Answer:

The most significant experiment performed to date on the formation of organic molecules remains that of Miller and Urey in 1952 when they sought to test the hypothesis of Oparin and Haldane that the organic building blocks of life emerged from a reducing atmosphere (Miller, 1953). Miller filled a flask with the four gaseous elements of the reductive atmosphere: methane, ammonia, hydrogen and water. He then passed electrical discharges through them to simulate lightning. After 125 h of the experiment, using the equipment available to him at the time, Miller identified several alpha amino acids contained within the residues.

juin [17]

Correct option(s):

(b) This muskmelon plant's genotype for the fruit taste gene is ff.

(c) This muskmelon plant is homozygous for the fruit taste gene.

A dominant allele is one that is capable of expressing itself even in the heterozygous condition and overshadows the effect of the recessive allele. It is usually denoted by a capital letter. Recessive allele on the contrary cannot express in presence of a dominant allele and is denoted by a small letter.

In the given case the fruit with a sour taste (phenotype) can have two possible genotypes (FF and Ff). The genotype of sweet taste is ff which is a homozygous condition.  

Note: Your question is incomplete, probably your complete question is “In a group of muskmelon plants, some individuals have sour fruit and others have sweet fruit. in this group, the gene for the fruit taste trait has two alleles. the allele F is for sour fruit, and the allele f is for sweet fruit. a certain muskmelon plant from this group has sweet fruit. this plant has two alleles for sweet fruit. Choose the correct option:

(a)  this muskmelon plant's genotype for the fruit taste trait is sweet fruit.

(b) this muskmelon plant's genotype for the fruit taste gene is ff.

(c) this muskmelon plant is homozygous for the fruit taste gene.”

sweet [91]

1. Nucleus step1: DNA is transcribed into mRNA

2. Ribosome step2: mRNA is translated into protein

3. Endoplasmic Reticulum step 3: Newly synthesised proteins are transported.

4. Golgi apparatus Step 4: Proteins are modified then transported away

In Golgi body or apparatus, the proteins are modified, sorted and packaging occurs for secretion.

How do C4 plants fix carbons?
OverLord2011 [107]

Answer:

C4 plants—including maize, sugarcane, and sorghum—avoid photorespiration by using another enzyme called PEP during the first step of carbon fixation. ... PEP fixes carbon dioxide into a four-carbon molecule, called malate, that is transported to the deeper bundle sheath cells that contain Rubisco.
