Answer:

passive transport

Explanation:

Diffusion is one of the ways molecules/substances move or is transported. It is the process whereby substances move from a region of higher concentration to a region of lower concentration until there is an even distribution. Movement via diffusion occurs down a concentration gradient i.e high to low.

Since diffusion occurs down a concentration gradient, which is difference in concentration of a substance, it requires no energy in form of ATP to occur. This kind of transport which requires no energy input is called PASSIVE TRANSPORT, in contrast to active transport which requires.

S_A_V [24]

Answer: Brown

Explanation:

Co- dominance occur when the two traits(dominant and the recessive) are both expressed given rise to a phenotype that is different from the parent.

Since Brown(T) is the dominant color and it is expressed over black fur(t) an organism with Tt genotype having the two alleles will be brown fur, where the black fur will not be expressed in the phenotype and the brown expressing itself over the black.

What succession is a man-made secondary succession that occurs when a farmer stops cultivating their field for a lengthy period
harkovskaia [24]

The Old field succession is a man-made secondary succession that occurs when a farmer stops cultivating their field for a lengthy period of time.

The definition of old fields, which has been a topic of discussion among modern ecologists for some time, is that they are an intermediate stage in the natural succession of an ecosystem moving towards its climax community. Many times, old field sites are marginal lands with poor soil quality that are unfit for pasture or farming.

The terms "grass and forbs stage," "shrub and sapling stage," "pole stage," and "mature forest" are frequently used by foresters to describe these stages. Forest succession is the process by which plant communities develop in a regular, predictable manner.

When a farmer gives up on a farm, the abandoned land quickly becomes overgrown with weeds and grass.

What significance do the bases AUG, or UGA have? hint use decoder chart needed. A. a. the first one is a start codon and the sec
Minchanka [31]

Answer:

The importance of the AUG and UGA bases lies in the fact that the first one is a start codon and the second one is a stop codon, respectively (option a).

Explanation:

Codons or triplets are sequences of three nitrogenous bases, in the mRNA, that determine the synthesis of a specific amino acid.

  • <em>AUG </em><em>is called the </em><em>initiation or start codon</em><em>, and is usually at the beginning of a peptide synthesis, in addition to encoding the amino acid methionine. </em>
  • <em>UGA</em><em> is a</em><em> termination or stop codon</em><em> found at the end of a petid chain when it is complete.  UAA and UAG codons are also STOP or termination codons and, together with UGA, do not code for amino acids.</em>

The biological importance of start and stop codons is to initiate the synthesis of a protein and to stop the addition of amino acids when their size is adequate.
