Transpiration occurs when plants release water vapor.
True or False?
Answer:
true
Explanation:
Answer:
false Explanation: The water eventually is released to the atmosphere as vapor via the plant's stomata tiny, closeable, pore-like structures on the surfaces of leaves. overall this uptake of water at the roots, transport of water through plant issues, and releases of vapor by leaves is known as transpiration.

The ringing of a telephone prompts to answer a call.
Explanation:
The sensory neurons found in the receptor organ ( which is the ear ) will detect the ringing of the telephone, and will therefore transmit a nervous message to the central nervous system .The brain interprets the nervous message , and then sends a message through the motor neurons to the effector organ , which in turn will respond by answering the call .

What's the main reason why cell specialization is important?
Question 12 options:
It allows multicellular organisms to perform many distinct functions.
It allows unicellular organisms to perform many distinct functions.
It generates totipotent cells.
It creates cells at a faster rate.
Answer:
It allows multicellular organisms to perform many distinct functions.
Explanation:
Cell specialization is important primarily because it allows multicellular organisms to perform many distinct functions. Cell specialization isn’t important in unicellular organisms, because it doesn’t occur. Cell specialization isn’t important primarily for creating cells faster, and it doesn’t generate totipotent cells. Rather, totipotent cells are the stem cell progenitors that allow cell specialization to occur.
It makes it possible for multicellular creatures to carry out a wide variety of unique roles. Therefore, option (A) is correct.
What is cell specialization?The transformation of a stem cell into a differentiated cell type is accomplished by a process known as cellular differentiation. Typically, the cell will transform into a type that is more specialized.
The primary reason why cellular specialization is so important is that it enables multicellular organisms to carry out a wide variety of diverse jobs. Because it does not take place in unicellular creatures, the process of cell specialization is irrelevant to their biology. The primary reason why cell specialization is not crucial is that it does not produce totipotent cells, nor does it speed up the process of making new cells. Instead, totipotent cells are the progenitors of stem cells, which are the cells that can differentiate into specialized cell types.

Why do countries not convert from the use of oil to solar energy?
Solar energy is more difficult to use than oil to make electricity.
It requires more work to use solar energy to make electricity.
Solar energy is a limited resource.
It is more expensive to create solar energy than use oil for making electricity.
Answer:
It is more expensive to create solar energy than use oil for making electricity.
Explanation:
Solar energy is a renewable source of energy from the sun. It is the most powerful and eco-friendly source of energy, however, many countries still do not use this source of energy in creating electricity. This is because the technology behind using solar energy to create electricity is very expensive in comparison with the use of oil.
In as much as solar energy is always readily available everywhere and everyday (natural), building the technology to make it generate electricity is huge. Hence, countries stick to the use of oil, which is way cheaper to operate.

If plant sap has as much sugar as a can of soda, do you think that if you bit into a plant’s leaves or stems, would it taste sweet? Why or why not?
Answer:
No
Explanation:
If plant sap has as much sugar as a can of soda, they will not taste sweet if one bit into their stems of leaves.
This is because most plants do not store sugar, which is the product of photosynthesis, in leaves or stems. The few ones that store their photosynthetic products in leaves/stems do not store them directly as sweet sugar. They often stored them as starch which is not generally sweet in taste.
Hence, plant's leaves/stems will not taste sweet even if they have as much sugar as a can of soda.

Explanation:
On April 20, 2010, an explosion on the Deepwater Horizon Macondo oil well drilling platform released 4 million barrels (636,000 cubic meters) of oil into the Gulf of Mexico. It took scientists and engineers nearly three months and several different attempts to cap the well. The Macondo oil well was located 1524 m (5000 feet) below the surface of the water, about 80 km (50 miles) off the coast of Louisiana. The spill affected 2113 km (1300 miles) of shoreline along the coasts of five states. Most crude oil contains 84–87% carbon by weight. Scientists have not yet fully assessed the environmental impact of the accident.
