Question

LESSON 5: bio 1A Cells and homeostasis

#1 which of the following are factors that both unicellular and multicellular organisms actively balance in order to achieve homeosis?

A.) size, shape, and mass

B.) texture, density, and flexibility

C.) wastes, nutrients, and water (CORRECT)

D.) sound, light, and temperature


#2. what would be the outcome of a unicellular organisms that can not maintain homeostasis?

A.) it dies (CORRECT)

B.) it divides

C.) it shrinks

D.) it grows larger

#3 which of the following statements are true?

A.) both unicellular and multicellular organisms are at risk of having too much water entering their cells if they are exposed to water containing no salts (CORRECT)

B.) only multicellular organisms have structures that enable them to regulate excess water entering their cells

C.) unicellular organisms can protect themselves against too much water uptake by closing their membrane channels that allows water transport

D.) unicellular organisms, but not multicellular organism, must deal with the movement of water by osmosis across their cell membranes

#4. how are cells in a multicellular organisms able to achieve homeostasis?

A.). they are uniform in function at work independently from one another

B.). they are specialized in function and work independently from one another

C.). they are uniform in function and work cooperatively with one another

D.) they are specialized in function and work cooperatively with one another (CORRECT)

Answer 1

Is this actually a question? Lol.

Answer 2

Answer#1

(C) Wastes, nutrients and water

Explanation:

It is the replacement of a section or one part of an insect or a different segmented animal by a composition composed of a different section, primarily through mutation. In evolutionary developmental biology, homeosis is the transmutation of an individual organ into another, resulting from a mutation or mis expression of several developmentally important genes, especially homeotic genes.

Answer#2

(A) It dies

Unicellular organisms are the once which carries only one cell. Homeostasis is the state organism requires to operate at highest productivity. If an organism does not preserve homeostasis, the organism will not be capable to perform at full ability. Living things react to stimuli that happen inside them.

Answer#3

(A) Both unicellular and multi-cellular organisms are at risk of having too much water entering their cells if they are exposed to water containing no salts.

The amount of salt in the center of the living cells is greater and so the water will flow from the medium which has no salt to the interior of the cell where there is salt, this process is called as osmosis. And as a result to this salt content is higher in both the cellular organism.

Answer#4

(C) They are specialized in function and work cooperatively with one another.

Cells are categorized according to their function so that they can interact with one another and work together. Similarly, the once that does not possess same functions are kept apart so that living process does not pauses or stops.
