A

Water in the soil is held tightly by adhesive forces between the water molecules and the mineral content in soil particles - in the microspores.

Explanation:

While water passes through the macrospores of soil by gravity, water passes through the microspores mainly by cohesion between the water molecules and adhesion between the water molecules and soil minerals. The more surface area for the minerals in the soil (due to finer particle sizes) the higher the water retention rate of the soil. This is why soil with more humus (like silt and clay) retains water more than soils like sand.

There is general agreement that species classified as Homo should share all of these characteristics EXCEPT
butalik [34]

Large brain size, small and flat face, small jaws and teeth, exploitation of diversity are some common features of <em>homo </em>species. <em>Different</em><em> </em><em>homo </em>species have different shapes of skulls.

Homo, genus of the family Hominidae (order Primates), is distinguished by a relatively large cranial capacity, limb structure adapted to a habitual erect posture and a bipedal gait, well-developed and fully opposable thumbs, hands capable of power and precision grips, and the ability to make standardized precision tools by combining one tool with another.

<em>Different </em><em>Homo </em>species are differentiate from skull shapes. Their body shapes also tends to vary. This is due to different environment conditions in different time zones.

However,<em> Homo</em> species show many common characteristics such as Large brain size, small and flat face, small jaws and teeth.

Describe the steps in transcription that require complementary base pairing.
nalin [4]

Answer:

Explanation:

Transcription takes place in nucleus in the presence of the enzyme RNA polymerase.

During transcription, the code present in DNA gets transcribed into the code in mRNA.  (messenger RNA)

RNA even though is a single stranded shows base pairing.

The pre-mRNA gets created from the DNA.

DNA has two strands, one of these strands acts as coding and another non coding strand.

The DNA shows base pairing with AGTC.   [A-Adenine, G- Guanine, T-Thymine and C- Cytosine]

Whereas mRNA base pairing with AGUC.  [ U- Uracil ]

Here in mRNA, instead of thymine, uracil gets paired.

According to base pairing of coding strand/sense strand of DNA, complementary bases pairs in 5'---->3' direction in mRNA.

The mRNA created looks exactly like the non-coding strand/sense strand of DNA except instead of thymine, uracil gets replaced.

The pre-RNA undergoes splicing, capping and tailing to form mature mRNA.
