Where would contour farming and terraces be most likely to be found? a. On flat, expansive grasslands b. In wetlands c. On hilly
never [62]

Farming is an agriculture practice, in which crops are harvested, cultivated, and yielded over a period of time. It can be of several types such as contour, terraces, nomadic, and sedentary farming.

<h3>What is Contour Farming?</h3>

Contour farming refers to the cultivation and growing of crops in sequential rows. The rows are level around the hill. Contour farming is found in hills and mountainous farmlands. The farming practice is common in European countries.

<h3>What is Terrace farming?</h3>

Terraces are the farming practice, in which the farmlands are formed by turning hills to form a ridged platform. Terraces are also found in the hilly regions are common in the countries China, Japan, and Southeast Asia.

Thus, contour and terraces farming is the type of agricultural practice done in the hilly and mountainous regions.

If you count 52 purple rough corn kernels and 50 yellow smooth corn kernels how many people smooth corn kernels should you expec
Vitek1552 [10]

Answer:

17

Explanation:

In corn,

Smooth kernel (S) is dominant to rough kernel (s)

Purple kernel (P) is dominant to yellow kernel (p)

Since no information has been given about the cross here let us assume it to be a standard dihybrid cross.

The phenotypic ratio of dihybrid cross is 9:3:3:1. 9/16 will show dominant phenotype for both traits, 3/16 will show dominant phenotype for one trait, other 3/16 will show dominant phenotype for the second trait, 1/16 will have recessive phenotype for both the traits.

Here,

Purple rough (P_ss) = 52

Yellow smooth (ppS_) = 50

Both of them show dominant phenotype for one trait so they each form 3/16 of the progeny.

If the total progeny was z, 3/16*z = 50

z = (50*16)/3 = 267

Total progeny = 267 kernels

Yellow rough kernels (ppss) = (1/16*267) = 17

So approximately 17 corn kernels will be yellow and rough.

The hershey chase experiment on bacteriophages showed the genetic information is carried in ____________.
Maksim231197 [3]

Answer:

The hershey chase experiment on bacteriophages showed the genetic information is carried in <u>DNA.</u>

Explanation:

In 1952 Alfred Hershey and Martha Chase provided evidence that DNA is the genetic material. These scientists carried out an experimental work with the T2 virus, a bacteriophage that infects the Escherichia coli bacteria, which reproduces by attaching itself to the outer wall of the bacteria, injecting its DNA into it where it replicates and directs, the synthesis of phage proteins. Phage DNA is encapsulated within proteins and produces phages, which lyse or break the cell and releasing phage from the progeny. They used radioactive forms (isotopes) of phosphorus and sulfur. A radioactive isotope can be used as a marker to identify the location of a specific molecule, because any molecule that contains the isotope is radioactive and therefore easy to detect. The DNA contains phosphorus, but doesn't contain sulfur, therefore phosphorus-32 was used to mark the DNA, instead the protein has sulfur, but not phosphorus, so sulfur-35 was used. Hershey and Chase found that sulfur-35 is outside the cell while phosphorus-32 was inside, indicating that DNA was the physical support of the inheritance. This work allowed the scientists to conclude that it's the DNA and not the protein that enters the bacteria during phage reproduction and that only the DNA is transmitted to the phage of the progeny.
