Answer:
Explanation:
Haemoglobin in the red blood cells which is one of the components of the circulatory medium, the blood, has a great affinity for oxygen hence transports it around the body during circulation. It is the circulatory system that carries both oxygenated and deoxygenated blood around the body, between the lungs and the heart. The circulatory system takes blood with carbon dioxide to the lungs where oxygen that entered into the body through the nostrils will be exchanged with carbon dioxide in the alveoli. Consequently carbon dioxide will go out of the body through the nostrils via the trachea and haemoglobin in the red blood cells in the blood( blood capillaries) will
carry oxygen which is transported around the body.
Cooling a substance causes molecules to slow down and get slightly closer together, occupying a smaller volume that results in an increase in density
<u>Answer</u>:
Science is not limited to the laboratory because it has done in a laboratory to study the physical, chemical and biological aspects of the natural system. It mean that science presents everywhere and happening at all times. It also mean that anyone can become a scientist and they can conduct the experiments with the data and a hypothesis.
<u>Explanation</u>:
Science is the study of the physical, chemical, biological, and mathematical study of nature. The science is studied in laboratory conditions to validate the various reaction and principles occurring in natural systems.
In a laboratory, small system or model is made to study the particular aspect of a large system. Thereby, science in the laboratory helps to find out the science of the actual world. Various principles, machines and designs are inspired by the natural systems.
The roots of eh gymnosperms are long and deep, with the advantage to gather deep water. Thus, option D is correct.
Roots are the important network of tissues that gathers the water and essential nutrients from the soil and allow growth.
<h3>What type of roots are in Gymnosperms?</h3>
The gymnosperms are advanced plants with bare seeds. The roots system in the gymnosperms is the taproot system.
The root system in the gymnosperm is the long deep roots that are immersed deep inside the soil.
Thus, the advantage of roots to gymnosperms arises from the deep root for gathering water below the surface. Thus, option D is correct.
