Na+ pumps function is to:
(a) pump na+ into the cell
(b) pump na+ out of the cell
(c) pump na+ into and out of the cell
(d) pump k+ out of the cell

Option B

Explanation:

The sodium pump is used to control the osmolarity of the cell by pumping the sodium ions out of the cells that have diffused inside the cells due to their high electrochemical gradient.

This pump plays an important role in the neurons and helps in initiating the action potentials.

This pump helps in the signals transduction from brain to various parts of the body.

Hence the correct answer is that this" Pump Na+ out of the cell".

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.
