Answers
Answer:
Over millions of years, the shape of mountains on Earth’s surface can change to low hills and then to rolling plains. These changes are most likely caused by weathering and erosion.
These changes are most likely caused by weathering and erosion
What is weathering and erosion?weathering is the breakdown or dissolution of rocks and minerals. After a rock has been broken down, the bits of rock and minerals are carried away by erosion.
Erosion is a geological process in which natural forces like as wind and water wear away and transfer earthen materials.
How does weahering and erosion cause breakdown of large hills?weathering and erosion speeds up the process of breaking down of a mountain. Erosion speeds up tectonic processes beneath the mountains by lowering the weight of the mountain range. Wind, rain, and ice increase at higher elevations and directly effect the weathering and erosion process, causing mountain tops to weather more quickly.Hence the mountain will change into a valley over many years followed by eroding into rolling plains.learn more about Weathering and erosion here:

The table lists some organelles and functions. Only one pair is correctly matched.
Functions of Organelles

Nucleus Directs cell activity
Endoplasmic reticulum Breaks down sugar molecules to supply energy
Golgi apparatus Supports and protects organelles in the cell
Lysosome Produces proteins for the cell
Which organelle in the table is correctly matched with its function?
nucleus
endoplasmic reticulum
Golgi apparatus
lysosome
Answers
The function and the nucleus are appropriately matched. The nucleus, which serves as the cell's command centre, controls every activity. DNA and RNA, which make up genetic material, are in charge of encoding the instructions necessary for the cell to carry out its duties.
What happens in the case of nucleus in the cell division ?In addition to directing the replication of genetic material and the generation of new cells, the nucleus is involved in cell division. Additionally, the endoplasmic reticulum is well suited to its function.
A network of interconnecting tubes and sacs called the endoplasmic reticulum is in charge of the synthesis, processing, and movement of proteins and other chemicals inside of the cell. In order to provide the cell energy, it also breaks down sugar molecules.
The function of the Golgi apparatus is appropriately matched. The sorting, processing, and packaging of proteins and other molecules is carried out by the Golgi apparatus, a network of flattened sacs and tubes. By giving the organelles a protective covering, it also helps to sustain and safeguard the organelles within the cell.
The function of the lysosome is mismatched with it. The digestive enzymes in the lysosome, a membrane-bound organelle, are in charge of dissolving and recycling cellular waste and damaged organelles. It doesn't make cell-specific proteins.

b. are all the same weight
C. are all near the same age
d. are all of widely different ages
Please select the best answer from the choices provided
Answers
Answer: C. Are all near same age.
Explanation: Even-aged firewood management practices refer to the practice of clearing of trees that "are all near the same age"as this technique is usually adopted to maintain the proportion and continuity of various species of trees(thus, cutting of the trees of same age). This practice is employed to minimize the costs and attain a coeval and comrade group of trees. It proves quite beneficial in reestablishing the succession of a native breed. It involves the selection of trees at first depending on the size, desirable species, etc. followed by clearcutting of unmerchantable(undesired) trees. This technique is usually adopted to maintain the proportion and continuity of various species of trees.
KEYWORD- “Even- aged”which means clearing all trees that are even to all near the same age of tree.
