Answer:
The scaling exponent will be 0.75
Explanation:
According to a famous article by Max Kleiber*, the scaling of the metabolic rate or energy consumption for mammals Pmetab (measured in kcal/day) with the body mass Mb (measured in kilograms) is P metab = 70 Mb^0.75 .
What is the scaling exponent (the quantity x in a scaling law A = cMbx) for the specific metabolic rate as a function of the animal’s body mass?
he scaling of the metabolic rate or energy consumption for mammals P=kcal/day
Mb=body mass in kilograms
Comparing
P metab = 70 Mb^0.75 .
with A = cMb^x
the scaling exponent will be 0.75
metabolic rate is the energy(in kilojoule) consumed at rest. it accounts for the highest amount of energy a body consumes daily
Before a cell goes through cell division (mitosis), it must grow and make a copy of its DNA which is termed as an Inter-phase.
<u>Explanation:</u>
Some tasks must be carried out by the cells before they undergo division: The cell must grow, it must copy the genetic material (DNA) present in it, and divide into two daughter cells. These steps carried out by cells are termed as cell cycle.
Cells that contains a nucleus or Eukaryota cells, there are two major phases called interphase and the mitotic (M) phase. that comprises the cell cycle.
In inter-phase, growth of the cell and making a copy of its DNA is carried out.
In mitotic (M) phase, the cell separation of the DNA in the cell into two sets and division of its cytoplasm takes place resulting in the formation of two new cells.
Answer:
Forest biome: It gives us medicinal plants, woods for commercial purpose. Forests provides us rubber and fibers that is very important for the industries for making various products. They also contribute to perform ecological functions such as carbon storage, nutrient cycling, water and air purification. It also provides habitat to the wildlife.
Freshwater biome: We use fresh water for drinking water, irrigation, sanitation systems, and in industrial factories. Water used from groundwater, rivers and lakes is regained by rain and snowfall.
Marine biome: It serves huge amount of oxygen into the environment and absorbs the atmospheric carbon dioxide.
As a result of the activity of human there is a significant decrease in the number of trees. The products now used are synthetically made which were made up of natural fibers previously. The water source such as rivers, lakes, and ponds are polluted due to which many water borne diseases are increasing day by day. The accumulation of waste which are found in marine biome are reducing the number of flora present inside marine ecosystem.
Answer: Option A, C and D.
Explanation:
Cold temperature affects plants that cannot adapt to it and can eventually lead to their deaths.
If the temperature, and therefore the metabolism, remain low for an extended period, plant quality will suffer, and death may occur. A period of cold weather may also alter plant growth, as when certain vegetables “bolt,” or produce seed stalks, in response to several days at low temperatures
But maple plants in temperate region has develop some characteristics or adaptions that help its survive cold temperatures. Maple plants can tolerate frost and light freezes for short duration because they are cool plants and development characteristics to do so.
Auxins in them stimulate one final spurt before winter. Their xylems and phloems are filled with ions that prevent freezing.
They have a thick meristems which form thick scales to protect next year's buds from cold winter temperatures,
