Answer:
The metric system measures mass in grams or kilograms, distance in meters or kilometers, and volume in liters. It measures temperature in Kelvin or Celsius degrees instead of the Fahrenheit degrees used in the imperial system. The Basic Unit for Mass The metric system measures mass in grams.
Answer:
Yes.
Explanation:
Yes, a new research indicates that dogs might use a magnetic sense to navigate. Dogs has world class nose which helps them to navigate to their destination but it also has a magnetic compass that helps them in navigation. The dogs use magnetic field of the earth to find out shortcut ways in the unknown land or terrain so the hypothesis is right that dogs used magnetic sense for navigation.
Answer: The correct answer is C) Specialized.
Cells that have their own unique structures and functions are called as specialized cells. These cells are present in multicellular organisms. For performing specific function, they have unique adaptations in their structures.
For example- Nerve cells. They receive and transmit nerve impulses from one part to another part of the body. They are connected to other nerve cells or muscle cells in the body. The typical structure of nerve cell consists of body, dendrite, and exon.
As it performs the specific function, therefore, it is an example of specialized cell.
Answer:
Stabilizing Variation.
Explanation:
This is the type of variation that occurs when genetic diversity decreases as the population of organism in a particular population based on a specific trait.
Organisms with varied or specific traits within the population are selected against by the selection pressure, with little chances of reproduction, while organisms in between, ( with least variation of this particular traits) which are within the narrow range, survive to reproduce.Thus, this gives rise to narrow population of these particular organisms,(stabilizing variation) which are therefore naturally selected.
Therefore, the variation of the organisms in this population is kept close to the centre of the same mean value.
