Answer:
The correct answer will be option- C.
Explanation:
The endo-symbiotic theory was given by Lynn Margilus in 1967 which explained the origin of complex eukaryote from simple prokaryotes.
The endosymbiotic theory stated that a eukaryote became complex after the ingestion of prokaryotic cells which became permanent which proved useful to each other.
The presence of mitochondria is evidence supporting the endosymbiosis which is thought to have evolved from a prokaryotic chemosynthetic bacteria in past.
Thus, option- C is the correct answer.
14.75mph
Explanation:
Given parameters:
Distance traveled = 177miles
Time of arrival in Dallas = 12hours
Unknown:
Average speed = ?
Solution:
The average speed is the total distance covered divided by time taken for the entire travel.
It is the rate of change of distance with time.
Average speed = 
since total distance traveled = 177miles, time of arrival = 12hrs
Average speed = 
= 14.75mph

Answer:
Option D = 3.4 g/mL
Explanation:
Given data:
Volume of water = 21.2 mL
Volume of water + object = 27.8 mL
Mass of object = 22.4 g
Density of object = ?
Solution:
First of all we will calculate the volume of object.
Volume of object = Volume of water+ object - volume of water
Volume of object = 27.8 mL - 21.2 mL
Volume of object = 6.6 mL
Density of object:
d = m/v
d = 22.4 g/ 6.6 mL
d = 3.4 g/mL
Answer:
Explain how heat in the atmosphere and water affect weather?
Amount of water in the atmosphere determines the amount of rainfall which depicts how cool the environment would look like.
Water has a great effect on the weather as evaporation helps to determine whether there would be heat or not, when there is high rise of evaporation it shows that the environment or weather is hot vice versa
