Answer:

Ratio = 3\times 10^5

Explanation:

Side of a cube, a = 20 µm

a=20\times 10^{-6}\ m

The surface area of a cube, A = 6a² (a is side of the cube)

The volume of a cube, V = a³

The ratio of the surface to volume ratio of the cell will be given by :

R=\dfrac{6a^2}{a^3}\\\\R=\dfrac{6}{a}\\\\R=\dfrac{6}{20\times 10^{-6}}\\\\R=3\times 10^5

So, the ratio of the surface to volume ratio of the cell 3\times 10^5.

Community ecologists study the factors that determine the abundance of different species. The Abundance of three algae species (
Tema [17]

Answer:

Explanation:

Given that:

The abundance of three algal species in Lake A is now represented by the vectors:

[97, 84, 43] and [100, 80, 50]

Now if we look at Lake A, the change occurring in the vector of algae species can be determined as:

a = [100 -97, 80 - 84. 50 - 43]

a = [3, -4, 7]

Thus, the magnitude of that change is:

|a| = \sqrt{(3)^2 +(-4)^2+(7)^2}

|a| = \sqrt{9+16+49}

|a| = \sqrt{74}

|a| =8.6 \ mg/mL

The abundance of three algal species in Lake B is now represented by the vectors:

[25, 59, 22] and [20, 63, 15]

At Lake B, the change occurring in the vector of algae species can be determined as:

b = [20 -23, 63 - 59. 15 - 22]

b = [-3, -4, -7]

Thus, the magnitude of that change is:

|b| = \sqrt{(-3)^2 +(4)^2+(-7)^2}

|b| = \sqrt{9+16+49}

|b| = \sqrt{74}

|b| =8.6 \ mg/mL

Hence, for both Lake A and B, the magnitude of change is the same.

Short definition of amoeba​
Dimas [21]
Amoeba: Also ameba. A single-celled (protozoan) organism that constantly changes shape. The word "ameba" is from the Greek "amoibe" meaning "change." Ameba can infect the bowels to cause diarrhea and the liver to cause abscess formation. Here is more information. The definition of an amoeba is a one-celled organism, common in water and soil, possessing no set cell organs, structure, or defining shape. An example of an amoeba is an invisible organism called Entamueba histolytica which is found in tropical areas that are unclean, and causes the deadly disease dysentery. Hope this helps! Mark brainly please!

ad-work [718]

Answer:

The correct answer is option A) "+/+".

Explanation:

Cellulose-digesting organisms in the gut of a termite and the termite itself have a positive interaction among them. The interaction among these organisms is classified as a symbiotic interaction because both organisms are benefited from it. Cellulose-digesting organisms in the gut of a termite obtain food and protection from the termite, and in return the termite is able to digest the cellulose of wood, its main source of food.
