Water reacts with minerals in some rocks and very slowly dissolves the rock. What type of weathering does this demonstrate?
Answer:
Salt wedging
Explanation:
Salt wedging is a natural phenomenon which occurs in rocks and stones. It is a physical weathering process. It is a process by which water enters into the small cracks on the rocks and form salt like NaCl and thereby enlarging the cracks.
Most water contains dissolved salts and when water enters into the small cracks of the rocks, the salt begins to grow and it exerts pressures on the walls of the crack thereby enlarging the cracks.
This type of phenomenon is mostly seen near the seacoast and in the arid regions.
Thus water reacts with the minerals in the rock and slowly dissolves the rock in salt wedging weathering process.

Why do the chromosomes line up in the middle of the cell
Answer:
QUESTION:
Why do the chromosomes line up in the middle of the cell?
ANSWER:
Chromosomes line up at the metaphase plate, under tension from the mitotic spindle. The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase, the spindle has captured all the chromosomes and lined them up at the middle of the cell, ready to divide.
Explanation:
Hope that this helps you out! :)

Suggest reasons for the color patterns of the frog and its lack of color on the ventral surface.
Answer:
To save itself.
Explanation:
The color patterns of the frog and its lack of color on the ventral surface allows the frog to protect itself from their predators because the frog changes its colour and the predators are unable to see them. The color patterns of frogs and their lack of color on the ventral surface allow frogs to escape from their predators. If the frog does not change its colour, the predators will see them and the frog will be catch by its predators and feed on them so this is the reason that frog changes colour or the presence of colour patterns.

What kind of information can scientist get from soft body parts that they cannot get from hard body parts?
Answer:
Function and working mechanism.
Explanation:
Information such as function and working mechanism etc can a scientist get from soft body parts that they cannot get from hard body parts because these soft body parts perform their work continuously and we can study it through a number of ways and methods. The working mechanisms of hard body parts can't be study because they are not visible to any instrument and occurs inside their structure so that's why function and working mechanism are the information given by the soft body parts.

Why do we use specific terminology when referring to the gender and species of common domestic animals?
Answer:
To know which exact organism you are referring to, and there is no confusion about it.
Explanation:
To identify organisms, we usually use two names. The common name and the scientific one.
Scientific name: binomial nomenclature.
The scientific name designates a species through binomial nomenclature. The binomial nomenclature is a standard agreement used to identify different organisms. It has international validity, and it does not change among regions or languages. One binomial name is used only on one organism and can not repeat. It is composed of two Latin words: gender and the specific name. Many species might share the same gender for being very similar, so the specific name is used to identify each species.
Common names:
These are informal names, determined by the people of a region or area, that speak the same language. They are regional names, so they change from region to region, even when referring to the same organism. Usually, these names designate only organisms that have importance for the people. The same name might refer to different organisms, and in many cases, the same organism might receive many names. For this reason, there might be confusion when using only common names to talk about a species.
If we need to refer to a particular organism, we should always use the scientific name to avoid confusion. As it is internationally recognized and accepted, anybody can know which species you are talking about, independently of the region or the language. In most cases, people mention a species using the scientific name together with many of its common names.
