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 " .

Gnom [1K]

A parent with one non-functional copy of the gene is a carrier. Carriers for Cystic fibrosis will have no symptoms but they can pass the non-functioning gene on to their children.

<h3>What is cystic fibrosis?</h3>

Cystic fibrosis is a genetic disease and individual must inherit two non-functioning CF genes that is one from each parent to have CF. Both parents must have at least one copy of the defective gene and people who have only one copy of the defective CF gene are called carriers but they do not have the disease. Many couples who have a child with CF have no family history of cystic fibrosis

Cystic fibrosis affects cells that produce mucus, sweat, and digestive juices and also it causes these fluids to become thick and sticky. They block tubes, ducts, and passageways.

Symptoms include cough, repeated lung infections, inability to gain weight, and fatty stools. Treatments for this disease may ease symptoms and reduce complications.

olchik [2.2K]

Answer:

B) 0.25

Thus it will produce four different types of gametes, abc, aBC, aBc and abC will be formed. Out of 4 types of gametes only one gamete namely, aBC is with two beneficial alleles. Thus, the proportion of two or more beneficial alleles is 0.25 (1 out of 4).
