Because carry out all the functions in the human body necessary for living. Proteins make up hormones that are required for living. Insulin - responsible for stabilising blood sugar. Haemoglobin - responsible for carrying oxygen around the body. Melatonin - responsible for helping us get to sleep. Adrenalin - responsible for the flight-fight-freeze response. There are many more but here are just a few.

Answer:The answer is tiny organisms known as cyanobacteria, or blue-green algae.

Explanation:

These microbes conduct photosynthesis: using sunshine, water and carbon dioxide to produce carbohydrates and oxygen increase. Additionally, some sources you could use that I used to answer this question was

Which sentence represents a hypothesis? environmental conditions affect the pollination of plants. boil 100 milliliters of water

schepotkina [342]

The best answer for this question would be:

environmental conditions affect the pollination of plants.

Because it depicts the starting information or theory that the researcher is stating. His theory is that the conditions of the plant will affect the plant, and therefore experiments on the procedure to prove his theory.<span> </span>

Is there a picture you forgot to post with the question?

In the problem you mention, which I assume comes from the study of finches in the Galapagos, some birds evolved to have different beaks, depending on the food available. Depending on what kind of seeds there are, different beak sizes were selected for, with those with the right fit eventually winning out over the rest on the individual islands.

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).
