Reproductive cells are created by _____. mitosis meiosis cytokinesis

Answers

Answer 1

Answer: The correct answer is meiosis. Meiosis is a process where a cell divides into two where these cells contain half of the genetic information from the original cell. Meiosis produces daughter cells containing 50% information from the mother and 50% from the father.

Answer 2

Answer:

The correct answer is meiosis.

Which best describes the oxidizing agent in this reaction? Cl2(aq) + 2Brmc003-1.jpg(aq) mc003-2.jpg 2Clmc003-3.jpg(aq) + Br2(aq)

Answers

The balanced chemical equation is this:
Cl2(aq) + 2Br-(aq) --> 2Cl- + Br2(aq)

Looking at each substance involved in the reaction:
Cl2 has 0 charge and gains a charge of -1 after the reaction
Br- has a charge of -1 but turns to 0 after the reaction

Cl2 gained an electron which means it is the reduced substance
Br- lost an electron which means it is the oxidized substanced
Consequently, Cl2 is the oxidizing agent and Br- is the reducing agent.

Answer:

Bromine (Br) loses an electron, so it is the reducing agent.

What is the carbon cycle

Answers

the series of processes by which carbon compounds are interconverted in the environment, chiefly involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.

the cycle of thermonuclear reactions believed to occur in stars, in which carbon nuclei are repeatedly formed and broken down in the conversion of hydrogen into helium.

The volume of a pond being studied for the effects of acid rain is 35 kiloliters (kL). There are 1,000 liters (L) in 1 kL and 1 mc032-1.jpg 106 microliters (mL) in 1 L. What is the volume of this pond in microliters?

Answers

The volume of a pond being studied for the effects of acid rain is 35 kiloliters (kL). There are 1,000 liters (L) in 1 kL and 1 x 10^6 microliters (mL) in 1 L.

35 kL (1,000 L/ 1kL) (1 x 10^6 microliters / 1 L) = 3.5 x 10^10 microliters

The volume of this pond in microliters is 3.5 x 10^10 microliters

D The volume and the shape change to fill the new container.

2 Which of these correctly defines the pH of a solution?
A the negative log of the hydronium ion concentration
B the log of the hydronium ion concentration
C the negative log of the hydroxide ion concentration
D the log of the hydroxide ion concentration

Answers

Answer 1 : The correct option is C.

Explanation :

The property of liquid is, they have fixed volume but do not have fixed shape. when a liquid is transferred from one container to another then the volume remains the same, but the shape changes according to the shape of the container.

Answer 2 : The correct option is A.

Explanation :

pH : It is defined as the negative logarithm of the hydronium ion concentration.

The expression of pH is,

$pH=-log[H_3O^+]$

A stone falls from a ledge and takes 8 seconds to hit the ground. The stone has an original velocity of 0 m/s. How tall is the ledge? A. 313.6 meters B. 78.4 meters C. 1,254.4 meters D. 39.2 meters

Answers

The correct answer is letter A. We use the formula, v=vo + at to get the answer.

v=vo + at
v=0 + (9.8)(8)
v=78.4

y=1/2(vo + v)t
y=1/2(78.4)(8)
y=1/2(627.2)
y=313.6m

The answer will be A 313.6
