2017 Grade 12 class ም ሆነ ፈተና ዛሬ ስለጨረስን ከዚህ በኋላ ምንም አይነት ምዝገባ እንደማይኖር እናሳውቃለን ። ፈተና እስከምትጨርሱ የሚያስፈልጓችሁን መረጃዎች እና ፋይሎች እያደርስናችሁ እንቆያለን ። ከፈተና በኋላም አዳዲስ መረጃዎችን እናደርሳለን ።

አንድ የ12ኛ ክፍል Natural ተማሪ ሊያውቃቸው የሚገቡ የ Biology ፎርሙላዎች

🎯እናንተ ከእነዚህ ውስጥ ስንቶቹን ይዛችሁአል❓

1. Cell Biology

• Surface Area to Volume Ratio:

SA:V ratio = Surface Area / Volum}

• Mitosis and Meiosis:

• Mitosis produces 2 diploid cells.

• Meiosis produces 4 haploid cells.

2. Photosynthesis

• Photosynthesis Equation:

6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂

3. Cellular Respiration

• Cellular Respiration Equation:

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP

• Net ATP Yield:

• Glycolysis: 2 ATP

• Krebs Cycle: 2 ATP

• Electron Transport Chain: ~34 ATP

• Total: ~36-38 ATP per glucose molecule

4. Ecology

• Population Growth Models:


• Exponential Growth:

N(t) = N₀ eʳᵗ

where N(t) is the population size at time t, N₀ is the initial population size, r is the growth rate, and e is Euler's number.

5.Body Mass Index (BMI)*:


BMI = weight (kg) / (height (m)²}
```

እነዚህን የያዘ ተማሪ በትንሹ ኢንትራንስ ላይ 5 ጥያቄ  ይሰራል ።

📘አንድ የ12ኛ ክፍል ሶሻል ተማሪ ሊያውቃቸው የሚገቡ የ Geography ፎርሙላዎች

1. Population Density

• Formula:

Population Density = Total Population / Total Are}

2. Growth Rate

• Formula:

Growth Rate = Population at End of Period - Population at Start of Period / Population at Start of Perio} × 100

3. Natural Increase Rate (NIR)

• Formula:

NIR = Birth Rate - Death Rate

4. Crude Birth Rate (CBR)

• Formula:

CBR = Number of Live Births in a Year / Total Populatio} × 1000

5. Crude Death Rate (CDR)

• Formula:

CDR = Number of Deaths in a Year / Total Populatio} × 1000

6. Total Fertility Rate (TFR)

• Formula:

TFR = ∑ᵢ₌₁ⁿ Age-specific Fertility Rateᵢ

(Where n is the number of age groups)

7. Net Migration Rate (NMR)

• Formula:

NMR = Net Migration / Total Populatio} × 1000

8. Dependency Ratio

• Formula:

Dependency Ratio = Population Aged <15 + Population Aged >64 / Population Aged 15-6} × 100

9. Life Expectancy

• Concept: Average number of years a person is expected to live based on current mortality rates.

10. Doubling Time

• Rule of 70:

• Formula:

Doubling Time (in years) = 70 / Growth Rate (%}

11. Population Projection

• Formula:

Pₜ = P₀(1 + r)ᵗ

where Pₜ is the future population, P₀ is the current population, r is the growth rate, and t is the time period.

12. Age-Sex Pyramid Analysis

• Concept: Visual representation showing the distribution of various age groups in a population, typically used to understand demographic trends.

📂በጣም ወሳኝ ባዮሎጂ የምስል ጥያቄ በኢንትራንስ ፈተና ሊመጣ የሚችል 👉 parts of Human eye

1. Cornea: The transparent outermost layer that helps to focus light onto the retina.

2. Iris: The colored part of the eye that controls  the amount of light entering the eye.

3. Pupil: The black hole in the center of the iris through which light enters the eye.

4.Lens: A transparent structure behind the iris that helps to further focus.

5. Retina: The innermost layer of the eye that contains photoreceptor cells (rods and cones) w/h detect light.

6. Optic nerve: Transmits the electrical signals from the retina to the brain for visual processing.

7. Sclera: The outer layer and the white part of the eye, helps to maintain the shape of the eyeball.

8. Aqueous humor: A clear fluid that fills the space b/n the cornea and the lens.

9. Vitreous humor: A gel-like substance  between the lens and the retina, helping to maintain the shape of the eye.
