What do we call the evolution of living organisms on Earth over periods of time?
A.Biological Evolution B. Geological Evolution C. Environmental Evolution D. Living Evolution
Answer:
I think A
Changes in populations accumulate over time;
this is called evolution. The fossil record shows us that present day life forms evolved from earlier different life forms. It shows us that the first organisms on Earth were simple bacteria that dominated the Earth for several billion years.
Answer:
A: Biological Evolution
Explanation:
None of these terms actually exist. Evolution is simply called "evolution" and can be applied to multiple things. However, it would be A because organisms aren't geological, as that applies to the Earth itself, the environment isn't changing all at once with a certain organism either, and D honestly on it's own just doesn't make sense at all, so it would be A.

what happens to waste material in surface mining?
Answer:
Your answer is that mining activities increase the volume and rate of exposure of sulfur-containing rocks to air and water, creating sulfuric acid and dissolved iron. This acid run-off dissolves heavy metals such as copper, lead and mercury which leach into ground water aquifers and surface water sources, harming humans and wildlife

The diagram below shows the branching tree diagram for humans. The text box below it shows the set of derived shared characteristics for the branching tree.
A slanting, horizontal line is shown. On the extreme left, there is a label that says Common Ancestor. Along the slanting, horizontal line there are five dots labeled from left to right as 1, 2, 3, 4, and 5. There is one vertical line between each of the consecutive five dots. The lines are labeled from left to right as Perch, Frog, Pigeon, Rats, and Human. A text box below the branching tree diagram is labeled Derived Shared Characteristics. In the box it says from left to right, Terrestrial during all stages, Jaws, Walking on two legs, Mammary glands and hair, and Four limbs.
Look at the possible derived shared characteristics, shown in the text box. Think about where these should be placed along the branching tree diagram. Where in the branching tree would you most likely write "lives on land during all life stages"? Explain your answer.

Which of the following is a way in which elements and compounds are different?
O A. Elements are pure substances, but compounds are not
B. Compounds can be broken down by physical changes, but elements cannot.
C.
Elements are made of identical atoms, whereas compounds are made of
identical molecules,
D. A compound contains many different kinds of elements, whereas an element
contains many different kinds of atoms.
Answer:
C. Elements are made of identical atoms, whereas compounds are made of identical molecules.
Explanation:
Elements are made of identical atoms, whereas compounds are made of identical molecules because elements are made of atoms of only one kind while on the other hand, compounds are the pure substance that is made of molecules that is similar as well as different from one another. Both element and compound are pure substance. Compound can be broken down by chemical means whereas elements can not be broken down.

Climatology studies climatic change, and is an atmospheric science.
what cell types is a haploid
Answer:
Gametes
Explanation:
Haploids only contain one type of chromosome. Meiosis results in the production in gametes that are haploid.
answer this question! :)
Answer:Tt
Explanation:50% Tt and 50% tt and the only way to do it with a recessive trait is Tt since the other parent has to have tt
Question #1
Which statement about meiosis is true
Answer:
A.
Explanation:
The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell. Meiosis has both similarities to and differences from mitosis, which is a cell division process in which a parent cell produces two identical daughter cells.

7. Why is it so unlikely for a girl to get a disorder like Duchenne Muscular Dystrophy
Answer:
Because it takes a very long time and an interesting mindset.
Explanation:
People don't really have an explanation for the things that we do they just suddenly build up inside us
Answer:
This is because the mutated gene responsible for Duchenne is located in the X chromosome. Girls have two X chromosomes, meaning that the body usually inactivates the chromosome that carries the mutation. The female will carry the mutation, but manifest little to no symptoms of the disease.
Explanation:
I hope that this helped you ;)
Which organelles are different between animal cells & plant cells? pls 45 minutes till this assignment is due
Answer:
Plants have cell walls provide support and gives the plant its shape. Plant cells have chloroplasts, but animal cells do not. Chloroplasts enable plants to perform photosynthesis to make food(glucose). Plant cells usually have one or more large vacuole, while animal cells have smaller vacuoles, if any are present.
Cell Wall and Chloroplasts ( Plants have them, animals don't)
Lysosomes and Centrosome (Animals have them plants don't)
