Answer:

The answer to your question is below

Explanation:

Let's describe the phases of mitosis

Interphase is the process before cell division starts. This stage is about 90% of the cell cycle. Letter E.

Prophase: in this phase, chromatin condensates into chromosomes and the nuclear envelope vanishes. Letter B.

Metaphase: the chromosomes align in the equator. Letter F.

Anaphase. the chromosomes separate and move to the cellular poles. Letter C.

Telophase. The chromosomes are covered by a new nuclear membrane. Letter D.

Cytokinesis. is the process when the two new cells are formed. Letter A.

Why do you think the human stomach pH range is 2.0 - 3.0?

Inga [223]

Answer:

The stomach has a pH between 1.5 and 3.5 generally and this is due to the cells in the stomach releasing hydrochloric acid.

Explanation:

So as cells in the intestines gradually release more and more sodium bicarbonate, the pH raises from around 1 to around 7. Answer 2: The stomach usually has a pH of 2 or 3

What clues could you use to help determine whether movement of oslutes through the apicl and basolateral cell membranes is passi

Setler79 [48]

Answer:

Clues that can be used to determine whether the movement of solutes through the membrane is passive or active could be the molecule size, membrane potential, and the presence/absence of membrane protein.

Explanation:

Solutes transport through the cellular membrane depends on the solute size, membrane potential, and the presence/absence of integral membrane protein.

There are two types of transport: Active and passive.

- Passive transport: It does not need energy; it is driven by a chemical potential gradient. Small molecules with no charge are transported through the membrane in a gradient favor, from a high concentration region to a low concentration region. There are two types of passive transport: By simple diffusion (small molecules pass through the membrane by themselves) and by facilitated diffusion (molecules are helped by integral membrane proteins to pass through the membrane). In facilitated diffusion, the helping protein can be a channel protein (hydrophilic pores that allow the molecule to pass with no interaction) or a carrier protein (proteins with mobile parts that suffer modification as the molecule pass to the other side).

- Active transport: It does need ATP energy to pass the molecule through the membrane, as they have to move against the electrochemical gradient. This kind of transport is always mediated by a carrier protein. These proteins join with the molecules and suffer changes as they pass the solute to the other side of the membrane. An important example of this kind of transport is the sodium-potassium bomb.

What are regenerative cells ???

Afina-wow [57]

Regenerative cells are specific types of cells that can be activated in order to restore organs and tissues back to a pre-existing normal state.

Stem cells are specific cells capable of generating new specialized types of cells, thereby allowing the regeneration of damaged tissues.

For example, hematopoietic stem cells can be used to generate new red blood cells whose function is to transport oxygen in the bloodstream.

Regenerative cells can be used in tissue engineering in order to restore the function and structure of damaged organs.

In conclusion, regenerative cells are specific types of cells that can be activated in order to restore organs and tissues back to a pre-existing normal state.

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 " .
