The correct answer is B. Traits or features that take effect.

Explanation

Property is a word to designate any quality that identifies identifying something or someone, distinguishing it from its peers. It can refer to different issues such as its characteristics, capabilities, possibilities, physical appearance, among others. According to the text, "There are biological properties of organisms that prevent breeding across different species". So the answer is B. Traits or features that take effect.

Darwin proposed as the process that causes evolution to occur.

Nikitich [7]

Answer:

natural selection

Explanation:

Darwin proposed natural selection as the process that causes evolution.

According to the theory of natural selection, the environment naturally selects for genes that confer fitness to organisms over every other gene. In other words, organisms that are able to adapt to an environment survive and contribute more to the subsequent generation while those that are poorly adapted contribute less and gradually fade away from the population.

For example, when a drug is taken a particular pathogen, the susceptible ones among the pathogen's population will die off while the ones with the resistance gene survive, reproduce, and pass on the resistance gene to the subsequent generation. Consequently, the same drug might not work at all for the new generations of the pathogen because the gene that confers fitness has been selected for.

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.

Phoresy is the name of the symbiotic ecological relationship where one organism attach to the other (Option B).

<h3>What is Phoresy?</h3>

Phoresy is an ecological relationship where a given biological organism travels on the body of another organism.

The life forms in this type of ecological symbiotic relationship (phoresy) are not parasitic type.

In conclusion, phoresy is the name of the form of symbiotic ecological relationship above described.
