Answer:
false
Explanation:
beacause rock material are every were in sand in dirt and even in your back yard.
B. The genetic offspring are exactly like the parent cell.
C. There are 23 chromosomes from each parent cell passed on to the offspring.
D. Meiosis goes through 2 stages of division, Meiosis I and II.
Answer:
I would say it is B.
Explanation:
In Meiosis, specifically in Prophase 1, it creates genetic variation. Crossing over occurs in that stage
Salt as well as a lower temperature raises the density, so it would be "cold, salty water."
salty water or warm should be ur answer
Salts,mostly potassium and sodium are known as electrolytes and the body needs them in very specific amounts for proper function. Any significant imbalance of these levels can even be fatal if not corrected quickly.
The normal level of sodium in the body is 135 - 145 mmol/l in the blood while for potassium it's 3.5 to 5.0 mmol /l.
Loss of salts e.g. due to sweating may reduce these levels and so drinking plain water may replenish fluid loss but since plain water has no salts, the salt deficit remains and is in fact aggravated by the increase of plain fluid.
But drinking fluid that has electrolytes both replaces lost fluids and and at the same replenishes lost salts keeping the body functioning well .
a long-term change in the Earth's climate
a long-term increase in the Earth's average temperature
a long-term change in the climate of a region or a city
solar heat that is radiated out into space
Answer:
I think it's the 2nd one
A.skin
B.rigid tubes
C.exoskeleton
D.other muscles
Unlike humans, whose bones and muscles help them to move, in insects the structure that protects them and also provides them the structure is called an exoskeleton.
Insects are referred to as invertebrates, unlike mammals. This states that insects tend to lack an internal skeleton. Instead of an internal skeleton, the insects possess an exoskeleton that is specifically situated external side of their bodies. The exoskeleton is useful in the following ways:
Thus, we can conclude that the exoskeleton is the insect’s structure that helps in protecting them and further provides them the structure. Hence, the correct answer is option C.

B) the relative age of the rock
C) the absolute age of the rock
D) the level of radioactive isotope decay in the rock-
-At first I thought it was the date the rock was formed...But I think it wrong, so I looked over the text and now I'm thinking they want it to answer eider B-C relative or Absolute age of the rock. So I can cross off A and D. And by doing that, I had to take a look into my notes, and I notice my notes aren't the best but from what I know, Absolute determines whether it gives up the true ‘age’ of a rock or fossil. And Relative doesn't provide a “true age’’... But now that I'm thinking on it absolute looks to see if it mainly organic or tissue, while Relative mainly sedimentary rocks. So I'm thinking it B now, but I feel like I'm confusing myself with all this. So I wanted to understand this better and get a clear answer to this. If my answer wrong, can I get a short explanation as to why?-
