which statement is true about relative dating and radioactive dating?
A. both use laboratory techniques to find an exact age
B. both use the method of superposition
C. both compare rocks to the earth layer they were found in
D. both compare the object to an event in history
Answer:
A. i'm guessing. Sry if im wrong
Explanation:
Answer: Both compare the object to an event in history.
Relative dating is a way to find the age of an object by comparing it to the known age of things found in the layers of Earth around the object. The age can also be related to a known event in time. This method provides an estimated age and is typically shown as a range of years.
Radioactive dating is done by examining the atomic particles found in an object. The atomic particles decay over time at a predictable rate. Scientists are able to measure the rate of decay to establish the age of the material. (This method provides a very specific age)

Marcus read that systems provide feedback, or the return of information. Feedback can either cause a change in the system or keep it stable. Melting glaciers are an example of positive feedback. Why is this considered positive feedback?
A. Melting glaciers would add more water to the hydrosphere, making it wetter.
B. Melting glaciers would change the land around it, speeding up erosion.
C. Melting glaciers would let the uncovered air and land warm, which speeds up the melting.
D. Melting glaciers would mean more ice at its top, which would slow the glaciers melting.

Which is the most likely to be reduced?
A. Cu2+
B. Fe3+ C. Fe2+
D. Zn2+
Answer: B. Fe3+ might be the answer
The ion Fe3+ will be most likely to be reduced.
What is reduction?The elimination of oxygen is referred to as reduction.
What is Fe3+?It will be name as iron ion. Its atomic number is 26. After loosing 3 electrons it will become Fe3+ .
It can be seen that iron atom will loose its electrons. The ion Fe3+ will be most likely to be reduced. In electrolysis, positive ions travel more toward the electrode. They will be decreased after receiving electrons and get easily reduced.

The ovule and stigma are both located on the male reproductive part.
Answer:
The ovule and stigma both produce the plant's fruit and seeds.
Both the ovule and the stigma are a part of the pistil which is a female reproductive part of a flower.
What is a flower?
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants . The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing resulting from cross-pollination or allow selfing when self-pollination occurs.
There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species.
Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positioned so that the pollen can land on the flower's stigma. This pollination does not require an investment from the plant to provide nectar and pollen as food for pollinators.

Nitrogen (N) has an atomic number of 7 and an atomic mass of 14. Which of the following correctly shows the electron arrangement for nitrogen?
2, 7
2, 5
2, 2, 3
2, 8, 4
Answer:
B) 2,5 seems to be the correct answer
Explanation:
The atomic mass is 14, and the atomic number is 7. Knowing this, the atom must have 7 electrons. A and D are not correct because they both include a number that is not 7 if you add. B or C seem to be the best answers, I think it's B because C has the same number repeated twice in it. I might be wrong but I know that the answer has to be either B or C.

2,2,3 shows the correct electron arrangement for nitrogen.
What is an electron arrangement?An electron arrangement is the way in which electrons are arranged in an atom .
What is nitrogen?Nitrogen is a non-metallic element of Group 15 [Va] of the periodic table.Nitrogen is a colourless and odourless gas that is the most plentiful element in Earth's atmosphere and is a constituent of all living matter.In the electronic configuration of nitrogen the first two electrons will go to the 1s orbital. Since 1s orbital can only hold two electrons the next 2 electrons of nitrogen goes to the 2s orbital. The remaining three electrons will go in the 2p orbital.
Therefore, the electron arrangement of nitrogen will be 1s² 2s² 2p³.
