Answer:
It's d , activity level
Explanation:
Tempratement is something you are born with and it defines how an individual respond to the world
While activity level is the amount of motion that a child performs while doing some physical activity
They start in utero when the baby moves and kicks inside
When they grown up ,some children possess more energy and they don't seem to stay at one place
When they grow up they will jump and run a lot ,those who are highly active
Answer:
Analogous structures
Explanation:
These structures are similar but not derived from the common ancestor like homologous structures. Analogous structures are formed as a result of convergent evolution-type of evolution in which organisms develop on similar way but independently. An example of analogous structures are wings. Birds, insects and bats all have wings, with the same purpose (flight) but they evolved in their own way.
Answer:
the cell will eventually be replaced
Explanation:
it will be replaced since the specialization of a multi celular organism is that they live longer than the single celled organisms
Hornblende and other amphiboles have double chain silicate structures.
Tetrahedron (SiO4)^4- is the fundamental building block of all the silicate minerals. Silicate minerals comprising chains are known as inosilicates. In single chains, the ratio of silicon to oxygen is 1: 3, while it is 4: 11 in the case of double chains.
The double-chain silicates take place when tetrahedral produce a double chain by sharing two or three oxygen atoms each.
