8 4 Fig. 8.1 shows a plant shoot responding to directional light. light Fig. 8.1 (a) Name the hormone which causes the response in Fig. 8.1.
Answers
The hormone which causes the shoot to respond to directional light is auxin.
Phototropism is the process by which plants respond to light by growing toward or away from a light source. Growing toward a light source is known as positive phototropism, whereas growing away from light is known as negative phototropism.
In general, the above-ground or shoot portions of plants exhibit positive phototropism or bending toward the light. This reaction assists the plant's green portions in moving toward a source of light energy, which may subsequently be utilized for photosynthesis. On the other hand, roots will often develop away from light.
The primary photoreceptors involved in phototropism are proteins referred to as phototropin. In response to phototropin activation, auxin, a plant hormone, is carried unequally along the two sides of the coleoptile. Auxin encourages cell elongation, which makes the plant grow more on the shaded side and bend toward the light source.

The period of an ocean wave is option A. The time it takes for two successive crests to pass a stationary point.
The time period T is the time it takes one wavelength or two consecutive troughs (or crests or another wave reference factor) to bypass by using a fixed position.
A wave is a propagating dynamic disturbance of 1 or greater quantities. Waves can be periodic, in which case those quantities oscillate again and again about an equilibrium fee at a few frequencies. A wave is a disturbance in a medium that carries energy without a net motion of particles. it is able to take the shape of elastic deformation, a version of pressure, electric powered or magnetic intensity, electric ability, or temperature.

Megha fractured her leg while playing. Doctor plastered her leg and advised her to take calcium tablets and milk regularly. He also asked her to get plenty of sunlight. Why did the doctor asked Megha to take calcium tablets? Why did the doctor ask Megha to get plenty of sunlight?
Answers
The doctor informed her that because the bones in her legs tend to deteriorate and fracture, she should take calcium and vitamin D supplements to strengthen her bones.
A shattered bone occurs frequently. The bone can repair itself given enough time and the appropriate care. To keep the arm or leg fracture in place while the bone heals, a plaster cast is put. You are urged to visit a doctor the following day to ensure the plaster is fitted appropriately once it has been put.
Plaster casts typically are worn for six weeks. Depending on your age, general health, and the type of fracture, this period may be either longer or shorter. X-rays are taken throughout this time to make sure the bone is mending properly. You might be sent to an orthopedic surgeon if there are issues with the type of fracture or the manner the fracture is healing (bone doctor).
