Answer: moraine

Explanation:

A moraine is a type of landform feature which is formed by the retreating glacier. It forms a ridge like structure due to the deposition of sediments, stones, pebbles and other materials. The debris are typically sub angular to round in shape. The moraines can be found over the glacier surface as piles of sheets of debris.

On the basis of the above description, moraine is the ridge feature which has been described in the given situation.

In garden peas, one pair of alleles controls the height of the plant, and a second pair of alleles controls flower color. The al
Lerok [7]

Answer:

The parent's genotypes are:

Ddpp - tall, white parent

ddPp - dwarf, purple parent.

Explanation:

This question involves two different genes coding for height and flower color in pea plants. The alleles for tallness (D) and purple color (P) are dominant over the alleles for dwarfness (d) and white color (p) respectively.

According to this question, a tall plant with white flowers is crossed with a dwarf plant with purple flowers to produce the following proportion of offsprings: 1/4 tall purple, 1/4 tall white, 1/4 dwarf purple, and 1/4 dwarf white.

Since some of the offsprings contain recessive alleles for both or either genes, the dominant traits of the parent is controlled by an heterozygous genotype. This means that the tall plant with white flowers has a genotype: Ddpp while the dwarf plant with purple flowers has the genotype: ddPp. In a cross between Ddpp × ddPp, 1/4 of each combination of alleles is produced in the offsprings (see punnet square in the attachment).

What factor slows transcription?
Leya [2.2K]

Repressor slows down transcription.

RNA Polymerase enzyme transcribes mRNA from DNA.

Explanation:

Promoters are the 100 to 900 bps long sequence of DNA, that helps in the initiation of transcription. The transcription gets slow down as repressor bind to the promoter region hampering the attachment of RNA Polymerase enzyme which is responsible for transcription.

The process of transcription is the conversion of DNA into mRNA as told in the central dogma of molecular biology. Enzyme responsible for transcription is RNA polymerase. It is the first phase of gene expression, where DNA strand is copied into mRNA called a primary transcript.
