(a)increased earthquakes
(b) changing ocean circulation
(c) extinction of animals
(d) changing earth's position on its axis
Answers
The correct answer is - (b) changing ocean circulation.
The ocean currents are very important when it comes to the climate. The movement of the tectonic plates though, over time, is changing their patters. The changes appear because of the movement of the land masses, so there can be situations where the ocean currents are interrupted by a moving land mass, or more space to be opened up for an already existing ocean current with the moving away of a land mass of its path. Those movements and spaces in the water bodies are affecting the direction and the temperature of the ocean currents, and those changes will reflect on the climate on the regions that they are influencing.

Answer:
The correct option is a.
Step by step explanation:
The given number is
In the given number two digits are on the left side of the decimal and 6 digits on the right side of the decimal.
We have to round the given number to four significant digits. The left side of the decimal will remains the same but the right side of the decimal will rounded to two decimal places.
Find third digit after decimal. If third digit is greater than 5, then add 1 in second digit. If third digit is less than or equal to 5, then second digit will remains same.
Since third digit is 7, therefore the second digit will become
Therefore option a is correct.

Yes, it is alive according to the characteristics of life of plant, i.e.,
1.it has a definite structure and organization : organic (carbon-based molecules)
2. it metabolizes : its leaves are green and the green color is due to chlorophyll.
3. it maintains internal environment/homeostasis : it does not dry up (keeps the water level inside at a constant level)
4. it can reproduce : that's why it is not extinct or endangered
5. it grows : giving it a trim every few weeks is a good option
6. plants generally grow towards an area with more sunlight if it is not always exposed to sunlight.
7.bush has thorns as an adaption (which is a product of evolution) to defend itself
What are the seven characteristics of plant life?
Like animals, fungi and all other living organisms, plants undergo different life processes that enable them to grow and reproduce. The seven life processes involve gaining nourishment, excreting waste material, growth, reproduction, sensitivity, respiration and movement.
What are photosynthetic characteristics?
A large number of plant characteristics contribute to whole-plant net photosynthesis, e.g. plant height, leaf area, leaf geometry, photosynthetic capacity, dark respiration. Yet all studies discussed so far have considered optimization of one characteristic with all other characteristics held equal.

Answer: D. cell
Explanation:
The cell theory suggested three proposed statements those were all living things are composed of cells, the cell is the smallest entity of life and all cells formed from the pre-existing cells. This discovery is attributed to Robert Hook, who first began the study of cells in his self constructed microscope. But two scientists named as Matthias Schleiden and Theodor Schwann were the contributors of this theory in 1839.
