Why is the impermeable layer important? *

1 answer:

3 0

There is much more fresh water underground than on the surface. A rock layer must be porous and permeable to be a good aquifer. An impermeable layer makes up the bottom of an aquifer. The water table rises and falls with additions or subtractions to the groundwater system.

How does the skeletal system of an embryo differ from that of an adult?

fredd [130]

Almost the entire system of an embryo is made of cartilage, whereas that of an adult is mostly made of bones.

An embryo is a multicellular diploid eukaryote in an early stage of embryogenesis, or development. In general, in organisms that reproduce sexually, an embryo develops from a zygote, the single cell resulting from the fertilization of the female egg cell by the male sperm cell.

Biologically, an adult is a human being or other organism that has reached sexual maturity.

The correct answer between all the choices given is the first choice or letter A. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

To disprove spontaneous generation, pasteur used swan-necked flasks to allow entry of air to the boiled broth while blocking con

Andru [333]

Pasteur produced a nutrient broth and placed equal amounts of it in two long necked flasks. One flask had a straight neck (control) and the other had a swan shaped bent neck (being tested). He boiled the broth in both the flasks to kill any living organism that might be surviving on it. The two flasks were then left in the open air of the room to cool down. After several days passed, Pasteur noticed that the broth in the straight necked flask had changed its color but the swan necked flask didn't. From this observation he was able to conclude that the straight necked flask had let the organisms enter the flask and contaminate the broth. The swan necked flask blocked the entry of the organisms from the open air and thus remained unaffected.

A scientist is studying the population of a particular species of beetle in an ecosystem. The beetles currently have an estimate

Snowcat [4.5K]

Answer/Explanation:

Given an estimated beetle population of 11,500, of which it is estimated to increase approximately by 5% each year, we can calculate the estimated population for each year as follows:

Year Calculation Est. Population

1st yr (current yr) 11,500

2nd yr 11,500*105% 12,075

3rd yr 12,075*105% 12,679

4th yr 12,679*105% 13,313

5th yr 13,313*105% 13,979

6th yr 13,979*105% 14,678

The above is how the table would like showing the estimated population for each year.
