Darwin hypothesized that artificial selection and natural selection functioned the same way, wherein traits that were desirable gave the individuals an advantage: Those who could survive would live long enough to pass the desirable traits on to their offspring.

What di eukaryotes most likely evolve from?

otez555 [7]

Answer:

Prokaryotes.

Explanation:

Most of the Eukaryotes most likely to evolve from the Prokaryotes. Prokaryotes are basically unicellular organisms that lack internal membrane-bound structures. So, they do not carry nucleus and generally have a single chromosome. Most of them have a cell wall outside the plasma membrane, which is a thin layer of lipid that completely surrounds the cell. Prokaryotes reproduce by binary fission method.

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 " .

Describe the movement in the amoeba

Oliga [24]

Amoebae move by growing an extension of their bodies in the direction of movement and then flowing into it. This extension is called a pseudopod because when it's fully extended it resembles a limb, despite being only an extension of the amoeba's plasma membrane.
