3.4.3 Lab: Why are cells so small?

Answers

Answer 1

Answer: The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. ... That is why cells are so small.

Explanation: because they can absorb nutrients much more efficiently. Because they are smaller they can efficiently absorb enough food. ... When a cell doubles in size the volume increases much more then the surface area, which is why large cells cannot receive enough food efficiently for their volume. Cells are small because they are more efficient as smaller entities. Information within small cells is transmitted more quickly and efficiently than within larger cells. ... Thus a higher cell surface area-to-volume ratio, i.e., smaller cell size, is desired for most efficient cellular activity.

Answer 2

The cells are so small because their small size allows them to take in food and get rid of the waste.

The cells are the basic structural and functional unit of all organisms on earth except the Viruses. The size of the cell is so little it allows the organism to maximize the ration of surface area to volume. Smaller cells are expected to have greater ratio which promotes more molecules as well as ions to move across the plasma membrane.The small size of the cell facilitate to get the nutrients inside the cell and waste outside the cell quickly. Hence, small size of cell facilitates to get food inside and get rid of waste.

What do you mean by adaptation?

In biology, adaptation has three related meanings. It is the dynamic evolutionary process of natural selection that fits organisms to their environment, enhancing their evolutionary fitness. Secondly, it is a state reached by the population during that process.

The ability of living organisms to adjust themselves to their surroundings is called adaptation. Adaptations are the changes in structure or behaviour of an organism that will allow the organism to survive in that habitat.

Adaptations are unique characteristics that allow animals to survive in their environment. There are three types of adaptations: structural, physiological, and behavioral.

The four steps that a scientist uses to solve a problem are creating hypothesis, experiment, data sorting and writing conclusion.

What are hypothesis?

A hypothesis is an elaboration posited for a characteristic. The scientific technique requires that a hypothesis be testable in order for it to be considered a scientific hypothesis.

Scientists typically base scientific hypotheses on previous findings that cannot be adequately explained by existing scientific theories.

Any process that co-ordinate system data into some defined order to make it simpler to understand, analyze, or visualize is referred to as data sorting.

The conclusion is the final section of an academic essay. The conclusion should restate your response to the question and briefly summarize key points. It does not contain any new points or information.

A scientist solves a problem by developing a hypothesis, conducting an experiment, sorting data, and writing a conclusion.

Thus, by using these steps, scientist can come to an end for the problem.

Desert plants and animals are adapted to the lack of what and high

Answers

The two main adaptations that desert animals must make are how to deal with lack of water and how to deal with extremes in temperature. Many desert animals avoid the heat of the desert by simply staying out of it as much as possible

Answer:

lack of water and high concentration of heat and dryness

Explanation:

Deserts don't get that much rainfall, so desert wildlife are adapted to survive in such a dry climate. Take the camel, for instance, it can store three bathtubs of water in it's hump, so it can go a very long time without water. And without that rainfall, the desert is dry and, usually, very hot. Animals have adapted to this by only coming out in the nighttime when it's cooler.

bacteria.

Which two structures would the scientist most likely see?PLEASE EXPLAIN WHY

A:nucleus and DNA
B:DNA and cell wall
C:cell wall and vacuole
D:vacuole and nucleus

Answers

Answer:

The two structures most likely to be observed by the scientist when looking at a type of bacteria under the microscope are cell wall and vacuole (option C).

Explanation:

Bacteria are prokaryotic organisms that lack a nucleus, most of the organelles, and whose DNA is dispersed in the cytoplasm. Some types of bacteria have a plasma membrane surrounded by a cell wall, and may be equipped with vacuoles to perform their functions.

It is very likely that two structures that are most likely to be differentiated when a type of bacteria is observed under the microscope are the cell wall and the vacuole, according with information above.

The other options are not correct because:

    A and D. Bacteria lack a nucleus.

    A and B. Bacterial DNA is dispersed in the cytoplasm and is very difficult to observe under the microscope.

cell wall vacuole
