It should be karst limestone and it forms by erosion of rocks such as limestone that dissolved in water in a process called chemical weathering :)
Answer: the answer to this question can be this-
Explanation:
it can be single-celled organisms like an amoeba.
who divide itself by binary or multiple fission to reproduce offspring which is same copies of them known as clones.
Answer:
option a. streak, pour
Explanation:
The best method to isolate single bacterial colonies is the "streak-plating" method.
The "streak-plate" procedure is used to isolate pure cultures of bacteria or also colonies, from mixed populations by mechanical separation. Millions of cells form a colony, they grow in a cluster on an agar plate. With this method, a mixture of cells is spread over the surface of a agar-based nutrient in a petri dish, that makes that less bacterial cells are deposited at widely separated point on the surface and, after incubation, they develop into colonies.
On the other hand, the best method to count colonies is the pour plate method. It helps to enumerate bacterial cells in a mixed sample, often used to count the number of microorganisms in those samples, which are added to a molten agar medium before its solidification occur. The result is colonies uniformly distributed throughout the solid medium when the appropriate sample dilution is plated.
The question is not given. You just placed some statements. Apparently, here you have some definitions to pair with the type of elements. So, I will separate the statements as per my best understanding. If the question requires anything else tell me to give you more details.
<span>1. Metalloid
Metalloid is an element that has properties in between metals and non metals, this is metalloids have some properties of both.
Then you can pair it with ---> moderate ability to conduct heat and electricity
2. noble gas
The elements that are knwon by not reacting with other elements are noble gases.
Then, pair this with ---> will not react with other elements.
3. metal:
Metals are malleable, polishes to a luster and are good conductors of heat and electricity.
Then pair metal with ---> malleable, polishes to a luster;
conducts heat and electricity well
4) non metal gaseous: non metal are poor conductors
So, pair this with ---> does not conduct heat or electricity well
Given that the question is no

Answer:
Through evolution, periwinkle populations with a history of predation by crabs have become less vulnerable to crab predation.
