The triploid tissue in the ovule is the endosperm. Its triploid condition is attained due to the fusion of two polar nuclei and one nucleus of male gamete (also referred to as triple fusion).

Hardy-Weinberg principle is as Allele frequencies in a population are stable and is constant from generation to generation.

Companion cells, help in physiological working of sieve-tube members.

Answer: Xylem parenchyma

Correct option: c) Heads of both Front office and Accounts department

Phenotypic ratio is 3 : 1 

Genotypic ratio is 1 : 2 : 1

Humidity + salty air, dust, poor contact pressure

No, use emery paper and etc.

Silver-nickel for <100A

Silver-cadmium oxide for large currents. 

Affected by sulphur, mechanical or arcing damages (adv. Lower voltage drop)

Because corrosion rate increases. Poor surface property , large closing force required. 

Because the force developed is not steady in ac therefore contacts will chatter but if shading ring is used force developed becomes steady due to splitting of phases of flux, therefore contacts becomes bounce free and humming sound reduces. 

There are eukaryotic cells without a nucleus and others with more than one nucleus. Osteoclasts, the cells responsible for the resorption of the osseous matrix, for example, are multinucleate cells; striated muscle fibres are multinucleate too. Red blood cells are an example of enucleated specialized cells.

Cells with the delimited nucleus are called eukaryotic cells. Organisms composed of one or more eukaryotic cells are called eukaryotes.

The mains elements of the nucleus are the chromatin (made of DNA molecules), the nucleolus, the karyolymph, or nucleoplasm, and the nuclear membrane (or karyotheca).

Primary constriction is the narrower region of a condensed chromosome where the centromere, the structure that unites identical chromatids, is located. Secondary constriction is a region similar to the primary constriction, narrower than the normal the thickness of the chromosome too, and in general, it is related to genes that coordinate the formation of the nucleolus and control the ribosomic RNA (rRNA) synthesis. For this reason the secondary constrictions (that can be one or more in chromosome) is called nucleolus organizer region (NOR).

(B) Adenylve acid and Glucine floc acid

(a) Both assertion and reason are true, and the reason is the correct explanation of the assertion

(b) Both Assertion and Reason are true but Reason, is not the correct explanation of Assertion.

Chromosomal disorder:

A chromosome abnormality disorder, anomaly aberration or mutation is a missing, extra, or irregual portion of chromosomal DNA. It can be from an atypical number of chromosomes or a Structural abnormality in one or more chromosomes. Chromosome mutation was formerly used in a strict sense to mean a change in a chromosomal segment, involving more than one gone. A karyotype refers to a full set of chromosomes from an individual that can be compared to a "normal" karyotype for the species via genetic testing. A chromosome anomaly may be detected or confirmed in this manner. Chromosome anomalies usually occur when there is an error in cell division following meiosis or mitosis. There are many types of chromosome anomalies. They can be organized into two basic groups, numerical and structural anomalies.

(i) Down syndrome is a chromosomal condition that is associated with intellectual disability, a characteristic facial appearance, and weak muscle tone (hypotonia) in infancy. All affected individuals experience cognitive delays, but the intellectual disability is usually mild to moderate.

People with Down syndrome may have a variety of birth defects. About half of all afected children are born with a heart defect. Digestive abnormalities, such as a blockage of the instestine, are less common.

Individuals with Down syndrome have an increased risk of developing serveral medical conditions. These include gastroesophageal reflux, which is a backflow of acidic stomach contents into the esophagus, and celiac disease, which is an intolerance of a wheat protein called qluten. About 15 percent of people with Down syndrome have an underactive thyroid gland (hypothyroidism). The thyroid gland is a butterfly-shaped organ in lower neck that produces hormones. Individuals with Down syndrome also have an increased risk of hearing and vision problems. Additionally, a small percentage of children with Down syndrome develop cancer of blood-forming cells (leukemia).

(ii) Klinefelter syndrome is a chromosomal condition that affects male physical and cognitive development. Its signs and symptoms vary among affected individuals.

Affected individuals typically have small testes that do not produce as much testosterone as usual. Testosterone is the hormone that directs male sexual development before birth and during puberty. A shortage of testosterone can Iead to delayed or incomplete puberty, breast enlargement (gynecomastia), reduced facial and body hair, and an inability to have biological children (infertility). Some affected indivdiduals also have genital differences including undescended testes (cryptorchidism) the opening of the urethra on the underside of the penis (hypospadias), or an unusually small pensis (micropenis).

(iii) Turner syndrome is a chromosomal condition that affects development in females. The most common feature of Turner syndrome is short stature, which becomes evident by about age 5. An early loss of ovarian function (ovearian hypofunction or premature ovarian failure) is also very common. The ovaries develop normally at first, but egg cells (oocytes) usually die prematurely and most ovarian tissue degenerates before birth. Many affected girls do not undergo puberty unless they receive hormone therapy, and most are unable to conceeive (infertile). A small percentage of females with.Turner syndrome retain normal ovarian function through young adulthood.

(3)  If assertion is true but reason is false.

Answer is (1)

T ∝ r/v ∝ n²/z ∝ n/z ∝ n³/z²

T₁/T₂ = n³₁/n³₂ = 1/8

T₂ = 8T₁

= 8 × 1.6 × 10^–16 = 12.8 × 10^–16

f2 = {1}/{12.8 x 10^-16} ≈ 7.8 x 10¹⁴

Correct option is (d) n3 > n1

(c) Maximum zener current rating

(d) A nonelectrical quantity to an electrical quantity

The correct answer is: (d) 0.0001%

Correct option is C) will have discovered
