Biology Test 139

The anterior part of the genital part contains the female gonopore, spermathecal pores and collateral glands. In males, the genital pouch lies at the hind end of abdomen. It is bound dorsally by the 9th and 10th terga and ventrally by the 9th sternum.
Hence, the correct option is (A).

Cardiac muscle tissue is a specialized, organized type of tissue that only exists in the heart. It is responsible for keeping the heart pumping and blood circulating around the body. Cardiac muscle tissue, or myocardium, contains cells that expand and contract in response to electrical impulses from the nervous system.

Hence, the correct option is (C).

In the given sequence AUG is the start codon which will initiate the process of translation so it will continue from AUG to CUG because UGA is a stop codon that does not code for any amino acid, other stop codons are UAG & UAA.

Hence, the correct option is (C).

The order Polymoniales consists of Felidae Convolvulaceae and Solanaceae like families, Solanum and Petunia like genera, lupus-like species.

Canidae is a family of mammals in the order Carnivora, which includes domestic dogs, wolves, coyotes, foxes, jackals, dingoes, and many other extant and extinct dog-like mammals.

Hence, the correct option is (B).

Mitosis is understood to involve five phases, based on the physical state of the chromosomes and spindle. These phases are prophase, prometaphase, metaphase, anaphase, and telophase.

Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses.

Hence, the correct option is (D).

The leaves of Mimosa have the capability to display thigmonasty (touch-induced movement). In the sensitive plant, the leaves respond to being touched, shaken, heated, or rapidly cooled. The response can be seen moving down the midvein where it triggers the movement of each individual leaflet.

Hence, the correct option is (B).

The true fruit can be defined as the fruit, which is formed from the fertilized ovary of the flower. Watermelon, lemon, cherry, blueberries are all examples of true fruits.

The false fruits can be defined as the fruit, which is formed from the ripened ovary along with some other parts of flower-like the base or receptacle, the perianth etc. Apple, banana, cashews, strawberry, are all examples of false fruits.

Hence, the correct option is (B).

Plants growing in soils that have acidic nature, a rich amount of humus and a lack of ions are known as oxalophytes or oxyphytes.

Oxalophytes are the plants that grow in acidic soil maintained at pH 5.5 as this enables the plant to absorb nutrients required for growth.

Hence, the correct option is (C).

The respiratory system can be separated into a conducting and a respiratory portion. The conducting portion consists of the air-transmitting passages of the nose, nasopharynx, larynx, trachea, bronchi and bronchioles. This part of the respiratory system serves to filter, warm and humidify air on its way to the lungs.

Hence, the correct option is (B).

The fossa ovalis is a depression in the right atrium of the heart, at the level of the interatrial septum, the wall between the right and left atrium. The fossa ovalis is the remnant of a thin fibrous sheet that covered the foramen ovale during fetal development. It is a vestige of the foramen ovale, and its floor corresponds to the septum premium of the fetal heart.

Hence, the correct option is (B).
