Answer:

C. A perfect, mutation-free society

Explanation:

Mutation is a genetic phenomenon involving the alteration or change in the genetic sequence of a gene. Mutation is commonly caused by mutagens (chemical substances that induce mutation), DNA replication mistakes or errors etc.

According to this question, if DNA replication occurs without error, this means that mutation will likely not occur, leading to a perfect, mutation-free society.

Which of these gymnosperms are known to be important in maintaining the balance of carbon in an ecosystem?

CaHeK987 [17]

The correct answer is: [D]:

___________________________________________________

→ " redwood tree forests " .

___________________________________________________

Note: Let us consider the other answer choices.

___________________________________________________

Choice: [A]: "garden flowering plants" ; is incorrect — since these are not generally considered to be part of a true or traditional "ecosystem" ; and especially since "garden flowering plants" are, in fact, "flowering plants" — which means that they are "angiosperms" — Not "gymnosperms ".

→ Rule out: " Choice: [A] " .

__________________________________________________

Choice: [B]: " ferns and liverworts " ; is incorrect — since both ferns — as well as liverworts — are Not "gymnosperms ".

Liverworts are "bryophytes" {which lack true vascular tissue] ; and ferns are "pterophytes" ["seedless vascular plants"].

→ Rule out: " Choice: [B] " .

___________________________________________________

Choice: [C]: " mosses and horsetails "; is incorrect ; since both mosses — as well as horsetails — are Not "gymnosperms ". Mosses are "bryophytes" (see aforementioned) ; and horsetails are "non-seed bearing plants" that spread vegetatively [underground; by asexual reproduction — and Not by seed .].

→ Rule out: " Choice: [C] " .

__________________________________________________

Choice: [D]: " redwood tree forests " ;

— is the only answer choice provided that is a "gymnosperm".

Furthermore, the "redwood tree" is a conifer (i.e. "coniferous; or, "cone-bearing" plant} that reproduces through seeds spread by "cone") — and all "conifers" are a type of "gymnosperm."

Furthermore, "redwood trees" grow large and tall, and redwood forest communities within an ecosystem; due to there size and presence, are: "known to be important in maintaining the balance of carbon in an ecosystem."

__________________________________________________

→ As such, the correct answer is:

__________________________________________________

→ Answer choice: [D]: " redwood tree forests " .

The primary difference between what qualifies as serial murders and what qualifies as mass murders is the selection of victims.

maxonik [38]

I believe the appropriate answer is a cooling-off period. The cooling off period us described as the state of returning to the offender's usual way of life between homicides. The key distinction between the serial killers and mass or spree killers is this emotional cooling off period in which the killer blends back into his/her normal life.
