Chromosome number of in human meiocyte is :

Which one of the given groups of structures are haploid?

Read the passage carefully and answer the questions based on the passage:
Pollen pistil interaction involves all events from the landing of pollen grains on the stigma until the pollen tube enters the embryo sac (when the pollen is compatible). When a pollen tube grows through the style and enters into the ovules, it finally discharges two male gametes in one of the synergids. Syngamy and triple fusion are two fusion events occur in angiosperms. Thus, angiosperms exhibit double fertilization. The products of these fusions are the diploid zygote and triploid primary endosperm nucleus. Zygote develops into embryo and primary endosperm cell forms the endosperm tissue. The developing embryo passes through different stages before maturation.
If there are 38 chromosomes in the zygote, how many chromosomes will be there in its haploid egg cell?

Insulin consists of two short polypeptide chains : chain A and chain B, that are linked together by disulphide bridges. The first clinical gene therapy was given in 1990 to a 4-year old girl with adenosine deaminase (ADA) deficiency. This enzyme is crucial for the immune system to function. Recombinant DNA technology, Polymerase Chain Reaction (PCR) and Enzyme Linked Immuno-sorbent Assay (ELISA) are some of the techniques that serve the purpose of early diagnosis of diseases. Transgenic animals that produce useful biological products can be created by the introduction of the portion of DNA (or genes) which codes for a particular product such as human protein (α-1-antitrypsin) used to treat emphysema. Biopiracy is the term used to refer to the use of bio-resources by multinational companies and other organisations without proper authorisation from the countries and people concerned without compensatory payment.
In 1997, an American company got patent rights on Basmati rice through the US Patent and Trademark Office. This allowed the company to sell a ‘new’ variety of bvasnmati, in the US and abroad. This ‘new’ variety of Basmati had actually been derived from Indian farmer's varieties.. Indiian Basmati was crossed with semi-dwarf varieties and claimed as an invention or a novelty. This is a case of :

If corner points of a feasible region are \((0,0),(2,0),\left(\frac{20}{19}, \frac{45}{19}\right)\) and \((0,3)\), then
(A) Maximum value of \(z=5 x+3 y\) is 10
(B) Minimum value of \(z=5 x+3 y\) is 0
(C) Maximum value of \(z=5 x+3 y\) is \(\frac{235}{19}\) and minimum value is 0
(D) Maximum value of \(z=5 x+3 y\) is 10 and minimum value is 0
Choose the correct answer from the options given below :

If \(P(A)=\frac{3}{5}, P(B)=\frac{1}{2}\) and \(P(A \cap B)=\frac{1}{4}\), then \(P(\bar{A} \mid \bar{B})\) is

Two point charges \( +4 \mu C \) and \( -2 \mu C \) are placed at a certain distance in air. They experience an attractive force \( F \). If they are brought in contact with each other and then separated to the same distance, the new repulsive force between them will be :

From a container full of orange juice, 7.5 liters was drawn out and replaced by soda water.
This process is repeated 5 more time.
The ratio of quantity of orange juice and soda water left in the container is 4:5.
How much liter of orange juice did the container originally had?
(Use \((0.44)^{1 / 6}\) = 0.802)
