Answer:

Ferns, horsetails (often treated as ferns), and lycophytes (clubmosses, spikemosses, and quillworts) are all pteridophytes. However, they do not form a monophyletic group because ferns (and horsetails) are more closely related to seed plants than to lycophytes.

Explanation:

I'm not sure if the result is correct but I hope it helps

Answer:

Explanation:

1: Tracheophytes are characterized by the presence of vascular tissue, composed of specialized conductive cells that create "tubes" through which materials can flow throughout the plant body.

How do astronomers measure distances to stars?

a_sh-v [17]

Answer:

I found this online:

Astronomers estimate the distance of nearby objects in space by using a method called stellar parallax, or trigonometric parallax. Simply put, they measure a star's apparent movement against the background of more distant stars as Earth revolves around the sun.

A new microorganism is isolated from a lake and is placed into a solution of KCl. The voltage difference across its membrane is

Leona [35]

Answer: $\Delta U=$ 1.922x10⁻²⁰ Joules

Explanation: Electric Potential Energy (U) is the energy a charged object has due to its location in an electric field and it will only exist with the object is charged.

Voltage or Electric Potential Difference (V) is external work done to move a charge from one point to another in a electric field.

These terms have a relationship, which is given by:

$\Delta U=q\Delta V$

where

q is the charge

Proton is positive and has a charge of 1.6x10⁻¹⁹C.

Unit for potential energy is Joule (J). The relation between mV and J is

1mV = 10⁻³J

Then:

V = 120x10⁻³

V = 0.12

So, for a proton to move from the negative side of a membrane to the positive:

$\Delta U=q\Delta V$

$\Delta U=1.6.10^{-19}.0.12$

$\Delta U$ = 1.922 x 10⁻²⁰

Energy necessary to transport a proton from negative side of the membrane to the positive is 1.922 x 10⁻²⁰J.
