The given question is incorrect. The correct question is:
Which of the following is true about a plant with the genotype AABbcc?
a. It is heterozygous at two loci.
b. It is homozygous at two loci.
c. It is triploid.
d. It will not express the recessive c allele.
e. It has recessive alleles at three loci.
Answer:
b. It is homozygous at two loci.
Explanation:
When an organism has two identical alleles of a particular gene, it is said to be homozygous for that gene. The given genotype "AABbcc" has a dominant allele for "A" and the recessive allele for "c". It is homozygous for these two genes but is heterozygous with respect to "B". The presence of three complete sets of chromosomes makes the organisms triploid. The given genotype carries two alleles for each gene and therefore, it is diploid.
Archaebacteria are obligate anaerobes, i.e., they flourish in the strict absence of oxygen., and that is why only they can undergo methanogenesis.
The cell membranes of the Archaebacteria are composed of lipids.
The rigid cell wall provides shape and support to the Archaebacteria.
Replacing native gel electrophoresis with SDS results in eluates with no enzymatic activity because it confers a negative charge to proteins, thereby neutralizing them.
<h3>What is sodium dodecyl sulfate?</h3>
The sodium dodecyl sulfate (SDS) is a detergent used in molecular biology laboratories.
This detergent (SDS) confers a negative charge to proteins, thereby neutralizing them (loss of their enzymatic activity).
In conclusion, SDS results in eluates with no enzymatic activity because this detergent may neutralize them.

Answer:
Transgenic organism:
Transgenic organism may be defined as the organisms whose genetic makeup has been modified by the molecular techniques. These transgenic organism are mainly produced in the laboratory for research work. The genes of one species can be modified or some other gene has been inserted in the organism.
Advantage of transgenic crop.
The transgenic crop has been produced by the genetic alteration of the crop. The main advantage of the transgenic crop is to develop the enhanced quality and quantity of crop. Vitamin rich golden rice has been produced by the transgenic crop.
Answer:
Endoplasmic reticulum
Explanation:
Endoplasmic reticulum is known to be a site where many cellular components are synthesized and also, it is found to be internal membrane of the eukaryotes. Thus, endoplasmic reticulum exists in two forms which include rough and smooth endoplasmic reticulum. Furthermore, it perform important role in the synthesis of lipids and modification of proteins.
