Polysaccharides are 1000s of monosaccharides joined together.These carbohydrates store energy and help build structural compounds. For example, plants use cellulose to build up their cell walls so they can stay rigid and grow towards the sunlight. Plants can store glucose energy in the form of starch in roots, fruits, and seeds. On the other hand, animals store glucose energy in the form of glycogen. When we don't have enough food to eat to replenish glucose in our cells, glycogen will release glucose energy as backup.

Answer:

Transcription and replication are important processes that occur in cells but have distinct differences.

Similarities between transcription and replication:

1. Both transcription and replication involve the synthesis of nucleic acids. In replication, DNA is copied to produce an identical DNA molecule, while in transcription, DNA is used as a template to produce RNA.

2. Both processes occur in the nucleus of eukaryotic cells, although replication also occurs in the cytoplasm of prokaryotic cells.

Differences between transcription and replication:

1. Template: In replication, the entire DNA molecule serves as the template for copying. However, in transcription, only a specific DNA segment, called a gene, serves as the template for synthesizing an RNA molecule.

2. Product: Replication results in the production of an identical DNA molecule, while transcription produces an RNA molecule that is complementary to the DNA template.

3. Enzymes involved: Replication requires the involvement of multiple enzymes, including DNA polymerase, helicase, and ligase. Transcription, on the other hand, involves RNA polymerase, which catalyzes the synthesis of RNA from the DNA template.

4. Base pairing: During replication, DNA bases pair with their complementary bases (A with T and C with G) to produce an exact copy. In transcription, RNA bases pair with complementary DNA bases (A with U and C with G), resulting in an RNA molecule complementary to the template DNA strand.

Overall, while transcription and replication involve the synthesis of nucleic acids, they differ in terms of their templates, products, enzymes involved, and base pairing patterns. These processes are essential for cell function and crucial in genetic information transfer and maintenance.

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:

The level of specialization is given by the function.

The function of the organ makes the cell as it becomes mature, its more specific function becomes.

First, a stem cell differentiates itself into a hepatic or neuronal cell, thus generating that its functions are limited compared to the rest of the stem cells.

After this process, throughout the cell development and maturation of the organ, its cells become more specific in a single activity.

Explanation:

The differentiation of the stem cells is regulated by the genetic code, the migration of these during the embryonic stage of the mouse and the external stimulation that these stem cells perceive.

Rainfall is the amount of precipitation that falls from the sky in any given period of time, usually measured in millimeters. Rain can come in a variety of forms, including light drizzle, heavy showers, and thunderstorms. Rainfall is an important part of the water cycle as it provides moisture to the atmosphere and helps to replenish water sources on the ground, such as rivers, lakes, and aquifers. In addition, rainfall plays a significant role in agriculture and can be beneficial or damaging depending on its amount and timing. Rainfall also affects climate, weather, and ecosystems, and can influence the availability of food, water, and other resources.

The organisms that feed on dead and decaying matter are called Saprotrophs.

An organism that feeds on dead and decaying organic matter is called a saprotroph. These organisms are heterotrophic, which means that they obtain their food from other sources. They are important in the ecosystem because they break down dead organic matter and recycle it back into the soil, making nutrients available to other living organisms

Answer:

A. Saprotrophs

Explanation:

Saprotrophs are organisms that obtain their nutrients by feeding on dead and decaying matter. They play a crucial role in the ecosystem by decomposing organic material and recycling nutrients back into the environment.

These organisms secrete enzymes that break down complex organic compounds into simpler substances, such as sugars and amino acids, which they can absorb and utilize for their own growth and energy needs. Examples of saprotrophs include fungi (such as mushrooms and molds) and certain bacteria.

Unlike autotrophs, which can produce their own food through photosynthesis or chemosynthesis, saprotrophs rely on external sources of organic matter for their nutrition. They actively decompose dead plants, animals, and other organic materials, aiding in the process of nutrient recycling and decomposition.

Heterotrophs, on the other hand, are a broader category of organisms that obtain their nutrients by consuming other living or dead organisms. This includes saprotrophs, as well as other types of organisms such as herbivores, carnivores, and omnivores.

Parasites, meanwhile, are organisms that live in or on other organisms, known as hosts, and obtain their nutrients from the host while causing harm or damage to it. Unlike saprotrophs, parasites typically rely on a living host for their sustenance rather than feeding on dead and decaying matter.
