Which best describes the importance of mitosis to living organisms?

Answers

Answer:

The correct answer is - growth and development.

Explanation:

Mitosis is one of the cell division cycles that occurs in the somatic cells. It is characterized by producing the two daughter cells by dividing one parent cell which is an exact copy and the same number of chromosomes.

The major importance of mitosis in the life cycle of an organism is growth and development by producing more cells and rapid in numbers. The cells divide in the mitosis for the major purpose of tissue repair and growth of organisms.

Thus, the correct answer is - growth and development.

Mitosis can help by reproducing that living organism quickly and by multiple times.

In which sealed container would the organisms be able to continuously cycle O2 and CO2 gases?A. A terrarium with mice and wood shavings
B. An aquarium with fish and plastic plants
C. An aquarium with water plants and a snail
D. A terrarium with a frog and a pool of water

Answers

The correct answer is C.
In the aquarium, the water plants would provide the O2 molecules necessary for the snail's metabolism and the snail would release the CO2 molecules that are a byproduct of his metabolism into the container. The CO2 would later be used by plants to make sugar in the process of photosynthesis, releasing more O2 and the cycle of two gases would be completed.

Answer:

The correct answer is C. An aquarium with water plants and a snail

Explanation:

In an aquarium with water plants and snail the flow of oxygen and carbon dioxide will be continuous because plants are able to do photosynthesis which release the oxygen as the byproduct and this oxygen will be used by snail and snail during respiration release CO2 which will be used by plants in the process of photosynthesis to make food for itself.

Therefore there will be symbiotic relationship between plants and snail because snail provides carbon dioxide to plant and plant provide oxygen to the snail and support their survival. Therefore in this container organism would be able to continuously cycle O2 and CO2. So the right answer is C.

Which of the following cell organelles do both prokaryotic and eukaryotic cells have?A. Golgi apparatus

B. ribosomes

C. mitochondria

Answers

Answer:

Option B, Ribosomes

Explanation:

Ribosome exists in both free state and also as a membrane bound organelle. Thus, ribosomes is found in both the eukaryotic and prokaryotic cells as it is an essential component that facilitates the translation of RNA and formation of protein.

Golgi apparatus and mitochondria are membrane-bound organelles and all membrane-bound organelles are found in eukaryotes only. Prokaryotes do not have membrane-bound organelles

Thus, option B is correct

They both have ribosomes, so the answer is B.

Phosphorescence is a phenomenon associated with which algal division

Answers

Phosphorescenceis related to fluorescence in that the phosphorescent does not re-emit theradiation it absorbs. It is a process in which the absorbed energy of asubstance is released relatively slowly inn the form of light. One example ofthis is the glow in the dark stick. The stick will glow even brighter if it isexposed in a light material. Another example that is a phosphorescentassociated in algal division are the Pyrocystis fusiformis. They are dinoflagellatesand can glow brighter at lighter conditions

Answer:

Dinoflagellates

Explanation:

Scientists who rely on creativity also tend to be persistent when they pursue a research goal. How might persistence be an advantage for a creative scientist?

Answers

Creative persistence is often useful when one is designing an experimental paradigm for example. It is useful tweaking different parameters of an idea which is much easier when one is creative - this is also at the core of scientific research very often.
