According to the United States Department of health and human services, in order to obtain sufficient physical activity for health, the Americans should perform the following activities:
1. 75 minutes per week of vigorous-intensity activity.
2. 150 minutes per week of moderate intensity activity.
3. Or, an equal combination of both moderate and vigorous-intensity activity
Answer:
Non-selective scatter is primarily caused by water droplets in the atmosphere. ... In the visible wavelengths light is scattered evenly, hence fog and clouds appear white. Since clouds scatter all wavelengths of light, this means that clouds block most energy from reaching the Earth's surface.
Explanation:
Answer:
If trypsin is in an acidic environment, it will decrease its function, since its optimum pH is 8.
Explanation:
Trypsin is an enzyme responsible for break peptide bonds, thus hydrolyzing proteins into peptides and amino acids. This enzyme is secreted by the pancreas and poured into the duodenum —an alkaline environment— where it acts.
<u>Since the </u><u>optimal pH for trypsin to fulfill its function is 8</u><u>, if the enzyme were placed in an </u><u>acidic environment</u><u> it would decrease its function</u>. This is because enzymes work under specific pH and temperature conditions, and changes in these conditions affect enzymatic activity.
B-Kidneys
The kidneys act as filters that strain urea and excess salts from the bloodstream to release them in the urine.
The answer is <span>B. The offspring would not cross-fertilize often with other roses.
Scent and colour of the flowers are important for pollination because they will attract pollinators. Flowers </span>with no scent and small, pale petals will attract much <span>fewer </span>pollinators than flowers <span>with scent and large coloured petals</span>. This means those bushes would not cross-fertilize often with other roses.
However, they would not die from a lack of pollinators, nor would produce seeds by asexual reproduction. Also, they would not yield more fruit than the parent rose, their fruit would probably be very small,
