Explanation:

Deoxyribonucleic acid or DNA hold all the instructions that make up an organism. It determines the physical structure and even the function of the different cells that make up all organisms.

The DNA are all stored in the NUCLEUS of cells. Typically, eukaryotic cells have a nucleus except red blood cells. The nucleus has a nuclear envelope that keeps the DNA stored inside but it has nuclear pores that allows it to interact with the cytoplasm.

In order for DNA to be replicated, it needs to be turned into messenger RNA, otherwise known as mRNA. The mRNA decodes the DNA in order for the cell to use the code. The process is called transcription.

Transcription is done within the nucleus. Before the cell can understand what to do with DNA, mRNA transcribes to know what information it needs to produce specidic proteins.

Once transcription is done, it will then bring the information out of the nucleus and into the cytoplasm. The cytoplasm is the viscous gel-like solution that holds the organelles of the cell. In the cytoplasm you have ribsomes.

Ribosomes is where protein synthesis takes place, this is why it is called the protein factory of the cell. It is a molecule that is made up of ribosomal RNA, which direct the chemical processes involved in protein synthesis. For protein synthesis to happen, it will need another type of RNA, which is the tRNA.

tRNA is transfer RNA and they translate the mRNA sequence into proteins. tRNA have amino acids attached to it.

Each 3 bases of the mRNA are collectively known as codons. These codons correspond with specific tRNA that hold the anticodons. These anticodons code for specific amino acids that they also hold.

When they pair up, the tRNA drop off the amino acid which form a chain with the other tRNA amino acids that complete the code. These chain of monomers then make the protein specific to the DNA code that was copied in the beginning.

The process of photosynthesis can be represented by the chemical formula A) C6H12O6 + 6O2 → 6CO2 + 6H2O + energy B) C6H12O6 + 6H

miv72 [106K]

C.
6CO2 + 6H2O + Light -> C6H12O6 + 6O2

Light is needed as energy in order for photosynthesis to occur. Photosynthesis converts carbon dioxide and water into oxygen and glucose.

Choose all the answers that apply.

arlik [135]

Answer:

Option A, B, and C are correct

Explanation:

Incomplete dominance means that the trait represented by two alleles expresses themselves equally thereby hindering dominance of any of the allele completely.

Now,

Let us assume the allele of red petals be represented by "R" and the allele of white petals be represented by "r"

The pink flowers will have genotype "Rr"

Now if two pink flowers are crossed, the following offsprings are produced

Rr X Rr

RR, Rr, Rr, rr

Let us evaluate all the options one by one

a) Ration of pink flower to red flower ( Rr:RR)

There are 2 pink (Rr) flower and 1 Red (RR) , thus the ration of pink flower to red flower is 2:1. Option A is correct

b) one out of four offspring is white in color, therefore the % of white flower is

$\frac{1}{4} * 100\\= 25\\$ %. Option B is correct

c) Two pairs RR and rr are homozygous, thus out of four offsprings two are homozygous. Therefore %of homozygous flowers will be

$\frac{2}{4} * 100\\= 50\\$ %. Option C is correct

d) There are two heterozygous offsprings i.e Rr, therefore the % of heterozygous is $\frac{2}{4} * 100\\= 50\\$ %. Option D is incorrect

e) half of the flowers are hybrid. Therefore option e is incorrect

Therefore, Option A, B, and C are correct
