1. What are the different properties of light that apply to the image formation of
optical devices such as mirrors and lenses?
Answer:
Optical instruments are based on optics. They use mirrors and lenses to reflect and refract light and form images. The light microscope and telescope use convex lenses and mirrors to make enlarged images of very tiny or distant objects. A camera uses a convex lens to make a reduced image of an object.
The property of light that is important to the image formation in mirrors is reflection. The property of light that is important in the formation of an image by lenses is refraction.
Light refers more specifically to the portion of the electromagnetic spectrum that is perceivable with the optical eyes. There are several properties of light such as reflection, refraction, diffraction, interference, etc.
The property of light that is important to the image formation in mirrors is reflection. The property of light that is important in the formation of an image by lenses is refraction.

Why is the use of electron microscopy important in studying cells ??
Explanation:
Electronic microscope helps us to see each every part of the cell. So, it is considered important
Answer:
A cell is the smallest unit of life. Most cells are so small that they cannot be viewed with the naked eye. Therefore, scientists must use microscopes to study cells. Electron microscopes provide higher magnification, higher resolution, and more detail than light microscopes.

Examining different cells such as the plants, animal, and fungus cells. Identify the different organelles found in different cells and list the organelles and structures the characterize each of them.
Answer: Organelle is a sub-unit of cell and it is involved in performing specialized function within the cell. The type of organelles vary from organisms to organisms.
Explanation:
1. Centrioles are the cell organelles in which the spindle fibers are organized to which the chromosomes attach and mitotic division takes place. These are present only in animals and they are absent in plant and fungal cells.
2. Vacuoles are the storage organelles which store excess water, waste metabolites, sugars and other components in them. In plant cells they are of larger size whereas the vacuoles are small in size in case of the animal and fungal cells.
3. The plants cells and fungal cells have cell wall made up of cellulose (plants) and chitin (fungus) respectively. The cell wall is absent in animal cells.
4. The plant cells and fungal cells do not possess cilia and flagella for locomotion whereas animal cells have cilia and flagella.
What are the answers for questions 4 and 5?
Answer:
4. D (enzymes 1 and 3 works equally well in an acidic and alkaline environment respectively)
5. C. 2; 7; 9.5
Explanation:
The image attached to this question shows a graphical representation of the pH ranges for three enzymes. According to the image;
- Enzyme 1 reached its peak reaction rate at pH 2 (acidic)
- Enzyme 2 reached its peak reaction rate at pH 7 (neutral)
- Enzyme 3 reached its peak reaction rate at pH 9.5 (basic)
This result means that enzymes 1, 2 and 3 will work well and effectively at an acidic, neutral and alkaline environment respectively. Likewise, the optimal pH level for enzymes 1, 2 and 3 are 2; 7; and 9.5 respectively.
How would Earth be different without the greenhouse effect?(1 point)
A.There would be more solar energy reaching Earth.
B.The atmosphere would contain more methane.
C.The oceans would contain more carbonic acid.
D.There would be more ice on Earth's surface.
Answer:
I think the answer will be:
D. There would be more ice on Earth's surface.
Explanation:
Without the greenhouse effect, the Earth would have an average temperature of -18°c and life would not be able to survive.
The Earth would be different if the greenhouse gasses didn't even exist.
The Earth's surface would be covered in more ice.
So, option D. is correct.
Define greenhouse effect.The greenhouse effect happens when solar energy passes through a planetary system and heats its surface, but the air prevents the energy from going directly to space, leading in a warming climate.
The Earth would be different if the greenhouse gasses didn't even exist.
The Earth's surface would be covered in more ice. So, option D. is correct.

What are the main characteristic for changing an organism?The kingdom is a smaller taxon than the recently added domain, which is a more expansive taxon. Similarities in outward physical characteristics serve as the foundation for the Linnaeus system.
Gene variants, sometimes known as mutations, can cause genetic differences, or a normal process in which genetic information is rearranged as a cell prepares to divide can also cause genetic variations (known as genetic recombination).
Therefore, Different phenotypes can be introduced into an organism by genetic changes that change gene activity or protein function.

Why do you think it's important for scientists to study plate tectonics? Explain.
Studying plate tectonics is important because it helps explain Earth's surface features, predict natural disasters, investigate Earth's history, explore natural resources, and understand global climate patterns. It is a multidisciplinary field that provides valuable insights into the dynamic nature of our planet.
Scientists study plate tectonics for several important reasons. Firstly, understanding plate tectonics helps scientists explain the formation of different features on Earth's surface, such as mountains, valleys, and ocean basins. By studying the movement and interactions of Earth's tectonic plates, scientists can better understand the processes that shape our planet.
Secondly, studying plate tectonics is crucial for predicting and understanding natural disasters. Earthquakes, volcanic eruptions, and tsunamis are all related to tectonic activity. By analyzing plate boundaries and identifying areas prone to seismic activity, scientists can provide early warnings and help communities prepare for potential disasters.
Furthermore, studying plate tectonics is essential for investigating Earth's history. The movement of tectonic plates over millions of years has shaped the continents and influenced the evolution of life on our planet. By examining the distribution of fossils and rock formations, scientists can reconstruct past tectonic events and gain insights into Earth's geological history.
Additionally, understanding plate tectonics is crucial for exploring natural resources. Many valuable minerals and energy resources are formed as a result of tectonic processes. By studying plate boundaries and their associated geological features, scientists can identify potential locations for mining and resource extraction.
Lastly, studying plate tectonics contributes to our understanding of global climate patterns. The movement of tectonic plates affects ocean currents, weather patterns, and the distribution of landmasses. By analyzing these interactions, scientists can better predict and understand climate change.

Consider two individuals that have the following genotypes: CCDd and Ccdd.
Predict the outcomes of a cross for these two individuals. What are the outcomes that could occur in the offspring? Select ALL that
apply.
A)
1/4 of the offspring will be CCdd.
B)
ccdd is not possible as an outcome of this cross,
All of the offspring will show the dominant trait for the allele.
D)
Only half of the offspring will show the dominant trait for the Dallele.
E)
All of the offspring will be heterozygous and will display the dominant
traits
Answer:
A,B,C,D
Explanation:
Since one parent is CC, there is no way to get cc as an outcome from this cross. However, there is also no way that all of the offspring will be CcDd, which is heterozygous for both traits. Therefore, this is the only answer choice that is incorrect.
As per observation about the two individuals that have the following genotypes: CCDd and Ccdd the cross are options: a,b,c,d.
Since one parent is CC, there may be no manner to get cc as an final results from this cross. However, there may be additionally no manner that every one of the offspring could be CcDd, that is impure breed for each traits.
