Even-aged management practices involves clearing trees that
are all the same height
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.

C. Are all near the same age

KEYWORD- “Even- aged”which means clearing all trees that are even to all near the same age of tree.

D) deposition and compaction

Answers

Answer:Its C

Explanation: i took the test trust me

physical-weathering is likely the cause of the underground cave system.

Rocks, minerals, and soils disintegrate through a process known as physical weathering, sometimes known as mechanical weathering.

Abrasion is the main physical weathering process (the process by which clasts and other particles are reduced in size). Temperature, pressure, frost, root movement, and burrowing animals can all cause physical weathering.

For instance, physical weathering will expose more surface area through the use of cracks, speeding up the pace of deterioration.

Which organelle in the table is correctly matched with its function?
nucleus
endoplasmic reticulum
Golgi apparatus
lysosome

Answers

Nucleus directs cell activity.

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.
