Which of the following forms of cellular transportation animal cells maintain na+/k+ level homeostasis?

a)diffusion
b)cell membrane pump
c) endocytosis
d) osmosis

The correct answer is B) cell membrane pump

Explanation:

Na+k+ ATPase pump helps animal cells to maintain Na+/K+ level homeostasis.Na+K+ATPase pump perform this function by active transport.

    The sodium potassium pump helps in the movement of both Na+ and K+ ions against their concentration gradient across the plasma membrane.

      As a result additional energy is required for the uphill transport of sodium and potassium ions in and out of the cell is derived from the hydrolysis of ATP.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.  

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;
