What purpose does a fish ladder serve?
Whitepunk [10]

<u>Answer</u>: Option A

<u>Explanation</u> :

  • A<em> fish ladder</em> is also known as fish steps, fish pass or fishway.
  • It is built around waterfalls, dams and locks.
  • The purpose of building a fish ladder is to<em> facilitate the natural migration of diadromous fishes.</em>
  • A fish ladder helps the fish to pass through the barriers by leaping up or swimming through the low steps of the ladder and reach into the water on the other side.
  • Since, without the fish ladder the barriers will not allow the migration of fishes, it is essential to be built around the dams, waterfalls and locks.

What is the explanation of why avery, macleod, and mccarty's in vitro transformation experiment showed that dna, but not rna or
astraxan [27]

The Griffith's experiment, the Avery-MacLeod-McCarty experiment, and the  Hershey–Chase experiments were the set of experiments that established DNA as the key hereditary molecule. The Avery-MacLeod-McCarty experiment was an extension to the Griffith's experiment. The heat killed virulent S strain cells of the Griffith's experiment were lysed to form a supernatant containing a mix of RNA, DNA, proteins and lipids from the cell. The supernatent was equally divided into 3 parts after the removal of the lipids. The 3 parts were respectively treated with an RNAase to degrade the RNA, DNAase to degrade the DNA and proteinase to degrade the proteins. The treated supernatant was then added into the culture containing the non-virulent R cells. In case of the supernatant treated with the DNAse, no transformation of R cells into S cells occurred. The transformation of R cells to S cells occurred in the proteinase and the RNAse cases. This indicated that DNA was the hereditary molecule and not protein or RNA.

Density is mass divided by volume (d = m ÷ v). Based on the graph, what happens to a fixed mass of water when it is cooled from
Flura [38]

The mass of the water does not change. However, the volume varies with temperatures. Water at 4 degrees centigrade occupies the least amount of volume compared to other temperatures. Therefore based on the calculation of D=M/V, then water at 4 degrees centigrade has the highest density.

21. Three different processes are occurring in the drawing below. Name each process and describe it.
scoundrel [369]

The three different processes that are occurring in the above drawing are:

1. Process A: Diffusion.

2. Process B: Facilitated diffusion.

3. Process C: Active transport.

Cell transport refers to the movement of ions, molecules, or substances across the cell membrane, either into or out of the cells of a living organism.

From the above diagram, the three (3) different processes that are occurring are:

1. Process A: Diffusion.

  • Diffusion refers to the movement of gas molecules from a region of high concentration (top) to a region of lower concentration (bottom) until an equilibrium is attained or reached.

2. Process B: Facilitated diffusion.

  • Facilitated diffusion refers to the movement of substances or gas molecules across a cell membrane from a region of high concentration (top) to a region of lower concentration (bottom), especially through the help of transport protein.

3. Process C: Active transport.

  • Active transport involves the movement of substances across the cell membrane from a region of lower concentration to a region of higher concentration, against a concentration gradient and in the presence of oxygen.
