Many species have embryos that look similar to one another and develop similar structures. Refer to the picture above. During th

e first stage of embryonic development for each species, what type of evolution could you conclude about the relatedness of the organisms? A) Divergent evolution because all of the species have similar structures during the first stage of development. B) Convergent evolution because a,l of the species have similar structures during the first stage of development. C) Divergent evolution because the species are fundamentally different even at the first stage of embryonic development. D) Convergent evolution because the species are fundamentally different even at the first stage of embryonic development.

Which of the following is the best description of the fluid mosaic model? A stationary triglyceride bilayer with fluid proteins.
joja [24]
Hiya once again,

The fluid mosaic model explains only but observations about the structure of functioning cell membranes. However, a lipid bilayer is used to describe the membranes of animals and plant cells. This isn't a great question to be honest with you, so let's try it like this:

Triglyceride: Ester formed by Glycerol and 3 fatty acid groups. These guys are basically made up of fats and oils. (Ex- High concentrated blood)

Phospholipid: A lipid containing a phosphate (an ester of phosphoric acid) in its molecule.

Bilayer: A film (layer) of molecules (created by lipids) that are arranged with it's hydrophobic (meaning whatever it is does NOT mix well with water... Kinda like pouring sugar into a cold glass of water and waiting for the sugar to melt) inverted at both ends of the film.

Embedded Proteins ('Intrinsic Proteins' if you wanna be fancy): Having one or more segments embedded into the phospholipid bilayer.

Stationary (phase): This is something that is mostly involved with bacterial growth

I really hope this helps! Let me know what you got and which one was right!

Which of the following pair of genotypes result in the same phenotype?
rewona [7]

Answer:

IB IB and IB i is the pair of genotypes that results in the same phenotype. genotypes means the genetic constitution of an individual organism. And phenotype is the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.

Answer: The only reaction performed by chloroplast through its chlorophyll is photosyntesis. Therefore the chemical formular is below.

   C02         +          H20           →                   C6H1206    +       O2+           H20.

(carbondioxide) +    (Water)     Chlorophyll      (glucose)  +(oxygen)+     (water)

                                                       and                                                                                            

                                                   enzymes .                    

This is the single reaction of the process of photosynthesis.However two interconnected reactions are involved light dependent stage and light independent stage.

The first reaction takes place in presence of sunlight, and it is called Photolysis of water.it is the spiting of water to H+, electrons and Oxygen. This is  the source of oxygen seen above.

             4 H20→ 4H+ + 4e- + 02.

The light independent stage; the hydrogen ion from the photolysis is transfer to the light independent stage to reduce the C02 to produce glucose.In the first equation seen above.

Since chloroplast performs photosynthesis through action of its chlorophyll, The above reaction describes the chemical formula.

B.

The cell wall  of plants is made up of the middle lamella, the primary cell wall and the secondary cell wall .

<u>Cellulose</u><u> a complex carbohydrate is the major components</u>. It contains,  monomers of  glucose in small units  linked to one another by bonds.

C

Vacuole helps in plant turgidity needed for uprightness. when filled with water provides  turgor pressure increases as the cell membrane pushes against the cell wall. The resulted turgidity  helps the plants  to maintain resistance to external pressure and therefore resist the effects of gravity.

How energy from the sun becomes thermal energy on earth
torisob [31]
Radiation is the transfer of heat energy through space by electromagnetic radiation. Most of the electromagnetic radiation that comes to earth from the sun is in the form of visible light. Light is made of waves of different frequencies.  

Hope this helps :)
