Explanation:
The eggs of a frog hatch into tadpoles, which look like little fish. After a few days, tadpoles develop legs and arms and grow into young frogs with tails. In the next few days, they grow into an adult frog with no tail. The process of growing from a tadpole to an adult frog is called metamorphosis

Well, when chromosomes cross over during prophase 1 of meiosis, the homologous pair of chromosomes exchange segments of DNA which happen to be the genes. So the significance of crossing-over during prophase 1 is that it adds genetic variation to sexually reproducing organisms.
Many physical disorders that occur in humans are attributed to the styles of living and general eating habits. Conditions such as diabetes, depression, dymentia and even some cancers are led by bad eating habits. A friend once asked me: Now that I do not want to become obesse but want to be muscular, what will I do since I have to gain mass but I don't want to overfeed? My answer was so simple. EXERCISE
Exercise can be in many forms. The most common modes of exercise are gym and athletics. If you don't do regular exercise, your body does not find a chance to get rid of the many wastes produced by different metabolic processes. Some of these products are toxic and they lead to bad effects in the body. The effect is getting lifestyle diseases.
Exercise plays a key role in boosting your memory. During and after exercise, blood becomes more oxygenated and the supply of oxygenated blood to the brain is increased. This ensures there is renewed strength in the brain parts e.g. hypothalamous and hence boosting thinking ability.
We can not overlook the fact that exercise is fun. When exercising, you are happy and happiness makes you stay healthy.
Answer:
1.
Explanation:
Xylem cell is a plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements.
2. Phloem is the vascular tissue in charge of the transport and distribution of organic nutrients. The phloem is also a pathway to signaling molecules and has a structural function in the plant body.
3. Stomata are composed of a pair of specialized epidermal cells referred to as guard cells. Stomata regulate gas exchange between the plant and environment and control water loss by changing the size of the stomatal pore.
4. Guard cells optimize leaf gas exchange in response to changing environmental conditions and their turgor is controlled by alterations in atmospheric CO2 concentration, light intensity, humidity, and the drought hormone abscisic acid.
