Answer:
The Respiratory system allows entry of oxygen into the body and release Carbon Dioxide. The Oxygen travels across lung tissue into blood vessels and the blood carries the oxygen around the body. Thus the Respiratory and Circulatory system work together in gas exchange which is vital in Homeostasis
Answer:
The correct answer is <em>c.pinocytosis – liquids secreted from the cell </em>
Explanation:
<em>Pinocytosis</em> is a type of endocytosis in which substances are internalized into the cell from the celullar exterior. The components are not secreted from the cell but are uptaken into the cell. This internalization process is characterized by the formation of an invagination of the cell membrane where then is formed a vesicle surrounding the component to be uptaken.
Answer:
60-70%
Explanation:
Carbohydrate is the most important source of energy needed in preparation for prolonged exercise that consumes energy and requires endurance and strength to combat fatigue.
Carbohydrate is a more efficient fuel than fat as carbohydrates are easily broken down to supply an athlete with glucose as readily available energy, and also glycogen that is stored in the muscles, which are used as a fuel source during exercise. Hence, for prolonged heavy exercise, it is recommended that athletes need high carbohydrate consumption of 60-70 percent of their calories to maintain optimal performance.
C. Duh. No one has to agree with a successful thesis.
<u>Answer:</u>
The correct answer option is B. Green wavelengths are the least used in photosynthesis.
<u>Explanation:</u>
Plants have a pigment in them called as chlorophyll. This chlorophyll is able to absorb only certain wavelengths of the light within the light spectrum.
From that visible light spectrum, chlorophyll is only able to absorb light of red and blue wavelength. The green light is not absorbed by the by chlorophyll as it is reflected back.
Therefore, this reflection of green light makes the leaves to appear green.
