Explanation:
Plant cell:
It is found only in plants.
It consists of cell wall.
Animal cell:
It is found only in animals.
It does not consists of cell wall.
Answer:
The main structural differences between plant and animal cells are the additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles.
Chloroplasts
In animal cells, the mitochondria produces the majority of the cells energy from food. Plant cells use sunlight as their energy source; the sunlight must be converted into energy in a process called photosynthesis. Chloroplasts are perform this function. The energy conversion in plants is a complex set of reactions similar to those performed by mitochondria in animals
The Cell Wall
Another structural difference between in plant cells is the presence of a rigid cell wall surrounding the cell membrane. The tough wall gives added stability and protection to the plant cell. If you think about it, most animal cells are inside an organism that has either an exoskeleton or an endoskeleton, built in structure. Plants don't have a skeleton of any kind so the cells have to perform this.
Vacuoles
Vacuoles are large, liquid-filled organelles found only in plant cells. Vacuoles can occupy up to 90% of a cell's volume and have a single membrane. Their main function is as a space-filler in the cell, but they can also fill digestive functions and their interiors can be used as storage for nutrients.
Both plant and animal cells comprise membrane-bound organelles, such as endoplasmic reticulum, mitochondria, the nucleus, Golgi apparatus, peroxisomes, lysosomes. They also have similar membranes, such as cytoskeletal elements and cytosol. The plant cell can also be larger than the animal cell. The normal range of the animal cell varies from about 10 – 30 micrometres and that of plant cell range between 10 – 100 micrometres.

7 Infer Before scientists were able an to view and study the ocean floor directly , why might they have expected the ocean floor to be smooth and flat ?
Answer:
Rocks deteriorating the ocean floor
Explanation:
As rocks scrape past the ocean floor they chip away at it smoothing it (erosion) out but due to continental drift and magma rising and cooling it causes the new igneous rock forms on the ocean floor making it rough and rugged.
When thinking about this think about a pebble on the beach, what it is?
rounded due to erosion just as scientists thought the ocean floor would be.

A botanist discovers a new plant species in the Amazon rain forest that has blue leaves. Briefly explain what can be inferred about the pigments in the leaves of this plant and the wavelength they absorb
The observation of a new plant species in the Amazon rainforest that has blue leaves can be interpreted as a plant that absorbs all color wavelengths except blue.
What is photosynthesis?Photosynthesis is a group of reactions through which plants can produce simple carbohydrates by using the energy from the sun.
During this process (Photosynthesis), the plant needs to absorb solar radiation in different color wavelengths.
The observation of blue leaves means that the plant cannot absorb this color wavelength during Photosynthesis.

Why is it important that people use fewer non-renewable resources and more renewable resources?
Your Opinion and Evidence
Answer:
well I think that it I'd important to use more renewable resource because using much of non renewable sources can cause a shortage of it. it is non renewable
Answer:
Harnessing renewable resources tends to be better for the environment. Non-renewable resources such as fossil fuels produce vast amounts of greenhouse gasses when they are burnt and this contributes to acid rain, climate change and other ecologically harmful effects. By contrast, wind and solar energy do not produce these dangerous gases.

A biologist is studying golden frogs that live in cool streams running through the rain forests of Central America. The biologist conducts a survey of the population and counts over 100 frogs in one mile of stream. The biologist returns to the same location one year later and counts only 20 frogs in that same stretch of stream. The biologist wonders why there are suddenly so few golden frogs.
The biologist also observes that a mining company has set up a copper mine only a few miles from the stream. By reading studies on copper mining operations in other parts of the world, the biologist learns that the wastewater runoff from the mines is highly acidic and contains potentially toxic compounds.
Which question most closely relates to the biologist's observations and collected data?
Are the golden frogs succumbing to a fungal infection?
Answer:
are the frogs dying off because of the mines waste water?

The Coriolis Effect shows us that when moving from the equator towards the poles, the air is moving slower than the ground below it. So, the correct option is A.
What is Coriolis Effect?The French mathematician & physicist Gaspard-Gustave de Coriolis is honoured with the name "Coriolis Effect." It has an impact on everything from ocean currents to weather patterns to aviation transport. Despite how significant the Coriolis Effect is, few people are aware of it and even fewer actually comprehend it.
Circulating air gets deflected to the right throughout the Northern Hemisphere as well as to the left inside the Southern Hemisphere as a result of the Earth's axis of rotation. The Coriolis effect is the name given to this deflection. The Coriolis Effect demonstrates that the air moves more slowly than the ground underneath it as it travels from the equator to the poles.
Therefore, the correct option is A.
