The two main distinctions between East Siberian greenish warbler and West Siberian greenish warbler is; 1. Their plumage patterns.
2. The wing bars which are used for communication.
West Siberian greenish warblers have a botanical name which they are referred as P. t. viridanus while East Siberian greenish warblers their botanical name is P. t. Plumbeitarsus. Plumbeitarsus have two wing bars while viridanus have one wing bar.
Their southern ring gradually changes the plumage patterns. The male greenish warblers are very good in singing to defend their territories and also to attract female ones.
Answer:
just look at the graph it literally tells you the answer
O Plant roots growing through concrete and splitting it
O Waves carrying sand away from a beach
OSmall rocks being carried along a river bed
The best example of physical weathering is as follows:
Thus, the correct option for this question is B.
Weathering may be defined as a process through which numerous rocks and minerals found on the earth's surface are considerably broken down into smaller fragments. The process of weathering is facilitated by different components like water, wind, ice, etc.
Physical weathering may be defined as a type of process that stimulates the disintegration of rocks, minerals, and soil components without undergoing any chemical change. Some examples of physical weathering are as follows:
Therefore, plant roots grow through concrete and split represents a process of biological activities or root wedging. So, the correct option for this question is B.

Answer:
Plant roots growing through concrete and splitting it.
Answer: I assume you meant biologist in this situation. A biologist is a type of scientist that studies living things, their environments, and how they live. Many different types of biologists exist, including research biologists, health care biologists, environmental biologists and biology educators. When it comes to research biologists they study different groups of living organisms around the world. Health care biologists are physicians, veterinarians, nurses and dentists. These types of biologists prevent spreading of infectious and deadly diseases and formulate ways to enhance the health of their patients. Biology educators teach students and up-and-coming biologists basic and sometimes advanced biological sciences in classroom, laboratory and field settings. Environmental biologists study ways to preserve the natural environments of different types of organisms. If you need an example they study animals in captivity and design new methods to help certain species live longer lives in their natural habitats.
Explanation: Hope this helps.
Answer: Forces like wind and water move the rock pieces. They mix with matter like sand to become sediment. Weathering and erosion help shape Earth's surface. They are part of a process called the rock cycle.
Explanation:
During S phase, DNA replication occur during the cell cycle for each daughter cell to receive a complete copy of DNA.
A cell'sgrowth and division are accompanied by a sequence of processes known as a cellcycle.
A cell spends the majority of its time in what is known as interphase, where it develops, duplicates its chromosomes, and gets ready to divide. The cell then exits interphase, goes through mitosis, and finishes dividing.
Following this, the celldivides into two daughter cells, distributing one copy of the duplicated material to each. When each daughter cell has its own outer membrane around it, the cell cycle is finished.
Genetically speaking, the parentcell, together with the two brand-new daughter cells, are all the same.
Prior to mitosis and cell division, DNA replication takes place during the S phase (also known as the Synthesis phase) of the cell cycle.
Thus, the DNA replication occur during Sphase of the cell cycle.
