The File System Used by Windows 95

Windows 95 typically uses the FAT16 file system.

Explanation:

• FAT16: The File Allocation Table (FAT) is a file system used by older versions of Windows, including Windows 95. The number 16 refers to the maximum number of bits used to store addresses of data clusters on the hard drive.


• FAT32: While FAT16 was the default file system for Windows 95, it was later replaced by FAT32 in newer versions of Windows, such as Windows 98 and Windows ME. FAT32 allows for larger partition sizes and improved file management.


• NTFS: Windows 95 does not natively support the NTFS file system. NTFS (New Technology File System) was introduced with Windows NT and is used in newer versions of Windows, such as Windows 2000, Windows XP, and beyond. NTFS offers enhanced security, reliability, and support for larger file sizes and volumes.


• LMFS: LMFS is not a file system used by Windows 95 or any other Windows operating system. This option is incorrect.

In summary, the file system typically used by Windows 95 is FAT16.

• Headings make it easier to update or modify specific sections of the report without disrupting the entire document.


• They enhance the overall quality and professionalism of the report.

In conclusion, report headings are essential elements that contribute to the clarity, readability, and organization of a report. They not only improve the document's structure but also assist in effective communication and understanding of the information presented.

Learning is effective in an environment that is emotionally positive and satisfying to learners. Any learner who is emotionally unstable may not be able to learn anything. The teacher must make the environment conducive for students to study and learn efficiently.
Errors made by the students do not indicate that no learning has taken place. Instead, they are the windows through which a teacher can understand the thought process of the students.
Learning is affected by emotional factors at any stage. Emotions change over time as the child matures, and in response to changing environmental interactions. The kind of learning that takes place at different emotional levels also differs.
Learning involves physical, social and emotional activity also.

Acceleration = – 4m/s²; Initial speed, u = 60 m s^-1

Time taken = 5s

Acceleration = change in velocity per unit time

a=v-u/t

v= u + at

v = 60 – 4 x 5 = 40 m/s

Assessment for Learning, also known as formative assessment, is a type of assessment that occurs during the learning process to provide feedback to both the teacher and the student about understanding, progress, and areas needing improvement.

Key Points

• A teacher uses various methods, such as observations, questioning, and informal assessments, to gather information about student understanding during laboratory activities is an example of Assessment for learning.
• Assessment for Learning allows the teacher to identify and address any misconceptions or misunderstandings that may arise during these activities.
• By providing timely feedback and clarification, the teacher helps students develop a deeper understanding of scientific principles.

Hence, we can conclude that the correct answer is Assessment for Learning.

Explanation:
When work is done at a faster rate, the power is increased. This can be understood through the following points:
Definition of Power:
- Power is defined as the rate at which work is done or the amount of work done per unit of time.
- Mathematically, power is calculated as P = W/t, where P is power, W is work, and t is time.
Relationship between Power and Work:
- Power is directly proportional to work.
- When work is done at a faster rate (i.e., completing the same amount of work in less time), the power increases.
- Conversely, if work is done at a slower rate (i.e., completing the same amount of work in more time), the power decreases.
Implications:
- If work is done at a faster rate, it means that more power is being exerted.
- This could be achieved by either applying a greater force or by completing the work in less time.
Therefore, the correct answer is option A: power is more.

 A colloid is a heterogeneous mixture whose particles are not as small as solution but they are so small that cannot be seen by naked eye. When a beam of light is passed through a colloid then the path of the light becomes visible. For example milk, smoke etc.

Breeder hen diets should be supplemented with Vitamin K to ensure good chick health. Laying hens fed a diet deficient in vitamin k produce eggs low in the vitamin, and when the eggs are incubated, the chicks produced have low reserves and a prolonged clotting time. Vitamin A  is easily destroyed in feed processing and storage. Usually, 10,000-15, 000 IU/ kg vitamin A is supplemented in broiler or broiler breeder commercial feed. High levels of vitamin A decreased egg production, size, and hatchability in laying hens.

Lysosomes are called the "suicide bags" of the cell because their enzymes can break down cellular components, and in certain conditions, they can lead to the digestion of the cell itself.

Insulin is a hormone produced by the pancreas that plays a vital role in regulating blood sugar levels. It helps cells in the body absorb glucose from the bloodstream, thereby lowering blood sugar levels. Imbalances in insulin production or function can lead to conditions like diabetes mellitus.

Tendons are, in fact, fibrous tissues that connect muscles to bones. They are strong and dense, providing a mechanism for muscle contraction to move bones. Describing tendons as non-fibrous and fragile is inaccurate.

Function of an ecosystem involves:
The function of an ecosystem is a complex process that involves various components working together to sustain life. The main functions of an ecosystem include:
1. Energy flow:
- Ecosystems are powered by the flow of energy through food chains and food webs.
- Producers (plants) convert sunlight into chemical energy through photosynthesis.
- Consumers obtain energy by consuming other organisms.
- Decomposers break down organic matter and release energy.
2. Nutrient movement:
- Nutrients are essential for the growth and development of organisms in an ecosystem.
- Nutrients are cycled through biogeochemical cycles, such as the carbon, nitrogen, and phosphorus cycles.
- Producers take up nutrients from the environment and incorporate them into their tissues.
- Consumers obtain nutrients by consuming other organisms.
- Decomposers break down organic matter and release nutrients back into the environment.
3. Interactions and relationships:
- Ecosystems are composed of numerous species that interact with each other.
- Predation, competition, symbiosis, and mutualism are common interactions in an ecosystem.
- These interactions help maintain the balance and stability of the ecosystem.
4. Ecological services:
- Ecosystems provide numerous benefits to humans and other organisms.
- They regulate climate, purify air and water, and provide habitats for various species.
- Ecosystems also provide resources such as food, timber, and medicines.
5. Biodiversity conservation:
- Ecosystems support a wide range of species, each with its own role and contribution.
- Conserving ecosystems is crucial for maintaining biodiversity and preventing species extinction.
In conclusion, the function of an ecosystem involves energy flow, nutrient movement, interactions and relationships, ecological services, and biodiversity conservation. These functions are interconnected and essential for the sustainability of life on Earth.
