Given parameters:
Displacement of the seagull = 145m to the east
Time taken to cover the distance = 10s
Unknown:
Velocity = ?
Solution:
Velocity is one of the physical quantities. It is the speed in a specific direction. Hence, velocity is a vector quantity having both magnitude and direction.
So, mathematically;
Velocity =
Velocity =
= 14.5m/s due east
The velocity of the seagull is 14.5m/s due east
Answer:
e) unicellular, colonial, or multicellular.
Explanation:
Protists originates from the Kingdom Protoctista. They comprise of organisms that are unicellular (Amoeba) or unicellular-colonial (volvox) in nature and which have no tisssues, therefore they are at the cellular level of organization.
Examples include, Amoeba, Paramecium, Euglena, Slime mold, Kelp, Diatoms, DInoflagellates. etc.
Some of them are also considered to be multicellular eukaryotes e.g slime molds, red algae etc. Eukaryotic organisms are organisms that possess cells containing a nucleus.
Characteristics in which protists exhibit varies from one species to the other.
For example, the mode of nutrition in eukaryotic algae are autotrophic in nature, in amoeba, they are gifted with pseudopods(false feets) in which they used to engulf prey(a term known as phagocytosis) therefore making them to be heterotrophic in nature.
In protist, locomotion varies from one organism to another. For example, in Amoeba , locomotion is achieved by extending and retracting pseudopods, Euglena are flagellated in nature , hence they move with the flagella. In Paramecium that are ciliated in nature, they move by propelling their cilia. etc.
Transgression is to go against. Whereas marine regression is under sea floors to rise above sea levels.
Answer:
1. Greenhouse gases trap heat in the atmosphere warming the Earth’s temperature above freezing. This is known as the Greenhouse effect.
2.. The three greenhouse gases that are of most concern are Carbon Dioxide (CO2), Nitrous Oxide
(N2O), and Methane (CH4).
3.Without some greenhouse gases and the Greenhouse Effect, Earth’s temperature would be close to -18°C.
