A plant's photoperiod is the amount of time each day that the plant receives sunlight. A plant with a 12L:12D photoperiod receives 12 hours of light and 12 hours of dark per day. A researcher investigated whether photoperiod affects the development of flower buds in chrysanthemums, a type of flowering plant. She maintained three samples of chrysanthemums that did not initially have any flower buds under different photoperiods. After two weeks, the researcher recorded the presence or absence of flower buds in each sample. The researcher's results are shown in the table. Sample Photoperiod Results 1 13L:11D fully developed flower buds formed on all plants 2 14L:10D partly developed flower buds formed on some plants 3 15L:9D no buds formed on any plant Which statement is best supported by the researcher's findings?

Select all statements that are true. 1) By selecting the genetic information that is passed on to future generations, genetic engineering is similar to natural selection. 2) Unlike natural selection, genetic engineering selects the organisms most beneficial to the environment. 3) By selecting the genetic information that is passed on to future generations, genetic engineering can happen at a different rate than natural selection. 4) Like natural selection, genetic engineering may be used on all organisms, including humans. 5) The effects of genetic engineering apply only to the organism selected, but natural selection affects the entire population.

Bacteria are prokaryotic cells. By contrast, animal, plant, and fungal cells are eukaryotic What is the main difference between prokaryotes and eukaryotes?

Answers

Answer:

I think the answer is that prokaryotes have a nucleus and eukaryotes do not.

Explanation:

It is the first thing I think of when I think of a difference between the two.

Final answer:

Prokaryotic cells, like bacteria, are simpler, smaller, and do not have a nucleus or other membrane-bound organelles. Their genetic material is loosely housed in the cell. On the contrary, eukaryotic cells, like those of animals, plants, and fungi, have a nucleus, more complex structure, and contain various defined organelles.

Explanation:

The main difference between prokaryotes and eukaryotes lies in the cellular structure. Prokaryotic cells, like bacteria, are simpler and smaller than eukaryotic cells. They do not have a nucleus or other membrane-bound organelles. Instead, their genetic material is loosely housed in the nucleoid, a region within the cell.

On the other hand, eukaryotic cells, such as those of animals, plants, and fungi, have a more complex structure. They are larger and contain a nucleus where the cell's genetic material is stored. Eukaryotic cells also contain various other defined organelles, like mitochondria, endoplasmic reticulum, and Golgi bodies, that carry out different functions.

Unnatural occurrences can have the most significant impact on an ecosystem. True

Answers

Answer: True

Explanation:

Unnatural occurences are those catastrophic events induced by humans which can exert drastic impact over the ecosystem. These may include deforestation, forest fire, intentional explosion, and others. This will result in loss of many species due to damage caused to the non-living physical environment.

If your question is true or false, my answer is True. 
Because any unnatural occurrences like building houses can change the ecosystem a lot. 
When we build a house we are destroying some animals house.

What is a limitation of using electron microscopes to view specimens? (2 points)

Answers

Answer:

The electron microscope uses electrons to form images for this reason does not allow to observe living cells because they need to work in a high vacuum atmosphere, the samples require preparation through a long fixation process, which means that it is not possible to observe living cells. To observe a cell with this microscope, dead cells must be observed, after being fixed and stained with heavy metal ions.

In these microscopes it is not possible to observe the cells carrying out their normal behaviors (for example, migrating or dividing) under the microscope

The correct answer is C. You cannot view live specimens because the necessary preparation kills cells. 

The answer is pretty self-explanatory. Unlike it, regular microscopes can view living creatures such as bacteria or similar.

How do organisms store and use energy?

Answers


Plants store energy in form of starch usually in the roots and/or stem. When there is need for energy such in respiration, starch is converted to glucose which is then used to fuel the process of cellular respiration.

In animals, energy is stored in form of glycogen in the liver and muscle tissues. When there is demand for energy, glycogen is converted back to glucose, which is taken in by the cells and used to fuel cellular respiration

In both plant and animal cells, the purpose of respiration is production of ATP (or adenosine triphosphate), which is the form of energy that cells use.
