Some organisms can create a sodium motive force by pumping sodium ions across a membrane using the energy of an electron transpo

rt system. In order for this sodium motive force to provide useful energy for the cell, the organism must contain __________.

Answer:

an Na+ driven synthase

Explanation:

Some organism have sodium driven synthase which actively transport the sodium ions across the cell membrane with the help of energy of electron transport chain.

In most bacteria, there are antiporters that are used to exchange sodium ions with proton which is driven by electrochemical proton potential. So these organisms converts proton motive force into sodium motive force.

In humans also there are antiporter called sodium-potassium pumps which use ATP energy to transport sodium out of the cell.

A dihybrid cross is performed between plants that differ in two Mendelian traits: Stem length (T or t) and flower coloration (R
Dahasolnce [82]

Answer:

A. 3/16

Explanation:

The four possible outcomes for Stem length are:

Tt, tT, TT and tt.

The dominant trait (tall stems) will manifest itself in 3 out of 4 outcomes, so its ratio is 3/4.

The four possible outcomes for flower coloration are:

Rr, rR, RR and rr.

The non-dominant trait (white flowers) will manifest itself in 1 out of 4 outcomes, so its ratio is 1/4.

Multiplying both ratios gives us the ratio of offspring that have tall stems and white flowers:

\frac{3}{4}*\frac{1}{4}=\frac{3}{16}

Therefore, the answer is A. 3/16

All parts of nonvascular plants must be near water because they have: B. tiny roots.

<h3>What is photosynthesis?</h3>

Photosynthesis can be defined as a biological and chemical process through which living organisms such as green plants (autotrophs), transform light energy (sunlight) into stored chemical energy.

<h3>What is a nonvascular plant?</h3>

A nonvascular plant can be defined as a species of low-growing, non-flowering plant that lacks specialized conducting channels, deep roots or vascular tissues (xylem and phloem) for the transportation of nutrients and absorption of water.

Generally, nonvascular plants usually possess tiny roots and the the dominant stage of their life cycle is the photosynthetic gametophyte. Some examples of a nonvascular plant include the following:

  • Moss
  • Liverwort
  • Bryophyte

In conclusion, we can infer and logically deduce that all parts of nonvascular plants must be near water because they have tiny roots.
