F Answer the following questions.​

Answer 1

Explanation:

Explanation:1) Animals move for a variety of reasons, such as to find food, a mate, a suitable microhabitat, or to escape predators. For many animals, the ability to move is essential for survival and, as a result, natural selection has shaped the locomotion methods and mechanisms used by mloving orglanisms.

2)streamlined body of fish help the fish in swimming because streamlined shape reduces the friction . It reduces friction.

3)The function is obvious fore limbsor upper limbs in human are used for grasping, holding, writing and eating and hind limbs are lower limbs are used for running walking etc. Like wise in animals limbs are used for climbing, eating, walking, running and jumping.

4)Cartilage connective tissue is important because it provides support, but is less rigid than bone. It also allows for some flexibility of movement, but has more stability than muscle. The extracellular matrix of cartilage is produced by cells called chondroblasts.

5)The most common form of X-ray used is X-ray radiography, which can be used to help detect or diagnose:

The most common form of X-ray used is X-ray radiography, which can be used to help detect or diagnose:Bone fractures.

Answer 2

Answer:

1. The major reasons for the animals to move from one place to another are given below:

• In the search of food for their survival.
• To protect themselves from their enemies.
• To get a suitable temperature for their reproduction.
• To get a perfect habitat to increase their survival rate.
• To get more prey and a safe place.
• In search of a better climate that suits their body.

    2. Fish with streamlined bodies and a stiff, crescent-shaped caudal fin or tail, tend to move rapidly through the water by swishing their tail from side to side. This action propels the fish much like sculling (rowing a boat with an oar) propels a boat. The caudal fin or tail is not the only fin a fish uses to swim.

    3. Arms and legs are connected to torso or trunk. Many animals use limbs for locomotion, such as walking, running, or climbing. Some animals can use their forelimbs (which are homologous to arms in humans) to carry and manipulate objects. Some animals can also use hind limbs for manipulation.

    4. Cartilage is an important structural component of the body. It is a firm tissue but is softer and much more flexible than bone. Cartilage is a connective tissue found in many areas of the body including: Joints between bones e.g. the elbows, knees and ankles.

    5. X−rays are types of electromagnetic radiation probably must well known for their ability to see through a person's skin and reveal images of the bones beneath it.

The most familiar use of x-rays is checking for fractures (broken bones), but x-rays are also used in other ways. For example, chest x-rays can spot pneumonia. Mammograms use x-rays to look for breast cancer.
