Survival on land for organisms is difficult because of the problem of.

Biology
1 answer:
Alex787 [66]2 years ago
7 0

Answer: Relatively less abundant water on land makes survival difficult for terrestrial animals. All four problems stem from a lack of water. Terrestrial animals spend energy looking for water, which is not available easily. Terrestrial temperature fluctuates widely, so energy investments have to be made to keep body temperatures regulated.

A molecular compound which dissolves in water and doesn't form ions in solution (not ionized).
ad-work [718]

c. C2H5OH

A common example of a nonelectrolyte is glucose, or C6H12O6. Glucose (sugar) readily dissolves in water, but because it does not dissociate into ions in solution, it is considered a nonelectrolyte; solutions containing glucose do not, therefore, conduct electricity.

Eukaryotic cells have a true nucleus, which means the cell's DNA is surrounded by a membrane. Therefore, the nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis. ... In eukaryotes, chromosomes are linear structures.

Living organisms are only able to function and thrive if they can maintain constant or stable internal conditions. This ability
Hatshy [7]
The ability of organisms to regulate and thus maintain a relatively stable internal environment, despite external pressures, is called HOMEOSTASIS. This word comes from two Latin/Greek root words: "homeo" and "stasis".
"Homeo" means constant or unchanging. And "stasis" or "static" refers to stillness, non-movement. So, together, we can translate Homeostasis into a constant stillness inside, which makes sense for "maintaining normal internal states."

Which value is being measured in the columns labeled fraction remaining and percentage remaining
ahrayia [7]

<u>Question</u>:

Which value is being measured in the columns labeled "Fraction remaining” and "Percentage remaining”?

  1. years of decay
  2. quantity of energy
  3. number of stable atoms
  4. amount of material that has not decayed

<u>Answer</u>:

"Amount of material that has not decayed" being measured in the columns labelled "Fraction remaining” and "Percentage remaining”

<u>Explanation</u>:

The table shown below having explains about the half life , the  amount of sample in both fraction and percentage. The first column named half life elapsed tells  us the the number of half life that that is completed. Half life is the time taken for an element to reduce or decay into half of its initial amount.

The fraction remaining column gives the amount of sample that is left behind  after the half life particular number of half life has completed.  similarly the percentage remaining column gives the amount of sample in percentage. For example, the 5th row tells us that after 4 half life is over \frac{1}{16} th of the sample remained. In percentage it is 6.25%
