Answer:
Explanation:
At least 136 wolves were killed in the park between 1914 and 1926. By the 1940’s wolf packs were
seldom reported in the park. In fact, by the mid-1900’s wolves had been nearly eliminated not just from
Yellowstone but from the lower 48 states entirely.
Reintroduction was not without controversy as there were, and still are, many stakeholders involved in the
Yellowstone area, each with unique concerns. However, in the twenty years since the reintroduction of the
wolves, scientists have noticed many positive changes to the park ecosystem. This set of activities seeks to
introduce students to the trophic cascade that has occurred in the park and the positive changes in the
ecosystem since the reintroduction of a top predator – the wolf.

Answer:
size and amount of yolk
Explanation:
The main difference between the eggs of a frog, bird and mammals is their size. The size of frog egg is small as compared to bird and mammals. Egg laying mammals have bigger egg . The similarities between eggs of frog, bird and egg laying mammals is the high amount of yolk in the egg which is used as a source of food by the embryo that is present inside the egg during the developmental stages.
An animal cell containing 0.1M of NaCl is placed in a beaker full of 4.3M NaCl. The solution the cell is placed in is called: hypertonic, hypotonic, isotonic
The solution that the animal cell is placed in is called hypertonic.
Hypertonic solution refers to a solution with a higher concentration of solutes compared to another solution. In this case, the beaker full of 4.3M NaCl has a higher concentration of solutes compared to the 0.1M NaCl in the animal cell.
As a result, water molecules will move out of the cell in an attempt to balance the concentration of solutes on both sides of the cell membrane. This can cause the cell to shrink or undergo plasmolysis.

. What sorts of living things are made up of prokaryotic cells?
Bacteria and archaea are the two types of living beings made up of prokaryotic cells.
What are bacteria and archaea?Bacteria and archaea are both prokaryotic and unicellular organisms. This means that they both lack a true nucleus and membrane-bound organelles. The genetic material is present in a long single loop of chromosome, called the nucleoid.
Both bacteria and archaea have a cell wall present outside of the cell membrane. The structural composition of the cell wall is different among them. In bacteria, the cell wall is made up of peptidoglycan (a sugar and protein complex compound) and in archaea, it is made of pure polysaccharides.
Both of these organisms reproduce asexually. They also have flagella for locomotion, pilus for adherence and a capsule outside of the cell wall for protection against conditions like dehydration.
Therefore, bacteria and archaea are living beings made up of prokaryotic cells.

What are the stages of bee development (eggs,larvae,pupae)
The stages of bee development are egg, larva, pupa, and adult. Eggs hatch into larvae, which then transform into pupae. Finally, adult bees emerge and undergo further maturation.
The stages of bee development are:
1. Egg: The bee life cycle begins when the queen bee lays an egg in a honeycomb cell.
2. Larva: The egg hatches into a larva, which is a legless, grub-like creature. The larva is fed a special diet called royal jelly, which stimulates its growth.
3. Pupa: The larva undergoes metamorphosis and transforms into a pupa. Inside the sealed cell, the pupa undergoes various changes, developing into an adult bee.
4. Adult Bee: After completing the pupal stage, the fully developed adult bee emerges from the cell. The bee then undergoes further maturation, such as its exoskeleton hardening, wings expanding, and adult coloration appearing.
It's important to note that there are three castes of bees: queen, worker, and drone. The development process for each caste is similar, but the diet and size of the cells they are raised in differ, leading to their distinct roles within the colony.

reasons why science teachers think practical sciences is a good thing.
rubric
identify reasons 4 marks
explanation and practical example 16 marks
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.
