4 0

Mature elodea leaves has the average of 35 chloroplasts in each cell while young elodea leaf has the average of 25 chloroplasts in each cell.

Elodea cell is a plant cell that has many organelles such as a nucleus, many chloroplasts, a hard cell wall, a thin and transparent cell membrane, cytoplasm, and a central vacuole. The number of chloroplasts present in each elodea cell is determined by some factors such as the age of the leaves and the presence of any plant growth stimulants. Mature elodea leaves have the tendency to have more chloroplasts than young elodea leaves. Mature elodea leaves has the average of 35 chloroplasts in each cell while young elodea leaf has the average of 25 chloroplasts in each cell.

The rate at which respiration is occurring in a mammal can be indicated by the rate of
Vitek1552 [10]

Answer:

All life respires, or breathes. Respiration in mammals is similar to respiration in other air-breathing animals. Respiration extracts oxygen from the air, which is then used by cells. Respiration also carries waste carbon dioxide away from the cells. Although respiration depends on other systems, like the circulatory system, to take oxygen and carbon dioxide to and from cells, the respiratory system has the primary responsibility of bringing oxygen in to a mammal's body and sending carbon dioxide into the atmosphere.

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 " .

___________________________________________________

 <u>Note</u>:  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" —  <em><u>Not</u></em>  "<em><u>gymnosperms</u></em><em> </em>".

      →  Rule out:  " Choice:  [A] " .

__________________________________________________

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

          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 <em><u>both</u></em> mosses — as well as horsetails — <u><em>are Not  </em></u><u>"</u><u><em>gymnosperms </em></u>".   Mosses are "bryophytes" (see aforementioned) ; and horsetails are "non-seed bearing plants" that spread vegetatively [underground; by asexual reproduction — <em><u>and Not by seed</u></em><em> .</em>].

      →  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:  "<em><u>known to be important in maintaining the balance of carbon in an ecosystem</u></em>."

__________________________________________________

 →  As such, the correct answer is:

__________________________________________________

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

__________________________________________________

Hope this helps!

    Best wishes to you in your academic endeavors

           — and within the "Brainly" community!
