Consider the following food chain:Plants are eaten by grasshoppers, which are eaten by mice, which are eaten by snakes.
What would happen to the other members of the food chain if the plant population was wiped out?
a. The populations of grasshoppers, mice, and snakes would increase.
b. The populations of grasshoppers and mice would increase, while the population of snakes would decrease.
c. The populations of grasshoppers would decrease, while the population of mice and snakes would increase.
d. The populations of grasshoppers, mice, and snakes would decrease.
D?

Answers

Answer 1
Answer: It's D, Without plants for the grasshopper to eat they would begin to decrease in population causing a decrease in mice population from the lack of food supply and so forth for the snake. 
Answer 2

Which reaction occurs most rapidly at standard conditions?H2(g) + I2(s) 2HI(g)

Ag+(aq) + I-(aq) AgI2(s)

Answers

 I don't know of any way to determine the relative rates of reactions other than pretty much just guessing. Even with guessing, I can't decide between the last two. Both occur in solution and (if I recall correctly) both occur quite rapidly. I would guess that the last one, just a simple precipitation, would probably be the fastest. 

(NOTE: You have the wrong equation on the last one. It should be Ag+(aq) + I-(aq) --> AgI(s) There is no subscript on the iodide ion in AgI.)

What is the opposite strand if one starnd of DNA is CAGFTTACG

Answers


From the rules of base pairing, we know that Cytosine always pairs with Guanine and Thymine always pairs with Adenine. These four bases are the only ones used as building blocks of nucleic acids DNA and RNA.

Adenine is abbreviated as A

Thymine is abbreviated as T

Cytosine is abbreviated as C 

Guanine is abbreviated as G

 There is no base abbreviated as F in nucleic acids so if we omit it, the sequence in the question should read CAGTTACG.  The complimenting  strand of the DNA molecule would therefore  read  GTAATGC

What is the biggest difference between primary succession and secondary succession ?

Answers

Answer:

In primary succession, newly exposed materials are growing and colonizing the area for the first time, while in secondary succession, it is an area that was previously occupied by organisms, but was then disturbed, then recolonized again.

Valence is the number of electrons an atom must gain or lose in order to _____ its outer energy level or have a stable octet in its outer shell.complete
lose
gain

Answers

The correct answer is complete.

Valence is the number of electrons an atom must gain or lose in order to complete its outer energy level or have a stable octet in its outer shell. In the first energy level it can have only 2, but later levels can have 8, that is, an octet.

Answer;

Complete

Valence is the number of electrons an atom must gain or lose in order to complete its outer energy level or have a stable octet in its outer shell.

Explanation;

-Valency is the number of electrons that an atom requires to gain or lose to form a complete configuration or an octet configuration.

-Atoms tend to lose or get electrons in order to achieve the electronic arrangement of atoms of the noble gases. An ion is an atom or group of atoms having an overall electrical charge. Atoms gain electrons to form cations (positively charged atom), while other lose to form anions (negatively charged atoms).

Give an example of 4 type of movable joint and describe the type of action which the joint permits.

Answers

The 4 types of movable joints are:
1) Hinge joint - a joint that works like a hinge of a door. example: elbow joint

2) gliding joint - this joint allows a bone to slide over another, this joint is found in wrists and ankles.

3) pivot joint - a freely moving joint in which movement is limited to rotation. pivot joint in the neck located at its 1st and 2nd vertebrae. allows the head to move back and forth.

4) ball and socket joint - rounded end of one bone fits the cup like end of another bone. example is the glenohumeral joint in the shoulder.

Calcium oxide (CaO) forms when an atom of calcium loses two electrons, giving it a +2 charge and an atom of oxygen picks up two electrons, giving it a –2 charge. What is calcium oxide?

Answers

calcium oxide is a basic oxide because when metals reat with oxygen they form basic oxides
