The correct answer is all of the above.

An uncomformity can be defined as the contact source between two rocks in which the upper unit is younger than the lower unit is older. For example: 400 million year old sandstone was deposited on the 600 million year old sediment. There are three types of unconformities : disconformities, angular and nonconformities.

Describe the composition of semen
Oduvanchick [21]

Answer AND Explanation:

The seminal vesicle produces an alkaline fluid which contains nutrients for the spermatozoa. Near this point is situated the prostate gland whose secretion is alkaline to neutralise the vaginal fluids. It also activates the sperms. The cowper's' gland secretes alkaline fluid that neutralises the acidity along the urethra. All the fluids combine with the spermatozoa from the vasa deferentia to form semen.

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:

<u>Year                       Calculation         Est. Population</u>

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

<u>6th yr                      13,979*105%          </u><u>14,678</u>

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