Flower is not found in all plants, but in higher level of flowering plant, flower is important part of plant because it has ….

Function as plant ornament
Sepal to protect inner parts of the flower
Stamen and pistil as generative reproduction organs
Interested colours

Correct Answer

A. Stamen and pistil as generative reproduction organs

Explanation

In higher level of flowering plants, the flower is an important part of the plant because it contains the stamen and pistil, which are the generative reproduction organs. The stamen produces pollen, which contains the male reproductive cells, while the pistil contains the female reproductive cells and receives pollen for fertilization. These organs are crucial for the plant's reproductive process and the production of seeds, ensuring the continuation of the species.

If backbone bends to the side ( to the left or to the right ), the back bone disorder is named …

Rachitis
Lordosis
Kyphosi
Scoliosis

Correct Answer

A. Scoliosis

Explanation

Scoliosis is the correct answer because it is a back disorder characterized by a sideways curvature of the spine. When the backbone bends to the side, either to the left or to the right, it is a clear indication of scoliosis. This condition can cause the spine to appear curved, leading to an abnormal posture and potential complications if left untreated.

Perfect flower is flower that has ….

Pistil and flower stalk
Flower stalk and petal
Stamen and pistil
Petal and stamen

Correct Answer

A. Stamen and pistil

Explanation

A perfect flower is a flower that contains both male and female reproductive organs, namely the stamen and pistil. The stamen is the male reproductive organ that produces pollen, while the pistil is the female reproductive organ that contains the ovary, style, and stigma. The presence of both stamen and pistil allows for self-pollination or cross-pollination, ensuring successful reproduction in the flower.

Liquid that has function as lubricator ilquid that is found in joint cavity is ….

Serum
Phlasm
Synovial liquid
Lymph liquid

Correct Answer

A. Synovial liquid

Explanation

Synovial fluid is the correct answer because it is a lubricating liquid found in the joint cavity. It helps to reduce friction between the bones during movement and also provides nutrients to the cartilage. This fluid is produced by the synovial membrane and plays a crucial role in maintaining the health and functionality of the joints.

The track which is shown in the cross section of root is ….

Lenticel
Water track
Casparian strip
Diffusion gap

Correct Answer

A. Water track

Explanation

The correct answer is "water track." In plant roots, water tracks are specialized structures that allow for the movement of water and nutrients from the soil into the plant. These tracks are typically found in the cortex of the root and consist of interconnected cells that create a pathway for water flow. The presence of a water track in the cross section of a root indicates the plant's ability to efficiently transport water and nutrients.

Q and S
P,Q and R
Q, R and S

Correct Answer

A. Q and S

Explanation

The pistil is the female reproductive organ of a flower, consisting of the stigma, style, and ovary. In the given figure, Q and S are labeled as the pistil. Therefore, the correct answer is Q and S.

Below are factors that couse water and mineral can move upward from root to leaves, except ….

Osmosis
Root pressure
Absorptive capacity of leaf
Capillarity power

Correct Answer

A. Osmosis

Explanation

Osmosis is not a factor that causes water and minerals to move upward from the root to leaves. Osmosis is the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. In the context of plant physiology, osmosis is involved in the movement of water into the roots from the soil, but it does not directly contribute to the upward movement of water and minerals through the xylem vessels. Instead, the upward movement is primarily driven by root pressure, absorptive capacity of the leaf, and capillarity power.

Interbones connection that each other cannot be moved ….

Synarthrosis
Amphiarthrosis
Diarthrosis
Kyphosis

Correct Answer

A. Synarthrosis

Explanation

Synarthrosis is the correct answer because it refers to a type of joint in which the bones are tightly connected and cannot move. This type of joint provides stability and strength to the skeletal system. Examples of synarthrosis joints include the sutures in the skull and the joint between the teeth and the jawbone.

The properties of smooth muscle is ….

Works under unvoluntery, it has many cell nucleus
Works beyond unvoluntery, it has one cell nucleus
Works under unvoluntery, it has one cell nucleus
Works beyond unvoluntery, it has many cell nucleus

Correct Answer

A. Works beyond unvoluntery, it has one cell nucleus

Explanation

Smooth muscle is a type of muscle tissue that is responsible for involuntary movements in the body, such as the contraction of organs like the stomach and blood vessels. Unlike skeletal muscle, which is under voluntary control, smooth muscle works beyond voluntary control. Additionally, smooth muscle cells typically have one nucleus per cell, distinguishing them from skeletal muscle cells, which have multiple nuclei. Therefore, the correct answer is "Works beyond unvoluntery, it has one cell nucleus."

Cardiac muscle is included into perticular muscle, because ….

Its cells heve roll shape, smooth work
The cells of skeletal, works consciously
Has skeletal shape, smooth work
Its cells heve roll shape, works consciously

Correct Answer

A. The cells of skeletal, works consciously

Explanation

The correct answer is "The cells of skeletal, works consciously." This is because cardiac muscle is a type of muscle tissue that is found only in the heart. Unlike smooth muscle, which is found in the walls of organs and blood vessels, and works involuntarily, cardiac muscle is similar to skeletal muscle in that it is striated and contracts consciously. This means that it can be consciously controlled, allowing us to control our heart rate and the strength of our heart contractions to some extent.

1 and 4
2 and 3
3 and 2

Correct Answer

A. 3 and 2

Explanation

The correct answer is 3 and 2. In the given figure, the numbers 3 and 2 represent the xylem and phloem vascular tissues respectively. Xylem is responsible for transporting water and minerals from the roots to the rest of the plant, while phloem is responsible for transporting sugars and other organic molecules from the leaves to the rest of the plant. Therefore, the correct answer is 3 and 2.
