All objects having mass

The answer would be all objects having mass because if the object has mass the gravitational pull can get a hold of that object and bring it to its normal place for example an object on earth like lets say a ball, if you throw it up in the air it always comes back down. That is because it has mass.

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.

What characteristic do protozoa and fungi share?
Nadusha1986 [10]

Answer:

<h2>letter A</h2>

Explanation:Whittaker placed bacteria in their own kingdom, Monera, because of fundamental organizational differences between prokaryotic bacterial cells, which lack membrane-enclosed nuclei and organelles , and the eukaryotic cells of other organisms that possess internal membranes. Plantae, Fungi, and Animalia consist of complex, multicellular eukaryotic organisms that differ from each other in details of cell structure and in how they secure and process energy. Protista is a collection of single-celled eukaryotic organisms and simple multicellular forms, some animal-like, some plantlike.

<h2>letter b</h2>

Molecular evidence, particularly from ribosomal ribonucleic acid (RNA), suggests that the five-kingdom scheme is also too simple. Some biologists believe that Protista should be partitioned into three or more kingdoms. Similarly, kingdom Monera contains two very biochemically distinct groups of prokaryotes: archaebacteria, and eubacteria. A proposed system acknowledges this ancient evolutionary split by creating a higher level of classification, domain, above kingdom. This system distinguishes three domains: Archaea, Eubacteria, and Eukarya (containing protists, plants, fungi, and animals).
