Transmitted, vertical

A transparent specimen is viewed through a microscope using transmitted light while an opaque object requires vertical illumination.

Transmitted light is the light that passes through an object. Transmitted light microscopy is any kind of microscopy in which the light is transmitted from a source located directly across the specimen from the objective. The light is commonly passed through a condenser in order to focus it on the specimen to obtain very high illumination. After the light passes through the specimen, the image of the specimen moves through the objective lens and later to the oculars where the enlarged image is viewed.

vredina [299]

Answer:

This question seem incomplete

Explanation:

This question seem incomplete. However, if the strand of the second fragment is what is provided above, then the answer is <em>51</em>

This strand/fragment is definitely a DNA strand because of the absence of uracil (U) or because of the presence of thymine (T). The four bases in a DNA are adenine (A), Thymine (T), cytosine (C) and Guanine (G). These bases also bind to one another in the pattern described below

A ⇆ T

G ⇆ C

Hence, the adenine (A) on one strand can only bind to thymine (T) on the complementary strand (and vice versa) while the guanine (G) on one strand can only bind to cytosine (C) on the complementary strand (and vice versa).

Hence, the letters seen is the question are representations of bases in a DNA strand/fragment. The number of letters/bases here are <em>51</em>

Although both br3- and i3- ions are known, the f3- ion has not been observed. explain.
Sliva [168]
Fluorine, iodine and bromine are all in the same group. Fluorine been the first element in the group has less number of electron orbitals compare with bromine and iodine. Bromine and iodine has D orbitals which can take part in their bonding activities, this allows the elements to bond in a variety of ways, but fluorine does not have the D orbital and therefore is limited in its ion formation. <span />

Do you think true water-conducting tissue is a derived character of either embryophytes or green algae? Why or why not?
ludmilkaskok [199]

Answer:

i think true water-conducting tissue is a derived character of green algae?

Explanation:

WHY?

Many characteristics of land plants also appear in algae like both are multi cellular, euks, photosynthetic autotrophs so are brown, red, and certain green algae, plants have cell walls made of cellulose and so do green algae

However, charophytes are the only present day algae that share these traits with land plants

1.Rings of cellulose-synthesizing proteins (circular rings of proteins in plasma membrane that make cellulose of cell wall)

2.Structure of flagellated sperm

3.Formation of a phragmoplast ( group of microtubules known as phragmoplast formes b/t daughter nuclei of a dividing cell, giving rise to a cell plate making cross wall that separates the daughter cells)

Comparisons of both nuclear and chloroplast genes point to charophytes as the closest living relatives of land plants

Land plants are not descended from modern charophytes, but share a common ancestor with modern charophytes

WHY NOT?

The origin of embryophytes, as these multicellular plants arose and conquered the land, was a pivotal event in the history of life on earth. Without embryophytes, there would be no animals or humans surviving on the land portion of our planet. The provide food, habitat, energy, oxygen, protection, and numerous vital other functions for the world's creatures. Human beings also benefit from the aesthetic beauty, medicines, and innumerable products derived from these diverse plants.
