Answer:
They concluded that these antibodies were a) Globular proteins
Explanation:
Globular proteins are known to be water-soluble, spherical in shape and to be polypeptides as well. Compared to the other options provided, the selected one is the most correct.
<span>Water covers around 70% of the Earth's surface and its high specific heat plays a very important role as it is able to absorb a lot of heat without a significant rise in the temperature. When temperatures decrease, the heat which is stored is released, restraining a rapid drop in temperature. The combined effect of these processes is a buffering of temperature on the Earth.</span>
The right answer is: Leptin
.
Leptin is a hormone closely linked to the regulation of energy consumption and expenditure: appetite, metabolism, and hunger.
A hormone is a protein with a messenger function. This means that once released into the bloodstream, she goes to another part of the body to transmit a message to specific receptors.
Leptin is manufactured in white adipocytes (adipose tissue) where triglycerides (fats) are stored and acts on the hypothalamus.
Answer:
The correct answer is option D. "1,200 years".
Explanation:
The giant sequoia (<em>Sequoiadendron giganteum</em>) are the most massive trees in the world, and the tallest is one sequoia called "General Sherman" with a height of 83.8 m. "General Sherman" is estimated to be 2,000 years old, and is estimated that a sequoia tree can live up to 3,500 years. Therefore, an 80-meter sequoia tree in the forest most likely will have more than 1,000 years.
A. into a climax community; species replaces another
B. and replaces another; ecosystem becomes stable
C. on unoccupied ground; biological community replaces another
D. and then fails; niche changes
E. intraspecific competition; experiences interspecific competition
Answer:
C. on unoccupied ground; biological community replaces another
Explanation:
Primary succession is a gradual change that occurs on bare rocks or areas that have no life existing on it before. It could take several years to be colonized by living things.
On the other hand, secondary succession are changes that occur when one biological community replaces another as a result of factors such as wild fires, or take place in abandoned farm land. New species of organisms take over the area that has life existing on it already. Secondary succession occurs on areas or land that has been colonized initially before.
