in 2002, the fossil of a four- winged dinosaur was discovered in china and named a microraptor. what was the significance of the discovery

Answers

Answer 1

Answer: The answer is: the discovery resulted in some theories about the origin of flight.

Microraptor was a four-winged dinosaur, that lived about 120 million years ago. It is suggested that it was able to fly using all for limbs. It also had feathers, which suppose the connection between birds and dinosaurs. But, its feathers are used for gliding and not for flying. This suggests that flight evolved in the trees and not on the land.

Which of the following represents a gene pool?A. all alleles of one trait

B. all genes of a single individual

c. all genes of all the individuals in a specific population

Answers

The Gene pool represents all the genes of all the individuals in a specific population. So, the correct option is C.

What do you mean by the Gene pool?

It is defined as the total genetic diversity found within a population of a species.

Gene pool is the sum total of all the genes and possible combinations of genes that occur in any given population.

Therefore, the Gene pool represents all the genes of all the individuals in a specific population.

if a geologist finds a rock while in the field chances are high tjat the rock contains. A iron. B carbon. C potassium. and D silicon.

Answers

The correct answer is option D, Silicon

Rocks are basically made up of elements which are abundant in the Earth’s crust. Since Earth’s crust has rich reserves of silicon and oxygen, it is made up of silicate minerals. The silicate minerals are basically of two types – light (70 % Silica content) and dark (50 % silica content) silicates. Light silicates are knows as quartz, muscovite and feldspar and Dark silicates includes ferromagnesian (consisting of iron and magnesium).

What is the acceleration of an object if it goes from a velocity of +25 m/s to rest in 5.0 s?A. –5 m/s^2

B. +5 m/s^2

C. –25 m/s^2

D. +25 m/s^2

Answers

In this question, there are several information's that can be used to determine the right answer.Let us first check all the information's that have been provided in the question.
Initial velocity = 25 m/s
Final velocity = 0 m/s
Initial time = 0 second
Final time = 5 second
Now we can write an equation to determine the acceleration.
Acceleration of the object = (Final velocity - Initial velocity)/ (Final time - Initial time)
   = (0 - 25)/ (5 - 0)
   = - 25/5
   = -5 m/s^2
So we find the acceleration of the object as -5m/s^2. the correct option among the given options in the question is option "A".

the correct answer is -5 m/s^2

hope this helps:)
