Biology

Answer:

 Fruit (pods or hulls etc) bearing seeds are a means of dispersal for plants because they are sessile and have no means to move once germination anchors them with roots. Seeds are the dormant propagules or the quiescent, dispersing agents of the next generation that travel away from the parent plant  in a disposal. This is why fruit/seeds are categorized by their dispersal by wind (hydrochoric) or by animals (zoochoric).

Paladinen [302]

Answer:

The question is incomplete, it lacks the mRNA sequence. The sequence is as follows:

5′−AUGGCAAGAAAA−3′

The answer is Met-Ala-Arg-Lys

Explanation:

Gene expression in living organisms involves the process of transcription and translation. Transcription is the synthesis of a complementary strand of mRNA from a DNA template while translation involves using the transcibed mRNA as a template to synthesize amino acid sequence (proteins).

In the RIBOSOME, where the synthesis of protein occurs, the mRNA nuceleotide sequence is read in a group of three nucleotides called CODON. Each codon specifies a particular amino acid. The collection of all codons is the genetic code. Hence, for a specific mRNA sequence that reads 5′−AUGGCAAGAAAA−3′. The nucleotides will be read three at a time starting with AUG which is a codon that encodes METHIONINE.

Next, GCA is a codon that encodes ALANINE

Next, AGA is a codon that encodes ARGININE

Finally, AAA is a codon that encodes LYSINE.

Hence, the amino acid sequence using the above mRNA sequence, will read: Met-Ala-Arg-Lys

The uppermost horizon, horizon O, in this profile is composed mostly of _________, while the lower horizon, horizon C, is compos
pickupchik [31]

<u>Answer;</u>

C) organic matter; rocks.

The uppermost horizon, horizon O, in this profile is composed mostly of <u>organic matter</u>, while the lower horizon, horizon C, is composed mostly of <u>rocks.</u>

<u>Explanation;</u>

-Soil contains the following major horizons, that is A B and C. Some soils may have horizon O, which may be thin or thick or even lack in some soils. This O horizon is found at the surface of many soils and normally contains organic materials at various decomposition stages. these are materials such as plants, leaves and bugs.

-C horizon is the layer that is below the B horizon. It contains larger weathered fragments or broken up-bedrock.
