Answer:

Refer below.

Explanation:

Pathogens:We can lessen sewage wastewater by utilizing elective techniques for treatment like drying to create pellets utilized as characteristic.

Organic Matter:We can decrease natural waste by actualizing strategies, for example, treating the soil which can support great microbes and supplement development for horticultural use.

Organic chemicals: We can diminish the utilization of hurtful pesticides and manures and use options, for example, plants to repulse creepy crawlies, for example planting marigolds and basil with vegetables, since they are characteristic repellants. We can utilize dried waste from sewage plants as a more secure manure, which assists with decreasing pathogen contamination at the same time.

Heavy metals:We can line landfills, decrease reject that goes there by utilizing just recyclable materials, and utilize elective, greener cleaning specialists at home, for example, vinegar and lemon.

Physical agents: We can all the more intensely control mechanical and power plants. They ought to be disallowed from releasing warmed wastewater from their plants. Cooling tanks could be utilized to let the temperature of the water normally lessen, and an arrangement of filtration through penetrable and non porous stone, sand, and rock could be utilized to control the stream when the water is in the long run discharged. The cooled water could be sent to be utilized underway of elective oil, similar to that got from green growth, or utilized for arranging which speaks to 1/3 of water utilization in the normal American family unit. Also, elective uses for the high temp water could be discovered, such as utilizing to warm the structure and it's pipes framework through an arrangement of radiators.

4 facts on cork cells
denis-greek [22]
<span>Cork cells are plant cells on the outer edge of the trunks/limbs of woody plants. The cell wall is made of suberin, which doesn't let gas or water through. In essence, this helps keep the water in and unwanted things (like pathogens) out. The inside of the cell is usually empty, but may have a few traces of things depending on species. These cells don't replicate and are generally considered to be dead.</span>

The following F2 phenotypic data was obtained from a Drosophila testcross using an F1 offspring. Assume red eye and brown body a
dmitriy555 [2]

Answer:

The genotype of the F1 was wy+/w+y.

Explanation:

One of the given options has a typo: the red eye-brown body offspring count should be 56 instead of 561.

<u>We have two genes with two alleles each:</u>

Red eyes (w+) is dominant over white eyes (w).

Brown body (y+) is dominant over yellow body (y).

The phenotypes of the F2 tesulting from a test cross (F1 x wy/wy) are:

  • wy+/ey (white-eye, brown body): 670
  • w+y/wy (red-eye, yellow body): 650
  • wy/wy (white-eye, yellow body): 38
  • w+y+/wy (red-eye, brown body 56

If the genes w and y are linked, two phenotypes in the F2 will be much more abundant than the other two. Recombination during meiosis is a rare event, so the most abundant phenotypes are the parentals (the ones present in the F1 parent).

Every individual in the offpsring has a <em>wy</em> chromosome, as this was the gamete inherited from the test cross individual.

In this case, the most abundant gametes are wy+ and w+y, so the genotype of the F1 was wy+/w+y.

Notice how when recombination occurs in the F1 parent, the recombinant gametes appear: wy and w+y+, which are the less abundant in the F2 progeny.
