A Phospholipid Bilayer
The plasma membrane is composed mainly of phospholipids, which consist of fatty acids and alcohol. The phospholipids in the plasma membrane are arranged in two layers, called a phospholipid bilayer. As shown in the Figure below, each phospholipid molecule has a head and two tails

Nady [450]

Answer:

Valine-Leucine-Proline-Lysine-Histidine

Explanation:

The central dogma of biology is the process by which DNA is used to synthesize RNA and subsequently amino acid sequence (PROTEIN). The processes of transcription and translation is used in gene expression. Transcription is the process whereby the information encoded in a DNA molecule is used to synthesize a mRNA molecule. Transcription is catalyzed by RNA polymerase enzyme, which uses complementary base pairing rule i.e Adenine(A)-Thymine(T), Guanine(G)-Cytosine(C) pairing.

N.B: Thymine is replaced by Uracil in the mRNA

For the above DNA sequence: CAC GAC GGA TTC GTA, the mRNA sequence will be: GUG CUG CCU AAG CAU

Translation is the second process of gene expression which involves the synthesis of an amino acid sequence from an mRNA molecule. The mRNA is read in a group of three nucleotides called CODON. Each codon specifies an amino acid (see attached image for genetic code)

Based on the attached genetic code, an mRNA sequence: GUG CUG CCU AAG CAU will encode an amino acid sequence: Valine(Val) - Leucine (Leu) -Proline (Pro) -Lysine (Lys) - Histidine (His).

GUG specifies Valine amino acid

CUG specifies Leucine amino acid

CCU specifies Proline amino acid

AAG specifies Lysine amino acid

CAU specifies Histidine amino acid

What soil composition would be best for availability of nutrients, water, and root development? A. equal amounts of sand, clay,

Travka [436]

Soil composition would be best for availability of nutrients, water, and root development higher proportion of humus; lower amounts of clay and sand

Compared to the lower soil layers, the topsoil or surface soil often includes more organic matter and air but less clay. The topsoil typically has the highest concentration of plant roots and is more fertile than the other layers.

Nutrient management includes managing the composition of the soil. Minerals, organic material, water, and air are the fundamental elements of soil. Typically, 45% of the soil is made up of minerals. 5% organic material 20–30% water and 20–30% air are used. At best, these percentages are merely generalizations.
Numerous nutrients are found in soil, which are obtained from dead plants and animals. The plants eat these nutrients as nourishment. So soil contributes to the growth of plants by giving them sustenance in the form of nutrients.
