How does contour plowing in farming help to prevent pollution?

Biology
1 answer:

8 0

D) Contour plowing is used to reduce erosion and sediment pollution.

Explanation:

Contour plowing in farming helps to prevent pollution by reducing surface erosion of topsoil and preventing sediment pollution.

Contour plowing is a farming technique in which crops are planted along the slopes of hills or contoured areas.

  • The rate at which rain water and precipitation moves along slope terrain is very fast.
  • This causes the washing off of the the topsoil on hills to eroded very fast.
  • Contour plowing breaks the slope and farming is done along movement on the contour.
  • This prevents topsoil erosion.
  • It also prevents sediment pollution in nearby streams and water bodies that are located around the valley at the base of the hill.

Which wold tell you for sure if you had a sample of real gold​
Advocard [28]

To perform this test to check if gold is real, make a light, tiny scratch on the item using a small nail file. Choose a spot that is not noticeable if possible. Use a dropper to apply a small drop of nitric acid to the scratch. If there is no reaction, then the piece is probably made from real gold.

In a diploid species of plant, the genes for plant height and fruit shape are syntenic and separated by 18 m.u. Allele D produce
FinnZ [79.3K]

Answer:

C)Parental: 41% Dr, 41% dR; recombinant: 9% DR, 9% dr.

Explanation:

The notation Dr/dR for genotypes means that one homologous chromosome has the alleles Dr and the other homologous chromosome has the alleles dR.

The heterozygous plant  Dr/dR will produce 4 types of gametes: two identical to the chromosmes the individual has in its somatic cells (called parental), and two gametes which will be a mix of the alleles in the homologous chromosomes (called recombinant).

  • Dr: parental
  • dR: parental
  • DR: recombinant
  • dr: recombinant

To calculate the frequency of each type of gamete, we must use the formula:

Distance (map units) / 100 = frequency of recombination.

18 mu / 100 = 0.18.

The total frequency of recombination between the genes D and R is 0.18, but every time crossing over happens, two recombinant gametes are generated. Therefore, each recombinant gamete will have a frequency of 0.18/2=0.09 = 9%.

The frequency of parental gametes will be:

1 - frequency of recombinant gametes

1 - 0.18 = 0.82

But there are 2 parental gametes, so each of them will have a frequency of 0.82/2=0.41 = 41%.
