore and manipulate materials, conduct experiments, and make observations.

Example: In a biology class, students may conduct a dissection of a preserved specimen to study the anatomy and structure of organisms. By physically dissecting and examining the different organs and systems, students gain a tangible understanding of the subject matter.

Application of Theory: Practical sciences enable students to apply theoretical knowledge acquired in the classroom to real-world situations. By engaging in practical activities, students can bridge the gap between abstract concepts and their practical applications, fostering a more comprehensive understanding of scientific principles.

Example: In a chemistry class, students might perform experiments to understand chemical reactions and concepts like stoichiometry. By actually mixing and observing different substances, measuring quantities, and analyzing the results, students can see how theoretical concepts translate into practical applications.

Development of Scientific Skills: Practical sciences help students develop essential scientific skills, such as critical thinking, problem-solving, observation, data analysis, and communication. Through practical activities, students learn to formulate hypotheses, design experiments, collect and analyze data, draw conclusions, and communicate their findings effectively.

Example: In a physics class, students could design and conduct an experiment to investigate the relationship between force and motion. By planning the experiment, taking measurements, analyzing the data, and presenting their findings, students enhance their scientific skills and develop a deeper understanding of physics concepts.

Engagement and Motivation: Practical sciences often increase student engagement and motivation in science education. Hands-on activities provide a more interactive and dynamic learning environment, making science more interesting and accessible to students. It can spark curiosity, promote active participation, and cultivate a sense of wonder and excitement about the natural world.

Example: In an environmental science class, students may visit a local ecosystem to conduct field observations, collect samples, and analyze the data they gather. By immersing themselves in the real environment and actively participating in the scientific process, students are more likely to be motivated and engaged in their learning.

Answer:

Sometimes molecules cannot move through the cell membrane on their own. These molecules need special transport proteins to help them move across the membrane. Facilitated diffusion is the diffusion of substances with the help of transport proteins in the plasma membrane. These special proteins are called channel proteins or carrier proteins, and they are attached to the cell membrane. In fact, they go through the cell membrane, from the inside of the cell to the outside. Facilitated diffusion is used for molecules that cannot diffuse rapidly through cell membranes on their own, even when the molecules are moving from high to low concentration areas. An example is the sugar plants and animals use for energy, called glucose. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient so it does not require the use of cellular energy.
