Hi there!

<u><em>Answer: Robert Koch</em></u>

Explanation: In 1890, Robert Koch created a series of test to assess the germ theory of disease. In 1676, bacteria was first observed by Anton Van Leeuwenhoek. In 1859, Louis Pasteur disproved spontaneous generation and developed the germ theory of disease. In 1910, Paul Ehrlich created the first synthetic antibiotic.

Hope this helps!

Robert Koch is the scientist who created tests that helped confirm that bacteria and other microorganisms cause a variety of diseases. He is a German physician and a microbiologist who is known in identifying specific causative agents in a number of illnesses which includes cholera, tuberculosis and anthrax. Due to this contribution to medicine, he received a Nobel Prize in 1905.<span />

Give an example of two types of cells that never go through cell division once fully formed.
AnnyKZ [126]

Answer:

The two types of cells that never go through cell division once fully formed are nerve cells and muscle cells.

Explanation:

The nerve cells and the muscle cells not undergo cell division after formation, because they can never re grow or cannot be repaired once they are mature. We should take good care of it once they are matured. They just under division from being baby to teenagers after that they stop undergoing cell division. This is true for both elephants as well as human beings. This thing is also applicable in case of bones.

In the word "claustrophobic" phob is the_____.
snow_tiger [21]

Correct answer: A). Root

The part of the word that can not be broken down is called root word. In the word claustrophobic ''phob'' is the root word. It can not be suffix as a suffix are added after the root word. It cannot be prefixed as it is added before the root word. Here the prefix would be ''claustro'' and suffix would be ''ic''. It cannot be affixed as it contains both suffix and prefix.

Hence, the correct answer would be option A.

A hypothetical three-step metabolic pathway consists of the intermediates W, X, Y, and Z, and the enzymes that catalyze the reac
GenaCL600 [577]

Answer:

ZBWCYAX

Explanation:

Equation for the intermediates: Z↔W↔Y↔X

1) B catalyzes the breakdown of Z, therefore inhibiting B leads to the build up of Z.

2) If enzyme C is inactive then the organism will not  receive Y to grow, thus Y is a by-product of C.

3) If A is inhibited then W, Y and Z build except for X, thus it make sense that A catalyzes a reaction that leads to X as a by-product.

4) Inhibiting C leads to the reaction toward making Z and W, thus it catalyzes the breakdown of C directly and Z indirectly.

Is paper abotivc or biomtic
Lana71 [14]

Hi there!


Biotic means that something is living, and abiotic means something isn't alive. Paper, since it came from trees, a living thing, is a biotic factor.


Hope this helps!

Message me if you need anything else! I'd be happy to help you! :D

Ecosystems include food webs that show predation and prey interactions among organisms. But ecosystems have many more relationsh
AnnZ [28]

Answer:

Explanation:

Food webs describe the relationships — links or connections — among species in an ecosystem, but the relationships vary in their importance to energy flow and dynamics of species populations. Some trophic relationships are more important than others in dictating how energy flows through ecosystems. Some connections are more influential on species population change. Based on different ways in which species influence one another, Robert Paine proposed three types of food webs based on the species of a rocky intertidal zone on the coast of Washington (Ricklefs 2008, Figure 2). Connectedness webs (or topological food webs) emphasize feeding relationships among species, portrayed as links in a food web (Paine 1980). Energy flow webs quantify energy flow from one species to another. Thickness of an arrow reflects the strength of the relationship. Functional webs (or interaction food webs) represent the importance of each species in maintaining the integrity of a community and reflect influence on the growth rate of other species' populations. As shown in Figure 2, limpets Acmaea pelta and A. mitra in the community consume considerable food energy (energy flow web), but removal of these consumers has no detectable influence on the abundance of their resources (functional web). The most effective control was exerted by sea urchin Stronglocentrotus and the chiton Katharina (Ricklefs 2008).
